Most parents yell at their kids at some point. It often feels like the last option for getting children to pay attention and shape up.
But harsh verbal discipline may backfire. Teenagers act worse if they're yelled at, a study finds.
Researchers asked parents of 13-year-olds in the Philadelphia area how often in the past year they'd yelled, cursed or called the kid "dumb or lazy or some other word like that" after he or she had done something wrong.
A brain that trains can stay in the fast lane. That's the message of a study showing that playing a brain training video game for a month can rejuvenate the multitasking abilities of people in their 60s, 70s and 80s.
"After training, they improved their multitasking beyond the level of 20-year-olds," says Adam Gazzaley, one of the study's authors and a brain scientist at the University of California, San Francisco.
If you're on Medicare and you're in the hospital for a few days, you may think you're an inpatient. The hospital may have other ideas. Increasingly, hospitals are placing older patients on "observation status." They may be there for days, but technically they're still outpatients.
This is a big deal for someone on Medicare because follow-up treatment in a nursing home isn't covered unless someone has been an inpatient for at least three days. That's leaving some seniors on the hook for thousands of dollars in nursing home bills.
Obstetricians perform more cesarean sections when there are financial incentives to do so, according to a new study that explores links between economic incentives and medical decision-making during childbirth.
The good news: Cigarette sales are down by about a third over the past decade. Not so for little cigars and cigarillos. Their sales more than doubled over the same time period, in large part owing to the growing popularity of these little cigars among teenagers and 20-somethings.
The appeal among young people has lots to do with the large variety of candylike flavors in the little cigars, according to Jennifer Cantrell, director of research and evaluation at the anti-tobacco Legacy Foundation.

Biologist Bernd Heinrich was in Zimbabwe, in the field, eyes down, looking for beetles, when for no particular reason he looked up and saw ... well, at first he wasn't sure what it was, so he stepped closer, leaned in, and there, painted on the underside of large protruding rock, were five human figures "running in one direction, from left to right across the rock face." They weren't very detailed, just "small, sticklike human figures in clear running stride" painted by a Bushman, two, maybe three thousand years ago.
Bullied children and kids who bully others have more health problems when they grow up than kids who aren't part of the bullying cycle, a study finds. They're also more likely to have financial problems, including difficulty keeping a job.
The findings run counter to a still-widespread notion that bullying is a childhood rite of passage with little lasting harm, the researchers say.

For all the benefits of exercise and teamwork to the heart and head, high school athletes still lead the nation in athletics-related deaths. And it doesn't have to be that way, sports medicine specialists say.
