The solar ballet of the white trillium
The flowers of the white trillium follow the sun, which increases their fecundity, according to a research team in biological sciences at UdeM. Have you ever noticed, during your walks in the forest, that the flowers of the white trilliums all point in the same direction? In fact, the flowers are pointing south, towards the sun, and this is far from being a coincidence.

An ultra-light photo collar to study lemmings
Developed by a team at Laval University, this collar, which weighs less than a dime, will allow the study of lemming activity patterns during the summer Although lemmings play a central role in the Arctic terrestrial food chain, their living habits are still largely unknown. One reason is that these small rodents spend most of the year in tunnels in the ground or snow, out of sight of researchers.

Subatomic MRI could lead to new drug therapies
A new imaging technique using quantum science may lead to novel drug therapies and treatment options, a recent study has found. Researchers at the University of Waterloo and supported by Transformative Quantum Technologies have demonstrated the feasibility of Nuclear Magnetic Resonance diffraction (NMRd) to investigate the lattice structure of crystalline solids on an atomic scale, a feat that had only been possible for larger-scale imaging applications like Magnetic Resonance Imaging (MRI).

Systemic gender barriers mean going it alone may not be the answer for all new women entrepreneurs in Canada
Gender-equal ownership can help women overcome the systemic barriers their new businesses face A new study reveals that inexperienced entrepreneurial women in Canada still see more success when partnering with experienced men than when partnering with experienced women or going it alone. That is the key finding from research coming out of the University of Waterloo and Statistics Canada based on an analysis of 183,358 unique Canadian business ventures from 2006 to 2017 and the impact of co-ownership by women and men.

Activity ’snacks’ following meals may help maintain muscle mass: Study
Interrupting prolonged sitting with periodic activity "snacks" may help maintain muscle mass and quality, according to a new study by researchers at the University of Toronto. Daniel Moore , an associate professor of muscle physiology at the Faculty of Kinesiology & Physical Eduction (KPE) who led the study, found that short bouts of activity, such as two minutes of walking or body weight sit-to-stand squats, allow the body to use more amino acids from meals to build muscle proteins.

Transparent face masks restore emotional understanding, but not empathy
Mask-wearing has become the norm for many since the beginning of the COVID-19 pandemic. Despite their effectiveness in preventing the spread of viruses, opaque masks impair our ability to understand and convey emotions, a group of McGill researchers has found. McGill researchers Jelena Ristic , Full Professor in the Department of Psychology, and Sarah McCrackin , Postdoctoral Fellow in the Department of Psychology, discuss whether transparent masks reduce the negative impacts on social communication.

Researchers shrink brain tumours with gold nanoparticles, develop ’mini brains’ to study psychiatric disorders
Researchers at the University of Toronto are inching closer to realizing a life-saving brain cancer treatment by using gold nanoparticles to make radiation therapy more effective and less toxic for patients. In their battle against glioblastoma multiforme (GBM), a rare, fast-growing cancer that begins in the brain, the multidisciplinary team has discovered that the nanoparticles can keep radiation tightly focused on the tumour, shrinking its size and preventing damage elsewhere in the body.
