Just as the human body serves as a habitat for bacteria and other microbes, diverse, tiny organisms known as protistshost their own microbiomes.
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 […]
An international team led by the Centro de Astrobiologia (CAB), CSIC-INTA, and the Universidad Autónoma de Madrid, shows a novel platform for scientific exploration of the most remote places in […]
Extremely hyper-saline ponds from an industrial lithium-concentration process in solar salterns in the Atacama Desert were studied to determine the limits of life at very low water activity.
Scientists have discovered a thriving microbial ecosystem beneath 14 metres of ice covering Antarctica’s Lake Enigma, a previously thought-to-be entirely frozen lake.
The majority of large iron formations (IFs) were deposited leading up to Earth’s great oxidation episode (GOE). Following the GOE, IF deposition decreased for almost 500 Myr.
Editor’s note: As we study how Earth life is put together it is helpful to understand alternate ways that chemistry could combine to form living systems. One way is to […]
Nitrous oxide (N2O) is the third most potent greenhouse gas after carbon dioxide and methane. It can also be oxidized by physical processes to form ozone-depleting substances. Atmospheric concentrations of […]
One excellent biosignature for the present detection of microbial life on Earth is motility, leading to its growing interest within the astrobiological community as an observable attribute that, if detected […]
The collection of environmental DNA (eDNA) samples is often laborious, costly, and logistically difficult to accomplish at high frequency in remote locations and over large geographic areas.
