Films / Research, review and historical scholarship

A paper is not
the whole experiment.

What happens to a lung cell when an airway reopens? Why did two embedding materials refuse to form a sectioning block? What did Cairo's historical pharmacists do to keep medicines usable? Each short film begins with a question like these and links back to the relevant experiment, publication or historical source.
