So, what we’re dealing with here, to go back to the very beginning, are little carp, Garra ruffa.
The fish eat skin because food can be scarce in the warm pools they live in, and because their little jaws are toothless, they’re only able to eat dead skin. See, apparently our skin is constantly producing “endocannaboids,” substances not unlike the active ingredients in marijuana.
A new study examines the function of endocannaboids in the skin, and how that might be linked to their presence in the brain. The skin seems to produce these marijuana-like chemicals as a response to environmental stresses like wind and sun. The brain produces similar chemicals in response to stressors and rewards, and they make us feel anxious, or pleased, or whatever.
As far as getting high from licking your arm goes…well it’s theoretically possible that endocannaboids could do the trick, but even if you were to, say, eat your whole arm, there wouldn’t be enough there to give you any psychological effect. Embryo, 8 cellsCourtesy EkemLast week we learned that scientists cloned human embryos using adult skin and fertile eggs from a woman donor.
Unlikely cure: Not only does it look weird, but new research finds that duct tape is not the best way to get rid of warts.
That study was done in 2002, but a new study done over a larger group of subjects showed that duct tape worked only 21 percent of the time in dissolving warts.
But the new study found that duct tape was no more effective in treating warts than moleskin bandages, which are a cotton tape bandage similar to a Band-aid.
According to the experts in the field, the best way to treat warts is to use over-the-counter topical treatments that contain salicylic acid. The part of your brain that receives information from your sensory neurons doesn't treat all parts of the body equally.

Or, really, I suppose they’d eat flesh from anywhere, but what they’re getting is foot flesh. The carp are native to rivers across the Middle East, and are kept and bred in outdoor pools in Turkish spas. Endocannaboids help glands in the skin produce the oily substances that protect us from the elements, and which also contribute to pimples and hair loss. Psychological stress, however, may prompt the skin—as well as the brain—to start producing these chemicals, which lends credence to the thought that stress can cause acne and influence baldness.
Now the Human Fertilization and Embryology Authority in Britain has approved creating human embryos using eggs from animals like cows or rabbits. Researchers hope to refine their techniques by practicing first on animal eggs to producing human stem cells. Stem cells from cloned embryos could provide a valuable tool for studying diseases, screening drugs, and creating transplant material to treat conditions like diabetes and Parkinson's disease. This procedure requires cutting healthy eggs out of women, then altering them to produce living embryos, which are then destroyed. 04th, 2007Researchers at Stanford University have discovered a protein that contributes to skin aging.
The new study found it effective only 21 percent of the time.I’m sorry to tell you this Red Green, but you might want to clean out that duct tape in your medicine cabinet. You might remember all the hubbub a few years ago that said the best way to get rid of warts was to put a piece of duct tape on the warty area and they would soon be dissolved away. They’re in a place that’s hard for our bodies immune system to get its antibodies to attack the virus. If so, you've probably noticed that some parts of your body are more ticklish than others. The reason you are more sensitive on your fingertips than your elbow is that there are many more sensory neurons on your fingertips.

Also, why would one choose a projection centered on the Atlantic and all of those passive margins when a Pacific (ring of fire) centered projection would match the inset cross-section much better?

The fish are also recommended as an alternative treatment for psoriasis, but you might have to cross an ocean to get to a pool full of psoriatic plaque-gulping fish.
Because the animal cell's nucleus would be removed before human DNA was added, scientists said the resulting egg would not be a chimera.
Human stem cells, which have the ability to develop into any cell in the human body, show promise for understanding and healing many human ailments.
The original theory behind the duct tape treatment concept was that rubber on the sticky side of the duct tape would irritate the skin enough to stimulate antibodies to go to the wart and kill it off.
When an area has more sensory neurons there is a larger brain area devoted to receiving their signals, meaning more sensitivity. I mean, Tyra Banks, Eastern Europe, and big chunks of Asia are already all about flesh-eating fish. Smack yer little babies’ thumbs out of their mouths and replace them with something a little more legal, like cigarettes! If anything, what you need is a hole-cutting drill bit and a melon baller, because it’s your brain that produces the most endocannaboids. Thanks to your skin receptors, you can feel a soft fleecy blanket, a cold splash of water or a sharp pinch—ouch! Sure, Tyra Banks is a little wiser than most people, and I can’t remember a time when Eastern Europe wasn’t dancing on the cutting edge, but that doesn’t mean I have to feel good about it.
