The Ig Nobel Prizes honor achievements that make people laugh, and then think. The prizes are intended to celebrate the unusual, honor the imaginative — and spur people's interest in science, medicine, and technology.

Previous winners have included Andre Geim, who won an igNobel for using superconducting magnets to make a frog float, and then went on to win a Nobel prize in 2010 for his work on graphene.

This year’s winners:

Duration of Urination Does Not Change With Body Size

Pain Over Speed Bumps in Diagnosis of Acute Appendicitis: Diagnostic Accuracy Study

People who drive themselves to hospital and go over speed bumps may be able to diagnose appendicitis from the pain it causes.

The high sensitivity of pain over speed bumps gives it a strong “rule-out value” and makes it a useful tool to use in excluding appendicitis and other important abdominal diagnoses. The low specificity, however, means that many patients with pain over speed bumps will not necessarily have appendicitis

Hemolytic Activities of Stinging Insect Venoms

Honey Bee Sting Pain Index by Body Location

There are two studies - the first is the Schmidt pain scale, where Justin Schmidt allowed different insects to sting him. Second is Michael Smith who let bees sting himself if 25 different places to see which are the most/least painful.

From Schmidt's descriptions:

Bald-faced hornet

“rich, hearty, slightly crunchy. Similar to getting your hand mashed in a revolving door.”

Yellowjacket

“hot and smoky, almost irreverent. Imagine WC Fields extinguishing a cigar on your tongue.” Both rate a two.

Bullet ant

“pure, intense, brilliant pain, like fire-walking over flaming charcoal with a three-inch rusty nail grinding into your heel”. Smith

The most painful parts to be stung on: the nostril, the upper lip, the shaft of the penis.
