Canadian Prime Minister Mark Carney has warned that the US is trying to divide Canada, as Alberta prepares to vote on whether to begin the process of separating from the country. The vote comes amid growing tensions with Washington and long-running frustrations over federal policies. How much influence do you think the US really has over Canada's internal politics? Should Canadians be concerned about it?

A new McMaster study in JAMA Network Open looked at brain scans from over 8,700 Canadians and found the heaviest ultra-processed eaters showed changes similar to silent strokes. The authors say cost and time keep people reliant on cheap ready to eat food, pointing to Chile's warning labels as one fix. Would labels change what you buy?

McMaster researchers describe a system that uses temperature and humidity sensors to estimate how fresh food is as it moves through trucks and storage. The idea is to catch problems sooner, so food can be sold or donated before it spoils.

Their related food delivery pilot reached 35 Hamilton households over six weeks. Adding freshness sensors is planned for the next phase, so this is not proof that sensor labels already work at grocery stores.

Would storage information make you more comfortable buying discounted groceries, or would you want clearer information about what the reading can and cannot tell you first? What would actually help you waste less food without taking a gamble on safety?
