This week, researchers working with the Large Underground Xenon (LUX) detector at the Sanford Underground Research Facility in Lead, South Dakota, announced that they see no signs of the lightweight dark matter particles hinted at by other experiments.
A rare yes/no effort promises to prove either that hypothetical particles called axions are the universe's elusive dark matter—or that they can't be.

"Light echoes" reveal two previously unknown flare-ups from our galactic beast
Astronomers using the Hubble Space Telescope have imaged the earliest galaxy yet, dating from just 700 million years after the big bang, and conclude that it was forming stars at a furious rate 100 times that of the modern Milky Way.
Engineering changes could raise technical risks, but improve odds of success
David Keith has helped usher geoengineering into the mainstream. Actually testing a way to cool the planet is his next big challenge.
Two theorists whose work set the stage for finding the Higgs boson won the Nobel Prize in physics this week, while three biologists who explored various aspects of how cells package, transport, and release their internal proteins earned the physiology or medicine prize.
