Inside the Dangerous Mission to Understand What Makes Extremists Tick —and How to Change Their Minds
On a cool winter’s day in early 2014, the American academic Nafees Hamid was invited for tea at the second-story at the Barcelona apartment of a young Moroccan man. It started well enough; they sat down at the kitchen table, chatting amiably in French while two acquaintances of the host sat nearby in the living room. Halfway through the conversation, though, things took a turn. “He started saying things like, ‘Why should we trust any Westerner?’” Hamid recalls. “‘Why would we not kill every one of them? Why should I even trust you—you are an American—sitting here? Why s...

Scientists show how brain flexibility emerges in infants
(University of North Carolina Health Care) Cognitive flexibility, which refers to the brain's ability to switch between mental processes in response to external stimuli and different task demands, seems to begin developing during the first two years of life, which is much earlier than previously thought. UNC BRIC researchers led by Weili Lin, PhD, used magnetic resonance imaging techniques to show the emergence of a functional flexible brain during early infancy.

How Are Dental Abscesses Treated?
Discussion
Dental caries are one of the most common infections. It is usually caused by Streptococcus viridans. Dental caries are also quite preventable with brushing the teeth at least twice a day with a fluoridated dentifrice, use of dental floss, and preventative dental appointments with application of fluoride varnish and sealants as appropriate. Additionally, fluoridation of the community water supply has significantly decreased dental caries and is a very effective public health measure. Fluoride binds within the dental matrix to strength it.
Dental abscesses are usually caused by poor oral hygiene but others are at...

Scientists Are Learning to Read —and Change—Your Nightmares
The scariest dream my now-college-age daughter ever had was the one about the running legs—or, as they became known in our family, The Running Legs, almost audibly capitalized. She was in kindergarten at the time and the dream amounted to little more than an image of a pair of black tights, filled by an invisible lower body chasing her.
It was the first thing she mentioned when she got up in the morning and she brought it up again over breakfast—clearly distressed. We talked about it a bit and I asked her what she thought the legs would have done if they had caught her.
“Bite me,” she answered.
