Direct [OIII]4364-based metallicities show that galaxies with stellar masses 10^6.7-9 solar masses at z~6-8 are 0.3-0.5 dex more metal-poor than local galaxies of the same mass, with slope 0.25 and 0.2 dex scatter.

New empirical calibrations between 19 emission-line ratios and oxygen abundance are derived from direct electron-temperature measurements in 139 star-forming galaxies at z=1.4-10.6.
Analysis of JWST/NIRSpec Prism spectra for 25 z>=10 galaxies finds burstiness correlates with strong UV lines, short depletion times, and DLA-induced redshift biases of 0.39 and 0.14 with marginal impact on UV luminosity density.
JWST spectra reveal that two z~7 galaxies already show near-solar iron-to-silicon ratios with no strong odd-even effect, favoring early Type Ia supernovae over pair-instability supernovae as the source of iron enrichment.
Lower metallicity in high-redshift tori raises the X-ray escape fraction from Compton-thick obscurers, improving prospects for detecting z~10 AGNs.
A review of theoretical models for the first stars and observational strategies including JWST searches, near-field studies, and lensing, noting growing candidates and narrowing parameter space.
