"Earth's most eminent emissary to Mars has just proven that those rare Martian visitors that sometimes drop in on Earth — a.k.a. Martian meteorites — really are from the Red Planet. A key new measurement of Mars' atmosphere by NASA's Curiosity rover provides the most definitive evidence yet of the origins of Mars meteorites while at the same time providing a way to rule out Martian origins of other meteorites."

"Millions of years have evolution has resulted in plants being the most efficient harvesters of solar energy on the planet. Much research is underway into ways to artificially mimic photosynthesis in devices like artificial leaves, but researchers at the University of Georgia are working on a different approach that gives new meaning to the term 'power plant.' Their technology harvests energy generated through photosynthesis before the plants can make use of it (abstract), allowing the energy to instead be used to run low-powered electrical devices."

"A Reuters blog post by Yousaf Butt explains the science, or lack thereof, behind recent claims that Iran is closer to building the bomb. Butt has been writing in the Bulletin of the Atomic Scientists, most recently blasting the unsourced AP 'Iranian graph' that claimed to show nuclear testing activity as well as the Washington Post story about Iran's alleged order of 100,000 magnets for their centrifuges."
