In this video article, we describe a new method allowing the construction of odorant gradients with stable and controllable geometries. We briefly illustrate how these gradients can be used to screen for olfactory defects (full and partial anosmia) and to study more subtle features of chemotaxis behavior.

Group Behavior - Concepts

Life in a Population Organisms in populations interact with one another in complex ways, where individuals compete for resources such as food, shelter, and mates. These interactions are costly since individuals invest energy to acquire the resource, therefore there are a variety of strategies that organisms adopt to gain an advantage over their competitors. This is observed clearly with polymorphic mating systems, in which one sex, predominantly males, display multiple mating strategies. For...
FAQs
Fluid behavior is strongly shaped by viscosity and density, but they affect systems in different ways. Viscosity influences how readily a fluid moves, whereas density contributes to how the fluid responds during motion and under applied forces. Engineers consider both properties when predicting transport, evaluating pressure-driven flow, and developing designs intended to limit energy losses.
Pressure gradients, gravity, and surface interactions can either drive or constrain fluid motion. A pressure difference may promote transport through a system, while gravity and boundary effects alter how the fluid moves within that system. Considering these influences together helps engineers interpret changes in flow and assess how system boundaries affect performance.
Laminar and turbulent flow represent different movement conditions that can produce different engineering outcomes. Laminar motion is smooth, while turbulent motion is irregular. Identifying which condition occurs helps engineers evaluate transport, energy losses, and system performance. This distinction is important when designing pipelines, cooling systems, and other technologies in which flow quality affects efficiency.
Energy losses indicate that part of the available energy is not being used for the intended transport or motion. Fluid properties, applied forces, and the resulting flow condition all contribute to how engineers evaluate these losses. Accounting for them supports more efficient designs for pipelines, pumps, turbines, and cooling systems, while also helping engineers assess performance limitations.
Engineers begin by considering the fluid properties, including viscosity and density, then examine pressure gradients, gravity, surface interactions, and system boundaries. They determine whether the conditions produce smooth or irregular flow and evaluate the resulting energy losses. This analysis provides a basis for predicting performance and refining designs for transport, motion, heat transfer, or mass transfer.
Applications span pipelines, pumps, turbines, aircraft, cooling systems, and microfluidic devices. In each case, engineers use fluid analysis to understand motion, transport, and the effects of pressure or boundaries. The same principles support very different scales and functions, from moving fluids through infrastructure to controlling flow in compact devices.
Fluid motion affects how heat and mass move through an engineering system. By examining properties, driving forces, boundaries, and flow conditions, engineers can evaluate transport behavior and identify factors that influence performance. This context is especially relevant to cooling systems and other technologies where effective transfer contributes to operation, efficiency, and design optimization.
Understanding fluid motion allows engineers to predict how systems respond to pressure, gravity, boundaries, and changing flow conditions. They can then evaluate energy losses and optimize performance before applying designs in technologies such as pumps, turbines, pipelines, aircraft, and cooling systems. These analyses contribute to safer operation and more efficient use of engineering systems.
