How do we build a sustainable Arctic fishery?
September 23, 2016Scientists believe the detection of earthquake-like seismic activity on Mars could be another sign of life.Recent research by an international team of scientists that included Brock University geologist Nigel Blamey suggests that hydrogen gas arising from ‘Marsquakes’ could help sustain life on the Red Planet.Through their analysis of rocks in Sudbury, Scotland and South Africa, the three-member group found that friction occurring during an earthquake produces hydrogen.“Seismic activity has been detected on Mars,” said Blamey, assistant professor in the Department of Earth Sciences. “The question was, can earthquakes on Earth and Mars have anything to do with hydrogen generation, which could then act as an energy source for bacteria? The answer is yes.”Read the full article here.
September 21, 2016An Ontario university has cut its greenhouse gas emissions -- not to mention its air conditioning bill -- using a relatively simple technology.The University of Guelph built a 30-metre-high tank that cools 22 million litres of water each night. The water is piped around campus during the day, cooling classrooms, offices and labs.The thermal energy system cost about $15 million to build but the university says it already has saved about $2.5 million on its electricity bills since the system went online earlier this summer.John Kuri, who works for the energy consultancy MCW, said the savings come partly from the fact that it takes less energy to cool things at night, and partly from the fact that Ontario electricity is cheaper from 7 p.m. to 7 a.m.Read the full article here.
September 19, 2016If you exercised outdoors this summer, there’s a good chance you cursed the record-breaking heat – and in doing so, you made it feel worse.According to a new study from environmental physiologists at Brock University, the internal monologue running through your head as you struggle through a workout in hot conditions has measurable effects on how well your mind and muscles function. The results add to growing evidence that seemingly immutable physical limits are actually governed by the brain –and that, with some simple changes, we can alter those limits.The study, led by Dr. Stephen Cheung and his student Phillip Wallace, explored the use of “motivational self-talk.” A group of 18 trained cyclists performed a series of tests that included a timed bike ride to exhaustion while maintaining a constant pedalling power, and a battery of cognitive tests in 35 C heat. Half of the group then received two weeks of self-talk training, and then they repeated the same series of physical and cognitive tests.Read the full article here.
