The Mars 2020 mission involves sending a rover, named Perseverance, to Mars to look for evidence of past life on that planet. Perseverance will collect samples of 3 billion year old rocks that scientists on Earth think might contain signs READ MORE
Experiments on the International Space Station found that lichens, a combination of algae and fungi, survived in space-like, flight, and Mars-like environments.
Researchers studying a sulfuric acid cave in Italy are among the first to describe organisms found living in gypsum, an acidic mineral deposit found on the cave walls.
The Cassini spacecraft revealed the atmosphere of Saturn has large regions that don’t cycle to the poles and that the atmosphere is filled with waves that disrupt circulation.
Microbes on Earth have adapted to survive in some pretty extreme locations. The extreme dryness of deserts, high salinity in salt deposits, cold temperatures of glaciers, and even high pressures of the deep ocean don’t stop some life forms. Another READ MORE
Researchers found a hidden selenium cycle tied to manganese oxide minerals made by common soil fungi.
Scientists used to think cysteine was required to manufacture itself. Turns out, it isn’t. In fact, cysteine slows down the manufacture of itself. Go figure!
Based on new DNA results, the researchers were able to provide better classification of cyanobacteria.
Sort of like a fossilized microbial lasagna, fossils called “stromatolites” are formed when layered communities of different types of bacteria trap sand, dirt, and debris in their structure over time. Stromatolites are found in rocks as old as 3.5 billion years, and containing the planet’s earliest life forms.
Many organisms live by breathing in oxygen and breathing out carbon dioxide, and those that don’t often live by taking in carbon dioxide and releasing oxygen. However, did you know that these aren’t the only ways life can survive? Researchers recently discovered Sulfurimonas marinigri, a species of bacteria that survives by taking in sulfur and manganese instead of oxygen and carbon. This method of survival has long been theorized, but could never be proven until now.
