For much of the past century, the invasive pink bollworm wreaked havoc in the southwestern United States and northern Mexico. A multifaceted strategy eradicated the pest from cotton-producing areas of the region according to a new study led by Regents professor, UArizona Entomology department head, and BIO5 member, Dr. Bruce Tabashnik. According to the study, the eradication program saved U.S. cotton growers $192 million from 2014 to 2019. Through environmentally friendly approaches, it also helped to reduce insecticides sprayed against all cotton pests by 82% and prevented the application of over a million pounds of insecticides per year in Arizona.

The NASA Astrobiology Program has selected eight new interdisciplinary research teams to inaugurate its Interdisciplinary Consortia for Astrobiology Research program, including two teams at the University of Arizona. One team led by Dr. Betül Kaçar, Molecular and Cellular Biology assistant professor and BIO5 member, was selected from a pool of more than 40 proposals. The breadth and depth of the research of these teams spans the spectrum of astrobiology research, from cosmic origins to planetary system formation, origins and evolution of life, and the search for life beyond Earth.
