Does this dog know what your feeling?Using MRI technology, scientists at Emory University set out to determine how dogs' brains work, and they discovered that dogs experience emotions in a way comparable to humans.
Or, as researcher Gregory Berns concluded, "Dogs are people too."
For two years Berns and his colleagues have trained dogs to enter an MRI scanner while awake and unrestrained. Typically, animals are anesthetized so they won't move during a scan, but you can't study brain functions like perception and emotion when an animal is asleep.
Another reason Berns chose not to anesthetize his canine participants is because he says wanted to treat the dogs like people.
All the dogs in the study have consent forms signed by their owners, and only positive training methods are used to prepare the animals for the MRI.
Berns' own dog, Callie, was the first dog to have her brain scanned. With the help of a dog trainer, Berns taught Callie to enter an MRI simulator he'd built in his home.
Callie learned to enter the

This dog loves to eat grass. But why?by Morieka Johnson, Mother Nature NetworkRead More »from Why Do Dogs Eat Grass?
No walk around the neighborhood is complete without my dog Lulu eating grass. Even on a full stomach, she likes to hunt for the perfect blades and chew away. Left unattended, I'm sure she could mow down a small lawn. Since lawns today have any number of number of chemicals, I decided to check with an expert about whether her grass-eating habits do more harm than good.
Dr. Jennifer Monroe of Eagles Landing Veterinary Hospital in Georgia explains the most common reasons that dogs eat grass.
It's yummy: Monroe says that it is normal for dogs to chew on the green stuff. Some pooches even develop preferences that range from fresh leaves to drier weeds or even a particular species of grass. What they cannot discern is whether grass has been chemically treated. Use caution when walking on a neighbor's lawn and stick with greener products in your own yard. Monroe recommends nontoxic treatment options, and MNN has more than a few easy, organic lawn
From food to flowers, why are today's kids more allergic to things?by Sami Grover, Mother Nature NetworkRead More »from Why Are so Many Kids Allergic These Days?
Earlier this year, the Centers for Disease Control and Prevention (CDC) published a major study on children and allergies. The results were astounding. Among other things, the government survey suggested: 1 in 20 children have food allergies (up 50 percent from the 1990s). 1 in 8 have skin allergies or eczema (that number is up 69 percent). There has been no increase in hay fever or other respiratory allergies In some ways, these numbers are no surprise.
Allergies on the rise?
Most of us with young children know families with food or skin allergies. To protect those children, it is now common practice in many childcare and school settings to ban or severely restrict potential allergens like tree nuts from all children's lunches.
But we have to be cautious. It's hard to tell how much allergies have actually increased, and how much the reporting of allergies has increased due to greater awareness and/or a better understanding of the science.

Brushing your teeth after eating may not be a good ideaWhether you are a diligent brusher of the teeth right after eating, or if you're like the rest of us and feel a tinge of shame for not doing so, you may be interested in knowing this: at least one study has shown that the practice is not in the best interest of your pearly whites.Read More »from Surprising Advice from Dentist: Don't Brush Teeth After You Eat
While some professional opinions vary, a number of top teeth docs agree with the findings. The basic problem is that the sugar in foods is metabolized by the bacteria or plaque on enamel, producing acids that lead to gum disease and cavities.
Common sense suggests that brushing the food particles away as quickly as possible would reduce the problems; but such is not the case.
Dentist Jeffrey M. Cole, former president of the Academy of General Dentistry, a dental advocacy group, told the Wall Street Journal, "What we found is that much of the cariogenic substances, those things that cause cavities, are not only sugar-containing, but they are very acidic themselves."

