Using a combination of crystallization and physics-based simulations, researchers defined the structure of a protein, cadherin-23, that helps mediate our perception of sound. Their findings show the protein to be a rigid structure whose strength results from calcium ions binding within it. However, mutations that interfere with calcium-ion binding undermine the protein's firm structure and make it less resilient. This provides a possible explanation for certain forms of inherited deafness.Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2023 budget of $9.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
