Explainer: How the human body first fights off pathogens

We’ve all endured infections. Here’s how it works when our bodies are attacked by viruses, bacteria or parasites, and our innate immune system becomes the first line of defence.
Wildfires may grow more frequent and intense in North America amid climate change, like the Fort McMurray blazes in 2016, which were among the worst in Canadian history. (THE CANADIAN PRESS/Jonathan Hayward)

How wildfires could radically change forests — and your life

Wildfires amid climate change may spark a radical shift in forest habitats and wildlife. They aren’t just a destructive force of man and nature. They’re a key factor in forest ecosystem renewal.
