cremeglace writes "Astrophysicists have found that when a supermassive black hole quickly devours gas and dust, it can generate enough radiation to abort all the embryonic stars in the surrounding galaxy. It's not clear what this means for life's ability to take hold in such a bleak environment, but the research shows that the process might have determined the fates of many of the large galaxies in the universe."

ectotherm writes "By 2018, the US Navy hopes to equip its fighter jets with the ability to shoot data streams containing 'specialized waveforms and algorithms,' useful in an electronic attack or cyber-invasion. A few non-classified details here."

astroengine writes "NASA's Spitzer Space Telescope had the unprecedented opportunity to observe the heart of the Orion Nebula for 40 days, returning 80 images of the star-forming region. In doing so, the observatory has been keeping track of 1,500 young stars as they undergo rapid variations in brightness, caused by large 'cool spots' on the surface of the stars and obscuring dust. However, the high resolution images Spitzer is returning take center-stage, showing a tight cluster of stellar birth amid the nebulous clouds of dust. This is an incredible achievement considering its primary mission is over (after using up all of its liquid helium coolant in May 2009) and only two instruments are still working."

coondoggie writes "Despite the daily drumbeat of new and improved hardware or software, the tech industry isn't all bits and bytes. Some interesting things happen along the way too. Like floating data centers, space geekonauts, shape shifting robots and weird bedfellows (like Microsoft and Jerry Seinfeld). What we include here is an example of what we thought were the best, slightly off-center stories of 2008."

theodp writes "Barack Obama supporters were left shaking their heads after a report surfaced that the president-elect was using a Zune at the gym instead of an iPod. So why would Mac-user Obama be Zune-ing out? Could be one of those special-edition preloaded Zunes that Microsoft bestowed on Democratic National Convention attendees, suggests TechFlash, nixing the idea that the soon-to-be Leader of the Free World would waste time loading Parallels or Boot Camp in OS X just to use a Zune."

nandemoari writes "Remember the 1991 film, 'The Rocketeer,' where a young pilot uses a jetpack prototype to become a masked vigilante and win the heart of Jennifer Connelly? That scenario isn't as far-fetched as it once was, given that an American stuntman recently used a jetpack to soar over Colorado's Royal Gorge. The stuntman in question is one Eric Scott, who recently appeared on CBS' Early Show and a variety of local cable channels after making his daring leap. Scott has been testing jetpack devices for 16 years, and was confident that he wouldn't plummet to his untimely death when he straddled the Gorge above the Arkansas River earlier this week. Despite an enormous gulf between the two sides — 1,500 feet across and 1,000 feet down — Scott made the trip safely."

p1234 writes with this excerpt from the Max Planck Institute for Astrophysics: "Simulations by the Virgo team show how the Milky Way's halo grew through a series of violent collisions and mergers from millions of much smaller clumps that emerged from the Big Bang. ... If Fermi does detect the predicted emission from the Milky Way's smooth inner halo, then it may, if we are lucky, also see gamma-rays from small (and otherwise invisible) clumps of dark matter which happen to lie particularly close to the Sun. ... The largest simulation took 3.5 million processor hours to complete. Volker Springel was responsible for shepherding the calculation through the machine and said: 'At times I thought it would never finish.' Max Planck Director, Professor Simon White, remarked that 'These calculations finally allow us to see what the dark matter distribution should look like near the Sun where we might stand a chance of detecting it.'" We discussed a related simulation a few months ago.

xyz writes "NASA's Fermi Gamma-ray Space Telescope has discovered a new class of pulsars which emit purely in gamma rays. A pulsar is a rapidly spinning neutron star, and of the nearly 1,800 cataloged so far, only a small fraction emit at frequencies higher than radio waves. The gamma-ray-only pulsar, which lies within a supernova remnant known as CTA 1, is silent across parts of the electromagnetic spectrum where pulsars are normally found, indicating a new class of pulsars. It is located 'about 4,600 light-years away in the constellation Cepheus. Its lighthouse-like beam sweeps Earth's way every 316.86 milliseconds. The pulsar, which formed in a supernova explosion about 10,000 years ago, emits 1,000 times the energy of our sun.'"

