Duke may have one of the best law schools in the country, but in recruiting new students, its promotional materials point out that Durham's bar scene has exploded in the past few years.

At Carnegie Mellon, the pitch is similar: "Pittsburgh rocks after dark," prospective students are told.

The story is the same at schools across the country. The "student experience," which often includes binge drinking and raucous parties for undergrads, is for many students as important as getting good grades and a degree.

The Maharishi University of Management in Fairfield, Iowa, might as well be on another planet. Its consciousness-based education involves daily transcendental meditation for its 1,200-something students, organic vegetarian meals, and four hours a week of required physical activity. Its ideal routine stresses rest as the basis of activity, including a "strongly" encouraged 10 p.m. curfew.

That early bedtime curtain call may be what prospective students thought they left behind in grade school. But the universitys routines, particularly regular transcendental meditation practice which involves sitting comfortably with eyes closed is not invasive, says Craig Pearson, Maharishis executive vice president.

Meditators report that once they begin to meditate, they naturally find themselves taking better care of themselves," he says. "But its not necessary to embrace any different lifestyle.

And, according to Pearson, students who meditate can expect to see a variety of benefits, from increased grade point averages to better focus, memory, energy, ego development and brain integration. Meditation, he adds, can also improve relationships and lower stress and anxiety levels. The benefits usually begin to be evident quickly, he says.

With its daily meditation, Maharishi is a good test case for the efficacy of meditation for students. But other schools, including Brown University and UCLA, have found benefits to meditative practices without making it a requirement.

Increasingly mindful campuses

Meditation has quietly taken place on campuses since the 1970s, but it has been spreading on a larger scale in the last five years, says Diana Winston, director of mindfulness education at UCLAs Mindful Awareness Research Center.

In the past decade, significant research has demonstrated that mindfulness can help lower blood pressure, boost immune systems, increase attention and focus, help with anxiety and depression and thicken the brain in areas in charge of decision making, emotional flexibility, and empathy, says Winston, who spent a year in Burma as a nun and has practiced mindfulness meditation for 25 years.

I dont think mindfulness meditation is for everyone, although many people find it to be extremely helpful, she says.

Statistics on mediation are tough to come by. Pew's most recent U.S. Religious Landscape Survey (2008) found that 39 percent of adults claim to meditate weekly. (Buddhists self-declared higher rates: 61 percent, as did Jehovahs Witnesses: 72 percent; Mormons: 56 percent; and members of historically black churches: 55 percent.)

A National Institutes of Health study in 2007, meanwhile, found that 9.4 percent of nearly 25,000 respondents had meditated in the past 12 months, compared to 7.6 percent of respondents in a study five years prior.

Catherine Kerr, assistant professor of family medicine and director of translational neuroscience at Brown Universitys Contemplative Studies Initiative, has observed growing interest among students in her courses on cognitive neuroscience of meditation.

Mindful meditation, she says, is a secularized practice whose origins lie in Buddhism, although it is put in a kind of secular framework. The practice, she says, owes a lot to the work of Jon Kabat-Zinn, the founding executive director of the Center for Mindfulness at the University of Massachusetts Medical School who also founded the university's Mindfulness-Based Stress Reduction Clinic in 1979.

The scientific evidence for transcendental meditation which is based on the spiritual practices of the Hindu leader Maharishi Mahesh Yogi who died in 2008 is comparatively weaker, according to Kerr. The gold-standard studies are not that strong, she says, although she notes that many people, including long-term practitioners, report positive results.

Minding the gaps

At Brown, students are encouraged to meditate in addition to studying meditation. One of the things that we see is that its really hard to describe from the outside what a practice is going to feel like, Kerr says. So its very helpful to get a taste of that. And, she says, some students come away from Browns meditation labs unconvinced "that practice is the best thing since sliced bread."

We want people to have a genuinely critical perspective on this, because we think right now in the culture theres actually this very strong pro-meditation, pro-mindfulness wave, and we are very concerned about that, she adds. We want to teach our students to be critical about a mindless approach to mindfulness.

That mindless mindfulness, which is more wishful thinking than good science, can be manifest in Huffington Post articles, for example, which make it sound as if 100 percent of people who do this practice benefit, and there are no adverse experiences ever. Thats just not true, Kerr says. The big issue is that the media overstates the scientific findings in relation to mindfulness.

The slight increase Kerr has seen in the number of Brown students who, for religious or spiritual reasons, travel to Asia, visit monasteries or join Buddhist practice groups pales in comparison to the "real growth." The latter, she says, occurs among students who major in neuroscience, have seen brain data, and want to know more.

There is, she notes, a great deal of distress in todays culture about stress and fragmented attention due to mobile devices. Meditation seems like a panacea to that, and its just not, she says. And the obsession with "training" the brain fails to understand how brain change actually works, and if it's beneficial. Further, changing brain structure is a bizarre goal.

Its kind of like choosing a restaurant based on a chemical report about a recipe," she says. "You should really be thinking about what does it taste like, and how does it make me feel?

Religious or secular?

At Saint Marys College of California, a Catholic school near Oakland, associate professor Jyoti Bachani recently used guided meditation on a daily basis in one of her classes. Meditation, she notes, is not necessarily religious in nature, and Bachani has used Kaiser healthcare podcasts, as well as programs from Stanford Health, in her teaching.

For people of faith, she says, religious components would add support to strengthen the practice, and we all need that.

Alan Brill, a rabbi and chairman of Jewish-Christian studies at Seton Hall University in South Orange, N.J., has noticed a rise in secular meditation and yoga and a decline in religious meditation. Instead of the teachers trained in mysticism or religious meditation of 25 years ago, today's meditation is likely taught as a practical skill by a guidance counselor, fitness coach or psychologist, he says.

Something may be lost in the translation from supernatural to secular, says Brill, who teaches courses on Jewish mysticism and spirituality. Besides the obvious the loss of God and the religious elements what is lost is much of the rich interiority and ethical concerns of the original paths, he says.

Last semester, an Islamic Syrian student of Brills, who wore a hijab, told him that she wanted to keep her meditative practices secular to avoid conflict with clergy. My Jewish and Christian students felt the same way about keeping the priests and rabbis out of it, he says. We live in an age of spirituality and religious as two separate variables, and therefore this separation is a mixed bag.
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.
