How it works
How the weekly selection works
The goal is to make each item readable now and still useful later, when results, follow-up, or regulatory updates arrive.
- A short weekly selection instead of a high-volume news feed
- Longer articles when a study, trial, or regulatory event needs context
- Plain language around trial stage, approval status, and what has actually been reported
- Attention to product, route, endpoint, durability, safety, and clinical usefulness
