Effect of phantom decoys in herbivore foraging

, 2023
In foraging ecology, models of food choice usually assume animals are economically rational, using an absolute valuation system, wherein they choose food with the highest net worth and ignoring irrelevant alternatives (e.g., lower value items). However, studies have found that animal decisions can be influenced by the specific composition of a choice ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Machine Learning–Assisted Bio‐Interfacial Engineering Resolves Structural–Functional Conflicts in Nanocomposites

Advanced Materials, EarlyView.
A machine learning‐guided bio‐interfacial design strategy resolves the long‐standing strength–toughness–functionality trade‐off in nanocomposites. By efficiently mapping high‐performance regions in the composition–processing space, the approach delivers hierarchically entangled, nanosheet‐pinned architectures that combine mechanical robustness ...

An Energy Focusing Flexible and Lightweight Acoustic Metamaterial for Enhanced Ultrasound Power Transfer

Advanced Materials, EarlyView.
A flexible and lightweight acoustic metamaterial composed of air cavities encased in polydimethylsiloxane (PDMS) is introduced to enhance ultrasound power transfer. The metamaterial leverages the strong reflectivity of air cavity boundaries to concentrate incoming ultrasound, thereby improving the performance of piezoelectric energy harvesters ...

The Coupling of Ferroelectric Polarization and Oxygen Vacancy Migration Enables Electrically Controlled Thermal Memories

Advanced Materials, EarlyView.
Ferroelectric Hf0.5Zr0.5O2 epitaxial thin films exhibit a non‐volatile, electrically controlled thermal conductivity enabled by the coupling between oxygen vacancy migration, acting as phonon scatterers, and ferroelectric polarization, acting as ion migration valve.

Photochemical Fuel Carrier Molecules for Robotic Embodied Energy

Advanced Materials, EarlyView.
We designed a novel fuel carrier photoresponsive molecule for on‐demand energy storage and release. Carrier molecules undergo bond scission under UV light to release chemical fuel and locally generate propulsive Marangoni flows. We demonstrate this photochemical embodied energy strategy in small‐scale robots and active matter systems, enabling ...

Efficacy of increased visual and olfactory cues for luring and trapping invasive tegu lizards

Frontiers in Amphibian and Reptile Science
Controlling invasive wildlife species relies on the ability to efficiently remove individuals from the invaded environment. Thus, maximizing capture potential is of high interest, particularly for species that are difficult to capture.

Liquids as Reinforcements for Anisotropic and Tough Soft Matter Composites

Advanced Materials, EarlyView.
Liquid metal droplets are shaped and oriented within soft elastomers to create all‐soft matter composites with programmable mechanical anisotropy. These liquid inclusions act as fiber‐like reinforcements, enabling directional stiffness, enhanced toughness, and controlled crack steering under extreme deformation, offering new routes to resilient soft ...

Decoy effect and host infection by miracidia within snail communities

Parasitology, 1993
SUMMARYThe effect of experimental non-host snail (NHS) communities on the infection of Lymnaea truncatula with Paramphistomum daubneyi and Fasciola hepatica miracidia was studied. The results obtained indicated that NHS had variable effects on basic population parameters of host infection. Specifically, NHS were able to produce aggregation of sporocyst
