First time accepted submitter Stinky Cheese Man writes "An Antarctic climate research expedition, led by climate researcher Chris Turney of the University of New South Wales, has become trapped in heavy ice near the coast of Antarctica. The captain has issued a distress call and three nearby icebreaker ships are on their way to the rescue. According to Turney's web site, the purpose of the expedition is 'to discover and communicate the environmental changes taking place in the south.'"

cold fjord writes with an excerpt from The Atlantic's profile of Dr. Pat McGovern, a biomolecular archaeologist at the University of Pennsylvania Museum of Archaeology and Anthropology, who has what sounds like a fascinating job: decoding ancient clues about what (and how) humans in the distant past were brewing and drinking. "'We always start with infrared spectrometry,' he says. 'That gives us an idea of what organic materials are preserved.' From there, it's on to tandem liquid chromatography–mass spectrometry, sometimes coupled with ion cyclotron resonance, and solid-phase micro-extraction gas chromatography–mass spectrometry. The end result? A beer recipe. Starting with a few porous clay shards or tiny bits of resin-like residue from a bronze cup, McGovern is able to determine what some ancient Norseman or Etruscan or Shang dynast was drinking." The article points out that McGovern has collaborated with the Dogfish Head brewery to reproduce in modern form six of these ancient recipes.

Taco Cowboy writes "Perhaps it's not much, but China has released a panoramic view of the moonscape where their lander has landed. They 'stitched' up some 60 photos taken by 3 cameras on the Chang'e 3 lander, taken from 3 different angles — Vertical, 15 degrees up, and 15 degrees down. From the picture, there is a significant sized crater is seen, several meters wide, off to the left of Yutu, the (jade rabbit) moon rover, and located only about 10 meters away from the Chang'e-3 lander."

sciencehabit writes "Earth's orbital variations—the wobbling and nodding of the planet on its rotational axis and the rhythmic elongation of the shape of its orbit—can affect the shape of the sea floor, according to new research. Scientists already knew that orbital variations, which are driven by gravitational interactions among solar system bodies, pace the comings and goings of the ice ages by shifting where sunlight falls on Earth. Now, researchers have shown in a computer model that those pressure variations should vary the amount of mantle rock that melts kilometers beneath midocean ridges. That, in turn, would vary the amount of ocean crust that solidifies from the melted rock, changing the thickness of new crust by as much as a kilometer as it slides down either side of a midocean ridge. And the group found that indeed, on the Juan de Fuca Ridge offshore of the Pacific Northwest, the ocean floor is grooved like a vinyl LP record in time with Earth's orbital variations of the past million years."
