A study of 5,787 Mpox-related tweets compared epidemic-style models of misinformation spread; an added exposure stage represents delayed sharing, but the burst-heavy dataset cannot validate broad forecasts.
A 2025 gravity-theory analysis offers a possible route for dark energy’s effective density to shift from negative to positive, while observations have yet to confirm that cosmic history.
Researchers created light-triggered, spin-polarized radical pairs inside porous metal–organic crystals, a step toward chemical quantum sensing whose practical performance remains to be established.
A study of 2,546 middle-aged men in eastern Finland found small associations between protein sources and testosterone, but its cross-sectional design cannot show that diet caused the differences or that they affect health.
A multiplexed superconducting detector system reported in Optica extends photon counting beyond 9,000, while its clearest sub-photon precision result reaches 276 photons in laser pulses.
An ETH Zurich team demonstrated a quantum-computing architecture that stores information in mechanical vibrations, completing key algorithms while leaving scale-up and reliability at larger sizes unresolved.
A National University of Singapore team reports a platinum–iron catalyst and regeneration routine that sustained ammonia-derived hydrogen production for more than 2,000 hours in laboratory tests.
