In this video, we perform a clonogenic assay of keratinocytes harvested from adult mice to determine the ability of individual cells to proliferate and form colonies. This keratinocyte harvesting technique is useful for studying other downstream aspects of cutaneous chemical carcinogenesis and tumor promotion.

Substantial Boom in the Housing Market

Following the dot-com collapse and the September 11 Attacks, the United States entered a brief recession in 2001. In response, the Federal Reserve implemented a highly accommodative monetary policy to stimulate economic recovery. Short-term interest rates were aggressively reduced. This sharp decline in borrowing costs significantly affected the housing market by making mortgage loans far more affordable.When banks faced lower short-term borrowing costs from the Federal Reserve, they were able...

Repercussions of the Fall in Housing Prices I

2026
The U.S. housing market began to weaken in 2006 after many years of rising home prices. During the housing boom of the early and mid-2000s, home construction increased rapidly. This increased the housing supply, but demand did not keep pace. As supply exceeded demand, housing prices began to fall.The decline in home values created serious problems for homeowners. Many had taken out large loans to purchase homes when prices were high. As home prices dropped, many homeowners became “underwater,”...

Repercussions of the Fall in Housing Prices II

2026
In 2006, housing prices in the United States began to decline.As housing prices fell, the repercussions extended far beyond homeowners, undermining the stability of financial institutions. Many financial institutions had invested heavily in mortgage-backed securities, which depended on mortgage payments made by homeowners. As long as homeowners continued making payments, these financial assets retained their value.However, many homeowners, especially those with subprime mortgages, stopped...

Dominance relationships can alter how animals interact, compete, and respond to one another. Because these relationships emerge alongside social recognition and communication, observed behavior may reflect both individual responses and position within the group. Recording affiliative behavior, aggression, and stress responses therefore helps researchers distinguish general group effects from behavior associated with social organization.
Group composition, enclosure size, population density, resource availability, and environmental enrichment are central variables. These conditions shape opportunities for social contact, competition, cooperation, and adaptation to the group environment. Compatibility and appropriate density are especially important because poorly managed combinations may increase conflict, whereas suitable conditions can support welfare and produce behavioral observations that are more consistent.
Social recognition helps animals respond to group members and participate in communication, cooperation, or competition. In a colony, these processes contribute to social organization and dominance relationships, which can influence affiliative behavior, aggression, and stress responses. Measuring these outcomes gives behavioral studies a way to examine how group living shapes interactions rather than treating animals as isolated subjects.
Before observation, researchers should consider enclosure size, group composition, population density, resource availability, and environmental enrichment, then assess compatibility among animals. These decisions establish the social conditions under which behavior will be measured. Maintaining suitable density and minimizing incompatible groupings can reduce conflict, support welfare, and limit housing-related variation that could otherwise complicate interpretation and reproducibility.
Colony housing can support investigation of social organization, affiliative behavior, aggression, stress responses, and adaptation to group environments. These outcomes capture both positive and adverse aspects of social interaction, allowing researchers to examine cooperation, competition, and responses to changing social conditions. The observations are particularly useful when the research question concerns behavior that depends on interaction among animals.
Because housing conditions can alter social interactions, they can also alter measured behavior. Managing density, compatibility, enclosure features, resources, and enrichment helps create more comparable group environments across studies. At the same time, colony housing can better reflect natural social behavior than an isolated setting, improving the relevance of findings while reducing variation caused by unmanaged conflict or unequal conditions.
