Current climate models have so far been unable to adequately reproduce the clouds over the Southern Ocean around Antarctica. An international team has now taken an important step towards filling […]
Many of the recently discovered Earth-like exoplanets are hosted by M and F stars, stars that emit intense UVC, especially during a flare.
Extreme environments impose strong mutation and selection pressures that drive distinctive, yet understudied, genomic adaptations in extremophiles.
We propose a hypothesis for the simultaneous emergence of bacteria, archaea, viruses, and mobile elements by sequential and concrete biochemical pathways.
Venus is not generally at the forefront when considering extraterrestrial life. Yet, based on the physical similarities and proximity to Earth and with the little knowledge of its evolutionary history, […]
An international team of scientists have unlocked a key piece of Earth’s evolutionary puzzle by decoding the structure of a light-harvesting “nanodevice” in one of the planet’s most ancient lineages […]
We report on the formation of membranous protocells by self-assembly of lipids on micrometeorites, the extraterrestrial particles that have been continuously reaching the surface of the Earth ever since its […]
Some astrobiological models suggest that molecular clouds may serve as habitats for extraterrestrial life.
Life emerged on Earth some 3.8 billion years ago. The “primordial soup theory” proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously […]
A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo has uncovered a surprising role for calcium in shaping life’s earliest molecular structures. […]
