This week on Txchnologist, NASA tested experimental rocket engine injectors that were 3-D printed to enhance performance over traditionally manufactured components. This 3-D printing technique, called direct laser melting, consists of a machine that fires a laser at metal powder under the control of a computer design program, depositing layers of the metal on top of one another until the part is produced. The hope? To demonstrate that 3-D printed designs can truly revolutionize system performance along with production time and cost.
A team led by biophysicist Markus Sauer and chemist Jürgen Seibel have pioneered a new microscopy method, dSTORM, which stands for direct Stochastic Optical Reconstruction Microscopy. This allows for the visualization of objects in super resolution, revealing details of cells ten times better than ever before by stitching together multiple images to create a single, sharper one. By resolving objects by mere millionths of millimeters across, researchers will inevitably gain new insights into activity in infectious diseases and cancer in human cells.
Harvard roboticists are in the process of constructing a soft-bodied, untethered robot that can continue operating through fire, water, crushing force, and even freezing conditions. Its body is constructed from a composite of silicone, fabric, and hollow glass microspheres. The group’s gains are an important step forward: If robots such as these are to perform rescue missions and survive demanding weather conditions, they need to be able to roam and slither free from cumbersome power connections.
