THE GUINNESS BOOK Confession: I have never solved a Rubiks Cube.

I know solving the handheld puzzle is all about patterns patterns you can now look up online, yet the solution has escaped me for decades.

Additionally, Ive never been able to juggle. My hand-eye coordination is just fine for every day (slightly clumsy) use, but all my juggling attempts have been for naught.

Yes, I know these particular confessions are boring, but I bet theyre relatable to many. And theyre also the reason why I was particularly blown away by this featured video.

In this Guinness World Record showing, youll meet 13-year-old Que Jianyu from Fujian, China. He recently won a world record for the fastest solve of three Rubiks Cubes while juggling them. (You can go back and read that sentence again. Ill wait.

According to Guinness World Records, this teen tyke spent two years training to be the fastest, and his world record clocked in at 5 minutes 6.61 seconds.

Now, that record time doesnt seem that fast compared to the 4.22 second-record for solving a single 3 x 3 x 3 Rubiks Cube. But frankly, I am just impressed that anyone can juggle for over 5 minutes without dropping anything, never mind the Rubiks Cubes. So basically, my mind was blown.

The record was filmed as part of a show called iDream in China. In true competition TV form, the music is dramatic, the cuts are dramatic, and the pacing is dramatic to really sell the intensity of the moment. Despite the cheese-factor of the manufactured drama, the video is worth the whole 4-minute watch.
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.
