Their findings add to the growing list of tasks carried out by an important molecule that is involved in the arrangement of everything from nerve cells to reproductive cells in the developing embryo.

Zebrafish can now be used to study COX deficiencies in humans, a discovery that gives scientists an unprecedented window to view the earliest stages of mitochondrial impairments that lead to potentially fatal metabolic disorders, according to researchers at the University of Oregon.

Funded by an NSERC Idea to Innovations grant and an Ontario Early Researcher Award, Prof. Yu Sun’s group, the Advanced Micro and Nanosystems Laboratory at the University of Toronto (U of T) recently developed a microrobotic technology for automated microinjection of zebrafish embryos.

A special type of cell found in the eye has been found to be very important in regenerating the retina in zebrafish and restoring vision even after extensive damage. Now, a UK team of scientists believe they may be able to use these cells – known as Müller glial cells – to regenerate damaged retina in humans, according to a study published this month in the journal Stem Cells.

A small tropical fish, the curiosity of a Geisinger research scientist and some college students have created the perfect storm of sorts in an attempt to find a cure for one of the world’s most devastating neurological diseases.

Zebrafish cost about a dollar at the pet store. They grow from eggs to hunting their own food in three days. Adults can lay up to 500 eggs at once… and you have more in common with them than you think.

A central pacemaker structure in the brain controls diurnal rhythms of behavior and hormone release. However, biological clocks are also encountered in almost every cell type (so-called "peripheral" clocks), in which they regulate daily changes in cell biology, including cell division. Very little is known to date about how the two clock systems interact.
