Quiz Answers

1) – C) A boar gives 4000 Cal/Kg, a mammoth 2000 Cal/Kg, a human 1300 Cal/Kg. It seems that cannibalism among Paleolithic people was ritualistic rather than nourishing. With us facing imminent food shortages, this is probably good news.

2) – C) A kidney stone, though nobody knows why. But whatever the science, if it works, do it; get off to your local funfair. At least the fun might offset the excruciating pain.

3) – B) Female fruit flies give off a potent pong to lure males; and perhaps to repel wine connoisseurs, though that may be an incidental benefit.

4) – A) Spittle contains the enzyme amylase, which cleaned so well, it will undoubtedly be developed into a polishing agent, sold in shops, and we, like fools, will buy it. It’s enough to make you spit.
We all love inventive minds
The Ignobel Prizes were particularly thrilling last September, because the University of Brighton was among the winners. The Ig Nobels are awarded to research ‘that makes you laugh, then makes you think’. They celebrate the farthest fringes of scientific research because even there, where weird stuff happens (see below), there may be seriously useful results; please read the full report HERE.
