Rash of suicides leads MIT to rethink student pressure

After a rash of suicides the Massachusetts Institute of Technology, including four in the past year and two in the last month, the school has announced plans to lighten workloads and offer better social support.

"Students talk about a workload that leaves time for little else," the Boston Globe reports. "MIT estimates that students should spend 12 hours per week on a 12-credit course, including lecture, lab and homework. But students say classes actually require much more time students with four courses can easily toil 70 hours a week," Delano said.

MIT is not the first prestigious university to suffer under this affliction. It was only last spring that the University of Pennsylvania was spinning. During the 2013-14 academic year there were six suicides at Penn.

"The biggest dangers are neurobiological," observed Steve Volk in Philadelphia Magazine during the Penn scare. "The human brain isnt fully developed until we are about 25 years old, particularly in regions associated with impulsivity and emotional regulation. In this context, even a healthy kid is likely to struggle with transitioning from the childhood home to whatever comes next. Now consider that mental illness often first manifests itself between ages 16 and 25."

In 2009-10, Cornell in upstate New York suffered six suicides in six months, as administrators scrambled to adjust policies to prevent them.

"In the last decade," Inside Higher Ed reported in 2010, "Cornell has tweaked its interpretation of the Family Educational Rights and Privacy Act to consider students their parents dependents, making it possible for administrators to notify parents of lagging grades or mental health problems without a students consent. It has trained more people including dormitory custodians to be on the lookout for signs of mental illness, and created a team that meets weekly to discuss students observed by police and administrators to be struggling."

To be fair, one of the recent suicides cannot be directly linked to school pressure. Christina Tournant, the MIT freshman who apparently took her own life earlier this month, had severe medical issues and had taken leave from school. The Tech, MIT's campus newspaper, reports she "had been suffering from postural orthostatic tachycardia syndrome for the past two years. The syndrome caused her severe pain and circulatory issues. Her condition worsened in December, and in February, she took medical leave from MIT."

And MIT Chancellor Cynthia Barnhart noted to the Boston Globe in an interview that MITs undergraduate suicide rate has fallen in recent years: "Between 1994 and 2005, the rate for undergraduates was 18.7, but it fell to 12.6 for that group over the past decade."
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.
