The evolution of Dark-fly

On November 11, 1954, Syuiti Mori turned out the lights on a small group of fruit flies. More than sixty years later, the descendents of those flies have adapted to life without light. These flies—a variety now known as ...

Sex chromosomes have reverted to autosomes multiple times in flies

At the GSA Drosophila Research Conference, scientists will present evidence of many reversals of sex chromosome to autosomes in flies. They identified nine independently evolved sex chromosomes in a wider variety of fly species ...

Molecule induces lifesaving sleep in worms

Sometimes, a nematode worm just needs to take a nap. In fact, its life may depend on it. New research has identified a protein that promotes a sleep-like state in the nematode Caenorhabditis elegans. Without the snooze-inducing ...

First gene linked to temperature sex switch

The sex of many reptile species is set by temperature. New research reported in the journal GENETICS identifies the first gene associated with temperature-dependent sex determination in any reptile. Variation at this gene ...

Wine yeast genomes lack diversity

Sequencing the genomes of hundreds of strains of the wine yeast S. cerevisiae has revealed little genetic diversity and high levels of inbreeding. In many cases, yeast strains sold by different companies were almost genetically ...
