Facebook users across the world have an entirely new way to react to statuses.

On Wednesday morning, the social networking site unveiled its new Reactions feature, which gives users a few more ways to react to a friend's Facebook status, post or photo. When users place their mouse over the Like option, six emoticons also pop up one for Like, Love, Haha, Wow, Sad and Angry to help users more accurately express how they feel about a status.

Every day, people come to Facebook to discover whats happening in their world and around the world, and to share all kinds of things, whether thats updates that are happy, sad, funny or thought-provoking, Facebook product manager Sammi Krug wrote in a statement. Thats why today we are launching Reactions, an extension of the Like button, to give you more ways to share your reaction to a post in a quick and easy way.

These Reactions may be new to the common Facebook user, but the social network has been testing them for more than a year in select markets, Krug wrote.

In fact, the concept of these reactions has been in development for more than a year. As I wrote about last October, Facebook decided on this new feature after receiving plenty of support for a Dislike button. But Mark Zuckerbergs global social network decided to use Reactions instead after reviewing Facebook user data and finding that specific emojis like hearts, laughing faces and teary sad faces were some of the most popular expressions used on the site.

Hearts were everywhere, Adam Mosseri, head of the Facebook news feed, told Bloomberg. Sometimes it was heart eyes. Sometimes it was a heart beating out of a chest.

These new Reactions can take some getting used to. Instead of just clicking "Like," users will now have to consciously think about which expression best shows their emotion. And though it does give Facebook a fresh new look, some users could find the new choices confusing or unhelpful, CNN reported.

To test your skills, here are 12 Facebook statuses weve created that youre likely to see on Facebook. Choose the corresponding Facebook emoticons that you think are the best match.

For these type of statuses, an old adage proves true: spread love.
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.
