People are more likely to cheat for monetary gain after watching a violent movie or reading a violent book, according to a new study from Brigham Young University.

Researchers said the finding suggests exposure to human violence in print or video media leads people to act more unethically, supporting several other previous studies. The team said this study is significant because it shows consuming violent media does more than just increase aggressive behavior towards others and can negatively impact businesses.

We hope this provides another piece of evidence to the debate were having within western society of the effects of media on behavior, BYU professor and study co-author Josh Gubler said in a statement. We hope this information informs parents and communities as they make decisions about what types of media they consume.

For the study, researchers carried out three different experiments involving a total of 1,000 participants. In one study where participants were instructed to edit sentences to get paid, those who were assigned to edit violent content were 24 percent more likely to cheat by reporting that incorrect sentences were correct in order to earn money faster, according to researchers.

One interesting finding is that while both men and women were equally likely to cheat after exposure to violent print media, only mens ethics were affected by video content, according to the study. To test the influence of video media, participants were paid to watch and evaluate movie clips. Researchers said the men who watched violent clips from movies were more likely to lie and say they watched all of their clips in their entirety to get paid.

In addition to the experiments, researchers examined observational data from various companies to determine whether exposure to violence in real life affects ethical decision making.

Companies headquartered in locations marked by greater human violence are more likely to fraudulently misstate their financial statements and exhibit more aggressive financial reporting, the studys abstract reads. Combined, our results suggest that exposure to human violence has significant and real effects on an individuals ethical decision making.

Multiple studies in recent years have suggested that violent media has a negative impact on society, according to BYU. A 2009 study from the University of Michigan and Iowa State University found people who recently watched a violent film took 26 percent longer to help an injured woman, while it took those who played a violent video game five times longer to help someone in need.

We have whole industries that glorify violence in video games, in media, in Hollywood and then, on the opposite side, we have a significant body of research showing very serious effects to this, BYU coauthor David Wood said in a statement. There is a disconnect between what science is saying and what we choose to do in society.

The study was published in the Journal of Business Ethics.
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.
