  • A Man's Walking Speed Might Tell You If He's Interested, Study Says

    Your walking pace might say more about your relationship than you think.Our walking speeds are dictated by more than whether we're rushing to an appointment or taking a leisurely stroll. Rather, we subconsciously tailor our pace according to our physical features, such as how long our legs are and how much we weigh, in order to minimize energy expenditure. For men, hitting that sweet spot generally means walking faster than women.

    But what happens when men and women walk together? In order not to lose each other on the street, someone would have to either slow down or speed up their natural pace. An October 2013 study finds that the adjustment says more about love than mechanics.

    Researchers recruited 22 guys and gals of various weights and heights. Some of them were romantically involved, others were just friends. They paired the participants up with either love interests, same-sex friends or different-sex friends, and asked them to casually walk around a track while their speeds were

  • Scientific Breakthrough: Cure for Hair Loss Could Be Here Soon

    The fix for thinning hair could be on the horizon!Hair loss may no longer be a life sentence.

    The breakthrough comes from Columbia University Medical Center (CUMC), where researchers successfully grew human hair by mimicking a cell behavior that is thought to give rodents perpetual hair growth-a method that is particularly exciting for women experiencing hair loss.

    The secret lies in dermal papillae cells, which help form and nourish hair follicles. When human cells of this kind are transplanted, they revert to basic skin cells and lose the ability to birth new follicles. But when the same is done to rodent dermal papillae cells, they form clumps that scientists think allow the papillae to interact and release signals that reprogram skin to grow new hair follicles.

    "This suggested that if we cultured human papillae in such a way as to encourage them to aggregate the way rodent cells do spontaneously, it could create the conditions needed to induce hair growth in human skin," says first author

  • 9 Diet-Friendly Halloween Treats Under 250 Calories

    If Halloween isn't a time to indulge, we don't know what is! But that doesn't mean you should get spooked by the thought of a candy-filled, calorie-laden celebration, notes Keri Glassman, nutritionist and author of "The New You (and Improved!) Diet."

    "Whatever snack you do choose to indulge in, make sure you eat it slowly, savoring every delicious bite," advises Glassman. "That will help you to feel satisfied without going overboard." Speaking of overboard, keep in mind that candy marked "king size" is a red flag for a scary portion of calories, sugar and fat. Instead, opt for the smaller "fun size" treat to satisfy your sweet tooth while controlling the portion size.

    To help you-and your waistline-enjoy Halloween without derailing your diet, here are nine not-so-scary treats that are all under 250 calories.

  • Exercise in a Pill: The Drug of the Future?

    Would you pop one instead of working out?That post-work out feeling of accomplishment and stress-free bliss is not the only neurological gift exercise imparts. Researchers know that exercise-especially of the endurance variety-boosts our overall brain health and function, including improving learning and memory and slowing cognitive decline in old age. How exercise promotes these mental perks, however, remains poorly understood.

    In pursuit of a formula for exercise's elixir, neuroscientists and cell biologists from Harvard Medical School and the University of Michigan Medical Center decided to focus on one suspect protein, FNDC5, which is secreted from muscles during exercise. To see what the protein does, they monitored exercise-loving mice that spent most of their time running on a wheel for 30 days. When the mice began producing FNDC5, they observed, it kicked off the rise of another protein, BDNF, in the brain. BDNF helps to form new connections between nerves

  • 5 Foods That'll Give You Healthier Genes

    What you put into your body matters even more than you might think.Starting with your next meal, you can take some control today in minimizing your risk of cancer just by paying attention to the food you eat.

    A phenomenon called epigenetics is at play here. Epigenetics is the study of changes in gene expression, caused by mechanisms other than changes in our underlying DNA sequences. In English, that means that each of us has DNA in all of our genes that we inherit from our parents. We get what we get. But we can change some of how these genes work by manipulating other outside factors-factors such as food! Seriously, what you eat can affect your genes. That's epigenetics.

    Research, both in the laboratory and in the clinical setting, has shown how foods can affect gene expression. For example, in the lab, Nobuyuki Kikuno et al* have shown that phytoestrogens such as genistein (a chemical in soy) may be chemoprotective in prostate cancer (that means they protect against it). Prostate cancer is very similar

  • The Scary Breast Fact Every New Mom Needs to Know

    Share this information with all the new moms in your life!When you're pregnant you pay a lot of attention to your breasts. First they get bigger (and bigger…and bigger?!). Then, they start producing milk. And then you have a baby and spend most of each day feeding, pumping or tending to your sore nipples. But even with all this breast-centric behavior, you might be missing the most important thing of all: signs of breast cancer.

    The risk for breast cancer increases immediately after every full-term pregnancy and stays higher for the next 10 years. According to research funded by the Avon Foundation for Women, the rates of pregnancy-associated breast cancer (PABC) peak between 5 and 7 years after giving birth. During this time, the risk of dying from breast cancer increases 2.5-fold. And this isn't just for your first baby, but for every child after that, as well.

    The reason is that the same hormones that prepare your breasts for lactation can fuel the growth of cancerous cells.

  • The Easiest Way to Make Friends

    You'll be surprised at the relationships you can cultivate when you end the one with your phone.It's no secret that I'm totally reliant on my electronic devices. In fact, I wrote an article for YouBeauty last year about an experiment to nix social media for a week. I nailed the task, but sunk back into my junkie-like addictions within a month's time.

    The truth is, technology makes me feel secure. I like knowing what's going on in my friends' lives, keeping up with old classmates and feeling as if I have more friends by using social media. (The numbers say so, right?)

    Being the parent of school-age children, fall break gives my wife and I time to come up for air after eight weeks of homework, practices, games and parent-teacher conferences. As I walk my dog around the neighborhood, I'm beginning to see decorations for Halloween, which means future parties, costumes and candy.

    The holiday season has begun. How did it get here so fast? I don't know if I'm ready for it. If we aren't careful, any positive efforts we've made to improve or maintain our health may go by the wayside in a heartbeat.

  • Want to Be Taken Seriously? Stop Sweating

    You might have a good poker face... but your scent could be sending different signals.It's a classic cop-drama trope. A bead of sweat drips down the brow of a suspect under questioning, the telltale sign of a lie about to be exposed. Perspiring betrays discomfort. Indeed, nothing says nervous like a shirt soaked-through with sweat. But even if you can keep the wetness under control-or at least under a couple layers of clothing-you may still be sending out a chemical distress signal that others can detect.

    An October 2013 study in the journal PLOS ONE found that when people give off the smell of sweat, it makes others question their confidence and abilities. In the experiment, participants were shown video clips of women doing "neutral" activities, such as doing work at the office, hanging out at home and taking care of their kids. Meanwhile, researchers pumped three types of sweat fumes into their noses: exercise sweat, stress sweat and stress sweat treated with Secret Clinical Strength. (The study was funded but not conducted
