The goal of this experiment is to determine and control the size, shape and stability of self-assembled discotic amphiphiles in water. For aqueous based supramolecular polymers such level of control is very difficult. We apply a strategy using both repulsive and attractive interactions. The experimental techniques applied to characterize this system are broadly applicable.

Accurately measuring temperature and water content of the upper 5 mm of the soil surface can improve our understanding of environmental controls on biological, chemical, and physical processes. Here we describe a protocol for manufacturing, calibrating, and conducting measurements with soil surface temperature and moisture sensors.

Nuclear Stability

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters. To hold positively charged protons together in the...

Drosophila fruit flies can distinguish small changes in temperature and therefore select environments with favorable thermal conditions. This video describes a behavioral assay that tests the temperature preference of Drosophila larvae on a linear thermal gradient.
FAQs
Solar heating supplies thermal energy, while atmospheric exchange can promote warming or cooling at the water surface. Water flow and circulation redistribute heat through the system, and contact with sediments can also alter how quickly temperatures change. The balance among these processes determines whether a river, lake, wetland, or coastal system warms or cools rapidly or remains relatively stable.
Water absorbs and stores heat, which can slow the immediate response of an aquatic system to changing environmental conditions. Circulation and mixing then redistribute that stored energy, while contact with air or sediments modifies warming and cooling rates. These interacting processes help explain why different water bodies, or different locations within one system, can experience distinct thermal patterns.
Temperature influences chemical reactions and dissolved oxygen, so thermal changes can affect the conditions available to aquatic life. Organism physiology also responds to temperature, making persistent or pronounced changes environmentally important. Evaluating stability therefore helps connect physical thermal conditions with habitat quality and with the possibility of thermal stress in rivers, lakes, wetlands, and coastal systems.
Assessment begins with measuring water temperature and examining how thermal conditions change within the system. Researchers can consider whether the water resists change and how it responds after warming or cooling influences occur, while interpreting the roles of solar heating, atmospheric exchange, flow, mixing, and sediment contact. The resulting evaluation supports judgments about habitat quality and thermal stress.
Measurements are useful when researchers need to assess habitat quality, identify thermal stress, guide restoration, or support water management. They can also help interpret long-term environmental change by showing how thermal conditions behave in rivers, lakes, wetlands, and coastal systems. Because temperature affects oxygen, chemistry, and organism physiology, the results provide environmental context beyond temperature alone.
Water temperature stability provides a thermal perspective for evaluating restoration choices and management conditions. Changes in resistance to warming or cooling, or in recovery after those changes, can help characterize environmental responses in aquatic systems. Over longer periods, temperature measurements also help interpret environmental change and compare the thermal condition of rivers, lakes, wetlands, and coastal areas.
