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.

Lithium study yields insights in the fight against HIV

Lithium, a widely used treatment for bipolar disorder and other mood disorders, has shown early promise in suppressing HIV, McGill University researchers report.

A new study published in iScience found lithium can prevent infected cells from reactivating, and that it does so through an unexpected biological mechanism.

The findings point toward future treatments designed to mimic lithium’s beneficial effects while avoiding its broader impacts on the body.

McGill study identifies most effective methods for early detection of tench, an invasive freshwater fish

As tench continue to spread through the St. Lawrence River, a study from McGill University provides fisheries managers with guidance on how to detect the invasive species, an essential first step in preventing it from reaching new waters. The findings can inform efforts to contain and manage existing populations, helping agencies determine how and where to carry out removal or control activities.

McGill researchers identify a range of unexpected chemical contaminants in human milk

An interdisciplinary team including researchers at McGill University has found a range of unexpected chemical contaminants in human milk samples from Canada and South Africa. The chemicals include traces of pesticides, antimicrobials and additives used in plastics and personal-care products. The findings were published across five papers.

Freshwater browning threatens growth and populations of economically important fish, McGill researchers say

Freshwater browning is stunting fish growth of some species, shrinking populations of others and changing the composition of fish communities, McGill-led research suggests. “Browning” refers to freshwater bodies turning tea-coloured, a phenomenon driven by higher levels of dissolved organic matter and/or higher levels of iron in the water. Causes include changes in land use and climate, and reduced acid precipitation.

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.
