A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

Journal of Field Robotics, EarlyView.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Effect of Magnetic Anisotropy and Gradient‐Induced Dzyaloshinskii‐Moriya Interaction on the Formation of Magnetic Skyrmions

Small, EarlyView.
Magnetic force microscopy of gradient‐induced CoPt films reveals that magnetic skyrmion size and density vary with film thickness, gradient polarity, and applied magnetic field. An increased skyrmion density is observed in films exhibiting higher magnetic anisotropy.

Switchable Exchange Bias Resulting From Correlated Domain Structures in Orthogonally Coupled Antiferromagnet/Ferromagnet van der Waals Heterostructures

Small, EarlyView.
The illustration shows CrSBr/Fe3GeTe2 vdW heterostructure exhibiting two states: a preset‐field‐induced out‐of‐plane spin‐polarized metastable AFM state exchange‐coupled to the saturated FM (top left), and an in‐plane easy‐axis alignment of AFM after demagnetization, which nucleates FM domains (bottom right). The coexistence and switching between these

On‐Tip Polymerization Method for Multimodal Characterization of Nanoparticles with Electron/Ion Imaging and Atom Probe Tomography

Small Methods, EarlyView.
This study presents an on‐tip polymerization method that employs a needle substrate with a designed through‐microchannel (“needle‐eye”) to retain a picoliter‐scale solution of nanoparticles. Using a resin precursor as the solution, polymerization is carried out in situ at the needle tip.

Metastability in Individual Magnetic Vortices at Low Temperatures

Small Structures, EarlyView.
Magnetic vortices are becoming increasingly important for quantum technologies, yet their behavior at low temperatures remains poorly understood. This study employs advanced ion beam nanofabrication and superconducting sensors to measure individual nanodiscs, revealing clear signatures of metastability. By precisely controlling nanoparticle morphology,

Magnetic Manipulation of Spatially Confined Multiferroic Heuslers by Martensitic Microstructure Engineering

Small Structures, EarlyView.
A simple strategy is introduced for promoting the magnetic stray‐field contribution at the surface of epitaxially grown multiferroic shape‐memory Heusler Ni–Mn–Ga thin films and spatially confined structures having negligible magnetic stray‐field contribution.

Visual information in the dark: Bioluminescence and perceptual design through evolution

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bioluminescence offers a powerful framework for understanding how organisms evolve to shape visual information in diverse ways. Complementing studies of colour, transparency and pattern in illuminated environments, bioluminescent systems instead rely on generated light,

Limited inbreeding avoidance at the gamete level despite inbreeding depression in Atlantic salmon (Salmo salar)

Journal of Animal Ecology, EarlyView.
Our study investigates inbreeding avoidance mechanisms at the gamete level in domesticated Atlantic salmon using sperm motility traits assessments, fertilisation trials, and paternity analysis under competitive conditions. We demonstrate that ovarian fluid from sibling females reduces sperm motility traits and fertilisation rates but found no ...
