Marshall D. Sahlins, titan of anthropology, 1930–2021


Prolific scholar and activist remembered for academic influence and personal warmth
Marshall D. Sahlins, an eminent cultural anthropologist of the Pacific known for sparking lively academic debates, died April 5. He was 90.
Renowned for his prolific contributions to anthropology, Sahlins was the Charles F. Grey Distinguished Service Professor Emeritus at the University of Chicago. For decades, he studied the history and ethnography of communities in Hawaii, Fiji and other islands in the South Pacific during the period of European contact engaging his research with indigenous political structures, modes of kinship and conceptions of nature.
For Sahlins, anthropology was both a privilege and an adventure, offering an opportunity to “reproduce within one’s mind the way the world is put together for other people,” he said during a 2014 appearance at the Chicago Humanities Festival. ....

The universe is filled with magnetic fields. Understanding how magnetic fields are generated and amplified in plasmas is essential to studying how large structures in the universe were formed and how energy is divided throughout the cosmos.
An international collaboration, co-led by researchers at the University of Rochester, the University of Oxford, and the University of Chicago, conducted experiments that captured for the first time in a laboratory setting the time history of the growth of magnetic fields by the turbulent dynamo, a physical mechanism thought to be responsible for generating and sustaining astrophysical magnetic fields. The experiments accessed co ....
