Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...

(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 ...

RIKEN researchers have determined the molecular structure of an enzyme that occurs in fish. This could shed light on molecular processes in a wide range of marine organisms. The work is published in ...

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 ...

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 ...

Fish embryos inhabit a critical life stage in which subtle shifts in temperature, oxygen availability, salinity and chemical milieu can exert profound effects on survival, growth trajectories and ...

Naturally occurring haploids are predominantly documented in plants; the first report dates to 1923, when haploid individuals were identified in the Jimson Weed. Haploidy also occurs in certain animal ...

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 ...

Plastic pollution in freshwater is increasing, leading to micro- and nanoplastic buildup. A study found these particles and their surface charge can harm fish reproduction, especially under stress.

Plastic contamination in freshwater ecosystems continues to rise, resulting in micro- and nanoparticle accumulation in the aquatic environment. A new study by an aquatic ecology group at the ...
