NASA Suggests Nano Robots To Explore Mars 104

destinyland writes "'We're going to have to do extensive robotic exploration,' says the director of NASA's Ames Research Center, suggesting nanotechnology to build self-replicating robots on Mars. Genetically engineering extraction and construction microbes could 'grow' electrical components, and eventually convert carbon dioxide on Mars into oxygen. 'If we really want to settle Mars, and we don't want to have to carry millions of tons of equipment with us to duplicate the way we live on Earth, these technologies will be key.' This interview with Peter Worden, the director of NASA's Ames Research Center, was just featured in the summer issue of H+ magazine, and he also argues that robots will be necessary to first survey Mars for underground microbes and protect the unique Martian biosphere, since it may contain clues about earth's own first life forms. In fact, given the water and carbon that's been discovered on Mars, the possibility of underground microbes is still considered real, and Worden argues that Mars 'may already be supporting life.'"

The Incredible Shrinking Genome 113

Shipud writes "Mammalian genomes have been shrinking for about 65 million years, roughly since the dinosaur extinction. Why? And why were ancient mammalian genomes three times larger than they are today? A new article in Genome Biology and Evolution tries to explain this bizarre finding, and why the genomes of mammals (but not of other living groups) are still shrinking. 'Once [the dinosaurs] were gone, mammals started to radiate, fill those niches, and a whole new level of competition arose. The selective advantage of not having a genome encumbered by potentially damaging mobile DNA elements has probably become critical at this "be ye fruitful and multiply; bring forth abundantly in the earth, and multiply therein" stage. In effect, the genomes of mammals has been shrinking by removing mobile DNA elements, just after the KT boundary. And according to the model presented in this study, this process is still ongoing: mammalian genomes are not at an equilibrium size. Unlike flies, mammals are still cleaning up.'"

Submission + - Comets Probably Seeded Earth's Nitrogen Atmosphere (technologyreview.com)

KentuckyFC writes: "One of the biggest puzzles of astrobiology is the origin of the Earth's oceans and atmosphere. One favoured theory is that our water is the leftovers from a bombardment of comets early in Earth's history. But the ratio of hydrogen and deuterium in the oceans doesn't match the ratio in the four comets measured so far (Halley's, Hyakutake, Hale-Bopp and C/2002 T7 LINEAR). Now a new analysis of the ratio of nitrogen-14 and 15 isotopes in these comets and on Earth places new limits on how much of our environment could have come from comets. On the one hand, the astronomers who did the work say that no more than a few percent of Earth's water could have come from comets. But on the other, they say that the ratio of nitrogen isotopes in these comets almost exactly matches the ratio in Earth's atmosphere. That suggests that while Earth's oceans must have come from somewhere else, Earth's early atmosphere was probably seeded by comets."

Submission + - Hackers target Neopets users

An anonymous reader writes: If you have children that play on the popular virtual world game Neopets, you might want to warn them of a social engineering scam gleefully targeting "twelve year old kids". Neopets users looking for rare items are sent private messages from the hackers, who direct them to sites hosting keyloggers & trojans. They then use the infected PC as a means to get to data the parents might have stored there, be it credit card details, Paypal accounts or online banking. Seeing the screenshots of some of these people talking about putting these children into botnets is just unbelievable — if ever you wanted proof that people up to no good online will go to any lengths to get their hands on some money (or even just feel good about outsmarting a twelve year old), here it is.

Pirate Bay Announces Sale to Swedish Company For $7.8 Million 406

paulraps writes "The Pirate Bay is to be bought for $7.8 million by Global Gaming Factory X, a Swedish company specializing in internet café management software, the company has announced. As well as taking over the controversial brand, GGF has also bought Peerialism, a small IT company with roots at Sweden's Royal Institute of Technology, which has developed a new file sharing technology. The acquisitions mean that GGF will be at the heart of 'the international digital distribution market,' allowing it to introduce a new pay model for file sharing." Reader pyzondar adds "However, the press statement also states that the deal will only go through 'if GGF and its Board of Directors can use the asset in a legal and appropriate way.'"

Microsoft Rebrands Live Search As "Bing" 443

JacobSteelsmith writes "Microsoft is attempting to re-brand its Live Search, also known as Kumo. Bing, as it's known, is another attempt by Microsoft to lure consumers away from Internet search leaders such as Google. Microsoft has posted a quarterly loss in its online advertising business, compared to Google's sales, $4.7 billion in the first quarter. According to the Live Search blog, Bing goes 'beyond the traditional search engines to help you make faster, more informed decisions' by combining a 'great search engine' with organized results. It also adds unique tools to help the user make important decisions. It is being touted as a 'decision engine.'"

