Toxins in your fries?

Lab studies on animals have proven the carcinogenic properties of acrymalide, but McGill's Dr. Ariel Fenster explains that the animals used in the lab tests were exposed to high doses of acrymalide not comparable to typical amounts ingested by humans.

Do antioxydants really help us live longer?

In the journal PLoS Genetics, biologist Siegfried Hekimi demonstrates that worms that have been genetically modified to be less effective at antioxydation -- the elimination of free radicals -- live just as long as regular worms. One of the modified worms actually lived longer than normal.

Jurassic cluck

Jack Horner, the paleontologist whose career inspired the film Jurassic Park, is funding scientists on a quest he hopes will culminate in a fowl whose DNA has been "reverse-engineered" to make the bird more similar to its dinosaur ancestors. The work is carried out by Hans Larsson, a biologist at McGill University in Montreal, and Mary Schweitzer, a paleontologist at North Carolina University.

Child abuse alters stress-fighting gene, study says

In a study published in the Journal Nature Neuroscience, researchers report that people who were abused or neglected as children showed genetic alterations that likely made them more biologically sensitive to stress. The findings help clarify the biology behind the wounds of a difficult childhood and hint at what constitutes resilience in those able to shake off such wounds.

Guillaume Gervais, physicist

If you imagine a grain of sand and then divide that by a million, you'll have an idea of the size of a nanometer, a measurement of the infinitely small which excites the passions of physicist Guillaume Gervais. In his laboratory at McGill, the researcher opens his door to the cameras of "Québec scientifique".

Cutting-edge optical laser technique promises to eliminate the need for slides, staining and microscopes

Paul Wiseman and his research team have developed a radically new technique that uses lasers and non-linear optical effects to detect malaria infection in human blood. The new technique promises simpler, faster and far less labour-intensive detection of the malaria parasite in blood samples.

Effects of rural depopulation

When communities are broken apart by migration towards towns and cities, rural life suffers. But now, researchers have revealed that biodiversity can also be affected when humans move away. Aerin Jacob, a biologist at McGill University, and her team discovered that as people leave an area, one dominant habitat comes to take over from the diverse mosaic of human-maintained landscapes.

Debunking myths doesn't zap sci-fi's fun

McGill University's Freaky Fridays program, a series of science lectures followed by film screenings, is here to demystify science, dispel some of its more pervasive myths, and keep us terrified of an approaching scientific apocalypse. Started in 2006, the now-monthly series is organized by Ingrid Birker, McGill's science outreach co-ordinator.

Change in FDA's ethical guidelines for clinical trials troubling

In a commentary published in the Jan. 3 issue of the Lancet, medical research expert Jonathan Kimmelman of McGill University, along with colleagues from the University of Western Ontario and University of Indiana call the FDA's move away from the Declaration of Helsinki as an ethical foundation for international clinical trials "troubling."

Mutant worms

C. elegans, has always been a favourite of scientists. One of its fascinating tricks is that if times are tough, it can wait them out by entering a life-extending state called dauer. Dr Richard Roy, a professor of biology at McGill thinks it could have interesting implications for all sorts of issues in humans, including why we don't lose weight when we diet.

Climate change - unlike the financial meltdown – is a long-haul crisis

In The Gazette, McGill research fellow James D. Ford and Assistant Prof. Lea Berrang-Ford, write (along with U of Guelph's Tristan Pierce): "The climate crisis has not gone away and even as the global economy slows down, emissions of greenhouse gases continue to rise fast. So fast that many scientists have identified the next few years as critical if we are to prevent dangerous climate change."
