Deep burial in sub-seafloor sediments seems to ‘freeze’ microorganism evolution

Microorganisms can survive in space and on other planets, safe behind dried-up biofilms

Worry and excitement, all in one paper.

How many germs you can find in your home: about 9,000 different species

After they analyzed dust samples collected from 1,200 US households, researchers at University of Colorado at Boulder identified over 9,000 different species of microbes, bacteria and fungus. The exact makeup depends on where the home is located, the gender of the people living inside and whether or not pets are present.

Exotic extreme microbes played a role in Earth’s early atmosphere

Some species of bacteria can survive virtually anywhere: in acids, in nuclear waste, at extremely low or high temperatures, at extreme pressures, and so on; extreme microbes that survive on gases thrown out by Siberian hot springs may have played an extremely important role in the formation of our planet’s atmosphere and its composition, a new study concludes. Extreme exotic
