Making cities naturally safe from supply chain shocks

A new paper in Nature lays out the way natural ecosystems parallel U.S. supply chains and how American cities can use these tools to strengthen their supply chains. The paper, “Supply chain diversity buffers cities against food shocks,” is co-authored by Benjamin Ruddell, director of the FEWSION Project and the School of Informatics, Computing, and Cyber Systems at Northern Arizona

Community health workers improve birthweight of newborns through the Arizona Health Start Program, researchers find

Researchers from Northern Arizona University and the University of Arizona found pregnant women and mothers who are treated by community health workers have lower rates of low birthweight and preterm newborns than their peers without those providers. The 10-year comprehensive study looked at women enrolled in Arizona’s Health Start Program, which employs community health workers (CHWs)

NAU geochemist on new study confirming cause of greatest mass extinction event

The most severe mass extinction event in the past 540 million years eliminated more than 90 percent of Earth’s marine species and 75 percent of terrestrial species. Although scientists had previously hypothesized that the end-Permian mass extinction, which took place 251 million years ago, was triggered by voluminous volcanic eruptions in a region of what

New study shows a few common bacteria account for majority of carbon use in soil

Image by Victor O. Leshyk, Ecoss Just a few bacterial taxa found in ecosystems across the planet are responsible for more than half of carbon cycling in soils. These new findings, made by researchers at Northern Arizona University and published in Nature Communications this week, suggest that despite the diversity of microbial taxa found in wild soils
