Researchers have used zebrafish embryos to propagate the human norovirus, the predominant cause of acute gastroenteritis worldwide.

Of the many qualities that make the zebrafish a model organism, the fact that it shares 70% of the genes humans have makes it an ideal candidate for developmental biology research.

Discovery of new mechanism could have wide implications for other cancers.

The way a gene mutation snuffs out a common social behavior of zebrafish may offer insights into autism in people, researchers report.

Understanding where and how memories are formed could lead to more ways to treat conditions like PTSD and addiction.

Harvard researchers identify a mechanism with therapeutic potential for anemia.

You share the same drug habits, the same age-related memory problems and are similarly impatient when forced to wait for food.

Species can evolve to tolerate higher temperatures – but there's a ceiling beyond which adaptation isn't possible.
