Submission + - OLE, the fire fighting beetle (gearfuse.com)

bob82 writes: "Researchers are working on OLE, a new autonomous robot that could one day help out putting out fires. This fire fighting beetle will be programmed to run through the forest at 20 to 30 km per hour, looking for potential forest fires in the works and extinguishing them with an impulse appliance."

Steve Jobs Hates Buttons 713

ElvaWSJ writes "While many technology companies load their products up with buttons, Steve Jobs treats them as blemishes that add complexity and hinder their clean aesthetics. The iPhone is Steve Jobs's attempt to crack a juicy new market for Apple Inc. But it's also part of a decades-long campaign by Mr. Jobs against a much broader target: buttons. The new Apple cellphone famously does without the keypads that adorn its rivals. Instead, it offers a touch-sensing screen for making phone calls and tapping out emails. The resulting look is one of the sparest ever for Apple, a company known for minimalist gadgets. "

Humans Evolved From a Single Origin In Africa 461

Invisible Pink Unicorn writes "Researchers at the University of Cambridge have combined studies of global human genetic variations with skull measurements worldwide to show conclusively the validity of the single origin hypothesis. The alternative hypothesis contended that different populations independently evolved from Homo erectus to Home sapiens in different areas. The lead researcher explains, 'The origin of anatomically modern humans has been the focus of much heated debate. Our genetic research shows the further modern humans have migrated from Africa, the more genetic diversity has been lost within a population. However, some have used skull data to argue that modern humans originated in multiple spots around the world. We have combined our genetic data with new measurements of a large sample of skulls to show definitively that modern humans originated from a single area in Sub-saharan Africa.' The article abstract is available from Nature."

Dark Energy May Lurk In Hidden Dimensions 164

Magdalene writes in to let us know about a sketch of an idea, that might one day become a theory, to explain the dark energy that is making the universe flee faster and faster apart. It posits that dark energy may be the result of a new kind of neutrino wandering in tiny extra dimensions above our familiar three. She adds, "There is no word yet on whether Sphere or Square are available for comment." From the article: "The mysterious cosmic presence called dark energy, which is accelerating the expansion of the universe, might be lurking in hidden dimensions of space. This idea would explain how the dimensions of space remain stable — one of the biggest problems for the unified scheme of physics called 'string theory'... To get the same amount of acceleration seen by astronomers, Greene and Levin calculate that the extra dimensions should have a scale of about 0.01 millimeter."

Politically Incorrect Observations About Human Nature 613

gsa writes "Why do men prefer blonds? Why are most suicide bombers Muslim? Psychology Today analyzes some of these non-politically-correct questions in this essay about ten politically-incorrect truths about human nature. It turns out there may be an evolutionary or psychological explanation for all of these observations. For example, 'Sociologists and demographers have discovered that couples who have at least one son face significantly less risk of divorce than couples who have only daughters. Why is this? ... There is relatively little that a father (or mother) can do to keep a daughter youthful or make her more physically attractive. The continued presence of (and investment by) the father is therefore important for the son, but not as crucial for the daughter. The presence of sons thus deters divorce and departure of the father from the family more than the presence of daughters, and this effect tends to be stronger among wealthy families.'"

Half-Squid, Half-Octopus Discovered Off of Hawaii 170

Otter writes "A unique creature that's been dubbed an 'octosquid' with eight arms and a squid-like mantle, was discovered off Hawaii. The creature, of a previously unknown species, was trapped in the net covering a 3,000 foot-deep intake tube for the Natural Energy Laboratory of Hawaii Authority. From the article: 'The octosquid was pulled to the surface, along with three rattail fish and half a dozen satellite jellyfish, and stayed alive for three days. According to War, the lab usually checks its filters once a month, but this time, it put a plankton net in one of the filters and checked it two weeks later. The pitch-black conditions at 3,000 feet below sea level are unfamiliar to most but riveting to scientists who have had the opportunity to submerge. The sea floor is full of loose sediment, big boulders and rocks, and a lot of mucuslike things floating in the water, which are usually specimens that died at the surface and drifted to the bottom.'"

