Diet soda makes us fat, and eating veggies won’t do much of anything unless you eat five full servings a day, study says

Given that Americans drink billions of gallons of diet soda every year, it comes as little surprise that one of the most popular articles abuzz on the New York Times Web site is about the potentially waist-thickening effects of diet soda. The article highlights a recent study conducted by researchers at the University of Minnesota who scrutinized the dietary intake of 9,514 volunteers ages 45 to 64 over the course of nine years. The Times honed in on the effects of diet soda: specifically, drinking one can of the stuff each day can increase the risk of developing metabolic disorder, a scary collection of risk factors including increased waist circumference, high blood pressure and low levels of good cholesterol, by 34 percent.
But the same study also came to an even more depressing conclusion: that consuming a healthy diet dominated by fruits and vegetables does nothing to reduce the risk of contracting chronic disease.
Studies show that biofuels exacerbate global warming

Though the existence of global warming is indisputable at this point, the debate over the best plan of attack to solve the problem and reduce our dependency on petroleum fuels is far from settled. The latest example: Two new studies released this week indicate that that biofuels such as ethanol may accelerate rather than alleviate global warming.
Bring a dead electric screwdriver back to life in seconds by adding quick-charging super capacitors.

Its the do-It-yourselfers version of Murphys Law: Every time you need to sink some tough screws, the battery in your cordless screwdriver is dead. So you do the only thing you can: plug the screwdriver into an outlet and endure the several hours it takes to recharge. But why wait all day?

In the international alliance to fight climate change, the United States is considered the sullen loner. But in the seven years since we rejected Kyoto, changes have begun. Not at the federal level, however. It’s the locals who are making it happen.

There's an interesting essay on CNET about the trend of more and more people migrating to Linux, and why they've basically got the wrong idea. The piece is a response to an article on Linux.com, in which the author describes how he "cobbled together a computer" for his Mom out of cast-offs, then switched her over from Windows to Ubuntu Linux.
Hearing a black hole's song may be the key to understanding cosmic events
By Gregory MonePosted 02.08.2008 at 3:11 pm 2 Comments
Syracuse University physicists hope that a new supercomputer will help them pick out the sound of a black hole from the cosmic symphony. The computer will process data gathered by the Laser Interferometer Gravitational-Wave Observatory, or LIGO, which is designed to listen for the ripples in space-time known as gravity waves.
Atlantis launched on time, but not without difficulty

Despite predictions of bad weather, the shuttle Atlantis did launch yesterday—and it was nearly a flawless affair. Some two minutes after yesterday's liftoff, at least three pieces of foam or other debris fell off the shuttle, and now the crew is preparing to inspect the outside of the ship for signs of damage, especially the wings and nose.
The shuttle, which was delayed for two months, will reach the International Space Station tomorrow and deliver the $2 billion Columbus laboratory, a major step towards the eventual completion of the massive rig.
The Internet depends on three-inch-thick cables that stretch from continent to continent
By Lauren AaronsonPosted 02.08.2008 at 1:31 pm 5 Comments
Undersea cables have made big news in the last few days, ever since several cables were cut last week near Dubai and Alexandria, disrupting Internet service all over the Middle East. (The latest news: It looks like a ships anchor sliced one of the cables. Oops!) The accident draws attention to how much our modern lives depend on unseen cables—just three inches thick and buried under sand—that most of us have never even thought about. There are hundreds of thousands of miles of these things snaking under our seas, with even more on the way.
During a week of attempting to cloak every aspect of daily life, our correspondent found that in an information age, leaving no trace is nearly impossible

In 2006, David Holtzman decided to do an experiment. Holtzman, a security consultant and former intelligence analyst, was working on a book about privacy, and he wanted to see how much he could find out about himself from sources available to any tenacious stalker. So he did background checks. He pulled his credit file. He looked at Amazon.com transactions and his credit-card and telephone bills. He got his DNA analyzed and kept a log of all the people he called and e-mailed, along with the Web sites he visited.
