A fairy-like robot flies by the power of wind and light

The development of stimuli-responsive polymers has brought about a wealth of material-related opportunities for next-generation small-scale, wirelessly controlled soft-bodied robots. For some time now, engineers have known ...


Revolutionizing data access through new software tool: Tiled

Every time scientists study a new material for future batteries or investigate diseases to develop new drugs, they must wade through an ocean of data. Today, a whole ecosystem of scientific tools creates a wild variety of ...


Glowing contact lens could prevent a leading cause of blindness

Hundreds of millions of people suffer from diabetes worldwide, putting them at risk for a creeping blindness, or diabetic retinopathy, that comes with the disease in its more advanced stages. Existing treatments, though effective, ...


Investigating 3-D-printed structures in real time

A team of scientists working at the National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy's (DOE's) Brookhaven National Laboratory has designed an apparatus that can take simultaneous temperature ...

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.
