Diamond sensor picks up the heart's magnetic signals ⚡ экспресс
Original: "Human Cardiac Measurements with Diamond Magnetometers"
A tiny diamond sensor, working like a pair of microscopic ears, recorded the heart's magnetic field for the first time without a specialized shielding chamber.

A tiny diamond sensor, no thicker than a grain of sand, captured the magnetic heartbeat—even without bulky noise protection. How? It works like two ears that cancel out noise, and promises to one day replace bulky magnetometers with a compact quantum device.
🎯 The heart's magnetic pulse was first captured in 1963—the setup was the size of a car and required expensive magnetic shielding.
🎬 The medical tricorder from Star Trek is closer than it seems: a compact diamond sensor reads magnetic rhythms without contact.
