Ultrafast Adhesion/Friction Bidirectionally Switchable Control by Vibration

open access: yesAdvanced Functional Materials, EarlyView.
Bioinspired gradient smooth architectures enable vibration‐switchable adhesion/friction with 62.02 kPa adhesion strength, 131.57 kPa shear strength, tilt angles ≥ 3°, roughness ≥ Ra 0.8 µm, 400 Hz antivibration robustness, and dual‐mode control. The synergy of geometry optimization and vibration modulation tuning bridges multidomain adaptability and ...

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

open access: yesiScience
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%

Use of ethnozoology and environmental education to unveilchildren's conception of anuran amphibians/Utilização da etnozoologia e educação ambiental para desvendar a concepção das crianças em relação aos anfíbios anuros

open access: yesDiversitas Journal, 2020
The absence of knowledge about anuran amphibians can lead to the banal extermination of species. Ethnozoology studies the relationship between human cultures over animals.

Bumblebees land rapidly by intermittently accelerating and decelerating toward the surface during visually guided landings

open access: yesiScience, 2022
Summary: Many flying animals parse visual information to control their landing, whereby they can decelerate smoothly by flying at a constant radial optic expansion rate.

Thiolated Hyaluronic Acid: A Gateway for Targeted Killing of Staphylococcus aureus on the Race for Surface Colonization

open access: yesAdvanced Healthcare Materials, EarlyView.
Thiolated hyaluronic acid (HAMS) synthesized and characterized by NMR, solubility, thiol content, and pKa, is degraded by Staphylococcal hyaluronate lyase but not by mammalian hyaluronidase. Coating polyphosphate–M23 phage endolysin nanoparticles (M23‐PP) with HAMS confers Staphylococcus aureus responsiveness.

Machine learning algorithms can predict emotional valence across ungulate vocalizations

open access: yesiScience
Summary: Vocalizations can vary as a function of their context of production and provide an immediate measure of an animal’s affective states. If vocal expression of emotions has been conserved throughout evolution, direct between-species comparisons ...

The Promise of Solid Lubricants for a Sustainable Future

open access: yesAdvanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Chimpanzees show the capacity to communicate about concomitant daily life events

open access: yesiScience, 2023
Summary: One universal feature of human language is its versatility in communicating about juxtapositions of everyday events. Versatile combinatorial systems of communication can be selected for if (a) several vocal units are flexibly combined into ...

A Canine Musculoskeletal Robot for Investigating Biomechanical Functions During Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
In this study, a dog limb musculoskeletal robot was developed using thin McKibben artificial muscles to investigate the effects of the dog's musculoskeletal structure on walking. Walking experiments were conducted in both indoor and outdoor environments, suggesting that the flexible structure of the dog's shoulders contributes to an increase in stroke ...
