An anonymous reader writes to mention that while a couple of years ago researchers found that overweight people have a lower death rate than people with a normal weight, it may be more complicated than that. "Now, investigating further, they found out which diseases are more likely to lead to death in each weight group. Linking, for the first time, causes of death to specific weights, they report that overweight people have a lower death rate because they are much less likely to die from a grab bag of diseases that includes Alzheimer's and Parkinson's, infections and lung disease. And that lower risk is not counteracted by increased risks of dying from any other disease, including cancer, diabetes or heart disease."Read more of this storyat Slashdot.

  Hugh Pickens writes "Whose laws apply if astronauts from different countries get into a fight, make a patentable discovery, or damage equipment belonging to another country while on the International Space Station? According to the Outer Space Treaty of 1967, ratified by 98 nations, states have legal jurisdiction within spacecraft registered to them. When the space station was assembled from modules supplied by the United States, Russia, Japan and the European Space Agency (ESA), partners rejected an initial proposal that US law should prevail throughout the space station. "It was agreed that each state registers its own separate elements, which means that you now have a piece of the US annexed to a piece of Europe annexed to a piece of Japan in outer space, legally speaking," said Dr Frans von der Dunk of the International Institute of Air and Space Law at the University of Leiden. So what happens if a crime is committed in space? "If somebody performs an activity which may be considered criminal, it is in the first instance his own country which is able to exercise jurisdiction," Dr. von der Dunk added."Read more of this storyat Slashdot.

  An anonymous reader writes "On the Canary Islands last week, a team from Oerlikon Space demonstrated the feasibility of a laser link across a distance of 1.5 million kilometers for the first time ever. In the future, laser links like this one will be able to transmit data across huge distances through the universe far more rapidly and efficiently than is possible using conventional radio links today."Read more of this storyat Slashdot.

Ferran Adrià in Spain and Heston Blumenthal in England have been doing this for years, but the New York Times updates us on the ongoing experiments at WD-50 in New York City. Xanthan Gum, agar-agar, and other hydrocolloids are being used to bring strange effects to your food.

  An anonymous reader writes "Astronomers have detected a record-breaking 5th planet orbiting the star 55 Cancri, 41 light years distant. This planet orbits within the 'habitable zone,' where water could presumably exist, but it's probably another gas giant like Saturn, so any liquid water would have to be on a moon. There's still a big gap between this planet and the outermost planet where no planets have been detected yet, so there could yet be a rocky planet in the system. The lead researcher said he's optimistic that 'continued observations will reveal a rocky planet within five years.'"Read more of this storyat Slashdot.

  An anonymous reader writes "Researchers have found that toddlers treat a small robot as a peer rather than a toy. A team from the University of California, San Diego, placed Sony's QRIO in a classroom of kids aged 18 months to 2 years and watched them interact. Over time the children grew to treat the robot as one of them — playing games with the robot, hugging it, and covering it up with a blanket when its batteries ran down."Read more of this storyat Slashdot.

  An anonymous reader writes "With rapid-response surgery needed in Iraq and super-long-distance medicine a far-off necessity for a manned trip to Mars, NASA recently sent eight astronauts, roboticists and surgeons on its 'Vomit Comet,' pitting real doctors against new robotic ones. As if the prospect of a portable robo-OR deploying to Iraq by 2009 weren't enticing enough, one of the surgeons on board promised this in his flight blog: 'So far, surgery by hand is still the most efficient way to get the job done in a mobile, extreme environment. But robots are advancing rapidly... The solution that roboticists are working on now is to CAT scan a patient's entire body and beam the results back to Earth. Then a surgeon could program an operation and beam it back to upload into a robo-surgeon, which could carry out procedures like a player piano.'"Read more of this storyat Slashdot.

  Ponca City, We Love You writes "Researchers at the University Of Alabama In Huntsville have discovered that some x-rays thought to come from intergalactic clouds of 'warm' gas are instead probably caused by lightweight electrons — leaving the mass of the universe as much as ten to 20 percent lighter (in terms of its ordinary matter) than previously calculated. In 2002 the same team reported finding large amounts of extra 'soft' (relatively low-energy) x-rays coming from the vast spaces in the middle of galaxy clusters. Their cumulative mass was thought to account for as much as ten percent of the mass and gravity needed to hold together galaxies, galaxy clusters, and perhaps the universe itself. When the team looked at data from a galaxy cluster in the southern sky, however, they found that energy from those additional soft x-rays doesn't look like it should. 'The best, most logical explanation seems to be that a large fraction of the energy comes from electrons smashing into photons instead of from warm atoms and ions, which would have recognizable spectral emission lines,' said Dr. Max Bonamente. The work was published Oct. 20 in the Astrophysical Journal."Read more of this storyat Slashdot.

In a speech at the annual meeting of the Society for Neuroscience, he challenges big pharma companies, many of which haven't had an important new compound approved in ages, and academic researchers who are content with getting NIH grants and publishing research papers with little regard to whether their work leads to something that can alleviate disease, to change their ways.'"Read more of this storyat Slashdot.

  BBCWatcher writes "As Slashdot reported previously, Congress is pushing the U.S. Environmental Protection Agency to develop energy efficiency measures for data centers, especially servers. But IBM is impatient: Computerworld notes IBM has signed up Neuwing Energy Ventures, a company trading in energy efficiency certificates, in a first for "green" computing. Now if your company consolidates, say, X86 servers onto an IBM mainframe on top of slashing about 85% off your electric bill each megawatt-hour saved earns one certificate. Then you can sell the certificates in emerging carbon trading markets. IBM's own consolidation project (collapsing 3,900 distributed servers onto 30 mainframes) will net certificates worth between $300K and $1M, depending on carbon's market price. Will ubiquitous carbon trading discourage energy-inefficient, distributed-style infrastructure in favor of highly virtualized and I/O-savvy environments, particularly mainframes?"Read more of this storyat Slashdot.

  Dr. Eggman writes "Ars Technica reports on a new study that suggests not only that certain areas of the mouse genome undergo more changes, but that changes to those areas are more tolerable by the organism than changes in other areas. Recently published in Nature Genetics, the study examined the certain copy number variations of the C57Bl/6 strain in mice that have been diverging for less than 1,000 generations. The results were a surprising number of variations. While the study does not address it, Ars Technica goes on to recount suggestions that genomes evolved to the point where they work well with evolution."Read more of this storyat Slashdot.

The basic concept behind Draw-a-Secret is that humans excel at image recognition and memory, so 'passwords' should be designed to leverage that ability. The people behind the new work have refined the technique by parsing the shapes with a flexible grid and using existing images as a background to reinforce memory of the password.

  starseeker writes "At long last, the STIX project has posted a Beta release of their scientific fonts. The mission of the STIX project has been the 'preparation of a comprehensive set of fonts that serve the scientific and engineering community in the process from manuscript creation through final publication, both in electronic and print formats.' The result is a font set containing thousands of characters, and hopefully a font set that will become a staple for scientific publishing. Among other uses, it has long been hoped that this would make the wide scale use of MathML in browsers possible. Despite rather long delays the project has persisted and is now showing concrete results."Read more of this storyat Slashdot.
