‘Ghostly’ neutrinos provide new path to study protons
Scientists are that much closer to understanding protons today after using a novel technique involving a high-energy neutrino beam to precisely measure their size, which could change how these kinds of experiments are done and answer many more questions, say researchers from York University.

That sinking feeling: Are ice roads holding up under January’s unseasonable warmth?
Vital winter ice road infrastructure may be cracking and sinking under the load of an unseasonably warm start to the new year across Europe and North America, a trend York University Associate Professor Sapna Sharma and team has detailed in a recent study.

New, portable device detects glow emitted by plants to measure their health
When plants are healthy, they emit red light that is nearly impossible to see with the naked eye, but with a new instrument developed at York University, it's now possible to measure that light whether in a lab or out in the field.
York University professors create device that could revolutionize assessing plant health

COVID-19 transmission higher in households than in workplaces, schools or community
New research out of York University has found the transmission of COVID-19 is much higher in households than in workplaces, schools or the community as the potential for prolonged contact with infected people is greater in the home.

Webb reveals a galaxy sparkling with the universe’s oldest star clusters
Using the James Webb Space Telescope (JWST), researchers from the CAnadian NIRISS Unbiased Cluster Survey (CANUCS) team, including York University, have identified the most distant globular clusters ever discovered. These dense groups of millions of stars may be relics that contain the first and oldest stars in the universe.
