Visualized: 121-megapixel satellite photos show Earth in glorious, psychedelic detail (video)

We're starting to think the Russians have an inside track on high-resolution space photos. When Nokia's 41-megapixel photo of Earth's horizon was just a twinkle in the 808 PureView designers' eyes, the Russian Federal Space Agency had long since finished taking 121-megapixel photos of the whole planet that we're just now seeing in earnest. Unlike NASA photos, which are usually composites of multiple shots, the Elektro-L weather satellite's images display the entire planet in one ridiculously detailed take from 22,369 miles away. Why the trippy colors? Instead of just displaying Earth as-is -- real colors are so passé, dahling -- the satellite layers on near-infrared imagery that paints vegetation in wide swaths of rust-like orange.

You can get a peep of what a day-night cycle looks like for Elektro-L in the video below, and hop over to the sources to get an inkling of just how insanely detailed the images can be. You can also be slightly jealous of the satellite's network connection: at a minimum 2.6Mbps and maximum 16.4Mbps for bandwidth, odds are that it has faster broadband than you do.

Scientists bend gamma rays, could neuter radioactive waste

Bending most light is easy; bending it in gamma ray form, however, has often been deemed impossible given how hard it is for electrons to react to the extreme frequencies. University of Munich scientist Dietrich Habs and his Institut Laue-Langevin teammate Michael Jentschel have proven that assumption wrong: an experiment in blasting a silicon prism has shown that gamma rays will refract just slightly through the right material. If a lens is made out of a large-atom substance like gold to bend the rays further, the researchers envision focused beams of energy that could either detect radioactive material or even make it inert by wiping off neutrons and protons. In theory, it could turn a nuclear power plant's waste harmless. A practical use of the technology is still some distance off -- but that it's even within sight at all just feels like a breakthrough.
