This protocol introduces a method of cage change for rats via clicker training. Rats learn the desired behavior not only by direct training but also by observational learning. The implementation of this fast and easy protocol might help to improve well-being and hygiene in rodent facilities.

The current priority in breast cancer radiotherapy is to reduce cardiac doses without compromising target tissue coverage. The voluntary breath-hold technique described here is a simple, inexpensive solution to this problem and capable of being instituted widely without the need for specialized equipment.

Melting Land and Sea Ice ExpandNOTE: This activity is a simulation of land- and sea-ice melting and their effects on water levels. First, label one graduated cylinder as 'Sea Ice' and the other graduated cylinder as 'Land Ice.' Hypotheses: the experimental hypothesis might be that the land ice melting will cause the water level to rise more than the melting sea ice. The null hypothesis would be that there will be no difference in the change in water level between the two containers. Add 10 ice...

Climate Change - Concepts

2019
The certainty of climate change remains a public controversy despite the consensus among approximately 97% of active climate researchers, who not only agree that the Earth’s climate is changing but also state that this change is intensified by human activity, predominantly carbon emissions 1. The disconnect between the public and the experts is partly due to poor understanding of the mechanisms involved in climate change as well as the differences among essential concepts such as weather and...
FAQs
Animal-initiated movement can reduce the disturbance associated with being physically picked up, helping preserve activity, exploration, and social responses that may otherwise be altered by handling. This matters because behavioral observations are easier to interpret when the procedure itself introduces less stress-related disruption. The method therefore links husbandry refinement with more representative behavioral measurements.
Connected cages, tunnels, and similar routes create a continuous path between the home cage and the clean cage. Animals can begin movement and complete the transfer under their own control rather than being manually relocated. The route is therefore the central mechanism that makes voluntary movement practical while limiting the need for direct physical handling during cage change.
The main difference is how the animal is moved between cages. Physical pickup requires direct handling, whereas Voluntary Cage Change allows the animal to travel through a connected route without being picked up. This distinction can reduce handling-related disturbance and help behavioral researchers separate responses associated with the study from changes caused by routine husbandry.
A voluntary transfer may better preserve natural activity, exploration, and social responses by reducing the disturbance linked to forced handling. These behaviors are relevant indicators in behavioral research, so limiting procedural disruption can improve the consistency and interpretability of observations. The approach is especially useful when routine cage maintenance could otherwise influence the behavior being measured.
The essential setup uses a home cage, a clean cage, and a transfer route connecting them. That route may be a tunnel or another suitable connection that allows the animal to move between cages independently. The arrangement should support complete transfer under the animal’s control while providing a practical way to carry out routine husbandry.
During cage change, the home cage and clean cage can be connected so the animal moves through the available route rather than being physically picked up. Once the animal completes the transfer, the procedure provides a refined approach to routine maintenance. Its practical value comes from combining cage sanitation with reduced forced handling and less associated disturbance.
This approach is useful when researchers need routine husbandry to interfere as little as possible with behavioral observations. Reducing handling-related stress can help maintain more natural activity, exploration, and social responses, improving the consistency of recorded behavior. It also provides a welfare-oriented refinement for studies in which procedural disturbance could complicate interpretation of behavioral outcomes.
