‘Sleep gene’ offers clues about why we need our zzzs

By Eric Sorensen, WSU science writer

Jason GerstnerSPOKANE, Wash. – Washington State University researchers have seen how a particular gene is involved in the quality of sleep experienced by three different animals, including humans. The gene and its function open a new avenue for scientists exploring how sleep works and why animals need it so badly. » More …

WSU geneticist helps solve mystery of Arctic peoples

By Eric Sorensen, WSU science writer

omar cornejoPULLMAN, Wash. – With help from a Washington State University population geneticist, Danish researchers have concluded that North America and the Arctic were settled in at least three pulses of migration from Siberia. First came the ancestors of today’s Native Americans, then Paleo-Eskimos – the first to settle in the Arctic – followed by the ancestors of today’s Inuit. » More …

Researcher sees survival story in fly’s small genome

By Eric Sorensen, WSU science writer

KelleyPULLMAN, Wash. – Few animals can boast of being as tough as the Antarctic midge. Its larvae develop over not one but two Antarctic winters, losing nearly half their body mass each time. It endures high winds, salt and intense ultraviolet radiation. As an adult, the midge gets by without wings and lives for only a week or so before starting the life cycle all over again. » More …

International team sequences rainbow trout genome

By Eric Sorensen, WSU science writer

thorgaard-80PULLMAN, Wash. – Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how vertebrates evolve. » More …

Nature: Ancient child’s genome sheds light on colonization

Anzick-location-80PULLMAN, Wash. – Mapping the genome of a child from the Clovis period has shown his family is the direct ancestor of roughly 80 percent of present day Native Americans, according to a paper published today in the journal Nature (http://www.nature.com/nature/journal/v506/n7487/full/nature13025.html). » More …
