Analysis of the osteochondral unit of aquatic mammals reveals a distinctly different tissue structure, lacking the arcade-like collagen fiber organization, a calcified cartilage layer and a dense subchondral bone plate, typically seen in osteochondral tissue of terrestrial mammals.

Identification of a novel role for the transcriptional repressor, MAF1, and RNA polymerase III-dependent transcription, in osteoblast differentiation, mineralization, and bone biology.

Subterranean fossil bone hosts a living microbiome different from the surrounding sediment without evidence of original protein preservation.

Virtual investigation of the 3.67-million-year-old skull of 'Little Foot' using synchrotron radiation reveals histological details of Australopithecus dental and bone tissues.

Intracellular and interorgan skeletal crosstalk highlights integrative skeletal physiology.

Two therapsid clades, dicynodonts and cynodonts, independently acquired and developed an endotherm-like thermoregulation during the Late Permian period, that probably helped them to survive the major global climate and environmental fluctuations of the end-Permian.

Osteoclasts emerging in inflammation are heterogeneous and encompass a strongly inflammatory subset with a high resorbing activity and an immune suppressive subset that are able to control each other.

Functional and molecular analyses of two distinct skeletal stem cell populations establish the important role of stem cell diversity that provides a framework for novel investigations into skeletal biology.

Editors' Summary: This Replication Study has reproduced some parts of the original paper but other parts could not be interpreted.

Adult spinal fracture substantially impairs subsistence productivity, particularly for men.
