Sean Burgess (right) and Bruce Draper, professors in the UC Davis College of Biological Sciences, are using zebrafish to detect chemicals that may cause reproductive harm. The GloNad fish glow red or ...

A novel system that chases larval zebrafish around an arena with predator robots is enabling scientists to understand how these days-old fish quickly learn in the real world. A novel system developed ...

The ability of some animals to dynamically change color to match the brightness of their surroundings is one of nature's great survival tools, allowing flatfish to blend into sandy seabeds, frogs to ...

Small prey-like items elicit a quick response from zebrafish larvae, as excitatory brain cells fire. However, large visual stimulus covering the zebrafish's field of vision fires off inhibitory cells, ...

When scientists attempt to transfer genetic material into an organism, they often use an electric field, a technique called "electroporation," that makes cell walls more permeable. This sophisticated ...

Transgenic zebrafish, or zebra danio (Danio rerio), have been bioengineered into a patented and trademarked brand of genetically modified (GM) fluorescent fish and marketed as “GloFish”. (Credit: ...

This shows in vivo-imaging of the blood circulation system in a three-day-old zebrafish larva. The left picture shows a side view of the head, the middle picture a side view of the trunk and the right ...

A novel system developed by Janelia researchers that chases larval zebrafish around an arena with predator robots is enabling ...
