Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and destructive than previously thought, according to new research. Unlike crater-forming impacts, these events unleash extreme heat and pressure without leaving obvious scars, making them harder to detect.

Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded by future space observatories.

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made over 100 years ago and reveals new clues about how black holes spin and launch jets.

AI tools designed to diagnose cancer from tissue samples are quietly learning more than just disease patterns. New research shows these systems can infer patient demographics from pathology slides, leading to biased results for certain groups. The bias stems from how the models are trained and the data they see, not just from missing samples.

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously believed. This breakthrough could make global quantum networks far more powerful, affordable, and practical.

A long-standing physics mystery has been solved with the discovery of emergent photon-like behavior inside a strange quantum material. The finding confirms a true 3D quantum spin liquid and unlocks a new way to study deeply entangled matter.

After a decade of painstaking measurements, scientists have delivered a major plot twist in particle physics: a long-hypothesized “mystery particle” likely doesn’t exist. Using the MicroBooNE experiment at Fermilab, researchers analyzed neutrinos from two powerful beams and found no evidence for a sterile neutrino, ruling it out with 95% certainty.

A mysterious cloud of ultra-hot dust around Kappa Tucanae A may finally have an explanation: a hidden companion star. The star’s extreme orbit carries it straight through the dust zone, strongly suggesting it plays a key role in keeping the dust alive. This finding could help astronomers untangle one of the biggest challenges in imaging

People think online platforms are overflowing with toxic and misleading content, but the reality is far calmer. A small group of highly active users creates most of the harm, while the majority remain relatively civil. Still, many Americans assume the worst about each other because of this imbalance. Correcting that belief can noticeably improve how

Ramanujan’s elegant formulas for calculating pi, developed more than a century ago, have unexpectedly resurfaced at the heart of modern physics. Researchers at IISc discovered that the same mathematical structures behind these formulas also describe real-world phenomena like turbulence, percolation, and even black holes. What once seemed like pure mathematics now appears deeply intertwined with
