Iran's Khamenei is dead — mass state funeral in Tehran, succession still unresolved
Iran held a vast funeral for Supreme Leader Ayatollah Ali Khamenei in Tehran over the weekend, with state media reporting enormous crowds and "vows of revenge." His three sons appeared, but no successor has been named and the presumptive new leader is reportedly staying out of public view — a rare succession vacuum at the top of the Islamic Republic. It caps a brutal stretch since the June war and leaves the post-war ceasefire looking fragile (Reuters, Al Jazeera, Washington Post).
Why it matters to you: succession uncertainty plus renewed Strait of Hormuz saber-rattling is the classic setup for an oil-price spike — watch the pump and the markets this week. Talking point: a leadership transition this opaque in a nuclear-threshold state is the kind of thing that moves the whole board, quietly.

The 2025 ACLS guidelines hit the floor — what actually changes at 3 a.m.
The Hospitalist ran a practical "what's new, what matters" breakdown of implementing the updated ACLS guidelines — the piece is aimed squarely at hospitalists running or supervising codes, not just the code team (The Hospitalist).
Why it matters to you: you're the senior body in the room on a lot of overnight arrests. Worth a 10-minute skim so your muscle memory matches the current algorithm — especially the post-ROSC and medication timing tweaks. Action: flag it for the next night-team huddle.

Cuba's crisis deepens: fuel blockade hits the harvest, health system buckling
Two hard looks at the island this week: the Financial Times reports Cuban farmers are rushing to sell land as a U.S. fuel blockade strands harvests, while CBS News documents a public-health system in crisis under the embargo and shortages. The Economist frames the promised market reforms as potentially radical — if they hold (The Economist).
Why it matters to you: a physician's read on a collapsing health system — medicine shortages, suspended services, clinicians emigrating — is a sobering counterpoint to the reform optimism. Talking point: the reform story and the collapse story are both true at once.
