During the first part of the pandemic I watched the lectures for the Introductory Biology course [1] from MIT OpenCourseWare. I cannot recommend those highly enough!

Almost every lecture brought up and highlighted something really cool and fascinating. Like how RNA sequencing over the last couple of years has gone from expensive to almost free, and what its uses are. Or time-lapse of bacteria adapting to antibiotics. Or just the first lecture showing a video of someone sticking a syringe into a cell. There were even some labs that could be done via a normal web browser.

For me this was so much more engaging than the biology I was thought in high school, where we mostly learned things from outdated books.
