Spurned Pluto is changing its looks, donning more rouge in its complexion and altering its iceball surface here and there.
Color astronomers surprised.
Newly released Hubble Space Telescope photos show the distant one-time planet — demoted to "dwarf planet" status in 2006 — is changing color and its ice sheets are shifting.
The photos, released by NASA Thursday, paint a Pluto that is significantly redder than it had been for the past several decades. To the layman, it has a yellow-orange hue, but astronomers say it has about 20 percent more red than it used to have.
The pictures show icy frozen nitrogen on Pluto's surface growing and shrinking, brightening in the north and darkening in the south. Astronomers say Pluto's surface is changing more than the surfaces of other bodies in the solar system. That's unexpected because a season lasts 120 years in some regions of Pluto.
"It's a little bit of a surprise to see these changes happening so big and so fast," said astronomer Marc Buie of the Southwest Research Institute in Boulder, Colo. "This is unprecedented."
From 1954 to 2000, Pluto didn't change in color when it was photographed from Earth. But after that, it did. The red levels increased by 20 percent, maybe up to 30 percent, and stabilized from about 2000 to 2002, Buie said. It's not as red as Mars, however, Buie said.
Buie said he can explain the redness, but not why it changed so dramatically and so recently. The planet has a lot of methane, which contains carbon and hydrogen atoms. The hydrogen gets stripped off by solar winds and other factors, leaving carbon-rich areas on the surface, which tend to be red and dark.
The Hubble photos were taken in 2002 and the analysis took a few years. But why Pluto changed so quickly was such a mystery that Buie held off for years on announcing what he had found, worried that he might be wrong. However, since Pluto's moon Charon hadn't changed color in the same telescope images, he decided the Pluto findings weren't an instrument mistake.
His analysis also found that nitrogen ice was shifting in size and density in surprising ways. It's horribly cold on Pluto with, paradoxically, the bright spots being the coldest at about -382 degrees Fahrenheit. Astronomers are still arguing about the temperatures of the warm dark spots, which Buie believes may be 30 degrees warmer than the darker areas.
Part of the difficulty in figuring out what is going on with Pluto is that it takes the dwarf planet 248 years to circle the sun, so astronomers don't know what conditions are like when it's is farthest from the sun. The last time Pluto was at its farthest point was in 1870, which was decades before Pluto was discovered. Unlike Earth, Pluto's four seasons aren't equal lengths of time.
Buie's explanation makes sense, said retired NASA astronomer Stephen Maran, co-author of a book on Pluto. "Pluto is interesting and poorly understood, whether it qualifies as a planet or not," he said.
back pain brought on by the wear and tear of living. It seems simple to pop a pill for the pain, but why not avoid the side effects by trying natural possibilities first? You can turn to natural healing practices and herbs to alleviate back pain.
The Chinese medical perspective
According to Chinese medicine, the skeletal structure, bones, and lower back are part of the kidney network. Kidney energy tends to diminish as we age, more rapidly with unhealthy diet, excessive strain, and youthful indiscretions such as drug and alcohol use. Weakness in the kidney network results in symptoms of lower back pain, as well as general weakness, fatigue, and other signs of premature aging. Replenishing kidney energy is a slow and difficult process; that is why it is essential to preserve kidney energy. Fortunately, through qigong exercises, herbs, proper diet and lifestyle, you can slow down its depletion and even regenerate certain aspects of kidney energy, and in the process, ease some of your back pain. Try these tips!
1. Eucommia for your aching back
Eucommia is a traditional ingredient in herbal formulas for back and joint pain and helps to strengthen your bones, tendons, and ligaments. Western studies with rats have discovered that both the leaves and the bark of eucommia contain a compound that encourages the development of collagen, an important part of connective tissues like skin, tendons, and ligaments. A typical dosage is 350 mg twice a day. You can also try the traditional Chinese Arthritis/Joint formula, which includes eucommia and other herbs that support a strong back.
2. Press here for relief
Lower back pain is one of the most common problems that we treat at the Tao of Wellness. We use acupuncture and bodywork to reduce pain, which has proven quite effective. Like acupuncture, acupressure is the art of acupuncture without needles, where you use your own fingers to stimulate a specific acupoint. The combination of the following two acupoints is good for strengthening the kidneys and alleviating back pain:
• Find the acupoint: Forceful Torrent (Ki-3), which is in the depression between the inner anklebone and the Achilles tendon of the right foot. Apply steady pressure with your right thumb until you feel soreness. Hold for 3 minutes. Repeat on the left foot.
• Find the acupoint: Supporting the Core. It's in the middle of the popliteal crease behind the knee of the right leg. Apply pressure with your right middle finger until you feel soreness. Hold for 3 minutes. Repeat on your left leg.
You can also massage the parts or your back that are in pain. Tonic oil, which consists of oils of camphor, peppermint, eucalyptus, fennel, and wintergreen, can be massaged into your back for relief from minor aches and pains. For a traditional blend of tonic oil in a pure sesame oil base,
3. Tasty treats for back pain
Make a delicious anti-inflammatory cocktail by mixing equal parts of unsweetened black cherry juice with dark grape juice and drink 3 to 6 glasses a day until the pain has eased. Also, feature more pineapple in your diet. Pineapple contains an enzyme called bromelain, which is a natural anti-inflammatory that helps with back pain, as well as muscle and joint pain.
4. Exercise can ease your back
Most back pain is caused by the wear and tear of living, which over time weakens our skeletal structure, in the form of bone loss or a displaced disk. Research conclusively shows that exercise early in life builds bone mass and strengthens the skeletal structure, helping to prevent injury down the road. The good news is that if you are advancing in age, regular exercise can slow the progress of degenerative bone disorders. Generally for a healthy back, I recommend a combination of exercises: a 30-minute daily walk, moderate weight training to strengthen muscles and bones, and tai chi or qigong to build endurance and flexibility. A good form to choose is Dao-In qigong, which is gentle on the body and great for loosening up the back. . During acute back pain, exercise may be difficult or too painful. Until you are mobile, bed rest is the best.
I hope you have found some natural ways to alleviate your back pain! I invite you to visit often and share your own personal health and longevity tips with me.
May you live long, live strong, and live happy!

