Have You Seen This? Vacuum cleaner or human scream?

THE LIVING ROOM Once upon a time there was an invention called the vacuum cleaner (or Hoover, if youre British).

This invention was a blessing to every soul doing housework because it required less time and effort to dust rugs and carpets. It sounded too good to be true, and it was too good to be true.

Little did adult humans know that an evil creature was lingering inside each vacuum cleaner. Sure, the whirring motors were loud, but no one cared as long as the job got done. Noise is a small price to pay for easier cleaning. (Side note: Why hasnt science figured out how to make a quieter vacuum yet? Get it together, scientists.)

Adults scoffed and laughed at babies, cats and dogs when they cried out in fear each time a vacuum was turned on. The pets were the lucky ones as they could easily run and hide under the magically safe beds, but the babies, with their weak arms and legs, were forced to be still in their horror. They knew that non-dust-bunny evil somehow lurked inside those loud cleaning machines.

We adults have never been able to understand the true horror that lay inside until today. This video proves that monsters live in vacuums. Perhaps they are even humans trapped inside, forced to clean our carpets with great physical pain.

Just watch the video and listen to them scream.
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.
