PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

open access: yesAdvanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

Phase Diagrams and Piezoelectric Properties of Wurtzite Al1−x−yScxGdyN Heterostructural Alloys

open access: yesAdvanced Science, EarlyView.
This study demonstrates ferroelectricity and piezoelectric properties improvement of quaternary wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films, guided by density functional theory calculations. Wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films have a high optical bandgap, enhanced piezoelectric ...

Adhesion‐Related Macrophages Regulate Metabolic Homeostasis Through CAV‐1 Dependency

open access: yesAdvanced Science, EarlyView.
Adipose tissue harbors a distinct macrophage subpopulation, termed adhesion‐related macrophages (ARMs), which stably adhere to adipocytes. In obesity, ARMs represent the major expanding macrophage subset. They acquire material from adipocytes and rely on Caveolin‐1 for sustained lipid handling.

Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi

open access: yesAdvanced Science, EarlyView.
Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

Light‐Harvesting Photothermal Hotspots Enabled by NIR Scattering‐Absorption Coupling

open access: yesAdvanced Science, EarlyView.
By coupling the broadband scattering of nanodiamonds with the plasmonic absorption of gold nanostars, this work proposes a novel strategy for the active modulation of photon transport. This strategy creates localized photothermal hotspots in turbid media and achieves a supra‐additive heating efficiency, thereby providing a universal platform for low ...

Mitochondrial Enzymes Mimetic Ultrasmall Palladium Nanozymes Prevent Senescence and Neurodegeneration Through Metabolic Reprogramming

open access: yesAdvanced Science, EarlyView.
Simply constructed polyvinylpyrrolidone (PVP) modified palladium nanoparticles (PdP NPs) as cytochrome c oxidase (CcO) and superoxide dismutase (SOD) mimic are promising multifunctional nanoreactors to boost mitochondrial respiration chain function and refine homeostasis via regulation of mitochondrial dynamics and proteostasis sensor UPRmt, which ...

Affinity‐Based Interactome Mapping of Inositol Pyrophosphates Reveals 4/6‐PP‐InsP5‐Binding Proteins in Plants

open access: yesAdvanced Science, EarlyView.
ABSTRACT Inositol pyrophosphates (PP‐InsPs) are central regulators of eukaryotic signaling events. While certain PP‐InsP isomers have been conclusively linked to the regulation of phosphate homeostasis through interaction with SPX domain‐containing proteins in plants, the functions of the recently discovered isomer 4/6‐PP‐InsP5 remain largely unknown ...
