At the University of California Santa Cruz, biomolecular engineer Andy Yeh has developed a luminescent biosensor that detects cortisol—the body’s primary stress hormone—with unprecedented sensitivity and dynamic range. Cortisol regulates blood pressure, metabolism, and immune response, and imbalances are linked […]

Researchers at Chiba University have developed a microfluidic device that uses nanoimprinted microcone arrays to detect circulating tumor cells (CTCs) in blood with high sensitivity and efficiency. CTCs are cancer cells that break away from primary tumors and travel through

In a major step toward equitable pandemic preparedness, researchers from Italy, India, South Africa, and Slovenia have developed a diagnostic tool called RT-LAMP (reverse transcription loop-mediated isothermal amplification) that delivers COVID-19 results in under an hour using saliva samples—without the

At-home diagnostic tests surged during the COVID-19 pandemic, but their convenience often came at the cost of sensitivity. Now, engineers at UC Berkeley have developed a low-cost biosensing platform that could dramatically improve the accuracy of rapid at-home tests—not just
Cancer treatment has long been a balancing act—target the tumor without harming healthy tissue, deliver drugs precisely, and somehow rally the immune system to keep the disease from coming back. Most therapies manage one or two of these goals, but

For decades, blood pressure monitoring has relied on a 19th-century invention: the inflatable cuff. Whether at the doctor’s office or at home, the process is the same—wrap, squeeze, release, repeat. But while the cuff has become a clinical staple, it’s

If there’s one part of the human body that remains stubbornly elusive despite decades of medical imaging, it’s the gut. We can scan brains, stent arteries, and perform laser eye surgery in high-definition, but when it comes to figuring out

For millions of patients managing chronic conditions like kidney disease, heart failure, or neurological disorders, monitoring blood sodium levels is a routine but invasive necessity. Blood draws, while effective, are uncomfortable, time-consuming, and often impractical for continuous tracking. But a

Northwestern University researchers have unveiled a soft, skin-adhering sleep monitor that could redefine how we detect and manage sleep disorders. Unlike traditional wrist or finger devices, this wireless patch is worn at the base of the neck, allowing for more
