Activated by quarter-second-long light pulses, the molecular machines allowed scientists to control calcium signaling in a cardiac myocyte cell culture, causing the inactive cells to fire. "The ...

Photopharmacology combines light and drug action, offering reversible control over biological pathways, transforming ...

More than 100,000 people in the US died after overdosing on opioid drugs last year, according to the National Center for Health Statistics. Naloxone, a potent opioid antagonist, swiftly reverses ...

A team has re-engineered immune cells with a light-activated switch that modulates protein function and cellular behavior. When exposed to blue light, the cells change shape, infiltrating solid tumors ...

We’ve all been there: A tight deadline, an overnighter, and the next day we’re navigating life like zombies. For fighter pilots, the last step isn’t an option. During active duty, these pilots need to ...

Scientists can now use light to activate protein functions both inside and outside of living cells. The new method, called light-activated SpyLigation, can turn on proteins that are normally off to ...

Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the tip of a syringe—and be noninvasively injected into the body. Although it can work with hearts of all ...

Rendering a drug effective or ineffective in a flash at the appropriate location—this is the focus of research in photopharmacology. The goal is to develop drugs that can be switched on and off with ...

The Light-Activated BioID technique invented by biomedical engineers at UC Davis could enable studies of how proteins interact with each other inside cells. Biomedical engineers at UC Davis have come ...
