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.
JWST prism spectroscopy of 200 massive galaxies at z~3-15 shows normal star-forming galaxies dominate at z>6 while dusty systems and quiescent galaxies increase at lower redshift, with evidence for multiple quenching pathways.
New spectroscopic data on young clusters in NGC 5253 indicate younger ages than photometric estimates and reveal correlations between outflow velocities and cluster properties, showing supernova feedback active at ages over 5 Myr in a 0.3 solar metallicity environment.

A Glimpse of the Low-Mass End of the Direct Mass-Metallicity Relation at $z\sim6-8$
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.

Spectroscopic characterization of Young Stellar Populations and their Feedback in NGC 5253
New spectroscopic data on young clusters in NGC 5253 indicate younger ages than photometric estimates and reveal correlations between outflow velocities and cluster properties, showing supernova feedback active at ages over 5 Myr in a 0.3 solar metallicity environment.