Blizard Sues Virtual Gold Seller 242

DaphneDiane writes "Blizzard announced that they are suing one of the heavily spamming gold sellers, Peons4hire. Peons4hire had recently been spamming players in World of Warcraft with multi-line messages advertising their power leveling and gold selling business. With the advent of the recently released 2.1.0 patch Blizzard made it easier to report and block these spammers. I've noticed a large decrease in spam while playing since the patch. It used to be that I would get nearly a dozen spams a night but I barely have seen any since."

LinuxBIOS Gets GUI 171

LWATCDR writes "Has a great write up on combining LinuxBios a Linux kernel, busybox, X, a window manager, and rxvt into a two meg flash chip. So what does get you? A six second boot time for one. All sorts of uses come to mind. Terminals to use with the Linux Terminal server. A very fast booting embedded system like a Car computer. With every one pushing for multi-core cpus, mega gigabyte drives and many gigabytes of ram it is interesting to see how small you can go."

The Coevolution of Lice & Their Hosts 179

eldavojohn writes "It might be an uncomfortable subject but parasites are an interesting subject when it comes to evolution. Ever wonder if pocket gophers have lice? Well, they do. And most interesting of all is the evolution of these lice mirroring the evolution of gophers. To study the genes of lice may shed just as much light on evolutionary trees as studying the genes of the actual host the lice has evolved to. The most unsettling result from these studies is that human head lice and human pubic lice (crabs) vary so greatly that they are in two separate genera. There were similarities between our pubic lice and the lice found on gorillas. Scientists came to the conclusion, which they published today in BMC Biology, is just as striking as their earlier one about head lice. But it is hardly the same. We did not get pubic lice from other hominids. We got them from the ancestors of gorillas."

Ruby Implementation Shootout 112

An anonymous reader writes "Ruby has an ever growing number of alternative implementations, and many of these attempt to improve the suboptimal performance of the current mainstream interpreter. Antonio Cangiano has an interesting article in which he benchmarks a few of the most popular Ruby implementations, including Yarv (the heart of Ruby 2.0), JRuby, Ruby.NET, Rubinius and Cardinal (Ruby on Parrot). Numerical evidence is provided rather than shear opinions. The tests show that Yarv is the fastest implementation and that it offers a promising future when it comes to the speed of the next Ruby version."

NASA to Launch Magnetic Storm Probes 51

eldavojohn writes "The aurora borealis (also known as the Northern Lights) has long been known to be an effect resulting from the Sun's solar wind pushing particles into the earth's magnetic field and atmosphere. In light of the possible danger that these substorms could pose to astronauts & equipment, NASA is now planning a mission to track down these magnetic storms and disturbances. The program's not so catchy name of Time History of Events and Macroscale Interaction during Substorms has a slightly catchier acronym of THEMIS. From the article, "In order to scan the Earth's magnetic field and pinpoint the origin of substorms, THEMIS researchers plan to stagger their spacecraft in different orbits that range in altitude from 10 to 30 times the radius of the Earth (the planet's radius is about 3,962 miles, or 6,378 kilometers).""

A Hands-On Zune Review 279

jayintune writes "2old2play.com got the chance to sit down with Microsoft's new media player, the Zune, to give some comments and insight into the players User Interface, Video Playback, Music Sharing, as well as software and setup." From the article: "I had expected the player to be fairly heavy, but after holding the Zune in my hand it was clear that I was wrong. It is not as light as the latest video iPod, but compared to my fourth-generation iPod, the Zune was lighter. The top of the Zune had a clear glass layer while the exterior had a tactile feel to it, nothing like the hard metal and plastic of the iPod devices. The 'skin' of the Zune was a 'rubberized' material that had a smooth seductive feel to it. I found myself unable to stop stroking the device, so much that the demo assistant asked me to put it down."

smcFanControl — Cool Your MacBook Pro 195

Clodas writes, "smcFanControl 1.1 is a simple GUI that lets you control how fast each fan spins on your MacBook, MacBook Pro, or Mac Mini. The temperature of my MBP when idle averaged around 63 degrees celsius. After running smcFanControl 1.1, my temperature dropped to 43 celsius within 10 minutes of use. This now allows me to sit my MBP on my lap, something I was unable to do previously since the machine got so hot. I have my fans set to spin at a minimum of 3000 RPM and I still don't hear the fans spinning. Apple by default has them set to 1000 RPM. I really recommend smcFanControl 1.1 for any that feel their MB, MBP, or Mini are too hot to handle."
