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 ...

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 ...

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 ...

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 ...

The Parker Solar Probe has flown through the Sun’s atmosphere—an unforgiving environment that poses a number of engineering challenges. An artist’s illustration of the Parker Solar Probe getting up ...

Thanks to a new analysis technique, precision measurements of the Earth-Moon distance should improve estimates of the size of the gravitational-wave background. Precise measurements of the Earth-Moon ...

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 ...

Interest in developing batteries based on sodium has recently spiked because of concerns over the sustainability of lithium, which is found in most laptop and electric vehicle batteries. In the 1870 ...
