What Makes Spider Webs Tough As Steel 76

sciencehabit writes "A new analysis reveals the intricacies of spider web design, showing how the unique properties of its silk turn webs into flexible yet strong traps. Computer simulations reveal that heavy forces spread over the entire net rather than stay local. Real spider silk can be either stretchy or stiff at different times, which produces threads that flex and then snap in just the right way to avoid wrecking nearby spokes."

Early Plants May Have Caused Massive Glaciation 174

sciencehabit writes with this excerpt from Science: "The first plants to colonize land didn't merely supply a dash of green to a drab landscape. They dramatically accelerated the natural breakdown of exposed rocks, according to a new study, drawing so much planet-warming carbon dioxide (CO2) from the atmosphere that they sent Earth's climate spiraling into a major ice age."

USPTO Declares Invalid Third of Three Critical Rambus Patents 113

slew writes "This is a followup to this earlier story about 2 of 3 of Rambus's 'critical' patents being invalidated. Apparently now it's a hat-trick." There's something that seems unsavory and wasteful about a business environment in which a company's stock value "fluctuates sharply on its successes and failures in patent litigation and licensing." The linked article offers a brief but decent summary of the way Rambus has profited over the years from these now-invalidated patents.

North Star May Be Wasting Away 129

sciencehabit writes "The North Star, a celestial beacon to navigators for centuries, may be slowly shrinking, according to a new analysis of more than 160 years of observations. The data suggest that the familiar fixture in the northern sky is shedding an Earth's mass worth of gas each year."

HP To Open Source WebOS 137

First time accepted submitter pscottdv writes "This year the artists formerly known as Palm had quite a rough few months with HP dumping the hardware side of their own webOS mobile computing platform – their most recent move, having been announced just last month, is live today: open sourced webOS for all. While the actual main product which will be known as Open webOS 1.0 will not be released until September, they've already got the Enyo piece of the pie available today."

Pwn2Own 2012 Set To Reveal More Browser Vulnerabilities Than In the Past 57

darthcamaro writes "In any given year, Slashdot always has stories about how a researcher hacked a browser in only a few minutes at the Pwn2own hacking challenge. This year the rules are a bit different, and instead of hackers winning for just one vulnerability, the rules allow for multiple vulnerabilities to be presented. The winner isn't the first one to hack a browser, but is the one that can hack the browser the most. 'In the past, due to the way the competition was architected, we had lots of sensationalist headlines, things like "Mac hacked in three seconds,"' said Aaron Portnoy, Manager of the Security Research Team at HP TippingPoint. 'We don't think that type of sensationalism was representative of all the research that was going on.'"

'Electric Earth' Could Explain Planet's Rotation 153

sciencehabit writes "When it comes to Earth's rotation, you might think geophysicists have pretty much everything figured out. Not quite. In order to explain some variations in the way our planet spins, Earth's mantle — the layer of hot, softened rock that lies between the crust and core — must conduct electricity, an ability that the mantle as we know it shouldn't have. Now, a new study (academic paper) finds that iron monoxide, which makes up 9% of the mantle, actually does conduct electricity just like a metal, but only at temperatures and pressures found far beneath the surface."

Is Climate Change the New Evolution? 1055

sciencehabit writes "Is climate change education the new evolution, threatened in U.S. school districts and state education standards by well-organized interest groups? A growing number of education advocates believe so, and yesterday, the National Center for Science Education in Oakland, California, which fights the teaching of creationism, announced that it's going to take on climate change denial as well."

Scientists Create World's Tiniest "Ear" 64

sciencehabit writes "If you've ever wondered what a virus sounds like, or what noise a bacterium makes when it moves between hosts, you may soon get your chance to find out. Scientists have created the world's tiniest ear. The 'nano-ear,' a microscopic particle of gold trapped by a laser beam, can detect sound a million times fainter than the threshold for human hearing. Researchers suggest the work could open up a whole new field of 'acoustic microscopy,' in which organisms are studied using the sound they emit."

Navy May Use Mine-Detecting Dolphins In the Straight of Hormuz 204

New submitter cervesaebraciator writes "The Atlantic Wire reports that the Navy has a tested solution to the possible mining of the Strait of Hormuz. The Navy has 80 dolphins in San Diego Bay trained to use their own sonar to detect mines. When they find the mines, the dolphins drop an acoustic transponder nearby, so that human divers might return to defuse it. Retired Adm. Tim Keating cannot say, however, whether the dolphins will be used in the Straight." The Obama administration has reportedly warned Iran that closing the Strait would provoke an American response.

IBM Tops "Most Patents List" For 19th Straight Year 47

bednarz writes "IBM retained its patent crown for 2011, topping the list of patent winners for the 19th year in a row. The only other U.S. company to make the top 10, Microsoft, fell from third place to sixth place, according to IFI Claims Patent Services' list of the top 50 U.S. patent assignees. HP and Intel fell out of the top 10 and landed 14th and 16th, respectively. Apple moved up to No. 39 after breaking into the top 50 for the first time last year. Asian firms account for 25 of the top 50, and U.S. firms hold 17 slots."

