Episode 21: 4/30/14: Maximizing Stiffness

Have you ever wanted to draw RIGHT INTO THE AIR?  Now you can, with a kickstarter product dubbed "the smallest 3D printing pen in the world."  It uses moldable plastic instead of ink, and creates 3D lines with every stroke you make.  Nina's on board, especially since Reno figured out how to "erase" mistakes you might make when drawing your 3D model.  Should you want to hang up your 3D creations when you're finished, maybe you can use "geckskin," a product that uses gecko-inspired characteristics to "maximize stiffness" and adhesion.   Also discussed are cloaked DNA nanodevices, lasers that create rainstorms, whether or not myelin is an insulator or aides in improved connections.  And for all our scientists/mathematicians out there, our final article explains what happens chemically in your brain when you fall in love. https://www.kickstarter.com/projects/lix3d/lix-the-smallest-3d-printing-pen-in-the-world/descriptionhttp://www.iflscience.com/health-and-medicine/3d-printed-cast-speeds-bone-recovery-using-ultrasoundhttp://www.kurzweilai.net/cloaked-dna-nanodeviceshttp://www.kurzweilai.net/gecko-like-adhesives-now-work-on-real-world-surfaceshttp://www.kurzweilai.net/laser-could-trigger-rain-and-lightninghttp://www.iflscience.com/plants-and-animals/climbing-plant-ultimate-master-disguisehttp://www.kurzweilai.net/less-myelin-found-in-neocortex-the-future-of-the-brain https://www.facebook.com/l.php?u=http%3A%2F%2Fn.pr%2FPudu5v&h=2AQGBRBiM https://www.facebook.com/l.php?u=http%3A%2F%2Fn.pr%2F1h2fF7Y&h=2AQGBRBiM  http://www.npr.org/2014/04/25/301824760/what-happens-to-our-brain-when-we-re-in-love?sc=tw
