Proteins are life's molecular workhorses, doing everything from turning sunlight into food to fighting viruses. They are ...

Amino acids, which are a key ingredient of life, could have originally been made in interstellar molecular clouds like that from which the solar system formed, before winding up in asteroids that ...

Scientists are making a case for adjusting our understanding of how exactly genes first emerged. For a while, there’s been a consensus about the order in which the building-block amino acids ...

Many amino acids have been detected in meteorites, while the Rosetta mission detected the amino acid glycine in comet 67P/Churyumov–Gerasimenko; amino acids were also found in the sample of ...

Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, reports a research team. This type of ...

By simulating early Earth conditions in the lab, researchers have found that without specific amino acids, ancient proteins would not have known how to evolve into everything alive on the planet ...
