Researchers found that MDMA reduces anxiety and enhances social behavior in zebrafish by altering key neurochemical systems.

When they exposed zebrafish embryos to this chemical soup, the fish showed significant changes in genes that control fat metabolism and hormone function. Many of these recycled plastics end up in ...

UCSF researchers are scouring millions of compounds – with help from tiny zebrafish – to create anesthetics safe enough to ...

The four zebrafish arrived at the Tiangong space station aboard the Shenzhou 18 spacecraft on April 26, ... as zebrafish embryos are transparent and develop outside of the uterus.

In previous studies of the transparent zebrafish, the researchers discovered a gene called mfsd2aa that, when mutated, caused the BBB to become leaky across the entire brain.

Zebrafish brains share a number of characteristics with those of humans, which is why they’re being used to track the movement of cancer cells in real time.

“The Mruk Lab studies neural injury using the highly regenerative zebrafish larvae,” Mruk says. “Larvae are an ideal model to study migrating cells, as they are both genetically tractable and ...

The study, published this week in the Proceedings of the National Academy of Sciences, applied three-dimensional microscopy to nearly transparent zebrafish to show how weak levels of antibiotics ...

Zebrafish are transparent during their first few weeks of life. Shown here is a larva, or juvenile. Image Credit: Shawn Burgess, NHGRI, Wikimedia Commons.

Gradually, the information from hundreds of zebrafish larvae were combined and used to generate a nerve cell atlas: a "standard brain" with over 2,000 neurons from 72 brain regions. Almost transparent ...

But the boy lived. Born with a rare, complex genetic condition, he owes his life to zebrafish, the nearly transparent creatures that have become the go-to lab animal in countless studies of ...
