Add drywall to the growing list of toxic imports from China. Today a report from the largest investigation in the history of the US Consumer Product Safety Commission has cited 10 Chinese manufactures as sources of sulfur-laden drywall found in thousands of homes constructed in the United States between 2005 and 2009, when a post-Katrina building boomed created a run on drywall and forced builders to seek out new suppliers.
Today's featured Invention Award winner is SmartSight, a gun-cam system that lets soldiers see around corners and shoot targets without entering the line of fire.
The Rolling Green hills of Sonora, California, no longer lure prospectors with the promise of gold, but for Matthew Hagerty the draw is just as powerful: They're a secluded hideaway ideal for perfecting his military invention, called SmartSight. Ten years in the making, SmartSight is a gun-cam system that allows a soldier to see around corners and shoot targets without putting himself in the line of fire.
It’s midnight. You’re a cop patrolling the wrong side of town when you spot a mugging. The assailant is about 40 feet away, out of range of your stun gun. You shout, but he darts down an alley. It’s a dead end. The crook picks up a bottle, hurls it at your head, and makes a break for the street. You draw your gun.
Thirty-two years after the birth of the world's first test-tube baby, artificial conception has never been more popular or successful. Today, up to 3 percent of infants born in the U.S. owe their existence to assisted reproductive technology, or ART. The majority is overwhelmingly healthy, but new research from scientists at Temple University and other institutions suggests the technique is not without its long-term risks.
When it comes to viruses, especially the serious kind that can make you bleed from your eye sockets and wipe out entire villages, most people naturally prefer to keep their distance. Not Nathan Wolfe. The 39-year-old epidemiologist has spent the past 10 years hunting them down in the jungles of Southeast Asia and sub-Saharan Africa. By collecting thousands of blood samples from wild animals and the people who live in close contact with them, Wolfe and his team have uncovered new viruses related to HIV and smallpox. He's even documented how these animal-borne killers leap to humans, with blood serving as a vector in transmitting viruses from slaughtered animals to hunters.

Can drooling make you a better kisser? Scientific evidence suggests that wet, sloppy smooches pack a bigger biochemical punch than dry kisses and thus may be more likely to lead to sex and reproduction, says Rutgers University researcher Helen Fischer, who spoke today at the AAAS conference in Chicago.
