A team of researchers at the University of Florence in Italy and the University of Connecticut Health Center have used a multidisciplinary approach to provide an unprecedented glimpse of what happens to the heart during an "infarction" -- a heart attack -- by looking at how the attack affects electrical activity and calcium release in heart cells.

Understanding The Link Between Age And Decreased Maximum Heart Rate

New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.


Word of the Day
bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
