The Australian Road Safety Foundation has launched an unusual community-based campaign to save young lives.

Residents are being encouraged to purchase a sticker featuring a life-size image of a child to place on their household garbage bins (they call them "wheelie bins") as a visual reminder to drivers that children might step into the street at any time while they're playing and distracted.

A release announcing the campaign says, "According to research from the Bureau of Infrastructure and Regional Development, Queensland road fatalities rose from 223 deaths in 2014 to 242 deaths in 2015. This reversed a three-year trend in which the number of national road fatalities had been declining." It noted that a big chunk of those deaths took place in daylight and involved cars on surface streets, where children might dart into traffic.

"We believe these stickers have the potential to have a real impact on our roads," said foundation CEO Russell White.

"We have seen some very effective road safety campaigns in recent years that highlight the danger that speeding poses to children crossing streets," White said. "The 'Life Saving' sticker campaign builds on this education process by providing a real-time reminder to motorists to reduce their speed."

"It is hoped drivers have an emotional reaction to the stickers, and think of the reality of a child running out onto the road," wrote Mashable's Johnny Lieu in a post about the campaign.

In the United States, many efforts have been made to teach children road safety and to remind drivers to be careful as well. For example, the National Center for Safe Routes to School (NCSRTS) at the University of North Carolina Highway Safety Research Center used funding from the National Highway Traffic Safety Administration to produce a "Safe Routes to School Guide" for parents and caregivers that focuses on how to teach kids to walk and play safely.

"Just as teenagers must first practice judgment and skills with an adult present and in simple traffic conditions, children need help learning and practicing where and how to walk safely," the guide says. "To help children become safe walkers, adults must look at the world of traffic from a childs point of view and have an understanding of how childrens abilities to learn and reason develop over time. This guide is intended to help parents and caregivers match their guidance and expectations with their childrens abilities."

Safe Kids Worldwide says that "developmentally, kids cannot judge speed and distance of approaching vehicles until age 10." And it notes that 80 percent of child-pedestrian deaths take place away from intersections.

There's no indication proponents of the Australian campaign are worried people will get so used to seeing images of children running into the street that they may not notice when a real boy or girl does so.
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.
