The "most flexible" institutions in American higher learning should be as automatic as high school, Vice President Joe Biden said in the White House Weekly Address this past weekend.

Its simple, folks two years of community college should become as free and universal as high school is today if were to make this economic resurgence permanent and well into the 21st century, Biden said.

Its a simple fact that community colleges are the most flexible educational institutions we have, Biden said. Making community colleges free is good for workers, its good for companies and its good for our economy.

Biden's address was a follow-up on President Obama's controversial proposal earlier this year to make community college free for kids whose parents earn less than $200,000 a year.

That proposal evoked widely divergent responses from experts at the time. Some feared that it would channel more students into underperforming and underfunded schools. Others thought that it would encourage more middle class students to attend community colleges, broadening their appeal to legislatures.

Anything identified as 'for the poor' is easier to cut, Matt Reed, vice president for academic affairs at Holyoke Community College in Massachusetts, told U.S. News. He argued that a middle-class identity would offer political protection to community colleges.

Reed's analysis on the politics is a direct echo of Franklin Roosevelt's famous 1941 comment about using Social Security taxes to turn the program into a broad-based entitlement rather than a charity program that could be axed.

We put those payroll contributions there so as to give the contributors a legal, moral and political right to collect their pensions and their unemployment benefits," FDR said. "With those taxes in there, no damn politician can ever scrap my Social Security program. Those taxes arent a matter of economics, theyre straight politics.

Arizona offered a case study in such political calculus. The state legislature last month actually zeroed out state support for two major community college districts.

"The cuts are following an annual trend in Arizona in reducing money for higher education," Inside Higher Ed reported, "But what is striking in Arizona is the drop from at least several million dollars to zero."

As things stand, community colleges do struggle to deliver on their promise. As Richard Kahlenberg noted in the Atlantic, "Being cut off from financial and peer resources takes a toll on community-college students today. Research finds that though 81 percent of first-time community-college students enroll in school expecting to transfer to a four-year institution and get a bachelor's degree, just 12 percent end up doing so after six years."

Kahlenberg argues that making community colleges free to middle class kids would enhance their political appeal and create stronger peer effects, energizing the campuses as centers of opportunity.
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.
