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.

  Roland Piquepaille writes "You probably know that it is easy to combine hydrogen and oxygen to make water. After all, this chemical reaction is known for more than two centuries. But now, researchers at the University of Illinois at Urbana-Champaign (UIUC) have discovered a new way to make water. As states the UIUC report, 'not only can they make water from unlikely starting materials, such as alcohols, their work could also lead to better catalysts and less expensive fuel cells.' But be warned: don't read the technical paper itself. It could win an obfuscated contest — if such a contest existed for scientific papers." Yet another advance in fuel cell technology; we discussed a different one just the other day.Read more of this storyat Slashdot.

  aalobode writes "The Times of London has a current story based on the review of a book by Alex Boase, Elephants on Acid and Other Bizarre Experiments. There they list the top science experiments — including the one from which the book gets its name — that were conducted by otherwise sane humans who tragically or otherwise ignored the effect of their research on the subjects themselves. Nowadays, most institutions have a review board for research on human subjects which would flag most proposals that could lead to harm for the subjects, but not so in the past. 'Another 1960s experiment, in which ten soldiers on a training flight were told by the pilot that the aircraft was disabled, and about to ditch in the ocean. They were then required to fill in insurance forms before the crash -- ostensibly so the Army was not financially liable for any deaths or injuries. They were actually unwitting participants in an experiment: the plane was not crippled at all. It revealed that fear of imminent death indeed causes soldiers to make more mistakes than usual when filling in forms.'"Read more of this storyat Slashdot.

  MarkWhittington writes "Andrew Smith, the author of Moondust: In Search of the Men Who Fell to Earth, recently published a polemic in the British newspaper The Guardian, entitled Plundering the Moon, that argued against the economic development of the Moon. Apparently the idea of mining Helium 3, an isotope found on the Moon but not on the Earth (at least in nature) disturbs Mr. Smith from an environmentalist standpoint. An examination of the issue makes one wonder why."Read more of this storyat Slashdot.

  Roland Piquepaille writes "Researchers at the University of Houston (UH) have developed a new platinum-based catalyst for fuel cells that is at least four times more efficient and cheaper than existing catalysts. This discovery in fuel cell research may ease reliance on gasoline. According to the researchers, the active phase of the catalyst consists of nanoparticles with a platinum-rich shell and a core made of an alloy of copper, cobalt, and platinum. But it's not enough for this new catalyst to be more efficient and cheaper than a pure platinum one. It also needs to work for a long time — say, the life of a car. So far, the preliminary results look promising, but longer-term testing is needed before this kind of fuel cells can be used to power your car."Read more of this storyat Slashdot.

  Hugh Pickens writes "According to recent research, huge amounts of sulphur dioxide released by volcanic eruptions may have had more to do with wiping out dinosaurs than the meteorite strike at Chicxulub on Mexico's Yucatán Peninsula. Marine sediments drilled from the Chicxulub crater have revealed that that the mass extinctions occurred 300,000 years after Chicxulub hit Earth. The Deccan volcanism was a long cumulative process that released vast amounts of greenhouse gases into the atmosphere. '"On land it must have been 7-8 degrees warmer," says Princeton University paleontologist Gerta Keller. "The Chicxulub impact alone could not have caused the mass extinction, because this impact predates the mass extinction."' Keller also postulates a second larger and still unidentified meteor strike after Chicxulub, that left the famous extraterrestrial layer of iridium found in rocks worldwide and pushed earth's ecosystem over the brink. But where's the crater? "I wish I knew," says Keller."Read more of this storyat Slashdot.

  rufey writes "This week there have been two pieces of bad news from the International Space Station. First was the discovery of metal shavings inside a problematic rotary joint used to keep one set of solar panels in the optimal position for power generation. At the close of a subsequent spacewalk, after it was relocated to its permanent location, the unfurling of the 4B solar panel resulted in it tearing in two places. A spacewalk is now planned for November 4th to attempt to fix the tear. The upcoming spacewalk is not without risks, including the remote possibility of electrocution since it is impossible to stop the solar panel from generating electricity during the repair attempt. NASA says the ripped wing needs to be fixed or the solar rotary joint problem solved before any more shuttles can fly to the space station and continue construction. With a hard deadline of 2010 for Shuttle retirement, NASA does not have much wiggle room in the schedule in order to finish ISS construction."Read more of this storyat Slashdot.

