Weekly reading: Nikolov et al. on arthropod cuticle design principles

Hi everyone! For this week’s discussion, we will be reading a paper by Nikolov et al. (found here) discussing the mechanical properties of lobster cuticle as described using a set of nested, hierarchical equations. There are two papers that discuss this topic, of which, this is the less-technical. The other paper can be found here, and has some neat figures outlining the structure of the cuticle. Come ready to discuss how this model might be connected to and incorporated within an anatomy ontology, and how this might (or not) be useful in a phylogenetic context. There a few terms/concepts I really recommend looking up on Wikipedia before reading the paper, simply because they get used frequently (they are easy):

1.) Isotropic vs. Anisotropic

2.) Stress & Strain

3.) Young’s Modulus of Elasticity

4.) Poisson’s Ratio

Enjoy!
