A clownfish peers out of an anemone in a tank at Georgia Aquarium. Anemones usually sting, kill and eat fish, but not clownfish. Georgia Tech researchers found that the microbial colonies in the slime covering clownfish shifted markedly when the nested in an anemone. Could the microbes be putting out chemical messengers that pacify the fish killer? Credit: Georgia Tech / Ben Brumfield

Swapping Bacteria May Help ‘Nemo’ Fish Cohabitate with Fish-Killing Anemones

Catalog of Cosmic Cataclysms Helps Establish Gravitational Wave Astronomy

Atlanta, GA

A new catalog of cataclysmic events supports the development of gravitational wave astronomy.

A special breed of cichlid fish has allowed researchers to match up gene activation with behavior. The up and down-regulation of genes may actually be steering ritual mating behaviors. The research is potentially useful in understanding autism since some genes involved in the fish behavior have human genetic cousins implicated in autism spectrum disorder.

'Demolition Handshakes' Kill Precursor T Cells that Pose Autoimmune Dangers

Atlanta, GA

A mechanism tries to stop our T cells from causing autoimmune disorders, and it's like a tight handshake that kills overly aggressive T cells.
