Scientists hope to get another glimpse of the rock in June 1999 so the further observations can be made about its movements. This may pin down the exact extent of the threat. The scientists used ultraviolet light to examine the internal organs of an extraordinarily preserved baby therapod dinosaur fossil. Normally internal organs are not preserved in the fossil record, but this examination showed that dinosaurs seemed to have a specialized lung structure that could put large amounts of oxygen into bloodstream so they could suddenly move fast. The layout of the lungs was unlike that of modern birds suggesting that some dinosaurs did not develop into birds as some scientist have suggested.
Sleep paralysis is the state of being awake, but being unable to speak or move.
It usually occurs just as a person is waking up and can last from a few seconds to several minutes. Most people who experience it find it frightening. Others report nightmarish hallucinations. The study indicates that these episodes are usually not linked to any kind of neurological disease. Sleep paralysis occurs because during dreaming-sleep the body keeps itself safe by temporarily paralyzing itself so dreams are not acted out.
