Flue gas from power plants is a cheap CO2 source for algal growth. We have built prototype "flue gas to algal cultivation" systems and described how to scale up the algal cultivation process. We have demonstrated the use of a mass-transfer bio-reaction model to simulate and to design the optimal operation of flue gas for the growth of Chlorella sp. in algal photo-bioreactors.

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.

More than half of proteins are small proteins (molecular mass <200 kDa) that are challenging for both electron microscope imaging and three-dimensional reconstructions. Optimized negative staining is a robust and high-throughput protocol to obtain high contrast and relatively high resolution (~1 nm) images of small asymmetric proteins or complexes under different physiological conditions.

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.
FAQs
Magnification should be considered alongside numerical aperture rather than adjusted in isolation. The overview identifies both as factors that influence image clarity and the amount of biological detail that can be interpreted. Selecting settings as a coordinated group helps match image quality to the specimen and microscopy method, supporting clearer visualization without relying on magnification alone.
Fluorescence settings require a balance between detectable signal and preservation of the sample. Excitation intensity and emission detection influence signal quality, while exposure time also contributes to the imaging conditions. Excessive excitation can increase photobleaching, so settings should provide sufficient fluorescence for interpretation while limiting unnecessary loss of signal during image acquisition.
Artifacts or sample damage can result when imaging parameters are poorly matched to the specimen or microscopy method. Focus, illumination, exposure time, detector gain, and contrast all contribute to the final image and must be balanced with the need to preserve biological structure. Careful adjustment reduces misleading image features and supports more reliable interpretation.
Standardization makes image comparisons more dependable by keeping relevant imaging conditions consistent. Recording and applying comparable magnification, numerical aperture, focus, illumination, exposure, detector gain, and contrast settings can reduce differences caused by acquisition rather than biology. This consistency supports reproducible image analysis and improves confidence when results are compared across samples, instruments, or research laboratories.
Begin by considering the specimen and microscopy method, then adjust magnification, numerical aperture, focus, illumination, exposure time, detector gain, and contrast as an interacting set of parameters. For fluorescence imaging, also balance excitation intensity with emission detection. Review whether the resulting image preserves structure, limits artifacts or damage, and provides sufficient information for the intended analysis.
Researchers should apply it whenever images will be used to visualize, measure, or compare biological material. The approach is relevant to cells, tissues, and subcellular structures, including fluorescence imaging where photobleaching can affect signal quality. Optimization is especially valuable before quantitative image analysis or comparisons involving multiple samples, instruments, or laboratories.
Optimized settings produce images that are more suitable for extracting and comparing biological information. By balancing clarity, structure preservation, signal quality, and artifact limitation, researchers can improve visualization and measurement of cells, tissues, and subcellular structures. Standardized acquisition conditions also strengthen reproducibility, helping distinguish meaningful biological differences from variation introduced by imaging.
