Scientists Find Genetic Mutation That Makes Women Feel No Pain (theguardian.com)
An anonymous reader quotes a report from The Guardian: Doctors have identified a new mutation in a woman who is barely able to feel pain or stress after a surgeon who was baffled by her recovery from an operation referred her for genetic testing. Jo Cameron, 71, has a mutation in a previously unknown gene which scientists believe must play a major role in pain signaling, mood and memory. The discovery has boosted hopes of new treatments for chronic pain which affects millions of people globally.
In a case report published on Thursday in the British Journal of Anaesthesia, the UCL team describe how they delved into Cameron's DNA to see what makes her so unusual. They found two notable mutations. Together, they suppress pain and anxiety, while boosting happiness and, apparently, forgetfulness and wound healing. The first mutation the scientists spotted is common in the general population. It dampens down the activity of a gene called FAAH. The gene makes an enzyme that breaks down anandamide, a chemical in the body that is central to pain sensation, mood and memory. Anandamide works in a similar way to the active ingredients of cannabis. The less it is broken down, the more its analgesic and other effects are felt.
The second mutation was a missing chunk of DNA that mystified scientists at first. Further analysis showed that the "deletion" chopped the front off a nearby, previously unknown gene the scientists named FAAH-OUT. The researchers think this new gene works like a volume control on the FAAH gene. Disable it with a mutation like Cameron has and FAAH falls silent. The upshot is that anandamide, a natural cannabinoid, builds up in the system. Cameron has twice as much anandamide as those in the general population.

What I take away from this is yet again, scientific proof that cannabinoid's are good for us. These helpful substances however are banned from our consumption. Thanks, government racist morons!
Humanity is only good at one thing
Yeah, I got you bro!
and that is turning anything and everything into a weapon.
Oh, I thought you were going to say porn. <ahem>
"First they came for the slanderers and i said nothing."
Isn't pain necessary? The woman cuts her foot while walking on the beach and doesn't feel anything. She is heavily bleeding, and keeps smiling because she doesn't feel stress either.

The sources say that a specific woman has been identified as having a genetic mutation that affects her pain response and (from the Guardian):
"Cameron’s mother felt pain normally, as does her daughter. But her son, who carries the second and more important mutation, has a dulled sense of pain. He never takes painkillers and frequently scalds his mouth with hot drinks and food. Scientists suspect that Cameron’s father may have passed the mutation on to her."
Slashdot mutates that in its headline about something that specifically makes women (plural) feel no pain.
Horrible editing. Come on /. even I know the headline is wrong, and English is not my first language.
