21-cm H I emission from the Damped Lyman-alpha absorber SBS 1543+593 [PDF]
, 2001 We detect 21-cm emission from the Low Surface Brightness (LSB) galaxy SBS 1543+593, which gives rise to a Damped Lyman-alpha (DLA) absorption line in the spectrum of the background QSO HS 1543+5921 (z=0.807). We obtain an accurate measure of the velocity

Exploration, EarlyView.Genomic studies implicate RBFOX1 in Alzheimer's disease (AD) risk, highlighting the need to define its role and interactions with other risk factors. Here, CRISPR/Cas9‐mediated RBFOX1 loss in APOE4 human cerebral organoids induces autonomous microglial genesis and accelerates AD pathology, revealing a protective role of RBFOX1 and establishing a model ...
