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.

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 "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.

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.

Astrophotographer Adam Block talks about the galaxy known as Messier 87, home of the supermassive black hole photographed by the Event Horizon Telescope.

Lia Medeiros, and 20 other UA students, expanded their educations by participating in efforts to see the unseen with the Event Horizon Telescope.

With the help of two radio telescopes coordinated by the UA, astronomers in the Event Horizon Telescope collaboration have taken the first direct image of a black hole, a prediction of Einstein's General Theory of Relativity.
