that occur as people age, and it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition. The brain uses glucose almost exclusively as a fuel source. It was once generally believed ...

in cardiac function similar to those found in the French family, said first author Peter Mohler, an HHMI postdoctoral fellow at Duke. The researchers then stressed the mice with epinephrine -- inducing a "fight-or-flight" response -- and found that...
