Bone health requires a balanced activity of various bone cell types including bone-forming osteoblasts and bone-resorbing osteoclasts. Osteoporosis occurs when osteoclasts dominate without adequate bone formation to compensate. In new research published in the Journal of Bone and Mineral Research, elevated blood levels of a certain chemokine, or small signaling protein, that promotes osteoclast formation were linked with a higher risk of hip fracture in men.

Perovskite films, which combine organic and inorganic materials, have been under suspicion by scientists since 2009 as a potential material for solar panel manufacturing. In contrast to silicon wafers, perovskites are extremely thin films with a particular crystal structure that is efficient, lightweight, and inexpensive.

Elementary school-age children who get less than nine hours of sleep per night have significant differences in certain brain regions responsible for memory, intelligence and well-being compared to those who get the recommended nine to 12 hours of sleep per night, according to a new study led by University of Maryland School of Medicine researchers.

According to ARRS' American Journal of Roentgenology (AJR), for patients with multiple architectural distortion (AD) identified on digital breast tomosynthesis (DBT), biopsy of all areas may be warranted, given the variation of pathologic diagnoses across AD in individual patients.
