Security loophole allowing attackers to use WiFi to see through walls
Security loophole allowing attackers to use WiFi to see through walls
A research team based out of the University of Waterloo has developed a drone-powered device that can use WiFi networks to see through walls. The device, nicknamed Wi-Peep, can fly near a building and then use the inhabitants' WiFi network to identify and locate all WiFi-enabled devices inside in a matter of seconds.

The solar ballet of the white trillium
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
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.

Experts unveil toolkit to measure hospitals’ safeguards against disruption
Never before in the history of modern medicine has the world experienced a shutdown of elective surgical systems as was experienced during the COVID-19 pandemic, says Western University researcher Janet Martin. An expert in global access to safe surgery, Martin and a team of experts from around the world have published a study in The Lancet that aims to help to improve resilience of hospitals against future surgical cancellations and backlogs worldwide.

Traffic-related air pollution linked to increased risk of dementia
Traffic-related air pollution linked to increased risk of dementia
Higher exposure to a certain type of traffic-related air pollution called particulate matter may be linked to an increased risk of dementia, according to a meta-analysis by Western researchers published this week in Neurology , the medical journal of the American Academy of Neurology. While at Western, graduate student Dr. Ehasan Abolhasani specifically looked at fine particulate matter which consists of pollutant particles of less than 2.5 microns in diameter suspended in air.

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).

Anxiety disorders had no effect on vaccine hesitancy
Anxiety disorders had no effect on vaccine hesitancy
Individuals who deal with anxiety are not less hesitant to get the COVID-19 vaccine Individuals who deal with anxiety are no less hesitant to get the COVID-19 vaccine compared to those without anxiety, according to new research. The new study led by the University of Waterloo aimed to investigate the relationship between vaccine hesitancy, psychological factors associated with anxiety, and individuals' reasoning for and against getting the COVID-19 vaccine.

Get enough sleep and live longer!
People who follow sleep duration recommendations are likely to live longer, according to a study by researcher Julie Carrier, professor in the Psychology Department, and her colleagues. Are you an adult aged between 18 and 64 who sleeps 7-9 hours a day? Or are you over 65 and sleep 7-8 hours a day? Following these Canadian recommendations on sleep duration could increase your life expectancy.

Penguin feathers may hold an effective anti-icing solution
McGill University research team develops chemical-free solution that could be used to de-ice electrical wires, wind turbines and even airplane wings In 1998, ice build-up on electrical towers and wires caused the ice storm that paralyzed eastern Canada and the northeastern United States, leaving many people in the dark and cold for days and even weeks.

Genomic data can improve pandemic modelling, SFU researchers say
Simon Fraser researchers are advocating for the inclusion of genomic data into forecasting models to better understand the spread of infectious diseases. The researchers say incorporating this data into forecasting models can inform monitoring, coordination and help determine where resources are needed.

Seawater holds -memories- in the form of DNA from fish and invertebrates that have recently passed by. This information, called environmental DNA or eDNA, can be used by scientists to track species across space.

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.

Unlocking the mysteries of tauopathies: a protein that gives hope
A protein called 'numb' acts as a regulator of intracellular tau levels - and could someday be used to treat neurogenerative diseases, an UdeM-IRCM study finds. CONTENU - A mechanism has been found that controls cellular levels of tau, a protein whose abnormal accumulation is at the root of tauopathies, a class of devastating neurodegenerative diseases.

Transparent face masks restore emotional understanding, but not empathy
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.
