Transferring Porosity Across Physical States Using Metal–Organic Cages: Porous Liquids, Glasses, Rubbers, and More

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Discrete porous metal–organic cages provide a platform to extend porosity beyond crystalline solids. Their peripheral functionality governs inter‐cage interactions and physical state, enabling preservation of intrinsic porosity across liquids, glasses, and rubbers.

Biological Regulation of Coaxial Calcite‐Aragonite‐Calcite Skeleton Formation in a Deep‐Sea Gorgonian Coral

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Coral biomineralization typically yields either aragonite (in most scleractinians) or calcite (in octocorals), yet the drivers of this polymorph choice remain debated. Here we report a deep‐sea gorgonian coral (Callogorgia sp.) with a coaxial calcite–aragonite–calcite skeleton.

Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic
