Researchers simulated nearly every molecule in a bacterial cell — and then watched the cell grow and reproduce.

Biology textbooks explain that cells follow a universal rule when processing gene transcripts to make proteins. Non-coding ...

The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of ...

Fluorescent imaging allows scientists to observe the parasite Toxoplasma gondii in far greater detail, revealing how it ...

Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged ...

A recent study suggests that memories aren’t just stored in the brain, raising important questions about cognition.

A growing body of research is challenging the long-held assumption that memory and awareness belong exclusively to the brain. Scientists working across immunology, biophysics, and neuroscience have ...

Scientists have identified a critical breakdown in the cellular machinery that produces proteins in aging brains.

Scientists tested whether microbes can survive the shock of a planetary impact and found some may endure the violent launch into space.

Hardy bacteria could survive the trip from one planet to another, hidden among the debris from an asteroid impact, a new study suggests, providing possible evidence for a theory that the seeds of life ...

Explore a newly surfaced 1951 CIA document on Soviet cancer research, sparking debate and renewed interest in parasites and antiparasitic drugs as possible therapies.
