Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing […]

Scientists have uncovered an unusual form of electron behavior in zirconium pentatelluride, a quantum material that can act as both an insulator and a conductor. Under temperatures near absolute zero and magnetic fields reaching 60 […]
The LUX-ZEPLIN experiment has detected a rare particle interaction that looks unusually difficult to explain as ordinary background noise and appeared where dark matter might be expected. Scientists are not claiming a discovery yet, but […]
A search for one mysterious particle unexpectedly revealed evidence for two different structures that may belong to the bizarre family of exotic subatomic particles known as XYZ states. The findings could help physicists uncover new […]
Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely […]
Quantum mechanics and Einstein’s theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A new theoretical framework suggests that some experiments that appear to […]
A major new analysis challenges recent claims that the universe’s expansion is slowing, finding that the evidence for cosmic acceleration remains strong. The findings preserve the leading role of dark energy, while leaving scientists with […]
Today’s mysterious gravitational-wave background may preserve clues about how the Universe’s first supermassive black holes formed. Descendants of hypothetical Dark Stars could be responsible for a major portion of the signal, offering a surprising new […]
A magnetar with an astonishingly powerful magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago. Its light shows signs that supposedly empty space is altering how the light […]
A massive test of gravity across the cosmos found that it behaves almost exactly as Newton and Einstein predicted, even across galaxy clusters hundreds of millions of light-years apart. The result weakens some modified-gravity explanations […]
