Canadian science news: 18-24 May 2015

I cover science and innovation for Ontario (excluding Ottawa), liaising with all relevant research institutions and companies. In 2015 I expect to be working on future cities, high-performance computing and innovation in healthcare, as well as continuing prior work on dementia, regenerative medicine and science outreach. In the free time that I have after managing multiple small children, I enjoy home improvement and board/computer gaming. You can follow me on Twitter at @jcpreece
