A Theory About Why the Powerful Don't Care For the Powerless People sometimes derogate victims in order to maintain a belief in a just world. A new study suggests that this kind of cold-heartedness could also help people focus on the long-run. read more
Genes uniquely expressed by brain's immune cells Investigators have used a new sequencing method to identify a group of genes used by the brain's immune cells -- called microglia -- to sense pathogenic organisms, toxins or damaged cells that require their response. Identifying these genes should lead to better understanding of the role of microglia both in normal brains and in neurodegenerative disorders.
The Mammogram Myth, Alive and Well on "Good Morning America" Good Morning America's Amy Robach announced that the on-air mammogram she had as part of the show's breast cancer awareness promotion, ended up getting her a diagnosis.

'Widowhood effect' strongest during first three months When a husband or wife dies, the surviving spouse faces a higher risk of dying over the next few months as well, according to a new report.
Glowing worms illuminate the roots of behavior Researchers have developed a system to image brain activity in multiple awake and unconstrained worms. The technology, which makes it possible to study the genetics and neural circuitry associated with animal behavior, can also be used as a high-throughput screening tool for drug development targeting autism, depression, and other brain disorders.
Nicotine withdrawal traced to very specific group of brain cells Nicotine withdrawal might take over your body, but it doesn't take over your brain. The symptoms of nicotine withdrawal are driven by a very specific group of neurons within a very specific brain region, according to a report. Although caution is warranted, the researchers say, the findings in mice suggest that therapies directed at this group of neurons might one day help people quit smoking.

Toddlers can learn verbs even in non-social contexts Language acquisition has traditionally been considered a social, interactive process, however new research reveals that toddlers are able to acquire the meanings of words even in "socially impoverished contexts" where social or visual information is absent.
Cognitive scientists ID mechanism central to early childhood learning, social behavior A study provides compelling evidence for a new and possibly dominant way for social partners to coordinate joint attention, key for parent-child communication and early language learning. The findings open up new questions about language learning and the teaching of language. They could also have major implications for the treatment of children with early social-communication impairment, such as autism, where joint caregiver-child attention with respect to objects and events is a key issue.
Gene linked to common intellectual disability Researchers have taken a step forward in unravelling the causes of a commonly inherited intellectual disability, finding that a genetic mutation leads to a reduction in certain proteins in the brain.
Your brain sees things you don't A study indicates that our brains perceive objects in everyday life of which we may never be aware. The finding challenges currently accepted models about how the brain processes visual information.
Impulsivity, rewards and ritalin: Monkey study shows tighter link Even as the rate of diagnosis has reached 11 percent among American children aged 4 to 17, neuroscientists are still trying to understand attention deficit hyperactivity disorder (ADHD). One classic symptom is impulsivity "” the tendency to act before thinking.
