McGill researchers have found that a good dose of motherly love may be enough to alter our genetic code, leaving us less fearful and stressed out in later life. If the finding is confirmed it could lead to dramatic new insights into the effects of upbringing and life experiences on a vast range of medical conditions, including obesity, diabetes and depression. The study, by Moshe Szyf, Michael Meaney, Ian Weaver and their team at McGill, is published in the Journal of Neuroscience.
A McGill- and Harvard-sponsored conference held recently in Boston brought together about three dozen dairy researchers, from nutritional epidemiologists to dairy scientists, to discuss the hypothesis that hormones and growth factors in dairy increase cancer risk. Michael Pollak, an oncologist who studies cancer risk and IGF-1 at McGill, was one of the conference organizers.
The country's deep thinkers gather in Montreal this week for a conference marking the Charter of Rights and Freedoms' 25th birthday on April 17. Supreme Court judges from Canada and the U.S., constitutional experts and even the backroom boys who helped draft the law have been invited. Antonia Maioni, director of the McGill Institute for the Study of Canada, is calling the event a "celebration," a review of both the triumphs and questions arising from this pivotal piece of legislation.
The genes associated with a risk of developing type 2 diabetes have been identified. The research, published online in Nature, is the first time the genetic makeup of any disease has been mapped in such detail. It should enable scientists to develop a genetic test to show an individual their likelihood of developing type 2 diabetes. Rob Sladek and Constantin Polychronakos from McGill, along with scientists from Imperial College, London, and other international institutions, believe their findings explain up to 70% of the genetic background of type 2 diabetes.
Science Magazine looks at the International Laboratory for Brain, Music, and Sound Research (BRAMS), a joint project of McGill and Université de Montréal. The members of BRAMS, including McGill's Robert Zatorre, Université de Montréal's Isabelle Peretz and nine other Montreal-based lead investigators, aim to explore music's mysteries. They seek to understand how humans cooperate to perform together, how children and adults learn to play music, and the relationship between music and language. "BRAMS will allow us to use music as a portal into the most complex aspects of human brain function," says Dr. Zatorre.
The decades-long war between brand-name and generic drug manufacturers shows no signs of abating. But with a rapidly aging population and the spectre of new diseases on the horizon, there's new pressure to find a solution soon that can both motivate innovative research and sustain affordable drug prices. McGill's Richard Gold, director of the Centre for Intellectual Property Policy and a professor in IP and common-law property, is interviewed for this story in the Canadian Bar Association's National Magazine.
Victoria Kaspi laughs at the prediction beside her name in the high school yearbook. "My ambition was to be a famous scientist and mother of six." At 39, she's at least halfway there. An astrophysicist at McGill, Kaspi's groundbreaking research tracking pulsar stars has won her many accolades, most recently the CAP Herzberg medal and Steacie Prize, national awards for research excellence.
The United States lags far behind virtually all wealthy countries with regard to family-oriented workplace policies such as maternity leave, paid sick days and support for breast-feeding, according to a new study released by Harvard and McGill University researchers. The study, by lead author Jody Heymann, founder of the Harvard-based Project on Global Working Families and director of McGill's Institute for Health and Social Policy, says, "More countries are providing the workplace protections that millions of Americans can only dream of."
The Harper government is snuggling up too closely to the United States at the expense of Canada's influence in the rest of the world, former prime minister Joe Clark, professor at the Centre for Developing Areas Studies, told a McGill audience on Wednesday. "Mr. Harper and his colleagues are moving away from the central elements of the foreign policy that has been a strength of Canada under both Progressive Conservative and Liberal governments."
A team directed by Michel L. Tremblay at the Cancer Centre at McGill has uncovered the role played by a gene associated with the propagation of breast cancer in two of five affected women. Their study, published in the magazine Nature Genetics, shows that halting the activity of this gene in mice predisposed to cancer slowed the growth of — and in some cases, prevented — tumors.
A strongly worded editorial in the Globe and Mail states that "Quebec's policy is a noble failure. The tuition freeze would melt away if ever the warm light of reason were shone on it." McGill principal Heather Munroe-Blum was interviewed for the editorial.
McGill biology professor Louis Lefebvre and former McGill post-doctoral fellow Daniel Sol conclude that having a large brain relative to body size improves a bird's chances of survival, in a study published in the most recent issue of Proceedings of the Royal Society B. "It's the first time that there is an advantage for having a big brain that's been demonstrated," Lefebvre said.
Daily use of certain antidepressants doubles the risk of bone fractures in adults 50 and older, a McGill study suggests. The new research, led by Dr. David Goltzman, a professor of medicine and physiology and director of the McGill Centre for Bone and Periodontal Research, seems to support earlier studies. The antidepressants studied are a class known as selective serotonin reuptake inhibitors, or SSRIs, which includes such drugs as Prozac and Paxil.
Quebec politicians must rise above partisan interests and agree to end the 12-year freeze on university tuition fees immediately, says McGill University principal Heather Munroe-Blum. The principal presented before the Commission de l'éducation de l'Assemblée nationale du Québec on January 16.
Severe cases of congenital heart disease are on the rise among North American adults, but researchers say that probably means growing numbers of infants born with the condition are surviving into adulthood. "This is a real success story," said Dr. Ariane Marelli, lead author of a new study on the trend and director of the McGill Adult Unit for Congenital Heart Disease Excellence.
