By combining volume sensitive high resolution Magnetic Force Microscopy with surface sensitive X-ray Photoemission Electron Microscopy, we resolved the depth profile of a weak stripe magnetic texture and its evolution upon in-plane magnetization reve

We report unidirectional transmission of micron-wide spin waves beams in a 55 nm thin YIG. We downscaled a chiral coupling technique implementing Ni80Fe20 nanowires arrays with different widths and lattice spacing to study the non-reciprocal transmis

We study the potential of all-electrical inductive techniques for the spectroscopy of propagating forward volume spin waves. We develop a one-dimensional model to account for the electrical signature of spin-wave reflection and transmission between i

Zheng et al. report on the presence of nuclear preservation in the femoral cartilage of a specimen of Caudipteryx, a theropod dinosaur. They identify the presence of chromatin threads for only the second time in any vertebrate fossil.

Calcified cartilage is a vertebrate tissue that has unique characteristics, such as a high percentage of calcification, avascularity and cells with apparently delayed autolytic processes after death. All of these factors suggest that fossilized carti

The fossil record of the reproductive traits of early birds is limited. Here, Bailleul and colleagues describe the Cretaceous enantiornithine bird Avimaia schweitzerae, which preserves an unlaid egg in the abdominal cavity and putative medullary bone

Medullary bone is used by modern female birds as a calcium reservoir for eggshell production. Here, O’Connor and colleagues propose criteria for identifying medullary bone in fossils and report medullary bone from a Cretaceous enantiornithine bird

As key components of the tetrapod pectoral girdle, the scapula and coracoid have played a significant role in the evolution of forelimb locomotion among terrestrial vertebrates. The transition from a rigid fused scapulocoracoid in ancestral non-avian

Gastroliths, where preserved, can provide indirect evidence regarding diet in extinct avian and non-avian dinosaurs. Masses of gastroliths consistent with the presence of a gastric mill are preserved in many Early Cretaceous Jehol birds mostly belong

In the mid-19th century, the discovery that bone microstructure in fossils could be preserved with fidelity provided a new avenue for understanding the evolution, function, and physiology of long extinct organisms. This resulted in the establishment
