Have You Seen This? What it's like to ride a scooter through Vietnam traffic

VIETNAM I have a reputation for being a terrible backseat driver. In my defense, some people are really terrifying drivers, and I only offer my opinion on their driving when I am scared for my life.

Of course, in their eyes, I'm usually overreacting and we were "totally safe" even though they didn't see the red light as we were getting off the freeway off-ramp. It's fine; I'm working on keeping my opinions to myself when I'm not the one at the wheel. But suffice it to say, I would not be able to stay quiet if I were in the situation of this driver.

The video shows a point-of-view shot of what it feels like to weave in and out of the hectic, busy roads in Hanoi, Vietnam. On a scooter, no less. Imagine my anxiety watching this guy squeeze his tiny vehicle between a semitruck, six other scooters and a few taxis.

The video is titled "It's less scarier than it look," which means whoever filmed it is probably used to driving this way and doesn't think it's a big deal. That's comforting, I guess. But I'm sure I'd still be yelling if I were in his position.
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.
