How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

Advanced Materials, EarlyView.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

The ghost of ice ages past: Impact of Last Glacial Maximum landscapes on modern biodiversity

iScience
Summary: Modeled modern and Last Glacial Maximum (LGM) climate ranges for 47 genetically confirmed small Holarctic land snails documented profound landscape dynamism over the last 21,000 years. Following deglaciation, range areas tended to increase by 50%

Comparative Analysis of Mechanical Properties of Arolium and Euplantulae in Medauroidea extradentata (Phasmatodea), Using In Vivo Atomic Force Microscopy, Supports Functional Specialization of both Types of Attachment Pads

Advanced Materials Interfaces, EarlyView.
Stick insects use two different types of smooth attachment pads for locomotion, the pretarsal arolium for adhesion and tarsal euplantulae for friction. With atomic force microscopy (AFM) measurements on these pads on living and conscious insects, this work demonstrates that each pad exhibits distinct material properties aligned with its function.

Corn Zein Nanocarriers for Agrochemical Delivery and Smart Packaging

Advanced Sustainable Systems, EarlyView.
This review explores zein, a corn‐derived biodegradable protein, as a multifunctional nanocarrier for sustainable agriculture and packaging. It examines advances in agrochemical delivery, smart packaging, and stimuli‐responsive systems, while addressing scalability, environmental fate, and regulatory barriers.
