Jing Li Receives AAAR Sheldon Friedlander Award


Jing Li, a postdoctoral scholar working with Professor Michael R. Hoffmann, is the recipient of the 2019 Sheldon K. Friedlander Award from the American Association of Aerosol Research (AAAR). The award recognizes an outstanding dissertation by an individual who has earned a doctoral degree in any discipline related to the physical, biomedical or engineering sciences in the field of aerosol science and technology. In her doctoral thesis, Jing focused on studying the global PM-borne biologicals and their toxicity, more broadly in bioaerosol field. Her dissertation work raises the awareness of airborne transmission of antibiotic resistance genes (ARGs), as well as global differences of local source-specific PM toxicity. [Past recipients]

Caltech Announces the Schmidt Academy for Software Engineering


Caltech has launched the Schmidt Academy for Software Engineering to train the next generation of science-savvy software engineers and set new standards in scientific software. "This is a recognition that computing, software, and machine learning are going to play a very big role in science. Because Caltech is small and collaborative, we have the opportunity to really make a push in that direction," says Kaushik Bhattacharya, the Howell N. Tyson, Sr., Professor of Mechanics and Materials Science and vice provost. [Caltech release]

Stewart and Lynda Resnick Pledge $750 Million to Caltech to Support Environmental Sustainability Research


Stewart and Lynda Resnick have announced a $750 million pledge to Caltech to support cutting-edge research into the most pressing challenges in environmental sustainability. "Stewart and Lynda Resnick's generosity and vision will permit Caltech to tackle issues of water, energy, food, and waste in a world confronting rapid climate change," says Caltech president Thomas F. Rosenbaum. [Caltech story]

New Polymer Heart Valve Implanted in First Patient


Professor Morteza Gharib, has designed a new generation of heart valves that are longer-lasting, cost less to manufacture, and are more biocompatible than options that are currently available to patients. One of the new valves has been implanted into a human for the first time. "This is among my proudest moments. Creating something with the potential to save and improve lives is one of the reasons I became an engineer," Gharib says. [Caltech release]

New Metamaterial Changes Shape in a Tunable Fashion


Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering, has developed a new type of architected metamaterial that has the ability to change shape in a tunable fashion. The material has potential applications in next-generation energy storage and bio-implantable micro-devices. [Caltech story]

Self-folding “Rollbot” paves the way for fully untethered soft robots


Chiara Daraio, Professor of Mechanical Engineering and Applied Physics, and colleagues have developed soft robotic systems, inspired by origami, that can move and change shape in response to external stimuli, paving the way for fully untethered soft robots. "This work demonstrates how the combination of responsive polymers in an architected composite can lead to materials with self-actuation in response to different stimuli. In the future, such materials can be programmed to perform ever more complex tasks, blurring the boundaries between materials and robots," said Professor Daraio. [Caltech story]

A Promising Step in Returning Bipedal Mobility


Professors Aaron Ames and Joel Burdick have launched a new research initiative, RoAMS (Robotic Assisted Mobility Science), aimed at restoring natural and stable locomotion to individuals with walking deficiencies that result from spinal cord injuries and strokes. RoAMS unites robotic assistive devices—including exoskeletons and prostheses—with artificial intelligence (AI)-infused neurocontrol. "Bipedal walking is difficult to achieve in a stable fashion," says Professor Ames. "While crutches help users of the exoskeletons to stay upright, they undercut many of the health benefits that upright locomotion might otherwise provide. In addition, they do not allow users to do anything else with their hands while walking." [Caltech story]

Finding the Magic in the Magic Angle


Stevan Nadj-Perge, Assistant Professor of Applied Physics and Materials Science, and colleagues have built upon, the discovery of the "magic angle" for stacked sheets of graphene, by generating an image of the atomic structure and electronic properties of magic angle-twisted graphene, yielding new insight into the phenomenon by offering a more direct way of studying it. They have developed a new method of creating samples of magic angle-twisted graphene that can be used to align the two sheets of graphene very precisely while leaving it exposed for direct observation.

Solar Flares, Bubble Rings, and Ink Chandeliers


Peter Schroeder, Shaler Arthur Hanisch Professor of Computer Science and Applied and Computational Mathematics, and colleagues have generated a computer simulation of underwater bubble rings that is so realistic it is virtually indistinguishable from a video of the real thing. "What drives me is finding these beautiful descriptions of something that looks terribly complicated but can be reduced to a few mathematical key concepts. Then the rest just follows from there. There's beauty in seeing that a very simple principle all of a sudden gives rise to the complex appearance we perceive," Professor Schröder says. [Caltech story]

Microrobots Activated by Laser Pulses Show Promise For Treating Tumors


MedE Professors Wei Gao and Lihong Wang are working on microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body. "These micromotors can penetrate the mucus of the digestive tract and stay there for a long time. This improves medicine delivery," Professor Gao says. "But because they're made of magnesium, they're biocompatible and biodegradable." [Caltech story]
