On a planet that just hit an atmospheric carbon concentration of 415 ppm, accurately predicting where the carbon is going in the future has never been more important.

Much of what we know about where carbon will be on the globe in 12, 25 or 100 years is due to innovative predictive modeling tools like the ones researcher Yiqi Luo develops at Northern Arizona University’s Center for Ecosystem Science and Society (Ecoss). Many carbon cycle models, or computer programs that run equations to… Read more

Every day, Americans rely on engineered systems such as bridges, buildings and offshore structures that are subject to extreme weather, earthquakes and a range of other conditions. Knowing how materials used in these systems respond to stressors is crucial to creating components that successfully and efficiently do the job.

Engineers rely on mathematical models to predict how the materials they use will react to stressors. However, some “state-of-the-art” models for ductile metals that have been in place for years have done an inadequate job… Read more

When it comes to wildfire, where a forest stores its carbon matters. Older, larger trees store more carbon in their wood and leaves than younger, smaller trees—and when they burn, those older trees release more carbon into the atmosphere that is harder to replace.

But in the United States, most forest management policies don’t account for the elevated risk large, hot fires pose to those older trees, researchers from the University of New Mexico, the U.S. Forest Service and the Center for Ecosystem… Read more

Northern Arizona University will begin offering a bachelor’s degree in health sciences at NAU Yuma beginning in fall 2020. NAU’s B.S. in Health Sciences program is offered online in a 90/30 format where students can transfer up to 90 credits from applicable community college programs into the degree completion program at NAU. Students then complete their bachelor’s degree with 30 credits at NAU. Beginning in fall 2020, NAU Yuma will host an on-site program for this degree which has shown high student demand statewide,… Read more

Since the mid-20^th century, the global human population has grown from 2.5 billion to 7.7 billion, according to the most recent United Nations estimate. Much of this growth was due to the unprecedented agricultural expansion made possible by the widespread use of synthetic pesticides starting in the 1950s.

By applying pesticides to prevent a variety of insects, rodents and birds from damaging crops, farmers increased productivity by between 20 and 50 percent and maximized the benefits of other valuable agricultural tools, such as high-quality seeds, fertilizers and… Read more
