Community researchers discuss the impact of brain injury at BC Consensus Day at the University of Victoria. As many as 600,000 overdose-related brain injuries have occurred in Canada during the toxic drug crisis.

The toxic drug crisis is not only about fatalities. A much larger number of people survive overdoses, and are left with brain injuries. A national strategy to support and treat them is crucial.
The majestic St. Lawrence River, a jewel of economic, historical and environmental importance, reminds us of the need to preserve this essential ecosystem.

The waters of the St. Lawrence are running out of breath and bottom-dwelling organisms are already feeling the effects. Here’s how ecosystems are reacting.
When fish like this netted cod are exposed to mercury, it accumulates in certain organs, including the lenses of their eyes.

Nutrient pollution fouls lakes and bays with algae, killing fish and threatening public health. Progress curbing it has been slow, mainly because of farm pollution.
The Estuary and Gulf of St. Lawrence is one of, if not the largest estuarine system on Earth. It plays an intrinsic role in the history of Canada and is the cradle of Quebec’s economy, and its identity.

Climate change is causing the deep waters in parts of the St. Lawrence River to lose their oxygen, and it’s damaging the health of the ecosystem.

Opioids can cause death by slowing breathing to dangerously low levels, or stopping it altogether. Examining one area of the brain may eventually lead to safer painkillers.
Sponges are ancient marine animals and have already shown robustness against stresses from climate change. New research now shows they can also tolerate low-oxygen conditions.
Diagnosing obstructive sleep apnea usually requires a labour-intensive overnight sleep study. But new technology can tell patients if they have OSA in 30 seconds, while they are wide awake.

Oxygen is vital for life, so much so that cells can sense when there isn’t enough and adapt almost instantly. So how do they do it? The winners of the 2019 Nobel Prize for Physiology figured it out.

Tiny calcified formations inside fishes’ ears can be used to trace a fish’s life history – and potentially, how climate change has affected its growth and development.
How well you’ll cope on a mountain has little to do with how fit you are.
