US-Italy researchers have used quantum-mechanical simulations to resolve a decades-old puzzle about how ultraviolet ...

Light is the fastest thing we know of, so it makes sense to tap into it for ultra-fast communication systems. Fiber optics do just that, allowing us to precisely guide where we want to send messages, ...

Researchers have invented new tools for decoding and controlling signalling circuits in living cells with flashes of light. In principle, any cellular circuit can now be targeted with the new method.

Researchers have revealed a previously unknown way plants shape their growth in response to light—a breakthrough that could better equip crops to handle environmental stress. Subscribe to our ...
