Politics Aside, Counting Crowds Is Tricky

Monday, January 23, 2017

Claims about the size of crowds for both President Trump's inauguration and the protests that followed the day after, are being debated. Scientists struggle with how to do that kind of head count.


Flipping A Switch In The Brain Turns Lab Rodents Into Killer Mice

Thursday, January 12, 2017

When scientists activate hunting circuits in the brains of genetically modified mice, the animals attack insects and even bottle caps as prey. It gives clues to the evolution of hunting in humans.


Brain Area That Recognizes Faces Gets Busier And Better In Young Adults

Thursday, January 05, 2017

From birth through age 30 or so, our ability to recognize faces keeps improving, research shows. At first, kids discern adult faces better than other kids' mugs. Not so after adolescence.
