“Science” Explained by John Oliver

“[Fill in the blank] Shown to Cause [fill in the blank scary disease] according to a new study.”

Great show May 8, 2016, Last Week Tonight with John Oliver: https://www.youtube.com/watch?v=0Rnq1NpHdmw that does a good job explaining what those news items on "a study says..." mean - generally nothing as the results touted are misstatements of what's really been found in a limited study.
