The distribution of climbing chalk on climbed boulders and its impact on rock‐dwelling fern and moss species

Ecology and Evolution, 2020
Rock climbing is popular, and the number of climbers rises worldwide. Numerous studies on the impact of climbing on rock‐dwelling plants have reported negative effects, which were mainly attributed to mechanical disturbances such as trampling and removal

Risk factors and injury prevention strategies for overuse injuries in adult climbers: a systematic review

Frontiers in Sports and Active Living, 2023
IntroductionClimbing is an increasingly popular activity and imposes specific physiological demands on the human body, which results in unique injury presentations. Of particular concern are overuse injuries (non-traumatic injuries).

Potential health benefits and risks associated with bouldering, a sport of rapidly increasing popularity – a literature review

Journal of Education, Health and Sport
Introduction and purpose:   Bouldering is a type of rock climbing activity, which can be practiced on objects usually no higher than 6 meters. It does not require any equipment besides a pair of climbing shoes and chalk, used to enhance the grip ...

Significance of boulder shape for the transport of boulders by tsunamis

, 2021
<p>Physical experiments and numerical models support investigations on the transport of boulders by tsunamis, and based on this, on hydrodynamic characteristics of the tsunami itself. We conduct physical experiments in a flume applying idealized (cuboid) as well as a naturally shaped boulder, the latter representing a downscaled model ...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

Advanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

High‐Throughput Mechanical Rupture of Nuclear Envelope and the Intracellular Dynamics of Massive Wound Repair

Advanced Science, EarlyView.
A microfluidic device with monolithically integrated nanostructures enables high‐throughput wounding of the cell membrane and nuclear envelope. The spatial distribution of charged multivesicular body protein 4B (CHMP4B) within the cell is mapped before and after wounding, showing involvement in repair of both the cell membrane and nuclear envelope ...
