A team at the University of Florida has developed a new kind of computer chip that uses light with electricity to perform one of the most power-intensive parts of artificial intelligence — image recognition and similar pattern-finding tasks. Using light dramatically cuts the power needed to perform these tasks, with efficiency 10 or even 100 times that of current chips performing the same calculations. Using this approach could help rein in the enormous demand for electricity that is straining power grids while enabling higher performance AI models and systems.

Salamanders and chameleons, despite evolving in different habitats, use the same “slingshot” tongue mechanism powered by ordinary tissues, tendons and bone. This biological design could be scaled for human applications, from biomedical devices that clear blood clots to large-scale tools for disaster recovery or space exploration. The findings underscore how nature’s solutions can guide technological innovation.

New power-efficient, lens-based semiconductor chips could help rein in the enormous power draw of AI systems.

How can we make our homes more energy-efficient and resilient to renewable energy fluctuations? A new study in Engineering presents a smart control framework for residential energy systems, combining advanced prediction and flexible control to optimize energy use and reduce costs. Discover how this innovative approach could transform home energy management.

For most broken bones, bone cells regrow on their own while patients wear a cast or brace to keep the injury steady. But for complex or severe fractures, surgeons may intervene by placing grafts or scaffolds made of biocompatible materials, or by using metal fixation devices to ensure proper bone healing and alignment. Collaborating with orthopedic surgeons, a team led by biomedical engineering researchers at Penn State created CitraBoneQMg, an implantable biodegradable scaffold to support bone regrowth made by combining magnesium and glutamine with citric acid. They published research on their implant, for which they filed a U.S. patent application, in Science Advances.
