Advanced Science, EarlyView.Purposive doping of low electronegative Ba2+ (0.89) at La3+ (1.1) site in LaFe0.7Ni0.3O3‐δ induces the formation of a tri‐phase composite, which shortens Fe─O bond and lowers activation energy, thereby significantly improves electrical conductivity and catalytic activity, and finally offers a record‐high peak power density in La0.5Ba0.5Fe0.7Ni0.3O3‐δ ...

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation
Advanced Science, EarlyView.Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Advanced Science, EarlyView.The uncovered IKKβ‐USP28‐HEY1 axis fuels cancer stemness and immune evasion in hepatocellular carcinoma. USP28 deubiquitinates HEY1 upon IKKβ‐mediated phosphorylation, conferring PD‐1/PD‐L1 blockade resistance. Pharmacological inhibition of USP28 sensitizes resistant tumors to anti‐PD‐1 immunotherapy, revealing a promising therapeutic strategy ...

Advanced Science, EarlyView.Faster phenol photolysis at the air–water interface arises from two cooperative factors: a more favorable initial microenvironment for solvent‐side electron stabilization, which lowers CI access, and a more labile hydrogen‐bond network, which more readily reorganizes to stabilize the dark‐state intermediate.

Surface‐Spin‐Induced Magnetic Loss Enhancement in Ultralight Electromagnetic Absorbers
Advanced Science, EarlyView.Fe3O4 nanoparticles with different hollow rates were synthesized to demonstrate the key role of surface moment in magnetic loss process. Using the same volume filling ratio, the 54.1% hollow Fe3O4 absorber represents about 20% enhancement in the imaginary part (μ'') than solid particles due to the coexisting magnetic resonance of inside and outside ...
