Personality as plain to others as the (altered) nose on your face

Going under the knife for a younger-looking face does more than alter a person's own body image, according to a new study published this week in the journal JAMA Facial Plastic Surgery. It also changes how an individual's personality is perceived by others.

"Facial plastic surgery changes the perception of patients by those around them," wrote the researchers. "Traditionally, these interventions have focused on improvements in youthful appearance, but this study illuminates the other dimensions of a patient's facial profile that are influenced by facial rejuvenation surgery," namely, likability, social skills, attractiveness and femininity.

Study participants were shown a mix of pictures of women before and after plastic surgery and asked to "make guesses about (a woman's) personality based on the photos," Time reported. Procedures like face-lifts, eyebrow-lifts and neck-lifts were found to make a woman appear more likable and socially adept, but they did not significantly impact ratings of trustworthiness, aggressiveness, extraversion or risk-seeking.

As Pacific Standard reported in its coverage of the research, the results confirmed what most people already knew, at least subconsciously: appearance plays a large role in people's assessments of each other.

"The study provides additional evidence that we make snap judgments about people's personalities based on facial features," by taking upturned corners of the mouth to mean a person is happy and likable or that baggy lower eyelids represent exhaustion and grumpiness, for example, the article noted.

Michael Reilly, one of the study's co-authors and an assistant professor of facial reconstructive surgery at the Georgetown University School of Medicine, told The Washington Post that he pursued the research out of a sense of obligation to his patients.

"I really wanted to make sure that when I was offering cosmetic surgery to patients, that I was actually doing something good for them," he said, noting that part of his job is making patients aware of the wide variety of risks that accompany plastic surgery procedures.

Because the study did not investigate traits like wisdom, which might be associated with older age and, therefore, wrinkles, it remains unclear what aspects of perceived personality are lost in the pursuit of a younger-looking appearance, Time noted.

"We still have a long way to go before we can figure out exactly what we're doing to ourselves when we go under the knife for cosmetic procedures," Time reported. "We're changing our outward appearance, yes, but how that affects our inner selves and how others perceive us isn't and likely won't ever be entirely clear."
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.
