Researchers Identify 104 High-Risk Genes for Schizophrenia

A research team led by Vanderbilt University scientists has identified a set of high-confidence risk genes for schizophrenia. The team’s results support the view that schizophrenia is a developmental disease, one which potentially can be detected and treated even before the onset of symptoms. Wang et al predicted a set …

Study: Neanderthals, Woolly Mammoths Shared Genetic Traits

study-neanderthals-woolly-mammoths-shared-genetic-traits

Neanderthals and woolly mammoths (Mammuthus primigenius) co-existed in similar geographic and environmental European settings during the Middle and Upper Pleistocene epochs and both were direct descendants of African ancestors, although both fully evolved and adapted in Europe during the Middle Pleistocene. A new study, published in the journal Human Biology, …

Scientists Sequence Genomes of English Walnut and Its Wild Relative

A research team led by scientists from the University of California, Davis, has used a unique approach to sequence the genomes of the English walnut (Juglans regia) and its wild North American relative, the little walnut (Juglans microcarpa), by tapping into the capabilities of two state-of-the-art technologies: long-read DNA sequencing …

Researchers Identify New Gene Regions Associated with Insomnia

Insomnia is a common disorder linked with adverse long-term medical and psychiatric outcomes. It affects 10-20% of adults, and several twin and family studies suggested that about a third of the risk of insomnia is inherited. Now a team of scientists from the University of Exeter and Massachusetts General Hospital …
