Mars rover may get one-way ticket BBC News
The chief scientist on Nasa's Mars rover mission is contemplating whether to send Opportunity into a large crater with no means of getting back out.
Rover scientists have not yet found a way out for Opportunity
The decision could commit the rover to spending its final days exploring Victoria Crater, a 60m-deep (200ft) depression on Mars' Meridiani plains. Steve Squyres said Opportunity would probably be sent in to explore the bowl even if no escape route was found. But he stressed his team would do its best to find an exit path first.
QUOTE("Steve Squyres @ chief scientist - Mars Rover programme")
Even if we find there's no way out, we'll probably go in anyway, because there's just so much to be gained
Opportunity has explored other craters on Meridiani Planum; indeed, it even came to rest in one after descending to the Martian surface in January 2004; but Victoria Crater is a much more challenging proposition. "You've got to realise this is a big, big crater for a little rover like this. The biggest thing we ever explored with Opportunity was Endurance Crater, which was 150m in diameter. "This is six times that, so it's huge," Professor Squyres told the BBC News website.

Exit strategy
Speaking to me at the Open University in Milton Keynes, where he was due to give a lecture, he explained: "We have found a way in, we haven't found a way out yet. It turns out this rover is better at going downhill than it is at going uphill. "I don't want to go into this crater until we've either found a way out or sort of convinced ourselves that there probably isn't one. In other words, I want to go in with knowledge of the consequences.
The Opportunity rover was pictured at the edge of the crater
"But even if we find there's no way out, we'll probably go in anyway, because there's just so much to be gained." The crater has high walls with layers of exposed rock that should reveal significant new information about the planet's geological past. "The thing Victoria offers is first of all, it is several times deeper than anything we've seen before so we're getting a longer geologic record," the researcher based at Cornell University in Ithaca, US, explained. "The other thing is that because Victoria is such a large crater with so many points along the crater rim at which we can do geology, we can look not only at vertical variations in the geology, but we can look at horizontal variations, which we couldn't do before." This should allow scientists to track how features of a particular rock unit change with distance. For instance, it can give information about the extent and shapes of ancient Martian sand dunes. The rover programme's principal investigator said Opportunity had just begun a partial, clockwise circumnavigation of the 800m-wide (half a mile) bowl to scope out its geology.

Future exploration
Professor Squyres also talked about future exploration of the Red Planet. In addition to surface exploration, he said a mission to return samples of Martian rocks to Earth should be high on the list of priorities for scientists. "I think it's going to be particularly important to bring rocks back. I'm a big fan of in-situ robotic exploration; that's what I do. But the best scientific instrumentation is always going to exist in laboratories on Earth.
[i]Geologists are keen to get close to the crater's walls
"Return samples are kind of like the gift that keeps on giving. If you don't use them all up when you bring them back, then you preserve samples so they can still be around a generation later when you have a new generation of scientists and a new generation of scientific instruments. "The best science ever done with lunar samples collected back in the Apollo era is being done today with brand new instrumentation." This, he said, could be vital for answering the questions of whether life once arose on the Red Planet and also exactly how old Martian rocks are.
Steve Squyres says sample return should be a science priority
Opportunity has been exploring Mars' Meridiani Plains since January 2004. Its "twin", the Spirit rover, continues to explore Gusev Crater on the other side of the Red Planet. Both robots have continued working far beyond their designed mission lifetimes. Professor Squyres said he had no idea when the rovers were likely to cease functioning: "It could be two years from now, it could be tomorrow," he said. For the moment they are working well, despite showing some signs of wear and tear. Opportunity has now driven more than 9km (5.6 miles) across the planet's dusty surface, examining rocks and studying the Martian environment. It has found strong evidence that shallow waters periodically flowed over its region of Mars many millions of years ago. On Tuesday, Professor Squyres spoke at the Centre for Earth, Planetary, Space & Astronomical Research (Cepsar) Lecture at the Open University in Milton Keynes. He also gave a lecture on Wednesday at the Geological Society's William Smith Meeting 2006 in London.

States sign nuclear energy pact BBC News
An international consortium has signed a formal agreement to build an experimental nuclear fusion reactor.
Iter represents the biggest scientific undertaking since the space station
The multi-billion-euro project known as Iter - or "the way" in Latin - will aim to produce energy from nuclear reactions like those that fuel the Sun. If successful, it could provide energy that is clean and almost limitless. The project, which will be based in France, follows years of talks between South Korea, Russia, China, the EU, the US, India and Japan. If all goes well, officials will build a demonstration power plant before rolling out the technology to the world. Iter says electricity could be available on the grid within 30 years.

Big reward
"Fusion could become the dominant source of electricity on Earth in a century or so - we have to work to try to get it," Jerome Pamela of Iter told the BBC.
FUSION: Necessary investment
"Not doing so would be irresponsible because the outcome could be huge, great for humanity," he said, adding that it was nonetheless a "very, very demanding challenge" to essentially imitate the work of the Sun on Earth. In a fusion reaction, energy is released when light atomic nuclei - the hydrogen isotopes deuterium and tritium - are fused together to form heavier atomic nuclei. To use controlled fusion reactions on Earth as an energy source, it is necessary to heat a gas to temperatures exceeding 100 million Celsius - many times hotter than the centre of the Sun.
QUOTE("Roger Higman - Friends of the Earth")
Isn't the money that's being spent on fusion better spent on proven technologies rather than chasing a dream?
The technical requirements to do this, which scientists have spent decades developing, are immense; but the rewards, if Iter can be made to work successfully, are extremely attractive. One of the attractions of fusion is the tiny amount of fuel needed. The release of energy from a fusion reaction is said to be 10 million times greater than from a typical chemical reaction, such as burning a fossil fuel.

Lead partner
The project is based in Cadarache, about 60km (40 miles) from Marseille in the Provence-Alpes-Cote d'Azur region. It currently hosts Tore-Supra, one of the existing European centres for fusion research.
QUOTE("ITER - NUCLEAR FUSION PROJECT")
Fusion is the nuclear process that operates at the core of the Sun
  • Project estimated to cost 10bn euros and will run for 35 years
  • It will produce the first sustained fusion reactions
  • Final stage before full prototype of commercial reactor is built
Work to clear a wooded area for the Iter buildings will begin in the spring. Ancillary and power facilities and a visitors' centre will go up in 2008. The reactor itself will start to take shape in 2009. The French site was chosen after a long period of bartering between the Iter parties; and the EU, as the host bloc, is shouldering 50% of the five-billion-euro construction costs. The deal signed by ministers on Tuesday puts those negotiations into effect, establishing the international organisation that will implement the Iter fusion energy project. The signature took place at a ceremony at the Elysee Palace in Paris, hosted by the president of France, Jacques Chirac, and by the president of the European Commission, Jose Manuel Durao Barroso. After the signature ceremony, the first meeting of the Interim Iter Council will take place. The green lobby is opposed to the Iter project. It believes the benefits have been oversold and the difficulties and waste production issues underplayed. Roger Higman, policy coordinator for Friends of the Earth, told BBC News: "We face a very real energy crisis over the next 50 years which is to do with climate change; that we have to stop using coal, oil and gas. "The question we would ask is: isn't the money that's being spent on fusion better spent on proven technologies rather than chasing a dream that even its proponents say will take a hundred years before it's going to providing any of our energy answers?"
QUOTE("Nuclear Fusion")
  • The proposed Iter reactor is shaped like a doughnut - a Russian-conceived design referred to as a tokomak
  • Deuterium and tritium - isotopes of hydrogen - are fed into the reactor and heated to 100 million Celsius
  • A powerful magnetic field holds the hot plasma, or gas, away from the walls and squeezes to initiate fusion
  • Iter hopes to do this in bursts of 500 seconds; a commercial reactor would have to run for prolonged periods
  • In a commercial reactor, energetic neutrons are absorbed in a surrounding 'blanket' to drive a steam-turbine system

UN warning on e-waste 'mountain' BBC News
The world's richest nations are dumping hazardous electronic waste on poor African countries, says the head of the UN's Environment Programme (Unep). Speaking in Nairobi, Achim Steiner said consumerism was driving a "growing mountain of e-waste". Unep estimates that up to 50 million tonnes of waste from discarded electronic goods is generated annually. Improper disposal of e-waste can release hazardous chemicals and heavy metals into the environment. Mr Steiner made his comments at the opening of a week-long conference in Nairobi which will review the Basel Convention, aimed at reducing the movement of all types of hazardous waste. "The need for Basel is ever more evident in this globalised world," he said. "Accelerating trade in goods and materials across borders and across continents is one of the defining features of the early 21st Century."

Toxic waste
E-waste is thought to be the fastest growing part of municipal waste in the developed world. The decreasing cost of replacing computers, mobile phones and other electronic gadgets, and the speed with which technology goes out of date, mean there is more and more to be disposed of. Traditionally, much of the waste found its way to Asian countries such as China and India, but tighter regulations means more and more is ending up in Africa. A recent study by the Basel Action Network concludes that a minimum of 100,000 computers a month are entering the Nigerian port of Lagos alone. "If these were good quality, second hand, pieces of equipment this would perhaps be a positive trade of importance for development," said Mr Steiner. "But local experts estimate that between a quarter to 75% of these items including old TVs, CPUs and phones are defunct - in other words e-waste." When these are burnt, a common disposal method, it can release toxic fumes and leach chemicals such as barium and mercury into the soil.

International force
The conference will discuss how to tighten regulations to prevent this kind of incident occurring. In particular it will review amendments to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal which will tighten controls on shipments and disposal of e-waste. "We need to shine a brighter light on hazardous wastes - where they come from and where they end up," said Basel Convention Executive Secretary Sachiko Kuwabara-Yamamoto. The convention is meant to regulate waste in all of its forms, including e-waste. It came into force in 1992, and has since been signed by more than 160 countries. Members of the convention in Nairobi will also press those countries that have not yet ratified the treaty, such as the US, to do so. Also on the agenda will be a recent incident in Ivory Coast where noxious fumes produced by waste dumped around Abidjan killed at least 10 people and left more than 70,000 seeking medical treatment. Although there is no indication that the incident was caused by e-waste, the UN says the incident is indicative of the challenge facing African nations. "I sincerely hope that the tragedy in Cote D'Ivoire and the challenges of e-waste will serve as a wake up call to the Parties of the Basel Convention and other related treaties," said Mr Steiner.

