Japan now needs increased generating capacity fast. Toshiba's 4S (Super Safe Small and Simple) reactor cores are ... Continue Reading
Researchers at the University of Michigan Medical School recently showed how the plasticity of the brain allowed mice to restore critical functions related to learning and memory after the scientists suppressed the animals' ability to make certain new brain cells, says Geoffrey Murphy, Ph.D. After halting the ongoing growth of key brain cells in adult mice, the researchers ...

To what extent does the harmfulness of an anticipated outcome affect our brain's event monitoring system? Not at all, revealed a new study published in the February 2011 issue of Elsevier's Cortex: the reaction is the same, regardless of how scary the anticipated event is. Our brains are able to adapt to the unexpected using an built-in network that makes predictions ... Continue Reading

The findings suggest that the brain evaluates memories during sleep and preferentially retains the ones that are most relevant. Humans take in large amounts of information every day. ...
