Wrighter writes "There's a new story at Yahoo about a new version of TCP called Fast TCP that might help increase the speed of file transfers. Sounds like it basically estimates the maximum efficient speed of your network, and then goes for it, dumping a lot of time-consuming error checking." There's also an article at the New Scientist with some additional information.

metz2000 writes "The New Scientist reports that the European Space Agency (ESA) has pledged hundreds of millions of Euros to guarantee its independent access to space. Europe also looks set to co-operate with the Russian Space Agency. Looks like the space industry is hotting up again. How will NASA react to this news after being the dominant space agency over the past three decades? A lot of money is going into rocket technology also; with this and the 'European version' of GPS are we heading towards a future conflict across the Atlantic?"

Makarand writes "Patients who have implants containing any kind of metal cannot be MRI scanned as the powerful electromagnetic radio waves can induce currents large enough to heat the metal in implants to over 70 C and damage surrounding tissue. Now, Biophan, a biomedical devices company, has developed a nano-coating material that can protect implants by preventing most of the radio waves from reaching the internal components of the implant by reflecting them. It's high electrical resistance also prevents currents from flowing around the implant's surface and heating any nearby body tissue. Biophan's coating is a mixture of poorly conducting nanoparticles held in an insulating matrix. The coating is a mere three micrometres thick and can cut the energy induced in an implant by 89 per cent."

Makarand writes "Geckos have the remarkable ability to climb the most smooth surfaces and hang from glass ceilings with a single toe. Their feet are covered with millions of nanoscopic keratin hairs that can exert an intermolecular force - called van der Waals force - producing an adhesive effect on surfaces they walk on. Researchers at Carnegie Mellon have been able to mimic the adhesive ability of Gecko feet with a synthetic material that could find applications in new types of vehicle tires or allowing robots to climb walls. The material is made by using a mould created by a lithographic process and consists of a flexibile and strong substrate covered with 100 million nanoscopic hair each centimetre square. It might take several more years before Gecko tape is made commercially available to the wanna-be Spiderman, but he will have to thank the Gecko for that, not the spider."

Makarand writes "Thanks to the availability of low cost high quality inkjet printers, crooks are now able to produce currency indistinguishable from the real banknotes, at least under dim lighting conditions like that in a bar or a nightclub. The term "digifeiters" is being coined for counterfeiters that use cheap high-resolution printers to produce fake currency. Unlike costly color xerographic copiers that come inbuilt with features to detect security details on banknotes and stop currency copying, no cheap printers come with such feature. An anti-digifeiting system for cheaper printers may consist of printer driver software capable of recognizing data patterns indicating currencies of several countries." I wonder what GimpPrint would think of being forced to print or not print certain documents based on their contents.

thyristor writes "'Researchers at MIT document the ultimate control over light: a way to shift the frequency of light beams to any desired colour, with near 100 per cent efficiency. This technology could revolutionise a range of fields, from turning heat into light, or even into prized terahertz rays - which hold great promise for medical imaging. It could also make it possible to focus a wide range of frequencies into a narrow band, make devices such as light bulbs and solar cells more efficient, and help to keep optical telecommunications networks moving.' These are probably the most exciting results in photonics in the last decade."

ekarjala writes "To avoid wing damage from foam separation in the future, NASA is planning a redesign of the existing shuttle. Seems to me it is time to consider a new design rather than a redesign -- let's take the lessons we've learned and create a space craft for the 21st century rather than re-treading a 30-year-old design."

Martian-mooncat writes "According to New Scientist Neptune is now entering a 40-year summer. The report says that cloud cover changes show Neptune has its own seasons, despite being 4.5 billion miles from the Sun. There are some pretty Hubble pics too!"

Your daily dose of spam... rjwoodhead writes "Hansard, the official journal of the UK parliament, reports on a recent discussion of spam in the House of Lords which not only mentions Monty Python, but reads like one of their skits." A New York spammer has been arrested. One account isn't scientifically representative, but it's a grim picture when you're showing a spam-doubling every 42 days. And an article in New Scientist suggests solving a puzzle, which is essentially the same idea as hash cash.

