A new study shows that methane leaks in drinking water wells around shale-gas wells in Pennsylvania and Texas come from failures in the integrity of gas well construction, and not from the drilling or hydraulic fracturing. The authors developed a new technique to look for the concentration of noble-gas isotopes in drinking-water samples to determine […]
‘Vegetative’ patient follows the plot of an Hitchcock movie
Some patients thought to be in a vegetative state can have conscious experiences similar to healthy people, a new study shows. Researchers used fMRI to record the brain activity of 2 brain-injured patients and 12 healthy participants while they watched a 8-minute clip of an Alfred Hitchcock movie. One of the brain-injured patients, a man […]
Genomics: the power & the promise – Early bird registration
Genome Canada and The Canada Gairdner International Awards are hosting a conference and gala dinner event exploring the theme “Genomics: the Power & the Promise“. The conference will explore how genomics has affected our daily lives, as well as the impacts of environmental factors on human health. Held at the Ottawa Convention Centre between November 24 – 26, 2014, the […]
New Pterosaur – Avatar style
Researchers have found deposits of a new species of pterosaur, a flying reptile that lived about 120 million years ago. This new species was named Ikrandraco avatar for it’s similarities to the ‘ikran’ flying creatures in the 2009 Avatar movie and to a dragon (draco). The fossils were found in Northeastern China. Original research paper published […]
How to have sex without hurting your back
Contrary to popular belief, spooning is not always the best sex position for those with a bad back. Using infrared and electromagnetic motion capture systems – like those used in the creation of video games – scientists tracked how 10 couples’ spines moved when attempting five common sex positions. They found that sex positions that are […]
Cannabis impacts on teenagers
Daily users of cannabis before age 17 are over 60% less likely to complete high school or obtain a degree compared to those who have never used the drug, a new review of literature shows. The authors reviewed 290 reports on cannabis use in teenagers published since 2004. The authors conclude that adolescent cannabis use […]
Long term use of pills for anxiety and sleep problems and Alzheimer’s
Prolonged use of benzodiazepines, drugs useful to treat anxiety and insomnia, is linked to higher risks of developing Alzheimer’s disease, a new study indicates. Researchers looked at the benzodiazepine drug use in 1,796 elderly patients suffering from Alzheimer’s disease living in Quebec and compared them to a control group of elderly without diagnosed cognitive problems. They […]
Physicians in Canada 2013
How many doctors are currently practising in Canada and how much are they getting paid? How many of them received their medical training outside of Canada? Are more women entering the physician workforce? A new CIHI report, available upon request, tackles these questions. Original report published by the Canadian Institute for Health Information (CIHI) on September 9, 2014.
Resistance of the boreal forest to fire
A new study shows that the boreal forest could be more resilient to forest fire than previously thought. Using climate projections, scientists estimate that forest fire in the Boreal forest in Canada will be bigger and happen more frequently by the end of the 21st century. However, a careful study of the past 200 years […]
Calculating the impact of a “Green Revolution”
New research suggests that improving crop yields has reduced carbon emissions and land use worldwide, but that this might not be the case in the future. The “Green Revolution” refers to the use of fertilizers, pesticides and other agricultural technology to increase crop yields. Previous studies have shown that rather than decreasing the amount of land […]
Helping grad students prepare for life beyond the lab
Graduate students in Ontario have a new tool to help them prepare for life beyond the lab. MyGradSkills.ca is a new website available to any Ontario graduate student via their university e-mail account. It offers 18 short, self-paced training units on topics such as how to write a resume, how to conduct a job search, the […]

The Government of Canada, through Grand Challenges Canada, announces seed funding Sept. 8 for 22 projects submitted by innovators worldwide and designed to improve health in the developing world. Examples include: A device that converts sound into symbols for display on Google Glass, a tablet or laptop, captioning conversations in real-time for deaf people A […]
Archerfish are more skillful than previously thought
Archerfish use jets of water to shoot down insects for dinner, but new research shows they are more skilled at this than previously thought. Researchers trained archerfish to hit targets ranging in height from 20 to 60 centimeters from a precise location, and monitored how they produce the jet. They found that the fish adjust […]
Colossal fossil: 26 meter dinosaur discovered
International scientists have found a new species of dinosaur in Argentina, named Dreadnoughtus, which may represent one of the most complete examples of gigantic titanosaurian sauropod dinosaurs ever discovered. It lived in the southern continents over 66 million years ago, and was one of the biggest creatures ever to walk the Earth. Dreadnoughtus was the most massive land […]
Light-scattering crystals found in Canadian fossil weevils
Scientists have found unique light-scattering crystals in a 700,000-year-old fossilized bug from Gold Run, Yukon. Modern weevils also produce such crystals, but until now not much was known about their evolution. The crystals exploit quantum phenomena to shine bright red and green when examined closely, but from afar the colours blend to produce a muddy brown […]
Dieting? Do whatever works for you
A new meta-analysis of dozens of “brand-name” diets finds that while most are better than no diet at all, there is not much difference between them. The study looked at 48 randomized trials containing a total of nearly 7300 overweight individuals. In terms of amount of weight lost, low-carbohydrate diets give a slight advantage at […]
