Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

An advanced laser has been created using just leaves and peanuts. Scientists made the state-of-the-art technology entirely ...

Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously elusive subatomic particles.

Google’s parent company, Alphabet, is still experimenting with hooking up remote towns to the Internet via frickin’ laser beams. Today, Alphabet’s moonshot “X Lab” shared an update on Project Taara, ...

In a move that sounds like the wildest of science fiction, DARPA has announced its new Persistent Optical Wireless Energy Relay (POWER) program that plans to use lasers relayed by airborne platforms ...

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat. The post shows a green laser beam projected ...

Cryptographic coprocessors are nice, for the most part. These are small chips you connect over I2C or One-Wire, with a whole bunch of cryptographic features implemented. They can hash data, securely ...

A donut is not a bun. From a mathematical point of view, they are two fundamentally different objects: The donut has a hole, the bun does not. A circle inside the donut around its hole in the center ...
