Scientists Discover New Diabetes Genes

Six variants each add risk for developing the disease

(Newser) - Scientists pooling data from European and US studies have identified six more genes associated with a higher risk of type 2 diabetes, the Guardian reports. The study, published in Nature Genetics, found small but significant connections between the genes and the disease, with certain genetic variants linked to a 10-15%...

Schizophrenia Gene Find Surprises Scientists

Glitches vary from person to person

(Newser) - Scientists have tracked down the genetic roots of schizophrenia, but in a surprising twist researchers found that the genetic errors to blame often vary from person to person, reports the Seattle Post-Intelligencer. The discovery suggests that multiple glitches in the genetic code are behind schizophrenia, with the exact combination unique...

Africans Have Most Diverse DNA

Testing confirms man evolved on continent before migrating

(Newser) - A pair of wide-ranging genetic studies, published yesterday in the journal Nature, back up the idea that humanity first evolved in Africa before migrating elsewhere, Reuters reports. DNA testing of African Americans and European Americans found that people with African roots had much more genetic diversity. Other tests discovered that...

New dating agency plans to use genetics to find right chemistry

(Newser) - The nose knows. A new dating agency aims to use research into body odor to match up singles who just sniff right to each other, the Economist reports. The founder of ScientificMatch.com is drawing on a ten-year-old study that found a genetic reason for why women found the smell...

Study Finds Mutated Genes Raise Autism Risk

Could be 'tip of the iceberg' of gene flaws linked to disorder

(Newser) - Researchers studying the DNA of autistic children have discovered a pair of genetic mutations that raise the risk of developing autism as high as a hundredfold, USA Today reports. The defects in chromosome 16 occur in just 1% of autistic kids, but that figure represents some 10,000 children. A...

First Americans Migrated From Siberia

Research contradicts theory of multiple arrivals from Asia

(Newser) - Native Americans are descended from a single group that migrated from Siberia 12,000 years ago, new genetic research suggests. An alternate theory suggested that Native American ancestors migrated in several waves over land and sea from Asia, but the new study shows that native peoples from all over the...
