Researchers have discovered two genes that influence risk for early- and late-onset Alzheimer's disease, which could lead to new ways to fight the disease.

Hawaiian bobtail squid owe their luminescence to bacteria they acquire from the environment. Genetic analysis clarifies how this symbiosis works.

With a new refinement, researchers can use the CRISPR method to edit multiple genes at once, rather than just a few at a time.

Gene mutations in people with long QT syndrome may trigger seizures because of their effect on brain neurons—independent of what they do to heart function.

A new high-resolution picture of cells at work inside the liver may help scientists uncover therapeutic targets to treat disease.

Genes that red algae stole from bacteria to better adapt to hot springs could pave the way for designer algae that make fuel or clean up pollution.

Some flies learn faster than others but a new look at their genes may explain the difference.

A huge new epilepsy study reveals genes that may put people at higher risk and genetic links between the condition's severe and less-severe forms.

Cryptic DNA variation becomes available in an emergency to fuel rapid evolutionary change critical to survival, research finds.

Learning about how the toothy gar fish regenerates its fins and the genes that drive regrowth could shed light on whether the same is possible in people.
