A president without a college degree? Wisconsin governor will test it

On paper, Republicans' best presidential candidate for 2016 would seem to be the sitting governor of Wisconsin, except for one possible problem: He never graduated from college.

Walker won statewide gubernatorial elections in the swing state three times in four years, most recently winning his second term this past fall with over 52 percent, The New York Times reported. Walker's three wins include a recall election sandwiched between his first- and second-term races.

With the Republican presidential landscape notoriously tight, with few states to spare in most scenarios, Walker's apparent capacity to put the historically blue Badger State in play should make him an attractive candidate.

Does the fact that he never finished college present a significant barrier?

"I say I'm like the majority of people in America," Walker told Hugh Hewitt on his radio show earlier this month. "I'm someone who went to college, had the opportunity in my senior year to go and take a job full-time, which was not the only reason I went to college, but one of the biggest reasons was to get a job. And the American Red Cross offered me a job my senior year, and I took it, thinking someday, maybe, Id go back."

"Walker's right," notes the Washington Post. "Most Americans haven't completed college. Data from the Census Bureau put the percentage of adults over the age of 25 that have finished college at 31.7 percent in 2013 up significantly since the 1960s, but still indicating that two-thirds of Americans don't own that expensive bit of paper."

On one level, the lack of a college degree actually has cachet. The list of prominent businessmen and entrepreneurs without a college degree includes Apple's Steve Jobs, Facebook's Mark Zuckerberg, cable mogul Ted Turner, Microsoft founder Bill Gates and Whole Foods CEO John Mackey, to name a few.

The aforementioned list would seem to give the lie to any notion that a college dropout can't manage a large organization, such as the state of Wisconsin. Nor is there much evidence that holding an advanced degree from Harvard or Yale, like our last two presidents, makes one a brilliant leader or manager.

However, the electorate may feel otherwise. If Walker does run and win, it will be the first time since Harry Truman in 1946 that a president without a college degree has been elected. And Truman's win carries an asterisk, in any case. Truman was selected by Franklin D. Roosevelt as vice president in 1944 and never ran for president independently before holding the office after FDR's death.

The last president to win the office independently without already holding the office via the death of a sitting president was Grover Cleveland, first elected in 1885, Rasmussen College notes on its website.
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.
