The secret microstructure of bone: Insights into what makes it stiff and tough
The detailed structure of bone on a microscopic scale has been revealed. Bone is an impressive natural material because it combines properties which are usually mutually exclusive -- stiffness (for support and leverage) and toughness (for protection and resisting impacts). (2018-05-03)

UAB-led study shows drug effectiveness in reducing glucocorticoid-induced bone loss
About one in every 100 people in the world takes glucocorticoids long term to treat immune-mediated diseases. However, glucocorticoids, such as prednisone, have a side effect -- they induce glucocorticoid-induced bone loss, causing an estimated yearly bone fracture rate of 5 percent. An alternative treatment option to the standard treatment now appears promising, according to an international study. Researchers compared the monoclonal antibody denosumab against a standard bisphosphonate. (2018-04-27)

New light shed on how bone marrow niches keep stem cells thriving
Hematopoietic stem cells (HSCs) require specialized niches in bone marrow to generate functional blood cells. CAR cells are among cell types located in niches, but their function is poorly understood. Researchers identified a protein, Ebf3, in CAR cells that is needed to maintain the bone marrow cavities and the HSC niche. With no Ebf3, HSC abundance is greatly reduced, and bone overgrowths fill the cavities forming the niches. The finding offers a new therapeutic target for bone and blood disorders. (2018-04-18)

Charge density wave inhomogeneity and pseudogap in 1T-TiSe2
1T-TiSe2 undergoes the superconductivity transition under Cu intercalation, pressure or electric gating. However, the interplay between CDW and superconductivity is still under debate. Researchers at Nanjing University recently demonstrate the dopant-induced CDW inhomogeneity and pseudogap state in 1T-TiSe2 by using scanning tunneling microscopy and spectroscopy. The CDW inhomogeneity gives rise to the reduced CDW gap with 2x2 superstructure persisted, while the pseudogap state may be related with the pre-formed Cooper pair. (2018-04-18)

Human stem cells have shown potential in medicine as they can transform into various specialized cell types such as bone and cartilage cells. The current approach to obtain such specialized cells is to subject stem cells to specialized instructive protein molecules known as growth factors. However, use of growth factors in the human body can generate harmful effects including unwanted tissue growth, such as a tumor. (2018-04-13)

NIH researchers crack mystery behind rare bone disorder
Researchers at the National Institutes of Health worked with 15 patients from around the world to uncover a genetic basis of 'dripping candle wax' bone disease.
