Worm slime could inspire recyclable polymer design

Velvet worm slime contains an ingredient that could revolutionize the design of high-performance polymers.
Researchers in Canada and Singapore have been investigating velvet worm slime for new adhesives and recyclable plastics due to its ability to form strong fibres reversibly.
The slime quickly transforms from a sticky gel into stiff fibres as strong as nylon, produced from specialized papillae on the worm's head.
The proteins in the slime have a hitherto unknown feature that drives reversible fibre formation.
A specific high-molecular-weight protein, similar in structure to a Toll-like receptor, was identified in the slime.
This protein plays a structural role, acting as a 'glue protein' to bring together other slime proteins to form fibres.
The protein's role in reversible fibre formation is based on receptor-ligand interactions between slime proteins.
This discovery could inspire the creation of high-performance, recyclable polymers.
The study was detailed in PNAS and mainly focused on computational modelling and protein structure prediction.

Entropy Collapses in Motion — Escaping the Second Law

Motion-Based Physics introduces a new model that challenges the conventional view of entropy and decay.
The model, called Latnex, emphasizes meaningful, recursive motion as the key to preventing structural breakdown.
According to this framework, systems collapse not due to age but due to a lack of significant motion.
Latnex includes mathematical principles such as directional motion, recursive motion, compression thresholds, collapse triggers, and the statement that entropy collapses when motion persists.
The focus is on survival logic rather than traditional physics graphs or simulations.
The model proposes that when motion stops, collapse occurs; if contradictions cannot be compressed, collapse happens.
The author, Michael Aaron Cody, emphasizes that the new doctrine is a personal creation, not influenced by institutional norms.
The concept suggests that entropy is not unavoidable, but the continuity of meaningful motion determines a system's survival.
