Zebrafish eggs contain a sunscreen called gadusol that protects the growing embryo from harmful rays. The ultraviolet rays in sunlight are damaging. To shield against this, vertebrates produce a ...

Failure of chromosomal organization within human egg and sperm cells result in miscarriages and infertility. However, the mechanisms controlling these processes are not understood. The discovery of a ...

In the November 21 Proceedings of the National Academy of Sciences, Peterson et al. describe a screen for chemicals that can be used to interfere with, and time, developmental events in zebrafish ...

Molecular developmental biologists used zebrafish embryos to study a gene mutation that causes scoliosis, a sideways curvature of the spine that typically occurs in humans just before puberty. Popular ...

Popular in aquariums all over the world, the zebrafish is native to South Asia. But here in a Cincinnati Children's laboratory, the freshwater variant plays a vital role in scientific discovery. The ...

How a sperm and an egg fuse together has long been a mystery. New research by scientists in Austria provides tantalizing clues, showing fertilization works like a lock and key across the animal ...

Researchers have used the zebrafish (Danio rerio) to identify the role of a gene involved in cardiac rhythm, which could help explain the fundamentals of what it takes to make a human heartbeat.
