The Department of Education hosted a Games for Learning Summit in New York City this month, reports Tech Times, bringing together educators, student and parents as well as video game producers and publishers in an effort to find the best way of harnessing technology for education.

"I think the education community is ready to really use technology in innovative ways," said Richard Culatta, director of educational technology at the U.S. Department of Education.

The Department of Education organized the event as part of President Obamas ConnectEd program, which focuses on bringing technology to K-12 classrooms across the country, according to Tech Times.

The interactive nature of video games makes them a useful educational resource.

"Video games can really provide formative, quality assessment about how a kid tackles a problem and how they fail and overcome the challenges around a certain context a game provides them, said Erik Martin, the lead for Games for Learning at the Department of Education.

The idea of using video games to enhance learning has been implemented before.

Douglas Kiang, a teacher at Punahou School, personalizes lessons based on the video games his students play. Kiang uses Bartle Test of Gamer Psychology to determine students strengths, reports Education News.

If you look at the life of a student a lot of students play on average about 10,000 hours of video games by the time they are graduating high school. That is almost the same amount they are spending in schools, said Martin.

This summit follows the success of last year's White House Game Jam, hosted by the Department of Education. This event brought in developers to create video games tailored to educational needs, reported Tech Times.
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.
