University of Oregon biologists have figured out how zebrafish perfectly regenerate amputated fins with a precisely organized skeleton.
View ArticleResearchers watch blood vessels develop in whole Zebrafish embryos
For the first time, researchers have followed the development of blood vessels in zebrafish embryos without using any labels or contrast agents, which may disturb the biological processes under study.
View ArticleFish also need friends
According to a new study led by Rui Oliveira, researcher at ISPA - Instituto Universitário, Instituto Gulbenkian de Ciência, and Fundação Champalimaud, zebrafish need social support to overcome adverse...

Lynne Sneddon is a myth buster. Having debunked the fisherman's legend that fish don't feel pain, Sneddon, from the University of Liverpool, UK, has become a leading figure in the movement to reduce,...
View ArticleDeadly amphibian plague can infect young zebrafish, scientists discover
The deadly chytrid fungus has for the first time been found to infect and kill species other than amphibians, giving clues on how it causes disease.
View ArticleZebrafish study reveals first fine structure of a complete vertebrate brain
Every thought, every feeling, every sensation—and every behavioral illness—ultimately depends on how our brains work. Despite decades of stunning advances in imaging the brain and measuring its...
View ArticleThis nasal receptor mediates the appetizing smell of fish food
The aquatic environment is full of tantalizing chemicals that can guide a fish to mates or meals. Now, scientists in Japan have identified the olfactory receptor and brain circuitry that picks up the...
View Article3-D models reveal hidden details of zebrafish behavior
Zebrafish have become increasingly popular model animals in preclinical and neurobehavioral research due to their genetic similarity to humans and rapid rate of reproduction. Studies of zebrafish...
