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 ...

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 ...

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 ...

Which direction would an S-shaped lawn sprinkler rotate if it were submerged and the flow were reversed? Experiments now provide a definitive answer. A fluorescent dye traces out the flow pattern as ...

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 ...

A new theory related to the second law of thermodynamics describes the motion of active biological systems ranging from migrating cells to traveling birds. Figure 1: A biological cell (black outline) ...

Gravitational waves emitted by the merger of two black holes have been detected, setting the course for a new era of observational astrophysics. Figure 1: Numerical simulations of the gravitational ...

A “Little Earth Experiment” inside a giant magnet sheds light on so-far-unexplained flow patterns in Earth’s interior. Sketch of outer-core flows derived from data from the Swarm mission (plotted ...

When a cloud of cold atoms goes through a supersolid phase transition, its coexisting superfluid and crystalline phases do not emerge simultaneously. Figure 1: (Left to right) The solid and superfluid ...

The new JWST observatory is revealing far more bright galaxies in the early Universe than anyone predicted, and astrophysicists have more than one explanation for the puzzle. With the JWST observatory ...
