... developed genetic techniques that enabled them to label
neural stem cells in adult mice that are responding to Shh signaling at any time point so they could study which stem cells respond to Shh. Other researchers had shown that transient bursts of Shh signaling caused neural stem cells to proliferate and...

the protein for delivery to the cell surface, Shikano added randomly generated eight-building-block long tags onto one end of a particular protein. He then evaluated whether the protein ended up on the cell surface instead of remaining inside the cel...

What do 'ecolabels' tell about food?
Chances are you have seen a "dolphin-safe" label
on a tuna fish can at the supermarket. You may be seeing more labels like it, and not just on tuna fish cans. In a Nutrition Today article on ecolabels, William Lockeretz, PhD, and Kathleen Merrigan, PhD, both professors at the Friedman School of Nu...

Researchers call for expanding the repertoire in studying birdsong

songbirds as either closed-end or open-ended learners, depending on when they learned their song repertoires. The assumption has been that most species, with a few exceptions, learned their songs early in life. More recent research, Beecher and Bre...
