Large freshwater aquifers can be found under the porous crust of Earth’s oceans. Though it has been difficult to obtain aquifer samples for study without contaminating the sample or the source with the ocean’s saltwater, it has been predicted that they contain as much as 1/3 of the world’s biomass. A new study into these aquifers has revealed a new species of microbes that Continue reading New Species of Microbes That ‘Breathe’ Sulfate Discovered Under Ocean Crust
Lazymicrobes make possible the soils on which we all depend, a new study suggests. Finding a way to make more of these lazy, or “cheater,” microbesmight help fight global warming.
Earth’s soils hold an estimated 2,500 gigatons of carbon, compared to less than 800 gigatonsin the atmosphere. A 10 percent increase would eliminate global warming, but this is a daunting challenge. These soils have built up over thousands of years;moreover, our understanding of the process is surprisingly Continue reading Cheating Microbes Could Save The Earth
Martian rocks photographed by Curiosity look tantalizingly similar to those created by microbial action on Earth. The observation is far from proof that the rocks have a living origin, but it is nevertheless one of the most promising signs yet found by the Martian missions.
Microbially Induced Sedimentary Structures (MISS) represent some of the oldest evidence for life on Earth, stretching back 3.5 billion years</ Continue reading Were These Mars Rocks Made By Microbes?
As some of you may know, the Antarctic continent isnt just ice all the way through. Although its surface is around 98 percent coveredin frozen water, the remaining 2 percent gives a little hint as to what may lie below. Back in the Cretaceous period, when the non-avian dinosaurs still ruled the world, Antarctica was covered in dense, warm forests, builton a solid bedrock full of valleys, river, canyons, mountains, and lakes< Continue reading Hidden World Discovered Buried Beneath Antarctica
