A practical, quantitative electrostatics experiment

Quantitative nanoscale electrostatics of viruses.

Electrostatics is one of the fundamental driving forces of the interaction between biomolecules in solution. In particular, the recognition events between viruses and host cells are dominated by both specific and non-specific interactions and the electric charge of viral particles determines the electrostatic force component of the latter. Here we probe the charge of individual viruses in liqui...

Quantitative Wood Anatomy—Practical Guidelines

Quantitative wood anatomy analyzes the variability of xylem anatomical features in trees, shrubs, and herbaceous species to address research questions related to plant functioning, growth, and environment. Among the more frequently considered anatomical features are lumen dimensions and wall thickness of conducting cells, fibers, and several ray properties. The structural properties of each xyl...

Practical optimal experiment design with probabilistic programs

Scientists often run experiments to distinguish competing theories. This requires patience, rigor, and ingenuity—there is often a large space of possible experiments one could run. But we need not comb this space by hand—if we represent our theories as formal models and explicitly declare the space of experiments, we can automate the search for good experiments, looking for those with high expe...
