As Trump molds military leadership, do politics outrank merit?
When President Donald Trump last month fired six top U.S. military leaders, including a Black man and the United States’ only female four-star officer, he didn’t give a reason. But
Bioinspired ion-shuttling memristor with both neuromorphic functions and ion selectivity
Proceedings of the National Academy of Sciences, Volume 122, Issue 10, March 2025. SignificanceNanofluidic memristors have recently accomplished advanced neuromorphic functions which were not available on solid-state memristors. However, a
Phase transitions in the rolling of irregular cylinders and spheres
Proceedings of the National Academy of Sciences, Volume 122, Issue 10, March 2025. SignificanceWhile the nonslip rolling of regular objects such as spheres and cylinders is treated in all elementary
Giant quantum oscillations in thermal transport in low-density metals via electron absorption of phonons
Proceedings of the National Academy of Sciences, Volume 122, Issue 10, March 2025. SignificanceIn metals thermal conductivity is proportional to electrical conductivity and typically of little interest. Here, we have
A general framework for interpretable neural learning based on local information-theoretic goal functions
Proceedings of the National Academy of Sciences, Volume 122, Issue 10, March 2025. SignificanceWhich learning goals must individual computational elements pursue to contribute to a network-level task solution? This local
Adeno-associated viruses for efficient gene expression in the axolotl nervous system
Proceedings of the National Academy of Sciences, Volume 122, Issue 10, March 2025. SignificanceAmphibians occupy a central position in the phylogeny of tetrapods and serve as a valuable model system
Physics Can Explain How the Inner Ear Picks Up Faint Sounds
Sitting in traffic can expose a driver to intense irritation, as well as a range of sound frequencies. Humming engines typically emit low-frequency sounds, while car horns release high-frequency blasts.
