How to Grip an Asteroid

Kimm Fesenmaier

Caltech junior Edward Fouad spent 10 weeks this summer as part of the Summer Undergraduate Research Fellowship (SURF) program working in the lab of Aaron Parness, a group leader at JPL, where researchers are designing, prototyping, and refining technology for a device called a microspine gripper. Looking something like a robotic circular foot with many toes extending radially outward, such a gripper has the ability to grab onto a rocky surface and cling to it even when hanging upside down.

Programmed to Fold: RNA Origami

Katie Neith

Researchers from Aarhus University in Denmark and Caltech have developed a new method for organizing molecules on the nanoscale. Inspired by techniques used for folding DNA origami—first invented by Paul Rothemund, a senior research associate in computation and neural systems in the Division of Engineering and Applied Science at Caltech—the team, which includes Rothemund, has fabricated complicated shapes from DNA's close chemical cousin, RNA.
