Global stability analysis identifies rumor control thresholds
This research indicates that rumor spread can be suppressed by changing two reproduction numbers and by targeted interventions that limit contact between ignorant individuals and spreaders while increasing fact-checking.

SLAM estimates M-dwarf stellar parameters from BOSS spectra
This research indicates that a data-driven model can derive metallicity, effective temperature, and surface gravity for Sloan Digital Sky Survey V M dwarfs from low-resolution BOSS optical spectra, with comparisons showing generally good agreement to several reference methods.

Dark decay channels strengthen cosmological bounds on heavy neutral leptons
This research indicates that adding dark sector decay modes to heavy neutral leptons does not evade big bang nucleosynthesis constraints and can make the cosmological bounds stronger.

First ab initio calculation of the fluorine-19 nuclear Schiff moment
This research indicates that the first nuclear Schiff moment calculation for fluorine-19, together with molecular sensitivity calculations for hafnium monofluoride cation, enabled an experimental bound on the fluorine-19 nuclear Schiff moment.

Nonthermal line broadening confirmed in the DM Tau disk
This research indicates that the DM Tau protoplanetary disk has a significant nonthermal contribution to its molecular line width, consistent with turbulence rather than purely thermal motion.
