NASA-funded research looks to isotope analysis rather than X-ray for measurement Are your bones getting stronger or weaker? Right now, it's hard to know. Scientists at Arizona State University and NASA are taking on this medical challenge by developing and applying a technique that originated in the Earth sciences. In a new study, this technique was more sensitive in detecting bone loss than the X-ray method used today, with less risk to patients. Eventually, it may find use in clinical...

Previous UCSF Research Found Overall Reduction in Spine Fractures, But Not for Other Types of Fractures Continuing a popular but controversial treatment for osteoporosis could reduce spine fracture risk for a particular group of patients, but others could see little to no change if they discontinue it. Based on available evidence, a UCSF researcher reevaluated his 2006 finding from a randomized 10-year study of alendronate, a type of bisphosphonate — a class of drugs that prevent...

Biomedical engineers at Tufts University's School of Engineering have demonstrated the first all-polymeric bone scaffold material that is fully biodegradable and capable of providing significant mechanical support during repair. The new technology uses micron-sized silk fibers to reinforce a silk matrix, much as steel rebar reinforces concrete. It could improve the way bones and other tissues are repaired following accident or disease. The discovery is reported in the Proceedings of the...

(Ivanhoe Newswire) -- Vitamin D is known for helping create strong bones and is a key regulator of serum calcium levels. Recent studies, however, have not offered much proof that Vitamin D supplements prevents bone fractures. Calcium is obtained through diet and absorbed through the intestine and into the blood stream. Calcium is responsible for a variety of physiological processes, not just building bone. Vitamin D is detected by bone and intestinal cell receptors and it regulates the...

(Ivanhoe Newswire) — Biology Major Adam Reese may have found the key to keep fat cells from forming. While investigating new ways to combat osteoporosis, with Assistant Professor Anja Nohe, in the University of Delaware science lab, Reese discovered a trigger that he believes turns a stem cell into a fat cell. The trigger, a protein called endoglin, regulates what type of cell an existing stem cell will become. Reese, with the help of graduate student Joyita Dutta, found the amount...

Here's an anatomical packing list for making that historic trip from water to land circa 370 million years ago: Lungs? Check. Legs? Check. Patches of highly vascular bone in the skin? In a new paper, scientists propose why many of the earliest four-legged creatures that dared breathe on land carried bony skin features. The "dermal bones" within the skin, especially the bones covering the skull roof and forming part of the shoulder girdle, had a highly complex surface of ridges and furrows...
