Podcast: Play in new window Transcript BOB HIRSHON (host): What do geckos stick to? Science labs aren’t all about petri dishes and microscopes. ALYSSA STARK (University of Akron): So we kind of are sliding them across the surface, and trying to measure the actual force it takes to make them slip. HIRSHON: The lizards are interesting to scientists because they can run upside down on wet surfaces – so they’re strongly adhesive but easily detached. Researchers test the stickiness of gecko feet.

Podcast: Play in new window Transcript BOB HIRSHON (host): This Amazing, Zoomable Universe-In-A-Browser Puts Everything In Perspective. From nanoparticles to galaxies, we can understand a lot about how our universe works--but it's hard to keep things in context. Can you really grasp how far you'd have to travel to reach Mars? Or wrap your head around the infinitesimally small size of a virus? A couple of awesome animations will help. The first one, from London-based designers David Paliwoda and Jesse Williams, is an effective way to see just how far away Mars really is. It's shrunk down to a 100-pixel scale. When you've got Mars down, look at this incredible Flash tool created by Cary and Michael Hwang. You can scroll with a mouse or touchscreen, but I recommend using the slider at the bottom, because then you won't miss any of the lovely animated gifs--from wriggling worms to pulsating Cepheid stars.
