Researchers at the Kavli Institute of Nanoscience at the Delft University of Technology in the Netherlands have developed a technique for quantum data teleportation that uses deterministic methods to offer one hundred percent accuracy. Previous methods only worked reliably one in every 100 million attempts. [more inside]
Scientific American reports: "An isolated population of Arctic foxes that dines only on marine animals seems to be slowly succumbing to mercury poisoning." Though a definitive causal link is difficult to establish, an isolated population of arctic foxes on Russia's Mednyi Island is believed to be collapsing due to mercury contamination as a result of its seafood-heavy diet. Where does all that mercury in the environment come from anyway? Why, it's another biproduct of burning fossil fuels, of course, and predictably, rates of mercury pollution are only expected to increase. In some places in the US, even rainwater is showing high levels of contamination. [more inside]
In 1994, theoretical physicist Miguel Alcubierre proposed a scheme for virtual faster than light travel using a real-world analog to the familiar science fiction trope known as "Warp Drive." The basic premise exploited certain space-time warping effects predicted by General Relativity to fold space-time, theoretically allowing a specially designed space craft to reach distant destinations effectively at FTL speeds without actually having to accelerate to light speed or beyond at all. There was, however, at least one major problem with the proposal: The math suggested it would require as much energy as the mass of the planet Jupiter to power the thing. But according to newer calculations based on a modified version of Alcubierre's original proposal, warp speed travel may now theoretically be within reach (warning: eyeball-gouging Space.com link), requiring drastically less energy than originally thought. Of course, not everyone's convinced there's anything to see here. And even so, prohibitive energy input requirements may not be the only serious challenge facing the development of real-world warp drive technology, so don't go packing your bags for that long overdue vacation to Risa just yet.
Is it really raining oil in Lousiana? A YouTube video captured by someone claiming to be a resident of River Ridge, Lousiana, roughly 45 miles inland from the Gulf of Mexico, purports to show evidence of just that. The EPA and other experts remain unconvinced, citing the seemingly obvious fact that oil does not evaporate. The local press characterizes the claims as "exaggerations and hysterical falsehoods." But at least one previous study has been offered to argue that oil broken down with dispersants can in fact evaporate under the right conditions. [more inside]
Is life possible even in the coldest depths of space? If so, this tough little guy has long been thought to be a good candidate. Now, finally, analysis of the Tardigrades (a.k.a. "water bears") exposed to open space as part of the TARDIS project is finally complete. So what's the verdict? [more inside]
The Cosmic Womb: Recently published findings from researchers with the Imperial College London’s Department of Earth Science and Engineering seem to bolster the case for extra-terrestrial sources for the origins of life on Earth. (A PDF of the published results can be downloaded here, if you want the technical specifics.) [more inside]
A new round of genetic tests has confirmed it: The 'big lizards' of our childhood fantasies were more likely 'big birds.' In fact, they probably even had feathers, and looked more like this than this. Mind blowing, I know, but I guess this demonstrates that, despite what some may think, science really doesn't have a problem admitting that it got something wrong when new evidence comes to light.
Are We All Really Just Disembodied Brains Floating in Empty Space? Recent mathematical results in the field of cosmology related to the Boltzmann's Brain Problem may point toward a peculiarly arbitrary universe in which, as improbable as it sounds, it's more likely than not. [more inside]
So you thought that old cliche about civil servants having only half a brain was just a conservative canard? Well, think again.
The latest on the so-called "Red Rain of Kerala." The authors of this study suggest the mysterious red biological material provides evidence of Panspermia. The BBC offers this updated look at the topic. (Previously discussed here on MeFi.)
