Ontario’s proposed nuclear waste repository must obtain consent from all affected First Nations

The Nuclear Waste Management Organization has proposed building a nuclear waste repository at a site in northern Ontario. But nearby First Nations say they weren’t consulted.
Jewelweed is found throughout eastern parts of North America. By studying jewelweed, researchers can understand how environmental changes affect plants over time. (Liz West)

How plant populations keep a genetic memory of the past

Genetic signatures help uncover the echoes of the past events in the histories of jewelweed populations, and understand their genetic implications for conservation.

Tracking wildlife using DNA: A scientific breakthrough made with an Indigenous community

Joint research conducted by INRS and the Abitibiwinni First Nation shows how traces of DNA in the snow make it possible to track wildlife without disturbing it.
Hundreds of millions of tonnes of plastic are produced globally every year. New research shows how that waste can be turned into something useful. (Unsplash/Nick Fewings)

How we turned plastic waste into vinegar: A sunlight‑powered breakthrough

Instead of treating plastic purely as waste, new research shows that it can be transformed into something useful — acetic acid, a key component of vinegar and an important industrial chemical.

‘Life is a Miracle,’ but learning from disasters isn’t: Lessons from Japan’s 2011 earthquake and tsunami

Memorials, monuments, preserved school buildings and found objects form part of a memory culture that keeps conversations about risk reduction going.

What pet cats can tell us about human cancer

A new study isolated DNA from the tumours of 500 cats across 13 different tumour types and mapped the sequence of 1,000 genes often found mutated in human cancers.

Budget cuts at Environment and Climate Change Canada threaten Arctic science

For decades, ECCC research scientists have been integral to the work of the Arctic Monitoring and Assessment Programme.
Japanese macaques or snow monkeys, Macaca fuscata to scientists, are a highly social and intelligent species. In wild and free-ranging groups, mothers do not abandon infants. (Brogan M. Stewart)

Wild macaques don’t abandon babies. So why did Punch’s mother?

Japanese macaques are smart social animals. We expect that Punch will be able to learn how to find a place in his monkey group.
The setting sun shines on the snow-covered top of Rainbow Mountain, in Whistler, B.C., in November 2022. Snow cover is becoming more intermittent, particularly during early winter and spring transitions. THE CANADIAN PRESS/Darryl Dyck

Warming winters are reshaping Canada’s snowpack

Climate change is altering not only how much snow falls, but where snowpack persists and how long it lasts.

Why the U.S. is unlikely to curtail China’s critical minerals dominance

China accounts for more than 80 per cent of global battery production. It’s highly unlikely the U.S. can reduce China’s role in the production and processing of critical minerals.

Strong opinions matter: Why some birds refuse to follow the flock

Researchers observed male zebra finches to see if they would follow the flock when building a nest, or stick to their own preferences. It may help us think about conformity in our own species, too.

Vancouver built up fast — but now its older towers face an earthquake reckoning

Modern engineering practices explicitly design concrete to be more resilient to earthquakes, but older buildings predate such practices. That makes them especially vulnerable.
