摘要:Maternal antibodies fundamentally regulate gut immunity in the developing infant, yet the mechanisms underlying this process remain elusive. We found that maternal immunoglobulin G (IgG), ingested in the first week of life, restrained microbiota-dependent adaptive immune responses weeks later, after weaning. This activity was linked to maternal antibodies that could bind bacteria in the neonatal gut and the ability of microbe-IgG complexes to engage Fc and complement-dependent effector functio...

摘要:An inertial confinement fusion experiment, carried out at the National Ignition Facility, has achieved ignition by generating fusion energy exceeding the laser energy that drove the experiment. Prior to the experiment, a generative machine learning model that combines radiation hydrodynamics simulations, deep learning, experimental data, and Bayesian statistics was used to predict, with a probability greater than 70%, that ignition was the most likely outcome for this shot.

摘要:In multilayer moir & eacute; heterostructures, the interference of multiple twist angles ubiquitously leads to tunable ultralong-wavelength patterns known as supermoir & eacute; lattices. However, their impact on the system's many-body electronic phase diagram remains largely unexplored. We present local compressibility measurements revealing numerous incompressible states resulting from supermoir & eacute; lattice-scale isospin symmetry breaking driven by strong interactions. By using the sup...

摘要:The stable isotopic composition of microbial methane varies substantially, and the underlying causes are debated. In this work, we experimentally controlled the abundance of the central enzyme in methanogenesis, methyl-coenzyme M reductase (MCR), in Methanosarcina acetivorans and tested whether its cellular concentration alters methane isotopic compositions. We found that during growth on methanol and acetate, lowering the expression of mcr increases the degree of hydrogen isotope exchange bet...

摘要:Copper-catalyzed radical C(sp3)-N coupling has become a major focus in synthetic catalysis over the past decade. However, achieving this reaction manifold by using enzymes has remained elusive. In this study, we introduce a photobiocatalytic approach for radical benzylic C(sp3)-N coupling using a copper-substituted nonheme enzyme. Using rhodamine B as a photoredox catalyst, we identified a copper-substituted phenylalanine hydroxylase that facilitates enantioconvergent decarboxylative amination...
