Michael Kotutwa Johnson leads a project at the University of Arizona Campus Agricultural Center that involves low-cost irrigation trials, nutritional analysis of traditional crops and the development of databases to capture the science of Indigenous agricultural systems.

Built with mirrors manufactured by the University of Arizona, one of the world's largest optical telescopes clears key milestone toward U.S. federal construction support.

According to researchers at the University of Arizona and The University of British Columbia, small-scale observations of how plants respond to heat don't always translate into an accurate prediction at a larger scale.

The new program will allow graduating physicians from the U of A colleges of medicine to enter the workforce one year earlier than those who pursue the traditional four-year degree.

The U of A earned its best ranking in the space science category, rising four spots to No. 4 globally and No. 2 among U.S. public universities.

New observations of 30 planet-forming disks – the birthplaces of planets around stars – reveal in greater detail than ever how gas and dust behave over time and shape the evolution of exoplanet systems.

As the Colorado River carved the Grand Canyon, it flushed away ancient groundwater. The discovery was made using a new method that determines the age of water based on how much of the radioactive element krypton-81 is present.

Amid the call for drastic water-use reductions in the Southwest, Arizona agriculturists, scientists and water stakeholders will gather to explore future sustainability at the Water Resources Research Center annual conference.

In many cases of epilepsy – which disrupts electrical activity in the brain and often results in seizures – the underlying cause is unknown. UArizona researchers may have found an explanation for some forms of epilepsy.

A concept developed by UArizona aerospace experts and a NASA planetary scientist takes inspiration from albatross flight to learn more about the Red Planet's atmosphere and geology.