Wired reports on the Enriched Xenon Observatory 200, a particle detector scientists hope will answer the question of why there is significantly more matter than antimatter in the universe. Quoting: "The new detector will try to fill in the picture, determining basic features of [neutrinos], like their mass and whether or not they, unlike almost all other particles, are their own antiparticles. That quirk is why some scientists believe neutrinos could be the mechanism for the creation of our matter-filled universe. Almost all other particles have an antiparticle twin that, if it comes into contact with the particle, immediately annihilates it. But if neutrinos are their own antiparticles they could conceivably be knocked onto matter's 'team,' thereby causing the cascading win for matter over antimatter that we know occurred. As the Indian theoretical physicist G. Rajasekaran put it in a speech [PDF] earlier this year, neutrinos that are their own antiparticles would explain 'how, after [the] annihilation of most of the particles with antiparticles, a finite but small residue of particles was left to make up the present Universe.'"

Ostracus writes "The latest request from the Pentagon jars the senses. At least, it did mine. They are looking for contractors to 'develop a software/hardware suite that would enable a multi-robot team, together with a human operator, to search for and detect a non-cooperative human subject. The main research task will involve determining the movements of the robot team through the environment to maximize the opportunity to find the subject ... Typical robots for this type of activity are expected to weigh less than 100 Kg and the team would have three to five robots.'" To be fair, they plan to use the Multi-Robot Pursuit System for less nefarious-sounding purposes as well. They note that the robots would "have potential commercialization within search and rescue, fire fighting, reconnaissance, and automated biological, chemical and radiation sensing with mobile platforms."

Andrew Moseman writes "Part of the trouble NASA is encountering while fixing the Hubble Space Telescope comes from the fact that it's been up there for nearly two decades, and therefore carries computer systems long outdated here on Earth. 'One of the main computers that the Goddard team has been struggling with during the repair attempts runs on an Intel 486 chip, the height of 1989 technology.' Many of NASA's long-running missions rely on antiquated systems — the Voyager probes each have about 32k of memory — but the scientists say they can manage."

Oprah Winfrey enthused about the Amazon Kindle on her show today — it's her "new favorite thing" — and had Jeff Bezos on to announce a $50-off offer good till Nov. 1. A plug on Oprah is ordinarily a sign that a product has crossed over into the mainstream. But her show's audience has been slipping lately, and it's unclear how many cash-strapped citizens will be willing to part with $309 (after the special offer) for a new techno-gadget, for which they then have to shell out more money for DRM-encrusted content.

trackpick points out a recent ACLU initiative to publicize a recent expansion of authority claimed by the Border Patrol to stop and search individuals up to 100 miles from any US border. They have created a map of what they call the US Constitution-Free Zone. "Using data provided by the US Census Bureau, the ACLU has determined that nearly 2/3 of the entire US population (197.4 million people) live within 100 miles of the US land and coastal borders. The government is assuming extraordinary powers to stop and search individuals within this zone. This is not just about the border: This 'Constitution-Free Zone' includes most of the nation's largest metropolitan areas.'"

niktemadur writes "The BBC reports that a French team of stellar seismologists, using the COROT Space Telescope, have converted stellar oscillations into sound patterns, a relatively new technique that, according to Professor Eric Michel of the Paris Observatory, is already giving researchers new insight into the inner workings of stars. The subtly pulsating, haunting sounds are very similar to artist Aphex Twin's minimalistic nineties album 'Selected Ambient Works, Vol. 2,' only stripping away what little melody it had and leaving just the beat. These and many more recordings from space can be accessed at the Jodrell Bank Center for Astrophysics website, also known as the Jodcast."

ptorrone writes "Lots of open source hardware articles making the rounds this week, first up — Wired has an excellent piece on the Arduino project, an open source electronics prototyping platform, its founders and business model (they have sold over 50,000 units). And next up MIT's Tech Review has a profile on a few open source hardware businesses including NYC based Adafruit Industries best known for projects like the open source synth (x0x0b0x) and 'fun' projects like the Wave Bubble, the open source cell phone/wifi/GPS/RF jammer."
