How the Kisan Mitra Chhadi works, from its 5 to 15-metre detection range to the vibration alert that could help farmers avoid ...

Light usually travels in straight lines, but what if it could twist, spiral, and behave like a miniature tornado? Scientists have now made this possible by creating optical tornadoes (also called ...

Light blocks the brain from making melatonin, the sleep hormone. Light at night can increase the risk of accidents due to daytime drowsiness. Nighttime light exposure can raise the risk of chronic ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

All the info you need right here In this occasion I'll make a lighting system to be controlled remotely from my rc using Arduino compatible boards, they will take the input from a receiver and respond ...

Researchers used a nonlinear metasurface to experimentally demonstrate skyrmions that can be switched between electric and magnetic modes in free-space toroidal terahertz light pulses. Credit: Li Niu ...

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal ...

Have you ever wondered what the invisible world of radio waves might look like if you could actually see it? Rootkid explains how his project, the Spectrum Slit, transforms the unseen chaos of ...

Govee makes just about every kind of light you can think of, and many of those are Matter-capable and able to connect to HomeKit. Earlier this year, Govee came out with a series of Matter star ...

The thin, flexible, wireless device sits next to a quarter for scale. Device emits complex patterns of light (shown here as an “N”) to transmit information directly to the brain. Credit: Mingzheng Wu, ...
