A satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth).
Natural chemical 'beats morphine'. The natural chemical was able to relieve pain like morphine. The human body produces a natural painkiller several times more potent than morphine, research suggests. When given to rats, the chemical, called opiorphin, was able to curb pain at much lower concentration than the powerful painkiller morphine. The French team said their findings could be lead to new pain treatments.
Endorphins are one of the most natural ways to feel good. Not only are endorphins thought to block the sensation of pain, but they also work to lower stress levels and support the immune system. Some studies have indicated that they can cause certain cells, called natural killer cells, to be triggered. Once those cells are stimulated, they work to fight cancer cells.
