Some Birds Can See Magnetic Fields 238

Posted by kdawson from the looks-dark-to-the-east dept.
jamie found a post on the Not Exactly Rocket Science blog on research indicating that some birds can literally see magnetic fields, but only if the vision in their right eye is sharp (abstract at Current Biology). "The magnetic sense of birds was first discovered in robins in 1968, and its details have been teased out ever since. Years of careful research have told us that the ability depends on light and particularly on the right eye and the left half of the brain. The details still aren’t quite clear but, for now, the most likely explanation involves a molecule called cryptochrome. Cryptochrome is found in the light-sensitive cells of a bird’s retina and scientists think that it affects just how sensitive those cells are. ... The upshot is that magnetic fields put up a filter of light or dark patches over what a bird normally sees. These patches change as the bird turns and tilts its head, providing it with a visual compass made out of contrasting shades."

Hotels Lead the Industry In Credit Card Theft 135

Posted by kdawson from the shred-everything dept.
katarn writes "A study released this year found that, of the credit card hacking cases last year, 38 percent involved the hotel industry. At hotels with inadequate data security, the greatest amount of credit card information can be obtained using the simplest methods. It doesn't require brilliance on the part of the hacker. Most of the chronic security breaches in the hotel industry are the result of a failure to equip, or to store or transmit this kind of data properly, and that starts with the point-of-sale credit card swiping systems."

AI Predicts Manhole Explosions In New York City 213

Posted by kdawson from the hell's-own-pop-top dept.
reillymj writes "Every so often, a 300-pound manhole cover blows sky high in Gotham, followed sometimes by a column of flame and smoke. (There are a few hundred 'manhole incidents' per year in the city, not all of them this dramatic.) Researchers from Columbia University applied machine learning algorithms to Con Edison's warren of aging electrical wires and sewage access points around Manhattan. As the system learns where dangerous mixtures of sewer gas and decrepit wiring are likely to come in contact, it makes forecasts about trouble spots, including where the next explosion may occur. The team has just completed rankings for manholes in Brooklyn and the Bronx, and plans to return to Manhattan's grid, armed with the most recent inspection and repair data." The research was published in the July issue of Machine Learning.

Good Database Design Books? 291

Posted by timothy from the this-slot-that-tab dept.
OneC0de writes "I am the Director of IT for a small/medium sized marketing company, where I personally write the code that runs our applications. We use a variety of technology at our office, the majority of which rely on MS-SQL and MySQL databases. I am familiar with tables, SQL queries, and have a general understanding of how the SQL databases work. What I'm looking for is a good book, particularly a newer book, to explain general database design techniques, and maybe explain some relational tables. We have some tables that have million of rows, and I'd like to know the best method of designing these tables."

Submission + - Implantable Eye Telescope Finally FDA Approved (singularityhub.com)

Submitted by kkleiner
kkleiner writes: A telescopic implant that fits directly into the eye to treat certain kinds of blindness has finally received FDA approval for use in the US after more than five years of waiting. The Implantable Miniature Telescope (IMT) is used to treat age-related macular degeneration (AMD), a condition that affects millions around the world. For many, the center part of their vision becomes blurred or completely dark. The IMT is surgically implanted into the cornea and acts to expand an incoming image onto the peripheral parts of the retina that are undamaged by AMD. The commercial version of the IMT is called CentraSight and is in development by VisionCare Inc. There are likely hundreds of thousands of potential patients in the US alone who may be able to have their vision partially restored now that CentraSight has garnered FDA approval.

Google Struggles To Give Away $10 Million 145

Posted by samzenpus from the catch-you-tomorrow dept.
theodp writes "On Google's 10th Birthday in 2008, the search giant promised $10 million to the best five ideas for using technology to improve the world, through Project 10^100. CNN reports that while Google's intentions were good, of course, the company's follow-through leaves much to be desired. Google announced the cash prize contest in September 2008 and closed public voting on 16 finalists chosen from over 150,000 ideas in October 2009. Over eight months later, the company has yet to announce the winners. 'While genocide and other pressing problems relentlessly advance,' remarked contest finalist Daniel Meyerowitz to Wired.com, 'it would seem that Project 10^100 does not.'"

Submission + - The Proton Just got smaller (nature.com) 1

Submitted by inflame
inflame writes: A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."'

Would this indicate new physics if proven?

Bill Gates's New Version of the Einstein Letter 407

Posted by Soulskill from the did-he-just-godwin-the-green-revolution dept.
dcblogs writes "In 1939, Albert Einstein sent 'F.D. Roosevelt, President of the United States,' a letter with a warning about Germany's interest in a new type of energy with potential for use as a powerful bomb. The letter also outlined the competitive threat posed by Germany and steps for improving US research efforts. Last week, Bill Gates, along with GE's CEO and others, met with President Obama to deliver their own message: that of the top 30 companies in the world working on alternative energy, only four are in the US. Similar to Einstein's point and recommendations, Gates and his allies are asking the US to view the alternative energy push as a competitive threat posed by other nations, particularly China, which may be doing a better job in bringing its engineering talent and money to bear on this problem."

