EPICS Lakota: Promoting Food Sovereignty on Pine Ridge Indian Reservation

EPICS Team Lakota was started as a way for students to help promote food sovereignty and combat loss of cultural knowledge as felt by the residents of Pine Ridge Reservation, which is located in one of the poorest counties in the United States and is a food desert. In partnership with EPICS students at Oglala Lakota College (OLC) and South Dakota School of Mines (SDSM), students at Purdue came up with the idea of putting up a greenhouse on the Rapid City Campus of OLC. This greenhouse was meant not as a direct solution to food scarcity, but as a blueprint to be implemented across the reservation in the future. The greenhouse will be a resource for students, teachers, residents, and community elders to come together and preserve the knowledge of culturally significant plants and herbs, as well as a place to learn how to grow the fresh produce that is so hard to find on the reservation. Students at all schools worked together to figure out the optimal size and construction of the greenhouse, and also worked with residents to determine what should be grown and how to meet the needs of each plant. Consideration was given to the sustainability of the project as this was important to the Lakota stakeholders, including ways to lighten the load on any water and electric utilities. The greenhouse was also designed to be ADA accessible, so that community elders and all who needed such accommodations would have no trouble taking part. Throughout the project, students kept in contact with each other and the affected community. This continuous communication both aided and impeded the progress of the project. Care was taken at each point in the project to make sure that the final deliverable was the most effective it could be. This paper will explore the successes of the project and how the students addressed concerns as they arose

Spatiotemporal Regulation of Cell–Cell Adhesions

Cell–cell adhesions are fundamental in regulating multicellular behavior and lie at the center of many biological processes from embryoid development to cancer development. Therefore, controlling cell–cell adhesions is fundamental to gaining insight into these phenomena and gaining tools that would help in the bioartificial construction of tissues. For addressing biological questions as well as bottom-up tissue engineering the challenge is to have multiple cell types self-assemble in parallel and organize in a desired pattern from a mixture of different cell types. Ideally, different cell types should be triggered to self-assemble with different stimuli without interfering with the other and different types of cells should sort out in a multicellular mixture into separate clusters. In this chapter, we will summarize the developments in photoregulation cell–cell adhesions using non-neuronal optogenetics. Among the concepts, we will cover is the control of homophylic and heterophilic cell–cell adhesions, the independent control of two different types with blue or red light and the self-sorting of cells into distinct structures and the importance of cell–cell adhesion dynamics. These tools will give an overview of how the spatiotemporal regulation of cell–cell adhesion gives insight into their role and how tissues can be assembled from cells as the basic building block

Freshwater is one of Earth’s most precious resources and is now increasing in scarcity. Global warming induced climate change is now changing rain patterns and causing record drought, growing global populations are increasing demand, and the individual demand per person is increasing and human populations urbanize and adopt modern plumbing. The biggest contributor to increasing demand for water is mismanagement and pollution. However for this project we will be focusing on water quantity rather than quality.Deliverable
