High school students who acknowledge texting while driving are more likely to engage in other risky behaviors, such as riding with a driver who has been drinking alcohol; not wearing a seat belt; or drinking and driving themselves, according to a new study.

“This suggests there is a subgroup of students who may place themselves, their passengers and others on the road at elevated risk for a crash-related injury or fatality by engaging in multiple risky MV (motor vehicle) behaviors,” wrote the authors of the study, published Monday in the journal Pediatrics.

High-tech tools for STDs

Ramin Bastani believed he was about to get lucky. A woman he’d met earlier that night was making her way toward his bedroom.

Suddenly, he hesitated. It didn’t go unnoticed.

“What’s your deal? Are you gay?” the woman asked.

No. He wasn’t gay.

“What is it?” she wondered. “Oh my gosh! Do you have an STD?”

No, it wasn’t that either.

Alarmed, she stepped away from him.

“Oh my God! Yes, you do. You have an STD,” he recalls her saying emphatically.

Bastani confessed what was bothering him — he barely knew this woman.

“No,” he told her. “I’m afraid you might.”

She slapped him across the face and walked out of the room.

It’s the kind of awkward moment a lot of men might prefer to forget, but for Bastani it was the impetus for starting his company, Qpid.me, a free website that lets users text and share their verified sexually transmitted disease results with potential partners.

When faced with a challenge, whether you deny the problems it poses or dive in to solve them in a positive way may determine how much anxiety you feel overall.

According to the National Institute of Mental Health, about 40 million Americans aged 18 and older are diagnosed with an anxiety disorder every year. To dig deeper into who may be at greatest risk, investigators from the University of Illinois at Urbana-Champaign surveyed 179 healthy men and women and asked them how they dealt with their emotions and how their answers correlated with their level of anxiety in a variety of settings.

Breaking a sweat does more for your body than just trim your waistline. Exercise may lower a woman’s risk for breast cancer and researchers are finding out why.

Scientists from the University of Minnesota in St. Paul conducted a study of 391 inactive, healthy, premenopausal women whom they split into two groups. They found that the 179 women in the intervention group, who received 30 minutes of moderate-to-vigorous exercise five times a week for over 16 weeks, showed changes in their estrogen metabolism that could explain the anti-cancer benefits of working out.

New Test Distinguishes Physical From Emotional Pain in Brain for First Time

By
May 7th, 2013

New research suggests physical pain may have a distinct brain “signature” that distinguishes it from emotional hurt.

In the brain, the pain from broken leg and the anguish of a broken heart share much of same circuitry. But the latest evidence points to distinct ways that the brain processes each type of pain and could lead to a greater understanding of how to detect and treat them.

“Of all the things I’ve observed in the brain, nothing is more similar to physical pain than social pain,” says lead author Tor Wager, associate professor of neuroscience at the University of Colorado in Boulder, “What we’ve done in the latest paper is to develop something that predicts physical pain at a much more fine-grained level.”
