An ancient predator species with agile bodies, saw-like teeth and an insatiable appetite for meat survived a major extinction at a time when distant relatives of mammals ruled the Earth, according to new research by scientists at Cape Breton University and the University of Toronto Mississauga. In a study published in Naturwissenschaften — The Science of Nature, Professors Sean Modesto and Robert Reisz provided evidence that varanopids survived for more than 35 million years, and...

A reptile that lived 275 million years ago in present day Oklahoma is giving paleontologists a glimpse of the oldest known toothache, predating by 200 million years the previous record for the earliest known evidence of tooth decay in a terrestrial vertebrate. The researchers, led by Professor Robert Reisz, who chairs the Department of Biology at the University of Toronto Mississauga, found evidence of bone damage due to oral infection in Paleozoic reptiles as they adapted to living on...

It makes your skin crawl"”a bug that crawls onto your lips while you sleep, drawn by the exhaled carbon dioxide, numbs your skin, bites, then gorges on your blood. And if that's not insult enough, it promptly defecates on the wound-and passes on a potentially deadly disease. Now Jean-Paul Paluzzi, a PhD candidate in biology at the University of Toronto Mississauga, believes that manipulating physiology to prevent the insects from leaving their messy calling card represents the best hope...

When Professor Joel Levine's team genetically tweaked fruit flies so that they didn't produce certain pheromones, they triggered a sexual tsunami in their University of Toronto Mississauga laboratory. In fact, they produced bugs so irresistible that normal male fruit flies attempted to mate with pheromone-free males and even females from a different species-generally a no-no in the fruit fly dating scene. The study, published in the Oct. 15 issue of Nature, points to a link between sex,...

Observing and betting on cricket fights has been part of Chinese cultural tradition since at least the Sung Dynasty (A.D. 960-1278). This ancient practice has resulted in quite a detailed list of characteristics that Chinese practitioners think make for champion fighters. "Because money was involved, there was a strong incentive for the practitioners of this sport to observe their cricket fighters closely," says Kevin Judge, a biology postdoctoral researcher at University of Toronto...
