Study tests theory that life originated at deep sea vents
WHOI
One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began, roughly 3.8 billion years ago, but there is still intense debate about exactly how life began. One possibility — that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world — has grown in popularity in the last two decades.

New origin seen for Earth's tectonic plates
Nature
Earth's tectonic plates may have taken as long as 1 billion years to form, researchers report today in Nature. The plates — interlocking slabs of crust that float on Earth's viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another, the report says.

Permafrost thawing could accelerate global warming
reportingclimatescience.com
A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends.
