Speak up: Louder neurons form more connections

...mple rule took some technical finesse. Hua created zebrafish with a few brain cells that made a protein that prevented them from firing their normal electrical signals. These cells were also engineered to produce a protein that glowed green under the appropriate light. Hua looked for green neurons in her immo...

Temperature regulates circadian clock in zebrafish

...tions of as little as 2 oC (35.6 oF) can reset the zebrafish clock, Lahiri et al. show, and precise shifts in temperature trigger significant changes in the expression of specific clock genes. More explicitly, clock genes per4, cry2a, cry3, and clock1 showed rhythmic expression under temperature cycles when a...

Tadpole soon to help in the fight against cancer and lymphedema

...r in the study of the blood vessel system. But the zebrafish also offers little comfort, as it does not have any lymphatic vessels. In the early 20th century studies suggested that tadpoles do have lymphatic vessels. This urged Peter Carmeliet and his research group to examine whether tadpoles can form a suit...

Even fish don't swim well when they're young!

... have found what it is that prevents larvae of the zebrafish from reaching top speeds: the larvae cannot maintain their body in a horizontal position while coasting. The research team think this is because larvae don't have the help of an adult swimbladder and have only small, ineffective side-fins. This lack ...

How does a zebrafish grow a new tail?

If a zebrafish loses a chunk of its tail fin, it'll grow back within a week. Like lizards, newts, and frogs, a zebrafish can replace surprisingly complex body parts. A tail fin, for example, has many different types of ce...
