Existing neuroscientific models of the visual system suggest that it represents the visual world just as a camera would, encoding the positions of different objects similarly. An animal's surrounding environment, however, ...
The outer layer of the brain, known as the cortex, is made of different types of neurons. Neuroscience studies suggest that these different neuron types have distinct functions, yet for a long time this was difficult to ascertain, ...
The real-time monitoring of intravascular oxygen levels is important to accurately track the cardiopulmonary health of patients after cardiothoracic surgery. Existing methods use intravascular placement of glass fiber-optic ...
Researchers from MIT have developed a 3D-printable tissue adhesive that demonstrates superior tissue adhesion, rapid sealing capabilities across various surgical scenarios and a unique blood-repelling feature. The technology ...
Research led by Peking University, China, has discovered a single type of retinal photoreceptor cell in Drosophila (fruit fly) is involved in both visual perception and circadian photoentrainment by co-releasing histamine ...
Optogenetics are advanced research tools that allow scientists to precisely control the activity of brain cells using light. Over the past few years, optogenetic techniques have become increasingly advanced, leading to exciting ...
In a multi-year research program coordinated by the two directors of .NeuroRestore—Grégoire Courtine, a neuroscience professor at EPFL, and Jocelyne Bloch, a neurosurgeon at Lausanne University Hospital (CHUV)—patients ...

A new treatment for eliminating surface bacteria using blue light and carvacrol, a phenol derived from edible oils, creates a photoxic, bacteria-specific reaction that does not contribute to antibiotic resistance. The technique, ...
A team of researchers affiliated with multiple institutions in Germany has developed a cochlear implant that converts sound waves to light signals instead of electrical signals. In their paper published in the journal Science ...
Electromagnetic radiation (EMR) exposure from the sun and artificial lighting systems represent a health risk, therefore personalized methods for EMR dosimetry can guide people toward lifestyle behaviors that ensure healthy ...
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.
