Sex, lice and videotape

A few years ago, Scott Villa of Emory University had a problem. Then a graduate student at the University of Utah, he was stumped with an issue never addressed in school: How does one film lice having sex?

How important is geographical isolation in speciation?

A genetic study of island lizards shows that even those that have been geographically isolated for many millions of years have not evolved into separate species as predicted by conventional evolutionary theory. Professor ...

Yeast models of cell death and survival mechanisms

European scientists investigated differences in the genomes of various distantly-related yeast and their effects on cell survival. Results may provide insight into cell death induced by free radicals.

Fish go mad for ginger gene

There may be plenty of fish in the sea but the medaka knows what it likes. A new study published in the open access journal BMC Biology shows how a single gene mutation that turns Japanese Killifish a drab grey colour renders ...
