Scientists are mobilizing from the ground up and the top down in our fight against COVID-19

Canada’s Chief Science Advisor says our bottleneck in our testing is due to not enough personnel and test ingredients, but that help is on the way.

COVID 19: Can we control the pandemic and move from 'flattening the curve' to 'riding the wave'?

Epidemiologists at the University of Toronto are working on modelling ways we might manage the COVID-19 pandemic after we've "flattened the curve," so we can return to some semblance of a normal life.

Salads in space: NASA has learned to grow lettuce on the space station

Lettuce grown on the International Space Station is just as nutritious as the stuff grown on Earth.

How Pablo Escobar's escaped hippos are helping to restore an ancient ecosystem

Hippos are an example of how so-called invasive species shape their habitats in a similar way to long-extinct megafauna.

As entertainment shuts down, take in the spectacle nature has to offer

Bob McDonald's science blog: Immersing yourself in nature can have positive effects on your physical and mental health.

How aging increases vulnerability to COVID-19 and how pollution can make it worse

Your body's ability to fight off viruses naturally declines as you get older, becoming more weak and less targeted, and pollution exposure makes it even worse.

COVID-19 has led to huge emissions reductions — can we learn from this?

A global pandemic is not how we'd choose to reduce emissions, but scientists are studying how COVID-19 is affecting climate change, and how climate change could affect COVID-19.

Japanese space scientists shot an asteroid to learn about its past

The tiny, rocky asteroid Ryugu, in orbit between Earth and Mars, gives up some of its secrets.

'Wonderchicken' walked among the dinosaurs just before the mass extinction

Thought to be the oldest modern bird fossil, the 66.7 million-year-old "Wonderchicken" may help scientists understand more about the rise of birds and why they survived the mass extinction.

Seismic technology to probe the Earth adapted to probe the brain

Bob McDonald's science blog: Scientists have developed a portable brain scanner that could open up new research opportunities.

COVID-19: Why reacting early and aggressively is the key to avoiding crisis

'If we allow this to get bad, it gets bad fast, and it gets horrible fast. And that's why we have to be proactive.'

How the Greenland Ice Sheet is melting from the bottom up

The shape of the sea floor is flushing warm water underneath the glacier, so it is melting from above and below.

Squat, don't sit: The way we are sedentary could make a big difference to our health

Scientists studied hunter-gatherers to measure the posture muscle activity to get a glimpse into our evolutionary past

SmartICE: Supporting Inuit knowledge of the landscape with technology

'It's like you have a hand again': A major breakthrough in robotic limb technology

Researchers devised a novel way of grafting tiny bits of muscle to amputated nerves so as to provide a way to control a robotic limb.

Is damming the entire North Sea a realistic way to defend against sea level rise?

It might be possible to build two giant dams to isolate much of Europe from the rising Atlantic, and it might be the only defence if we don't act fast to control climate change
