krou writes "A team from Surrey Space Centre has developed a device called a CubeSail, designed to be attached to satellites and rocket stages in order to drag space debris from orbit. CubeSail is a nanosatellite, weighing 3kg (6.6lb), and measures 10cm x 10cm x 30cm. Within its frame is a polymer sheet that unfurls itself once in space. 'The simple deployment mechanism features four metal strips that are wound under tension and will snap into a straight line when let go, pulling the sheet flat in the process.' The overall idea is that 'Residual air molecules still present in the spacecraft's low-Earth orbit will catch the sheet and pull the object out of the sky much faster than is normal.' Sir Martin Sweeting, the chairman of SSTL, who supported the research, said, 'We would be looking to put it on our own satellites and to put it on other people's spacecraft as well. We want this to be a standard, essential bolt-on item for a spacecraft; and that's why it's very important to make it small, because if it's too big it will interfere with the rest of the spacecraft.' The team is also hoping that CubeSail can act as a propulsion system, using 'solar sailing' to help satellites keep their orbits more efficiently."

Ada_Rules writes "Researchers at the Imperial College London have announced development of an alcohol substitute that has many of the same properties as the Synthehol from the series Star Trek, in that one will get a buzz from it but will not end up with a hangover. In addition you will have the option of getting immediately sober if you so desire it. Let's hope this is not the typical vaporware. It is not that I really want a drink of Synthehol, but with its release I assume Romulan Ale won't be far behind."

eldavojohn writes "Previous estimates are now thought to skimp on the entropy of the observable universe. The researchers contend that super-massive black holes are the largest contributor of entropy. Since they contribute two orders of magnitude more than previously thought, the total of all the observable universe is correspondingly higher. The paper highlights (in gruesome detail) new issues that arise with these new calculations — like estimating us a little bit closer to heat death (moving entropy totals from 10^102 to 10^104 out of a maximum of 10^122)."

An anonymous reader points out a story in Wired introducing us to the Doomsday Machine built by the Soviet Union in the 1980s — and that remains active to this day. It was called "Perimeter." The article explains why the device was built, and why the Soviets considered it to be something that kept the peace, even though they never told the US about it. "[Reagan's] strategy worked. Moscow soon believed the new US leadership really was ready to fight a nuclear war. But the Soviets also became convinced that the US was now willing to start a nuclear war. ... A few months later, Reagan... announced that the US was going to develop a shield of lasers and nuclear weapons in space to defend against Soviet warheads. ... To Moscow it was the Death Star — and it confirmed that the US was planning an attack. ... By guaranteeing that Moscow could hit back, Perimeter was actually designed to keep an overeager Soviet military or civilian leader from launching prematurely during a crisis. The point, [an informant] says, was 'to cool down all these hotheads and extremists. No matter what was going to happen, there still would be revenge. Those who attack us will be punished.'"

stavros-59 writes "Australia's internet censorship watchdog, ACMA, uses an internet classification system originally intended for children's PC filters. ACMA has now made what must be the most amazing recent decisions of the whole bizarre censorship debate. The Register today has a story about ACMA's decision to force Apple to withdraw their ITMS gift feature from Australia on the basis that MA+ (over 15 and maybe sex) rated movies could not be given to children using the gift cards. The films are also banned on the internet but not at local video/DVD stores as detailed in this Whirlpool Forum post. At the same time, the photographic work of Robert Mapplethorpe (not for the fainthearted) has been classified as PG (Parental Guidance) by the Classification Board — which is not part of ACMA, but an agency under the Attorney General's Department."

mmmscience writes "A group of scientists has identified a structure in the brain of psychopaths that is abnormal when compared with controls. The change is found in the uncinate fasciculus, a bridge of white matter that connects the amygdala (emotion/aggression brain region) and the orbitofrontal cortex (decision making region). Interestingly, the greater the abnormality in the region, the more severe the levels of sociopathy in a subject. The results were published as 'Altered connections on the road to psychopathy' in the journal Molecular Psychiatry. A researcher on the team suggests the finding could have considerable implications in the world of criminal justice, where such scans could one day be presented as evidence in a trial." The study's results have not yet been replicated by other researchers.

