|Early life stress affects cognitive functioning in low-income children
||About a fifth of all U.S. children live in poverty. These children are more likely to experience learning and cognitive delays. Researchers have tried to determine causes for this disparity, with recent work identifying the hormone cortisol as a possible reason because of its ability to pass the blood-brain barrier. Cortisol is one of the [...]

|Individuals with social phobia have too much serotonin — not too little
||Previous studies have led researchers to believe that individuals with social anxiety disorder/ social phobia have too low levels of the neurotransmitter serotonin. A new study carried out at Uppsala University, however, shows that the situation is exactly the opposite. Individuals with social phobia make too much serotonin. The more serotonin they produce, the more [...]

|Recalling happier memories can reverse stress-induced depression
||MIT neuroscientists have shown that they can cure the symptoms of depression in mice by artificially reactivating happy memories that were formed before the onset of depression. The findings, described in the June 18 issue of Nature, offer a possible explanation for the success of psychotherapies in which depression patients are encouraged to recall pleasant [...]

|What don’t you understand about yes and no?
||The words ‘yes’ and ‘no’ may seem like two of the easiest expressions to understand in any language, but their actual behavior and interpretation are surprisingly difficult to pin down.

|Men get ahead by chatting before negotiations
||Whether sealed with a handshake, a million-dollar contract, or a string of curses, every business deal is a reflection of trust. Both parties trust that the other will hold up their end of the bargain.

|Parents’ beliefs about their children make siblings different
||They grow up in the same home, eat the same food, share the same genes (and sometimes the same jeans), but somehow siblings are often no more similar than complete strangers.
