AI-powered app enables anemia screening using fingernail selfies

A groundbreaking new study introduces an AI-powered smartphone app that noninvasively screens for anemia using a photo of a user’s fingernail. The study shows the app provides hemoglobin estimates comparable to traditional lab tests, with over 1.4 million tests conducted by 200,000+ users. An estimated 83 million Americans and more than 2 billion people globally are at high risk for anemia — populations that stand to benefit significantly from this accessible screening tool. The app offers a low-cost, scalable solution that enhances access, especially in underserved and remote communities, while enabling real-time health monitoring and earlier intervention.

New model for more accurate landslide prediction

Engineers have developed a groundbreaking computational model to study the movement of granular materials such as soils, sands and powders. By integrating the dynamic interactions among particles, air and water phases, this state-of-the-art system can accurately predict landslides, improve irrigation and oil extraction systems, and enhance food and drug production processes.

Bismuth’s mask uncovered: Implications for quantum computing and spintronics materials

Whether bismuth is part of a class of materials highly suitable for quantum computing and spintronics was a long-standing issue. Research has now revealed that the true nature of bismuth was masked by its surface, and in doing so uncovered a new phenomenon relevant to all such materials.

New study shows AI can predict child malnutrition, support prevention efforts

A multidisciplinary team of researchers has developed an artificial intelligence (AI) model that can predict acute child malnutrition in Kenya up to six months in advance. The tool offers governments and humanitarian organizations critical lead time to deliver life-saving food, health care, and supplies to at-risk areas. The machine learning model outperforms traditional approaches by integrating clinical data from more than 17,000 Kenyan health facilities with satellite data on crop health and productivity. It achieves 89% accuracy when forecasting one month out and maintains 86% accuracy over six months — a significant improvement over simpler baseline models that rely only on recent historical child malnutrition prevalence trends.

Hexagons for data protection: Proof of location without disclosing personal data

Location data is considered particularly sensitive — its misuse can have serious consequences. Researchers have now developed a method that allows individuals to cryptographically prove their location — without revealing it. The foundation of this method is the so-called zero-knowledge proof with standardized floating-point numbers.

Researchers develop new metallic materials using data-driven frameworks and explainable AI

Found in knee replacements and bone plates, aircraft components, and catalytic converters, the exceptionally strong metals known as multiple principal element alloys (MPEA) are about to get even stronger through to artificial intelligence. Scientists have designed a new MPEA with superior mechanical properties using a data-driven framework that leverages the supercomputing power of explainable artificial intelligence (AI).

Seeing blood clots before they strike

Researchers have found a way to observe clotting activity in blood as it happens — without needing invasive procedures. Using a new type of microscope and artificial intelligence (AI), their study shows how platelet clumping can be tracked in patients with coronary artery disease (CAD), opening the door to safer, more personalized treatment.
