ethericalzen writes "A BBC article highlights a theory that the first stars may have been powered by dark matter. A group of US scientists published a paper in Physical Review Letters speculating that, unlike the stars of today, which are powered by nuclear fusion, early stars might have been powered by the abundant dark matter crowding the universe after the Big Bang. The theory suggests that these stars would have collided and destroyed one another before nuclear fusion had a chance take hold." The BBC perhaps overstates the certainty with which the dark-matter theory is held, and doesn't mention that the postulated properties of such particles are completely speculative.

philetus writes "An article in New Scientist describes a robotic system composed of swarms of electromagnetic modules capable of assuming almost any form that is being developed by the Claytronics Group at Carnegie Mellon. 'The grand goal is to create swarms of microscopic robots capable of morphing into virtually any form by clinging together. Seth Goldstein, who leads the research project at Carnegie Mellon University, Pittsburgh, in the US, admits this is still a distant prospect. However, his team is using simulations to develop control strategies for futuristic shape-shifting, or "claytronic", robots, which they are testing on small groups of more primitive, pocket-sized machines.'"

egil writes "Trolltech announced this morning (CET) that they have accepted a bid from Nokia to buy the entire company. The bid was for 16 NOK per share, which values the company at an equivalent of approximately 150 million USD. The stock currently trades at 15.70 on the Oslo stack exchange, up from around 10 on Friday. The offer has already been accepted by the Trolltech BOD."

eldavojohn writes "There has long been speculation on why the Sun's surface is a mere ten thousand degrees while the atmosphere can reach millions. Space.com is reporting that the mystery has now been solved. Researchers looked for Alfven waves in the solar chromosphere and found them. Followup studies employing simulations demonstrated that the energetics work out to transfer energy from the Sun's surface to its overlying corona.. The magnetic waves may also be the power source behind the solar wind."

gazurtoid writes "Astrobiology Magazine is reporting that astronomers have announced a mystery object orbiting the 8-million-year-old brown dwarf 2M1207 170 light-years from Earth might have formed from the collision and merger of two protoplanets. The object, known as 2M1207B, has puzzled astronomers since its discovery because it seems to fall outside the spectrum of physical possibility. Its combination of temperature, luminosity, and age do not match up with any theory. 'Hot, post-collision planets might be a whole new class of objects we will see with the Giant Magellan Telescope', said Eric Mamajek of the Harvard-Smithsonian Center for Astrophysics."

porkpickle tips us to a BBC article on the quasar OJ287, a binary object containing largest black hole yet discovered, weighing in at 18 billion times the mass of Sol. Researchers were able to estimate its mass due to the presence of a smaller black hole in orbit around it. When the smaller companion's orbit intersects OJ287's accretion disk, once every 12 years, it triggers a burst of radiation that was detected by the Spitzer Space Telescope. More detail and a diagram are available on the Turku University site.

Active Seti brings us news that astronomers have discovered the origin of an enormous antimatter cloud surrounding the galactic center. Data from the European Space Agency's "Integral" satellite indicated that the cloud's distribution is similar to that of a group of binary star systems containing black holes or neutron stars. From NASA's article: "The cloud itself is roughly 10,000 light-years across, and generates the energy of about 10,000 Suns. The cloud shines brightly in gamma rays due to a reaction governed by Einstein's famous equation E=mc^2. Integral found that the cloud extends farther on the western side of the galactic center than it does on the eastern side. Integral found certain types of binary systems near the galactic center are also skewed to the west. Because the two "pictures" of antimatter and hard low-mass X-ray binaries line up strongly suggests the binaries are producing significant amounts of positrons."

