AI Article Synopsis
- - The study explores how male Albert's lyrebirds enhance their mating displays by manipulating their physical environment, specifically shaking the vegetation on their display platform.
- - This "stage shaking" occurs in two rhythmic patterns, one of which syncs with the bird's vocalizations during performance.
- - The findings suggest that this behavior is a crucial part of the lyrebird's complex communication and sexual display strategy, shedding light on how environmental manipulation can play a role in attracting mates.
Article Abstract
AbstractWhere dramatic sexual displays are involved in attracting a mate, individuals can enhance their performances by manipulating their physical environment. Typically, individuals alter their environment either in preparation for a performance by creating a "stage" or during the display itself by using discrete objects as "props." We examined an unusual case of performative manipulation of an entire stage by male Albert's lyrebirds () during their complex song and dance displays. We found that males from throughout the species' range shake the entangled forest vegetation of their display platforms, creating a highly conspicuous and stereotypical movement external to their bodies. This "stage shaking" is performed in two different rhythms, with the second rhythm an isochronous beat that matches the beat of the coinciding vocalizations. Our results provide evidence that stage shaking is an integral, and thus likely functional, component of male Albert's lyrebird sexual displays and so highlight an intriguing but poorly understood facet of complex communication.

The inspirations from nature always enlighten us to develop advanced science and technology. To survive in complicated and harsh environments, plants and animals have evolved remarkable capabilities to control fluid transfer sophisticated designs such as wettability contrast, oriented micro-/nano-structures, and geometry gradients. Based on the bioinspired structures, the on-surface fluid manipulation exhibits spontaneous, continuous, smart, and integrated performances, which can promote the applications in the fields of heat transfer, microfluidics, heterogeneous catalysis, water harvesting, Although fluid manipulating interfaces (FMIs) have provided plenty of ideas to optimize the current systems, a comprehensive review of history, classification, fabrication, and integration focusing on their interfacial chemistry and asymmetric structure is highly required.

Soft robots based on actuators that can work in both on-ground and on-water situations are environmentally adaptable and can accomplish tasks in complex environments. However, most current amphibious actuators need external stimuli to move on water and require complex preparation processes. Herein, amphibious Ink-paper/polyethylene programmable actuators and robots are proposed, which are fabricated by rapidly brushing Chinese ink on paper.

2D perovskite has demonstrated great potential for application in photovoltaic devices due to the tunable energy bands, suppressed ion migration, and high stability. However, 2D perovskite solar cells (PSCs) display suboptimal efficiency in comparison to 3D perovskite solar cells, which can be attributed to the quantum confinement and dielectric confinement effects resulting from the intercalation of organic spacer cations into the perovskite lattice. This review starts with the fundamental structural characteristics, optoelectronic properties, and carrier transport dynamics of 2D PSCs, followed by the discussion of approaches to improve the photovoltaic performance of 2D PSCs, including the manipulation of crystal orientation, phase distribution, pure phase, organic layer, and device engineering.

Electrolyte wettability significantly effects the electrochemical performance of lithium-ion batteries (LIBs). In this study, buoyancy testing is employed to accurately measure the force-time curve of electrolyte penetration into the electrodes and thereby calculate the wettability rate. Electrochemical performance is comprehensively evaluated through CR2025 coin half-cell testing, four-point probe analysis, and C-rate cycling experiments.
