TENNIS TOWN Being an elite athlete is a serious business with its years of non-stop training and tournaments, so its probably a relief for athletes to participate in events that dont require the standard giving 110 percent in sports.

Roger Federer and Grigor Dimitrov played an exhibition game on Tuesday at Madison Square Gardens. And while there was plenty of good play and a proper score was kept, the exhibition is traditionally home to shenanigans, including trash talk, trick shots and pulling people from the crowd to play.

The 2013 exhibition had Ben Stiller and a small girl playing doubles with Rafael Nadal and Juan Martin del Potro. This year the fun came in the form of Dimitrov pulling a boy from the crowd to volley alone with Federer.

The boy had obviously played before, and he hustled to return Federers shots and thats when it happened.

Federer was crowding the net when the boy hit a perfect lob over Federer's head that landed just inside the back line to give the boy the point, much to the delight of the crowd.

Yes, the boy was more than likely a pre-picked ringer, and yes, Federer was not hitting 100 mph shots back at the boy, of course. But its still got to feel a little not good to lose that point, especially when the chair ump takes a crack at you.

Ringer or no, no matter where that boys athletic career takes him, he will forever have the story of the time he beat Federer. Theres only a handful of people in the entire world who can say that.
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.