Peter writes "Toyota researchers have unveiled a new humanoid robot that can run at 7 km/h, which is faster than Honda's humanoid robot ASIMO. Toyota's robot can also keep itself balanced when pushed, as shown in the video."

Oracle Goddess writes "In a story just dripping with irony, Amazon Kindle owners awoke this morning to discover that 1984 and Animal Farm had mysteriously disappeared from their e-book readers. These were books that they had bought and paid for, and thought they owned. Apparently the publisher changed its mind about offering an electronic edition, and apparently Amazon, whose business lives and dies by publisher happiness, caved. It electronically deleted all books by George Orwell from people's Kindles and credited their accounts for the price. Amazon customer service may or may not have responded to queries by stating, 'We've always been at war with Eastasia.'"

movesguy sends us to The Daily Galaxy for comments by Stephen Hawking about how humans are evolving in a different way than any species before us. Quoting: "'At first, evolution proceeded by natural selection, from random mutations. This Darwinian phase, lasted about three and a half billion years, and produced us, beings who developed language, to exchange information. I think it is legitimate to take a broader view, and include externally transmitted information, as well as DNA, in the evolution of the human race,' Hawking said. In the last ten thousand years the human species has been in what Hawking calls, 'an external transmission phase,' where the internal record of information, handed down to succeeding generations in DNA, has not changed significantly. 'But the external record, in books, and other long lasting forms of storage,' Hawking says, 'has grown enormously. Some people would use the term evolution only for the internally transmitted genetic material, and would object to it being applied to information handed down externally. But I think that is too narrow a view. We are more than just our genes.'"

Xeger writes "University of Chicago researchers have found that streams of sand can behave in a similar manner to liquids, forming water-like droplets when poured from a funnel. To obtain these results, they dropped their expensive high-speed camera from a height of several meters and observed the sand forming into droplets — something that shouldn't happen without surface tension. These findings suggest that conventional engineering wisdom about sand, dirt and other grainy materials needs to be rethought, and that it might be possible to apply fluid dynamics to some solids problems."

Glyn Moody writes "Open source projects are generally fine when there's a long-term leader like Linus; but what happens when nobody is able or willing to run things for extended periods? Peter Murray-Rust explains how the open chemistry group known as the Blue Obelisk has evolved what he calls the 'Doctor Who Model of Open Source': 'You'll recall that every few years something fatal happens to the Doctor and you think he is going to die and there will never be another series. Then he regenerates. The new Doctor has a different personality, a different philosophy (though always on the side of good). It is never clear how long any Doctor will remain unregenerated or who will come after him. And this is a common theme in the Blue Obelisk.' Could other open source projects learn from this experience as long-term leaders start to move on?"

An anonymous reader writes "The Australian Government is keen to replicate the success of the Cochlear Implant (bionic ear) by throwing AU$50M (US$40M) of funding at the development of a bionic eye. Bionic eyes have been trialed with some success in the UK — with recipients able to detect senses of shape and space, but very little detail."

blakeharris snips from a site called The X-Journals: "Nick Pope used to work for the British Ministry of Defense and for 3 years headed up their UFO project. His remit was to investigate UFO sightings reported to the British government, looking for evidence of any potential threat, or anything judged to be of any 'defence significance.'" Some very interesting anecdotes in here, as well as some background on how certain files about these sightings came to be preserved in the first place.

An anonymous reader writes "After the astronauts on the International Space Station finished up their communications with Space Shuttle Atlantis yesterday, the crew on the Space Station did something that no other astronaut has ever done before — drank recycled urine and sweat. The previous shuttle crew that recently returned to Earth brought back samples of the recycled water to make sure it was safe to drink, and all tests came back fine. So on Wednesday, the crew took their recycled urine and said 'cheers' together and toasted the researches and scientists that made the Urine Recycler possible. After drinking the water, they said the taste was great! They also said the water came with labels on it that said 'drink this when real water is over 200 miles away.'"

sciencehabit writes "'Researchers have developed a material that almost instantaneously (30 ms) changes from clear to dark blue when exposed to ultraviolet light, and it just as quickly reverts to clear when the light is turned off. The new material, one of a class called photochromics, could be useful in optical data storage as well as in super-fancy sunglasses.'" A comment to the article notes some of the potential dangers of quick-change sunglasses.
