This article reveals how calcium content, mineral nanostructure, and lacuno‐canalicular network (LCN) organization interact to shape bone heterogeneity in mouse tibiae. Advanced multimodal imaging uncovers that mechanical loading promotes mature mineral structures even in low‐calcium regions, highlighting LCN‐driven mineralization and offering new ...

Brightness Behavior of Distant Oort Cloud Comets
Dynamically new comets provide important insights into the conditions of the presolar nebula and its evolution, as they are believed to have experienced minimal solar heating before their discovery.

Point-of-care chest ultrasound in the Neonatal Intensive Care Unit
Chest ultrasound is a useful diagnostic tool in adult emergency medicine. Echography does not generate a clear image of the lung but is able to generate artifacts that are combined in disease-specific profiles.

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

The asteroid (4) Vesta, parent body of the Howardite-Eucrite-Diogenite meteorites, is one of the first bodies that formed, mostly from volatile-depleted material, in the Solar System. The Dawn mission recently provided evidence that hydrated material was

Trabecular bone ontogeny of the human talus
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Search for the True Parent Body of the Phoenicid Meteor Shower
In 2024, Ďurišová et al. found that the meteor shower Phoenicids, IAU No. 254, code PHO, can originate in the nuclei of three comets, 46P/Wirtanen, 104P/Kowal 2, and 289P/Blanpain.

Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Objective Complement component 4 (C4), encoded by C4A and C4B within the major histocompatibility complex (MHC) on chromosome 6, regulates the immune response and clears immune complexes. The variable copy number (CN) of C4 genes and retroviral human endogenous retrovirus K (HERV‐K) element influence its function.
