Health & MedicineDo mosquitoes love you? Blame your parents
By studying twins, scientists found that how attractive we are to mosquitoes depends partly on our genes. That could lead to better bug repellents.

GeneticsSilencing genes — to understand them
Hijacking a cell process called RNA interference can let scientists turn off a selected gene. Its silencing can point to what genes do when they’re on — and may lead to new treatments for disease.

Health & MedicineMice can teach us about human disease
Humans and mice look and act very differently. But 85 to 90 percent of their genes are the same or quite similar. So an international group of scientists is deciphering the instructions in mouse genes to help us better understand our own.

GeneticsHigh-altitude help from extinct ancestors
The Tibetan plateau is high in altitude but low in oxygen. An unusual version of one gene in Tibetans' DNA helps them survive this environment. And that gene appears to have been passed along from Denisovans, a Neandertal-like ancestor.

GeneticsNewfound DNA ‘enhancer’ behind many natural blonds
Some snippets of DNA other than genes play a role in giving some people of European a golden crown of hair.
