New research suggests that in addition to being one of history's cruelest conquerors, Genghis Khan may have been the greenest. It is estimated that the Mongol leader's invasions unintentionally scrubbed almost 700 million tons of carbon from the atmosphere. From the article: "Over the course of the century and a half run of the Mongol Empire, about 22 percent of the world's total land area had been conquered and an estimated 40 million people were slaughtered by the horse-driven, bow-wielding hordes. Depopulation over such a large swathe of land meant that countless numbers of cultivated fields eventually returned to forests. In other words, one effect of Genghis Khan's unrelenting invasion was widespread reforestation, and the re-growth of those forests meant that more carbon could be absorbed from the atmosphere." I guess everyone has their good points.

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."

University of Idaho scientists have figured out a more effective way to track woodpecker populations than following the incessant laughter. They're using a laser onboard NASA's Icesat spacecraft to determine where the birds might be living. From the article: "NASA's Icesat satellite was initially intended for measuring glacial surfaces at the Earth's poles but has proven to be quite effective in measuring vegetation also. The satellite's laser bounces off of forest canopies, tree trunks and the ground making important characteristics about the forest easily measurable. For example, forest density is determined by the relative amount of light returned versus that which is returned from the ground. Once ideal woodpecker locations are identified 'we actually conduct ground-based woodpecker surveys in these locations as well to verify it,' says team-member Patrick Adam."

Ponca City writes "The Telegraph reports that an online dating profile created by Julian Assange in 2006 has been unearthed from OKCupid disclosing that the WikiLeaks editor sought 'spirited, erotic' women 'from countries that have sustained political turmoil.' Writing under the pseudonym of British science fiction author Harry Harrison, Assange described himself as a 'passionate, and often pig headed activist intellectual.' Assange said he was seeking a 'siren for [a] love affair, children and occasional criminal conspiracy' adding that he was 'directing a consuming, dangerous human rights project which is, as you might expect, male dominated' and added enigmatically: 'I am DANGER, ACHTUNG.' Among Assange's listed interests were the 'structure of reality' and 'chopping up human brains' – although he added the caveat '(neuroscience background)' lest the latter put off potential admirers. 'I like women from countries that have sustained political turmoil,' Assange wrote. 'Western culture seems to forge women that are valueless and inane. OK. Not only women!'"

IamTheRealMike writes "The US State Department has started to warn potential recruits from universities not to read leaked cables, lest it jeopardize their chances of getting a job. They're also showing warnings to troops who access news websites and the Library of Congress and Department of Education have blocked WikiLeaks on their own networks. Quite what happens when these employees go home is an open question." Update: 12/04 17:48 GMT by T : The friendly warning to students specifically cautioned them not to comment online or otherwise indicate that they'd read any of the leaked information; reading them quietly wasn't specifically named as a deal-breaker.

Kozar_The_Malignant writes "The secretive X-37B robotic space plane has returned to Earth after a seven-month mission. This was the vehicle's first flight. Looking like a cross between a Predator Drone and the Space Shuttle, it landed at Vandenberg AFB in California, which was to have been the military's shuttle launch facility. Speculation is that the X-37B is an orbital spy platform."
