Statistics show relatively high usage rates for UArizona's exposure notification app, which helped curb the spread of the virus on campus. Public health experts say the digital strategy worked well because it was used in conjunction with traditional contact tracing, in addition to testing and isolation efforts.

A grant from the National Science Foundation will help the University of Arizona train the next generation of interdisciplinary scientists who can "scale across genes to ecosystems" to understand how wild and agricultural systems function and respond to change.

With $2.5 million from the National Science Foundation, a national team of collaborators, including researchers at the University of Arizona, aims to harness the power of big data to predict the fate of global biodiversity in the wake of environmental change.

A new diagnostic test for coronavirus relies on gargling with saltwater instead of using a nasal swab. Initial results have been encouraging, UArizona virology expert Michael Worobey says.

Tropical forests may be more resilient to climate change than previously thought, according to a new study.

While many of us have been working from home this summer, a secretive activity has been going on in full swing across campus: Several species of insects and plants have been acting out fascinating plays of interactions and mutual interdependence.

Molecular clock analysis showed no widespread community distribution of the highly contagious coronavirus disease in Arizona until mid-February.

A new study combines evolutionary genomics from coronavirus samples with computer-simulated epidemics and detailed travel records to reconstruct the spread of coronavirus across the world in unprecedented detail.

University of Arizona researchers studied the evolution of the body sizes of frogs and their tadpoles. They found that the two life stages do not evolve completely independently of each other as previously thought.

The evolution of colorful feathers shines light on the missing link in evolution by natural selection, according to new University of Arizona research
