Stress Greases Your Biological Clocks - Reprise

  Vidcast:  https://youtu.be/QetW5Xs_9Uk   Our cells and bodies work on internal biological clocks which are lubricated for better efficiency by good old fashioned stress.  University of Minnesota biologists now report  this phenomenon in the journal Neuron.   Using a mouse model and tissue cultures of cells, the scientists unraveled the complex blend of signaling proteins that control the clock. They found that stress accelerates the speed of signal processing and improves the robust nature of cellular biologic clocks.   The bottom line is that some stress may well be good for you.  It literally keeps your system on its toes and speeds your reaction time.   Salil Saurav Pathak, Dong Liu, Tianbao Li, Nuria de Zavalia, Lei Zhu, Jin Li, Ramanujam Karthikeyan, Tommy Alain, Andrew C.
