U of A-led research shows evidence of social microbial transmission in a solitary species, which could help us better understand how microbes are exchanged in humans.

New observations that U of A astronomers helped make with the James Webb Space Telescope solidify previous hints of a giant planet orbiting the sun's closest neighbor.

All animals–including humans–are home to trillions of microbes that are crucial to health. Many of these microbes spread socially, relying on close contact or cohabitation. But what happens when those social routes don’t exist?

Research shows small, frequent fires by mobile hunter-gatherer groups controlled landscape-scale fire activity.

A study led by the University of Arizona finds that immersive, multi-semester undergraduate research experiences can significantly enhance student confidence, scientific identity, and career readiness—especially for those pursuing degrees in neuroscience and the biological sciences.

In a new study, researchers have captured the first-ever nanoscale, low-temperature optical images of exciton spectra, opening new doors to the future of quantum material applications.

Finely preserved brain features in a tiny marine arthropod fossil suggest that arachnids – spiders and their close kin – may have first evolved in the ocean rather than on land, challenging conventional wisdom.

The project enhances LBT’s visible-light capabilities, advancing U.S. leadership in next-gen astronomy.

The meteor impact that created one of Arizona's most recognizable landmarks and the wood and sediments found in a cave in the Grand Canyon are strikingly similar in age. A new study involving a U of A dendrochronologist suggests they could be related.

Discovered only a week ago, comet 3I/ATLAS is only the third known visitor from outside the solar system. U of A astronomer Carson Fuls explains what makes the comet special – and why we can only guess where it came from.
