New research finds that sexual reproduction and multicellularity drive diversity among different species.
New UArizona-led research identifies climate change challenges faced by U.S. Department of Defense facilities, and solutions that might serve as a model for other large organizations.
The study will help researchers better understand how difficulties in romantic relationships affect mental health, well-being and risk for depression.
UArizona is providing the software hub for the NEID spectrometer on Kitt Peak as the instrument begins its mission to discover Earth-like planets elsewhere in the Milky Way.
Researchers used detailed observations of an enormous jet of glowing gas and dust to pinpoint the supermassive black hole at the center of galaxy Centaurus A.
Runoff from melting snow is an essential water resource for many communities and ecosystems, but when snow melts too rapidly in a short time, it can be destructive. To better understand the processes that drive such melting, researchers mapped extreme snowmelt events over 30 years.
Synthetic chemicals known as PFAS not only pose a long-term threat to groundwater quality, but also a long-term challenge to scientists tasked with cleaning them up.
An ancient coronavirus outbreak in East Asia could help researchers identify viruses that have caused epidemics in the past and may do so in the future.
An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn's moon Enceladus, suggests a new study co-authored by UArizona scientist Régis Ferrière.
