A team of engineers has designed a new line of multicolored tattoo inks that switch on and off with different kinds of light. Described in a study published in Matter & Light, the technology could one day help people hide their tattoos when they have an important business meeting
A team of engineers has designed a new line of multicolored tattoo inks that switch on and off with different kinds of light. Described in a study published in Matter & Light, the technology could one day help people hide their tattoos when they have an important business meeting. They could even doodle on their own skin using a simple laser pointer.

Quantum chip holds multiple photons at once, opening path to scalable memory
For highly fragile quantum information systems, the ability to store quantum information is vital—but also challenging. Quantum information is transported in particles of light called photons, which often must be temporarily paused (or "stored") while other, slower quantum operat

AI reveals how coating thickness changes the link between surface roughness and pitting resistance
Localized pitting corrosion can cause sudden failure in aluminum components even when overall corrosion rates are low. Steam coating offers a water-vapor-based route to protective boehmite films, but processing simultaneously changes film thickness, surface morphology, crystallin
