For decades, UA scientists have contributed to the research that has shaped our understanding of our solar system and the universe – beginning with the Apollo 11 mission 50 years ago.

A bad night's sleep may result in a spike in blood pressure, offering a possible explanation for why sleep problems have been shown to increase the risk of heart attack, stroke and even death from cardiovascular disease.

In the most detailed analysis of how sands move around on Mars, a team of planetary scientists led by the UA found that processes not involved in controlling sand movement on Earth play major roles on Mars.

Researchers might have found a way to detect neurodegeneration before brain cells are lost for good. Earlier detection could provide therapeutic drug treatments a chance to work.

Air pollution from industrialization is the likely culprit behind the reduced precipitation from the Asian monsoon, a phenomenon that affects almost half of the world’s population.

A "deep learning" approach to detecting storms on Saturn show the vast regions affected by storms and that dark storm clouds contain material swept up from the lower atmosphere by strong vertical winds.

Armadillos as big as Volkswagens and other grass-eating mammals became more diverse in South America about 6 million years ago because of shifts in atmospheric circulation.

While searching for the origins of Titan’s methane and the organics that coat its surface, UA researchers made the unexpected discovery of a large ice feature on Saturn's largest moon.

A UA team shows that evolution is driven by dependency on other species within ecological communities – testing a long-held idea of the late UA professor George Gaylord Simpson.

A UA geosciences undergraduate developed an innovative method of using ancient urine salts to reveal when humans in ancient Turkey began shifting from hunting to herding.
