Coffee or Beer for Telomere?

    A new study shows that telomeres–the ends of chromosomal DNA–are affected differently by espresso and beer.

    Researchers at Tau’s Blavatnik School of Computer

     

    Science and Columbia University found that coffee and beer have

     

    opposite affects on telomeres—the end points of chromosomal

     

    DNA, implicated in aging and cancer.  Telomeres keep replicating

     

    but get shorter each time until they finally become too short and

     

    die.  Aging.  There’s aging for ya. Except cancer cells that can

     

    replicate forever.  After exposing yeast cells to different

     

    environmental factors, scientists found that espresso shortened

     

    telomeres and ethanol lengthened them.   They say they still need

     

    to do more research and see if the same is true for human cells.
