Embracing the unexpected can create opportunities that lead to new explorations, new knowledge and new discoveries. That idea is at the center of the 19th annual College of Science Lecture Series, which will take on the theme of "Surprise Twists That Transformed Science."

In the same lab where university scientists invented ways to study climate history in tree rings, associate professor Bryan Black is using a similar technique – but with tiny fish bones.

NASA scientists last week removed the two stuck fasteners on the sample container that had prevented researchers from accessing much of OSIRIS-REx's asteroid Bennu sample.

With a new installation on Tumamoc Hill, a University of Arizona experimental philosopher wants to encourage people to imagine 1,000 years into the future – and plan accordingly.

Under the leadership of the University of Arizona's Dani Mendoza DellaGiustina, the former OSIRIS-REx spacecraft sets off on a journey to study asteroid Apophis and take advantage of the asteroid's 2029 flyby of Earth.

For 20 years, MEAD has welcomed, engaged, and appreciated thousands of educators, both in-state and beyond. An impressive list of sponsors ensures that all Arizona teachers can experience research-based, high quality professional development at no cost.

A new partnership among the Arizona Commission for the Deaf and the Hard of Hearing and the three state universities provides free hearing health care for eligible people age 21 or older who do not have insurance.

With its stout orange trunk and long, graceful needles, the tree looks like any other ponderosa pine growing on Mount Bigelow. But a sliver of its wood, taken amid Earth’s warmest year on record, shows that this tree has a story to tell — and a warning to offer.

At the university's Kuiper-Arizona Laboratory for Astromaterials Analysis, a suite of instruments allows researchers to study the particles collected by the OSIRIS-REx mission the down to the atomic scale.

The research will help determine the underlying causes of disruption at the biochemical, cellular, and functional levels, which will ultimately inform how synapses grow as animals develop and how this may go awry in neurodevelopmental diseases.