How safe are headphones?Let's talk a little bit about how headphones came to be in the first place. Headphones were developed in 1910 by Nathaniel Baldwin in Utah. According to Smithsonian magazine, he sold the first pair of headphones to the U.S. Navy, who found them to be a vast improvement over the mechanism that Naval radio operators were using. Fast forward to just after World War II: John Koss, jazz musician and the founder of Koss Corp., developed the first headphones designed specifically for music, closely mimicking the sounds of a concert-filled hall and quickly attracting music-lovers.Read More »from Are Headphones Bad for Your Hearing?
For about 30 years, headphones looked the same until Sony came up with little earphones that fit in your ear to accompany its Walkman. They didn't reach their peak of popularity until 2001 when Apple and Steve Jobs introduced the iPod and shipped each one with white earbuds - instantly recognizable in the ears of millions of Apple-using teens and adults today.
Headphones have always been a danger to our hearing, if
Training a puppy doesn't have to be a drainAdding a puppy to a household can be fun and hectic, especially if you already have a dog. Anyone taking the plunge - including the Obamas, who recently welcomed Sunny, a Portuguese water dog, to their pack - will benefit from some training. Dog trainer Sarah Wilson, author of "My Smart Puppy," offers tips for training a puppy and setting a course for many happy years together.Read More »from This is the Best Way to Train a Puppy
Begin training on Day One
Wilson describes puppies as "little learning sponges," so help them acclimate to bath time, car rides and daily walks as soon as possible. In addition to her own 9-year-old pooch, Wilson cares for a 10-week-old poodle-golden retriever mix named Button that already has learned the ropes. Button knows the "sit" and "down" command, she comes when called and doesn't mind having her nails done. Fun, short sessions keep Button engaged. Treats also help set a positive tone.
"Her tail is wagging a mile a minute, but we are learning to communicate and forging a foundation," Wilson says.
The panda cam at the National Zoo has gone dark. Oh no!The government shutdown doesn't only affect the American people, but also the nation's animals. Take a look at how the government's failure to pass a spending plan will change the daily routines of animals in zoos, parks and wildlife refuges.Read More »from How the Government Shutdown Affects Animals
The National Zoo's beloved panda cam - as well as its dozen other animal Web cameras, including one for the newly arrived Sumatran tiger cubs - has gone dark. The zoo is now closed to visitors, but the shutdown won't affect care of the animals. Veterinarians and all staff involved in the feeding and cleaning of animals are considered essential employees.

Washington's budget impasse means 800,000 Americans won't be getting paid, but ivy-munching goats are also out of work. On Friday, Larry Cihanek removed his Nubian goats from the Gateway National Recreation Area at Sandy Hook, N.J., and from Fort Wadsworth in Staten Island, N.Y., in anticipation of the park closings. The herds had been helping eradicate poison ivy from
What does your hair say about your health?Most of us view our hair as separate from the rest of our body, but like our nails, hair is an extension (pun intended) of our body that can give us clues as to our overall health. Herein, four hair signs that something may be amiss.Read More »from 4 Things Your Hair Says About Your Health
If you once had thick, lustrous hair that turned fine and limp, first look to see what you've been doing to your hair lately. Have you been swimming a lot in chlorinated water? Did you dye your hair recently? These things, among others, can cause your hair to lose its luster. But limp, dry hair may also be a sign of hypothyroidism, or an underactive thyroid, in which your thyroid gland doesn't produce enough hormones, causing your metabolism to slow down. Other signs of hypothyroidism can be sudden weight gain, unexplained fatigue, and being cold all the time. If you suspect hypothyroidism to be the culprit, talk to your doctor about testing your thyroid levels. If you do have an underactive thyroid, you can often take medication to supplement your

Fiber helps feed beneficial gut bacteria. It speeds up digestion. It can change how other nutrients and chemicals are absorbed by the body. And some types of fiber absorb water in the digestive tract and help avoid constipation.
In fact, eating enough fiber is absolutely crucial to maintaining a healthy digestive system. And maintaining a healthy digestive system is central to overall well-being.
The average healthy male under the age of 50 is supposed to eat as much as 38 grams of fiber a day - the equivalent of 5 full portions of kidney beans - and for women, the figure is 25 grams.
But there's more to think about than just how much fiber you are getting, namely how many different types. Because the term "dietary fiber" covers a wide range of different plant-based substances that your body needs to function healthily, I recommend to my clients that they eat a broad mix of different high fiber foods.

Chicks dig the Adorable Care ActThe Affordable Care Act has had its share of critics, but kittens, sloths and baby bunnies aren't among them.Read More »from Cute Animals Launch 'Adorable Care Act'
In fact, America's cutest critters are such fans of Obamacare that they launched their own social media campaign to promote it.
The "Adorable Care Act," which has a presence on Twitter, Facebook and Tumblr, recently gained national attention when the White House's official Twitter account retweeted one of its images.
The photo of a mouse sitting on a tiny swing read, "I can rest easy knowing that lifetime caps on health coverage have been eliminated! Thanks, Adorable Care Act!"
The Adorable Care Act social media campaign features several images of puppies, ponies and other baby animals alongside supportive messages of Obamacare, but the Obama administration insists it's not behind the precious political move.
