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 Active Denial System (pain ray) is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 Â°F (54 Â°C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting damage.
