BREAKTHROUGH CMOS N-Type Diamond Transistors

Diamond CMOS needs symmetrical doping control like we have for semiconductor silicon and diamond n-MOS is needed. The n-channel diamond MOSFETs are demonstrated. This work will enable the development of energy-efficient and high-reliability CMOS integrated circuits for high-power electronics, integrated spintronics, and extreme sensors under harsh environments. Currently, p-channel diamond MOSFETs have been extensively developed …

Ultraviolet Metalenses Mass Produced. Will Enable Future AI Chips

Extreme Ultraviolet lithography for computer chips have been critical to letting us efficiently get better than 14 nanometer computer chips. Metalenses are 10,000 times thinner than regular lenses. Metalenses control light properties through nanometer-scale patterns or structures on lens surfaces. With the ability to reduce the thickness of conventional lenses by a factor of 10,000, …

Superconducting Magnet Reduces the Cost for a Fusion Reactor by a Factor of 40

A new 20 Tesla Superconducting magnet reduces the cost per watt of a fusion reactor by a factor of almost 40. MIT worked with Commonwealth Fusion Systems, a startup with over $2 billion in funding. The funders of CFS include Temasek Holdings (Singpore), the U.S. Department of Energy, Tiger Global Management, Bill Gates, Google and …

AI Can Now Forget Copyrighted and Other Material

Researchers at The University of Texas at Austin have developed what they believe is the first machine unlearning method applied to image-based generative AI. This method offers the ability to look under the hood and actively block and remove any violent images or copyrighted works without losing the rest of the information in the model. …

How to Optimize the Structure and Quality of Thin Film Nobium for Superconducting Circuits

The performance of superconducting microwave circuits is strongly influenced by the material properties of the superconducting film and substrate. While progress has been made in understanding the importance of surface preparation and the effect of surface oxides, the complex effect of superconductor film structure on microwave losses is not yet fully understood. In this study, …

Diet Control of Isoleucine Increases Healthspan and Lifespan By Up to 33% in Mice

Low-protein diets promote health and longevity in diverse species. Restriction of the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine recapitulates many of these benefits in young C57BL/6J mice. Restriction of dietary isoleucine (IleR) is sufficient to promote metabolic health and is required for many benefits of a low-protein diet in C57BL/6J males. Here, we …
