| | | Leading Edge brings you the latest news from the world of science. Geoff Watts celebrates discoveries as soon as they're being talked about - on the internet, in coffee rooms and bars; often before they're published in journals. And he gets to grips with not just the science, but with the controversies and conversation that surround it.

"If what interests you are new and exciting ideas, it's science you should be turning to. And whether it's the Human Genome Project or the origins of the Universe, Leading Edge is the place to hear about them."

All sorts of animals – fish, birds and mammals – forage in groups.
Safety in numbers
It's safer staying in a group as there's less chance of being picked off by predators. And it's easier to find food when there's a whole bunch of you looking.
New territory
But what causes the herd to move on? Which animal makes the decision, and why?
The boss
One plausible explanation would be that each group has a leader - one member who makes the decision
'time to go'!
Research
Zoologist Sean Rands of the Natural Environment Research Council has tested this idea, but not by donning his anorak and getting wet in the countryside.
Join Geoff Watts to find how.
