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 settings, and could pave the way for additional innovative biosignatures to detect disease…"The paper suggests an exciting new approach to the problem," said Dr. Rafael Fonseca, chair of the Department of Medicine at the Mayo Clinic in Arizona, and a specialist in the bone-destroying disease multiple myeloma.
