One of the main ways cells "talk" to each other to coordinate essential biological activities such as muscle contraction, hormone release, neuronal firing, digestion and immune activation is through ...

Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years.

Photopharmacology is an emerging approach that uses light-responsive compounds to control drug activity with high spatial and temporal precision. Traditional therapeutics typically result in unwanted ...

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 ...

Light can be used to activate drugs in specific parts of the body through photopharmacology. This innovative approach involves modifying the chemical structure of a drug by adding a light-activated ...

Vials held upright in a container with a grid of openings are on a lab bench and illuminated by a blue lamp. Many organic-synthesis labs have access to blue lights for photochemical reactions.
