At the bottom of an icy Antarctic lake, a thin, slimy layer of bright green microbes is generating a tiny oasis of oxygen that might give a picture of what early Earth looked like before oxygen became common in the atmosphere.

Nearing the Limits of Life on Earth

It took Jackie Goordial over 1000 Petri dishes before she was ready to accept what she was seeing.

At the bottom of a frigid Antarctic lake, a thin layer of green slime is generating a little oasis of oxygen, a team including UC Davis researchers has found.

When a NASA spacecraft sets off to explore Jupiter's icy moon Europa to look for the ingredients of life, radar equipment designed to pierce the ice of Antarctica will be among the passengers.

Many view Antarctica as a frozen wasteland. Turns out there are hidden interconnected lakes underneath its dry valleys that could sustain life and shed light on ancient climate change.

Where Ice sheet, Ocean and Land Converge

Using a specially designed hot-water drill to cleanly bore through a half mile of ice, a National Science Foundation (NSF)-funded team of researchers has become the first ever to reach and sample the "grounding zone," where Antarctic ice, land and sea all converge.

A National Science Foundation (NSF)-funded research team has successfully tested an autonomous underwater vehicle, AUV, that can produce high-resolution, three-dimensional maps of Antarctic sea ice.

Researchers this week published a paper confirming that the waters and sediments of a lake that lies 800 meters (2,600 feet) beneath the surface of the West Antarctic ice sheet support "viable microbial ecosystems."

Taking the Shine Off Glaciers

The first ecological study of an entire glacier has found that microbes drastically reduce surface reflectivity and have a non-negligible impact on the amount of sunlight that is reflected into space.

I am currently in the high arctic sitting (Axel Heiberg Island, Nunavut, Canada) in a tent next to the Stolz Diapir spring site at Whitsunday Bay.
