A study combining climate change records with fossil evidence of mammals in Africa reveals that times of erratic climate change are not followed by major upheavals in evolution.

The Arizona Board of Regents confirmed the appointments of Sama Alshaibi, Jean-Luc Brédas, Dr. Juanita Merchant, David Pietz and Dr. Donata Vercelli as Regents Professors.

A team of astronomers including researchers from the University of Arizona has discovered evidence of a giant planet in the process of forming. This provides the first-ever look at the earliest stages of the formation of a gas giant planet, when it's still embedded in the disk of gas and dust surrounding its young host star.

UArizona researchers were leaders in a worldwide effort to understand tropical trees and their futures under climate change. They found that heat and drought slow the growth of these trees, which are major carbon dioxide absorbers.

Jessica Tierney is a contributing author for the Intergovernmental Panel on Climate Change Sixth Assessment Report. She studies past climate change to help society better prepare for the future.

The Department of State's Diplomacy Lab gives college students the opportunity to present their recommendations on various topics. Two UArizona classes teamed up in the fall to participate in the program for the first time.

Chemistry instructor Colleen Kelley uses her imagination and knack for storytelling to make "boring" chemistry anything but. By disguising chemical elements as superheroes and turning chemical reactions into mysteries, her comics help fourth through sixth graders master chemistry concepts typically taught at the college level.

Joellen Russell uses floating robots, supercomputers and satellites to predict the global climate and carbon cycle, particularly the role of the Southern Ocean around Antarctica.
