BMW puts traffic light recognition to the test

The BMW Group is investing in the future of self-driving vehicles. Getting people to adopt self-driving cars will require lots of attention to how these cars can behave safely not just on highways but in urban settings.

Trulifi leveraging light waves for send-receive of office data

Some companies need your time when they explain properly what their technology is all about and in turn brochures, white papers and video talks are in order. Signify is lucky. Two words wrap it up for them. Light connects.

Researchers see around corners to detect object shapes

Computer vision researchers have demonstrated they can use special light sources and sensors to see around corners or through gauzy filters, enabling them to reconstruct the shapes of unseen objects.

Laser technology helps researchers scrutinize cancer cells

Devising the best treatment for a patient with cancer requires doctors to know something about the traits of the cancer from which the patient is suffering. But one of the greatest difficulties in treating cancer is that ...

'Particle robot' works as a cluster of simple units

Taking a cue from biological cells, researchers from MIT, Columbia University, and elsewhere have developed computationally simple robots that connect in large groups to move around, transport objects, and complete other ...

Powering devices—with a desk lamp?

Batteries power most of our devices, and even some cars. But researchers now report in ACS Applied Materials & Interfaces a step toward running electronic devices in homes and offices on the light coming from lamps scattered ...

Light

Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm.) In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.

Three primary properties of light are:

Light, which exists in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.