US plans permanent base on Moon BBC News
US space agency Nasa has said it plans to start work on a permanently-occupied base on the Moon after astronauts begin flying back there in 2020.
Man first set foot on the Moon in 1969
The base is likely to be built on one of the Moon's poles and will serve as a science centre and possible stepping stone for manned missions to Mars. The US has already said it plans to build a new lunar spacecraft to succeed the last Apollo mission in 1972. Funds will be moved from space shuttle flights, due to be scrapped in 2010. The structure of the base and the exact duties of the astronauts stationed there have not been decided. Nor is it clear when the base will begin functioning.

Lunar outpost
"We're going for a base on the moon," Scott "Doc" Horowitz, Nasa's associate administrator for exploration, said. The agency's deputy head, Shana Dale, is quoted by the Associated Press news agency as saying that the "fundamental lunar approach" will be very different to earlier Moon missions.
A lunar spacecraft has already been commissioned by Nasa
Nasa has elected to build a lunar outpost rather than operate brief trips to the satellite as it did in the 1960s. Nasa is also expected to ask other countries - and businesses - to help it build the base. The permanent base will be built near one of the two poles, as these are felt to have a moderate climate and more sunlight - essential if the base is to use solar energy. "It's exciting," Shana Dale told the Reuters news agency. "We don't know as much about the polar regions." According to Reuters, funds for building the lunar base will be diverted from the space shuttle programme, which is to be phased out by 2010. After the Columbia space shuttle accident, US President George W Bush announced plans to send astronauts back to the moon by 2020. Nasa announced in August that the Lockheed Martin Corporation will build the next US spaceship to take humans to the Moon.
QUOTE("2020: HOW HUMANS WILL GO BACK TO THE MOON")
  • (1) The heavy-lift Ares 5 rocket blasts off from Earth carrying a lunar lander and a "departure stage"
  • (2) Several days later, astronauts launch on an Ares 1 rocket inside their Orion vehicle (CEV)
  • (3) The Orion docks with the lander and departure stage in Earth orbit and then heads to the Moon
  • (4) Having done its job of boosting the Orion and lunar lander on their way, the departure stage is jettisoned
  • (5) At the Moon, the astronauts leave the Orion and enter the lander for the trip to the lunar surface
  • (6) After exploring the lunar landscape for seven days, the crew blasts off in a portion of the lander
  • (7) In Moon orbit, they re-join the waiting robot-minded Orion and begin the journey back to Earth
  • (8) On the way, the service component of the Orion is jettisoned. This leaves just the crew capsule to enter the atmosphere
  • (9) A heatshield protects the capsule; parachutes bring it down on dry land, probably in California

Foetal cells 'to treat strokes' BBC News, science correspondent
A UK company is applying for permission to transplant stem cells made from human foetal tissue into the brains of stroke patients. Guildford-based ReNeuron has told the BBC it has convincing lab evidence that the cells could potentially regenerate brain cells damaged by a stroke. It has applied to the US Food and Drug Administration to carry out human trials on 12 stroke patients. However, opponents have said it is a "sick proposal". The ReNeuron team have successfully extracted stem cells from the developing brain area of a 12 week old aborted foetus. These cells have begun to specialise into brain cells and have the ability to rapidly generate brain tissue. According to Dr Eric Miljan, Reneuron's head of stem cell discovery, when the foetal stem cells were injected into the brains of rats in which a stroke had been induced their movement recovered. Tests showed that blood flow and brain activity were restored in the damaged area. Dr Miljan said: "We're very excited. There have been a battery of tests. There have been a series of animal safety experiments. And they work. "We feel that we are ready to go into patient trials." The company is to submit its research results to the FDA, and if the human trial is approved it could begin early next year.

Safety concerns
But the regulators will want to be satisfied that the trials will be safe and hold out a realistic chance of doing some good. In particular they will want to look closely at a crucial part of the treatment which involves genetically modifying the foetal brain cells. The researchers incorporate a gene called c-myc which is associated with normal cell division. However, when there are abnormalities with cells the gene can be involved in the uncontrollable replication of cells and lead to cancer. ReNeuron say they have safely harnessed this property by modifying this gene to make its action fully controllable. They add the modified version of the gene so that it can cause a small number of foetal stem cells to multiply when a chemical is added. In effect, this provides a biochemical way of photocopying the cells. The replication stops once the chemical is taken away.

Ethics case
Michael Hunt, ReNeuron's CEO, said: "We have proven with reams of experimental data that the system is fully controllable. "We have also shown that the cells we grow using this system show absolutely no abnormalities throughout the growth process. "It is very important for us to be able to demonstrate these safety characteristics before moving our therapy forward into stroke patients." Reneuron's idea is to produce unlimited quantities of stem cells from just one foetal tissue sample. According to Dr Miljan, this makes their treatment potentially commercially viable and ethically more acceptable. "We only take one single piece of tissue and for that we can grow up enough cells to potentially treat all eligible patients. "And we never have to go back to that tissue again. We can provide a renewable source of cells in order to treat a large patient population."

Holy grail
Joe Corner, of the UK's stroke Association, said the research was "very interesting". He said: "The Holy grail for stroke research has been to find a way of regenerating the damaged part of the brain. "Until now its been thought that the damage was irreversible. "Most treatments and therapies have relied on teaching the patient to use different parts of their brain through physiotherapy. "But we are beginning to see some promising signs in potential stem cell treatments and ReNeuron's approach does seem very exciting." However, John Smeaton, director of the Society for the Protection of Unborn Children, was completely opposed to the research. He said: "It's a sick proposal. It involves cannibalising an unborn child. "It's an unethical in every way - killing one member of the human race to help another. We are totally opposed to this."

Shuttle set for 'complex mission' BBC News
The crew of space shuttle Discovery are preparing to lift off on what Nasa says will be a "truly complex mission". Early on Friday, seven astronauts will embark on a tricky and hazardous bid to rewire electrics on the International Space Station (ISS). Discovery will launch from Kennedy Space Center in Florida at 2136 EDT (0200 GMT) - making it the first night lift-off since the Columbia disaster. The countdown clock started as scheduled at 0400 GMT this morning. "This is a truly, truly, truly complex mission," said Nasa's space operations chief Bill Gerstenmaier.

Spacewalk tasks
In three spacewalks, the astronauts will rewire the orbiting station, replacing its eight-year-old temporary power cable system with a permanent one. They will need to do this without interrupting the station's life-support and other critical systems. The job was made possible after the crew of the previous mission installed two huge electricity-generating solar array panels on the ISS in September. Discovery will also transport a new $11m girder weighing two tonnes to the ISS and install it during a spacewalk. "You have to prepare yourself for quite a number of very ugly contingencies or failures," Florida Today quoted Nasa's deputy station programme manager Kirk Shireman as saying. The mission, which Nasa says is one of the hardest yet for its astronauts, is vital for getting ISS construction back on pace. Construction of the station is well behind schedule following the two-year effort to return the space shuttle to flight following the Columbia disaster in 2003.

Night launch
The US space agency says it would prefer to launch Discovery during the daytime. But it must resume night launches in order to finish building the ISS before the shuttles are retired in four years. Daytime launches give cameras a better view of the tank as the shuttle climbs to orbit. Managers believe the shuttle's fuel tank has been improved to the point that foam debris shedding from the tank during lift-off - which triggered the Columbia accident - is no longer a threat. A briefcase-sized chunk of foam damaged Columbia's wing on lift-off, allowing superheated gasses to penetrate the heat shield as it returned to Earth in February 2003. All seven astronauts were killed in the disaster. For Discovery's lift-off on Thursday, Nasa will rely on backlighting from the shuttle's solid rocket booster to illuminate the tank for onboard cameras and radar systems which are set up to track debris. The crew - five men and two women - arrived at Kennedy Space Center on Sunday for final mission preparations. One astronaut, Sunita Williams, will be making a one-way trip. She is to remain aboard the space station, replacing Germany's Thomas Reiter, who will return with the rest of the Discovery crew on 19 December.

'Most websites' failing disabled BBC News
Most of the leading websites around the world are failing to provide the most basic accessibility standards for people with disabilities. Ninety seven percent of websites did not provide even minimum levels of accessibility, a new survey has found. Accessibility agency Nomensa tested the leading websites in five different sectors across 20 countries. Only three websites, including the British Prime Minister's site, achieved the minimum standards. The report, commissioned by the United Nations as part of its International Day of Disabled Persons, will make depressing reading for anyone committed to the idea of equal web access for all.

Multiple failings
"This is a global failure and we are very disappointed with the results," said Alex Metcalfe, head of client services at Nomensa. He added: "It is important for commercial, legal and moral reasons that websites put in place a strategy for accessibility, both in terms of quick wins and longer term improvements." Nomensa tested representative websites from five key sectors - travel, retail, banking, government and media. In the UK, the websites looked at included Marks & Spencer, Lloyds TSB, British Airways and The Guardian. The BBC's website was not included in the survey. The British Prime Minster's sites alongside the Spanish government site and the German Chancellor's site were the only three to conform to the most basic standards. In order to reach the minimum standards - tested against the Web Content Accessibility Guidelines (WCAG) - websites needed to provide adequate text descriptions for graphical content so that visually impaired people could 'read' pictures. 93% of the websites failed to meet those guidelines. A further 73% failed to make the grade because of their reliance on JavaScript for some of the website's functionality. JavaScript does not work with some screen readers used by those with impaired vision. Ninety eight percent did not follow industry web standards for programming code, meaning the foundations for web accessibility simply were not there.

Time to talk
Mark Gristock, marketing director of usability firm Foviance, is unsurprised by the results. "This is the same results we always get. The guidelines have been in place for seven years but they aren't actually checkpoints so people can interpret them in a variety of ways. What is needed is practical advice about what happens when you build a website. "Building dull, technically compliant websites is easy but building commercially successful sites that are also accessible is not," he said. It was time to share examples of good practice so that web developers could start incorporating accessibility into the design of websites, he suggested. "Accessibility consultants and organisations for the disabled clutch their knowledge of user requirements to them like they are the key to future profits - which indeed they are. "If they had any interest in raising standards, they would be sharing their findings with the world and opening dialogue with the design and business community about how best to integrate techniques with standard processes," he said. The World Health Organisation estimates that there are around 600 million disabled people worldwide, which represents about 10% of the world's population. Of these, around 80% are believed to live in developing countries. The countries surveyed by Nomensa were Argentina, Australia, Brazil, Canada, Chile, China, France, Germany, India, Japan, Kenya, Mexico, Morocco, Russia, Singapore, South Africa, Spain, United Arab Emirates, United Kingdom and United States of America.

