How Molecular Handedness Emerged In Early Biology
Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions, akin to the left and right versions of human hands. One of the […]
Scripps Research Scientists Reveal How The First Cells Could Have Formed On Earth
Roughly 4 billion years ago, Earth was developing conditions suitable for life. Origin-of-life scientists often wonder if the type of chemistry found on the early Earth was similar to what […]
Where Did The First Sugars Come From?
Two prominent origin-of-life chemists have published a new hypothesis for how the first sugars—which were necessary for life to evolve—arose on the early Earth.
New Role For Cyanide In Early Earth And The Search For Extraterrestrial Life
Today, the colorless and deadly gas cyanide is known as a fast-acting poison and a chemical weapon. Four billion years ago, however, it may have been a harbinger of life. […]
