Bien que les réserves de sables bitumineux du Canada soient considérables, les technologies actuelles de séparation et de valorisation pourraient limiter le potentiel des sables bitumineux de devenir une source importante de pétrole en Amérique du Nord. Les usines de demain devront tenir compte des coûts environnementaux et ne pourront plus compter sur des sources […]

Randy Mikula: Trading Water for Oil - Tailings Management in Surface-Mined Oil Sands About 12 barrels of water are needed to produce each barrel of bitumen from surface mined oil sands. Most of this water can be recycled, but a significant portion forms a mud-like suspension called fluid fine tailings. These tailings are stored in […]

Dr. Chris Metcalfe: What are we flushing down the drain?

Dr. Kevin Englehart: Bionic Limbs - from science fiction to reality Advances in capturing and processing the signals from undamaged nerves are opening the door to prosthetic devices that permit a stunningly fine level of control. Today’s speaker will explain the scientific and engineering basis of these revolutionary new human-machine interfaces and present a short […]

Dr. Bryan Kolb: Understanding the plastic brain Although once considered a static organ, the brain continually rewires its structure and function to adapt to very different environmental, cultural, and developmental conditions. Consider, for example, the very different demands on the brain of an airline pilot, lawyer, musician, and pipe fitter. Each has a complex set […]

Dr. Jeffrey Dahn: Are Batteries and Fuel Cells ready for All-Electric Vehicles? Hybrid electric vehicles have arrived, but they lack a substantial all-electric range. The anticipated next generation of “plug-in” hybrids, however, will have batteries that can deliver up to 60 km of all-electric driving. They will potentially eliminate the consumption of gasoline on short […]

Dr. Bridget Stutchbury: When the canary dies Migratory songbirds are experiencing one of the most spectacular declines in numbers of all animal species.

Dr. Victoria Kaspi: The Violent High Energy Universe A glance at the night sky during a quiet walk in the dark countryside suggests that our cosmos is calm and largely unchanging. However, X-ray space telescopes reveal a radically different Universe – one of enormous thermonuclear explosions, jets spewing from super massive black holes, and giant […]

Francis A. Plummer: University of Manitoba and National Microbiology Laboratory (Winnipeg), Public Health Agency of Canada In recent decades, more than 40 new or newly recognized diseases have emerged, largely from animal populations, to become local challenges or major pandemics like swine flu. At the same time, familiar diseases have evolved antibiotic resistance or other […]