Yahoo shake-up to take on rivals BBC News
Yahoo has announced a restructuring drive, as it attempts to simplify its business and take on rival Google.
Yahoo is a major player on the internet
The US web giant said chief financial officer Susan Decker would lead a new advertising unit, positioning her as a possible future chief executive. Meanwhile, chief operating officer Daniel Rosensweig - a rival for the top job - will leave Yahoo in March. The shake-up at Yahoo's key advert and marketing units comes as the firm faces tougher competition on the internet.

Major force
The pioneering internet firm has struggled with the changing nature of website advertising, as firms chase younger customers on a growing number of social networking sites including MySpace and Facebook.
QUOTE("Jordan Rohan @ RBC Capital Markets")
This is just the beginning of what Yahoo needs to do - it may take all of 2007
Yahoo lost out to internet search rival Google earlier this year, which snapped up video-sharing firm YouTube for $1.65bn. The firm's latest quarterly results also saw it report a 37% drop in quarterly profit, sparking alarm among senior managers headed by current chief executive Terry Semel. But Yahoo remains a major force on the internet, and it believes the reorganisation will help it continue to grow. The company will be split into two key divisions - Audiences, which will control search, media and communication products and services; and Advertisers and Publishers, which will focus on ads aimed at users. "This is just the beginning of what Yahoo needs to do," said Jordan Rohan, an analyst with RBC Capital Markets. "It may take all of 2007. Change like this is evolutionary, not revolutionary. The new division heads will need time to grasp the enormity of the task at hand."

First flight for future fighter BBC News
The world's most expensive military project, the F-35 Joint Strike Fighter, is expected to take to the skies for its maiden test flight next week.
US defence giant Lockheed Martin is heading the project
The $276.5bn Anglo-American stealth fighter project will supply the armed forces of the US, Britain and several other countries. The US will account for the lion's share of the Lockheed Martin-designed plane, with 2,400 in service by 2027. Britain's BAE Systems is one of the key players in the aircraft's development. BAE has pumped $2bn into the project, with the UK expected to take delivery of 138 fighters.

Supersonic
Marine Brigadier General David Heinz said the maiden test flight of the Joint Strike Fighter would take place in Fort Worth, Texas.
Britain's BAE systems is a key player in the project
"I am optimistic that we will see the airplane fly as early as Monday," said Brig Gen Heinz, the Pentagon programme office's deputy director. He said the planned 60-minute test flight of the F-35 would go ahead on the day, weather conditions permitting. The single-engine, supersonic fighter, each of which will cost in the region of $45m, is designed to replace the US's aging F-16s and F/A-18 Hornets. In Britain, the F-35 will be used by the Royal Air Force, while a separate - more expensive - model designed to land on aircraft carriers is scheduled to be deployed by the Royal Navy. A jump-jet version of the Joint Strike Fighter is being developed for the US Marine Corps. Along with the US and Britain, the F-35 is being co-financed by Australia, Canada, Denmark, Italy, the Netherlands, Norway and Turkey. Despite heavy cost overruns, Brig Gen Heinz said he expected all the contributing partners to place orders for the jet, taking combined purchases for the F-35 to 3,100 aircraft. In August, UK jet engine firm Rolls-Royce won a £1.3bn deal to develop a second engine for the fighter.

Mobiles 'cleared' of cancer risk BBC News
Long or short-term mobile phone use is not associated with increased risk of cancer, a major study has found. Mobile phone antennas emit electromagnetic fields that can penetrate the human brain. But a Danish team found no evidence that this was linked to an increased risk of tumours in the head or neck as had been feared. The study, of more than 420,000 mobile phone users, appears in the Journal of the National Cancer Institute. The researchers, from the Danish Institute of Cancer Epidemiology in Copenhagen, looked at data on people who had been using mobile phones from as far back as 1982. More than 56,000 had been using a mobile phone for at least 10 years. They found no evidence to suggest users had a higher risk of tumours in the brain, eye, or salivary gland, or leukaemia. Professor Tricia McKinney, Centre for Epidemiology and Biostatistics, University of Leeds, said: "The results of this Danish cohort study are important as they have analysed data from mobile phone company records and do not rely on users remembering for up to 10 years in the past how often they used their phone. "The large numbers of subscribers in the study mean we can have some confidence in the results that have not linked mobile phone use to a risk of any cancer, including brain tumours."

Similar findings
The study follows a report published earlier this year by the Institute of Cancer Research, which concluded that mobile phone use was not associated with a greater risk of brain cancer. An independent group for the UK government, led by Sir William Stewart, that looked into the safety of mobile phones in the late 1990s also concluded mobile phones did not appear to harm health. However, expert advice is still to limit mobile phone use among young people as a precautionary measure, as their head and nervous systems may still be developing. And the government currently advises mobile phone users to keep their call times short. There are more than one billion mobile phone users worldwide.

Planet-detector nears its launch Science reporter, BBC News
The hunt for Earth-like planets is to be stepped-up as a new mission prepares for launch.
Corot will be launched just after Christmas (Image: Cnes)
Corot will be the first spacecraft capable of detecting rocky planets just a few times bigger than Earth that are orbiting neighbouring stars. It will also uncover information on the stars themselves, determining their mass, age and chemical composition. The mission, led by the French space agency Cnes, is due to launch on the 26 or 27 December. Thien Lam Trong, Corot Project Manager from Cnes, said: "Man has been thinking about other worlds since the beginning of astronomy. Corot will help us to understand whether Earth-like exoplanets are a reality or dream."

Dimming lights
The 650kg (1,400lb) satellite will be launched on the Soyuz-2-1b vehicle from the Baikonur Cosmodrome, Kazakhstan, into a polar orbit 827km (514 miles) above the Earth. Corot carries a 27cm (11in) telescope and a four-charge-coupled-device (CCD) camera, sensitive to tiny changes in the brightness of stars. "There are two main science objectives for this mission," said Ian Roxburgh, professor of astronomy at Queen Mary, University of London, who is the European Space Agency (Esa) scientist on Corot. Esa is a partner on Corot along with Austria, Spain, Germany, Belgium and Brazil. And one of these, he said, would be to monitor about 60,000 stars to find some of the planets orbiting them. "As a planet comes inbetween us, the observer, and the star, it goes across the front of the star and blocks out some of the light - this is called a transit, like the transit of Venus. "So we will be measuring the light from the stars, looking for decreases in brightness to detect if a planet is in orbit."
The spacecraft will detect planets in transit across the stars (Image: Cnes)
Over a period of about 2.5 years, the satellite will focus on five to six different areas of the sky, each time for a duration of about 150 days. Every 512 seconds, it will measure the brightness of approximately 10,000 stars captured by the onboard camera, which employs the same technology as everyday digital cameras, allowing minute changes in the intensity of their light to be detected. By measuring these contrasts, the scientists will be able to detect many different types of planets, from huge gaseous ones to small rocky planets. But it is the smaller planets that are of most interest to the team. While larger planets can be detected from the ground using a variety of techniques, explained Professor Roxburgh, planets nearing Earth's size cannot. Corot will be the first spacecraft capable of finding them, he said. "We should be able to get down to planets about twice as big as Earth." The team are expecting to find between 10-40 of these smaller planets and tens of larger gaseous ones in each of the star fields the team observes.

Star variety
The other part of the mission is to find out more about the stars themselves. By observing the subtle changes in light created as sound waves ripple through the star - a technique called asteroseismology (similar to seismology, which uses earthquake waves) - the team will be able to find out more about the body's interior and determine its mass, age and chemical composition. Professor Roxburgh said the team aimed to find out more about 60 of the brightest stars in the area of sky they are observing.

This, he said, would add to data currently being collected by another Canadian mission, called MOST, which is using a 15cm (6in) telescope aboard a satellite to study the sky. "Corot will cover a large selection of stars - this is important because you need a good sample of different sorts of stars, with different properties and different ages, in order to understand stellar evolution." With the data it gains from the mission, particularly relating to Earth-like planets, the team hopes to inform future space research. In the second decade of this century, Esa plans to launch the Darwin flotilla - a fleet of four or five spacecraft that will hunt for Earth-like planets around other stars and analyse their atmospheres for signs of extra-terrestrial life. While US space agency Nasa is to launch a Terrestrial Planet Finder (TPF) mission which will also aim to locate Earth-like worlds. Professor Roxburgh told the BBC News website: "Corot is a pioneer as far as planets are concerned. "It will enable us to get knowledge of the sorts of stars that have planets and that sort of information will be needed for the next generation of missions searching for signs of habitable planets."

Microsoft debuts book search tool BBC News
Anyone wanting to view an obscure tome from the vaults of the British Library will be able to look for it online from Thursday.
Microsoft is releasing its Live Search Books, a rival to Google's Book Search, in test, or beta, version in the US. The digital archive will include books from the collections of the British Library, the University of California and the University of Toronto. Books from three other institutions will be added in January 2007.

Search full text
All the books currently included in the project will be non-copyrighted but later it will also add copyrighted work that publishers have given permission to include in the project. "We feel very strongly about copyright. We don't do any mass scanning of in-copyright works," said Danielle Tiedt, the general manager of Live Search Selection for Microsoft. Initially the database of available books will be searchable from the book search engine's home page or as a category on the main Windows Live Search page. Later Microsoft plans to integrate all the books scanned into its general search engine. "What we are focusing more of our efforts on for live searching is integrating all of those content types together to give you the most relevant results. If, for example, it's a search on historical content, chance are the most authoritative content may be found in a books search," said Ms Tiedt. The system has a feature called "search inside a book" which will allow users to search the full text of books. "We've focused on making the search experience really impactful...People will have full access to all of the text," said Ms Tiedt. A separate global digital library plan by Google is also under way. The search giant is spending $200m (£110m) to create a digital archive of millions of books from four top US libraries. It is also digitising out-of-copyright books from the UK's Oxford University. In contrast to Microsoft Google's plans include adding both copyright and non-copyright books from participating institutions. Although only copyrighted books will be available to view in full text, its project has come under fire from the Association of American Publishers and the Authors Guild

Australia overturns cloning ban BBC News
Australia's parliament has lifted a ban on cloning human embryos for stem cell research, despite opposition from the prime minister and other party leaders. The House of Representatives approved the legislation by a vote of 82 to 62. It was passed by the Senate last month. It will clear the way for researchers to engage in therapeutic cloning. Scientists hope stem cell research will lead to treatments for conditions including Parkinson's and Alzheimer's, as well as spinal cord injuries. Members of parliament were permitted a conscience vote - meaning they were not bound by their party's policy - following heated debate. Despite strong support for the bill, both Prime Minister John Howard and new Labour leader Kevin Rudd made impassioned speeches against repealing the ban. "I think what we're talking about here is a moral absolute and that is why I cannot support the legislation," Mr Howard said. "I don't think the science has shifted enough to warrant the parliament changing its view, and for that reason I'm going to vote against the bill."

