Neuro News Nanos

Here are this morning’s:

* A roundup on group psychology — great primer — “Groups can kill our creativity, inspire us to work harder, allow us to slack off, skew our decision-making and make us clam up.”

* Another long discourse on “the age of enhancement” — drugs to change everything about us — humans and voles in love (not with each other, thankfully)

* Good neighbors need good fences — a mathematical model — violence is most likely to erupt in areas with poorly-defined boundaries between large and culturally different groups

* The seven-year itch cuts our friends in half — personal network sizes remained stable, but many members of the network were new — our choice of friends is limited by opportunities to meet

* Studying you by cell — first study, phones of 94 students and staff at MIT, using blue-tooth technology and phone masts — participants tended to overestimate how much time they spent with friends and underestimate how much time they spent with non-friends
