Isotopic ordering in eggshells reflects body temperatures and suggests differing thermophysiology in two Cretaceous dinosaurs

The evolutionary transitions leading to the modern endothermic state of birds and mammals is unclear. Here, the authors use isotopologues from eggshells to determine body temperatures of females during periods of ovulation, suggesting variability existed between sauropods and the more bird-like oviraptors.

The impact of local pinning sites in magnetic tunnel junctions with non-homogeneous free layers

Pinning sites are extremely detrimental to the frequency tunability of nano-rectifiers based on magnetic tunnel junctions. Here, the effect of pinning defects in vortex-based magnetic tunnel junctions is thoroughly explored, revealing that an amorphous magnetic material utilized as free layer can significantly reduce the impact of pinning.

Multilayer spintronic neural networks with radiofrequency connections

Spintronic nano-neurons and synapses can be connected by radiofrequency signals into neural networks that are capable of classifying real-world radiofrequency inputs without digitization at high speed and with low energy costs—an important step for artificial intelligence at the edge.
