University of Alberta researchers have unearthed a mysterious link between bones of an ancient lizard found in Africa and the biggest, baddest modern-day lizard of them all, the Komodo dragon, half a world away in Indonesia. Biologists Alison Murray and Rob Holmes say the unique shape of the vertebrae links the 33-million-year-old African lizard fossil with its cousin the Komodo, which has only been around for some 700,000 years. "The African fossil was found on the surface of a windswept...

Tyrannosaurus rex was far from a plodding Cretaceous era scavenger whose long tail only served to counterbalance the up-front weight of its freakishly big head. T. rex's athleticism (and its rear end) has been given a makeover by University of Alberta graduate student Scott Persons. His extensive research shows that powerful tail muscles made the giant carnivore one of the fastest moving hunters of its time. As Persons says, "contrary to earlier theories, T. rex had more than just junk in its...

A University of Alberta geomicrobiologist and his PhD student are part of a research team that has identified phosphorus as the mystery ingredient that pushed oxygen levels in the oceans high enough to establish the first animals on Earth 750 million years ago. By examining ancient-ocean sediments, Kurt Konhauser, student Stefan Lalonde and other colleagues discovered that as the last glacier to encircle Earth receded, leaving behind glacial debris containing phosphorus that washed into the...

If you're having a bad day, you may want to stay away from listening to commercials for Lululemon or Coca Cola. Or from any retailer or merchandise whose name bears a similarly repetitive phonetic sound.

University of Alberta researcher Lori Friesen's classroom assistants are very attentive, love to listen to children read and can keep their composure in a classroom full of energetic Grade 2 students. However, her assistants are more likely to lick the students' faces than give them a gold star. Friesen's says her work with her "literacy dogs," Tango and Sparky, in one city-area classroom yielded some highly positive successes for the children and her research. In Friesen's research, children...

In fact researchers...

King and Zayas developed a drug that, when inhaled, would reduce or eliminate the amount of...
