Drugs such as denosumab and teriparatide can be used by anyone with osteoporosis, but are more likely to be recommended for people with unique circumstances, including severe osteoporosis with very low bone density, multiple fractures, steroid use and young age.
Every six years, Earth spins slightly faster and then slower. Cyclic changes in day length overlie decades-long trends. The world turns slightly faster and slower on a regular 5.9-year cycle, a new study suggests. Researchers also found small speed changes that happen at the same time as sudden alterations in Earthâs magnetic field.
Measuring the speed of a rotating object like the Earth is slightly more complicated. After all, if you stand at one of the poles, you'll spin right along with the rest of the Earth, but you'll be stationary with respect to its center. Stand on the equator, though, and you'll have a linear speed of 1,036 miles per hour (1,667 kilometers per hour) [source: Esri ].
