Is the media's treatment of Black Twitter racist or an attempt at diversity?

It's hard to deny Twitter's influence in the race tensions, riots and acts of terrorism that have occurred in the past year. Viral hashtags like #BlackLivesMatter and #ICantBreathe not only gave a voice to those outraged over racism, but they forced the mainstream media to pay attention as well.

Enter Black Twitter, a community within Twitter dedicated to raising awareness and discussing race-related issues that created the hashtags that captured the country's attention in the wake of Ferguson, Missouri, and subsequent race conflicts of late.

"Black Twitter can move mountains," Stereo Williams wrote for The Daily Beast. "The murders of Trayvon Martin and Mike Brown, the reality of street harassment, the racial crisis brewing in the Dominican Republic these are all stories that became of major importance because Black Twitter made sure the world understood what was happening."

Black Twitter has become so influential that the L.A. Times has assigned a reporter specifically to cover it, and some critics worry the move might be one of exploitation rather than an attempt to better cover minority populations.

L.A. Times editor Mitra Kalita hinted at the newsroom's general ignorance of Black Twitter in the leaked memo announcing the new Black Twitter beat.

"Dexter Thomas joins us today to cover Black Twitter (which really is so much more complicated than that)," the memo read.

It's the ignorance of much of the news media about Black Twitter that worries journalism professor Meredith D. Clark.

"What media elites call 'exploration' of diverse groups online can be justifiably characterized as exploitation by members of the communities weve failed to connect with and cover for so long," Clark wrote for Poynter.

While media outlets like the Times and Vox attempt to better cover minority groups with measures like making Black Twitter or gender issues specific reporting beats, Clark suggests the outlets might go a step further and try to diversify their newsroom staffs as well.

Until then, Thomas, the Times' new Black Twitter reporter, hopes to take the mystery out of Black Twitter and race issues for a diverse audience.

"As far as mainstream media are concerned, (Black Twitter is) mostly police brutality activism and tweets about Beyonce," Thomas told Poynter. "Most of the coverage has been heres whats Black people said on Twitter yesterday. Theres no understanding of it."
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.
