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.
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.
A concept developed by UArizona aerospace experts and a NASA planetary scientist takes inspiration from albatross flight to learn more about the Red Planet's atmosphere and geology.
The better someone knows a topic, the more difficult their writing about that subject can be to understand. UArizona researchers have developed the Writing Clarity Calculator to help scholars determine how clear their writing is.
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.
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.
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.
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.
Snapping an image of a black hole is just the beginning, says researcher Chi-Kwan "CK" Chan. To really understand the image, it must be compared with black hole simulations. UArizona worked with partners to create the world's largest simulation library.
UArizona astrophysicists Feryal Özel and Dimitrios Psaltis identified Sagittarius A* as an ideal target black hole more than 20 years ago. They call it a "Goldilocks black hole," with an environment "just right" for capturing an image.
