Pronouns light up brain!

New research suggests that pronouns may play a far greater role than simply replacing a proper name in a sentence. A University of South Carolina study suggests that pronouns help keep the brain's complex circuitry and limited memory system from being overloaded.

Fibrin may be new target for Alzheimer's drugs

Despite the rapid rise of Alzheimer's disease - the Alzheimer's Association predicts as many as 7.7 million cases by 2030 - there are no preventative treatments available, few in the pharmaceutical pipeline, and those drugs being developed all share the same two molecular targets.
