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 ...

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

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 ...

Timelapse of a gene-edited medaka fish embryo undergoing mitosis. The mitotic spindle – the green strands in the middle of the cells – can be seen aligning and segregating duplicated chromosomes, ...

A cross-department collaboration headed by researchers at Harvard Medical School and Harvard University has witnessed the moment at which cells in the zebrafish embryo heart start beating in unison ...

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.
