This video is composed of a sequence of time lapse films created by John Tyler Bonner in the 1940s to show the life cycle of the cellular slime mold, Dictyostelium discoideum. As only the second person to study slime molds, Bonner frequently encountered audiences who had never heard of, let alone seen, the unusual organism. He therefore decided to create a film to present at seminars in order to introduce his object of study. Bonner created the video for his senior thesis at Harvard University with the help of photographer Frank Smith. Bonner began to work at Princeton University in 1947, thus the mention of that university on the title screen of the film. It was digitized and narrated by developmental biologist Rachel Fink of Mount Holyoke College. Includes (approximate starting times given): Amoebae [00:02]; Aggregation [00:27]; Migrating Pseudoplasmodia [02:16]; Culmination [03:28]; Trisected Pseudoplasmodium [04:17].

By the 1930s, the MBL had become "the" place to go during the summer for biological research and training. Luminaries such as Frank Lillie, Edmund Beecher Wilson, Edwin Grant Conklin, and Thomas Hunt Morgan took their students, packed up their families and research labs, and headed to the MBL. They worked in labs, ate together in the Mess, and they often lived in the limited on-campus housing. Life at the MBL was a life where fun, family, and science intertwined. This film, taken in 1935 by B. R. Coonfield of Brooklyn College, captures snippets of life at the MBL. Though the science and equipment are considerably updated and the faces and families have changed, many features remain the same today.

Agricultural and dairy work is among the most dangerous work in the US. In addition to the dangers of work, undocumented migrant workers may face additional stress as a result of the increase in antiimmigration enforcement and criminalization of undocumented status. The purpose of the study was to better understand how migrant dairy workers were impacted by the increase in restrictive immigration policies and immigration enforcement, as well as how they coped with any issues they faced. Interviews were conducted with fourteen migrant dairy workers following the passage of several anti-immigration bills across the US. Findings revealed four major categories; three were related to negative impacts of immigration policies and enforcement:

1. Fear.
2. Stress and anxiety.
3. Perceptions of discrimination.

An additional major category emerged that demonstrated the hope and resilience of participants in the face of an increasingly difficult socio-political environment. Implications for social service practice, policy, and research are discussed.

The purpose of this paper was to examine the impact of perceived discrimination among Latino immigrants in the context of recent immigration policies and immigration enforcement strategies. Data for this study were drawn from a pilot study (n=213) of adult Latino immigrants living in Arizona during the summer of 2014. The results of multivariate OLS linear regressions indicated greater perceived discrimination was significantly related to reporting:

1. Avoidance of immigration officials.
2. Family has suffered.
3. Friends have suffered.

In addition, greater perceived discrimination was significantly related to lower confidence in a better future for the individual, their families, their children, and the children of today.
