Researchers at the Scripps Research Institute in Florida got a bunch of mice addicted to meth. (It’s tough to be a mouse in this world.) But when they blocked a process in the brain that helps them form memories, the mice were no longer interested in the drug. “Our goal is to develop a pill that recovering addicts can use to erase memories associated with drugs,” says Courtney Miller, PhD, assistant professor in the Department of Neuroscience at The Scripps Research Institute, and author of the study....

In the study, 39 women between the ages of 18 and 45 were put through a cycling workout that gradually became more intense. The workout ended either when the participant said she’d reached her absolute maximum effort or when her pedaling fell below a certain speed. Next, the women were split into two groups: One group learned ACT techniques for 40 minutes, while the other women spent 40 minutes setting goals for their next workout....

Before department stores and drugstores filled their shelves with so-easy-my-dog-could-use-it brow products, we were all left to the mercy of our tweezers and using a pencil (um, scary!). Now, at-home brows aren’t hard, they’re standard, thanks to Anastasia Soare, brow expert and creator of her Anastasia Beverly Hills line of brow, skincare, and color products and studios. As a native of Romania, Anastasia grew up inspired by classic Greek, Roman, and Byzantine empires....

Cats have all the luck. Because they’ve earned a reputation as difficult to train, we’re willing to make excuses for even the most inexcusable behavior. But just how much should we cat owners put up with? As a no-nonsense vet, I know cats are teachable. Your pet’s bad manners don’t have to drive you bonkers. Here are the three habits you only think can’t be broken—and how to get your cats to believe the change was her idea....

Daily Essentials Kinder cleansers “Over-40 skin tends to be drier,” says Doris J. Day, MD, 43, which is why she recommends a gentle cleanser that will remove dirt and makeup without stripping away natural oils. Day uses the Good Skin Soft Skin Creamy Cleanser—which she helped create—because it contains natural extracts, like aloe and chamomile, that help skin retain moisture for anti-aging. Many dermatologists love Dove Beauty Bar, which is less acidic (hence less drying) than most other soaps....

Like the book title, “a tree grows in Brooklyn,” but not one apple. We had a back yard with a mimosa tree and dirt. I loved that tree and it seemed like the only sliver of nature around us. That’s why I’m like a kid in a candy apply store when I’m surrounded by nature. I was feeling a little sorry for myself this week after hearing some more harsh words about my dad’s health....

For most of us, these feelings come and go. But when sadness persists for more than two weeks and affects your ability to function at work, at home, or in other aspects of your life, you may have what’s known as major, or clinical, depression. According to the National Institute of Mental Health, depression is a serious mental illness that affects about 17 percent of all adults during their lifetime....

A: To a certain extent, it can, though dry brushing has been overhyped. It involves brushing the body with a natural-bristle brush in even, repetitive strokes. Starting at the feet and working upward, each stroke is directed toward the heart, stimulating lymphatic flow and drainage. (See how it’s done in this video.) The technique originated thousands of years ago and was used by Ayurvedic and traditional Chinese healers, who believe that disease is the result of blockages in the body....

Dr. Henry’s lecture started with the basics of fat metabolism, much of which we know all too well: When we overshoot our daily calorie allotment, and don’t burn off the excess by being active, we metabolize extra calories into fat which eventually settles in places all over your body, including deep inside your belly. But what you might not know is that once inside your belly, that fat actually becomes an organ....

Researchers in South Korea performed a gigantic analysis of preexisting studies on fiber intake, examining the diets and health of more than 900,000 people worldwide. Their primary finding was that people who ate a high-fiber diet (an average of 27 grams per day) were 23% less likely to die of any cause than those who ate a low-fiber diet (around 15 grams daily). But the benefits weren’t distributed equally across the board....

For the study, published in the journal Molecular Psychiatry, researchers from the National Institutes of Health (NIH) tracked nearly 1,400 individuals using data from the Baltimore Longitudinal Study of Aging. Of those individuals, 142 ended up with Alzheimer’s. The NIH team examined how the participants’ cognitive abilities changed during the roughly 14-year study period. They found a higher body mass index (BMI) at age 50 correlated with earlier onset of Alzheimer’s....

Yep, you’re one of the 10-15% of the general population that suffer from migraines. But before you pop that painkiller and wait for the storm to pass, know this: a new study discovered how migraines—especially ones with aura—permanently alter the structure of your brain. In a meta-analysis published in Neurology, researchers found that migraine with aura increases your risk of white matter, infarct-like brain lesions by 68% and a 44% increase in risk for change in brain volume—the increase or decrease in brain tissue....

I ordered an emergency angiogram, expecting to find a blocked artery. But her vessels were completely clear. And then something strange happened: Within hours, her symptoms disappeared. She was released from the hospital, and she’s been healthy ever since. As it turns out, my patient had a classic case of broken heart syndrome, a recently discovered condition that almost exclusively affects middle-aged and elderly women (average age: 60). As the name suggests, BHS usually stems from emotional rather than physical causes and has the same symptoms as a real heart attack....

Jill’s answer: I hear this all the time from clients: “I’m scared of carbs!” I get it. The low-carb diets of the ’90s and early 2000s have us scared that we are getting fatter by the gram and we’ll develop diabetes to boot. The truth is, carbs aren’t evil—they’re individual. First, it is important to understand the role of carbs as they relate to how we look and feel. Carbs help build muscle, and they can help sustain balanced energy (i....

The primary law responsible for ensuring chemicals are safe—the Toxic Substances Control Act (TSCA)—was passed in 1976 and has never been updated. The law is so weak, in fact, that the US Environmental Protection Agency (EPA) has only been able to require testing on less than 2% of the more than 80,000 chemicals that have been on the market at some point since TSCA was adopted. The Senate Environment and Public Works Committee is slated to vote Wednesday on a piece of legislation—the Safe Chemicals Act of 2011—that would toughen federal chemical regulation....

So you think you can’t dance? We’re here to tell you: There’s no right or wrong way to shake that booty—and doing it might very well be the health boost you need, finds new research. Swedish researchers, writing in the Archives of Pediatrics & Adolescent Medicine, studied 112 teenage girls who were struggling with problems including neck and back pain, stress, anxiety, and depression. Half of the girls attended weekly dance classes, while the other half didn’t....

Got…diet milk? You might be drinking something akin to that soon, now that two prominent dairy organizations have asked the Food and Drug Administration (FDA) for permission to include artificial sweeteners in milk. The original petition, filed in 2009 by the International Dairy Foods Association and the National Milk Producers Federation, sought to use these ingredients in milk products without specific mention on the front of packages (the sweeteners would be included on ingredient labels)....

Thankfully, researchers have just simplified the decision: Do exercises that target the body part you deem the most important first. This maximizes your workout potential, say researchers; they found that as a workout progressed, fatigue took over and diminishing the benefit of later exercises. “The exercise that stimulates the most important muscle group should be placed at the beginning of the session with the goal of improving the training volume,” said Gabriel Paz, co-author of the study published in the Brazilian Journal of Physical Activity and Health....
