As manipulated videos become increasingly difficult to detect with the naked eye, a new study presents an artificial intelligence–based system capable of identifying tampered video frames with high precision, offering a powerful tool to combat misinformation and digital fraud.

Experts found that technological advancements could reduce U.S. mortality from heat by 18% to 25% in the year 2100.

Could mining Reddit with AI help spot drug side effects earlier? A new Penn study suggests it might. Using large language models to map patient posts to standardized medical terms, researchers analyzed more than 400,000 Reddit posts about GLP-1s and found both known side effects and possibly underrecognized symptoms, like menstrual changes. The team says the approach could eventually help generate early safety signals for other drugs and wellness trends discussed online.

Crystals, bacterial colonies, flame fronts: the growth of surfaces was first described in the 1980s by the Kardar–Parisi–Zhang equation. Since then, it has been regarded as a fundamental model in physics, with implications for mathematics, biology, and computer science. Now—forty years later—a Würzburg-based research team from the Cluster of Excellence ctd.qmat has achieved the first experimental demonstration of KPZ behavior on 2D surfaces in space and time. This was made possible by sophisticated materials engineering and a bold experimental approach: researchers injected polaritons—hybrid particles composed of light and matter—into the material. The results have been published in Science.

A University of Houston researcher and his collaborators have developed a mathematical model that helps identify whether a competitive environment is healthy, stagnant or skewed.

Engineers at Princeton have designed and built soft-rigid hybrid robots that move and shift without the need for motors or external pneumatic controls. To do this, the team combined a printable polymer, called a liquid crystal elastomer, with flexible electronics and folding techniques based on the art of origami.
