A key player in the maturation of sexual organs

Puberty is a period of extensive changes of body morphology and function. Relatively little is known about what sets the whole process in motion. Thanks to studies in the tiny worm C. elegans, the group of Helge Großhans ...

New CRISPR-powered device detects genetic mutations in minutes

A team of engineers at the University of California, Berkeley and the Keck Graduate Institute (KGI) of The Claremont Colleges combined CRISPR with electronic transistors made from graphene to create a new hand-held device ...

Engineering cellular function without living cells

Genes in living cells are activated – or not – by proteins called transcription factors. The mechanisms by which these proteins activate certain genes and deactivate others play a fundamental role in many biological processes. ...

Male fish can thank genes for colourful looks

Striking traits seen only in males of some species – such as colourful peacock feathers or butterfly wings – are partly explained by gene behaviour, research suggests.

Two-step path to shrinking worker bee gonads

The dramatic difference in gonad size between honey bee queens and their female workers in response to their distinct diets requires the switching on of a specific genetic program, according to a new study publishing March ...
