SBME Research Seminar: The RNA folding problem remains open – Dr. Rhiju Das
The discovery and design of biologically important RNA molecules has lagged behind proteins, in part due to the general difficulty of three-dimensional RNA structural characterization. What are the prospects for an ‘AlphaFold moment’ for RNA? I’ll describe some recent progress in modeling RNA structure from old-fashioned and new machine learning, cryoelectron microscopy, and current and upcoming internet-scale competitions hosted on the Eterna, Kaggle, and CASP platforms.

Research Seminar: Designing exoskeletons to enhance human mobility – Steve Collins
December 7, 2023 @ 12:00 pm - 1:00 pm PST
Talk Abstract:
Exoskeletons and active prosthetic limbs could improve mobility for hundreds of millions of people, but two serious challenges must first be overcome: we need ways of identifying what a device should do to benefit an individual user, and we need cheap, efficient hardware that can do it. In this talk, we will describe an approach to the design of wearable robots based on versatile emulator systems and algorithms that automatically customize assistance, which we call human-in-the-loop optimization. We will discuss recent successes of the approach, including large improvements to the energy economy and speed of walking and running through optimized exoskeleton assistance, in both laboratory and real-world settings. We will also discuss the design of exoskeletons that use no energy themselves yet reduce the energy cost of human walking, and a new type of actuator based on ultra-efficient electroadhesive clutches that could allow wearable robots to operate far longer with a given battery. Finally, we will briefly touch on the role of Science Robotics in publishing biomedical research, and on a new initiative to support design education: making@stanford.