Makarand writes "An experimental one-person aircraft built by Boeing and powered by fuel cells could be ready for trials in Dec 2003. Once in the air the aircraft will be propelled by two 25-kilowatt fuel cells and will still rely on batteries to accelerate before taking off. If the propulsion system fails for any reason the aircraft will be capable of gently gliding back to earth. Boeing also has plans to replace re-chargeable batteries used on larger airplanes by fuel cells to cut down on pollution."

Bob Vila's Hammer writes "In an article at New Scientist, research scientists at the Wake Forest University School of Medicine in North Carolina have been able to breed a cancer-proof mouse. The lucky new finds, some 700 cancer-proof mice, have the ability to destroy numerous different kinds of cancer cells in their bodies very efficiently without the use of T-cells (white blood cells). Instead the body's innate immune system attacks the tumor cells and ruptures them with neutrophils and macrophages. What is so astounding within early findings is that the power of these mice to resist cancer seems to be unlimited and as well, a genetic trait able to be passed down to further generations without the negative results of previous mouse breeds with autoimmune diseases."

Digimax writes "The New Scientist has an interesting article on a technology being developed by NanoMagnetics which involves using a protein responsible for storing iron in the body to store data on a hard drive. Is this the start of the BioTech revolution?"

Maybe Linux UI people can get a jump on MS by making KDE/Gnome more accessible to more females."

Catskul writes "Along with the news that the polished and (more nearly) complete human genome being published Monday, comes a surprising observation about the genome: We have substantially fewer genes than expected; between 27,000 and 40,000 as compared to an original estimate of 140,000."

EzRag writes "According to this article in New Scientist, Russian scientists are preparing for a simulated mission to Mars, with six cosmonauts crammed into approx. 400 sq. meters for the length of the (simulated) journey. They'll bring with them all the food they'd need, and will recycle air and water. They will not, however, be exposed to simulated solar radition."

u19925 writes "Now you can get atomic clock precision out of your grandma pendulum clocks. Here is how it works: There is a camcorder fitted inside the clock which monitors the pendulum swing. It has an atomic clock signal receiver. It compares the pendulum swings with the atomic signal hearbeat. The camcorder also has an arm. If the pendulum clock drifts, then it uses its arm to push or pull the pendulum to make correction." It's not an April Fool's joke, but it is rather impractical.

StriderA writes "Robert Engel, of Queens College at The City University of New York, and colleagues have developed a new defence against bacteria and fungi.

wendyg writes "Thought some folks here might be interested in this interview with Patrick Ball, in which he talks about the work he's doing coding human rights violations into databases that can then be used for data mining to bring the perpetrators to book." This story from last October ("Why Human Rights Requires Free Software") mentions Ball's work in this area; this interview adds a broader look at what he's doing and why.

Makarand writes "Engineers may soon be able to make the finest optical fibers with some help from spiders. To make optical fibers narrower for nanoscale applications, researchers coated spider silk fibers with glassy material which was later removed by baking. The spider Stegodyphus pacificus, a native of the Middle East and South Asia, spins the thinnest known silk which promises to yield optical fibers with a diameter of around two nanometres!"

An anonymous reader writes "New Scientist reports: 'The music industry this week condemned the launch of two recording systems that will let people copy between 30 and 100 hours of music onto a single disc.'" The Sony system is supposed to use "ultra-efficient data compression system used in MiniDiscs" to fit "30 hours of MP3 music" on a CD-R. (I thought MD used ATRAC rather than MP3, and that ATRAC's standard bitrate was 285.3 Kbps -- can some MD gurus bring us up to speed?) Philips' system skips CDs, and instead uses a DVD burner, with the resulting disks playable in a to-be-released portable player. I wonder what kind of DRM features the companies will use to cripple each system.

jhouserizer writes "New Scientist is reporting that an artificial hippocampus is ready to undergo testing. The leader of the team of scientists is Theodore Berger of the University of Southern California in Los Angeles. They hope these artificial hippocampuses can replace damaged (stroke, Alzheimer's, etc.) portions of your brain. I wonder what portions of 'you' would be noticeably different to your family & friends? I wonder how long it will be before we can have HUDs, such as in this story by Cory Doctorow?"

