A Canadian expedition in the 1960s collected soil on Rapa Nui, and a bacterium in it made the molecule. It became a transplant drug, then a lab favorite in aging research.

The Trail

  1. “rapamycin easter island discovery” (google.com)
  2. Sirolimus (en.wikipedia.org)
  3. Easter Island (en.wikipedia.org)

    rapa nui → rapamycin

  5. Surendra Nath Sehgal (en.wikipedia.org)

    supposedly kept the culture alive in his home freezer after the project was shut down
