Researchers transfer DNA from the long-vanished Tasmanian tiger into a mouse. The finding shows how lost information about species from the past can be retrieved and also provides a glimpse into how long-gone creatures may someday get a second chance at life.

Researchers often rely on mice to study a host of genetic diseases in the lab. That's not a satisfactory approach for many neurodegenerative illnesses, which involve cognitive and behavioral symptoms that don't map easily from human patients to rodents.

Now, in a development that opens the door to modeling such illnesses in primates, researchers have created the first transgenic monkeys with neurological signs of Huntington's disease.
