Before-and-after data from the few seconds it took the OSIRIS-REx spacecraft to collect a sample from asteroid Bennu revealed a surprise: The particles of Bennu's exterior are so loosely packed, they act more like a fluid than a solid.

As the Colorado River carved the Grand Canyon, it flushed away ancient groundwater. The discovery was made using a new method that determines the age of water based on how much of the radioactive element krypton-81 is present.

In many cases of epilepsy – which disrupts electrical activity in the brain and often results in seizures – the underlying cause is unknown. UArizona researchers may have found an explanation for some forms of epilepsy.

With a startup called CarbeniumTec, researchers in the College of Science and the College of Medicine – Tucson aim to bring to market new technology that reimagines how electricity is stored.

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.

Dr. Condon, an exemplary hydrologist at UArizona, was selected for the series for her outstanding research and mentoring efforts within the College of Science community.

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.

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.