Tracking Down the First Oxygen Users 109

sciencehabit writes "None of us would be here today if, billions of years ago, a tiny, single-celled organism hadn't started using oxygen to make a living. Researchers don't know exactly when this happened, or why, but a team of scientists has come closer than ever before to finding out. They've identified the earliest known example of aerobic metabolism, the process of using oxygen as fuel. The discovery may even provide clues as to where the oxygen came from in the first place."

New CO2 Harvester Could Help Scrub the Air 368

sciencehabit sends this excerpt from ScienceNOW: "Researchers in California have produced a cheap plastic capable of removing large amounts of carbon dioxide (CO2) from the air. Down the road, the new material could enable the development of large-scale batteries and even form the basis of 'artificial trees' that lower atmospheric concentrations of CO2 in an effort to stave off catastrophic climate change."

Video Games As Propaganda 251

SharkLaser writes "A video game developer working for Kuma Reality Games has admitted that the company has been receiving money from the CIA to design and freely distribute special movies and games with the aim of manipulating public opinion in the Middle East. Amir Mizra Hekmati, a former U.S. Marine, moved to work for Kuma after working for DARPA and has said the goal of the company was to convince people that whatever the U.S. does in other countries is a good measure. Kuma officials have declined to comment, while Hekmati himself is locked in Iran. The United States government has demanded the release of Hekmati, but Iran has sentenced him to death for spying, which he confessed to."

NetApp, Lenovo Raise Prices, Citing Thailand Flooding Effects 96

Lucas123 writes "First HP, then EMC, and now NetApp has hiked up the price of its hard disk drives by 5% to 15%. The vendors sent letters to users stating that the flooding in Thailand had caused major component shortages, and while they tried to absorb the supplier price increases, each had to eventually give in. Lenovo also announced it has run out of certain drives for its PC systems including some popular 7,200rpm models."

A Whale's Virtual Reality 21

sciencehabit writes "A surfacing whale is a sight to see, but it would be even more dramatic to watch one ply the ocean depths. Researchers have taken a step closer to doing just that with sophisticated radio-tagging technology and a new computer program that uses the data to recreate a whale's path underwater. The results, which look a bit like a whale riding a roller coaster (see video), are helping scientists understand how the school bus-sized beasts are able to take in enough food to sustain their great girth, and how underwater noises, such as sonar, might affect their well-being."

Is the Canadian Arctic the Future of Astronomy? 106

sciencehabit writes "Frigid temperatures, dry air, and endless nights should, in theory, make the polar regions top spots for ground-based optical astronomy. So far, Antarctica has been getting all the action, with a handful of optical telescopes peering into the sky from the icy continent. But a new study indicates that the Canadian high Arctic is also a good spot for ground-based optical astronomy. In fact, the great white north offers some practical advantages over the Antarctic."

Rare Moon Mineral Found On Earth 64

sciencehabit writes "A mineral previously known only from moon rocks and lunar meteorites has now been found on Earth. Researchers discovered the substance — dubbed tranquillityite after the Sea of Tranquility, where Apollo 11 astronauts landed on the Moon in July 1969— at six sites in Western Australia (abstract). The mineral occurs only in minuscule amounts and has no economic value, but scientists say it could be used for age-dating the rocks in which it occurs."

Insiders Call HP's WebOS Software Fatally Flawed 191

Hugh Pickens writes "Some of the people involved in creating WebOS, the HP TouchPad's core software, now say the product never had a fighting chance because it relied on WebKit, an open-source software engine used by browsers to display Web pages, that just didn't have the horsepower to run fast enough to be on par with the iPhone. 'Palm was ahead of its time in trying to build a phone software platform using Web technology, and we just weren't able to execute such an ambitious and breakthrough design,' says Paul Mercer, who oversaw the interface design of WebOS and recruited crucial members of the team. 'Perhaps it never could have been executed because the technology wasn't there yet.' Another problem was the difficulty in finding programmers who had a keen understanding of WebKit as Apple and Google snatched up most of the top talent including Matias Duarte, vice president of human interface and user experience for WebOS, who left for Google a month after HP's acquisition of Palm. 'When he left, the vacuum was just palpable. What you're seeing is frankly a bunch of fourth- and fifth-stringers jumping onto WebOS in the wake of Duarte's leaving.' CEO Meg Whitman has announced that HP will release the WebOS code for anyone to use, similar to Google's open-source strategy with Android, but some say WebKit will still leave WebOS underpowered relative to Apple's software."

How the Year Looked On Slashdot 161

Happy New Year! It's that time (as of now!) for the UK, and since the Slashdot backend operates in Greenwich Mean Time, that seems as good a reason as any to welcome 2012 now instead of local midnight for any of the various U.S. time zones. Everyone has a different take on how to rank the events of the last year; read on below for a few notes on some of the goings on of the past 31,536,000 seconds (give or take). The list is pretty arbitrary, drawn from the thousand-ish stories that hit the Slashdot page in that time; please say in the comments what news hit you the hardest this year.
