Rice scientists have discovered that tiny creases in two-dimensional materials can control electrons’ spin with record precision, opening the path to ultracompact, energy-efficient devices.

An artificial intelligence (AI)-assisted model that combines a patient’s MRI, biochemical, and clinical information shows preliminary promise in improving predictions of whether their knee osteoarthritis may soon worsen. Ting Wang of Chongqing Medical University, China, and colleagues present this model August 21^st in the open-access journal PLOS Medicine.

Researchers from the USDA’s Agricultural Research Service are opening new markets for America’s fruit growers. Fruit flies are major economic and quarantine pests that impact fresh fruit production and impede international trade. Flies lay their eggs on fruits, making the infested fruit their host, resulting in millions of dollars in damage annually. For international trade, fruits must undergo quarantine treatment or other mitigation measures to control possible infestation by fruit flies and other high-risk pests. 

Physicists at the Hebrew University of Jerusalem have developed a breakthrough concept in quantum encryption that makes private communication more secure over significantly longer distances, surpassing state-of-the-art technologies. For decades, experts believed such a technology upgrade required perfect optical hardware, namely, light sources that strictly emit one light particle (photon) at a time—something extremely difficult and expensive to build. But the new approach uses innovative encryption protocols applied to tiny, engineered materials called quantum dots to send encrypted information securely, even with imperfect light sources. Real-world tests show it can outperform even the best of current systems, potentially bringing quantum-safe communication closer to everyday use.

A new dataset, the Extensible Building Damage (EBD) dataset, offers significant improvements in disaster response mapping by combining satellite imagery and deep learning techniques.
