Laser-powered 'needle' promises pain-free injections

From annual flu shots to childhood immunizations, needle injections are among the least popular staples of medical care. Though various techniques have been developed in hopes of taking the "ouch" out of injections, hypodermic ...

Scientists discover how to distinguish beams of entangled photons

A team from the Faculty of Physics, MSU, has developed a method for creating two beams of entangled photons to measure the delay between them. In the future the results of the study may be used in high-precision measurements, ...

Reactive optical matter: Light-induced motion

Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...

Graphene plasmons reach the infrared

Graphene's unique properties can be both a blessing and a curse to researchers, especially to those at the intersection of optical and electronic applications. These single-atom thick sheets feature highly mobile electrons ...

Lab sets a new record for creating heralded photons

(Phys.org) —Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. ...

New sensor could help fight deadly bacterial infections

Scientists have built a new sensor that can detect the potentially deadly E.coli bacteria in 15-20 minutes, much faster than traditional lab tests. E.coli can be transmitted in contaminated food and water, posing particular ...
