New technique detects bone loss in astronauts, cancer patients

A technique developed in consultation with NASA was initially intended to detect early bone loss in astronauts confined to zero gravity. But, it is also proving much more effective than current tests for determining if patients suffer from bone loss related to osteoporosis or cancer. The technique, which involves a careful analysis of calcium (Ca) isotopes normally present in urine, ultimately could displace the scans now used to detect bone loss in patients at risk for the...
