One theory follows that along the shores of the Black Sea about 9,500 years ago, a huge flood suddenly drowned the landscape, forcing some of the planet's first farmers to move elsewhere. A new study paints a different picture. (Discovery News) more...
Earth's surface is riddled with fractures, whether they be devastating faults, dank caves or mud cracks on a drying desert plain, and now a new study has found that the cracks exhale large quantities of gas—perhaps enough to affect global warming. (Discovery News) more...
With the help of some new tools, a few groups of scientists are getting a more in-depth (literally, in some cases) view of earthquake faults and the motions they produce. (Live Science) more...
Erosion of a stretch of Alaska's coast surged in recent years to more than double the average historical rate. (Live Science) more...
According to a new theory about how mass die-offs work, cosmic collisions generally aren't enough to cause a major extinction event. To be truly devastating, they must be accompanied by another event that inflicts long-term suffering, like runaway climate change due to massive volcanic eruptions. (Discovery/MSNBC) more...
A marine census released Monday documented 7,500 species in the Antarctic and 5,500 in the Arctic, including several hundred that researchers believe could be new to science. (ABC News) more...

Oceanographer Eddie Bernard said progress has been made in understanding tsunamis but the science of predicting earthquakes, the disturbance that causes 90 percent of tsunamis, is still unreliable. (Earth & Sky Radio) more...
In one of the most extreme climate change scenarios, a blistering drought will dry up the Amazon forest, which will ignite and burn away, leaving the world's rain patterns disrupted. (New Scientist) more...
