A new U of A-led study combines data from ancient shells with advanced climate modeling to shed light on how El Niño weather patterns might change in a warming world.

Tree-ring data reveal that periodic shifts in strong winds high above Earth's surface have driven opposite climates in different parts of Europe for at least the past 700 years.

In the Best National Universities ranking, the U of A tied for No. 109 overall and tied for No. 52 among public universities – a six-spot increase for both. The university ranks No. 12 among colleges and universities designated as Hispanic-Serving Institutions and No. 23 among state flagship universities.

U of A Regents Professor Dante Lauretta says he is "amazed by the discoveries we've made" since the OSIRIS-REx spacecraft delivered an asteroid sample to Earth last year.

They all bring so much richness to the university with their accomplishments, their drive, and their aspirations," said Dr. Rebecca Gomez, Assoc. Dean in the College of Science.

Dr. Meixner recruited Dr. McIntosh to U of A in 2006 and mentored her in establishment of their joint hydrochemistry laboratory. They developed and co-taught Fundamentals of Water Quality, a core course for students in HAS and across campus and served on each other’s student committees.

Earth has been and can be warmer than it is today, but humans and animals can't adapt fast enough to keep up with climate change, a new study finds.

A new study provides a shortlist of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose.

The collaboration demonstrated the importance of broad inclusivity through an unusual geophysical field experiment that was conducted in Louisiana in 2022.

Sept. 22 marks the official first day of fall this year, but that's not always the case. The start of fall and spring is determined by an astronomical phenomenon called an equinox, when the sun is positioned exactly above Earth's equator. Jose Daniel Castro-Cisneros, a physics graduate student, explains how equinoxes work.
