Explore the incredible science of parthenogenesis, a natural reproductive process where some animals can produce offspring without males. From reptiles to insects, discover how nature adapts in surpri ...

Around 200 million animals are used in lab research around the world each year. Organoids may one day replace them.

The family of Henrietta Lacks has settled another lawsuit over the use of her cells, which were taken without consent during treatment at Baltimore’s Johns Hopkins Hospital in 1951.

The tiny Amazon molly (Poecilia formosa) has always fascinated researchers because, according to the rules of evolution, it shouldn't have survived as a species, let alone thrive as a species for over ...

Microglia (immune cells) and the RANK protein are essential for triggering puberty and maintaining fertility in the brain.

Amazon mollies don't need a man, and never will. A new study finds they can purge and repair genetic mutations that would otherwise plague a self-cloning species.

To model bacterial life, Thornburg and his colleagues turned to one of its simplest examples: a bacterial cell with a ...

When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

Until now, conventional 3D cell cultures have often been either too rigid or too unstable to realistically reproduce the ...

Herpes simplex virus partially liquifies the tightly packed, gel-like interior of human cell nuclei to copy itself faster, a new study shows.

Our immune system relies on T cells to fight infections. But T cells don't just show up and react—first, they train, get a game plan, and coordinate their defenses in lymphoid organs. Researchers have ...
