Hitting the right notes to play music by ear

The study identified four simple ways music learning technology can aid prospective musicians, including helping people improve recall while listening and replaying notes indefinitely. Researchers found that existing digital learning tools were not being used effectively by students despite their availability.

Clear waters, hidden toxins

Viruses that infect and kill toxic algal blooms can cause the release of high levels of toxin microcystin-LR into water, posing a significant risk to human health and ecosystems. The finding highlights the need for better understanding of these interactions to inform forecasting and mitigation strategies for harmful algal blooms.

High blood pressure? Eat more bananas

Increasing dietary potassium and reducing sodium can effectively regulate blood pressure, according to a new mathematical model developed by the University of Waterloo. The study suggests that a higher ratio of potassium to sodium intake may be more effective for lowering blood pressure than simply reducing sodium intake.

One-third of older Canadians at nutritional risk, study finds

A new study found that one-third of Canadian adults aged 55 or older are nutritionally at risk, potentially leading to increased hospital stays and emergency visits. The SCREEN-8 tool was used to measure an individual's nutrition risk, and those with higher scores had significantly lower odds of reporting healthcare issues.

Warm seawater speeding up melting of ‘Doomsday Glacier,’ scientists warn

Warm seawater is pumping underneath Antarctica's Thwaites Glacier, causing ice to melt intensely and leading to devastating sea level rise. Researchers predict the glacier may retreat into the deeper part of the basin within 10-20 years, accelerating glacier melt and impacting coastal communities worldwide.
