eldavojohn writes "Dr. Adam Maloof has found fossils of sea sponges in Australia from 650 million years ago. You might think this is no big deal unless you consider that sea sponges were thought to have arisen 520 million years ago. These fossils predate the oldest hard bodied fossils we have by a hundred million years. Dr. Maloof is now wondering if life might have arisen twice after the first attempt was quashed 635 million years ago: 'Since animals probably did not evolve twice, we are suddenly confronted with the question of how some relative of these reef-dwelling animals survived the Snowball Earth.' So how is it that life survived the Marinoan glaciation? The BBC has a video on the topic and Wikipedia has a time line of the Proterozoic Eon into the Paleozoic Era."

nk497 writes "To see one of the 32nm transistors on an Intel chip, you would need to enlarge the processor to beyond the size of a house. Such extreme scales have led some to wonder how much smaller Intel can take things and how long Moore's law will hold out. While Intel has overcome issues such as leaky gates, it faces new challenges. For the 22nm process, Intel faces the problem of 'dark silicon,' where the chip doesn't have enough power available to take advantage of all those transistors. Using the power budget of a 45nm chip, if the processor remains the same size only a quarter of the silicon is exploitable at 22nm, and only a tenth is usable at 11nm. There's also the issue of manufacturing. Today's chips are printed using deep ultraviolet lithography, but it's almost reached the point where it's physically impossible to print lines any thinner. Diffraction means the lines become blurred and fuzzy as the manufacturing processes become smaller, potentially causing transistors to fail. By the time 16nm chips arrive, manufacturers will have to move to extreme ultraviolet lithography — which Intel has spent 13 years and hundreds of millions trying to develop, without success."

dwguenther writes "A Lyons (Colorado) area woman with no academic pedigree has published a scientific paper in the International Journal of Forestry Research about the adverse effects of radio waves on aspen seedlings. Katie Haggerty, who lives north of Steamboat Mountain, found in a preliminary experiment done near her house that aspens shielded from electromagnetic radiation were healthier than those that were not. 'I found that the shielded seedlings produced more growth, longer shoots, bigger leaves, and more total leaf area. The shielded group produced 60 percent more leaf area and 74 percent more shoot length than a mock-shielded group,' she said." This was not a definitive study, as its author readily admits — it's hard to see how a double-blind study could even be designed in this area — but it was refereed.

ThinkGeek, sister company to Slashdot, received a meticulously researched (except on one point) 12-page cease-and-desist letter from the National Pork Board. What had the meat lobbyists up in arms was an April Fools product from the TG catalog: Radiant Farms Canned Unicorn Meat, whose copy included the line "the new white meat." The NPB figured this was confusingly similar to their trademarked "the other white meat" (an advertising slogan the pork industry is considering retiring anyway). Geeknet, parent company of Thinkgeek and Slashdot, issued a press release apologizing for any confusion; you can read it on ThinkGeek's site (PDF), because the newswires refused to distribute it for some reason. Oh, and ThinkGeek has no intention of taking down the protected parody.

crimeandpunishment sends along this snip from an AP story carried on Skunkpost.com: "High tech means low crime in a New Jersey city that has used an arsenal of advanced technology to sharply lower one of the highest crime rates in the nation. And now East Orange is poised to become the first city in the country to take high tech crime fighting to a whole new level ... surveillance cameras with sensors that can be programmed to identify crimes as they unfold."

With the advent of the Wii and the upcoming motion control systems from Sony and Microsoft, console makers are expanding the gaming population to include vast numbers of casual players. Their problem now, according to this editorial at Eurogamer, is that there doesn't exist a broad selection of games between the simple, introductory titles and the complex, hardcore ones, which tends to limit how deep new players will venture into the gaming ecosystem. Quoting: "... it needs software that spans the gap between the two camps of offerings which are emerging on Xbox 360 — games that encourage players of Dance Central or Your Shape to move upstream and explore. It's unlikely, perhaps, that they'll ever end up curb-stomping crinkle-faced nasties in Cliff Bleszinski's latest, but we're a long way past the point of the Xbox being all about shooting and driving, even if the public perception hasn't quite moved with the software line-up. The long-term challenge for the games market must, ultimately, be to emulate the success which other mediums have had in creating markets where consumers routinely and happily move between genres, and where franchises which would be pigeonholed as 'hardcore' in the games world nestle comfortably in people's DVD collections alongside those which would be dismissed as 'casual.'"

The Bad Astronomer writes "A rumor is spreading on the Net like wildfire that the red supergiant star Betelgeuse is about to explode in a supernova. This rumor is almost certainly not true. First, it's posted on a doomsday forum. Second, it's three times removed from the source, and is anonymous at each step. Third, the evidence is shaky at best. Plus, even if true, the supernova is too far away to hurt us. But other than that ..."

Tumbleweed writes "How to make Steve Jobs your mortal enemy: Smokescreen, a 175KB, 8,000-line JavaScript-based Flash player written by Chris Smoak at RevShock, a mobile ad startup, and to be open-sourced 'in the near future.' From Simon's blog: 'It runs entirely in the browser, reads in SWF binaries, unzips them (in native JS), extracts images and embedded audio, and turns them into base64 encoded data: URIs, then stitches the vector graphics back together as animated SVG. ... Smokescreen even implements its own ActionScript bytecode interpreter.' Badass!"

sciencehabit writes "Science answers the question: What happens when you put a snail on speed? From the article: 'The results suggest that meth improves memory, something that has been previously observed in creatures with large, complex brains like rats and humans. But since the snails store their memories in a simple, three-neuron network, the team hopes that studying the meth effect in these gastropods will help pinpoint how the drug's memory magnification powers work.'"

jerryjamesstone writes "Everybody is into rail these days; it is the greenest way to get around next to a bike. Leonid Mulyanchik has been into it for years since before the Berlin Wall fell, since before the first Macintosh, building his own private underground Metro railway system. English-Russia says that he has been doing it with his pension, that it is all legal and approved and that he is still at it. Gizmodo calls it 'Partly the traditional, inspiring, one man against all odds type of persistence, but more the obsessive, borderline insane persistence.'" Update: 06/02 07:33 GMT by T : And if you're the type to visit Burning Man, you can actually ride a home-made monorail this summer, too.

An anonymous reader writes "According to this IEEE story, iRobot and the US military have released video showing a weaponized version of iRobot's Warrior robot. In the video, the Warrior is seen firing a weapon system called the APOBS (Anti-Personnel Obstacle Breaching System), a grenade-filled line propelled by a rocket and stabilized by a drogue parachute. This system is used to clear minefields and obstructed roads. The video shows soldiers deploying a Warrior with the APOBS mounted on its back. The robot fires the device, which lands along a dirt road, exploding after a few seconds. A voice is then heard, 'Road clear; proceed forward.'"

krou writes "Junior students at Higher Lane Primary in Whitefield, Greater Manchester, are in a trial of a system that uses their thumbprints to check out and return books from a library. The thumbprints are 'digitally transformed into electronic codes, which can then be recognized by a computer program.' The system was developed by Microsoft, and is being trialled elsewhere in the country. NO2ID condemned the system, saying it was appalling, and that 'It conditions children to hand over sensitive personal information.' The headmaster has defended the scheme, saying, 'We have researched this scheme thoroughly. It is a biometric recognition system and no image of a fingerprint is ever stored. It is a voluntary system. The thumbprint creates a mathematical template. All parents have been written to and we have told them what the system is all about. From the responses we have had there has been overwhelming support. We hold a lot of information about children because we are a school. This is no different.'"
