Odorant-binding proteins in canine anal sac glands indicate an evolutionarily conserved role in mammalian chemical communication

open access: yesBMC Ecology and Evolution, 2021
Background Chemical communication is an important aspect of the behavioural ecology of a wide range of mammals. In dogs and other carnivores, anal sac glands are thought to convey information to conspecifics by secreting a pallet of small volatile ...

High Center‐of‐Mass, Multi‐Legged Soft Robots Powered by Geometrically Encoded Liquid Crystal Elastomer Arc Appendages

open access: yesAdvanced Materials, EarlyView.
Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Development of swimming speed-based biomarker reveals interactive toxicity of TCEP and TCPP in amphibian larvae

open access: yesEcotoxicology and Environmental Safety
Tris(2-chloroethyl) phosphate (TCEP) and tris(2-chloro-1-methylethyl) phosphate (TCPP) are increasingly co-detected in various aquatic environments, yet their combined toxicity remains poorly understood.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Identification of tumor-related genes via RNA sequencing of tumor tissues in Xenopus tropicalis

open access: yesScientific Reports, 2023
Cancer treatment is still challenging because the disease is often caused by multiple mutations. Although genomic studies have identified many oncogenes and tumor suppressor genes, gene sets involved in tumorigenesis remain poorly understood.
