Pathological lying in teens is associated with executive function deficits, study indicates

Teenagers who are pathological liars also tend to struggle with executive function deficits, such as poor memory or impulse control, researchers have found.

Night owl or early bird? Study finds sleep categories aren’t that simple

The familiar labels “night owl” and “early bird,” long used in sleep research, don’t fully capture the diversity of human internal clocks, a new study has found.

The McGill University-led study published in Nature Communications found the two sleep-wake patterns, called chronotypes, contain a total of five distinct biological subtypes, each associated with different patterns of behaviour and health.

Hippocampus does more than store memories: it predicts rewards, study finds

A preclinical study published in Nature has found evidence that the hippocampus, the brain region that stores memory, also reorganizes memories to anticipate future outcomes.

A rich social environment is associated with better cognitive health outcomes for older adults, study finds

Research by an interdisciplinary team from McGill University and Université Laval provides new insights into the links between social factors and cognitive health among aging adults.

In polar regions, microbes are influencing climate change as frozen ecosystems thaw, McGill review finds 

Microbes across Earth’s coldest regions are becoming more active as glaciers, permafrost and sea ice thaw, accelerating carbon release and potentially amplifying climate change, according to a new international review from McGill University. 

McGill researchers create shapeshifting materials that could power the next generation of soft robots

McGill University engineers have developed new ultra-thin materials that can be programmed to move, fold and reshape themselves, much like animated origami. They open the door to softer, safer and more adaptable robots that could be used in medical tools that gently move inside the body, wearable devices that change shape on the skin or smart packaging that reacts to its environment.

McGill Nursing students providing care for homeless and at-risk Montrealers

According to a 2015 census, there are just over 3,000 homeless people living in Montreal. This number does not account for those who are dealing with hidden homelessness, such as temporarily living with friends or family or other short-term accommodation.

In addition to the many challenges and stresses of homelessness—such as meeting immediate survival needs for food, water, clothing and shelter from the elements—taking care of health needs might seem insurmountable.
