Banana threat: Attack of the clones
Researchers find that disease-causing fungi — all clones of one another — will continue to infect banana plants unless new steps are taken to stop their spread.

Gene editing creates buff beagles
Scientists showed that a potentially useful new gene-editing tool can work in dogs. It created a pair of adorable, muscular puppies. But the goal is to use it for other research purposes.

DNA: Our ancient ancestors had lots more
Ancestral humans and their extinct relatives had much more DNA than do people today, a new study finds. It mapped genetic differences over time among 125 different human groups.

Do 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.
