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.
How fast is Earth moving through space? To begin with, Earth is rotating on its axis at the familiar rate of one revolution per day. For those of us living at Earth's midlatitudes -- including the United States, Europe, and Japan -- the rate is almost a thousand miles an hour. The rate is higher at the equator and lower at the poles. In addition to this daily rotation, Earth orbits the Sun at an average speed of 67,000 mph, or 18.5 miles a second.
