Have you Seen This? Dog plays dead to stay at park

If you had older brother, you are familiar with this dogs technique called dead weight. I can tell you from experience that this method that involves letting your entire body go limp, making it more difficult to be dragged or carried, is terribly effective. It doesnt matter if youre a 65-pound child or golden retriever, that dead weight will hinder anyone trying to get you to move. - photo by Martha Ostergar

THE DOG PARK I hope we all remember that feeling we had as children, wanting just one more run down the slide or one more ride on the swings before heading back to the boring old house. The park was the place to be.

It seems that dogs have similar feelings as you can see (and hear) from a dog who complains loudly when told its time to leave the park, and from a dog who displays an entirely different form of resistance in this video.

If you had older brother, you are familiar with this dogs technique called dead weight. I can tell you from experience that this method that involves letting your entire body go limp, making it more difficult to be dragged or carried, is terribly effective. It doesnt matter if youre a 65-pound child or golden retriever, that dead weight will hinder anyone trying to get you to move.

As the dog lies completely limp on the ground, the owner tries talking, poking and prodding, and even a bit of dragging to get his reluctant beast to move. Its not until the dog thinks he might get a game of fetch that he even budges.

Sometimes bribery of treats or activities is the only way to break a will of iron like this dogs ... or most toddlers.
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.
