Tattoos may permanently alter the physiology of skin in ways that affect sweating. According to a small, new study, the amount and saltiness of sweat change after skin has been dyed, a finding that might have implications for athletes who ink large swaths of their bodies and maybe even for those of us who sport one or two discreet tattoos (such as the small one on my right shoulder, in case you were wondering). Tattoos are decorative, often metaphoric, sometimes regrettable, but always injurious. To create a tattoo, the artist punctures the skin with dye-filled needles at a rate of up to 3,000 times per minute. The dye is injected into the skin’s dermal layer, which is also where most sweat glands are. The body recognizes these injections as abnormal. They have slightly damaged the tissue and left behind a foreign substance, the ink. So the immune system gears up, sending a variety of cells to the site of the inking. Some cells carry off tiny amounts of the ink, primarily to...

Practicing tai chi helps older people improve their balance and avoid falls, a review of studies has found. Tai chi is a form of Chinese martial arts now practiced as exercise. It involves a specific program of graceful movements, accompanied by deep breathing and mental focus, that slowly move the center of balance from one leg to the other. Researchers found 10 randomized trials analyzing the effect of tai chi on the incidence of falls or the time until an elderly person first has a fall. All studies compared tai chi to usual care or other treatments like physical therapy, stretching or exercise. The analysis, in the Journal of the American Geriatric Society, found that tai chi reduced the incidence of falls by 43 percent in those followed for less than a year and by 13 percent in those followed longer. There was no effect of tai chi on time to first fall, and there was some weak evidence that the practice reduced the number of falls that resulted in injury. Falls are a le...

Disney is no longer minting money. At least one kind -- the company recently announced that it will no longer print and sell its beloved currency, Disney Dollars. The bills, which feature iconic Disney (DIS) characters and are signed by treasurer Scrooge McDuck, are worth real U.S. dollars. They're like gift certificates and can still be used at Disney theme parks, resorts, hotels, restaurants and stores. But for many Disney die-hards, they're also collectibles Typically Mickey Mouse was on the $1, Goofy was on the $5 and Minnie Mouse was on the $10. The bills also featured princesses like Cinderella and Sleeping Beauty, villains like Cruella de Vil and Captain Hook; and characters like Dumbo, Simba, the 101 Dalmations and even Lilo from "Lilo and Stitch." Disney stopped selling the bills on May 14, but many are listed on eBay (EBAY). A special edition $50 bill from 2005 that marked Disneyland's 50th anniversary just sold for $495 on Wednesday, whic...

In this "green car" competition, the Smart Electric Drive has two big things going for it. The first big thing is that it's all electric. The second big thing is that, actually, it's really little. That makes it easy on energy. The Smart ED gets an amazing 107 MPGe, or Miles Per Gallon Equivalent. That's a measure of how efficiently a car uses power from any source other than gasoline. By comparison, a Tesla Model S, a much bigger, roomier car, gets 89 MPGe. The American Council for an Energy Efficient Economy recently put out its annual list of the "Greenest Cars" and the Smart ED was named number one. The list is based on fuel efficiency and emissions and, yes, the group does admit that, if you live in an area where your electricity comes from coal-powered plants, driving an electric car like this might not be the best thing you could do for the planet. By the way, you won't find the Tesla Mode S in this gallery. Due to its size, which the...

INDIAN India is a land of ancient civilization. India's social, economic, and cultural configurations are the products of a long process of regional expansion. Indian history begins with the birth of the Indus Valley Civilization and the coming of the Aryans. These two phases are usually described as the pre-Vedic and Vedic age. Hinduism arose in the Vedic period. It is the seventh-largest country by area, the second-most populous country with over 1.2 billion people , and the most populous democracy in the world. One More Child This story took place in India. It is about a very rich woman, who was very sad because she had no children of her own. One time she asked a friend, how she could get a child?. Her friend told her, to go to her poor neighbor's house, because there was a lady that had twelve children and don't have enough money to feed them all and maybe she will give one away. The rich woman went with a bag of gold to the poor w...

Andrew McDonald, a student of High Sierra Workshops, took this photo at the falls, amid a sea of photographers. For a few weeks in February if the conditions are just right, for about 10 minutes around sunset, one waterfall in Yosemite National Park looks more like its opposite — a firefall. Visitors who flocked to the California park last week, many with cameras in tow, have not been disappointed by the glowing transformation of Horsetail Fall, which flows from El Capitan. “In the over 20 years I have been photographing the firefall and leading workshops there in Yosemite, I have never seen a more spectacular one,” said Michael Mariant, a photographer from Morro Bay, Calif., who leads teaching trips to Yosemite. The phenomenon occurs if there has been enough snow and rain in the Sierra Mountains to fuel the waterfall, if the skies are clear and if the setting sun strikes the water at an angle that creates the illusion of lava. Mike Gauthier, the park’s chief of staf...
