Among these cave insects, the females evolved to have penises — twice. The reasons challenge common assumptions about sex.

Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals.

Emerging evidence suggests that the brain encodes abstract knowledge in the same way that it represents positions in space, which hints at a more universal theory of cognition.

As it becomes clear that the body’s cells have more diverse regenerative capabilities than expected, experts have had to reconsider their approach to stem cell research.

Some researchers are using a complexity framework thought to be purely theoretical to understand evolutionary dynamics in biological and computational systems.

Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.

As chemists tie the most complicated molecular knot yet, biophysicists create a “periodic table” that describes what kinds of knots are possible.

Renee Reijo Pera has spent decades uncovering how the timing of embryonic development contributes to health and disease.

By measuring mechanical forces inside an embryo for the first time, researchers have shown how a physical “jamming” mechanism assists development.
