Image of plant wires ( source) This week on LASER we have a plant materials themed episode where we discuss cellulose nanocrystals for use in composites, using plants as wires for computing, and using green tea to synthesize gold nano-stars for cancer treatments, drug delivery, and photonics. 2:00 Introductions and Emily explains the shiny new lab …

Source: Michigan Tech News This week on LASER we discuss Perovskite solar cells with organic charge transport layers, the horrible health effects of illegal backyard gold ore refining in Indonesia, and a new free open source metal 3-d printer from Michigan Tech. This show is also the first one we ever recorded entirely over the internet. 1:30 intro…

Just a quick update about our plans for the future, and some begging for ratings and reviews, topic suggestions, and interviews. Now that we’re 10 episodes deep, and finally getting the hang of this podcasting thing, its time to start trying to expand our listener base, and make a couple changes to the show. We’re going to start recording short pie…

(sources: schaft and NASA) This week on LASER, a super-sized cast discusses Semiconductor design/processing, Google robots and the DARPA robotics Challenge, a proposed form of space-based propulsion called e-sails, and the extension of the ISS mission until at least 2020! 2:00 we do some extended introductions this week, since we realized we haven’…
