Blood cells can generate stem cells, studies show

Researchers have successfully reprogrammed human blood cells into embryonic-like stem cells according to three news studies. Experts say this has the potential for changing the course of stem cell research.

Three years ago, researchers in Japan and the United States announced they had taken a simple skin cell – inserted four viruses, which reprogrammed the blood cells to an embryonic stem-cell like state and a source of embryonic-like stems cells. These cells are called induced pluripotent stem cells (IPS cells) and are believed to have the ability to turn into any cell in the body, just like embryonic stem cells, but without the controversy of destroying an embryo, which happens when embryonic stem cells are removed from the embryo.

"I'm constantly trying to tell them I understand your struggle...you can make it, you can change your life," says Saballett. "So if I'm asking young people to be healthy, live right, work out, do their thing, and I'm not doing it, there's something wrong there."

Swim lessons only one part of water safety

Cooking out, swimming, and watching fireworks is how many Americans will celebrate this July 4th holiday weekend. While celebrating outside by the water can be fun, it can also be dangerous for young children who don't know how to swim to be near water.

According to the National Drowning Prevention Alliance, drowning is the second leading cause of unintentional death among children ages 1 to 4 years old and children 10 to 14 years. Children 4 and under actually have the highest drowning death rate in the United States and the majority of child drownings occur in backyard pools & spas, according to Safe Kids USA. Just this week, former NFL quarterback Randall Cunningham's 2-year-old son drowned in his parents' pool spa, a spokeswoman for the Las Vegas, Nevada, Police Department told CNN Wednesday.

Report: Smoking rate within LGBT community nearly double general population

A startling disparity exists between the smoking rate in the lesbian, gay, bisexual and transgender community compared to the general population, concludes a new report released by the American Lung Association.

Researchers combed through more than 40 separate analyses to determine that lesbian, gay, bisexual, and transgender people are more likely to use tobacco. Specifically, gay men are nearly two and a half times more likely to develop a smoking habit than straight men. Lesbians are twice as likely compared to straight women, and people who are bisexual appear to have the highest risk of all.

To be clear, no one within the LGBT community is more prone to smoking because they're gay. The elevated risks are the result of common factors that are magnified within the LGBT community, namely stress and aggressive marketing techniques by tobacco companies.

Do these shoes make my butt look smaller?

Some shoemakers have enjoyed booming sales growth, thanks in part to shoes that promise to tone legs and glutes. Reebok's share of the U.S. women’s athletic footwear market more than doubled and Skechers tripled in the first quarter from a year ago, according to Bloomberg News.

According to a news article from Bloomberg, the success of these toning shoes prompted a Nike executive to joke, "Wouldn't it be great if we could make a pair of shoes that made your butt smaller, made my gut look smaller, make your muscles look a little bit bigger, just by putting them on and...walking in them?" Eric Sprunk, vice-president for global product and merchandising at Nike, said to an audience in May.  "Nobody can do that. I was just teasing."  Nike has not produced any toning shoes.
