September 28 · 8 minWhatever happened to acid rain? - Joseph Goffman
Discover what causes acid rain, and how scientists were able to largely eliminate this major environmental threat. -- In 1963, scientists studying Hubbard Brook Experimental Forest made a shocking discovery.

And what could be done to stop it? Joseph Goffman details how scientists transformed this major threat into a minor issue. Lesson by Joseph Goffman, directed by Nick Hilditch.

September 27 · 9 minIs marijuana bad for your brain? - Anees Bahji
Explore how marijuana’s two main active compounds, THC and CBD, affect your brain and body, and what risk factors to watch out for. -- In 1970, marijuana was classified as a schedule 1 drug in the United States: the strictest designation possible, meaning it was completely illegal and had no recognized medical uses.
