�鶹ֱ��app

Through fluorescent cells projected onto walls to solar-powered vehicles, the University of Toronto community showed thousands of people the wonders of science on Saturday.

Science Rendezvous brought �鶹ֱ��app research from the lab to the streets to inspire the next generation of scientists. The science festival began in 2008 as an initiative of the University of Toronto, Ryerson University, York University and the University of Ontario Institute of Technology. It has since become the largest science festival in the country, organizers say.

�鶹ֱ��app News captured some of the action over the weekend.

Sylva Donaldson, project manager of CAGEF, says she hoped visitors learned that not all bacteria are bad. “There are a lot of good bacteria in us, on us and in the environment that actually fight off the bad ones.” (photo by Geoffrey Vendeville)
