Scanning Electron Microscopy (SEM) image of the bases of pretarsal (ie, on lowest part of leg) adhesive hairs. (A) On the left are the hair shafts of the adhesive hairs closest to the exoskeleton. At their insertion, the hair shaft becomes thinner and a stopper-like structure on the exoskeleton meets and atta...

Jet packs, robot maids, and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing (eVTOL) vehicles and designing and testing potential battery power...
