'Simple' bacteria found to organize in elaborate patterns

Over the past several years, research from University of California San Diego biologist Gürol Süel's laboratory has uncovered a series of remarkable features exhibited by clusters of bacteria that live together in communities ...

Temporal cues help keep human looking human

Researchers believe that genetically modified bacteria can help explain how a developing animal keeps all of its parts and organs in the same general proportions as every other member of its species.

Snail genetic tracks reveal ancient human migration

Some snails in Ireland and the Pyrenees are genetically almost identical, perhaps because they were carried across the Atlantic during an 8000-year-old human migration. The snail genetics tie in with studies of human genetics ...

Through evolution, cavefish have lost sleep

Cave fish sleep significantly less than their surface counterparts, a finding by New York University biologists that reveals the genes involved in sleep patterns and disorders. Their study, which appears in the journal Current ...

The global invasion routes of the red swamp crayfish

Spanish National Research Council (CSIC) researchers have reconstructed the invasion routes followed by the red swamp crayfish during its human-driven expansion based on the analysis of a mitochondrial gene (COI), which was ...

Aging human bodies and aging human oocytes run on different clocks

Reproductive and somatic aging use different molecular mechanisms that show little overlap between the types of genes required to keep oocytes healthy and the genes that generally extend life span, according to Coleen Murphy, ...
