New test scans all genes simultaneously to identify single mutation causing child's rare genetic disease
Sequencing the DNA of children with mystery genetic disorders produced a definitive diagnosis in 40 percent of one hospital’s most complex cases -- a quantum leap from the field’s 5-percent success rate 20 years ago.
Women driven by status, wealth rather than wanting babies, study suggests
Women are more driven to seek wealth and status than they are to reproduce, a new study suggests. The research says although low fertility may seem to go against traditional ideas about evolutionary success, a woman will delay and reduce her fertility if it brings her opportunities for higher status. The findings are based on interviews with 9,000 women in Mongolia, a country that underwent a sudden transition from a Soviet-style state to mass privatization.
Scale of declines of UK migratory birds wintering in Africa revealed
The migration of millions of birds across the face of the planet is one of nature's greatest annual events. Every spring some species move in one direction, while every autumn those same species move in the opposite one, very often linking continents. Although these migration patterns are as regular as the seasons, monitoring is revealing that, for some species, fewer birds are making the journey each season as the populations of these birds, including species nesting in the UK, are declining rapidly.
