Scientists in the 20th century were looking for a way to use radiation that helped humanity instead of hurting it. So they decided to blast food with radiation to see if they could make it better. Here's how that worked out...

Turns out training people to perform surgery is actually quite difficult, so some scientists decided to copy animal trainers to see if it made a difference...

Munchausen By Proxy Syndrome (or, more correctly, Factitious Disorder Imposed on Another) is a condition wherein a person does almost everything they can to make someone else appear seriously ill.
