Pasta, a Versatile Transcriptomic Clock, Maps the Chemical and Genetic Determinants of Aging and Rejuvenation

open access: yesAdvanced Science, EarlyView.
Pasta is a transcriptomic aging clock built on an age‐shift learning framework and trained on 17 000 samples across 21 datasets. It accurately predicts relative biological age across tissues, platforms, and species, captures stemness‐to‐senescence transitions, and identifies age‐modulatory perturbations.

Electronegativity‐Guided Site Differentiation in High‐Entropy Alloy for pH‐Universal Hydrogen Evolution Reactions

open access: yesAngewandte Chemie, EarlyView.
Electronegativity‐guided site differentiation is realized in a CoNiCuMoW high‐entropy alloy, where Co/Ni sites optimize hydrogen binding strength, Mo/W sites promote water dissociation, and Cu‐associated sites contribute to balanced hydrogen adsorption.

Evaporation Kinetics Engineering Suppressed Bimolecular Recombination in All‐Polymer Solar Cells

open access: yesAdvanced Science, EarlyView.
In this study, phenanthrene (Ph), a volatile solid additive with a weak tendency toward self‐aggregation, is introduced as a donor‐selective morphology regulator in benchmark all‐PSC systems. The moderate evaporation kinetics of Ph enable cooperative crystallization of donors and acceptors, leading to an increased fractal dimension with reduced donor ...