Future treatment
Australia's first laws on stem cell research were passed in 2002, allowing scientists to extract stem cells from embryos left over from IVF programmes, but banning cell cloning. The new legislation will allow therapeutic cloning - the splicing of skin cells with eggs to produce an embryo from which stem cells (capable of forming human tissues) can be taken. The cloned embryos cannot be implanted in a womb and must be destroyed within 14 days. The senator who drafted the bill, former Health Minister Kay Patterson, said the law would be introduced in six months after health and science authorities drafted guidelines for egg donation and research licences. "This work's being done in Sweden, England, the United States, in Japan... I didn't see how we could accept any treatment derived from this in the future if we didn't allow the research here in Australia," Ms Patterson said. She said she believed the legislation could be made more liberal and that it must be reviewed after three years.

Commission calls for cuts in cod BBC News
The European Commission has called for cuts in catches of cod, herring, plaice, whiting and haddock for 2007. Announcing its annual recommendations to European ministers, the commission said there had been no significant improvement in cod stocks. Conservation groups say the commission's proposed 25% cut in cod catch would make little impact. In October, the EU's scientific advisory body recommended that no cod or anchovy should be caught next year. The International Council for the Exploration of the Sea (Ices) has made this recommendation on cod four years running, but each year the commission has recommended more modest cuts which have been made still more modest by European ministers. This year's final decision is anticipated on 19 December.

'Modest' target
European Fisheries Commissioner Joe Borg admitted that fishing pressure was still too great on some stocks, but said others were showing signs of recovery. "We must take heart from the positive signs observed in some of the stocks subject to long-term [recovery] plans," he told reporters at a Brussels news conference. Stocks showing signs of recovery include populations of hake around northern Europe and some populations of mackerel, for which the commission recommends increases in the annual catch. But these are the exception. The commission wants quotas cut for cod, herring, plaice, pollack, skate, sole, whiting, ling, Norway lobster, tusk, and most haddock populations. In November, a vast global study of fisheries projected that without major changes in fishing behaviour there would be nothing left to fish from the world's seas by 2050. Environmental groups have condemned what they describe as "modest" recommendations from the European Commission. WWF's Fisheries Policy Officer Tom Pickerell said: "Making continued adjustments to cod quotas alone will frankly not help cod populations recover, or enable fishermen to make long-term plans." The organisation advocates expanding the use of selective fishing gear, placing observers on boats, and setting limits on bycatch (catching species other than the target).

Water flowed 'recently' on Mars BBC News
Nasa says it has found "compelling" evidence that liquid water flowed recently on the surface of Mars.
Gullies like this could have been cut by water, Nasa says
The finding adds further weight to the idea that Mars might harbour the right conditions for life. The appearance of gullies, revealed in orbital images from a Nasa probe, suggests that water could have flowed on the surface in the last few years. But some scientists think these fresh gullies could also have been cut by liquid carbon dioxide (CO2). The latest research emerged when Nasa's Mars Global Surveyor (MGS) spacecraft spotted gullies and trenches that scientists believed were geologically young and carved by fast-moving water coursing down cliffs and steep crater walls. Scientists at the San Diego-based Malin Space Science Systems, who operate a camera aboard MGS decided to retake photos of thousands of gullies in search of evidence for recent water activity.
QUOTE("Phil Christensen - Arizona State University")
Two gullies that were originally photographed in 1999 and 2001, and imaged again in 2004 and 2005, showed changes consistent with water flowing down the crater walls, according to the study. In both cases, scientists found bright, light-coloured deposits in the gullies that were not present in the original photos. They concluded that the deposits - possibly mud, salt or frost - were left there when water recently cascaded through the channels. Other scientists think it possible that gullies like this were caused not by water but by liquid carbon dioxide. One of the reasons for favouring CO2 was that computer models of the Martian crust indicated water could exist only at depths of several kilometres. Liquid carbon dioxide, on the other hand, could persist much nearer the surface where temperatures can drop as low as -107C.

Prospects for life
Oded Aharonson, an assistant professor of planetary science at the California Institute of Technology (Caltech) said that while the interpretation of recent water activity on Mars was "compelling," it was just one possible explanation. Aharonson said further study was needed to determine whether the deposits could have been left there by the flow of dust rather than water. Deciding what was responsible for the features is a pressing question that has important consequences for the likelihood of life on Mars. Scientists have proposed that reservoirs of liquid water could exist beneath the Martian surface, providing a habitat for microbial life. "This underscores the importance of searching for life on Mars, either present or past," said Bruce Jakosky, an astrobiologist at the University of Colorado at Boulder, who had no role in the study. "It's one more reason to think that life could be there." Mars Global Surveyor abruptly lost radio contact with Earth last month. Attempts to locate the spacecraft, which has mapped the Red Planet since 1996, have failed, and scientists fear it is lost. Nasa's Mars rovers, which landed in 2004, have sent scientists back equally strong evidence that liquid water flowed on the surface in ancient times, based on observations of alterations in ancient rocks. "We're now realising Mars is more active than we previously thought, and that the mid-latitude section seems to be where all the action is," said Arizona State University scientist Phil Christensen, who was not part of the current research. Details of the work appear in the journal Science.

Study backs Libya HIV case medics BBC News
Scientists have cast doubt on charges that five Bulgarian nurses and a Palestinian doctor deliberately infected Libyan children with HIV. The medics could face the death penalty if found guilty by a court in Tripoli later this month. An international team analysed samples taken from the infected patients. Writing in Nature, they said their work showed the HIV subtype involved began infecting patients in Libya well before the medical workers arrived in 1998. An initial trial condemned the medics to death in 2004, but the Libyan Supreme Court overturned the verdicts, and ordered a retrial. The defendants are accused of knowingly infecting more than 400 children with HIV in the eastern town of Benghazi. The medics say that they were tortured into giving false confessions. The first trial lasted almost six years, and the medics have been in jail since 1999. They say the children were infected through poor hygiene - and a body of scientific work supports their claims.

History of outbreak
The researchers worked on blood samples collected by a network of European clinical research centres that are involved in treating the infected children. By analysing mutations in the genetic material of the HIV virus found in the samples they were able to reconstruct the history of the outbreak. Lead researcher Dr Tulio de Oliveira, from Oxford University, said: "All the lines of scientific evidence point in the same direction, towards a long standing infection control problem at the hospital, dating back to the mid 1990s or earlier." Dr Thomas Leitner, of Los Alamos National Laboratory, has provided forensic evidence in many HIV cases. Writing in Nature, he said the latest research was "compelling evidence that the outbreak had started before the accused could have started it." There has been mounting international pressure on Libya to hear independent scientific evidence. International experts say the scientific report used in the trial was nothing but 'conjecture' and 'supposition'. Last month 114 Nobel Laureates wrote an open letter to Colonel Gaddafi urging the appropriate authorities to hear independent science-based evidence, and reaffirming the need for a fair trial.

France launches world TV channel BBC News
France's first international news channel has been launched into competition with BBC World and CNN.
President Chirac has given his personal backing to the project
France 24 was unveiled on the internet at on Wednesday evening, and will launch on satellite and cable TV 24 hours later. The channel has the backing of French President Jacques Chirac, who despaired at the lack of an outlet for French views in the run up to war in Iraq. But some critics have complained it has insufficient funding to compete. The network has a budget of 86m euros a year. That compares with 900m euros for CNN.
QUOTE("News 'a la francaise'")
France is joining what Chirac calls the 'global battle of images'
France 24's 170 journalists will be spread across two parallel services in French and English. Later it will add Spanish and Arabic broadcasts. Some experts have said this will leave it stretched. It will be able to call on correspondents from private channel TF1 and state-owned France Televisions channels, which will jointly run France 24, but there have been concerns that it is not clear who will take priority.

'Through French eyes'
The fanfare leading up to the launch included full-page advertisements in French newspapers Le Parisien and Le Figaro on Wednesday, alongside the channel's slogan: "All the news you're not supposed to know." The running order was said to include an interview with President Chirac. The president visited the station's newsroom ahead of the launch. France 24's journalists have signed a mission statement "to cover international news with a French perspective... and to carry the values of France throughout the world". But the channel insists it is independent and will not just follow the government line. "Our mission is to cover worldwide news with French eyes," said the channel's head, Alain de Pouzilhac.

Wii shortages frustrating gamers BBC News
Shortages of Nintendo Wii consoles around Europe have left some gamers who pre-ordered the new machine frustrated.
Some gamers enjoyed a Wii success story
Nintendo, which has already launched the machine in the US and Japan, said it expected to sell out of Wiis on the first day of sales. More than four million Wiis will be shipped globally this year, and 50,000 were sold in the UK in 12 hours. BBC News has been e-mailed by gamers disappointed that pre-orders for the machine have not been fulfilled. More than 1,200 Wiis have gone on sale on online auction site eBay in the UK within hours of the launch. The highest price for a console so far has been £500. Simon Ball from Wales e-mailed the BBC News website to say he had failed to receive his ordered Wii.
A clickable guide to the Wii
He said: "I pre-ordered the Nintendo Wii from Play.com on 15 September along with some software. "I have been informed today that it is unlikely my order will be fulfilled before Christmas. Incredibly they have dispatched the game we ordered to accompany the console."

