The British Medical Journal special Chistmas Double issue is a treasure. They've published a great collection of scholarly papers. Here are just a few.
There's a study that shows that people tend to put less alcohol in drinks mixed in tall glasses than in short glasses. It's called Shape of glass and amount of alcohol poured: comparative study of effect of practice and concentration (PDF).
Then, there's Epidemiology and prognosis of coma in daytime television dramas (PDF) which found that "The portrayal of coma in soap operas is overly optimistic. Although these programs are presented as fiction, they may contribute to unrealistic expectations of recovery."
And another that found that regular playing of the didgeridoo is an effective treatment for sleep apnoea. That's Didgeridoo playing as alternative treatment for obstructive sleep apnoea syndrome: randomised controlled trial (PDF).
Maybe my favorite, though, is Harry Potter Casts a Spell on Accident Prone Children (PDF), which finds a reduction in the incidence of traumatic injuries in children that coincides with the release of new Harry Potter novels.
