The science of cells that never get old | Elizabeth Blackburn

What makes our bodies age … our skin wrinkle, our hair turn white, our immune systems weaken? Biologist Elizabeth Blackburn shares a Nobel Prize for her …


  1. Just fast often to protect your telomeres and trigger autophagy, autophagy will clean up those damaged cells that lead to cancer. With no products/treatments to sell it will be a long time before this catches on.

  2. To Bi below:
    These christians have read only ONE book – the unimportant bible – but NEVER ANYTHING outside that.
    If they were to read Karl Marx's "Das Capital" or Dr Peter Singer's "Animal Liberation", then they would truly understand.

  3. These evolutionists have read every book except for the Bible and if they were to read the Bible they would then truly understand. These bodies, earth and universe is just a digital simulation. From a Christian point of view this is amazing but it is nothing compared to what you will receive if you except the Lord Jesus Christ as your Savior and repent of all your sins in His name.

  4. Can someone explain to me my question. (An Unethical Question FOR SCIENCE) Since telomeres gets shorten as dna divides, the telomeres in our sperms/eggs should be technically be new right? Can't we do something about that since we actually produce new full length telomeres in sperms/eggs everyday/month

  5. There is a typo in the title. Because this video is discussing a single type of science, it should say "the science of cells that never gets old." Alternatively, it could read the "sciences of cells that never get old."

  6. Dr. Blackburn first came to my attention in a documentary titled Stress: Portrait of a Killer, which mainly focused on Robert Sapolsky's work, but included a segment on Dr. Blackburn and exactly the study with Eliza Eppel that she mentions here. For those interested in finding the full effects of stress on our lives and health, I heartily (no pun intended) recommend that video as well.

  7. Damn, that means my telomeres are not looking too hot right now. xD this was so interesting though. I have always heard that stress can shorten your lifespan, but I never knew why or if it was even true! I'm a psychology major so this really got me thinking…and I realized that NOW IM STRESSING ABOUT WEARING DOWN MY TELOMERES BY STRESSING. XDD
