First time accepted submitter Philip Ross writes "Scientists at the University of Texas looked at the interactions between bacteria in 3D-printed environments to better understand what makes some microbes resistant to antibiotics, something health officials have been warning us about for a long time. They used high-precision lasers to print multiple two-dimensional images, using a chip modified from a digital movie projector, onto a layer of flexible gelatin where bacteria were growing. As layers of protein were added to the gelatin, which contains photosensitive molecules that become aroused and bond together after being hit with a laser, they formed a tiny encasing around the bacteria."
