For more than 40 years, Dr. Jane Goodall has been studying the chimps of Gombe National Park in Tanzania. She was the first to identify their ability to hunt, to use tools and pass culture from generation to generation. Today she spends very little time in Gombe, instead she travels around the world educating the public on chimps and conservation. Dr. Goodall's latest project is a new IMAX film, 'Jane Goodall's Wild Chimpanzees.'
Most people are aware that an asteroid could have been responsible for the downfall of the dinosaurs. But there's a new theory now, that says it wasn't just an asteriod that knocked the dinosaurs out, it may, infact, have been an asteriod that put them on top in the first place. Dr. Hans-Dieter Sues, the Vice-President of Collections and Research at the Royal Ontario Museum, and a professor of zoology at the University of Toronto, is part of the team that developed the theory.
Dr. Elizabeth Simpson, a Senior Scientist in the Centre for Molecular Medicine and Therapeutics at the University of British Columbia, got a nasty shock on entering her lab one day. The mutant mice she was studying had become rodenticidal maniacs. The mice were violently aggressive, attacking their staff and even killing each other. The problem, she's discovered, is a single mutation she thinks might be worth studying as a way to understand the genetics of aggression.
Dr. Khem Jhamandas, a professor from the department of Pharmacology and Toxicology at Queen's University in Kingston, and his colleagues have made a paradoxical discovery that could help those with chronic pain who've developed tolerance to opiate drugs. They've found a very small amount of a drug that usually neutralizes opiates will actually enhance their effects, and reduce tolerance.
Last week we aired a full-length question show, recorded live in Halifax. This week's question is one we didn't have time to air last week.
Leslie Rogers from Halifax asked, "Could the force of the Halifax explosion have pushed all the water out of the harbour?"
For the answer, we went to Dr. Jack Burney a professor in the Biological Engineering department at Dalhousie University
