The physical limits to chemical sensing have been established and tested for single cells. However, recent experiments have demonstrated that cells can surpass these limits when they communicate. The theoretical limits to the precision of collective sensing are still poorly understood.

 I will discuss studies of the mechanics and structure of metaphase chromosomes and nuclei extracted from mammalian cells using glass micropipettes.

In sperm, DNA is tightly compacted to create a small, hydrodynamic sperm head. This dramatic reorganization of the nucleus is carried out by protamine proteins that fold the DNA into loops and toroids.
