Premiers Split on Using Potash as a Trade Weapon — What It Means for Your Grocery Bill

  Published August 31, 2026 Canada's premiers can't agree on how far to take the trade war with the United States — and this week, the fight is over a grey mineral mined almost 2,000 kilometres from Ottawa: potash. The disagreement matters well beyond provincial politics. Potash is the "P" and "K" of fertilizer economics — a key ingredient in the blends that grow the wheat, canola, and corn that eventually show up as bread, canola oil, and everything fed to livestock. Canada supplies about 85% of the potash the U.S. uses, which is exactly why some premiers see it as leverage — and why others are warning that pulling that lever could backfire on the very provinces pushing for it.

Alzheimer’s vaccines get a boost from new drug approval

 

After decades of disappointment and controversy, the field of Alzheimer’s disease research has finally seen a breakthrough with the approval of the first drug that targets the underlying pathology of the condition. 

Aducanumab, a monoclonal antibody that clears amyloid plaques from the brain, was granted accelerated approval by the US Food and Drug Administration in June 2021, despite mixed results from clinical trials and objections from some experts. 

The drug’s approval has rekindled interest in other therapeutic approaches that aim to prevent or slow down the progression of Alzheimer’s, such as vaccines that stimulate the immune system to attack amyloid or tau, another protein that accumulates in the brains of people with the disease. 

Several vaccine candidates are currently in various stages of development and testing, and some researchers are optimistic that they could offer a more effective and convenient way to treat Alzheimer’s than infusions of antibodies.
