After a nearly 5,000-year vigil upon a Nevada mountaintop, an ancient tree now finds its home in the UA Laboratory of Tree-Ring Research. The Bristlecone pine, called Prometheus, is the oldest individual ever known to have lived.
Researchers have discovered four previously unknown viruses that infect the Earth’s most abundant organism, the marine bacterium SAR11, which play a critical role in the global cycle of carbon and other nutrients.
Experience from the HiRISE camera on the Mars Reconnaissance Orbiter in 3-D.
The UA has held a long-standing love for asteroids, from pioneering the search for potentially hazardous space rocks before NASA did to sending a spacecraft to one to scoop up a sample.

UA Science: A Place of Discovery and Innovation

Joaquin Ruiz, DeanThe University of Arizona College of Science brings together globally prominent faculty in disciplines at the core of scientific inquiry and education. One of the largest colleges at the University of Arizona, we are a nexus of award-winning programs that encourage both independent and collaborative-driven research. Our academic departments, schools and research units encompass the range of physical, mathematical, environmental, cognitive and life sciences. UA Science is among the most powerful and prolific academic research centers in the world, recognized and rewarded for the unparalleled caliber of our achievements. With over 7,500 undergraduate and graduate students, we are an integrative learning institution, where accomplished faculty and next-generation scientists engage side-by-side in groundbreaking research. Our scientists and students also share their knowledge with the local and broader community through extensive outreach and public service initiatives. Our mission is to encourage the aggressive pursuit of research excellence, to support novel teaching and outreach programs and to create economic opportunities for our community.

UA Paves Way to Redefine STEM Education
The UA, one of only eight sites in the nation chosen to participate in a major STEM education initiative, is innovating with course redesigns and unique faculty programs.
Evolutionary Biology: It's Not Just for Textbooks Anymore
UA scientists, including entomology expert Bruce Tabashnik, are on the leading edge of an approach to tackle global challenges in food security, emerging diseases and biodiversity loss.
Asian Monsoon Much Older Than Previously Thought
Scientists originally thought the climate pattern, which brings torrential summer rains and dry winters, began 22-25 million years ago as a result of the uplift of the Tibetan Plateau and the Himalaya Mountains. But UA researchers say that's not going back far enough.
Interactions of Earth’s Smallest Players Have Global Impact
A new study reveals the interactions among bacteria and viruses that prey on them thriving in oxygen minimum zones, stretches of ocean starved for oxygen that occur around the globe. The UA's newly launched Ecosystem Genomics Institute is dedicated to the researching such microbial communities in their natural environments as an important step in understanding global processes including climate.
Meteorite That Doomed Dinosaurs Remade Forests
The impact decimated slow-growing evergreens and made way for fast-growing, deciduous plants, UA researchers say, and that provides an explanation for those fall colors.
