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 ...

During the first 72 hours in particular, extracellular vesicles—nanoparticles enclosed in cell membranes—play a significant role in the embryonic development of zebrafish. This is the result of a ...

Egg specific gravity is of relevance for fish recruitment since the ability to float influences egg and larvae development, dispersal and connectivity between fishing grounds. Using zootechnics, ...

Researchers have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a ...

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body, a remarkable structure that organizes essential molecules to guide early ...

During animal development, embryos undergo complex morphological changes over time. Differences in developmental tempo between species are emerging as principal drivers of evolutionary novelty, but ...

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called ...

(MENAFN- EIN Presswire) EINPresswire/ -- A new study shows that fish embryo toxicity tests using the Chinese rare minnow may provide a promising alternative to conventional acute fish toxicity tests.
