Aggression in Childhood: Rooted in Genetics, Influenced by the Environment

Over the past few months, many local cases of assault and harassment have come to light and been widely discussed in the news, both here and in the U.S. and Europe. Why do people have these types of aggressive impulses? To look for an answer, Stéphane Paquin, a PhD candidate in sociology at Université de Montréal working under… Read More »

Cystic fibrosis: discovery of a key molecule for improving treatments

Researchers at the University of Montreal Hospital Research Centre (CRCHUM) have identified a promising solution to improving treatments offered to patients with cystic fibrosis. This advancement, published in Frontiers in Cellular and Infection Microbiology, could lead to the development of new personalized therapies in the near future. “Adding molecules called quorum-sensing inhibitors to current drugs reduces bacterial production of certain harmful… Read More »

Cellular seismology: Putting vibrations on the map

Cells quake. In somewhat the same way that seismologists use the vibrations of planet Earth to characterize its deep structure, scientists have discovered a way to use vibrations within cells to identify their mechanical properties. Thus was born the field of cell seismology. “We developed a unique technique to map, on a scale of milliseconds, the elasticity of… Read More »

Re-programming innate immune cells to fight tuberculosis

Tuberculosis (TB), an infectious disease which attacks the lungs, claims a life every 20 seconds and 1.5 million lives worldwide every year. A cure has eluded scientists for more than a century but, now, a Montreal team of researchers may have discovered a new weapon to combat this global killer. The team is re-programing – or ‘training’ –… Read More »

Nature article turns theory of stellar evolution upside-down

This week, Nature published an article that could challenge the theory of stellar evolution. “I think that, over the coming months, stellar astrophysicists will have to redo their calculations,” said Gilles Fontaine, a physics professor at Université de Montréal and one of the authors of the article, titled “A large oxygen-dominated core from the seismic cartography of a… Read More »

Behavioural problems and concussion in preschoolers

Concussions are a major public-health problem due to their high prevalence in teens and athletes who take part in contact sports. The prevalence is even higher in preschool children because they have a more limited understanding of danger and are therefore more prone to injury. A study conducted by researchers at CHU Sainte-Justine, affiliated with Université de Montréal,… Read More »

Solving the problem of surgical stainless steel

Stainless steel is widely used in surgical medicine: for medical devices such coronary stents, hip-implant stems and spinal-disc replacements, and for a variety of surgical tools such as scalpels and forceps, as well as operating tables. As a material, however, stainless steel isn’t without its flaws. Over time, steel implants can cause allergic and toxic reactions and be… Read More »
