This little chameleon is one of four miniature lizards identified in Madagascar, adding to our growing list of amazingly teeny animals. The one on the match in this picture is a juvenile, but even the adults max out at 30 millimeters. They're the smallest lizards in the world, and some of the smallest vertebrates found to date.
This little guy is officially the smallest vertebrate on the planet, averaging 7.7 millimeters in size, less than one-third of an inch. Named Paedophryne amauensis, the new species of frog was discovered in Papua New Guinea, where it lives in leaf detritus on the rainforest floor.
At the Vienna Institute of Technology, a group of engineers claims they've created not only the world's smallest 3-D printer, but also one that's so light and inexpensive that it could conceivably pave the way for truly domestic 3-D printing. Lost an earring or a cuff-link? Print one out (and congratulations on your fancy life). That's the future, and it might not be far off at all.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
