From fire ants to spider silk, tooth enamel to lizard scales, and chemistry to computer science, there are lots of opportunities for soft-matter scientists to study biological questions!
Spider silk: Sticky when wet
If you were Spider-Man, how would you catch your criminals? You could tangle them up in different types of threads, but to really keep them from escaping you probably want your web to be sticky (not to mention the utility of sticky silk for swinging between buildings) …
Scaling up biology
The difference between a bacterium and a whale are huge, and not just their size. However, there are hidden scaling laws underlying all living things. These scaling laws are found to be due to the fractal-like nutrient distribution systems. Here, we review how to derive the scaling law for metabolic rate with organism mass, illustrating its generality and ubiquity.