WolfWithoutAClause writes "It's been known for decades that the universe is expanding. The current evidence points to this rate of expansion increasing, and if so, there's no obvious reason why the expansion rate couldn't continue to increase ever faster. A physicist, Simon Caldwell, has taken this to inevitable conclusion and suggested the expansion will eventually reach a point where the expansion rate is so high that any surviving people will ripped apart, followed a millisecond later by the destruction of all the atoms in the universe. Ouch. New Scientist says we may only have 22 billion years left. Almost enough time for a quick game of Everquest then."

China being having a space program is only one (profound) question. Another one is whether we should be mining the moon: I'm sure the more 'vocal' conservationalists have one opinion. What about mining asteroids?"

markthebrewer writes "From an article in the New Scientist: Conventional wisdom every 15 year-old knows says that you can't mix oil and water without some kind of surfactant. However a team lead by Richard Pashley from the Australian National University in Canberra have done it simply by first removing all dissolved gases from the water. Apart from the obvious potential improvements in salad dressings, it could have an impact on the manufacture of everything from drugs to paint - anywhere an emulsion is required. Apparently, it will also give some insight into the mysterious 'long-range hydrophobic effect' (or why oil droplets coalesce over surprisingly long distances)." Keep in mind the usual scientific caveat: this experiment doesn't seem to have been replicated by other experimenters yet.

Peter_Pork writes "New images sent back by NASA's Mars Odyssey have prompted an interesting theory about Martian gullies, as reported today by Washington Post and New Scientist. Odyssey's images show snow accumulations near the gullies, suggesting that the gullies were formed by melted snow. Scientists have developed a new weather model based on 100,000-year cycles in which snow first accumulates in highlands and it is then melted by the action of the sun. Liquid water, protected from evaporation by a superficial layer of snow, would carve the gullies in a few thousand years. This idea gives further hope to the search of life forms in Mars, since liquid water is suitable for sustaining life. Upcoming landings (three in the next two years) should shed more light on the question, but they will most likely not land in the rocky areas where this phenomenon occurs."

Zorgatron writes "New Scientist reports that a researcher from Cornell University has come up with clever method of identifying what's cool by automatically searching weblogs. Sudden increases or "bursts" in the usage of particular words may reflect a new craze, according to Jon Kleinberg. He has demonstrated the technique by searching through state of the union addresses given since 1790." I wonder how long before this can be done real time enough to really make this useful.

Strigiform writes "Some of the questions about the early universe have been answered by the WMAP project as reported by New Scientist. The inflation theory of the early universe has been vindicated, as it correctly predicted the polarisation of microwaves observed. The earliest stars appeared only 200 million years after the Big Bang and the universe is about 13.7 billion years old"

Makarand writes "A Canadian company is developing a flexible solar-power generating material that can be draped over any building. This will allow buildings with curves and complex shapes to use solar panels. The new material is made of silicon beads, each acting as a solar cell, placed between two aluminum foils and sealed on the sides with plastic. The manufacturing process for the silicon beads can use waste silicon from the chip-making industry. The material has an overall efficiency of 11 per cent which is comparable to the performance of conventional photovoltaic cells. The material looks like blue denim and architects might love to work with it."

Gavinsblog writes "New Scientist is reporting that using a technique called quantitive genetics, researchers have found that due to the effects of global warming, female squirrels now give birth on average 18 days earlier in the year than their great-great-grandmothers.
