Four hospitals have completed the final leg of a three-week-long cross-country medical relay. In the first-of-its-kind series of surgeries, doctors exchanged not batons, but kidneys, involving 16 separate procedures.

Young visitors at the Ontario Science Center are being asked to donate their saliva by spitting in collection tubes. In charge of the spitting booth is the Hospital for Sick Children in Toronto.

The unusual specimen collection endeavor is part of the Spit for Science project in Canada, which aims to collect the spit of 10,000 young people between the ages seven to 17. Their saliva and behavioral information would go through DNA analysis for researchers to find out if there is a link between obsessive-compulsive and attention-deficit hyperactivity disorders and a child's genetic make-up.
