A new way to look for signs of ancient life on Earth and Mars Scientists have found that high concentrations of rare elements might be evidence of life near ancient hot springs.

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

What can sulfur-eating microbes teach us about life in extreme environments? Microbes living in an extreme environment hosted by a rock called serpentinite use a variety of sulfur compounds to gain energy and survive, which has implications for life that might exist elsewhere in our Universe.

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

More than decomposers: fungi influence the recovery of pollutants in the environment Researchers found a hidden selenium cycle tied to manganese oxide minerals made by common soil fungi.

Have you ever driven past an old factory building and wondered what ever happened to the harsh chemicals that were used there? If you guessed that a lot of the chemicals ended up in the environment, you would be right. READ MORE

A Special Kind of Bacteria Lets Cement Fix Itself Mineral-forming bacteria that grow best in fast-flowing liquid may be the glue that researchers need to close cracks in underground cement.

Samantha Peterson

Cement is one of those common building materials that you can find just about anywhere. When the cement starts to get cracked, fixing it is generally an easy task that involves widening the crack slightly before filling it with more READ MORE

Oxygen, nitrogen, and what happens when biology gets involved How the Great Oxidation Event and photosynthesis created the nitrogen cycle we know today

Sciworthy Staff

When studying Earth’s past, researchers want to understand how nutrients like nitrogen cycled and the impact biology had on them. Scientists rely on ancient rock, soil, fossils, and marine sediment to understand the world that used to be.  Approximately 2.5 READ MORE
