In the 1970s Wonder Woman TV show, the superheroine's invisible plane looked more like a glass plane. Which was, though not true to the comic, just as cool. And in fact a whole generation of TV-watching dorks grew up wanting glass planes as a result. Now those Wonder Woman fans may get their wishes. Researchers have made a major discover about the way glass functions at a molecular level - and as a result, they may be able to make super-hard glass that's as strong as steel. [Science Daily]
