There might be a type of exoplanet without dry land. They're called "Hycean" worlds, a portmanteau of "hydrogen" and "ocean." They're mostly or entirely covered in oceans and have thick hydrogen atmospheres.
Cornell researchers have discovered a way for ammonia oxidizing archaea (AOA), one of the most abundant types of microorganisms on Earth, to produce nitrous oxide, a potent and long-lasting greenhouse gas.
Researchers at the U.S. Department of Energy (DOE) Joint Genome Institute (JGI), a DOE Office of Science User Facility located at Berkeley Laboratory, have published a study in Science Advances that evaluates the current ...
Most life on Earth relies on the sun's energy for survival, but what about organisms in the deep sea that live beyond the reach of its rays? A new study led by Woods Hole Oceanographic Institution (WHOI), published in The ...
An oxygen sensor protein protects the enzymatic machinery of biological nitrogen fixation from serious damage, and its use in biotechnology could help to reduce the use of synthetic fertilizer in agriculture in the future.
The streams draining the glaciers on our planet's mountaintops harbor a wealth of unique microorganisms, yet little was known about these complex ecosystems until recently. A team of scientists led by EPFL has carried out ...
Which microbes thrive below us in darkness—in gold mines, in aquifers, in deep boreholes in the seafloor—and how do they compare to the microbiomes that envelop the Earth's surfaces, on land and sea?
Microorganisms have long used hydrogen as an energy source. To do this, they rely on hydrogenases that contain metals in their catalytic center. In order to use these biocatalysts for hydrogen conversion, researchers are ...
To boost crops more efficiently in the future, the evolutionary past may hold key insights. The way that plants process nutrients has a rich back story—they rely on enzymes that have been evolving for billions of years. However, ...
One of the biggest scientific mysteries is where life on Earth started.
