Teens may be even more distracted behind the wheel than previously thought

Giving in to the temptation to talk with friends or answer texts while driving holds serious consequences for teens behind the wheel, according to a new study from the AAA Foundation for Traffic Safety, which found that six in 10 car crashes involving teen drivers were linked to distracted driving.

"Access to crash videos has allowed us to better understand the moments leading up to a vehicle impact in a way that was previously impossible," said AAA president and CEO Peter Kissinger in a press release. "The in-depth analysis provides indisputable evidence that teen drivers are distracted in a much greater percentage of crashes than we previously realized."

The study investigated nearly 1,700 crash videos "from an in-car system many families install in the vehicles of young drivers to keep track of their movements and habits," The Washington Post reported.

The Post's coverage included a video of accident clips, showing teens texting before veering off the road and slamming on the brakes after being distracted by a friend in the passenger seat.

Of the crashes linked to distracted driving, 15 percent were due to the drivers' interaction with other passengers and 13 percent were attributed to cellphone use, The New York Times noted.

"Half the time in rear-end crashes, teenagers using cellphones failed to react at all in the moments before the crash," the Times reported.

AAA's press release highlighted the importance of laws that limit teen drivers' access to risky behaviors. "Thirty-three states have laws that prevent cellphone use for teens and 18 states have passenger restrictions," it noted.

But with or without laws to back up their rules, parents "play a critical role in preventing distracted driving," according to the AAA. They can set ground rules at the beginning of their driving careers, making it clear that distracted driving is not an option.

"Parents need to talk to their kids early and often about safe driving (and) they should reinforce what they say by modeling safe driving practices," notes a resource guide for teen driver safety from Find Youth Info.

Additionally, the Centers for Disease Control and Prevention compiles safety research on its website, encouraging parents to talk to their kids about the "eight danger zones" impacting teen drivers, which include driver inexperience, driving with teen passengers, night-time driving, failing to use seat belts and drowsy driving.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
