Diamond quantum sensor could reveal elusive altermagnets‎

For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but are increasingly prized for their technological potential. A third category discovered within the last decade may combine the best qualities of both. Dubbed altermagnets, they could someday help create faster, more energy-efficient electronics.

Predator-triggered orange tails may help tadpoles survive by redirecting deadly bites‎

Bright colors in animals are beautiful but often considered risky because they are more obvious to predators. However, conspicuous colors can also serve defensively, signaling toxicity or even luring predators away from more vulnerable body parts.

Plants hit the brakes on immunity to survive viral infections‎

When viruses invade a plant, you might expect an all-out immune war. But new research published in Science shows that, much like in humans, too strong an immune response can actually do more harm than good.

Are taxpayers being gaslighted by street lamp charm?‎

Gas streetlights might look quaint, but researchers at the University of Cincinnati say they are costly, wasteful and release toxic pollutants into the air. In two studies examining their use in Boston, Massachusetts, and Cincinnati, UC researchers found that each lamp releases many times the amount of methane and carbon monoxide of other appliances such as gas stoves and water heaters.

Freeze-dried reagents and hand-powered hardware bring biomanufacturing to remote labs‎

Researchers at the University of Toronto's Leslie Dan Faculty of Pharmacy, working with collaborators around the world, have demonstrated the effectiveness of a suite of low-cost, portable biotechnology tools designed to improve access to laboratory research and diagnostics in resource-limited settings.

Designing catalysts during synthesis could speed cleaner fuels and greener industry‎

The synthesis of materials can serve as a tool for developing smart, adaptive electrocatalysts. This rapidly evolving field of research involves in-situ analytics, data-driven discoveries and autonomous robotics. These new approaches could accelerate the discovery of long-lasting and efficient catalysts for future energy conversion and the decarbonization of the chemical industry.

Vast botanical data help solve Darwin's puzzle of why some exotic plants become pests‎

There's a conundrum that has perplexed biologists since Charles Darwin himself. Why do some exotic species take off as invasive pests while others don't?

IceCube detects break in cosmic neutrino spectrum, ruling out simple power-law model‎

A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.

Citizens as political actors, not individual consumers: New study calls for tighter advertising regulations‎

Commercial marketing oriented toward sustainability is not compatible with degrowth, even when it promotes consuming less. That is the conclusion of a study by ICTA-UAB and the London School of Economics and Political Science.

Antihydrogen mirrors hydrogen in upgraded spectrum test, narrowing cosmic mystery‎

University of Calgary researchers are a part of a group who just got one step closer to solving a mystery of the universe. Dr. Timothy Friesen, Ph.D., an associate professor of Physics and Astronomy in the Faculty of Science, and his team led a new measurement comparing the spectrum of hydrogen to its antimatter counterpart—antihydrogen.