True story: A good friend, someone I consider pretty savvy about health, diet, and wellness, recently e-mailed me and asked if eating celery will help you lose weight (something about it being a negative-calorie food). As far as rumors go, this one was pretty tame, but in some cases misinformation can be downright dangerous. Plus, whatever their origin, health “hearsays” like these can cause unnecessary anxiety and distract you from habits that truly deserve your time and energy. Here, eight common watercooler myths, and what’s true, what’s misunderstood, and what’s just downright wrong.
1.) Baby carrots are preserved with bleach
Not exactly... and there's no reason to stop eating them, says Randy Worobo, PhD, an associate professor of food microbiology at Cornell University. Baby carrots are rinsed (not preserved) in a chlorine wash, recommended by the FDA, to kill bacteria like salmonella and E. coli, which cause foodborne illness. Most precut produce, including frozen veggies and fruit salad, is washed with this or a similar sanitizer.
2.) Working out on an empty stomach burns more fat
It does, but don't expect any fat-melting miracles. When you exercise, your body burns calories from both fat and carbohydrates. Recent studies show that working out on an empty stomach might burn a few more fat calories since you don’t have as many carb calories to spare, but overall calorie burn is about the same. And, based on research so far, that's what really counts when it comes to fitting into a smaller size.

3.) Eating too much sugar causes diabetes
Not in the same smoking-gun way that cigarettes cause cancer, but research shows that sugar may play a part—and it's smart to limit your intake. First and foremost, being overweight does increase your risk of developing type 2 diabetes, and consuming too much sugar can contribute to weight gain. Still, some emerging research suggests that excess sugar intake can increase diabetes risk regardless of weight. A landmark JAMA study found that women nearly doubled their diabetes risk when they increased the number of sugar-added drinks they consumed from one or fewer a week to one or more per day over a 4-year period.

4.) Does Listerine mouthwash help keep mosquitoes away?
No. Although Internet postings swear it's true, scientists beg to differ. Our research has found that people who sprayed Listerine on their arms were just as likely to be bitten as those who didn't use any repellent, says Grayson Brown, PhD, a University of Kentucky public health entomologist. The myth persists thanks to a strong placebo effect and because Listerine has eucalyptol, an ingredient found in some botanical bug sprays. But the concentration in mouthwash (less than 1%) is too low to have an impact.

5.) Spicy foods boost metabolism
I wish! Your metabolic rate is determined by your gender, height, present weight/body composition, and age. These factors determine the amount of calories the body will burn to maintain the basic functions of life that occur even when we sleep—the energy used by the heart, brain, lungs, intestines, etc. Eating spicy foods cannot significantly increase metabolic rate and help you burn more calories at rest. Although your body temperature may temporarily rise and your heart may beat a bit faster after eating "hot" foods, over the long term spices will not make any changes in the rate of metabolism.

6.) Liquid eyeliner causes sinus infections
This rumor presumes that eyeliner is able to drain into the sinuses, get trapped, and cause an infection, but that's not possible, says Richard Rosenfeld, MD, chairman of otolaryngology at Long Island College Hospital. Your natural tearing process can funnel bits of makeup into the tear ducts, but they drain into the nose and out the nostrils. If you develop eye irritation and sinus symptoms after wearing eyeliner, you probably had an allergic reaction.

7.) It’s safe to follow the 5-second rule for dropped food
It's probably not even safe to follow a 1-second rule: The transfer of bacteria from a contaminated surface to food is almost instantaneous—or, at the very least, quicker than your reflexes. In one study, Clemson University food scientist Paul Dawson, PhD, and students contaminated several surfaces (ceramic tile, wood flooring, and carpet) with salmonella. They then dropped pieces of bologna and slices of bread on the surfaces for as little as 5 seconds and as long as 60 seconds. After just 5 seconds, both food types had already picked up as many as 1,800 bacteria (more bad bugs adhered to the moisture-rich bologna than the bread); after a full minute, it was up to 10 times that amount.

8.) Can cracking your knuckles cause arthritis?
Nope. If you're suffering from osteoarthritis in your hands, it certainly has nothing to do with this nervous tic. One study at the former Mount Carmel Mercy Hospital in Detroit compared 74 people (ages 45 and older) who had been chronic knuckle crackers for decades with 226 who always left their hands alone; researchers found no difference in the incidence of osteoarthritis between the two groups. But there are reasons to stop this annoying habit: The same study found knuckle crackers to be far more likely to have weaker grip strength and greater hand swelling, both of which can limit dexterity. As for osteoarthritis, that's more likely due to genetics and increasing age
