Calcium oxalate stones comprise greater than 70% of all kidney stones. In the current conceptual framework, the initial stone ...

Machine learning holds great promise for classifying and identifying fossils, and has recently been marshaled to identify trackmakers of dinosaur ...

The Middle Pleistocene (MP; ca. 774 to 129 ka) marks a critical period of human evolution, characterized by increasing ...

We examine i) whether the public views AI as labor-replacing rather than labor-creating, and ii) how these perceptions affect two core democratic outcomes: democratic legitimacy (e.g., satisfaction ...

Ferroptosis, a form of cell death driven by excessive lipid peroxidation, is induced by inhibiting GPX4, a key regulator of ferroptosis. Wang et al. reported that MALT1 protease activity regulates ...

Bilayer graphene twisted by a small angle shows a significant charge modulation away from neutrality, as the charge in the narrow bands near the Dirac point is mostly localized in a fraction of the ...

Note: The article usage is presented with a three- to four-day delay and will update daily once available. Due to ths delay, usage data will not appear immediately following publication. Citation ...

PNAS depends, in part, on the payment of article processing charges (APCs) to finance its operations. Papers are accepted or rejected for publication and published solely on the basis of merit. For ...

The discovery of high-temperature superconductivity in iron pnictides raised the possibility of an unconventional superconducting mechanism in multiband materials. The observation of Fermi-surface ...

Abstract Extracellular redox-active compounds, flavins and other quinones, have been hypothesized to play a major role in the delivery of electrons from cellular metabolic systems to extracellular ...
