Have You Seen This? World record for most paper airplanes thrown into watermelons in 1 minute

WEIRD CITY I'm not very good at paper airplanes.

I think there was briefly a time as a kid when I knew how to make one that could fly a few feet if the conditions were just right. But since I don't regularly participate in paper airplane contests, I have forgotten all that knowledge. Now when I try to make a paper airplane, I'm better off just wadding the paper into a ball because, that way, it will at least go more than a few inches when I throw it.

Needless to say, I will never be able to participate in something as cool as this. The video comes from Guinness World Records and shows a true paper airplane champion doing something you've probably never even thought of before: throwing paper airplanes so hard that they stick into watermelons.

But not only is he throwing the paper airplanes into watermelons which I'm sure is a difficult enough task on its own but he's throwing as many as possible in under one minute, and breaking a world record while he's at it.

I have a lot of questions about this video, but I also think it's pretty amazing. As you'll see when you watch, paper airplane champion Junguk Lee from South Korea broke the world record by throwing 12 paper airplanes into watermelons in under 60 seconds. This is impressive because I can't even begin to imagine how you fold a flimsy piece of paper into an airplane sharp enough to puncture a watermelon. Doing so definitely requires more skill and talent than I have.

So, even though I'm still not exactly sure why this activity is a thing, I'm glad it is because I really enjoyed watching the video, and I think you will too. And congrats to Junguk Lee on that well-deserved world record.
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.