  Stony Stevenson writes "A group of researchers at Florida state have demonstrated a magnet design that could shed new light on nanoscience and semiconductor research. 'The Split Florida Helix magnet can direct and scatter laser light at a sample down the centre of the magnet and from four ports on the sides. Due to become fully operational in 2010, the device can generate fields above 25 tesla. The highest-field split magnet in the world currently attains 18 tesla ... The scientists will be able to expand the scope of their experimental approach, learning more about the intrinsic properties of materials by shining light on crystals from angles not previously available in such high magnetic fields.'"Read more of this storyat Slashdot.

  Identity Missing writes "An Ohio laboratory has produced genetically modified mice which 'can run five to six kilometres at a speed of 20 meters per minute on a treadmill, for up to six hours before stopping,' as well as a number of other remarkable feats. An enzyme called phosphoenolypyruvate carboxykinases (PEPCK-C) is apparently responsible, and we should hope that the scientists are correct in saying that athletes won't be modifying their genes any time soon to get it, because it apparently makes the mice more aggressive. If anyone feels a super villain coming on, at least we can rely on these Mighty Mice. A video demonstrates just how much these little guys beat the competition."Read more of this storyat Slashdot.

  Ian Lamont writes "An Arizona State University researcher named Michael Kozicki claims that nanotechnology will replace disk drives in ten years. The article mentions three approaches: Nanowires (which replaceelectrons/capacitors), multiple memory layers on silicon (instead of a single layer), and a method that stores multiple pieces of information in the same space: 'Traditionally, each cell holds one bit of information. However, instead of storing simply a 0 or a 1, that cell could hold a 00 or a 01. Kozicki said the ability to double capacity that way — without increasing the number of cells — has already been proven. Now researchers are working to see how many pieces of data can be held by a single cell.'"Read more of this storyat Slashdot.

  markmcb writes "Most everyone is familiar with the concept of the lottery, i.e., random numbers are selected and people guess what they will be for a cash prize. But how random are the numbers? Matt Vea has conducted a pattern analysis of the MegaMillions lottery, which recently offered a sum of $370M (USD) to the winner. Matt shows that the lottery isn't as random as it may seem and that there are 'better' choices than others to be made when selecting numbers. From the article, 'A single dollar in MegaMillions purchases a 1 in 175,711,536 chance of landing the jackpot ... a player stands a mildly better chance of winning a partial prize through the selection of weighted numbers.'" Includes some excellent charts of his analysis.Read more of this storyat Slashdot.

  Invisible Pink Unicorn writes "Researchers at the National Science Foundation have utilized a single carbon nanotube to perform all the functions of a standard radio, acting as an antenna, tunable filter, amplifier, and demodulator. They were then able to tune in a radio signal generated in the room and play it back through an attached speaker. The device is functional across a bandwidth widely used for commercial radio. From the NSF: 'The source content for the first laboratory test of the radio was "Layla," by Derek and the Dominos, followed soon after by "Good Vibrations" by the Beach Boys.'"Read more of this storyat Slashdot.

  wattrlz writes "In a development reminiscent of nineteenth century pseudo-science, the father-son team of Kong Thon and Shaw Wei Tsen recently demonstrated that the tobacco mosaic virus can be destroyed in vitro by nano-scale mechanical resonant vibrations induced by repeated ultra-short pulses from a laser. The total energy required is reportedly far below the threshold for human tissue damage and the technique should generalize to human pathogens. Cleaning stored blood is one obvious application."Read more of this storyat Slashdot.

  mcgrew writes "New Scientist is reporting that "non-human primates really can understand the meaning of numerals." The small study of two rhesus monkeys reveals that cells in their brains respond selectively to specific number values — regardless of whether the amount is represented by dots on a screen or an Arabic numeral. For example, a given brain cell in the monkey will respond to the number three, but not the number one. The results suggest that individual cells in human brains might also have a fine-tuned preference for specific numerical values." The report itself is online at PLoS Biology, Semantic Associations between Signs and Numerical Categories in the Prefrontal Cortex."Read more of this storyat Slashdot.
