An Alberta mother of the last Canadian soldier killed in Afghanistan has been chosen as this year's Silver Cross Mother. Candy Greff will lay a wreath at the National War Memorial in Ottawa on Remembrance Day, placing it on behalf of all mothers who have lost children to the service of Canada. Her son, Master Corporal Byron Greff, was killed in a suicide bombing in October of 2011 becoming the 158th Canadian soldier to die in the country and the last before Canada's mission there ended in 2014.

We reached Dr. Patricia Lakin Thomas, professor of biology at York University, whose research includes our circadian rhythms and internal clocks.