'Not shipped enough'
Claire Inglesby from Liverpool wrote: "I pre-ordered the console in November from Woolworths website for my son's Christmas present. "I received an e-mail today informing me that as Nintendo had not shipped enough I might not receive my order.
Many shops opened at midnight for the launch
"So the fact that I had the foresight to pre-order and not disappoint my son means very little as they obviously expect me to camp outside Woolworths for days on end." David Yarnton, general manager, Nintendo UK, said: "We are doing everything we can do to meet demand throughout Christmas and the New Year period." A spokesman for Woolworths said there were problems getting stock from Nintendo. The UK chain has said it expects to fulfil all pre-orders for the machine by next Tuesday or Wednesday. He said: "Demand has far outstripped supply and we are delighted to have been able to secure a significant amount of consoles for our customers before Christmas." Woolworths were not able to confirm if they would receive any more stock once pre-orders had been met. Currys, PC World and Dixons have said they will deal with outstanding pre-orders in "strict chronological order".
Nintendo has warned people to be careful with the Wiimote
In a statement from the retail group, it said: "When we reached the point in the pre-ordering process when demand exceeded anticipated supply, we made it clear to any customers choosing to join the list after that date there were no guarantees that we would be able to fulfil their orders prior to Christmas." Rob Lowe, UK product manager for Wii, said: "There is a good chance it will sell out on Friday. "Judging by the feedback we have had from the retailers I would say you would be lucky to get one on Saturday," he said. Response to the Nintendo Wii's release has been very positive among consumers and journalists. The console costs £179 and includes a motion-sensitive controller shaped like a remote control. The so-called Wiimote can be jabbed, swung, waved and turned to imitate a range of real-life motions that are represented on screen. Nintendo hopes that simplifying the control system will make games consoles less intimidating to non-gamers and more accessible and immersive for hardened players.

I pre-ordered my Wii from an online store a few months ago. A friend of mine had ordered his before me, from a different online store, and was advised recently that he wouldn't be getting one on release day. Thankfully the company I ordered with seems to have more stock. Mine has been despatched and I'm waiting for the delivery man to arrive with it any minute now!

Pre-ordered a Wii from Curry's. Went to pick it up to find the store covered in posters telling me that they (as in all Curry's shops) had received nothing from Nintendo and that their allocation had been reallocated to another store. They offered me a refund or a wait until January. Took the refund.
CJ Anderson, Biggin Hill Kent

I have pre-booked a Wii from Oxford Street HMV, but have been told they only got 51 units to satisfy the pre-orders, but were also told 200 people who haven't pre-ordered can wait outside Oxford Street store and queue. A lot of students and people who don't have a full time job are laughing in the queue and there are so many on ebay for sale for nearly double the price. Why have Nintendo done this? People are making money out of these units by themselves. I hope I get mine before Christmas otherwise I will cancel my order. The bigger the company it seems the less they care about their loyal fans...who happen to have a life outside video games and can't queue up for two days.
Tim Warren, London

Having not pre-ordered a machine I was highly doubting being able to pick one up before Christmas. I took a chance and headed down to the local 24-hour Tesco. I arrived there at 7pm and was 18th in the queue, with a total of 28 machines and a limited number of games available. My biggest thanks go to the staff at Tescos in Wath upon Dearne. They provided seating, hot drinks, and it was easily the most organised, efficient and top class service I have received in a long time. I left the store at 12:01 with a Wii and Wii sports, extra remote and Wii Play, for £210 all in. Top stuff.
Lee Hawksworth, Rotherham, UK

I pre-ordered with Game and successful collected it at midnight. I was just going to pick it up this lunchtime but the manager warned they "may" be short in accessories and games so I went down just in case. Got everything we needed and it is currently sitting at home waiting to be opened this evening when a party of invited people arrives. Very excited indeed.
Claire, Glasgow

I managed to pick one up without pre-ordering. A local shop had five non-pre-order consoles in stock; I arrived 30 minutes before it opened and was first in the queue. The smaller retailers are a Godsend!
Jamie Cole, Newcastle upon Tyne

I pre-ordered a Wii from Woolworths for delivery to my local store on 7th November. I was told it was despatched on 2nd December, and then nothing.... The store don't know, the customer service don't know. They have my money and they have supposedly sent it to the store, but it has taken six days and no joy. I am not quite sure where they are sending it from - but six days in this modern age to deliver a parcel in the UK is madness.
Mat Robinson, Bishops Stortford, Herts

My boyfriend pre-ordered his Wii online more that a month ago, and it never arrived today. He's very disappointed as he took the day off just to play it. It might come tomorrow, but the weekend is ruined already.
Amanda Harrigan, Dunfermline, Fife

I pre-ordered the console in November from Woolworths website, for my son's Christmas present, I received an email today informing me that as Nintendo had not shipped enough I might not receive my order. And yet, according to your news article Woolworths are preparing for a busy time ahead expecting today to 'be busiest day of the year' - charming! So the fact that I had the foresight to pre-order and not disappoint my son means very little as they obviously expect me to camp outside Woolworths for days on end. I will indeed remember to book extra time off work next year in order to do so!
Claire Inglesby, Liverpool

I ordered mine with Argos a while ago and was told that I will receive it on release date. On 5 December I spoke to Argos and again it was on its way, so far down the order on its way that I wasn't allowed to change the address it was to be delivered to but on 6 Dec I received a call to advise that they don't have enough. Now that's service for you. Merry Christmas from Argos.

Landmark EU chemical law passed BBC News
The European Parliament has backed a deal, reached with EU governments, on wide-ranging legislation to control the use of toxic chemicals in industry.
Industry and environmentalists have battled over the rules
The law is designed to make firms prove the thousands of chemicals they use in products from cars to clothes are safe. It comes after years of wrangling between firms keen to avoid more red tape and environmentalists seeking to cut the use of hazardous pollutants. EU nations will have until 2018 to implement the new rules.

Safety standards
Reach has been described as the most important piece of EU legislation for 20 years.
QUOTE("REACH IN NUMBERS")
  • 1,000 pages of text
  • 30,000 chemicals to be registered over 11 years
  • At least one million more animal tests
  • Billions of euros saved in healthcare costs
  • Q&A: Reach chemicals law
It puts the onus on business rather than public authorities to test chemicals for safety - including the thousands of chemicals that have been used for years without proper understanding of their effect on health or the environment. It is also meant to encourage the replacement of hazardous chemicals with safer ones, and to spur innovation. However, environmentalists had always hoped the law would go further than it did in its final version - and industry groups still say it went too far. "This deal is an early Christmas present for the chemicals industry, rewarding it for its intense and underhand lobbying campaign," said Green MEP Caroline Lucas. Alain Perroy, director general of the European Chemical Industry Council (Cefic) said his members regretted the "unnecessary requirements" introduced for authorisation of chemicals.

New agency
Environment Commissioner Stavros Dimas said it would "increase our knowledge about chemicals, enhance safety, and spur innovation, while encouraging substitution of highly dangerous chemicals by safer ones".
QUOTE("BEUC director Jim Murray")
What has been agreed must now be implemented properly and we will actively monitor the situation
Europe's main consumer group BEUC said the adoption of the law was not the end of the story. "What has been agreed must now be implemented properly and we will actively monitor the situation," warned BEUC director Jim Murray. He pointed out that the deal still allows some cancer-causing substances and other poisonous chemicals to be used in consumer products, even when safer substances exist, as long as they have been subject to "adequate" control. "The only adequate form of control for such substances is substitution when possible," he said. The system for registration, evaluation and authorisation of chemicals (Reach) demands that firms provide lists of the chemicals they use and specify any possible risks. A newly-established agency in Finland will oversee the way the firms assess chemicals for safety. The register will initially focus on the most toxic chemicals and those produced in the largest quantity.

Issues unresolved
Manufacturers will have to come up with plans to replace the most hazardous chemicals, but they will not be banned outright as environmentalists had hoped. While the EU said the deal improved the safety standard of chemicals, green lobbyists were angered by what they saw as the EU bowing to industry pressure. Conservation body the WWF said the final text of Reach "was not the complete disaster that it would have been if the chemical industry lobby had succeeded in all their wrecking tactics" but said it left a number of substantial problems unsolved. It also warned that the deal would continue to allow potentially harmful chemicals into the environment.

'Right advice'
After the legislation was passed the UK's Federation of Small Businesses (FSB) called on its government to help small firms. "This regulation will affect small businesses that manufacture or import chemicals in the EU as well as those using chemical preparations in their industrial or commercial activities," it said. It said that the cost of complying with the new rules would hit small firms "especially hard" because they were "least able to absorb costs or pass them on to their customers, unlike larger businesses". John Holbrow of the FSB added: "Civil servants must bear in mind the thousands of jobs across the business spectrum that depend on Reach being implemented well. "With the right advice small firms can do their bit without being left exposed to prosecution due to their understandable lack of resources and specialised knowledge." And the CBI warned: "An overly bureaucratic implementation of the regulations could yet undo the benefits of today's sensible compromise and make REACH unworkable."

Mountain range spotted on Titan Science reporter, BBC News, San Francisco
The Cassini spacecraft has spied the tallest mountains yet seen on Titan, Saturn's major moon.
Titan's Sierras are the biggest mountains yet seen on the moon
The range is about 150km long (93 miles), 30km (19 miles) wide and about 1.5km (nearly a mile) high. The feature was identified by the probe on a recent pass, using a combination of radar and infrared data. Dr Bob Brown, one of the scientists behind the discovery, said it reminded him of the Sierra Nevada mountains in the western US. "One could call them Titan's Sierras," the University of Arizona-Tucson researcher added. The mountains lie south of the equator. Scientists told the American Geophysical Union (AGU) Fall Meeting that the range was probably as hard as rock, but made of icy materials. The mountains appear to be coated with layers of organic, or carbon-rich, material. This could be methane "snow".

Impact story
Titan is smothered in a thick photochemical haze, so Cassini must use instruments other than its optical camera system to see features such as these mountains. Dr Brown, who leads Cassini's Visual and Infrared Mapping Spectrometer (Vims) team, said a theory was now emerging to explain how the range formed.
QUOTE("Dr Rosaly Lopes - Nasa JPL")
You can think of Titan as the Earth in deep freeze
It was likely they grew as material welled up from below to fill the gaps opened when tectonic plates pulled apart, he explained. This is similar to the way mid-ocean ridges are formed on Earth today. Dr Brown said the mountains were close to a circular feature which might be an ancient impact basin. He speculated that it was possible a space collision in Titan's past had kicked off the whole process. "The energy released in the impact was probably large enough for the impactor to punch through the crust of Titan which then caused tectonic disruption in the area, and that these [mountains] occurred some time afterwards. "If there is anything to this idea, if this is an impact basin, we ought to see something exactly opposite in the geology on the other side of Titan at what we call the antipode; and we haven't seen that yet."

