Tiny soil microbes are among the world's biggest potential amplifiers of human-caused climate change, but whether microbial communities are mere slaves to their environment or influential actors in their own right is an open question. Now research by an international team of scientists from the U.S., Sweden and Australia, led by University of Arizona scientists, shows that a single species of microbe, discovered only recently, is an unexpected key player in climate change. 

The findings, published in the journal Nature, should help scientists improve their simulations of future climate by replacing assumptions about the different greenhouse gases emitted from thawing permafrost with new understanding of how different communities of microbes control the release of these gases.

It's not every day that NASA scientists ask kids to design and launch rockets that could deliver food to inhabitants on a storm-ravaged, isolated Pacific island.

On Oct. 8, thousands of young students across the country took up that challenge as part of 4-H's 2014 National Youth Science Day. The event is held annually to encourage student involvement in STEM-related fields. Each year, 4-H'ers nationwide participate in the same science experiment.

"4-H is more than cows and cooking," said Kirk Astroth, director of Arizona 4-H Youth Development. "Everything we do is about science. We try to keep up with the changing needs and interests of kids – we teach app development, photography, GPS and rocketry."

The Arizona Board of Regents approved the University of Arizona’s request today to establish a Doctorate of Veterinary Medicine degree within the College of Agriculture and Life Sciences School of Animal and Comparative Biomedical Sciences. The program, which will cut the cost of educating Arizona veterinary students by half and provide a faster pathway to entering the workforce. The veterinary medical and surgical program plans to enroll its first students in less than one year.

The UA program will be founded on three critical pillars underpinning not only the veterinary profession but all of global society as it involves animals: commerce, human-animal interdependence and “One Health”—an approach to treating the health of humans, animals and the environment as interrelated. Not only will the program train DVMs, it will also allow students who do not become DVMs—but who are interested in a successful career in the very large and diverse areas of our economy associated with animals—to get a master’s degree in areas related to the three pillars.

As University of Arizona students partake in recreational sports at Bear Down Field, it's unlikely they realize what lies just beneath their feet. Under the north edge of the field lies a million-gallon tank designed to mitigate storm flows and harvest stormwater.

When monsoon clouds roll into town and unleash a downpour on the city, water is filtered into the tank, where it collects and, through a series of pipes, is directed outside of Likins residence hall, draining into the landscaping.

This tank is one of numerous water harvesting features integrated throughout the UA campus.
