Bacteria Needed to Make Fertile Soil
A new study shows that dead bacteria are important in soils because their biomass is converted to organic soil components.
Microbes that Fight Greenhouse Gases
Nitrous oxide is released into the atmosphere could cause more damage to Earth's environment than carbon dioxide. Luckily, a previously unknown army of microorganisms helps transform the nitrous oxide into harmless nitrogen gas.
Methane and Marine Microbes
Scientists have discovered a single Archaea that can perform marine methane oxidation coupled to sulfate respiration. Previously, it was thought that Archaea carried out this process in colaboration with a bacterium.
A Mass Extinction's Lessons for the Modern World
A new study suggests that the structure of ecosystems in North America increased the severity of the mass extinction that wiped out the dinosaurs.
Evidence for Ancient Life Throughout the Land
New research suggests that Earth's early microbes may have been widespread on land, despite the fact that the ozone layer had not yet formed.
Bacteria are Social Creatures
New research has revealed that bacteria can have social structures similar to plants and animals. The study provides new insight into mechanisms that could effect the evolution of life on Earth.
Weird Microbe Chemistry Releases Methane from the Ocean
Scientists have discovered "weird chemistry" practiced by the most abundant microbes on the planet, and could be responsible for up to 4 percent of the methane on Earth.
The Constructal Law
Why do bigger creatures tend to have longer lifespans? A new theory suggests that this biological mystery could be explained by a physical law called the Constructal Law.
The Rare Biosphere of the Human Body
The landmark publication of a "map" of the bacterial make-up of healthy humans has deep roots in an unexpected place: the ocean.
A 10-Million-Year Recovery from Mass Extinction
New research indicates that it took 10 million years for Earth to recover after the largest mass extinction known.
