Brute-force photon counting from a single emitter gets bogged down in noise, like digging a tunnel with a shovel. But introduce a coherent reference beam and let quantum interference kick in — and the picture changes dramatically: the noisier the environment, the faster the verdict. The extended Hon

A new method uses light to shine through thin brain slices and deep learning for automatic analysis. The DenseNet121 neural network identifies structural changes with 88% accuracy, speeding up diagnosis and reducing the risk of error. The technology will aid in early detection of tumors and other pa

Neutrons from fusion turn stable elements into radiopharmaceuticals—without waste or nuclear reactors. A single compact source will replace dozens of outdated facilities and meet global demand for diagnostic and therapeutic isotopes.

Scientists have turned a diamond with a microscopic defect into an ultrasensitive sensor. It measures how quickly the magnetic response of hydrogen nuclei in cells decays. Each cancer line has its own rate — like a fingerprint. The method requires no staining and paves the way for gentle diagnostics

Defects in diamond turn into ultra-sensitive magnetic sensors. By using a noise subtraction method with two sensors (like hearing with two ears), they registered a magnetocardiogram for the first time in a regular room. Compact and requiring no cooling, they promise low-cost contactless diagnostics.
