Unlike in some animals, their sense of magnetoreception appears to be independent of blue light.

A combination of imaging techniques allows researchers to observe subcellular processes within organisms.

Researchers unveil the neural basis of alertness in larval zebrafish.   

Researchers develop a new method to highlight specific cells that reside in the lens of a zebrafish.

Zebrafish larvae transplanted with patients’ tumors respond as their human donors do to chemotherapy.

Sensory neurons in the tip of the zebrafish nose respond to molecular signals released from food sources.

Researchers track a fish in a virtual-reality system as it responds to projections of other fish of the same species.

Experiments that place untethered fish, flies, and mice in simulated environments give clues about the animals’ social behavior.

In a first, scientists reanimate the fish using embedded gold nanoparticles that heat up cells by absorbing laser light.

Zebrafish have a remarkable ability to heal their damaged nerve fibers following a spinal injury.

This fluttering clump of colorful cells is a zebrafish embryo, visualized by many stacked images.

Harvesting lab-raised zebrafish based on their size led to differences in the activity of more than 4,000 genes, as well as changes in allele frequencies of those genes, in the fish that remained.

Zebrafish, Danio rerio, develop patterns of colorful stripes on their skin thanks to pigmented cells—dark melanophores, orange-gold xanthophores, and iridescent iridophores. 

Time-lapse imaging shows the immune cells transferring chemical signals during pigment pattern formation in developing zebrafish.

Immune cells called macrophages shuttle cellular messages in the skin.

A new imaging technique helps scientists see the interactions between molecules in this zebrafish embryo.

A common infection might be skewing experimental data on zebrafish.
