plan to 3D print new shells for homeless hermit crabs to this handy LeafSnap app that helps you identify all different kinds of fall foliage to an energy-efficient UFO hotel room, which recently "landed" in the forests of Sweden. Speaking of spaceships, we also spotted this Star Trek Enterprise feeding system for babies (you're never too young to live long and prosper) as well as plans for a massive nuclear-powered airport/airplane that could fly as many as 3,000 passengers through the sky, and Philips showed off its eerie and futuristic bacteria-powered lamps.

We also saw that GM is working on cars that could drop drivers off at their destinations and even park themselves, and the auto giant impressed us even further by joining Ford and Chrysler, who are working closely with engineering students from the University of Michigan Solar Car Team to create viable solar-powered cars for the future. But if you can't wait that long, this Solarship is a blimp-like solar-powered airship that actually exists today.
In tech news, Facebook announced that they'll be building a fancy new server farm in the Arctic. And speaking of cold weather, we also spotted where this clever Umbrella coat that has a handy umbrella instead of a hood - perfect for rainy fall days. A new study showing that TV is officially harmful to children under two confirmed some of our suspicions and we also saw news of a judge who ruled that cell phone warnings be blocked in San Francisco.