Like Earth
Close to the mountains, Cassini's instruments also detect clouds. It is probable these are forming when the atmosphere is pushed over the elevated region by winds. The spacecraft's flyby on 25 October has obtained a wealth of new data. As well as the mountains and clouds, the probe saw more detail in the great dune fields that cover the world and spotted what appears to be an icy volcanic flow.
Cassini has been investigating Saturn and its moons since 2004
Scientists are fascinated by Titan because its chemistry may tell them something about the early Earth. From the few impact craters seen on the surface, scientists know it must be a very active world. There are channels that are probably being carved by liquid methane; it has volcanoes that spew ices; winds are eroding features and depositing material in distant locations. "You can think of Titan as the Earth in deep freeze," said Dr Rosaly Lopes, Cassini radar team member at the US space agency's Jet Propulsion Laboratory. "It has a lot of the geological processes that Earth has. In fact, it is more Earth-like than anywhere else in the Solar System. But the surface is very cold; it's about minus 178C."

Becoming clearer
British scientist Professor John Zarnecki was a principal investigator on the Huygens lander which Cassini put on Titan in January 2005. He said the moon continued to amaze. "It is incredible to think that all those kilometres away there is a moon which contains so many similar geographical features to those found here on Earth. "Huygens gave us a panoramic snapshot of the surface of Titan which we continue to anaylse. When coupled with the results from Cassini's flybys of Titan, we are really beginning to build up a detailed picture of the make-up of this intriguing moon." Cassini-Huygens entered into orbit around Saturn on 1 July 2004. The mission is a co-operative project of Nasa, the European Space Agency (Esa) and the Italian Space Agency (Asi).

You're on the cover of Time! Hindu, India
(PTI): Time magazine has tipped its cap in its latest issue to a person who is the driving force behind the present information age. You. The magazine's 'Person of the Year' issue, to be released today, features on its cover a mirror in a computer screen. Recognizing the power that individuals enjoy through blogs and sites like YouTube and MySpace, which allow them to air their opinion, Time magazine has chosen 'You' as the person of year over Iranian President Mahmoud Ahmadinejad, North Korea's Kim Jong II and former US Secretary of Defense Ronald Rumsfled who hogged headlines throughout the year. To be sure, Time says, there are individuals we could blame for many painful an disturbing things that happened during the year. The conflict in Iraq only got bloodier and more entrenched. A vicious skirmish erupted between Israel and Lebanon. "A war dragged on in Sudan. A 'tin-pot' dictator in North Korea got the Bomb and the President of Iran wants to go nuclear too. Meanwhile, nobody fixed global warming, and Sony didn't make enough PlayStations," it said. But looking through a different lens, it points out, "you'll see another story," one that isn't about conflict or great men. It's a story about community and collaboration on a scale never seen before. It's about the cosmic compendium of knowledge Wikipedia and the million-channel people's network YouTube and the online metropolis MySpace. "You. Me. Everyone. Everyone is who is transforming the information age by creating and consuming content," Richard Stengel, the magazine's managing editor told CNN's Soledad O'Brien. "It's about the many wresting power from the few and helping one another for nothing and how that will not only change the world, but also change the way the world changes." "You know, I felt in a very profound way something in the world change this year, that there was an ebbing of power from the few to the many, and big media companies like ours were, in fact, not in control anymore. It's a great new digital democracy," Stengel said. The tool that makes it possible, Time says, is the World Wide Web. Not the Web that Tim Berners-Lee hacked together (15 years ago, according to Wikipedia) as a way for scientists to share research. It's not even the overhyped dotcom Web of the late 1990s. The new Web is a very different thing. It's a tool for bringing together the small contributions of millions of people and making them matter. Silicon Valley consultants call it Web 2.0, as if it were a new version of some old software. But it's really a revolution, it stresses. "And we are so ready for it. We're ready to balance our diet of predigested news with raw feeds from Baghdad and Boston and Beijing. You can learn more about how Americans live just by looking at the backgrounds of YouTube videos - those rumpled bedrooms and toy-strewn basement rec rooms - than you could from 1,000 hours of network television," it says. But "we didn't just watch, we also worked. Like crazy. We made Facebook profiles and Second Life avatars and reviewed books at Amazon and recorded podcasts. We blogged about our candidates losing and wrote songs about getting dumped. We camcordered bombing runs and built open-source software. America, the magazine says, loves its solitary geniuses its Einsteins, its Edisons, its Jobsesy but those lonely dreamers may have to learn to play with others. Car companies are running open design contests. Reuters is carrying blog postings alongside its regular news feed. Microsoft is working overtime to fend off user-created Linux, it points out. "We're looking at an explosion of productivity and innovation, and it's just getting started, as millions of minds that would otherwise have drowned in obscurity get backhauled into the global intellectual economy," the magazine says. Who are these people? It asks and replies, the answer is you. "And for seizing the reins of the global media, for founding and framing the new digital democracy, for working for nothing and beating the pros at their own game, TIME's Person of the Year for 2006 is you." Sure, it's a mistake to romanticize all this any more than is strictly necessary, Time says. Web 2.0 harnesses the stupidity of crowds as well as its wisdom. Some of the comments on YouTube make you weep for the future of humanity just for the spelling alone, never mind the obscenity and the naked hatred. But that's what makes all this interesting. Web 2.0 is a massive social experiment, and like any experiment worth trying, it could fail. There's no road map for how an organism that's not a bacterium lives and works together on this planet in numbers in excess of 6 billion, the magazine concedes. But it says 2006 gave us some ideas. "This is an opportunity to build a new kind of international understanding, not politician to politician, great man to great man, but citizen to citizen, person to person. It's a chance for people to look at a computer screen and really, genuinely wonder who's out there looking back at them. Go on. Tell us you're not just a little bit curious.

2006 may be the year of 'you,' but 2007 may be the year to get over it USA Today
Looking back on 2006, there's no question that "user-generated" was THE tech buzzword of the year. Much of that buzz centered on user-generated content, which includes music, videos, blogs and MySpace pages created and posted on websites by millions of "users" — known as "amateurs" in a bygone, less politically correct era. Some of this content is fascinating, such as the video that mixes clever editing of Star Trek footage with a Nine Inch Nails song and makes the case that Spock and Kirk were actually lovers. (NOTE: The song and the video may be objectionable to some.)

Much of it, however, is dreadful.
Google's purchase of YouTube in October for $1.7 billion became the signal event of the user-generated content boom. It had me reminiscing about other notable zeniths, such as the Japanese buying Rockefeller Center in 1989. As the ultimate capper, Time magazine has anointed "you" as its Person of the Year in honor of user-generated stuff. This will probably stand the test of time as well as 1988's pick, The Endangered Earth. That selection came with the prediction that the planet's woes had "jumpstarted a new era of environmental activism." And then the Hummer was born. Interestingly, Time's choice is getting mocked by bloggers — aka users. The magazine kind of shot itself in the foot. Managing Editor Rick Stengel wrote an explainer saying that he asked for public input about the Person of the Year. Suggestions flooded in for newsmakers such as Donald Rumsfeld, Al Gore and Sacha Baron Cohen. But apparently nobody suggested "you." So in the end, Time asked us for our input like a good New Media do-bee, then played its Old Media power card and decided on its own choice — proving that users aren't really that in charge, and thus probably not deserving of Person of the Year status. Anyway, here at the end of the year, "user-generated" seems to be ascending to a whole new level. We've got companies such as General Motors hyperventilating over user-generated advertising. GM is asking users — citizens, amateurs, whatever — for ideas for an ad it will produce. Doritos is running a contest: Submit your self-produced Doritos ad, and the best one will be aired during the Super Bowl in a slot costing $2 million. Perhaps an ad depicting Spock and Kirk sharing a bag of chips ... A couple of weeks ago, Sun Microsystems Chairman Scott McNealy enthusiastically told me about one of his favorite new projects, called Curriki. It's essentially using the Web to let people contribute to the creation of online textbooks for grades K-12. "I think it is potentially as powerful as the Google idea or the MySpace idea," McNealy says. New site Wize.com is a kind of user-generated Consumer Reports magazine. It scans the Web for millions of reviews posted by individuals on hundreds of sites, sorts and tallies them, and comes up with ratings. This is a twist known as the wisdom of crowds. This wisdom can tell us that if you want a waffle maker, you should get a Waring WMK300 Professional Belgian Waffle Maker. It costs about $80. Where will this trend go in the next year? Well, Amazon.com is enabling the creation of user-generated businesses. This is not entirely new. EBay's heart and soul is the thousands of small businesses started by eBay users. Amazon, though, is renting out everything it does, from website hosting to warehouse space. If someone wants to start a retailer called Just Car Deodorizers, he or she can hire Amazon to do everything but decide which deodorizers to sell. CEO Jeff Bezos believes this could fuel a new wave of microbusiness. Ultimately, there is Second Life — a user-generated virtual world on the Internet. The company set up the virtual land, but its residents have made everything else: buildings, shops, cars, articles of clothing. Second Life might become the hottest thing on the Web in 2007. Bands such as Duran Duran are giving concerts there. Politicians are considering campaigning in Second Life. Reuters opened a virtual news bureau. Second Life has a population of 2 million that's growing fast. "When (people) have the ability to be creative, we will be," says Second Life creator Philip Rosedale. "Everybody's at least a little bit creative."

Flavor of next week?
But is "user-generated" overhyped? Tech culture has a habit of going bonkers for the flavor of the week. There were moments when life was going to change completely because of: artificial intelligence, interactive TV, portals, community sites, social networking, blogs … Always, somewhere down the road, after the publicity surge, we realize that what actually came to pass was more evolutionary. User-generated stuff has been around forever — in garage bands, personal journals, community theater, county fairs. The Web sets it free in ways never before possible, and that's significant. No question it is affecting media, entertainment and other aspects of life. But it's not likely to turn the world completely upside down. The editors of Time, as they have accidentally shown, still have a role to play and will probably have jobs next year and the year after. By then, we'll be onto another Next Big Thing. I'll throw out one possibility — something that doesn't really even have an overarching buzzword yet. Some call it geo-presence. You might already know what presence is. If you use something like AIM or Skype, it's the ability to see that someone you know is also online. The next thing will let you also see where they are. Helio just came out with cellphones that can show where your buddies are on a map. The Wi-Fi network at the Massachusetts Institute of Technology has been set up so users can pinpoint their friends. Sounds cool to me. Will probably change the world. Bigger than The Beatles. Call the editors of Time. User-generated blah blah blah. That was so 2006.

