Peterborough – When the World Health Organization (WHO) issued a warning in 2016 about the connection between drinking very hot beverages (above 65 C) and esophageal cancer, researchers at Trent University had an unlikely solution: soybeans.
Within months, they developed a travel mug that uses a unique soy-based material inside its walls to cool beverages to safe temperatures within minutes, and maintain the temperature in a perfect range for several hours.
Dr. Suresh Narine, professor in Physics, Astronomy and Chemistry who also heads up the Trent Centre for Biomaterials Research (TCBR), has been experimenting with energy storage properties in lipids. He says the research team developed the material in response to a challenge: how to use biomaterials to store energy, and control how that stored energy gets released.
“We figured out how to design materials that melts or crystallizes at specific temperatures,” says Narine. “It stores the heat when it melts, and when the material crystallizes, it gives that heat back.” Continue reading →
Guelph – When Animesh Dutta ponders the problems of the world, he lands on energy security, food security and climate change. The University of Guelph researcher’s latest project holds promise for addressing all three.
As professor and director of the Bio-Renewable Innovation Lab in the School of Engineering, Dutta focuses on taking waste from farms or food processors and finding the best solution to convert it into renewable energy that will maximize the economics.
When he started working on bioenergy, Dutta saw the benefits of creating a renewable source of energy that didn’t interfere with food production.
“The economics don’t seem to be there for using feedstock for bioenergy,” he says. “You have to purchase the raw product and farmers want a price for their biomass crop that is higher than the value of the bioenergy it makes.” Continue reading →
Vineland, Ontario – When Dr. Helen K. Fisher retired as viticulture research scientist at Vineland Research and Innovation Centre (Vineland), there were a few loose ends to tie up.
Namely, what to do with her research on advanced wine grape selections for cold climate wine growing regions.
“Breeding work for wine grapes is a very slow process,” says Fisher. “Not only are you trying to find a plant that fits a climate, but it also needs to fit into a wine profile wineries are looking for.” Continue reading →
Guelph – Ontario shrimp farmers could soon be going green – with algae. New research is using algae to naturally clean recirculating saltwater on shrimp farms. Still in the early development stages, the new, highly efficient process of removing nutrients and carbon dioxide from recirculating saltwater is being tested at the University of Guelph.
“It’s not a new idea,” admits Andreas Heyland, lead project researcher and integrative biology professor at the University of Guelph. “But we’ve been able to select highly efficient algae strains, which can be grown on the recirculating water.”
In-land shrimp farming has grown in Ontario in recent years with the demand for local shrimp in closer proximity to the marketplace. As a result, farmers are looking for new ways to manage nutrient build-up in the production system; conventional methods don’t produce much revenue and saltwater can’t be easily disposed in the environment.

Guelph – It’s an unremarkable building from the outside, tucked away on a side street on the University of Guelph campus. What’s inside, though, is most remarkable – and may well be lighting the way for future human life in space, as well as better life here on earth.
Not only are researchers in the Controlled Environment Systems Research Facility working on how to best grow food away from Earth, they’re also experimenting with using light to improve the production of medical marijuana and cancer-fighting tobacco plants, helping nurseries reduce water and fertilizer use on their trees and shrubs, and finding low cost solutions to growing more compact bedding plants.
PhD candidate Dave Hawley is using basil and strawberry plants in experiments designed to find the best LED light combination for use in small, low atmosphere growth chambers that will not only simulate but actually improve upon real sunlight – and resulting in better flavour and ultimately helping feed people on long space journeys.
