Astronauts Steven Smith and John Grunsfeld, appear as small figures in this wide-angle photograph from December 1999, taken ...

Night-vision goggles rely on the fact that living things, and many machines, produce heat at wavelengths far too long for the ...

Researchers have improved upon techniques that use thin films to compress infrared light, demonstrating three advantages that ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

Researchers demonstrated that specific electromagnetic wave frequencies can disrupt the SARS-CoV-2 Spike protein structure in virus-like particles, leading to reduced infectivity in cell models. This ...

The human eye perceives electromagnetic radiation (i.e. light) as different colors, depending on the length of the wave. Blue light has the shortest wavelength. Exposure to blue light in the ...

“A prism produces a ‘rainbow’ by dispersion – the different colors of light are refracted, or bent at different angles, which separates them into a spectrum,” explains ... The longest and shortest ...

The shortest papal conclave on record took place in October 1503 and lasted only a few hours. Following the death of Pope Pius III, whose reign lasted just 13 days, the cardinals reconvened and ...

Blue light exists on the color spectrum with some of the shortest wavelengths and highest energy. This distinctive property explains both its beneficial and potentially problematic effects on the ...
