(CN) — When it comes to survival, timing is everything — even for fish embryos. And according to researchers, these embryos aren’t just waiting around for the perfect moment to hatch. They’re actively ...

A RIKEN researcher and his colleague have identified how genes are expressed in fish embryos when they first start using their own genetic material. If the same mechanisms apply to humans, they could ...

New research has revealed that fish embryos actively control their hatching timing through a neurohormone, Thyrotropin-Releasing Hormone (TRH), which triggers the release of enzymes that dissolve the ...

Leaving the comfort and safety of home to explore the world is a difficult decision. However, in a tiny coral reef fish called a neon goby, dads help their offspring take the plunge by pushing them ...

The annual killifish lives in regions with extreme drought. A research group at the University of Basel now reports in “Science” that the early embryogenesis of killifish diverges from that of other ...

The fish tanks in the corner, Carlson said, house the male and female zebrafish in separate tanks. The top two tanks are for adults, the lower two for spawning. Carlson puts the males and females ...

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 ...

Have you ever looked at a human embryo and thought, “That kind of looks like a fish”? If you haven’t, you might be surprised to learn that, in a way, we all begin our lives like this. The idea that ...

Scientists report a documented case of a coral reef fish directly regulating when its offspring hatch. Male neon gobies hatch their embryos by removing eggs from the nest with their mouth, ...
