Four parameters suffice to describe dust attenuation curve diversity in TNG simulations, yielding a new symbolic-regression model that recovers curves and fluxes better than existing parameterizations while linking parameters to SFR surface density, metallicity, and geometry.

Stacked JWST spectra show weak MZR slope evolution to z~5 with declining normalization, steeper MZR beyond z~5, and emerging shallow FMR anti-correlation by z~5.
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.
Extreme z>3 emission-line ratios are reproduced only by combining harder ionizing spectra, ionization parameters from massive star clusters, and enhanced nitrogen abundances.
Spectroscopic observations of six low-mass, metal-poor SLSN host galaxies reveal slow stellar-wind-driven outflows with velocities 37-104 km/s and mass-loading factors below 1 in the earliest phases of star formation.
New high-redshift empirical T_e-based metallicity calibrations for strong-line ratios derived from direct oxygen abundances in 46 galaxies spanning z=1.4-8.7.
New stack-based strong-line calibrations from ~1500 spectra yield mass-metallicity relations at z=1-10 with decreasing metallicity toward higher redshift and no slope change, plus 50 EMPG candidates at 1-4% solar metallicity showing large scatter and opposite sSFR trends.
Two z~6.6 galaxies host overmassive black holes and show remnant ionized bubbles from recent quasar episodes, with BH-to-stellar mass ratios 400-800 times above the local relation.
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 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.
New JWST spectrum of a z=8.3 galaxy with prior ALMA dust detection shows AGN signatures, 0.15 Zsun metallicity, Mdust ~10^6 Msun, Tdust~91 K, and an [OIII] line ratio higher than nebular models allow.
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.
