NIF Target Area operators inspect a final optics assembly (FOA) during a routine maintenance period. Each FOA contains four integrated optics modules that incorporate beam conditioning, frequency conversion, focusing, diagnostic sampling, and debris shielding capabilities into a single compact assembly.

(Guido Mieth/Getty Images)Ice characteristicsIce is not constantly ice all the way through. Even at temperatures level well below freezing, its surface area can be coated in a membrane of quasi-liquid atoms, with its density typically only a few nanometers.Its formation procedure is referred to as premelting (or 'surface melting'), which is why your ice...
Entangled drumheads. Credit: Aalto UniversityNew researches expand the boundaries of physics, reaching quantum entanglement in larger systems. Perhaps, even getting around the Heisenberg uncertainty principle.Recently released research pushes the boundaries of crucial concepts in quantum mechanics. Studies from 2 various groups utilized little drums to demonstrate that quantum entanglement. This is an effect generally...
Researchers at Princeton found that a material known as a topological insulator, made from the elements bismuth and bromine, exhibit specialized quantum behaviors normally seen only under extreme experimental conditions of high pressures and temperatures near absolute zero.

In their paper publicized in the journal Nature, the group explains their simulator and exactly how it could be used. Silke Weinfurtner, with the College of Nottingham, has published a...
Facility coordinator Roberto Corsini shows off a 40-metre linear particle accelerator at CERN which could push the boundaries of cancer treatment.

Recently, we ran a piece including the views of well-known science writer John Horgan who talked about a bizarre element of quantum physics confirmed by recent experiments-- that it appears as if there´s no knowledge apart from observers' minds.Theoretical physicist Sabine Hossenfelder is decidedly not happy with that approach:" Physicists have revealed that objective...

Clauser and Anton Zeilinger, during a press...
Droplets of silicon, used to illustrate movements similar to those of quantum particles. Aleks LabudaA solid is made of particles that are, more or less, locked in an ordered framework. On the other hand, a fluid is made of particles that can flow freely around and past each other. However, imagine atoms that stay...
