A glucose-powered biofuel cell that uses electrodes made from cotton fiber could someday help power implantable medical devices.

When Boy Fish Build Castles to Impress Girl Fish, Boy Genes Get a Rise

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.

Instinctive behavior may be directly driven be gene regulation, at least researchers were able to match the two up.

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

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

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
Dec 10, 2018 - Atlanta, GA
Why the fish-killing anemone spares the clownfish is a scientific mystery that Georgia Tech marine microbiologists are now tackling in fish mucus.

Powerful X-ray Beams Unlock Secrets of Nanoscale Crystal Formation
