Stealth technology may not be very stealthy in the future thanks to a new quantum radar system that uses the phenomenon of quantum entanglement to eliminate heavy background noise, thereby defeating stealth anti-radar technologies to detect incoming aircraft and missiles with much greater accuracy.

Black holes can be anywhere from a few times the mass of the Sun up to millions of times that, but some even bigger than that. A new study of data gathered by NASA’s Chandra X-ray telescope has found these so-called “ultramassive” black holes may be larger and more common than we thought.

Construction work has officially begun on a new supertall skyscraper in central Toronto. Designed by high-profile British architecture firm Foster + Partners, the mixed use building will rise to a height of 306 m (1,003 ft), making it Canada's tallest skyscraper once complete.

From all-electric cars like the NIO EP9 to the graphene-laden GTA Spano, free thinkers are currently spoilt for choice in the supercar world. That hasn't deterred Anibal from having a crack at creating a handsome, fast supercar. Meet the Icon, a Canadian supercar with a German heart.

Assembly of a new giant Canadian radio telescope that has no moving parts yet is capable of scanning half the sky in a single day has been completed. The Canadian Hydrogen Intensity Mapping Experiment is composed of four 100-m-long metal troughs covering an area the size of five NHL hockey rinks.

Quantum encryption could make for much less hackable communication networks. But for it to really take off it needs to work out in the real world, among other signals and natural air turbulence. Now, researchers have successfully sent a message with 4D quantum encryption between two rooftops.

When it needs to pump more blood, the heart can grow in response to exercise and pregnancy, but after a heart attack, swelling can lead to further complications. Now scientists have found that a protein called cardiotrophin 1 (CT1) can trick the heart into the good kind of growth and reduce the bad.

Canadian palaeontologists have described one of the most intact fossils ever found, which almost looks like it could wake up any minute. The specimen’s skin and stomach contents have been preserved, giving new clues to its diet and camouflage.

If files on your computer suddenly vanished, you’d be in line for a new one pretty quickly, and yet that’s what our brains do all the time. Forgetting is a frustrating experience, but a new paper suggests that when it comes to human memory, forgetting things may be just as important as remembering.

​While Earth wasn't exactly the best place to set up home during the Archaean era​, life still​ managed to thrive in its oxygen-free ancient oceans. Though much of this period remains a mystery, the still depths of Canada’s Boreal Shield lakes could offer clues to our early origin story.

The Canadian telecommunications regulator has declared broadband access as necessary for the quality of life of all citizens, a claim backed by up to CAD$750 million (US$556 million) in new funding to bring every last Canadian online. ​​​​​

Scientists have unearthed a new bird species from fossils in the Canadian Arctic dating back about 90 million years, making them the oldest records of avian species found so far north and suggesting an intense warming event occurred during the late Cretaceous period.