Anti-Smoking Effort Jumps on Social Networking Sites Brandweek.com
The American Legacy Foundation's national smoking prevention campaign aimed at youth tackles social networking Web sites with the latest phase of the "Infect truth" campaign. Starting this week, materials like truth wallpaper, branded bumper stickers and even ads that can be affixed onto the backs of cockroaches (fake ones, of course) are available for downloading through MySpace, Hi5, Bebo, Piczo and Xanga. Teens also can grab "Infect truth" wallpaper and case covers for their Sony PlayStation consoles—the first time truth has produced creative for the portable gaming device. The combined reach of social networking sites exceeds 59 billion page views per month, and truth intends to tap into the viral magic of that medium with forward-to-a-friend technology. The initiative's tagline is "Knowledge is contagious: Infect truth." Content includes information about the consequences of tobacco industry marketing such as a birthday card with the sentiments: "I'm glad you're not one of the over 400,000 people who won't be celebrating their birthday this year, thanks to Big Tobacco's products." Teens can surreptitiously plant the card in store racks."With declining funds, truth seeks to put truth messages in nontraditional, easily accessible and effective mediums such as digital media," Joseph Martyak, ALF's evp-marketing, communications, and public policy, said in a written statement. "The tobacco industry spent more than $15.1 billion in 2003 marketing its products in the U.S. alone. We can never match that spending, so instead we stay ahead by being more cutting edge and going directly to teens in media and at places where they naturally gather." The effort also will be supported by new TV ads and print executions. A rotating sample of spots and static ads will appear on the MTV billboard in New York's Times Square through mid-February. Arnold Worldwide, Boston, and Crispin Porter + Bogusky, Miami are the agencies of record. Between 1999 and 2003, ALF had been funded by payments from Philip Morris, R.J. Reynolds Tobacco, Brown & Williamson and Lorillard. That arrangement was the result of the 1998 Master Settlement Agreement, which settled lawsuits from 46 states and five U.S. territories that were seeking reimbursement from cigarette makers of Medicaid payments issued to smokers. Those payments stopped thanks to an MSA provision that freed manufacturers from sending money to the foundation when their combined market share dipped below 99.05%. ALF since has been funding its annual operations and advertising budget through investment income from a $1 billion trust.

The Shrinking Long Tail - Top 10 Web Domains Increasing in Reach Rojo
Last week I was following the De-Portalization of the Internet thread, started by Fred Wilson and then extended by Keith Teare. I was struck by one observation in particular by Fred:
QUOTE("Fred")
"I don't have the data to prove it, but my guess is if you looked at the percent of all pageviews that are generated each month, a much smaller portion exist on the top 10 properties today than in 2000, at the height of the first Internet era."
Essentially Fred's theory is that the Long Tail of Interne<t content makes up a higher percentage of total Web page views today, than 6 years ago. I asked Web Analytics firm Compete if they could come up with some data to prove or disprove Fred's hypothesis. Compete kindly provided me with some great data, which in a nutshell disproves Fred's theory. According to Compete's data, the top 10 domains are not shrinking - but proportionally increasing.

Internet has grown by 77% in last 5 years
Looking first at the overall growth of the Internet, according to Compete's data the Internet has grown by 77% in the last five years to over 5 million unique domains. (Note: This count includes misspelled and unhosted domains people accidentally find themselves at).
Source: Compete
Top 10 account for larger % of total PV, not smaller
Contrary to Fred's theory and the larger theory of the Long Tail, the top internet properties are accounting for a larger percentage of total pageviews across the web. According to Compete, currently the Top 10 domains account for 40% of the total pageviews on the internet - a 29% increase over the last five years.
Source: Compete
Social Networks to blame
The driver of this Top Domain growth can be summed up in two words: "social networks". If you were to remove MySpace and Facebook from consideration in 2006 (also removing their pageviews from the total) Top Domains would only account for 33% of total pageviews - basically on par with 2001. The following chart shows the difference in top 10 domains over the past 5 years.
Source: Compete
Note on The Long Tail
The Long Tail is a theory that has been popularized over the past year by Wired editor Chris Anderson - with his book and blog of the same name. The easiest way to define The Long Tail is to present this graph (c/o Wikipedia):
The long tail is the part colored in yellow.
Summary
The usual disclaimers apply about Internet statistics - you would probably get different stats from comScore and Alexa. But the overall trends are of most interest here. It does appear that the top 10 web properties are claiming proportionally more page views in 2006 than in 2001. The impact of the Long Tail can still be felt strongly on the content creation side, on sites like MySpace and YouTube. So in one sense you could argue that The Long Tail has had an impact on the top 10 domains after all - in terms of who is creating the content. But the fact is that those properties are still owned and operated by big media (News Corp and Google in the above two cases). So in that respect, and according to Compete's stats, the top 10 domains have more reach now than 5 years ago.
Update: The Compete blog has further analysis.

Republican Aide Tries to Hire Hackers slashdot
"It seems as though a Republican Communications Director contacted Attrition.org, trying to hire hackers to improve his educational records. I don't know what is his dumbest move:
  • (a ) contacting Attrition in the first place,
  • (b ) using a real name Yahoo email address or
  • (c )speaking at length about what he needed?
Kudos to the Attrition crew for posting the whole email dialogue online! A sample from the conversation: 'Jericho: First, let's be clear. You are soliciting me to break the law and hack into a computer across state lines. That is a federal offense and multiple felonies. Obviously I can't trust anyone and everyone that mails such a request, you might be an FBI agent, right? So, I need three things to make this happen: 1. A picture of a squirrel or pigeon on your campus. One close-up, one with background that shows buildings, a sign, or something to indicate you are standing on the campus. 2. The information I mentioned so I can find the records once I get into the database. 3. Some idea of what I get for all my trouble.'"

Shuttle cleared for Earth return BBC News
The shuttle Discovery has been cleared to return to Earth, but poor weather over the Kennedy Space Center may force it to an alternative landing site. Nasa controllers have Edwards Air Force Base, in California, and White Sands Space Harbor, in New Mexico, on standby to receive the vehicle. If the rain and clouds lift at Kennedy, Discovery's first landing opportunity is at 2056 GMT (1556 local time). Nasa is prepared to delay the return to Saturday if needs be. "As we get closer, we'll have much more certainty on what we're really faced with," said Norman Knight, who will direct the landing. The shuttle has been on a 13-day mission to rewire the International Space Station (ISS). In addition, its crew fitted a connecting segment that will allow the platform's backbone to be extended further in future. They also delivered two tonnes of supplies; and dropped off one new resident, American Sunita Williams, and picked up a returning astronaut, German Thomas Reiter.

Future flights
Discovery needs to be on the ground on Saturday or it will run low on the fuel that powers its electrical systems. The shuttle would normally have had more time to make a landing but its astronauts made an unscheduled, extra spacewalk at the station to free a stuck solar array. Controllers will keep the vehicle in orbit until they see a weather opening at one of the three landing strips. White Sands was looking the most favourable location on Friday with strong crosswinds forecast for Edwards. During the 25 years of the shuttle programme, White Sands has been used only once, in 1982 (Kennedy has seen 63 landings; Edwards has had 50). Shuttle pilots use White Sands to practise landings in a simulator aircraft, but Nasa would prefer not to put the shuttle down there for real, if it can be avoided. After the last landing at the New Mexico desert location, the orbiter was covered in fine sand. It would also take longer to move the shuttle back to Kennedy for future flight preparation. The next construction mission to the ISS will be undertaken by the Atlantis shuttle in March. This will see a third set of solar arrays and batteries fitted to the station. May should see the maiden flight of a new re-supply vessel for the station. Known as the Automated Transfer Vehicle (ATV), it will be launched on an Ariane 5 rocket from the European spaceport at Kourou in French Guiana. Europe also has keen interest in Discovery's next mission scheduled for October. This mission will deliver the Columbus science module, Europe's biggest contribution to the ISS project.

Anti-Intellectual Arguments Against Anti-Intellectualism Are Always Such Fun! Institute for Ethics and Emerging Technologies
In a recent NYT Op-Ed Nicholas Kristof points out the frightening and lamentable facts that “40 percent of Americans believe in evolution, and only 13 percent know what a molecule is… One-fifth of Americans still believe that the Sun goes around the Earth, instead of the other way around. And only about half know that humans did not live at the same time as dinosaurs.” He rightly goes on to claim that this is “a symptom of something much deeper and more serious: a profound illiteracy about science and math as a whole.”

From this he goes on to make a frankly flabbergasting accusation: “The problem isn’t just inadequate science (and math) teaching in the schools, however. A larger problem is the arrogance of the liberal arts, the cultural snootiness of, of… well, of people like me—and probably you.” Just to be clear at the outset, I personally don’t think that snooty literary intellectuals (so-called) have much if anything at all to do with the current debased state of science education in America today.

But I think what we need to pause to contemplate here is not only the fact that Kristof thinks America’s superpowerful band of effete esthetes may indeed be a menace standing in the way of a more continent and respected practice of consensus science—implausibly enough, given the general disrepute and lack of funding that freights the actual lives of almost everybody who actually answers to anything like that job description—but that he thinks these snooty literary intellectual types constitute a larger problem to science education than crappy science education does.

“In the U.S. and most of the Western world, it’s considered barbaric in educated circles to be unfamiliar with Plato or Monet or Dickens, but quite natural to be oblivious of quarks and chi-squares.” What lovely cocktail parties Nick Kristof must be hobnobbing in! I must admit that I consider it delightful and rare to find myself in the company of anybody at all who is familiar with Dickens, Plato, or quarks for that matter.

“A century ago, Einstein published his first paper on relativity—making 1905 as important a milestone for world history as 1066 or 1789—but relativity has yet to filter into the consciousness of otherwise educated people.” I have to say that my circle of acquaintance rather differs from Kristof’s. Among the “educated people” I happen to meet—and I suspect Kristof means by this phrase formally educated people, which isn’t a usage I particularly approve of as it happens, but even in this restricted sense our experience seems to differ—I am quite as likely to talk to somebody who understands and can discuss relativity in a reasonably knowledgeable way as somebody who understands and can discuss Oscar Wilde or Dorothy Parker in a comparably knowledgeable way.

I must admit that I feel less eager to generalize from my own parochial experience in these matters, to go on to symptomize from there the state of American culture as a whole—probably one has to be a columnist for the New York Times or something comparably august before one begins to entertain such curious fancies. But I will say that my counterexample is enough, at least from a logical standpoint, to puncture the pretensions of Kristof’s own immodesty on this score.

In any case, against C. P. Snow’s reasonable and now rather notoriously framed worries about the radically disempowering consequences of general scientific ignorance in ever more conspicuously technoscientific societies, Kristof goes on to propose as apparently the one and only imaginable counterargument (he calls it “the counterargument” and leaves it at that, but the effect is much the same): “we can always hire technicians in Bangalore, while it’s Shakespeare and Goethe who teach us the values we need to harness science for humanity.”

