Researchers 3D print prototype for 'bionic eye'

A team of researchers have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a "bionic eye" that could someday help blind people see or sighted people see better, according to Science Daily.

"Bionic eyes are usually thought of as science fiction, but now we are closer than ever using a multimaterial 3D printer," said Michael McAlpine, a co-author of the study and University of Minnesota Benjamin Mayhugh Associate Professor of Mechanical Engineering.

Hubble spots gigantic 'eye in the sky' planetary nebula

It looks uncannily like an eye in the sky, staring back.

In face, this amazing image, captured by the Hubble Space Telescope, shows the planetary nebula NGC 3918, a brilliant cloud of colorful gas in the constellation of Centaurus, around 4,900 light-years from Earth.

It's 'eyeball' is actually dying remnants of a red giant star - and is a glimpse of what will one day happen to our own sun, according to Daily Mail.

During the final convulsive phase in the evolution of these stars, huge clouds of gas are ejected from the surface of the star before it emerges from its cocoon as a white dwarf.

Adult-child conversations strengthen language regions of developing brain

 Young children who are regularly engaged in conversation by adults may have stronger connections between two developing brain regions critical for language, according to a study of healthy young children that confirms a hypothesis registered with the Open Science Framework. This finding, was independent of parental income and education, suggesting that talking with children from an early age could promote their language skills regardless of their socioeconomic status, according to Science Daily.

Although decades of research have established a relationship between socioeconomic status and children's brain development, the specifics of this connection are not known. The so-called "word gap" -- the influential finding from the early 1990s that school-age children who grew up in lower-SES households have heard 30 million fewer words than their more affluent classmates -- and other evidence demonstrating an influence of early language exposure on later language ability suggests a potential influence of language experience on brain structure.

Palm oil: A new threat to Africa's monkeys and apes?

Endangered monkeys and apes will almost certainly face new risks if Africa becomes a big player in the palm oil industry.

That is the message of a study looking at how large-scale expansion of the oil crop in Africa might affect the continent's rich diversity of wildlife.

Most areas suitable for growing palm oil are key habitats for primates, according to researchers, according to BBC.

They say consumers can help by choosing sustainably-grown palm oil.

Killer whale mother finally lets dead newborn calf go, after 17 days

A killer whale has stopped carrying her dead newborn calf after at least 17 days, during which she covered 1,000 miles (1,600km), scientists say.

The whale "vigorously chased a school of salmon with her pod-mates in Haro Strait" off Canada's Vancouver Island, the Center for Whale Research said, according to BBC.

"Her tour of grief is now over and her behaviour is remarkably frisky."
