Ground Truths

Life science and medicine, from someone who still sees patients.

Substack Science Weekly Updated Aug 2026

About

Ground Truths is cardiologist and researcher Eric Topol's newsletter on life science and medicine, written by someone who still sees patients alongside his research and writing. That clinical grounding shapes how he covers new studies and medical technology, less abstractly than most.

Genomics, AI in medicine, longevity science, all get dug into with a working physician's read on what actually matters for patients versus what's just a promising headline. For readers who want serious medical science without the hype that surrounds so much health reporting.
