THE world’s coral reef ecosystems almost all face a high risk of collapse in the next 50 years, mostly due to warming oceans and heat waves, according to a global assessment released Thursday (Friday in Manila). It’s the latest dose of bad news for coral reefs, which are critical sources…
The world is on track for 2026 to be the second-hottest year on record as an exceptionally strong El Nino weather pattern turbocharges human-driven global warming, the EU’s climate monitor said Friday. This year still has a “20…
Large-area metasurface design requires a balance between electromagnetic accuracy, response reuse, and computational cost. Researchers at Hanyang University and Korea University review unit-cell, supercell, and full-metasurface…

The study, titled “Patient-clinician symptom agreement before and after radiotherapy for prostate cancer: results from the randomized HYPO-RT-PC study,” was published in November 2026 and conducted by Ulrika Rönningås, Lars…
The Swift Observatory’s demise came less than three months after a long-shot rescue mission failed. The U.S. Space Force confirmed Swift’s reentry near Indonesia after tracking its sinking orbit, the result of intense solar activity the past few years. NASA hired a private company to whip together an orbit-boosting effort…
OpenAI recently announced that one of its AI models solved one of the hardest problems in modern mathematics: the Navier-Stokes problem. The equations at the heart of this problem describe the movement of fluids like water and…
The growing capabilities of artificial intelligence (AI) are driving data centers to transfer increasingly large amounts of information between processors. Optical interconnects, which use light for data transmission, can meet…
NASA's Neil Gehrels Swift Observatory has returned to Earth after spending nearly 22 years in space, bringing an extraordinary era of astronomical discovery to a close. The spacecraft re-entered Earth's atmosphere on Wednesday…
