Study suggests protein made in the liver is a key factor in men’s bone health

New research suggests the liver plays a previously unrecognized role in bone health, but only in males.

A McGill University-led study published in Matrix Biology found that a protein made in the liver helps regulate bone growth in male mice, but not in females. The findings may help explain why men with liver disease are more likely to experience bone loss.

McGill researchers develop quick test that stands to curb antimicrobial resistance

McGill researchers have developed a diagnostic system capable of identifying bacteria –and determining which antibiotics can stop them – in just 36 minutes, a major advance in the global effort to curb antimicrobial resistance (AMR). Current clinical testing methods typically take 48 to 72 hours, leaving physicians without timely guidance.

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.

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.
