Earth's 'next door neighbor' could be home to WATER: New simulations suggest planet just outside of our solar system may be a 'highly habitable' world with a liquid ocean

A nearby exoplanet orbiting within the habitable zone of a star just 4.2 light-years from Earth may be home to a vast ocean, boosting its chances of supporting life.

Since its discovery, questions about the conditions at the surface of Proxima b have been swirling; the planet’s mass is just about 1.3 times that of Earth’s, and the red dwarf star it circles is similar in age to our sun, according to Daily Mail.

Studies over the last few years, however, have both bolstered hopes of its habitability and shot them down.

Why you trust your gut instinct over logic

 People feel more confident in snap decisions which come from their 'true self'

People often trust their gut instincts over logic because they feel those decisions are a more accurate reflection of their 'true selves', say scientists.

Because we see these choices as a better representation of who we are, we are more likely to have confidence in them, a study suggests, according to Daily Mail.

Scientists said while gut decisions come with several benefits, it can make us stubborn and unhappy to accept when we are wrong.

Tiny brain chip implant could help curb epileptic fits by detecting the 'electrical storm' that occurs before seizures start

An electronic chip implanted in the brain could help to prevent epileptic fits, a study suggests.

The device, so far tested only in mice, can detect the ‘electric storm’ that occurs in the brain when a seizure starts and release a natural chemical to stop it, according to Daily Mail.

The chip, made from plastic and twice as thick as a human hair, could be scaled up and trialled in people within two years

Around 600,000 people have epilepsy and three in ten are unable to control their seizures as anti-epileptic drugs do not work for them.

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.
