About "Science & Technology"

The newest Canadian research and technological advances that are changing the way we understand and interact with our environment and each other.

Vents and chimneys on an underwater volcano

Colourful hydrothermal vents and chimneys on the volcanic Vailulu'u seamount in the Samoan islands. The ocean floor was long thought to be flat and featureless, but new technology is revealing — and mapping — its diverse topography. (Photo: Vailulu'u 2005 Exploration, NOAA-OE)

Canadian technology takes ocean mapping to new depths
Researchers and industry leaders now have quicker access to data showing the complexity of the world’s seabed. Part five of Canada’s Ocean Supercluster: a six-part series.

Animal crossing: Reconnecting North America’s most important wildlife corridor
This past summer an ambitious wildlife under/overpass system broke ground in B.C. on a deadly stretch of highway just west of the Alberta border. Here’s how it happened.
Three polar bears cast long shadows as they move across snowy Arctic scenery

Since the start of satellite records in 1979, the number of days per year that sea ice is present has declined in each subpopulation’s region. (Photo: Andreas Preußer, CC BY-ND 3.0)

How has the COVID-19 pandemic affected the transmission of flu?
Public health measures aimed at slowing the spread of COVID-19 have also reduced transmission of flu — but this is not the year to blow off your annual flu shot
Two men scale a steep cliff above a lake

Canadian Space Agency astronaut Joshua Kutryk and NASA Artemis astronaut Matthew Dominick hunt for rocks on a cliff above Kamestastin Lake in Labrador. The lake was created by a meteorite impact, and the area’s geology has many similarities to that of the moon. (Photo: Gordon Osinski)

Why a Labrador crater is the perfect training ground for future moon explorers
Future missions to the moon will focus heavily on geology. Fortunately, Canada offers astronauts the perfect place to hone their skills.
leather sea stars

Two leather sea stars photographed by marine ecologist Chris Harley in Vancouver’s Stanley Park on July 12, 2021, illustrate the impact of the extreme heat wave that hit Western Canada this past summer. The live star on the left was in a shady spot, while the star on the right perished in the direct sun. (Photos: Chris Harley)

“We did this:” Is there a way out of our intertwined climate and biodiversity crises?
As the impacts of global warming become increasingly evident, the connections to biodiversity loss are hard to ignore. Can this fall’s two key international climate conferences point us to a nature-positive future?

What if we could plant trees as quickly as we cut them down?
Experts say global reforestation is one of our best defences against climate change, so a Toronto-based company is developing drones that can get the job done quickly
Soft sunrise colours over Niagara Falls

A natural wonder? Niagara Falls as it appears today has actually been heavily engineered to hide power generation infrastructure behind a tourist-friendly façade. (Photo: Stuart Hendrie/Can Geo Photo Club)
