Lactylation‐Driven PROS1‐TYRO3‐CARF Signaling Promotes Therapy‐Induced Senescence Escape and Radioresistance in Meningioma

Advanced Science, EarlyView.
A glycolysis‐driven epigenetic switch promotes therapy resistance in meningioma. Increased lactate production enhances histone H3K27 lactylation, which activates PROS1 secretion. Secreted PROS1 engages TYRO3 signaling to degrade the senescence regulator CARF, allowing cancer cells to escape growth arrest.

Wood Carbon Sponge/SiO2 Aerogel Composites with Anisotropic Broadband Microwave Absorption, Elastic Resilience, and Thermal Insulation

Advanced Science, EarlyView.
Anisotropic wood carbon sponge/SiO2 aerogel composites are constructed, revealing a robust direction‐dependent permittivity ordering (tangential > radial > axial). The radial direction delivers an ultra‐broadband effective absorption bandwidth of 11.6 GHz at only 4.95 mm, while the tangential direction offers superior compressibility and thermal ...

Monitoring the Microwave Synthesis of d0‐Free Disordered Rocksalt Cathodes Using In Situ Infrared Pyrometry

Angewandte Chemie, EarlyView.
Despite its promise for producing metastable materials, the mechanisms underlying solid‐state microwave synthesis remain poorly understood. By combining in situ thermography with x‐ray diffraction and solid‐state NMR, this study uncovers a surprising order–disorder–order reaction pathway during the microwave synthesis of the Li1.1Mn0.9O1.9F0.1${\rm Li ...

Covalent Organic Framework Colloids With Core‐Shell Donor/Acceptor Architecture and Ultralong‐Lived Charge‐Separated States

Angewandte Chemie, EarlyView.
Uniform core‐shell colloidal particles of Covalent Organic Frameworks (COFs) are synthesized by a seeded growth of electron‐acceptor COF shells on electron‐donor COF cores. The resulting p‐n heterojunction enables efficient separation of photogenerated charges, which persist for minutes. These core‐shell COFs show efficient CO2 photoreduction to CO and
