A new technique that allowed researchers to analyze genetic material from serum samples of HIV patients taken before AIDS was known provides a glimpse into the beginnings of the epidemic.
A UA-led team finds that the four Kuiper Belt Objects with the longest known orbital periods revolve around the sun in patterns most readily explained by the presence of such a planet.
Grasslands and grass crops, covering much of the world's land area and providing half of the calories humans eat, may be unable to respond quickly enough to a changing climate that is outpacing the plants' ability to adapt.
How does natural selection result in evolutionary change? A new method that dramatically reduces the complexity underlying how genetic information is translated into traits could provide biologists with a key.

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.
