Siblings battle and bolster each other. They are the only people who have a real inkling of what your childhood was like. And, it turns out, those opposite-sex siblings may actually help you develop the confidence you'll need in romantic relationships.

A study led by Pennsylvania State University researchers says that siblings can observe and interact in ways that bolster their ability to relate to others, such as when dating.

It was published in the Journal of Youth and Adolescence.

According to the Wall Street Journal, "The study found that opposite-sex siblings saw themselves as increasingly capable of attracting and interacting with the opposite sex during the period from early to late adolescence. But no significant changes in so-called perceived romantic competence were found in siblings of the same sex."

The benefit, the article said, came from "natural opportunities to practice relating to the opposite sex and learn important social skills that can be applied in other relationships, such as conflict resolution and emotional control. Siblings of different sexes may have a better idea of how challenging interactions with the opposite sex can be, whereas same-sex siblings may be unaware of how little they know, the study suggests."

Data for the study came from five annual interviews over a half decade with the oldest two children in 190 families that were part of a different research project. The siblings were no more than four years apart and ranged from 12 to 20 years old.

The questions focused on whether they'd be fun and interesting on a date. The researchers noted that at age 12, same-sex siblings seemed to consider themselves more competent in terms of romance. That changed significantly by age 20.

"The results revealed that youth with same-sex siblings showed no change in their perceived romantic competence, but those with opposite-sex siblings exhibited increases in romantic competence over time," the study said.

When they discounted what children learn from relationships with parents, they still saw that the more siblings interacted closely and agreeably with a sibling of the opposite sex, the greater their romantic competence. Those who primarily fought with the sibling had lower average romantic competence.

Lee Lofland compiled a bunch of sibling facts into a blog post, noting that children who have a sibling of the opposite sex are more likely to adhere to gender norms than those with only same-sex siblings.

And Huffington Post noted earlier this year that hanging out with an opposite-sex sibling increases one's comfort level around others of the opposite sex.
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.
