Gene-edited stem cells help geckos regrow more perfect tails
Regenerating body parts is never easy. For instance, some lizards can grow back their tails, but these new appendages are pale imitations of the original. Now, genetically modified stem cells…
DNA from mysterious Asian mummies reveals their surprising ancestry

A blood test may help predict recovery from traumatic brain injury
Elevated blood levels of a specific protein may help scientists predict who has a better chance of bouncing back from a traumatic brain injury. The protein, called neurofilament light or…
Ripples in rats’ brains tied to memory may also reduce sugar levels
Ripples of nerve cell activity that lock in memories may have an unexpected job outside of the brain: Dropping blood sugar levels in the body. Just after a burst of…
How Hans Berger’s quest for telepathy spurred modern brain science
A brush with death led Hans Berger to invent a machine that could eavesdrop on the brain. In 1893, when he was 19, Berger fell off his horse during maneuvers…
