Fish choose Their Leaders By Consensus

ScienceDaily (Nov. 14, 2008) — Just after Americans have headed to the polls to elect their next president, a new report in the November 13th issue of Current Biology, a Cell Press publication, reveals how one species of fish picks its leaders: Most of the time they reach a consensus to go for the more attractive of two candidates.


"It turned out that stickleback fish preferred to follow larger over smaller leaders," said Ashley Ward of Sydney University. "Not only that, but they also preferred fat over thin, healthy over ill, and so on. The part that really caught our eye was that these preferences grew as the group size increased, through some kind of positive social feedback mechanism."

Mysterious glowing aurora over Saturn confounds scientists

By Daily Mail Reporter

A stunning light display over Saturn has stumped scientists who say it behaves unlike any other planetary aurora known in our solar system.

The blueish-green glow was found over the ringed planet's north polar region just like Earth's northern lights.

It was discovered by the infrared instruments on NASA's Cassini spacecraft.

'We've never seen an aurora like this elsewhere,' said Tom Stallard, a scientist working with Cassini data at the University of Leicester.

'This aurora covers an enormous area across the pole. Our current ideas on what forms Saturn's aurora predict that this region should be empty, so finding such a bright aurora here is a fantastic surprise.'
