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.

universegeek writes "Mathematician Ken Ono, from Emory, has solved a 250-year-old problem: how to exactly and explicitly generate partition numbers. Ono and colleagues were able to finally do this by realizing that the pattern of partition numbers is fractal (PDF). This pattern allowed them to find a finite, algebraic formula, which is like striking oil in mathematics."

Researchers from Rice University have found a type of amoeba that practices a sort of "primitive farming behavior." When their bacteria food become scarce, the Dictyostelium discoideum will group together and form a "fruiting body" that will disperse bacteria spores to a new area. From the article: "The behavior falls short of the kind of 'farming' that more advanced animals do; ants, for example, nurture a single fungus species that no longer exists in the wild. But the idea that an amoeba that spends much of its life as a single-celled organism could hold short of consuming a food supply before decamping is an astonishing one. More than just a snack for the journey of dispersal, the idea is that the bacteria that travel with the spores can 'seed' a new bacterial colony, and thus a food source in case the new locale should be lacking in bacteria." It's good to know that even a single celled creature is not immune to the pull of Farmville.

coondoggie writes "NASA today showed off the amazing first pictures of the Sun taken from its 6,800lb Solar Dynamics Observatory flying at an orbit 22,300 miles above Earth. The first images show a variety of activity NASA says provide never-before-seen detail of material streaming outward and away from sunspots. Others show extreme close-ups of activity on the sun's surface. The spacecraft also has made the first high-resolution measurements of solar flares in a broad range of extreme ultraviolet wavelengths."

Develop reports that Crytek, makers of the Far Cry series, the Crysis series, and the game engines behind them, have plans to release a free-to-use version of CryENGINE 3, the software's latest iteration. Quoting: "Unreal vendor Epic Games and Unity have both seen their user-bases mushroom overnight since launching versions of their own engines that, while tied to different royalty rates, are completely free to download and operate. Now the CryEngine 3 group has revealed it wants to tap into this thriving market. The firm's CEO Cevat Yerli told Develop that Crytek already gives away a CryEngine 2 editor to the mod community, but explained that Crytek's expansion strategy stretches beyond. 'We have a very vivid community of users and modders and content creators, and usually that's a great way of unlocking the engine,' he said. ... 'So far that's what we've been offering for free, and it's easy entry into the production environment. [But] we do want to make a standalone free platform that people can run independent of CryEngine that will also be up to speed with the latest engine.'"

@VentureBeat writes "Youtube pulled the original 'Rickroll' video Wednesday night. Don't worry, after a lot of email about the loss of such an important piece of cultural history, Youtube put it back up, saying that they're never gonna say goodbye to the video that's had over 30 million views."

cremeglace writes "Scientists are dismayed and outraged at a new project by the UK border agency to test DNA, hair, and nails to determine the nationality of asylum seekers and help decide if they can enter the UK. 'Horrifying,' 'naive,' and 'flawed' are among the words geneticists and isotope specialists have used to describe the 'Human Provenance pilot project.' The methods being used to determine ancestry include fingerprinting of mitochondrial DNA and isotope analysis of hair and nails. ScienceInsider blog notes that it is 'not clear who is conducting the DNA and isotope analyses for the Border Agency,' and that the agency has not 'cited any scientific papers that validate its DNA and isotope methods.' There is also a followup post with more information on the tests that are being used, and some reactions from experts in genetic forensic analysis. This story was first reported in The Observer on Sunday."

Shane O'Neill writes "Ronald McDonald and the NBC Peacock may get more TV air time, but today's operating systems have cool logos, too. Google, Apple, Microsoft and the Linux crowd crafted mascots ranging from cute lizards to circles of life. In this slideshow, we look at the origins of the logos and look ahead to their future."
