CD112 Lactylation Drives Dual Immune Evasion From CD8+ T Cells and NK Cells

Advanced Science, EarlyView.
AARS2 functions as an intracellular lactate sensor and lactyltransferase, catalyzing CD112 K412 lactylation to block ubiquitination‐dependent degradation and stabilize CD112. This pathway suppresses CD8+ T‐cell and NK‐cell cytotoxicity, enabling dual immune evasion.

Combinatorial Survey of Structural Phase Distribution and Magnetism in Fe‐Ge‐Te Composition‐Spread Thin Film Libraries

Advanced Electronic Materials, EarlyView.
ABSTRACT Magnetic 2‐dimensional (2D) van der Waals (vdW) materials have garnered tremendous attention. The vdW ferromagnet Fe5Ge1Te2 has a Curie temperature Tc of ≈ 270 K, which is tailorable by tuning the stoichiometry and the Fe deficiency to reach room temperature.

Cost‐Effective Ti/Al/Ni Multilayer Neural Probes With In Vivo Recording Performance Comparable to Ti/Au Neural Probes

Advanced Electronic Materials, EarlyView.
In this study, we developed a cost‐efficient neural probe by replacing traditional gold with an aluminum‐based Ti/Al/Ni multilayer stack. Optimizing this metal architecture suppressed oxidation and ensured robust electrical stability, achieving signal quality comparable to standard gold probes. It enables a highly accessible and economical solution for

Enhanced Thermoelectric Performance of GeTe‐Sb2Te3 Pseudo‐Binary Phase Change Material Through Stoichiometry Optimization

Advanced Electronic Materials, EarlyView.
A GeTe‐Sb2Te3 composition spread is fabricated using RF magnetron co‐sputtering. Increasing Sb content stabilized the high‐performance cubic GeTe phase. The composition 5Sb3₇Te5₈ exhibited the highest thermoelectric performance, achieving a power factor of ∼1 mW m−1 K−2 and a maximum zT of 0.81 at 300°C.
