The Lindo lab specializes in mapping little-explored human lineages of the Americas.
Previously published research found evidence of the tuberculosis bacterium in the skeletal material of 1,400-year-old Andean mummies, contradicting some theories that TB did not exist in South America until the arrival of Europeans 500 years ago.
The current paper provides the first evidence for a human immune-system response to TB in ancient Andeans and gives clues to when and how their genomes may have adapted to that exposure.
Among the strongest signals detected were for biomarkers that are switched on in modern humans during an active TB infection. The researchers modeled the timing of selection for several of the genes involved in the TB-response pathways. Although they were not as strong as for exposure to TB, some signals were also detected for biomarkers related to adaptation to hypoxia, or low levels of oxygen in the blood that result from living at high altitude.
“Human-pathogen co-evolution is an understudied area that has a huge bearing on modern-day public health,” Sophie Joseph says. “Understanding how pathogens and humans have been linked and affecting each other over time may give insights into novel treatments for any number of infectious diseases.”
“Selling Industrial ‘Gallina Criolla’ Products in Guatemala” details these new corporate marketing tactics of competing with gallina criolla economies of indgenous and peasant peoples. The report begins by summarizing the latest science on the economic, ecological, social, nutritional, and taste differences between gallina criolla and industrial chicken. It shows that the gallinas criollas that emerge from campesina systems of production are different animals than the industrial chickens that emerge from industrial systems of production. The methods of rearing involved, the ecological and economic functions the birds perform, and the nutritional value and taste of the chicken meat from the two systems are not the same. At the same time, while gallina criolla production is one part of agroecological systems that tend towards diversity, industrial production of commercial chickens tends towards homogeneity.
Lori Jahnke, the Department of Anthropology librarian, and her colleagues at the New Jersey Institute of Technology, University of Iowa, and researchers at Fiocruz will share a three-year grant from the National Science Foundation aimed at responsible management of scientific collections created under unequal power dynamics. Jahnke and her colleagues plan to establish and test a methodology for collaborative, community-based work to document and understand subjects’ experience of scientific research and the afterlives of scientific objects that are produced. The project will help researchers reevaluate assumptions about data collection, their methodologies, intellectual property and knowledge production.
Marcela Benítez (Emory University, Emory College of Arts and Sciences, Department of Anthropology) and Jacob Abernethy (Georgia Tech, School of Computer Science) were recipients of the AI.Humanity Seed Grant Program. They were awarded $100,000 in funding towards their proposal to develop and implement “smart” testing stations using artificial intelligence (AI) for long-term cognitive assessment and monitoring of wild capuchin monkeys at the Toboga Forest Reserve in Costa Rica.
SJ Dillon has been awarded the National Science Foundation’s Graduate Research Fellowship for their dissertation research into gender dysphoria. They will will provide an ethnographic account of a diverse group of trans communities in contemporary Atlanta, Georgia, and will compare discourses on gender dysphoria in national medical and state-level legal discourses to that ethnographic data.
Hunter Akridge is one of 16 Beincke Scholars nationwide. He has received the Department of Anthropology’s Outstanding Junior Award and the Trevor E. Stokol Scholarship for undergraduate research. Find more details on his research in the Emory News article.
The research found different and previously undetected ancestry in a man and a woman dating back 800 and 1,500 years, both from an archeological site in eastern Uruguay. This supports the theory of separate migrations from North America into different areas in South America. “We’ve now provided genetic evidence that this theory may be correct,” Lindo tells Phys.org.
Ruşen Bingül, a second-year Ph.D. student, has been awarded the American Ethnological Society (AES) Field Grant and the Halle Institute Global Research Fellowship for her summer doctoral research fieldwork. Both grants are for students who are in the pre-candidacy and whose projects involve ethnographic field research in anthropology or allied fields. Ruşen will use these grants for her summer fieldwork from May 15 to August 20, focusing on legal pluralism and alternative justice mechanism among Kurds in Mardin, the Kurdish Region of Turkey.