Pulsar Signals Could Provide Galactic GPS 146

KentuckyFC writes "We're all familiar with GPS. It consists of a network of satellites that each broadcast a time signal. A receiver on Earth can then work out its position in three-dimensional space by comparing the arrival times of the signals from at least three satellites. That's handy, but it only works on Earth. Now astronomers say that the millisecond signals from a network of pulsars could allow GPS-style navigation on a galactic scale. They propose using four pulsars that form a rough tetrahedron with the Solar System at its center, and a co-ordinate system with its origin at 00:00 on 1 January 2001 at the focal point of the Interplanetary Scintillation Array, the radio telescope near Cambridge in the UK that first observed pulsars. The additional complexity of working with signals over these distances is that relativity has to be taken into account (which is why the origin is defined as a point in space-time rather than just space). The pulsar GPS system should allow users to determine their position in space-time anywhere in the galaxy to within a few nanoseconds, which corresponds to an accuracy of about a meter." Pulsars slow down over time, and the arXiv paper doesn't seem to mention this. The paper is mainly about establishing a coordinate system and a reference selection of pulsars. Any proposed Galactic Positioning System would have to take the slowing into account, and since it is poorly understood and not completely predictable, this would limit accuracy.

How IBM Plans To Win Jeopardy! 154

wjousts writes "Technology Review is reporting on IBM's plans to take on Trebek at his own game. The 'Watson' computer system uses natural-language processing techniques to break down questions into their structural components and then search its database for relevant answers. A televised matchup with Trebek is planned for next year. 'David Ferrucci, the IBM computer scientist leading the effort, explains that the system breaks a question into pieces, searches its own databases for "related knowledge," and then finally makes connections to assemble a result. Watson is not designed to search the Web, and IBM's end goal is a system that it can sell to its corporate customers who need to make large quantities of information more accessible.'"

Voyager Clue Points To Origin of the Axis of Evil 293

KentuckyFC writes "Cosmologists have been scratching their heads over the discovery of a pattern imprinted on the cosmic microwave background, the radiation left over from the Big Bang. This pattern, the so-called Axis of Evil, just shouldn't be there. Now an independent researcher from Canada says the pattern may be caused by the boundary between the Solar System and interstellar space where there is a sharp change in pressure, temperature and density of ions in space. Known as the termination shock, astronomers had thought this boundary was spherical. But last year, data from the Voyager spacecraft which have crossed the boundary, showed it was asymmetric. The new thinking is that the termination shock acts like a giant lens, refracting light that passes through it. Any distortion of the lens ought to show up as a kind of imprinted pattern on an otherwise random image. But the real eye-opener is that as the shape of the termination shock changes (as the Solar Wind varies, for example), so too should the pattern in the microwave background. And there is tentative evidence that this is happening too (abstract)."

Bill Would Declare Your Blog a Weapon 780

Mike writes "Law prof Eugene Volokh blogs about a US House of Representatives bill proposed by Rep. Linda T. Sanchez and 14 others that could make it a federal felony to use your blog, social media like MySpace and Facebook, or any other Web media 'to cause substantial emotional distress through "severe, repeated, and hostile" speech.' Rep. Sanchez and colleagues want to make it easier to prosecute any objectionable speech through a breathtakingly broad bill that would criminalize a wide range of speech protected by the First Amendment. The bill is called The Megan Meier Cyberbullying Prevention Act, and if passed into law (and if it survives constitutional challenge) it looks almost certain to be misused."

Ugobe, Maker of Pleo, Files For Bankruptcy 79

AshboryBassPlayer writes "Ugobe has filed for Chapter 7 bankruptcy — i.e., not reorganization but liquidation. We first discussed the company's Pleo robotic dinosaur toy in 2006. According to the company, 100,000 Pleos were sold in 2008. CEO Caleb Chung is optimistic about the auction value of intellectual property that Ugobe holds. Pleo featured 14 servo joints, a camera, and an SD Card for storage. The final street prices were commonly between $275 and $350, much higher than an earlier hoped-for price point under $200."

Ubuntu 9.04 Released 620

Mohamed Zaian writes "Canonical, the commercial sponsor of Ubuntu, announced today that Ubuntu 9.04 Desktop Edition is free to download from Thursday 23 April. Also announced were the simultaneous releases of Ubuntu 9.04 Server Edition and Ubuntu 9.04 Netbook Remix (UNR). Ubuntu 9.04 Desktop Edition delivers a range of feature enhancements to improve the user experience. Shorter boot speeds, some as short as 25 seconds, ensure faster access to a full computing environment on most desktop, laptop and netbook models. Enhanced suspend-and-resume features also give users more time between charges along with immediate access after hibernation. Intelligent switching between Wi-Fi and 3G environments has been broadened to support more wireless devices and 3G cards, resulting in a smoother experience for most users."

Microsoft Warns of Copycat Conficker Worm 86

nk497 writes "Microsoft is warning that malware writers have adapted a four-year-old virus to use features of Conficker to take advantage of Windows flaws. Other similarities between the adapted Neeris worm and Conficker are that it downloads a copy of the worm from the attacking machine using HTTP, spreads via autorun, and uses a driver to patch the TCP/IP layer of the system. It even saw a traffic jump around the first of April, when the Conficker hype peaked. But the Microsoft researchers suggested Conficker may have copied Neeris, or that they're copying each other: 'It is possible that these miscreants somehow collaborate or at least are aware of each other's "products."'"
