Abiotic chemistry in Earth’s atmosphere could have generated biologically important organosulfur molecules as life was ...

Scientists found 3.3 billion-year-old biosignatures in ancient meteorites and fossils—a billion years older than we thought ...

In a remote desert, scientists have discovered one of Earth’s oldest asteroid impacts. It dates to well over a billion years ago, to a time when our planet was inhabited solely by single-celled life.

Pairing cutting-edge chemistry with artificial intelligence, a multidisciplinary team of scientists today published fresh chemical evidence of Earth’s earliest life – concealed in 3.3-billion-year-old ...

What types of animals first existed on Earth long ago? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists ...

Using a highly sensitive mass spectrometer capable of detecting trace chemicals, the researchers discovered that their early Earth simulation created an entire collection of sulfur biomolecules. These ...
