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.

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...

The Thoracic Cage: Sternum
0 Views •
2023
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12). The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid process.
FAQs
Replacing soiled bedding and removing waste helps regulate moisture, odors, and ammonia within the enclosure. Sanitized equipment further limits the buildup of contaminated materials and potential pathogen exposure. By keeping these conditions more stable, the practice supports animal welfare and reduces environmental variation that could otherwise affect biological observations.
These conditions indicate changes in the cleanliness and stability of the housing environment. Excess moisture, persistent odors, or ammonia associated with soiled materials can contribute to less suitable enclosure conditions and may increase concerns about animal health or comfort. Cage changing addresses these factors through waste removal, fresh bedding, and equipment sanitation.
Frequency should be appropriate for maintaining cleanliness, animal welfare, and stable experimental conditions. Changing too infrequently can allow soiled materials, moisture, odors, and ammonia to accumulate, while inconsistent timing can introduce environmental variation between animals or study periods. A suitable routine therefore supports both humane care and dependable research conditions.
Consistent cage-changing practices reduce avoidable differences in housing conditions across animals and experimental sessions. More stable levels of cleanliness, moisture, odors, ammonia, and potential pathogen exposure can reduce environmental influences on behavior, physiology, and biomedical measurements. This makes observed outcomes more likely to reflect the study rather than changing enclosure conditions.
The routine begins by transferring the animals to a clean cage or suitable temporary enclosure. Used bedding, waste, and other contaminated materials are then removed. Fresh bedding is added, and equipment is sanitized before the animals return to the maintained enclosure. Performing these steps consistently helps preserve cleanliness and stable housing conditions.
It is especially important in studies that measure behavioral, physiological, or biomedical outcomes, because housing conditions can influence these observations. Reliable maintenance also supports humane animal care by reducing disease risk and environmental deterioration. Applying the same appropriate technique and frequency across the study helps researchers interpret results with greater confidence.
