Two‐Round Ramsey Games on Random Graphs

Random Structures &Algorithms, Volume 68, Issue 3, May 2026.
ABSTRACT Motivated by the investigation of sharpness of thresholds for Ramsey properties in random graphs, Friedgut, Kohayakawa, Rödl, Ruciński and Tetali introduced two variants of a single‐player game whose goal is to colour the edges of a random graph, in an online fashion, so as not to create a monochromatic triangle.

How Surface Reconstruction Drives Heterogeneous Bulk Delithiation in Single‐Crystalline Ni‐Rich Layered Oxide Cathodes

Small Science, Volume 6, Issue 5, May 2026.
Through multi‐rate operando X‐ray diffraction and soft X‐ray absorption spectroscopy, we demonstrate how surface‐level changes in aged single‐crystalline Ni‐rich LiNixMnyCo1−x−yO2 particles can directly affect bulk Li‐ion diffusion. The effect of this phenomenon on the electrochemical performance is also quantified using single‐layer pouch cells under ...

River Meander Development by Bar‐Push and Bank‐Pull During Cyclic Hydrographs in a Field‐Scale Experimental Channel

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Gravel‐bed rivers widen and narrow as bar‐push and bank‐pull wax and wane through individual floods, yet over decades the channel often holds near constant width, evidence of coupling between inner‐bank deposition and outer‐bank erosion. Because large, event‐scale data sets are scarce and most field rivers have mixed grain‐size beds, the ...

Exorcizing Divergence in Tree‐Ring Density Along the Rocky Mountains

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Briffa et al. (1998), https://doi.org/10.1038/35596 published a seminal paper on the reduced sensitivity of annual tree growth to temperature across Northern Hemisphere treeline stands. By averaging tree‐ring chronologies to sub‐continental means, they found decade‐long trends in maximum latewood density (MXD) progressively diverging from ...

Multi‐Omics Reveals Mechanisms of Metabolic Rejuvenation in Aged Mice and Pre‐Frail Older Men by Losartan

Aging Cell, Volume 25, Issue 5, May 2026.
Losartan partially reversed serum metabolomic aging signatures in both aged mice and pre‐frail older men, and this effect required functional angiotensin II receptors in mice. Cross‐species analyses suggest aging shifts circulating metabolites in opposite directions in mice versus humans, particularly among lipids, with losartan partially normalizing ...
