Babies apparently would rather talk to other babies than their mothers.

A new study found that babies who are 5 months old would rather try to communicate with their peers than listen to baby talk from adults.

Researchers at the University of Quebec used a specialized speech synthesizer to test this theory. The device simulated human vocal sounds from a variety of ages and sizes. They then compared the babies responses to the sounds of vowels from babies their own age and from adult females, which was meant to represent mothers.

The researchers measured a response as a baby turning her head and listening to the voice.

The researchers found babies listened to infant vowel sounds 40 percent longer than they listened to adult vowels, showing a clear preference for vowels that closely matched the sounds they produce themselves, according to Quartz.

In fact, even a mothers best imitations of another baby werent enough to hold an infants attention. They heavily favored listening to a voice similar to their own, created by their small bodies.

"Access to infant speech, likely including a baby's own vocalizations, seems to have a broad and significant impact, influencing receptive, expressive and motivational aspects of speech development," said Linda Polka, a professor at McGill University.

The study, she said, will shed light on "how infants develop their understanding of spoken language what they bring innately and what is shaped by their experience as listeners and as 'talkers-in-training.'

According to Quartz, this isnt the first time research has suggested babies prefer babble sounds from other babies. Infants can understand those sounds more easily, which makes it a little less difficult to learn new words.

Babies are drawn to words that match the sounds they produce most often, helping them pick out words from the speech stream that theyre more likely to be able to produce, Quartz reported.
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.
