On Sonic Sovereignty

Dr. Dustin Tahmahkera discusses indigenous sound in HI’s Faculty Fellows Seminar on Health, Well-Being, Healing
By Saralyn McKinnon-Crowley

At last week’s Faculty Fellows Seminar, Dr. Dustin Tahmahkera (Mexican American and Latina/o Studies) discussed his work-in-progress, “Sounds Indigenous” or “Becoming Sound.” Dr. Tahmahkera employs “sound” in its dual meaning, as both auditory stimulus and as wellness or health. His project asks three questions:

  • What are the roles of sounds in indigenous and American cultural histories and identity formations, historically and today?
  • How do we listen to ways of sounding indigenous?
  • How can sound heal and impact the well-being of individuals, communities, and the land?

Our Contaminated World

Dr. David Crews presents lessons from biology in HI’s Faculty Fellows Seminar on Health, Well-Being, Healing
By Saralyn McKinnon-Crowley

At this week’s Faculty Fellows Seminar, Dr. David Crews (Integrative Biology) spoke about the mutual interdependence of the environment and human biology. Dr. Crews argued that the environment is permanently contaminated by the mass production of synthetic chemicals and other factors, and it is now impossible to return it to pre-Industrial Revolution conditions. Biological effects from human exposure to these chemicals can occur generations after the initial encounter (a process known as synchronicity). The impact of these chemicals can be seen beyond gene expression and, indeed, extends to human psychological and emotional responses. To illustrate these changes, Dr. Crews used the example of endocrine disrupters (EDCs)—chemicals that disrupt the collection of glands that secrete hormones into the circulatory system to be carried to target organs.

Dr. Crews specifically discussed one type of EDC, polychlorinated biphenyls (PCBs), man-made chemicals used widely in industrial and commercial products . Even though the industrialized world ceased use of PCBs in the 1970s, PCB levels are still present in organisms today and have even been found in the Arctic Circle.
