University of Arizona telescopes help capture dramatic changes in supermassive black hole's environment over the course of four years.

Using a cutting-edge optics system developed at the University of Arizona, researchers have gotten a glimpse of what our solar system likely looked like during its infancy.

A research team led by the U of A found that the brain of the extinct creature Jianfengia is very similar to that of living crustaceans, placing it in the ancestry of insects and crustaceans, not spiders and their relatives, as had been previously assumed.

Three newly discovered dwarf galaxies in an isolated region of space show evidence of star formation being cut short by events in the early universe.

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.

Researchers have developed a new biological sensing method that can detect substances at miniscule amounts, which is immediately useful for drug testing and other research.

Researchers from the U of A and Purdue University are developing VR-Bio-Talk, a tool that will let researchers work in virtual reality settings that mirror real agricultural environments.
