A decades-old neutrino mystery might be solved not by undiscovered physics but by improved calculations.

A hallmark property of unconventional superconductivity has been discovered in a type-I superconductor, whereas it’s normally observed only in type-II materials. Superconductors can be broadly ...

Researchers have gained access to the rich physics of a landmark model magnet by assembling a crystal out of organic magnetic molecules. The S = 1 Haldane chain is an infinite 1D string of integer ...

A carbon nanotube foam springs back to its initial state, regardless of the speed of the compression, a property that could lead to a new type of shock absorber. Perfect padding. Vertically aligned ...

The creation of modern quantum mechanics was a messy business in which many of the participants did not grasp the significance of their own discoveries. The wave nature of electrons is revealed in ...

The demonstration that ions can be precisely manipulated in a trap containing integrated photonics paves the way for a large-scale trapped-ion quantum processor. Figure 1: Mordini and colleagues ...

In 1935, Albert Einstein, Boris Podolsky, and Nathan Rosen (EPR) wrote a now famous paper questioning the completeness of the formalism of quantum mechanics. Rejecting the idea that a measurement on ...

Figure 1: Will two objects fall at the same rate in a vacuum? Galileo was the first to test this equivalence principle, and he was followed by many others, including the Apollo astronauts. Now, the ...

A laser-fusion scheme has achieved ignition—an important step on the road to energy production. Figure 1: Artist’s rendering of NIF’s laser beams entering through openings on either end of a hohlraum ...

Particle physicists are faced with a growing list of “anomalies”—experimental results that conflict with the standard model but fail to overturn it for lack of sufficient evidence. For their study of ...

Before determining the correct quantum theory of gravity, researchers need to know if gravity is actually quantized. Experiments testing that assumption are now being developed. Quantum fluctuations ...

Figure 1: An electronic version of a self-contained (autonomous) Maxwell demon. The “system” is a single-electron box connected to an external potential. The demon monitors the charge on the box.
