What Apollo 18 Can Teach Us About COVID-19

The Moon mission that never happened illustrates the difference between what we can do, and what we choose to do.

Blackjack: Can a quantum strategy help bring down the house?

Now researchers have shown that the weird, quantum effects of entanglement could theoretically give blackjack players even more of an edge, albeit a small one, when playing against the house.

The art of making tiny holes

It sounds like a magic trick: A highly charged ion penetrates several layers of a material. It creates a big hole in the top layer, but travels through the next layer without damaging it. This new technique can be used to modify surfaces with extremely hight precision.

New method to measure vibrational frequencies in molecular hydrogen ions

An international research collaboration headed by VU-scientist Jeroen Koelemeij developed a new method to measure vibrational frequencies in the molecular hydrogen ion at four hundred times higher precision than before. The results improve the understanding of the fundamental laws of physics and particles such as the proton—topics which have recently been subject to debate. The outcomes of the study were published in Science last week.

Hovering, Flying, and Hopping Across the Solar Sytem

NASA's Mars helicopter is about to take space travel where it has never gone before.

The Correlation-Causation Taboo

Should psychologists be more comfortable discussing causality?

When Dirac meets frustrated magnetism

Scientists have discovered one of the largest anomalous Hall effects (15,506 siemens per centimeter at 2 Kelvin) ever observed in the new compound, KV3Sb5. This material has a never-before-seen combination of properties: Dirac physics, frustrated magnetism, 2D exfoliatability, and chemical stability. Aside from future fundamental research studying the interplay of these ingredients, the unique combination has potential for next-generation computing technologies like spintronics and quantum computing.

Physicists find misaligned carbon sheets yield unparalleled properties

A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing -- and potentially exploitable -- conductive properties. University of Texas at Dallas physicists are studying how the ability of twisted bilayer graphene to conduct electrical current changes in response to mid-infrared light.

When Dirac meets frustrated magnetism

The fields of condensed matter physics and materials science are intimately linked because new physics is often discovered in materials with special arrangements of atoms. Crystals, which have repeating units of atoms in space, can have special patterns which result in exotic physical properties. Particularly exciting are materials which host multiple types of exotic properties because they give scientists the opportunity to study how those properties interact with and influence each other.

Sharing a secret...the quantum way

Researchers have demonstrated a record setting quantum protocol for sharing a secret amongst many parties.
