Physicists probe exotic state of nuclear matter at Europe’s LHC. Findings from Rice University physicists working at Europe’s Large Hadron Collider (LHC) are providing new insight about an exotic state of matter, “quark-gluon plasma” that occurs when protons and neutrons melt. LHC is able to smash together the nuclei of atoms at nearly the speed of the light. The energy released in these collisions is vast and allows physicists to recreate the hot, dense conditions that existed in the early universe...

Two black diamonds on a superconducting chip (12x4mm). The wiggly line is a resonator, coupling the two diamonds.

Atomic defects in diamonds can be used as quantum memories. Researchers at TU Wien have been studying the quantum properties of such diamonds, but only now have they succeeded in coupling the specific defects in two such diamonds with one another. This is an important prerequisite for the development of new applications, such as highly sensitive sensors and switches for quantum computers.

“Unfortunately, quantum states are very fragile and decay very quickly,” explains Johannes Majer, head of the hybrid quantum research group, Institute of Atomic and Subatomic Physics at TU Wien...

A sci-fi staple for decades, laser weapons are finally becoming reality in the US military, albeit with capabilities a little less dramatic than at the movies. Lightsabers—the favored weapon of the Jedi in “Star Wars” films—will remain in the fictional realm for now, but after decades of development, laser weapons are now here and are being deployed on military vehicles and planes. Boeing, Lockheed Martin, Northrop Grumman, Raytheon—all the big defense players—are developing prototypes for the Pentagon. The Navy has since 2014 been testing a 30-kilowatt laser on one of its warships, the USS Ponce.

Lockheed Martin has just announced a 60-kilowatt laser weapon ...

Researchers in AMBER, the Science Foundation Ireland-funded materials science research centre hosted in Trinity College Dublin, have fabricated printed transistors consisting entirely of 2D nanomaterials for the first time. These 2D materials combine exciting electronic properties with the potential for low-cost production. This breakthrough could unlock the potential for applications such as food packaging that displays a digital countdown to warn you of spoiling, wine labels that alert you when your white wine is at its optimum temperature, or even a window pane that shows the day’s forecast.

This discovery opens t...
