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.

News Brief: Ancient teeth point to Neandertal relatives
New analyses of some teeth found in Siberia indicate that Neandertal cousins known as Denisovans lived there for at least 60,000 years. That would have had them around the same place as modern humans — and at nearly the same time.

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.
