A set of 80 unplayed tapes buried in the archives at Northern Arizona University turned out to be a series of never-before-heard interviews with Holocaust survivors who settled in the United States. Thanks to an archivist, one professor and a handful of student workers, the interviews will be digitized, transcribed and added to the permanent collection of the United States Holocaust Memorial Museum.
New research from Northern Arizona University shows that the evolution of fruit鈥攁nd the evolution of fruit-eating primates, the early ancestors of humans鈥攚as influenced by the 鈥渆cosystem engineering鈥� of large sauropods.
Researchers and land managers have long known that reducing the amount of forest fuel helps reduce wildfire severity. But not all fuel is created equal, and the vertical location of that fuel may matter more than the sheer amount, especially when weather conditions are hot, dry and windy. Recent research from NAU, using data collected from NASA spaceborne lidar, shows that large-scale maps of ladder fuels can help predict areas at greatest risk from wildfires and suggests that a focus on reducing ladder fuels may be the most direct means to reduce wildfire severity.
New research published in Science shows that in 2024, Earth surpassed 1.5 degrees of warming鈥攖he threshold world leaders hoped not to cross when they signed the Paris Agreement. Now, Earth is hurtling toward a 2.7-degree increase by 2100. Why did we overestimate our abilities? Part of the answer lies in the Arctic, a region that鈥檚 warming faster than scientists expected.
Why did banks lend out less money during the Great Recession? Economists have claimed it鈥檚 because instead of lending, banks bought Treasuries, or U.S. government debt, because they鈥檙e less risky than lending to businesses and people in economically shaky times. But a researcher and onetime Wall Streeter now claims the blame lies in part with the Federal Reserve鈥檚 2008 decision to pay interest on banks鈥� excess reserves.
The study, led by the International Union for Conservation of Nature and co-authored by experts throughout the world, recommends targeted action to prevent further extinctions and calls for governments and industry leaders to use these data in water management and policy measures to protect critical species and ecosystems.
New research co-authored by Northern Arizona University scientists examines the global risks posed by a shrinking Great Salt Lake and looks at the economic and environmental solutions needed to refill it.
New research led by Northern Arizona University showed that it鈥檚 not if, but when we will see pan-resistance.
First-year Ph.D. student Samantha Hemmelgarn led a study that looked at "footprints"鈥攖hose meteor showers we see occasionally in the night sky鈥攐f comets that haven't passed Earth in 200 years to determine where those comets are now and, importantly, whether any of them are on an impact path with our planet.
Even in extreme heat waves, Fremont cottonwood trees can cool themselves through evaporation in their leaves, similar to the way we sweat when we鈥檙e hot. It鈥檚 how they鈥檝e survived in Arizona and throughout the Southwest.
Scientists across four continents worked together to create and analyze three-dimensional maps of tropical rainforests throughout the globe. What they found is worrying: three- quarters of rainforests worldwide are suffering from human intervention, endangering thousands of animal species and threatening delicate ecosystems that are crucial to human survival.鈥�
Teams from Northern Arizona University and the Salt River Project collaborated on several research projects, including ones aimed at protecting the Salt and Verde River watersheds and ensuring the power grid can handle the increasing number of electric vehicles on the road.
The launch of the Treatment and Wildfire Interagency Geodatabase, known as TWIG, now provides an open-access platform where all federal fuel treatment and wildfire data can be viewed, downloaded and analyzed. This comprehensive data compilation enables users to assess, plan and monitor fuel treatment interactions with wildfires across boundaries.
Researchers' analysis of 鈥渇ound鈥� lidar data from a completely unstudied corner of the Maya civilization revealed countless settlements that archaeologists never knew about. The study demonstrates, once and for all, that there鈥檚 still plenty of the Maya world to uncover.
Kevin Gurney, a professor from NAU鈥檚 School of Informatics, Computing, and Cyber Systems, found that a global database co-founded by Gore was underestimating greenhouse gas emissions at power plants by an average of 50%.
Homelessness in Arizona has reached a new crisis point. In 2023, more than 14,000 people were without shelter鈥攁 29% increase since 2020.Help could be on the way, thanks to grant funds that are fueling new research projects based at NAU and developed alongside community partners.Laura Noll and Robert Wickham, both associate professors of psychological sciences at NAU, recently received more than $1 million in grants from the Garcia Family Foundation to lead three projects aimed at not only finding housing and support for unsheltered Arizonans but also preventing future homelessness in the state.
