Cross‐Linking Matters: Atomistic Simulations of the Thermal Degradation of Polymethylsiloxanes

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 1, January 2026.
Atomistic simulations reveal how cross‐linking of polysiloxanes governs degradation pathways, gas evolution, and mass retention. Abstract Utilizing an advanced machine‐learning interatomic potential (MLIP) for Si─C─O─H, the thermal breakdown of polysiloxanes covering polymers from linear polydimethylsiloxane (PDMS) to highly networked ...

Pigments, Chromatophore Structure, and Gene Expression Underlying Colour Polytypy of a Panamanian Poison Frog

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Colour polytypism represents an example of phenotypic diversification shaped by genetic divergence and ecological pressures. Poison frogs of the genus Oophaga (Dendrobatidae) are highly polytypic in coloration, making them an ideal system for investigating the genetic and physiological basis of colour variation.
