World Water Day is March 22, but at the U of A – ranked No. 1 in the U.S. in water resources by ShanghaiRanking Global Ranking – water is at the center of rigorous research year-round.

A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, a new study finds.

The research team, which included University of Arizona planetary scientists, used data from NASA's Transiting Exoplanet Survey Satellite, or TESS, to study young sub-Neptunes — planets bigger than Earth but smaller than Neptune — that orbit close to their stars.

Neuroscientists have found that aging alters the gene expressions that control birds' songs. The finding could lead to better treatments for disorders such as Parkinson's and Alzheimer's.

NASA's newly launched SPHEREx mission will use software developed at the Arizona Cosmology Lab to analyze data and help astronomers understand what happened in the first trillionth of a second after the Big Bang.

The annual Cozzarelli Prize acknowledges papers that reflect scientific excellence and originality.

U of A astronomers are learning more about a galaxy that existed when the universe was just 2% of its current age. One unexpected finding: significant amounts of oxygen.

A new study sheds light on how extreme weather events impact phenological processes, specifically the flight period of butterflies and moths and the flowering time of plants, with implications for food security in the wake of climate change.

The U of A's physical sciences programs are ranked 50th in the world and 11th among U.S. public colleges and universities in Times Higher Education's World University Rankings by Subject.

An advanced imaging system developed at the University of Arizona boasts a shape-shifting mirror that delivers observing details typically reserved for space-based telescopes.

Researchers at the University of Arizona have discovered that planet-forming disks of gas and dust around tiny stars live much longer than previously thought. The findings provide new insights into planet formation and the habitability of planets outside our solar system.
