World’s Smallest Magazine Cover

While there’s no shrink ray in existence as of yet, scientists are hard at work at making magazines available for us, just in case we ever get down to the micrometer scale. In fact, a laboratory in Switzerland has managed to print an image so small that you could fit over 2,000 of them onto a single grain of salt. If they were to do this, the title of this article would be called “4,000 pandas on a grain of salt.”

The Australian heat wave is getting so hot that Australia’s Bureau of Meteorology had to add new colors to its weather map. There are parts of Australia that have achieved temperatures above 122ºF (50ºC), temperatures which were off the scale until recently.
