Medication found to 'reduce acceleration of bone loss'
Researchers in Canada have discovered that antiresorptive medication could help reduce risk of hip fracture in older men and women. ... Continue Reading
Bone mineral density an 'effective predictor of mortality'
Low bone mineral density in the hand can serve as a prognostic indicator of mortality in patients with rheumatoid arthritis, a new study suggests. ... Continue Reading

Dental Crowns Reveal The Diet Of A Species
According to recent research, the complexity of tooth surfaces reveals the diet of a species. Scientists at the University of Helsinki's Institute of Biotechnology and Department of Geology showed that the more complex the surface of an animal's teeth, the greater the share of vegetables in its diet. For instance, the teeth of carnivores and rodents differ in almost every aspect, but if a carnivore and a rodent eat similar food, their teeth are equally complex. The results were published in Nature. ... Continue Reading
Depression drugs weaken bones in elderly: study
Older adults who take the most popular class of anti-depressant drugs worsen their risk of developing fragile bones, a study said on Monday. Tests on a group of Canadians aged 50 or older found those taking selective serotonin reuptake inhibitors had 4 percent less bone mineral density in their hip bones. Millions of people take the anti-depressants commonly called SSRIs that include Eli Lilly's Prozac. ... Continue Reading
Dieting without exercise harms bone health
Men and women who lose weight through caloric restriction, without exercise, also lose bone at the hip and spine, increasing their risk for the bone-thinning disease osteoporosis and fractures, a study shows. Adding regular exercise to a calorie-restricted diet helps shield the bones from the harmful effects of dieting. "Exercise protects against bone loss during voluntary weight loss," Dr. Dennis T. Villareal, who led the study, told Reuters Health. "Therefore, it would be important to combine calorie restriction and exercise to derive the benefits of weight loss and preserve bone." ...

The American Dental Association, in a recently published position statement, says that mothers should be careful not to prepare baby foods with fluoridated water from the tap, as the fluoride contained in it could be bad for developing babies' teeth. ... Continue Reading
Scientists See With X-rays How Bones Resist Strain Thanks To Their Nano And Micro Structure
Scientists from Max Planck Institute (Germany) and the ESRF have just discovered the way deformation at the nanoscale takes place in a bone by studying it with the synchrotron X-rays. This study explains the enormous stability and deformability of bones. The hierarchical structure of bones makes them able to sustain large strains without breaking, despite being made of essentially rigid units at the molecular level. The results are published this week in the PNAS online edition. ... Continue Reading
