When a fish becomes fluid

Zebrafish aren't just surrounded by liquid, but turn liquid—in part—during their development. As the zebrafish embryo develops from a ball of cells to a fully-formed fish, a region of the embryo switches its phase from ...

The role of tiny RNA in genetic diversity

All species, from zebrafish to humans, possess a genetically diverse collection of traits that allow them to adapt to changing environments. Yet scientists do not fully understand how organisms reach a state of optimal diversity—just ...

Histones and the mystery of cell proliferation

Before cells divide, they create so much genetic material that it must be wound onto spools before the two new cells can split apart. These spools are actually proteins called histones, and they must multiply at the same ...

New research tool targets microRNA expression in zebrafish

A new research tool for studying microRNA expression in zebrafish will help researchers study the effects of miRNA on the early development of this model organism and better understand developmental and disease mechanisms ...

Fish out of water: Gene clue to evolutionary step

Two genes controlling a tissue protein may have played a role in the key period when fish shed their fins and became limbed land-lovers, a study published by Nature on Thursday said.

Patchwork-like image of developing zebrafish sensory organ

This image may bring to mind a patchwork quilt, or a picture taken from a gallery of abstract paintings, but the artisan behind it is actually Mother Nature, with a little help from scientists at the European Molecular Biology ...
