Thermal Transistors Handle Heat With No Moving Parts
Electronic transistors are central to modern electronics. These devices precisely control the flow of electricity, but in doing so, they generate heat. Now, researchers at the University of California Los Angeles have developed a solid-state thermal transistor—the first device of its kind that can use an electric field to control the flow of heat through…

Second-most distant galaxy discovered using James Webb Space Telescope
The second- and fourth-most distant galaxies ever seen (UNCOVER z-13 and UNCOVER z-12) have been confirmed using the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). The galaxies are located in Pandora’s Cluster (Abell 2744), show here as near-infrared wavelengths of light that have been translated to visible-light colors. The scale of the main cluster image…

When accuracy matters: MAS Diabetes quality controls
Diabetes the Disease Diabetes is a chronic health condition that affects the metabolism of individuals. Diabetes is caused by the body’s inability to make insulin or make enough insulin. When there is inadequate insulin produced by the body, blood sugars tend to raise and over period of time with increased sugar in the blood stream,…

A robot inspired by mantis shrimp to explore narrow underwater environments
The structure of the bionic mantis shrimp robot. Credit: Chen et al. (IEEE/ASME Transactions on Mechatronics, 2023). Nature is the primary source of inspiration for many existing robotic systems, designed to replicate the appearance and behavior of various living organisms. By artificially reproducing biological processes, these robots can help tackle complex real-world problems more effectively.…

The archaeologists saving Africa’s ironworking heritage | Feature
For more than a decade, Tanzanian archaeologist Edwinus Lyaya has been searching for traces of an African technology – and tradition – that he worries is ‘disappearing without notice’. In his home country and neighbouring Zambia, in the Great Lakes region of eastern Africa, he has often focused his search on the western side of…

Predicting Therapy Success With IRON
Results from a study published in the journal Nature Communications, co-designed and co-supervised by Prof. Evis Sala from the Catholic University at Rome, and Policlinico A. Gemelli IRCCS. A model based on artificial intelligence is able to predict the therapy outcome (measured by volumetric reduction of tumor lesions) in 80% of ovarian cancer patients. The…
