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 ...

New technique captures real-time diagnostic 3-D images

Research, recently published in the journal Scientific Reports, makes it possible to follow the development of living organisms up to three millimetres long with three-dimensional images.  These organisms, such as the zebrafish ...

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 ...

Blueprint for blood vessel fusion discovered

The fusion of blood vessels during the formation of the vascular system follows a uniform process. In this process, the blood vessels involved go through different phases of a common choreography, in which the splitting and ...

The origins of a genetic switch

Cilia, microscopic whip-like organelles that protrude from the surface of many cell types, are almost ubiquitous. They are present in all eukaryotes—organisms whose cells have a nucleus—and have diversified to perform ...

Robot-fish interact with live fish

Scientists have developed robot-fish that can interact intelligently with live zebrafish according to a study published in Journal of the Royal Society Interface today.

Researchers find our inner reptile hearts

An elaborate system of leads spreads across our hearts. These leads – the heart's electrical system – control our pulse and coordinate contraction of the heart chambers. While the structure of the human heart has been ...
