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 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.
A new study shows that a time stamp can be put on mercury that accumulates in fish eyes, offering a window into their lifetime exposure.
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.
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.
A doctor and lifelong figure skater explains what was found in Valieva’s drug test, what effects the substances might have and how performance enhancements might benefit a figure skater.
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.
Keeping an eye on your oxygen levels at home can give you early warning your COVID is deteriorating.
If your COVID symptoms worsen suddenly, hospital is the best place for you to be monitored, treated and to recover well.
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.
It’s possible that low oxygen levels in caves produced hallucinations – but that doesn’t explain the majority of prehistoric art.
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.
It may look like a whiskered cocktail sausage, but the naked mole rat’s incredible biology may one day improve countless lives.
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.
You can’t know how altitude will affect you until you’re up there. Here’s why people have different reactions to less atmospheric oxygen.
