We describe the preparation of three test samples and how they can be used to optimize and assess the performance of STORM microscopes. Using these examples we show how to acquire raw data and then process it to acquire super-resolution images in cells of approximately 30-50 nm resolution.

Magnetic force microscopy (MFM) employs a vertically magnetized atomic force microscopy probe to measure sample topography and local magnetic field strength with nanoscale resolution. Optimizing MFM spatial resolution and sensitivity requires balancing decreasing lift height against increasing drive (oscillation) amplitude, and benefits from operating in an inert atmosphere glovebox.

Optimal Foraging - Concepts

Optimal Foraging Organisms must acquire and use resources in their environment to survive. While food is one of the primary resources organisms must search for, individuals also need to seek habitats, shelter, and mates. This process of searching for resources is known as foraging, which involves a series of costs and benefits. More specifically, acquiring a resource provides the organism with a benefit, however, searching and capturing the resource requires expenditure of time and energy.

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment. Optimal foraging theory states that natural selection favors foraging strategies that balance the benefits of a particular food, such as energy and nutrients, with the costs of obtaining it, such as energy expenditure and the risk of predation. Optimal foraging maximizes benefits while minimizing costs. For the Crows

Simulating Foraging with Artificial Habitats and Prey ExpandNOTE: The foragers will hunt for prey represented by pinto beans in four buckets of rice with varying prey densities. Without knowing what these densities are, foragers must obtain as many prey items as possible in as little time as possible. HYPOTHESES: In this experiment, the experimental hypothesis could be that foragers will catch the most prey in the higher prey density bucket and also spend the most time foraging there. The...
FAQs
Increasing resolution can create tradeoffs with signal-to-noise ratio, acquisition speed, sampling limits, and computational demands. A highly detailed measurement may therefore produce weaker or less reliable data, require longer acquisition, or increase processing requirements. Researchers select a practical balance based on whether the experiment prioritizes fine structural detail, rapid biological dynamics, dependable quantification, or manageable analysis.
Sampling limits determine whether the system can adequately represent the features being measured, while signal-to-noise ratio affects how confidently those features can be distinguished from unwanted variation. Resolution optimization must consider both factors together rather than treating detail alone as the goal. This balance supports reliable measurements of cells, tissues, biomaterials, and molecular signals.
The priority depends on the biological scale and dynamics under study. Spatial resolution is important when distinguishing structural features, temporal resolution when following changing biological events, and spectral resolution when separating molecular signals. Resolution Optimization therefore begins by identifying what information the experiment must preserve, then matching system settings to that specific measurement need.
These components influence different stages of data generation and interpretation. Optics shape how features are captured, detectors record the signal, acquisition settings control collection conditions, and processing methods refine or analyze the resulting data. Adjusting them as a coordinated system can improve visualization and quantitative analysis more effectively than changing one component without considering the others.
Start by identifying the relevant biological scale, dynamics, or molecular signal, then determine whether spatial, temporal, or spectral information is most important. Select suitable optics and detectors, set acquisition conditions, and account for sampling limits, signal-to-noise ratio, speed, and computational demands. Finally, evaluate whether the resulting data support accurate visualization and quantitative analysis.
A well-balanced system can improve visualization and characterization of cells, tissues, biomaterials, and molecular signals. These gains support more accurate quantitative analysis and can inform device or diagnostic development. The value lies not simply in producing finer detail, but in obtaining data that remain reliable and appropriate for the biological feature or process being investigated.
