Proceedings of the National Academy of Sciences
1 reportProceedings of the National Academy of Sciences is a scientific journal governed by policies for peer review, reporting, data access, corrections, and retractions. Researchers judge the resource through data sharing policy and open access options, with special attention to version status, coverage, and correction practices.
Coverage places corrections and retractions; post-publication scrutiny; and peer-review standards within the wider context of Proceedings of the National Academy of Sciences. For questions involving post-publication scrutiny, the account uses article methods as the measured record and editorial notices to expose uncertainty; the strongest interpretation still recognizes that publication in a prominent venue does not by itself establish consensus.

Reverse Sprinkler Experiments Reveal Angular Momentum Mechanism
Researchers at New York University have built custom rotary sprinklers to investigate the reverse sprinkler problem, measuring how angular momentum and device geometry affect rotation when water is drawn in rather than expelled
