Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering ...

China's Chang'e-6 samples have uncovered a surprising difference between the Moon's two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth's magnetosphere slows the particles that reach the near side. Noble gases ...

Astronomers have found the first confirmed atmosphere around a rocky planet in another star's habitable zone. The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space. Located 48 light-years away, the world may have .. ...

A newly discovered turning point in the Sun's 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this "switch-off" point, the most violent space weather abruptly ends, and the remaining number of ...

Dying Sun-like stars may not fade away quietly. As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar ...

A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found ...

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing ...

Scientists are testing two promising ways to destroy PFAS, the stubborn "forever chemicals" that can accumulate in water and resist normal treatment. One method uses collapsing vapor bubbles to generate extreme heat and reactive molecules, while the ...

A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems. Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the ...

Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material ...
