The Isles of Scilly is an archipelago of approximately 150 islands located roughly 27 miles southwest of the westernmost point of England (Land's End). The islands are an eroded remnant of granite rock that intruded into the Earth's crust from deeper underground. Humans have inhabited the islesfor more than 4,000 years.

'TRUE FACTS'

The Web site and search engine Yahoo! was originally called "Jerry and David's Guide to the World Wide Web," after its two founders, Jerry Yang and David Filo. According to company lore, Yahoo! is an acronym for "Yet Another Hierarchical Officious Oracle," though Yang and Filo say theychose the name because they liked the general definition of a yahoo: a rude, unsophisticated, uncouth person.

OUR IGNOBEL HISTORY

In 2002, three scientists at the University of Stockholm in Sweden sought to answer the burning question: Do chickens prefer beautiful people?

They exposed six chickens (Gallus gallus domesticus) trained to peck at a computer screen to photos of seven human faces - men and women of varying degrees of attractiveness.

The scientists noted how often the chickens pecked at each picture, then compared this behavior with 14 college students who were asked simply to pick pictures, not peck at them.

The chickens and the students tended to choose the same beauteous faces of the sex opposite their own, proving (sort of) that chickens do indeed prefer beautiful people.

For their work, the Swedish scientists won the 2003 Ig Nobel Prize for Interdisciplinary Research.

THE AIR UP THERE

If you fret about the general healthiness of cramming together sneezing, coughing passengers in an airplane, this news might help you breathe a bit easier: Purdue University scientists are developing a system to locate and identify passengers who are releasing germs - or worse - inside airline cabins.

"The goal is to be able to track the source if a person released a biological agent, such as anthrax, or inadvertently released a pathogen, such as pandemic flu, by sneezing," said Qingyan Chen, a professor of mechanical engineering at Purdue.

In a paper to be published in the journal Indoor Air, Chen and colleagues describe a system that uses sensors placed throughout an airliner's cabin and mathematical models to trace the source of detected airborne substances back to an area the size of a single airline seat.

Researchers have tested their ideas by re-creating a commercial airliner's passenger compartment, complete with rows of seating. The system appears to work, but it is currently too slow for practical use, requiring several days to crunch the data and determine the source.

The goal, of course, is to perfect a system that works in real time and pinpoints a contaminant's source before a plane lands.

Until then, hold your breath.
