If I were to offer you the choice between a bucket of deep-fried chicken or a slice of organic roast chicken, you would be pretty clear on what would be the healthy option. Omega-3s, organically grown, bioflavonoids, antioxidants… we understand how important food is to our health.
A new smart window offers more than just a nice view —it also controls the transmittance of sunlight, heats the interiors of buildings by converting solar radiation into heat, and virtually eliminates E. coli bacteria living on the glass. In the future, such sterile smart windows may be used in airplanes, hospitals, public transportation, and other areas.
Shining light on a new material is all it takes to make its surface toxic to germs. If used on the outside of instruments, on countertops and more, the technology might one day help hospitals limit the spread of infections, including ones that no longer respond to drugs.
Reigniting the debate over exposure to the ‘blue light’ emitted by outdoor LED screens and heightened risk of cancer, an international team of researchers have concluded that there is a ‘strong link’ between the two.
Researchers have designed a light-harvesting funnel that absorbs sunlight from any direction and concentrates it onto smaller areas, such as high-performance solar cells. By stacking multiple funnels, each tuned to a different wavelength of light, the researchers expect that it could be possible to convert the entire solar spectrum into electricity with high efficiency.
Continuous low doses of far ultraviolet C (far-UVC) light can kill airborne flu viruses without harming human tissues, according to a new study at the Center for Radiological Research at Columbia University Irving Medical Center (CUIMC).
Spending too much time in dimly lit rooms and offices may actually change the brain's structure and hurt one's ability to remember and learn, indicates groundbreaking research by Michigan State University neuroscientists.
When Thomas Edison patented the first commercially successfully light bulb in 1879, it’s certain that humanity took a huge step forward. No longer would people be restrained from activity or endeavor by the rising and falling of the sun; the era of artificial light had begun.
