Demographic data supporting FDA authorization of AI devices for Alzheimer disease and related dementias

JAMA Network
Peer-Reviewed Publication

About The Study: Transparency of evidence supporting Food and Drug Administration (FDA) authorization of artificial intelligence (AI)- and machine learning -based devices for Alzheimer disease and related dementias was limited, precluding effective evaluation of training and validation dataset representativeness. Disease status (i.e., dementia type and distribution), age, and sex were reported for fewer than half of devices, while race and ethnicity data were rarely disclosed, raising uncertainty about real-world generalizability and clinical accuracy in intended populations.

Biochar improves soil health for cotton production, study confirms

University of Missouri-Columbia
Peer-Reviewed Publication

For generations, farmers have used natural materials such as lime, gypsum and manure to improve their soil for growing crops. Now, a team of researchers led by the University of Missouri is giving new purpose to an established material — biochar, a charcoal-like substance made from leftover plant waste — and showing how it can address challenges facing today’s cotton growers. Even though biochar has been used in various forms of agriculture for thousands of years, this study focused on how it could help cotton farmers in the delta region of the United States, often called the Mississippi Delta.

Phoenix: New open-source program for quantum physics

Universität Paderborn
Peer-Reviewed Publication

Scientists at the Institute for Photonic Quantum Systems (PhoQS) and the Paderborn Center for Parallel Computing (PC2) at Paderborn University have developed a powerful open-source software tool that allows them to simulate light behaviour in quantum systems. The unique feature of this tool, named ‘Phoenix’, is that researchers can use it to very quickly investigate complex effects to a level of detail that was previously unknown, and all without needing knowledge of high-performance computing. The results have now been published in the renowned trade journal ‘Computer Physics Communications’.

From Italy, two new solutions for coral protection: a conductive biopaste and a natural healing patch

Istituto Italiano di Tecnologia - IIT
Peer-Reviewed Publication

A research group in Italy has developed two new coral protection technologies for healing and restoring coral reefs: a biopaste and a natural patch, both successfully tested on real corals. The two solutions resulted from the collaboration among researchers at the University of Milano-Bicocca in Milan, the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) in Genoa, and the Acquario di Genova (Aquarium of Genoa).
