Magnetoactive Metamaterials: A State‐of‐the‐Art Review
Magnetoactive metamaterials combine magnetoactive composites with architected metastructures to enable contactless, tunable control of mechanical, acoustic, and elastic properties. This review highlights recent advances in their design, fabrication, and applications in soft robotics, biomedical devices, and adaptive structures and outlines future ...

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.

Could photoperiodic responses have evolved before the emergence of circadian clocks?
Summary Plants use photoperiod (i.e. day length) as a seasonal cue for timing when to flower. This ability, known as photoperiodism, also underlies phenomena such as migration, seasonal reproduction, and hibernation in animals. Because a circadian (daily) clock underlies the day/night length timing mechanism in most organisms, it has been generally ...

Machining and Performance Testing of Inclined Double-roller Enveloping Hourglass Worm Drive
To eliminate the gear backlash,a new inclined double-roller enveloping hourglass worm drive is proposed. The meshing performance is analyzed based on the meshing geometry of inclined double-roller enveloping hourglass worm drive.
