People who volunteer for medical research usually expect to remain anonymous. That includes people who donate their DNA for use in genetic studies.

Flu viruses can tell time. Sort of. And the viral clock-watching could provide a new way to fight the flu.
A study in Cell Reports describes how researchers tapped into the flu's internal clock as they search for ways to keep the virus from spreading.
There's no doubt that the plague has staying power.
The deadly bacterium has probably been infecting people for 20,000 years. And, its genes have hardly changed since it killed nearly half of Europe's population during The Black Death.
Now microbiologists have evidence that strains of the plague may be able to reactivate themselves and trigger new outbreaks — even after lying dormant for decades.
