A team of researchers announced at the American Association for the Advancement of Science meeting in San Diego that dolphins may play a significant role in understanding diabetes in humans.  While sleeping dolphins begin to show the type of insulin resistance that marks type 2 diabetes in humans.  But, after waking and eating, they switch back to their normal state.  Dolphin’s apparently use the ability to switch insulin resistance on and off to boost blood sugars levels overnight.  This is advantageous because their large brains need sugar and their diet of fish doesn’t provide for this need.  Scientists speculate there is perhaps a similar switch in humans.
