A team of astronomers using NASA's Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto.
The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system.
A study found that while physical education is recognized as important in preventing childhood obesity, only six states require the recommended amount of exercise for elementary-school students, while only two do so at the middle-school level.

Researchers found that, in most cases, officials set minimums for PE, but do not mandate it.