An anonymous reader writes "Julian Murdoch over at GamersWithJobs.com has what can only be described as a piece of liturgy, proclaiming a religious experience at his local Best Buy as he watches someone beat 'Through the Fire and the Flames' on Expert in Guitar Hero 3. 'At 6 minutes in, a small crowd has formed, perhaps 15 of us. His sravaka — his disciples — look nervously at us, absorbing the distractions, protecting him a bubble of calm. There is complete silence. Even my son is staring slackjawed, like he does in church during communion, not understanding the content of the ritual but understanding the tone and sacredness of the space.'"

wwrmn writes "There's a debate going on over at bugs.launchpad.net on whether it's the Ubuntu, BIOS, hard-drive manufacturer, or pick-any-player's fault, but Ubuntu (and perhaps any OS) may be dramatically shortening the life of your laptop's hard drive due to an aggressive power-saving feature / acpi bug / OS configuration. Regardless of where the fault lies or how it's fixed, you might want to take some actions now to try to prevent the damage."

Esther Schindler writes "Sure, everyone uses technology on the job. But you may not have contemplated the tools used by paranormal investigators (at least, not until you began thinking about Halloween) who look for the truth in ghosts and other things that go Bump in the Night. In Paranormal Investigations and Technology: Where Ghosts and Gadgets Meet, CIO's Al Sacco writes about the most unusual of tool chests, with everything from thermometers to blimp cams." You want spooky? An anonymous reader passed a link to a survey that says a third of Americans believe in ghosts. Who you gonna call?

Russ Nelson writes "In a board meeting held October 10th and announced today, the Open Source Initiative approved two of Microsoft's software licenses: the Microsoft Reciprocal License and the Microsoft Public License. These licenses are refreshingly short and clean, compared to, say, the GPLv3 and the Sun CDDL. They share a patent peace clause, a no-trademark-license clause, and they differ only in the essential clause of reciprocation. Of course, Microsoft is not widely trusted in the Open Source world, and their motives have been called into question during the approval discussions. How can they be attacking Open Source projects on one hand, and seeking not only to use open source methods, but even to use the OSI Approved Open Source trademark? Nobody knows for sure except Microsoft. But if you are confident that Open Source is the best way to develop software (as we at the Open Source Initiative are), then you can see why Microsoft would both attack Open Source and seek to use it. It is both their enemy and their salvation."

Bowling for cents writes "There is evidence that the massive Storm Worm botnet is being broken up into smaller networks, and a ZDNet post thinks that's a surefire sign that the CPU power is up for sale to spammers and denial-of-service attackers. The latest variants of Storm are now using a 40-byte key to encrypt their Overnet/eDonkey peer-to-peer traffic, meaning that each node will only be able to communicate with nodes that use the same key. This effectively allows the Storm author to segment the Storm botnet into smaller networks. This could be a precursor to selling Storm to other spammers, as an end-to-end spam botnet system, complete with fast-flux DNS and hosting capabilities."

Geoffrey.landis writes "It was only a small news item four months ago: all three of the Russian computers that control the International Space Station failed shortly after the Space Shuttle brought up a new solar array. But why did they fail? James Oberg, writing in IEEE Spectrum, details the detective work that led to a diagnosis." The article has good insights into the role the ISS plays as a laboratory for US-Russian technology cooperation — something that is likely to be crucial in any manned Mars mission.

you-bet-it's-not-out-of-context writes "A blogger on KDE Developer's Journal has found an interesting post by Miguel de Icaza, the founder of GNOME and Mono, in a Google group dedicated to the discussion of his blog entries. Six days ago Miguel stated that 'OOXML is a superb standard and yet, it has been FUDed so badly by its competitors that serious people believe that there is something fundamentally wrong with it.' In the same post he says that to avoid patent problems over Silverlight, when using or developing Mono's implementation (known as Moonlight), i's best to 'get/download Moonlight from Novell which will include patent coverage.'"

Several readers tipped us the followup of yesterday's AMD/ATI news, the new development hinted at by Phoronix: AMD has announced they are releasing the specs for all new Radeon chipsets, and will be working with the open source community to develop a fully functional 2D and 3D graphics driver. An anonymous reader opines: "AMD appears to be following in Intel's footsteps with upcoming releases. If AMD is successful NVidia will have real competition in the GNU/Linux gaming arena. While past support by ATI was unsatisfactory the new AMD buyout appears to be having some effect."
