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.
What's happening inside the body is the heroin is turning into morphine. Morphine has a chemical structure similar to endorphins -- the chemicals your brain makes when you feel stressed out or are in pain. Endorphins inhibit your neurons from firing, so they halt pain and create a good feeling.
