An anonymous reader writes "The male test subjects didn't know what they were smelling, they were just given little vials of clear liquid and told to sniff. But when those vials contained a woman's tears (collected while she watched a sad movie), the men rated pictures of women's faces as less sexually attractive, and their saliva contained less testosterone. Is this proof that humans make and respond to pheromones? The researcher behind the study doesn't use that controversial word, but he says his findings do prove that tears contain meaningful chemical messages."

Torrentfreak reports that after calculating download frequency for pirated copies of popular video games, Call of Duty: Black Ops has won the dubious honor of being the most pirated game of 2010. The PC version of the game was torrented roughly 4,270,000 times, and the Xbox 360 version was downloaded an additional 930,000 times. (The most pirated Wii game was Super Mario Galaxy 2, and Dante's Inferno somehow managed to accrue the most downloads of Xbox 360 games.) Fortunately for Activision, the game has still made over $1 billion in sales, and its 20,000,000+ players have racked up over 600,000,000 man-hours of play time since the game's launch in early November.

By splicing cotton with boron, the third hardest material on the planet, scientists created a shirt that was super elastic but also strong enough to deflect bullets. Xiaodong Li, lead researcher on the project, says the same tech may eventually be used to create lightweight, fuel-efficient cars and aircrafts."
