Scientists solve mystery of Death Valley's 'sailing' stonesDeath Valley's Racetrack Playa is the scene of an enduring scientific mystery: Rocks of all sizes seem to move uphill on their own, leaving tracks in the mud behind them. Now, scientists finally have an answer.
Will global warming produce more intense snowstorms?A glimmer of good news for those who don't like shoveling: The intensity of snowstorms is not likely to increase as the planet warms, although fierce snowstorms will become more frequent this century, say scientists.
Astronomers stitch together best view yet of distant galactic mergerUsing data from space- and ground-based telescopes, a team of astronomers have obtained the sharpest view yet of two ancient galaxies colliding.
Will climate change wipe out the sequoias?California's iconic sequoias might face new challenges as the state becomes warmer and drier over the next century, say researchers.
Curiosity passes on drilling Mars rock, keeps on rovingNASA's Curiosity Mars rover has deemed a potential drilling target too unstable, instead opting to resume its journey to Mount Sharp.
Paleontologists discover world's oldest known musclesA marine creature living some 560 million years ago had features that scientists believe are the earliest known examples of muscle tissue.
Duxbury Beach: Shark spotted in Massachusetts watersDuxbury Beach: Swimmers were ordered out of the water after a large shark was spotted near the shoreline.
Tiny bubbles: bonanza for study of climate change's impact on marine methaneThe continental margins off the US East Coast are sending bubbles of methane into the water. These naturally occurring seeps could provide a critical baseline to gauge the effect of climate change on these emissions.
Is that really a thigh bone on Mars? NASA gives predictable answer.What looks like a partly buried thigh bone on the surface of Mars is really just a rock formation, says NASA.
NASA could use 'swarmies' to explore other worldsThe next generation of space explorers could be a swarm of small, relatively simple autonomous robots that cooperate with each other.
- Hypersonic space weapon self-destructs seconds after liftoff
The US Army tested its Advanced Hypersonic Weapon on Monday at the Kodiak Launch Complex in Alaska, destroying the vehicle seconds after liftoff after a technical glitch prompted the test to be scrubbed.
Iceland's Bardarbunga volcano has been shaking for more than a week. Will it erupt?Bardarbunga has been rumbling lately, prompting at least one apparently false report of a subglacial eruption and a brief ban on flights over the Icelandic volcano.

Archaeologists awl worked up over ancient piercing toolA copper awl unearthed in Tel Tsaf, an archaeological site in Israel, indicates the presence of a vast metal trade hundreds of years earlier than previously thought.
Scientist creates most detailed map ever of Neptune's largest moonUsing images snapped by a NASA spacecraft 25 years ago, a scientist has created the most detailed-ever map of Triton, one of the few geologically active moons in our solar system.
- Scientists spot hundreds of methane plumes along US East Coast
A survey of the Atlantic Coast has detected hundreds of gas plumes – almost certainly methane – seeping up from the ocean floor.
At ease, Iceland: volcano alert deemed false alarmIceland relaxed a volcano alert spurred by reports of subglacial activity. The alert, which had shutdown much Europe's airspace for six days, proved to be unfounded.
Iceland volcano: Code Red warning issued for aviationA subglacial eruption is underway at the Bardarbunga volcano in Iceland. Seismic data indicates that lava from the volcano is melting ice beneath the Vatnajokull glacier. An eruption that could cause "significant emission of ash into the atmosphere."
