  oliderid sends along a BBC report on progress toward Europe's home-grown GPS system. The Galileo concept will get an initial test via four "pathfinder" satellites that will be the first in the Galileo constellation. Galileo is intended to be complementary with the US GPS system — when all 30 Galileo birds are flying, a receiver with both GS and Galileo capability should enjoy 1-meter positional accuracy, vs. the several meters available through GPS alone, according to the article. There's a video tour of the facility where the pathfinders are being built. "After all the wrangling, the delays, and the furor over cost, Europe's version of GPS is finally starting to take shape. Due for launch in pairs in late 2010 and early 2011, the 'pathfinders' will form a mini-constellation in the sky. They will transmit the navigation signals that demonstrate the European system can become a reality."Read more of this storyat Slashdot.

  The Installer writes with this excerpt from an Associated Press report: "A couple of genetic testing companies are promising to match couples based on DNA testing, touting the benefits of biological compatibility. The companies claim that a better biological match will mean better sex, less cheating, longer-lasting love and perhaps even healthier children. 'How many dating services can you think of where they can suggest you might have better children?' said Eric Holzle, founder of ScientificMatch.com, one of the first online dating sites to use DNA. ... The idea is that people tend to be attracted to those who have immune system genes that are dissimilar from their own. Biologists say the HLA genes of the immune system — which are responsible for recognizing and marking foreign cells such as viruses so other parts of the immune system can attack them — also determine body odor 'fingerprints.' And people tend to be attracted to the natural body odors of those who have different HLA genes from their own."Read more of this storyat Slashdot.

  An anonymous reader writes "Robert X. Cringely once again educates and amuses with his take on how we could clean up the garbage that's in orbit around Earth. I cannot vouch for his math, but it makes sense to me. Quoting: 'We’d start in a high orbit, above the space junk, because we could trade that altitude for speed as needed, simply by flying lower, trading potential energy for kinetic. Dragging the net behind a little unmanned spacecraft my idea would be to go past each piece of junk in such a way that it not only lodges permanently in the net, but that doing so adds kinetic energy (hitting at shallow angles to essentially tack like a sailboat off the debris). But wait, there’s more! You not only have to try to get energy from each encounter, it helps if — like in a game of billiards or pool — each encounter results in an effective ricochet sending the net in the proper trajectory for its next encounter. Rinse and repeat 18,000 times.'"Read more of this storyat Slashdot.

By the fall of 2010, the team aims to start blasting capsules containing deuterium-tritium fuel with 1.4 megajoules of laser power, a first step towards the holy grail of controlled nuclear fusion. Not all are convinced that Moses will lead us to the promised land. 'They're snake-oil salesmen,' says Thomas Cochran, a scientist with the Natural Resources Defense Council.

  pickens writes "Denmark has unveiled official research showing that two-year-old children are at risk from a bewildering array of gender-bending chemicals in such everyday items as waterproof clothes, rubber boots, bed linen, food, sunscreen lotion, and moisturizing cream. A picture is emerging of ubiquitous chemical contamination driving down sperm counts and feminizing male children all over the developed world. Research at Rotterdam's Erasmus University found that boys whose mothers were exposed to PCBs and dioxins were more likely to play with dolls and tea sets and dress up in female clothes. 'The amounts that two-year-olds absorb from the [preservatives] parabens propylparaben and butylparaben can constitute a risk for oestrogen-like disruptions of the endocrine system,' says the report. The contamination may also offer a clue to a mysterious shift in the sex of babies. Normally 106 boys are born for every 100 girls: it is thought to be nature's way of making up for the fact that men were more likely to be killed hunting or in conflict. But the proportion of females is rising. 'Both the public and wildlife are inadequately protected from harm, as regulation is based on looking at exposure to each substance in isolation, and yet it is now proven beyond doubt that hormone disrupting chemicals can act together to cause effects even when each by itself would not,' says Gwynne Lyons, director of Chem Trust."Read more of this storyat Slashdot.

  tugfoigel writes "Astrophysicists atthe University of Warwick and Kiel University have discovered two bodies the size of earth with oxygen-rich atmospheres — however, there is a disappointing snag for anyone looking for a potential home for alien life, or even a future home for ourselves. These are not planets, but are actually two unusual white dwarf stars." The objects, 220 and 400 light-years distant, are believed to be remnants of stars between 7 and 10 solar masses. Such stars, the largest that evolve to white dwarves, have been sought for years. If the stars were a little more massive they would collapse to neutron stars, or so the theory goes. Here is the paper on the arXiv.Read more of this storyat Slashdot.

  An anonymous reader sends in this moderately disturbing quote from Gizmodo: "I'm touching a wet slab of protein, what feels like a paper-thin slice of bologna. It's supple, slimy, but unlike meat, if you were to slice it down the center today, tomorrow the wound would heal. It's factory-grown living tissue. The company behind the living, petri-dish-grown substance known as Apligraf hates my new name for it: meat band-aid. 'It's living,' Dr. Damien Bates, Chief Medical Officer at Organogenesis, corrects me. 'Meat isn't living.' But no one argues with me that this substance is really just a band-aid. A living, $1500 band-aid, I should say. Apligraf is a matrix of cow collagen, human fibroblasts and keratinocyte stem cells (from discarded circumcisions), that, when applied to chronic wounds (particularly nasty problems like diabetic sores), can seed healing and regeneration. But Organogenesis is not interested in creating boutique organs for proof of concept scientific advancement. They're a business in the business of mass tissue manufacturing — and the first of its kind."Read more of this storyat Slashdot.

