Cosmological zoom-in simulations find that grain-grain shattering in diffuse ISM gas drives rising PAH mass fraction with time, naturally producing the observed PAH-metallicity relation and inverse qPAH-molecular gas trends.

Measures a new nebular attenuation curve from 1400-9550 Å for galaxy GOODSN-17940 at z=4.41 that is steeper than Milky Way/SMC/Calzetti at long wavelengths, similar in blue-optical, and shallower in UV with no 2175 Å bump.
Massive galaxies at z>3.5 assembled stars earlier than theoretical models predict and exhibit gray dust attenuation, especially at the highest masses.
A z=4.556 QSO exhibits A_1500/A_V ≈8 with no 2175Å bump, taken as evidence for small-grain dominance from QSO-driven shattering or condensation.
JADES DR5 delivers 2081 z_phot > 8 galaxy candidates with UV slope trends, morphological evidence of clumpy growth, and improved photo-z methods tested on a spectroscopic subsample.
Strong-feedback models with bright galaxies match JWST UVLF at z greater than or equal to 10 and predict an extended reionization from z approximately 16 to 6 that fits CMB optical depth within 2 sigma.
Simulations predict ngVLA at 100 GHz can detect galaxies above 10^9 solar masses at any redshift while SKA low frequencies reach massive dusty galaxies to z=5-7.
The document records key conclusions, challenges, and open questions from discussion sessions at a 2025 conference focused on interstellar, circumstellar, and galactic dust with emphasis on JWST and ALMA results.
