For kids in developing world slums, dental hygiene is a real problem. With this cheap gum developed by a team of college students, they might be able to have their candy and clean teeth.
"The thing with gum is that you want it because it’s tasty. The health benefits are almost extra," says one of the gum’s creators, Josh Tycko. "Toothpaste is seen as extra expenditure for long-term dental care that is too far on the horizon to be thinking about when you’re living on a small budget."
“I got plugged into the fact that if I focus my efforts on helping other people get sober, then I can stay sober—and that’s why giving people a second chance is so important to me.”
Today, Michael Dadashi is the CEO of MHD Enterprises, a multi-million dollar e-waste recycling company based in Austin. But five years ago he was a heroin addict who couldn’t keep a job and nearly lost his life to an overdose—and that was his turning point.

For the first time, scientists have created early-stage embryos using cloned cells from adults.
A study from Advanced Cell Technology published Thursday in the journal Cell Stem Cell highlights how researchers were able to create embryos from the skin cells of two men, ages 35 and 75. Tissue from the embryos featured exact DNA matches with the donors.
If you want to be happy, living near a park could be a good idea. More and more research shows a relationship between green space and higher levels of mental health.
The latest comes from the University of Wisconsin-Madison. Researchers looked at 2009 survey data that asked 2,500 residents about depression, anxiety, and stress.

Finally, there’s a socially acceptable reason for men to take pictures of their penises and post them to the Internet: The latest trend on Instagram and Twitter is #cockinasock, and it’s intended to raise awareness for testicular cancer.

“Fifty was a shock, because it was the end of the center period of life. But once I got over that, 60 was great. Seventy was great. And I loved, I seriously loved aging. I found myself thinking things like: ‘I don’t want anything I don’t have.’ How great is that?”
Neuroscientist Bevil Conway believes scientists can learn a lot from examining the strategies artists use to clarify color. “The best access we have of what color is and what it does to us is by studying the work of people who have studied it obsessively. Matisse is one of those people,” he says. “I think it’s extremely valuable, and there’s been very limited work treating that corpus as the sort of scientific evidence that it will turn out to be.”
