Log­ging in to SciFinder Scholar today, I dis­cov­ered that CAS has made some inter­est­ing and ele­gant instruc­tional pod­casts.  Exam­ples include: ethanol, nanopar­ti­cle drug deliv­ery, DNA to RNA tran­scrip­tion, nan­otech­nol­ogy for energy, and lessons from Kat­rina.  The videos last from 4 — 6 minutes.
