15 Ways to Be More Attractive, According to Science

OK, here's the truth: Not all men are born with good looks and charm. In fact, lots of guys are born with neither. But does that mean you're fated to spend your life alone in your apartment, with only Netflix and your dog to keep you company? Absolutely not.

The truth is that while looks do matter to men and women alike, it's far from the most important thing when it comes to finding a partner. The science of sexual attraction is a complex one that involves multiple different factors, from the way you smell to the shape of your jaw to even the color of the shirt you're wearing.

Why You Should Ejaculate At Least 21 Times This Month, According to Science

The key to good prostate health might be in your own hands: Ejaculating frequently may reduce your risk of prostate cancer, finds new research from the Boston University of Public Health.

The study looked at how ejaculation frequency affected prostate cancer risk over the course of 18 years.

It found that men ages 20 to 29 who ejaculated 21 times or more each month were 19 percent less likely to be diagnosed with prostate cancer than those who ejaculated less often, between 4 and 7 times per month.

Science Just Discovered a Strange Link Between Naps and Diabetes

Pull your head out from under the covers: Taking long naps might increase your risk of heart problems and diabetes, a new meta-analysis presented at the American College of Cardiology’s (ACC) Annual Scientific Session suggests.

After analyzing data on more than 300,000 people from 21 different studies, the researchers concluded that people who napped more than 60 minutes a day—and who reported high levels of daytime fatigue—were about 50 percent more likely to develop diabetes than those who napped for less than an hour a day.

The Science behind Why You’re a Picky Eater

You call your palate “selective.” Your friends call you a picky eater. But researchers have discovered that there are actual scientific reasons that may explain why the short list of foods you eat mostly comprises of chicken fingers, buttered noodles, grilled cheese, and pizzas.

“Like many behaviors, it appears to be the result of a complex interaction between your genes and the environment,” says Marcia Pelchat, Ph.D., a researcher at Monell Chemical Sense Center in Philadelphia who focuses on food preferences.

Let’s start with genetics. Variants of a gene associated with taste, called TAS2R38, determine how strongly you taste bitter flavors, like coffee or kale, researchers say. And if you perceive that broccoli, for instance, as being unbelievably bitter, you may shun it.
