High-tech material used to create a thin, flat fisheye lens

Ultra wide-angle fisheye lenses are typically thick, bulbous contraptions, that can't easily be incorporated into devices such as smartphones. That could be about to change, though, as engineers have now created one that's completely flat.

Diamond planets could be born from carbon-rich worlds – just add water

Perhaps on other planets, diamonds are as common and boring as rocks. Astronomers suggest that some planets might actually be largely made of diamonds, and now a team has calculated how such a planet could form and how it would be structured.
