Combining advanced climate model simulations with marine sediment analyses, a new study reveals what may have triggered massive ice sheets to form in Scandinavia, ringing in the last glacial period some 100,000 years ago.

In addition to observing Juneteenth as a paid holiday for the first time in 2023, the university is developing a yearlong campaign to tell the story of Juneteenth and Black people in the Southwest.

Desert dwellers know it well: the smell of rain and the feeling of joy that comes with it. The familiar fragrance, which is the result of oils and chemicals released by desert plants, may offer stress-reducing health benefits, University of Arizona research suggests.

Title IX, the landmark legislation designed to eliminate sex discrimination in education, marks its 50th anniversary this year. Tammi Walker, an associate professor of law, talks about the legislation's impact and evolution.

The Contereas Fire has reached Kitt Peak National Observatory, where several University of Arizona-managed astronomy facilities are located.

Evidence suggests that carbon nanotubes, tiny tubes consisting of pure carbon, could be forged in the envelopes of dust and gas surrounding dying stars. The findings propose a simple, yet elegant mechanism for the formation and survival of complex carbon molecules in space.

Weather watchers are invited to submit their monsoon predictions online in the Southwest Monsoon Fantasy Forecasts game. Created by UArizona climate researchers, the game draws inspiration from fantasy sports.

Astronomers have discovered a new type of stellar system that contains only young, blue stars. The structures are thought to be created when galaxies collide with hot gas in something of a galactic belly flop.

As heat waves blaze across the U.S., UArizona researcher Ladd Keith says city planners should take the lead in managing and mitigating extreme heat. Keith recently co-authored a report, published by the American Planning Association, that gives planners a set of principles and guidelines to address extreme heat in their communities.

Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. Astronomers have created a detailed, three-dimensional image of one dying hypergiant, providing new insights into what happens at the end of these rare stars' lives.
