Scientists have found a woman whose eyes have a whole new type of colour receptor

After more than 25 years of searching, neuroscientists in the UK recently announced that they've discovered a woman who has an extra type of cone cell - the receptor cells that detect colour - in her eyes. According to estimates, that means she can see an incredible 99 million more colours than the rest of us, and the scientists think she's just one of a number of people with super-vision, which they call "tetrachromats", living amongst us. Most humans are trichromats, which means we have three types of cone cells in our eyes. Each type of cone cell is thought...

Could Earth’s Light Blue Color Be a Signature of Life?

In 1990, Voyager 1 captured the most distant portrait of our planet ever taken, revealing that from beyond Pluto’s orbit, Earth appears as nothing more than a “pale blue dot.” In a new study, researchers have tested whether Earth’s color is a unique feature of life-friendly planets. If so, searching for exoplanets displaying this hue could help in singling out worlds potentially brimming with alien life. As it turns out, Earth’s delicate color can be closely mimicked by hypothetical exoplanet types that are completely uninhabitable. A broader portion of Earth’s overall spectrum, however, does display a subtle signature only attributable,...
