Advanced Optical Materials, EarlyView.Chiroptical properties of DNA‐stabilized silver nanocluster (DNA)2[Ag16Cl2]8+ are presented in linear and nonlinear regime. These water‐soluble, NIR‐emitting nanoprobes demonstrate exceptionally high two‐photon circular dichroism and circularly polarized luminescence brightness.

Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites
Advanced Science, EarlyView.Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.

Early Detection of Cell Death Using Transmembrane Water Exchange Magnetic Resonance Imaging
Advanced Science, EarlyView.Cell death is important in both the development and treatment of cancer. In this study, it is demonstrated for the first time that a specific measurement of the transmembrane water exchange rate using magnetic resonance imaging can be used as an early marker of cell death in mammalian cells, in animals and in human patients. Abstract Cell death plays a

Molecular Jets from an Evolved Protostar: Insights from JWST-ALMA Synergy
The Astrophysical JournalThe combination of the Atacama Large Millimeter/submillimeter Array (ALMA) and JWST/MIRI mid-infrared observations offers a transformative view of protostellar jets and outflows by probing cold and warm gas components across diverse physical conditions ...

Mapping Charge Interactions in Intrinsically Disordered Proteins
Advanced Science, EarlyView.This study presents analytical models to predict intrachain distances in intrinsically disordered proteins (IDPs), accounting for charge patterning, salt concentration, and electrostatic effects. Validated against single‐molecule FRET data, a minimal‐parameter polymer model is identified that captures key interactions and chain dimensions. These models

Flow-based Generative Emulation of Grids of Stellar Evolutionary Models
The Astrophysical JournalWe present a flow-based generative approach to emulate grids of stellar evolutionary models. By interpreting the input parameters and output properties of these models as multidimensional probability distributions, we train conditional normalizing flows ...

Advanced Science, EarlyView.A thin topological insulator (Bi2Te3) inserted between two single magnetic septuple layers of MnBi2Te4 is shown to convert the intrinsic antiferromagnetic interlayer coupling into robust ferromagnetism. As the Bi2Te3 spacer thickness increases from 1 to 4 quintuple layers, the weakening coercivity, Curie temperature, and interlayer coupling reveal ...
