Mount Sinai researchers show reactivating the Cyclin A2 gene can make adult heart cells divide again, potentially enabling hearts to repair themselves after attacks. This is a concrete molecular path to avoid transplants.

Gene therapy lets hearts heal themselves
Heart regeneration is suddenly on the table, and a pilot study shows ultrasound can sneak drugs past the blood-brain barrier in kids. Meanwhile, the week's thread on AI in health gets a sobering reality check from Africa, and medical students are gaming the publication system with big data.
Regeneration and delivery
Two studies today point at fundamentally new ways to repair the body, one by waking up a sleeping gene, the other by opening a barrier that's kept therapies out of the brain.
A pilot study used ultrasound-created microbubbles to temporarily open the blood-brain barrier in children, letting anti-cancer drugs reach brain stem and spinal cord tumors. It's a delivery breakthrough for previously untreatable childhood cancers.
AI health reality check
The gap between AI hype and on-the-ground health needs is widening, and a new report from PATH puts numbers on it.
PATH's chief AI officer points out that Africa carries 25% of the global disease burden with 3% of the health workforce, yet health AI funding is a rounding error compared to Silicon Valley. The piece argues that scaling AI in health needs guardrails, not just capital.
Science integrity
A popular research tool is making it too easy to publish bad science, and the consequences are starting to get attention.

Science.org reports that medical students are using TriNetX, a platform with 300 million patient records, to churn out low-quality studies. The ease of use bypasses rigorous methods, raising concerns about junk science entering the literature.
