Comment So what is the explanation? (Score 1) 56

From looking at TFA what I garner is that galaxies got arms a long time ago "as they got older". Specifically: "Then the clumps elsewhere in the glalxy (sic) begin to smear out forming woolly, indistinct arms." Nailing down the process, they follow with "More complex structures follow later." Wow, mystery solved. Now I seem to remember some research 10 or so years ago that showed through computer simulations that 2 galaxies composed of homogeneous distributions of stars, if they pass relatively close to each other at speed, will affect each other and cause each one to form spiral arms. That made intuitive sense, backed up with data. This article... really... what does this article say?

Petaflops? DARPA Seeks Quintillion-Flop Computers 185

coondoggie writes "Not known for taking the demure route, researchers at DARPA this week announced a program aimed at building computers that exceed current peta-scale computers to achieve the mind-altering speed of one quintillion (1,000,000,000,000,000,000) calculations per second. Dubbed extreme scale computing, such machines are needed, DARPA says, to 'meet the relentlessly increasing demands for greater performance, higher energy efficiency, ease of programmability, system dependability, and security.'"

Activision Hit With $500m Suit From Modern Warfare 2 Devs 77

Dragoniz3r writes "Activision has been served a lawsuit from 38 plaintiffs, including present and former Infinity Ward employees, demanding up to half a billion dollars. The plaintiffs are seeking compensation for 'unpaid bonuses, royalties, profit-sharing, and future profits from games such as Modern Warfare 3, and punitive damages.'"

Computer Vision Tech Grabs Humans In Real-Time 3D 110

Tinkle writes "Toshiba's R&D Labs in Cambridge, UK have developed a system capable of real-time 3D modeling of the human face and body — using a simple set of three different colored lights. Simple it may be, but the results are impressive. Commercial applications for computer vision technology look set to be huge — according professor Roberto Cipolla. On the horizon: cheap and easy digitized everyday objects for ecommerce, plus gesture-based interfaces — a la Natal — and in-car safety systems. Ultimately even driver-less cars. 'This is going to be the decade of computer vision,' predicts Cipolla."

Is Mimas Hiding Pac-Man? 99

cremeglace writes "Shaped into the likes of the Death Star of Star Wars fame by the giant crater Herschel, 396-kilometer-diameter Mimas was expected to have its warmest surface temperatures on the equator, where it was early afternoon. Instead, it was warmest in the morning (all of 92 K), giving rise in the science team's temperature-calibrated color scheme to a very large Pac-Man."

An Early Look At Civilization V 286

c0mpliant writes "IGN and Gamespot have each released a preview of the recently announced and eagerly awaited Civilization V. Apart from the obvious new hexagon shape of tiles and improved graphics, the articles go on to outline some of the major changes in the game, such as updated AI, new 'flavors' to world leaders, and a potentially game-changing, one-unit-per-tile system. No more will the stack of doom come to your city's doorsteps. Some features which will not be returning are religion and espionage. The removal of these two have sparked a frenzy of discussion on fan-related forums."

How Do You Get Users To Read Error Messages? 951

A BOFH writes "The longer I do desktop support, the more it becomes obvious that my users don't read anything that appears on their screen. Instead, they memorize a series of buttons to press to get whatever result they want and if anything unexpected happens, they're completely lost. Error logs help a lot, but they have their limits. I've been toying with a few ideas, but I don't know if any of them will work and I was hoping my fellow Slashdotters could point me in the right direction. For example, I was thinking about creating icons or logos to identify specific errors. They might not remember that an error is about 'uninitialized data' but they might be more able to remember that they got the 'puppy error' if I showed a puppy picture next to the error message. Or for times when finding images is too time consuming, you could create simple logos from letters, numbers, symbols, colors, or shapes, so you could have the 'red 5' error or 'blue square' error (or any combination of those elements). I've even wondered if it would be possible to expand that to cover the other senses, for example, playing a unique sound with the error. Unfortunately, haptic and olfactory feedback aren't readily available. I like to think that my users would remember the error that caused them to get a swift kick in the balls. And if they forgot it anyhow, I could always help them reproduce it. Does anyone else have experience with ideas like these? Did it work?"

NASA Astronauts To Open New Space Station Windows 79

coondoggie writes "After some fancy robotic crane work over the past couple days, NASA Endeavour astronauts are preparing for tonight's final spacewalk where they will open the windows on the space station's sweet new dome-shaped observatory. The cupola observatory module is considered the ultimate observation deck. It is attached to an Earth-facing side of the International Space Station and has seven windows — six around the sides and one on top — that can be shuttered when not in use to protect them from micrometeoroids and the harsh space environment."

Scientists Build a Smarter Rat 302

destinyland writes "Scientists have engineered a more intelligent rat, with three times the memory length of today's smartest rats. Reseachers bred transgenic over-expression of the NR2B gene, which increased communication between the rat's memory synapses. Activating a crucial brain receptor for just a fraction of a second longer produces a dramatic effect on memory, as proven by the rat's longer memories of the path through a maze."

DHS Pathogen Lab To Be Built In "Tornado Alley" 275

Hugh Pickens writes "The Washington Post reports that Department of Homeland Security is relying on a rushed, flawed study to justify its decision to locate the $700 million National Bio and Agro-Defense Facility for highly infectious pathogens in a tornado-prone section of Kansas. A GAO report says that it is not 'scientifically defensible' to conclude that lab can safely handle dangerous animal diseases in Kansas. Such research has been conducted up to now on a remote island on the northern tip of Long Island, NY. 'Drawing conclusions about relocating research with highly infectious exotic animal pathogens from questionable methodology could result in regrettable consequences,' the GAO warned in its draft report. Critics of moving the operation to the mainland argue that a release could lead to widespread contamination that could kill livestock, devastate a farm economy, and endanger humans. Along with the highly contagious foot-and-mouth disease, NBAF researchers plan to study African swine fever, Japanese encephalitis, Rift Valley fever, and other viruses in the Biosafety Level (BSL) 3 and BSL-4 livestock laboratory capable of developing countermeasures for foreign animal diseases. According to the article, DHS lobbied a Congressional committee to try and convince them that the GAO report was flawed, and to head off any hearings on the controversy. Despite this, the House Energy and Commerce Committee's oversight and investigations subcommittee plans to hold a hearing Thursday on the risk analysis."

Reprogrammed Skin Cells Turned Into Baby Mice 284

InfiniteZero writes "According to this WSJ story, 'Two teams of Chinese researchers working separately have reprogrammed mature skin cells of mice to an embryonic-like state and used the resulting cells to create live mouse offspring. The reprogramming may bring scientists one step closer to creating medically useful stem-cell lines for treating human disease without having to resort to controversial laboratory techniques. However, the advance poses fresh ethical challenges because the results could make it easier to create human clones and babies with specific genetic traits.'"
