Scientists at Yale and in Singapore have devised what may be the ultimate acid test — a comprehensive model for estimating the origins of Earth’s habitability, based in part on […]
Just as the human body serves as a habitat for bacteria and other microbes, diverse, tiny organisms known as protistshost their own microbiomes.
Beryllium-10, a rare radioactive isotope produced by cosmic rays in the atmosphere, provides valuable insights into the Earth’s geological history.
One leading theory on the origins of life on Earth proposes that simple chemical molecules gradually became more complex, ultimately forming protocells—primitive, non-living structures that were precursors of modern cells.
Searching for life in alien oceans may be more difficult than scientists previously thought, even when we can sample these extraterrestrial waters directly.
Titan’s abundant atmospheric N2 and CH4 gases are notable characteristics of the moon that may help constrain its origins and evolution. Previous work suggests that atmospheric CH4 is lost on […]
By studying prehistoric rocks and fossils emerging from the side of Mount Ashibetsu in Japan, researchers have precisely refined the timing and duration of Ocean Anoxic Event 1a (OAE 1a), […]
Rising sea levels, melting glaciers, heatwaves at sea – 2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees above the preindustrial […]
Saturn’s largest moon Titan is the only place other than Earth known to have an atmosphere and liquids in the form of rivers, lakes and seas on its surface. Because […]
We explore ocean circulation on a rotating icy moon driven by temperature gradients imposed at its upper surface due to the suppression of the freezing point of water with pressure, […]
