Have You Seen This? Small human in big wave is dazzling

THE CURL Surfing a few 4-foot waves for fun and fitness is one thing, catching and surviving a 70-foot plus wave is quite another.

Big wave surfing is not so much a sport as it is a death defying stunt where you have zero control over most of the variables. You cant build a ramp to spec or place pads around you as you practice your skill; all you can do is wait for the big waves then pit your skill and soft, fleshy body against a wall of water with the force of the tide behind it.

In this featured video, you can get a sense of the danger and thrill of riding a big wave from the comfort of your own home. Its a gift that only skilled drone pilots can give us.

Prepare to be filled with awe and wonder as Sebastian Steudtner, 32, catches the monster wave. The video description doesnt say how big the wave is when this professional big wave surfer from Germany caught it, but it was estimated to be 80 feet at its peak as it made its way to the Praia do Norete in Nazar, Portugal.

In many surfing videos, it feels that surfers are casually slipping down a gentle slope of water. But as the drone zooms out, you get a real sense of how tiny and insignificant Steudtner appears against the massive wall of water. If youre not careful, viewing the video is almost enough to give you an existential crisis.

The incredible run was filmed by Mquina Voadora Produes (Flying Machine Productions), a local company in the area. Steudtner caught the wave on January 18 and the video was posted at the end of March.
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.
