A new study finds mixtures of nucleotide types, rather than pure systems, are more likely to yield the building blocks of life.

Our brains have evolved to the point where we can build artificial brains that might help us understand our brains. Let that sink in.

The discovery that the adenosine derivative aids self-replication adds weight to the theory that life on Earth originated from a mixture of RNA molecules.

Microbes were living on land as early as 3.22 billion years ago, fossilized rocks show, 500 million years earlier than previously documented.

Contrary to some hypotheses, the organelles did not descend from any known lineage of Alphaproteobacteria, researchers find.

Growing evidence points to a once-habitable world—and recent findings suggest that life could exist on Mars today.

Reactions that generate fundamental components of the cell run smoothly in microdroplets, study shows.
