The 2006 Ig Nobel Prize Winners

Teenager repellent wins award

A device that repels teenagers has won the peace prize at this year's Ig Nobels - a spoof version of real Nobel prizes.

Welshman Howard Stapleton's device makes a high-pitched noise inaudible to adults but annoying to teenagers, reports the BBC.

Other winners included a US-Israeli study into how a finger up the rectum cures hiccups and a report into why woodpeckers do not get headaches.

All the research is real and published in often prestigious journals.

Unlike the recipients of the more illustrious awards, Ig Nobel winners get no cash reward.

Nevertheless eight of the 10 winners this year paid their own way to receive their prizes in Cambridge, Massachusetts.

Marc Abrahams, editor of science humour magazine Annals of Improbable Research, which co-sponsors the awards, said: "The prizes are intended to celebrate the unusual, honour the imaginative - and spur people's interest in science, medicine and technology."

The winners are allowed to give a one-minute acceptance speech, the time policed by a loud eight-year-old girl.

This year's winners included:

Maths: How many photos must be taken to almost ensure no-one in a group shot has their eyes closed, by Nic Svenson and Piers Barnes

Ornithology: Why woodpeckers do not get headaches, by Ivan Schwab and the late Philip RA May

Nutrition: Why dung beetles are fussy eaters, by Wasmia al-Houty and Faten al-Mussalam

Acoustics: Why the sound of fingernails scraping on blackboards is so annoying, by D Lynn Halpern, Randolph Blake and James Hillenbrand

Medicine: The Termination of Intractable Hiccups with Digital Rectal Massage, by Francis Fesmire, Majed Odeh, Harry Bassan and Arie Oliven.

The 2006 Ig Nobel Prize winners were awarded on Thursday night, October 5, at the 16th First Annual Ig Nobel Prize Ceremony, at Harvard's Sanders Theatre.

The ceremony was webcast at www.improbable.com. Recorded video will be posted here soon.

Two days after the ceremony -- on Saturday, October 7 -- the new winners will give free public lectures at the Ig Informal Lectures.
