A new water bear protein can protect the DNA of human cultured cells from otherwise lethal amounts of radiation damage, say a group of Japanese researchers, providing part of the answer to why tardigrades can live in deadly conditions.

A geologist from the University of Aberdeen is taking part in an ocean expedition that aims to discover how far beneath the Earth life can survive.

Cold seeps are places where hydrocarbons, mostly methane, emanate from the sea floor. Unlike the hydrothermal vents, the fluids and bubbles are no hotter than the surrounding seawater, thus the name.

To better understand how microbes behave in extreme environments, one possible proxy, not often considered by astrobiologists, is the human body. Over billions of years of evolution, certain species of microbes inside humans have adapted to environments in the human body that would be extremely rough to many other organisms.

A microbial partnership thriving in an acidic hot spring in Yellowstone National Park has surrendered some of its lifestyle secrets to researchers at the Department of Energy's Oak Ridge National Laboratory.

Hitching a ride in the Soyuz capsule with Tim Peake, Yuri Malenchenko and Tim Kopra were 46 species of small organisms and more than 150 organic compounds. Their voyage was even more intense than the astronaut trio's - these samples spent 18 months in space, bolted to the outside of the International Space Station.

The Danakil Depression in Ethiopia is one of the most inhospitable places on Earth.

The introduction and concentration of electron donors and acceptors in the subsurface biosphere is controlled by the mixing of subsurface fluids, but the mechanisms and rates at which microbial communities respond to changes induced by fluid mixing and transport are relatively unknown.

New Microbes That Thrive Deep in the Earth

They live several kilometers under the surface of the earth, need no light or oxygen and can only be seen in a microscope.

ESA's Expose facility was retrieved today from outside the International Space Station by cosmonauts Yuri Malenchenko and Sergei Volkov, who were completing a spacewalk to place new experiments on the outpost's hull.
