Light exposure can modulate cognitive function, yet its effects outside of controlled laboratory settings remain insufficiently explored. To examine the relationship between real-world light exposure ...

Detecting gas molecules through light scattering is fundamentally limited by weak signals and environmental noise. To address this, researchers ...

Tracking people’s light exposure in everyday life reveals that brighter, more stable daily light is linked to feeling less sleepy and responding faster on key cognitive tasks, highlighting light as a ...

The thin, flexible, wireless device sits next to a quarter for scale. Device emits complex patterns of light (shown here as an "N") to transmit information directly to the brain. In a new leap for ...

Restoring lost senses or delivering precise brain signals has required invasive hardware and can’t mimic the brain’s natural, distributed activity patterns. This platform shows the brain can learn to ...

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain—bypassing the body's ...

Scientists used light to control how a starfish egg cell jiggles and moves during its earliest stage of development. Their optical system could guide the design of synthetic, light-activated cells for ...
