The last time someone could shut down the Internet was probably in 1969, when it consisted of two computers. But in recent years, concerned with the possibility of a “cyberattack,” Congress has been exploring such an option.
The free backup service offers much more than just backup

Plenty. At its core, Dropbox is a free service that allows you to store up to two gigabytes of data in a folder that resides on the company’s servers—and any other place you need it. The folder syncs to your computer, smartphone and other Web browser-equipped devices. There’s nothing to configure, and it’s surprisingly fast.
The stomach may be the quickest way to a man’s heart, but it’s a roundabout way to anyone’s bloodstream. That’s why Harvard University biomedical engineer David Edwards invented Le Whif breathable vitamins, which get into blood faster than pills do.
Practice only makes perfect if you know what perfect looks like. A successful free throw, for example, requires a precise arc, spin and release point, and until now, only a good coach could really spot what was off about a shot.
Barry Lee was sitting at his desk one day when his boss at British retailer Toolstation stopped by with a new assignment. He had heard about a drag-racing series for vehicles propelled by power tools, and he wanted to win. “You’re the man to do it,” he told Lee, an IT support manager. Three years, countless man-hours and several versions later, Lee finished Bolt Lightning, a disc-cutter-powered dragster with one speed: fast.
Medicine harnesses the might of the immune system to defeat prostate cancer.

Doctors have been trying to enlist the immune system of patients in the battle against cancer since at least 1893, when physician William Coley of New York Cancer Hospital injected bacteria into a patient’s body in the hopes that it would spur the immune system to fight the bacterial infection and cancer cells alike. The tumor disappeared, and the patient lived for another 26 years. But immunotherapy was eclipsed by radiation and chemotherapy, which showed more-immediate and reproducible results.
A century of agricultural innovation vastly increased the amount of food--but with it came an increased population, and now hunger is on the rise. Fixing it will require an unlikely alliance

Among the tree-lined bike paths, automated livestock pens and darkened lecture halls of the University of California at Davis, a tiny room holds a weapon of mass destruction. Here, behind locked doors, sits a chunk of Xanthomonas, a bacterial blight that has decimated rice harvests in China, India, Indonesia, Malaysia, the Philippines, Thailand, Vietnam and West Africa. Since the passage of the Bioterrorism Preparedness and Response Act of 2002, the U.S.
Next-generation blast-ready headgear draws inspiration from Nascar and Star Wars alike

Improvised explosive devices are one of the biggest threats to soldiers in Afghanistan and across the world. They unleash a shock wave that can travel about 1,000 feet per second and hit with a pressure of 100 pounds per square inch. The U.S. Army's standard-issue Kevlar combat helmet absorbs some of that force, but it isn't designed to protect the soldier's face from shock waves, which studies suggest can pass through the eyes, nose and mouth to the brain. Nor does it prevent a soldier's head from jerking around, which can cause brain damage. Fortunately, Army researchers are exploring new designs that could someday protect troops from these hazards.
How does GM encourage adoption of its mild-hybrid system? Make it standard
By Lawrence UlrichPosted 01.20.2011 at 12:15 pm 2 Comments
“Mild” hybrids, with their puny batteries and weak electric motors, have largely failed in the marketplace. Next to “full” or “strong” hybrids such as the Toyota Prius—which has a sizeable battery pack and a powerful electric motor and can run under electric power for short stretches—cars like the now-discontinued Chevrolet Malibu hybrid were more expensive than the conventional model but provided only a negligible boost in fuel economy. With the 2012 Buick LaCrosse, however, GM is launching eAssist, a mild-hybrid system that the company hopes will change that equation.
