Source: Weber, N. et. al., Natural Transformation, Protein Expression, and Cryoconservation of the Filamentous Cyanobacterium Phormidium lacuna. J. Vis. Exp. (2022)This video demonstrates a focused LED-based assay for studying phototaxis in filamentous cyanobacteria. The bacteria migrate toward the light source, forming a dense accumulation at the illuminated center, which is visualized and quantified through pixel intensity analysis of the captured image.

We recently identified a novel Drosophila circadian output, temperature preference rhythm (TPR), in which the preferred temperature in flies rises during the day and falls during the night. TPR is regulated independently from another circadian output, locomotor activity. Here we describe the design and analysis of TPR in Drosophila.

Highly Resolved Intravital Striped-illumination Microscopy of Germinal Centers

2014
High-resolution intravital imaging with enhanced contrast up to 120 µm depth in lymph nodes of adult mice is achieved by spatially modulating the excitation pattern of a multi-focal two-photon microscope. In 100 µm depth we measured resolutions of 487 nm (lateral) and 551 nm (axial), thus circumventing scattering and diffraction limits.
FAQs
These conditions can influence one another through changes in heat and mass transfer, material behavior, sensor response, and light-driven processes. A change in temperature may alter system thermal conditions, while humidity affects moisture-related behavior and illumination changes exposure at a surface. Evaluating the variables together therefore provides a more realistic picture of operating performance than considering each condition in isolation.
Humidity, temperature, and illumination can modify sensor response and the behavior of the materials or systems being measured. If these conditions vary during testing, observed changes may reflect the environment rather than the property under investigation. Controlling or documenting the conditions helps engineers distinguish environmental effects from genuine system performance and improves the reliability of measurements.
Environmental levels can change how materials respond and how reliably a system operates. Humidity is relevant to moisture-related behavior, temperature affects thermal conditions, and illumination influences light-driven processes at exposed surfaces. Because these effects can occur during normal operation or testing, engineers evaluate the conditions when assessing product performance, safety, durability, and consistency.
Engineers first identify the environmental conditions relevant to the system or product, then measure or control those conditions during evaluation. They can use controlled chambers to reproduce selected environments and compare system behavior under consistent settings. Recording the resulting performance helps connect environmental changes with material response, measurement accuracy, energy use, or operating reliability.
Controlled chambers are useful when engineers need to reproduce environmental conditions rather than rely on changing workplace or outdoor conditions. They support product evaluation, material testing, and comparison of system performance under defined levels of moisture, thermal state, and light exposure. Reproducible conditions make results easier to interpret and help reveal how environmental variation affects operation.
In HVAC design and building evaluation, engineers examine humidity, temperature, and illumination as part of the surrounding operating environment. These measurements help assess energy use, comfort-related conditions, system performance, and reliability within a workspace or building. Together, they provide engineering evidence for adjusting designs and evaluating whether a system maintains suitable, repeatable conditions.
