It's discouraging to make a mistake, but it's humiliating when you find out you're so unimportant that nobody noticed it. (Chuck Daly)

Stress Grays Our Hair

4.5 minutes

The leading cause of premature graying of hair in humans is teaching A&P. Not really. Perhaps. Just seeing if anybody actually reads these notes! But we do know that stress can do it. Here's the mechanism...

  • Stress speeds up hair greying process, science confirms: Fight-or-flight response nerves pump out hormone that wipes out pigmentation cells (news story)
  • How the stress of fight or flight turns hair white (editorial summary from Nature)
    Hyperactivation of sympathetic nerves drives depletion of melanocyte stem cells (research article from Nature)
  • The five: factors that affect early greying (news feature)

New Type of Immune Cell

6 minutes

We know about B lymphocytes and T lymphocytes, right? What happens when we find a combination lymphocyte? A "CatDog" of lymphocytes?

  • Novel Type of Immune Cell Discovered in Type 1 Diabetes Patients (news feature)
  • A Public BCR Present in a Unique Dual-Receptor-Expressing Lymphocyte from Type 1 Diabetes Patients Encodes a Potent T Cell Autoantigen (research article from Cell)
  • CatDog: The Complete Series (DVD set)
