Ethics in Research01:56

Ethics in Research

23.0K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Mechanism of heat transfer01:19

Mechanism of heat transfer

1.2K
Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Zeroth Law of Thermodynamics01:14

Zeroth Law of Thermodynamics

5.1K
Experimentally, if object A is in equilibrium with object B, and object B is in equilibrium with object C, then object A is in equilibrium with object C. That statement of transitivity is called the "zeroth law of thermodynamics." For example, a cold metal block and a hot metal block are both placed on a metal plate at room temperature. Eventually, the cold block and the plate will be in thermal equilibrium. In addition, the hot block and the plate will be in thermal equilibrium.

Temperature and Thermal Equilibrium01:11

Temperature and Thermal Equilibrium

6.7K
Heat and temperature are essential concepts for everyone every day. The study of heat and temperature is part of an area of physics known as thermodynamics. It is not always easy to distinguish heat and temperature.
The concept of temperature has evolved from the common concepts of hot and cold. The scientific definition of temperature explains more than just our sense of hot and cold. Temperature is operationally defined as the quantity measured with a thermometer. Furthermore, temperature is...

Thermosensation01:43

Thermosensation

30.4K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Summary
This summary is machine-generated.

Standard housing temperatures overactivate mouse metabolism, potentially skewing research results. Maintaining mice within their thermoneutral zone is crucial for animal welfare and data relevance in scientific studies.

Area of Science:

  • Physiology
  • Animal Models
  • Metabolism

Context:

  • Mice, a common animal model, are endothermic mammals housed at 22°C.
  • This ambient temperature overactivates their energy metabolism, unlike in humans with thermoregulatory adaptations.
  • The thermoneutral zone is key for minimizing thermoregulatory effort.

Purpose:

  • To highlight the impact of housing temperature on animal models.
  • To emphasize the discrepancy between standard housing and thermoneutral conditions.
  • To advocate for considering housing temperature in research.

Summary:

  • Standard housing at 22°C leads to overactivated energy metabolism in mice.
  • Divergent research outcomes are observed between 22°C and thermoneutral (30°C) conditions.
  • Housing temperature significantly affects animal welfare and experimental validity.

Impact:

  • Informs researchers on optimizing animal model conditions.
  • Improves the reliability and reproducibility of scientific findings.
  • Promotes better animal welfare practices in research settings.
