Analyzing tree-ring samples for spikes of naturally occurring radioactive carbon isotopes, a team led by U of A scientists has pinpointed the date of a massive solar particle eruption event that has long eluded researchers.

With funding from the Department of Energy, U of A researchers are working to revolutionize our understanding of how soil microbes influence climate change.

The Mentorship and Education in Science for Tucson program sends U of A juniors and seniors to local middle and high schools to provide one-on-one math tutoring to students.

With a $3.9 million grant from the National Institutes of Health, precision nutrition researchers will conduct a clinical trial to explore how ancestry and genetics affect the body's response to omega-3 fatty acids.

Researchers from the U of A and ASU this week showcased new techniques to improve urban water use practices. Their work was supported by the Smart Tree Watering Regents' Research Grant.

U of A researchers have created the first astronomical equivalent of a fingerprint database for satellites, a critical first step toward easily identifying human-made objects in the increasingly crowded geostationary orbit.

Animals use vibrant colors to attract mates or warn predators. A recent study finds that there has been a dramatic explosion of color signals in the last 100 million years.

Researcher Judith Su will use the funding to build a handheld version of her FLOWER device that can detect trace chemicals and enhance safety for military personnel.

Widespread planting of transgenic crops has led to rapid adaptation by some pests, including the corn earworm. Researchers are studying a genetic factor that may play a role.

Astronomers used the Hubble and James Webb Space Telescopes to take an in-depth look at the debris disk surrounding Vega, a nearby star. Surprisingly, they found no obvious evidence of large planets plowing through the disk, as is common around other young stars.
