Happy summer, all! Back in late June, Cathi and Nora connected virtually in the middle of a scorching heatwave to talk sustainable futures in retail and materials. Cathi brings you a plan by Ralph Lauren to let shoppers customize their own clothes, which would then be created on demand. The plan is also to disburse manufacturing more broadly, so clothes would be created closer to where they're purchased. Check out the interview with Chief Innovation Officer David Lauren in Fast Company.  Meanwhile, Nora brings you a cool story via Scientific American about 3D printing ink made from microalgae, as a sustainable material for household objects. Cathi and Nora are taking a much needed summer break, but will be back in late August fresh and ready to rock. Have a lovely, safe, summer!
