Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics

Advanced Science, EarlyView.
Small nanoplastics can disrupt cell integrity and inhibit cell division in meristem zone of plant root. The plants can counteract the cell damage by upregulating genes associated with root meristem maintenance and increasing auxin accumulation by PIN2 transport inhibition.

Self‐Healing Materials from Electronically Integrated Microscopic Robots

Advanced Intelligent Systems, EarlyView.
Submillimeter robots can use electronically controlled electrodeposition to assemble into a material structure. The resulting aggregate possesses ultralow density, high strength‐to‐weight ratio, and can heal from damage. Further afield, these results clear a path to materials that organize or adapt by directing matter and information at the microscale.

THE ORIGIN OF LIFE: ATMOSPHERIC HYPOTHESIS [PDF]

Filozofia i Nauka
An original hypothesis of the origin of life in an atmosphere of ancient Earth is proposed. It is shown that the atmospheric conditions of ancient Earth had been beneficial not only for initial abiogenic synthesis of organic monomers, but also for their ...

From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

Advanced Intelligent Systems, EarlyView.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Fire avoidance and long‐term population decline in the endangered Florida ground lichen Cladonia perforata within a pyrogenic habitat

American Journal of Botany, EarlyView.
Abstract Premise Fire is a key ecological process that shapes ecosystems globally, yet fire adaptation strategies remain unclear for many species, especially for ground lichens that are reliant on pyrogenic landscapes but are evidently fire‐intolerant.
