PARIS - There is the riddle of the Bermuda Triangle. The unresolved identity of Jack the Ripper. The enigma of how the Universe developed beyond a quark-gluon soup following the Big Bang. And then there is the Sheepdog Mystery. Credit: Getty Creative A puzzle that has niggled mathematical minds for years, the Mystery is this: how does a single dog get so many selfish sheep to move so efficiently in the same direction? The answer, revealed on Tuesday in a journal published by Britain's prestigious Royal Society, is that sheepdogs cleverly follow a simple rulebook. Researchers fitted highly accurate GPS tracking devices into backpacks that were then placed on a trained Australian Kelpie...

Spritzing dogs with a "pig perfume" helps prevent them from barking incessantly, jumping frantically on house guests and from engaging in other unwanted behaviors, according to new research.

One spritz of the pig perfume seemed to do the trick in an instant without harming his dog.

Science Exonerates Theft-Accused Magpies

PARIS - Magpies, black-and-white birds which for generations have been known as jewelry thieves, are in fact wary of shiny objects, a myth-busting study has claimed. Credit: Getty Creative In a series of experiments, British animal behaviorists found that, far from being kleptomaniacs, the birds were in fact fearful of unknown objects. The team had arranged a selection of objects, shiny and dull, at different sites on the University of Exeter campus and observed the reaction of wild and captive magpies. Items included metal screws and foil rings -- half of them painted blue with matt paint and the rest left shiny -- and a piece of aluminum foil, with piles of nuts in between. "Magpies...

Our species caused 322 animal extinctions over the past 500 years, with two-thirds of those occurring in the last two centuries, according to a paper published in a special issue of the journal Science this week. West African Black Rhinoceros (Extinct). Credit: Flickr/Arno Meintjes Wildlife Many animals are threatened with human-caused extinction now, with researchers expressing particular concern over amphibian and invertebrate (creatures without a backbone) losses. Numbers of the latter group have nearly halved as our population doubled in size over the past 35 years. Ecologists, zoologists and other scientists believe that, without urgent steps to stem the losses, we are facing global...