What Knowledge Gaps Do Self-Taught Programmers Generally Have? 396

Posted by ScuttleMonkey from the mind-the-gap dept.
BeardedChimp writes "I, like many others here, have learned to program by myself. Starting at a young age and learning through fiddling I have taught myself C++, Java, python, PHP, etc., but what I want to know is what I haven't learned that is important when taught in a traditional computer science curriculum. I have a degree in physics, so I'm not averse to math. What books, websites, or resources would you recommend to fill in the gaps?"

Best Buy $39.95 "Optimization" At Best a Waste of Money 504

Posted by ScuttleMonkey from the hooray-for-corporate-scams dept.
DCFC writes "The Consumerist deconstructs the appalling 'optimization service' that Best Buy has been pushing on consumers in recent weeks. The retailer charges 40 bucks to give you a slower PC, and make bizarre claims that it makes it go 200% faster. 'We ran the 3DMark 2003 graphics benchmark on each laptop, comparing optimized and non-optimized settings. For two of our samples, the Gateway and Toshiba, performance changes were negligible. On the Asus laptop, however, optimized tests actually scored about 32% worse than the non-optimized setup. We have been unable to isolate the source of this performance change. On none of the three tested laptops did the optimized settings give a performance boost in our test.'"

Thorium, the Next Nuclear Fuel? 710

Posted by Soulskill from the plenty-on-the-auction-house dept.
mrshermanoaks writes "When the choices for developing nuclear energy were being made, we went with uranium because it had the byproduct of producing plutonium that could be weaponized. But thorium is safer and easier to work with, and may cause a lot fewer headaches. 'It's abundant — the US has at least 175,000 tons of the stuff — and doesn't require costly processing. It is also extraordinarily efficient as a nuclear fuel. As it decays in a reactor core, its byproducts produce more neutrons per collision than conventional fuel. The more neutrons per collision, the more energy generated, the less total fuel consumed, and the less radioactive nastiness left behind. Even better, Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. The design is based on the lab's finding that thorium dissolves in hot liquid fluoride salts. This fission soup is poured into tubes in the core of the reactor, where the nuclear chain reaction — the billiard balls colliding — happens. The system makes the reactor self-regulating: When the soup gets too hot it expands and flows out of the tubes — slowing fission and eliminating the possibility of another Chernobyl. Any actinide can work in this method, but thorium is particularly well suited because it is so efficient at the high temperatures at which fission occurs in the soup.' So why are we not building these reactors?"

Android's Success a Threat To Free Software? 416

Posted by Soulskill from the unintended-consequences dept.
Glyn Moody writes "Two years after its launch, Google's Linux-based Android platform is finally making its presence felt in the world of smartphones. Around 20,000 apps have been written for it. Although well behind the iPhone's tally, that's significantly more than just a few months ago. But there's a problem: few of these Android apps are free software. Instead, we seem to be witnessing the birth of a new hybrid stack — open source underneath, and proprietary on top. If, as many believe, mobile phones will become the main computing platform for most of the world, that could be a big problem for the health of the free software ecosystem. So what, if anything, should the community be doing about it?"

Black Soot May Be Aiding Melting In the Himalayas 336

Posted by kdawson from the not-yeti dept.
Hugh Pickens writes "The Himalayas, home to some 10,000 glaciers, are the main source of replenishment to lakes, streams, and some of the continent's mightiest rivers, on which millions of people depend for their water supplies. Since the 1960s, the acreage covered by Himalayan glaciers has declined by more than 20 percent with a rate of warming twice the global average over the past 30 years. Now Live Science reports that tiny particles of pollution known as 'black carbon' — and not heat-trapping greenhouse gases — may be causing much of the rapid melting of glaciers in the Himalayas. 'Tibet's glaciers are retreating at an alarming rate,' says James Hansen, director of NASA's Goddard Institute for Space Studies in New York City. 'Black soot is probably responsible for as much as half of the glacial melt, and greenhouse gases are responsible for the rest.' The circulation of the atmosphere in the region causes much of the soot-laden air to 'pile up' against the Himalayas. The soot mixes with other dust from nearby deserts, creating a massive brown cloud visible from space that absorbs incoming solar radiation. As this layer heats up in the Himalayan foothills, it rises and enhances the seasonal northward flow of humid monsoon winds, forcing moisture and hot air up the slopes of the mountain range."
