In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

EPFL researchers have developed a light-based method that can produce proteins that switch states, respond to signals, and even compute, using light and the cell cycle.

They claim to fix fine lines, blemishes and redness – but which stand up to scrutiny? We asked dermatologists and put them to the test to find out The best anti-ageing creams, serums and treatments ...

A research team led by Sahand Jamal Rahi at EPFL’s Laboratory of the Physics of Biological Systems has introduced a new ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

Because it had to be done.

Plant responses to light are multiple. Light is an energy source, converted to sugars by photosynthesis. It is also a signal sensed by specific photoreceptors for red, blue and UV-B radiation. Absence ...

New for Light + Building 2026, ADI will introduce a DALI power supply and gateway showcase. The gateway plays a critical role in KNX projects, enabling every KNX lighting product to communicate ...