In moments like these I have to wonder at Kristof’s earlier claim to be a representative of literary intellectual culture (one who seems especially keen to wallow masochistically, and quite unecessarily, in a lurid technicolor spectacle of self-hating self-blame at that), inasmuch as this sort of ethnocentric Arnoldian canon fluffing is hardly the sort of thing self-respecting literary intellectuals are comfortable indulging in these days. And curiously enough it tends to be because they are no longer eager props to such silly Establishmentarian parochialisms that such intellectuals tend to get charged with rampaging relativism and “fashionable nonsense” and anti-science pomo-paloozaism in the first place.

“[D]on’t pin too much faith on the civilizing influence of a liberal education,” Kristof sternly warns… somebody, who knows who, maybe this is some sort of premonitory admonition to his nineteenth century readers: “the officers of the Third Reich were steeped in Kant and Goethe.”

Yes, and Hitler was a vegetarian (actually, not really, but no matter). So, you know, I don’t know, be sure to eat cows or something or you might find yourself, and quite to your surprise, promoting genocide?

Ever so reasonably, Kristof soldiers on: “[S]imilar arguments were used in past centuries to assert that all a student needed was Greek, Latin and familiarity with the Bible—or, in China, to argue that all the elites needed were the Confucian classics.” Forgive my humanistic pedantry (I teach argumentation in a rhetoric department) but note well the restrictiveness entailed in the all in the phrase “all x needed was y” as opposed to the wonderfully qualified “some” in Kristof’s marvellously capacious alternative viewpoint: “Without some fluency in science and math, we’ll simply be left behind in the same way that Ming Dynasty Chinese scholars were.”

Not to put too fine a point on it, I’d say pretty much nobody who reads Kristof’s column with comprehension would argue that all the world needs are more Shakespearean scholars oblivious to basic science, and pretty much everybody who reads his column would agree as a matter of course that it’s good for people to understand science in a technoscientific society.

“Increasingly, we face public policy issues—avian flu, stem cells—that require some knowledge of scientific methods,” Kristof writes, and on this point he is obviously correct. “[Y]et,” he bemoans, “the present Congress contains 218 lawyers, and just 12 doctors and 3 biologists.”

I seem to recall that once upon a time at least one Senatorial doctor proposed to diagnose a medical condition via edited videotape, and so I don’t know that this sort of enumeration is exactly the best way of scouting out indications of scientific literacy. Most lawyers of my acquaintance have exhibited a more than quotidian knowledge of science—and though I seem to be more reticent about overgeneralizing from personal experience I know to be, at bottom, anecdotal, I don’t think I should allow Kristof the unwarranted suggestion that those knowledgeable in the law are therefore ignorant of science.

Anyway, I for one happen to think it is incomparably more relevant to note how many millionaires there are in Congress “representing” a nation of citizens the overabundant majority of whom are not millionaires, than noting how many of those millionaires are millionaire doctors versus millionaire lawyers. But, hey, that’s just me.

“In terms of the skills we need for the 21st century, we’re Shakespeare-quoting Philistines,” he scolds. Funny, and here I would say that where matters of scientific literacy are concerned the problem is that too many of us seem to be Bible-quoting fundamentalists.

A “disregard for science already hurts us,” Kristof continues. “The U.S. has bungled research on stem cells, perhaps partly because Mr. Bush didn’t realize how restrictive his curb on research funds would be.” This is nonsense, of course. Mr. Bush’s stupid and harmful policy here is a matter of genuflecting to his religious fundamentalist base.

“And we’re risking our planet’s future because our leaders are frozen in the headlights of climate change.” Again, arrant nonsense. Our “leaders” are frozen in the gunsights of their market fundamentalist corporate funders. Big pockets in extractive pollutive industries need climate-change denial to stay in business and probably imagine they can weather any actual catastrophic climate-change that ensues behind high walls in posh techno-bubble enclaves they can afford precisely because they profited so massively from these deceptions.

But, by all means, let’s direct our attention instead to America’s pernicious poets and theory-heads: “[T]here’s an even larger”—even larger!—“challenge than anti-intellectualism.” Wait for it. Wait for it. “And that’s the skewed intellectualism of those who believe that a person can become sophisticated on a diet of poetry, philosophy and history, unleavened by statistics or chromosomes. That’s the hubris of the humanities.”

Notice that once again people reading Mark Twain in English Departments and Hannah Arendt in Philosophy Departments are represented here as more menacing to reasonable policy-making than are the actively hostile endlessly documented efforts of religious fundamentalists and Big Business interests to compromise reasonable policy deliberation in the service of their parochial ends.

Apart from the psychological dimensions that must be afoot this nonsensical expression of hostility to the people with whom he claims to identify (only his therapist knows for sure), what is interesting in Kristof’s argument is that he seems to think there is something about a humanistic education (and I’m just bracketing for now all the facile overgeneralizations and weirdnesses that encumber the very notion of such a thing) that precludes a scientific education.

I, for one, know of almost no scholars in the humanities who would argue for a priority of literature over the sciences, whatever their own temperamental preferences in the matter—rather, most scholars seem to struggle to find the words with which to communicate the relevance and worth of literature in a world of businessmen, statisticians, and bomb builders mostly indifferent or even hostile to its attainments.

Contrary to Kristof’s rather rarefied impression, it seems to me the generous and critical sensibilities inculcated in the best humanistic education are almost completely disregarded in actually-existing American society, and very much to our cost. Surely I can claim to be in a position to contribute in some real if modest measure to my society in my chosen field without being misconstrued as claiming to speak alone, incomparable, and indispensable, from the summit of Philosopher Kings?

As somebody teaching in the almost catastrophically underfunded and widely disrespected humanities in America, let me remind Mr. Kristof that it is possible for most people to walk and chew gum at the same time, and I happen to think it not unreasonable to hope likewise for a world in which citizens understand the contribution of figures like William James and figures like Charles Darwin at the same time.

Needless to say, I agree that too many Americans are scientific ignoramuses, as innumerate as they are illiterate.

But as far as I’m concerned the blame for this calamity rests squarely on a culture that valorizes superficial short-term profit-taking over all else. In such a debased culture and anti-intellectual climate it seems to me pernicious in the extreme to indulge as Kristof seems to me to be doing in the gratuitous scapegoating of any of the few intellectuals who have managed to survive and testify to some alternative in the midst of this too thoughtless and hence too hopeless dance of death-dealing.

There is nothing more needful for, as well as nothing more vulnerable in, democratic civilization than the multiform expressions of human intelligence.

Fundamentalist religion and short-sighted greed, and certainly not the few post-Nietzschean intellectuals who rightly and forcefully anathematize such fundamentalism, are the real threats to a more proper role for consensus science in technoscientific societies. Anybody with any sense—whichever side of Snow’s “Two Cultures” divide or whichever position on the political spectrum one hails from—should surely understand this by now.

Hubble makes 3D dark matter map BBC News, Seattle
Astronomers have mapped the cosmic "scaffold" of dark matter upon which stars and galaxies are assembled.
Hubble's new 3D map shows the "clumpy" nature of dark matter
Dark matter does not reflect or emit detectable light, yet it accounts for most of the mass in the Universe. The study, published in Nature journal, provides the best evidence yet that the distribution of galaxies follows the distribution of dark matter. This is because dark matter attracts "ordinary" matter through its gravitational pull. Scientists presented details of their research during a news conference here at the 209th meeting of the American Astronomical Society (AAS) in Seattle, Washington. It involved nearly 1,000 hours of observations with the Hubble Space Telescope.
QUOTE("Prof Carlos Frenk - University of Durham")
For the first time, we can see what's really out there
According to one researcher, the findings provide "beautiful confirmation" of standard theories to explain how structures in the Universe evolved over billions of years. Ordinary matter - gas, stars, planets and galaxies - makes up just one-sixth of all matter in the Universe. The remainder is unseen. While previous studies of dark matter relied on simulations, this one details its large-scale distribution in 3D. For astronomers, the challenge of mapping the Universe has been described as similar to mapping a city from night-time aerial snapshots showing only street lights. Dark matter is invisible, so only the luminous galaxies can be seen directly. The new images are equivalent to seeing a city, its suburbs and country roads in daylight for the first time. Yet puzzling discrepancies remain.

Light bending
The map of mass distribution is based on measurements of about half a million distant galaxies. Lead author Richard Massey and his colleagues used a technique called weak gravitational lensing to detect the dark matter. To reach us, the light from galaxies has to pass through intervening dark matter.
The study traced subtle distortions in galactic light
This dark material bends light in much the same way as light is bent when travelling through a lens. "We understand statistically what those galaxies are supposed to look like," said Dr Massey, from the California Institute of Technology (Caltech) in Pasadena, US. "If you place some dark matter in the way, this dark matter - through its gravity - bends the path of light. "As the light gets deflected, it distorts the shape of the background galaxies. So we end up seeing them in a distorted way, as if through lots of little lenses - and each of those lenses is a bit of dark matter." To add 3D distance information, the Hubble observations were combined with multi-colour data from powerful ground-based telescopes. The map of dark matter distribution confirms that galaxy clusters are located within clumps of this invisible material. These clumps are connected via bridges of dark matter called filaments. The clumps and filaments form a loose network - like a web.

Cold and dark
Dr Eric Linder, from the Lawrence Berkeley National Laboratory, US, said the study was a "big step forward" in understanding the influence of dark matter on our Universe. "It's still a small fraction of the sky we're talking about - something like two square degrees out of 40,000 square degrees in total; but they are definitely the clearest pictures we have to date," he said.
The study involved nearly 1,000 hours of Hubble observations
Professor Carlos Frenk, from the University of Durham, UK, told BBC News: "The technique they used really is the future. "In the next decade, I think most studies of the Universe's large-scale structure will be dark matter structure studies. In this sense, I think galaxies will be relegated to a secondary role." He added: "For the first time, we can see what's really out there." The University of Durham astronomer said that, overall, the results were a "beautiful confirmation" of the cold dark matter theory on which he works. This theory is a leading model to explain how structures in the Universe evolved over cosmic time. Soon after the Big Bang, cold dark matter formed the first large structures in the Universe, which then collapsed under their own weight to form vast halos. The gravitational pull of these halos sucked in ordinary matter, providing a focus for the formation of galaxies.