  Pickens writes "The Telegraph reports that the Vatican's Pontifical Academy of Sciences is holding its first ever conference on alien life, the discovery of which would have profound implications for the Catholic Church. For centuries, theologians have argued over what the existence of life elsewhere in the universe would mean for the Church. Among other things, extremely alien-looking aliens would be hard to fit with the idea that God 'made man in his own image' and Jesus Christ's role as savior would be confused; would other worlds have their own Christ-figures, or would Earth's Christ be universal? Just as the Church eventually made accommodations after Copernicus and Galileo showed that the Earth was not the center of the universe, and when it belatedly accepted the truth of Darwin's theory of evolution, Catholic leaders say that alien life can be aligned with the Bible's teachings. 'Just as a multiplicity of creatures exists on Earth, so there could be other beings, also intelligent, created by God,' says Father Jose Funes, a Jesuit astronomer at the Vatican Observatory and one of the organizers of the conference. Others do not agree. 'If you look back at the history of Christian debate on this, it divides into two camps. There are those that believe that it is human destiny to bring salvation to the aliens, and those who believe in multiple incarnations,' says Paul Davies, a theoretical physicist. 'The multiple incarnations is a heresy in Catholicism.'"Read more of this storyat Slashdot.

  coondoggie writes "NASA's long-running Mars rover Spirit is stuck in a sand trap — a situation the space agency would like to fix. Yesterday NASA said it will begin what it called the long process of extricating Spirit by sending commands that could free the rover. Spirit has been stuck in a place NASA calls 'Troy' since April 23, when the rover's wheels broke through a crust on the surface that was covering bright-toned, slippery sand underneath. After a few drive attempts to get Spirit out in the subsequent days, it began sinking deeper in the sand trap. Driving was suspended to allow time for tests and reviews of possible escape strategies, NASA stated."Read more of this storyat Slashdot.

  NASA is reporting that preliminary data from the LCROSS mission indicates that there really is water in one of the permanently shadowed lunar craters, just as they suspected back in September. "'We are ecstatic,' said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center in Moffett Field, Calif. 'Multiple lines of evidence show water was present in both the high angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. The concentration and distribution of water and other substances requires further analysis, but it is safe to say Cabeus holds water.'"Read more of this storyat Slashdot.

  DynaSoar writes "On Friday November 13th, ESA'a Rosetta probe will get its third and final gravity assist slingshot from Earth on its way to its primary targets, the asteroid Lutetia and Comet 67P/Churyumov-Gerasimenko. But the slingshot itself will allow ESA scientists to examine the trajectory for unusual changes seen in several other probes' velocities. An unaccountable variation was first noticed as excess speed in Pioneers 11 and 12, and has since been called the Pioneer Anomaly. More troubling than mere speed increase is the inconsistency of the effect. While Galileo and NEAR had appreciable speed increases, Cassini and Messenger did not. Rosetta itself gained more speed than expected from its 2005 fly-by, but only the expected amount from its 2007 fly-by. Several theories have been advanced, from mundane atmospheric drag to exotic variations on special relativity, but none are so far adequate to explain both the unexpected velocity increases and the lack of them in different instances. Armed with tracking hardware and software capable of measuring Rosetta's velocity within a few millimeters per second while it flies past at 45,000 km/hr, ESA will be gathering data which it hopes will help unravel the mystery."Read more of this storyat Slashdot.

  cunniff writes "Wired Magazine points us to recent research that demonstrates an algorithm derived from the actual biological implementation of fly vision (PLoS paper here). Quoting the paper: 'Here we present a model with multiple levels of non-linear dynamic adaptive components based directly on the known or suspected responses of neurons within the visual motion pathway of the fly brain. By testing the model under realistic high-dynamic range conditions we show that the addition of these elements makes the motion detection model robust across a large variety of images, velocities and accelerations.' The researchers claim that 'The implementation of this new algorithm could provide a very useful and robust velocity estimator for artificial navigation systems.' Additionally, the paper describes the algorithm as extremely simple, capable of being implemented on very small and power-efficient processors. Best of all, the entire paper is public and hosted via a service that allows authenticated users to give feedback."Read more of this storyat Slashdot.

  astroengine writes "Physicists are getting excited about the possibility of micro-black holes (MBH) being produced by the LHC and an international group of researchers have done the math to see what kind of impact they could have on the Earth. Unfortunately, if you're a megalomaniac looking for your next globe-eating weapon, you can scrub MBHs off your WMD list. If a speedy MBH is produced, flying through our planet, it will only have a few seconds to accrete the mass of a few atoms. It would then be lost to space where it will evaporate. If a slow MBH is produced, dropping into the Earth where it sits for a few billion years, the results are even more boring."Read more of this storyat Slashdot.
