In August 1991, David had led the first team of UN weapons inspectors to look for biological weapons in Iraq.
Back in 1959, physicist Richard Feynman suggested that physicists look at biological systems to see how nature stores information and builds nanoscale structures.

Briana Williams, a molecular biologist at the Louisiana State University Health Sciences Center in Shreveport, and her colleagues decided to look for biological differences in 100 prostate tumors, matched for disease stage and other clinical factors.
We then look for biological relevance in these newly defined modules.
This emphasizes the importance of hybridizing all samples together when microarrays are used to look for biological differences in the large-scale organization of gene expression levels.
This gene set was then processed through the Gene Ontology Tools: Term Enrichment algorithm [ 34], allowing us to look for biological functions over-represented in our gene set.
HS-AFM just recently opened a new avenue to directly and closely look at biological molecules in action and even dynamic events occurring in live cells.
