From Caging to Grasping

This paper digs into the relationship between cages and grasps of a rigid body. In particular, it considers the use of cages as waypoints to grasp an object. We introduce the concept of pregrasping cages, caging configurations from which an object can be grasped without first breaking the cage. For two-fingered manipulators, all cages are pregrasping cages and, consequently, useful waypoints to...

Caging helps proteins fold.

H ow do proteins fold spontaneously? The quest to answer this question has led to significant developments on theoretical, experimental, and computational fronts in the last decade (1–7). A combination of approaches has provided a detailed understanding of the nature of pathways and the transition states that the polypeptide chain encounters as it traverses the rugged energy landscape. Even as ...

Caging and Uncaging Genetics

It is important for biology to understand if observations made in highly reductionist laboratory settings generalise to harsh and noisy natural environments in which genetic variation is sorted to produce adaptation. But what do we learn by studying, in the laboratory, a genetically diverse population that mirrors the wild? What is the best design for studying genetic variation? When should we ...
