Four engineering students and researchers at McMaster University (Ontario) won the James Dyson Award for creating a device that can identify cancerous lesions on the skin.
The device, known as sKan, is connected to a computer program and can quickly sense the presence of melanoma thanks to thermistors that measure skin temperature in a specific area.
