New research has shown that fish embryos actively control the timing of their hatching using a neurohormone called Thyrotropin-Releasing Hormone (TRH). This hormone triggers the release of enzymes that break down the egg wall, allowing the embryo to hatch at the right moment. This discovery reveals a previously unknown neural mechanism that regulates this crucial [...]from SciTechDaily https://ift.tt/Odshj3o
