Mapping a large coastal glacier in Alaska revealed that its bulk sits below sea level and is undercut by channels, making it vulnerable to accelerated melting in an already deteriorating coastal habitat.

When engineers 3D-print metal objects, they use metals originally developed for conventional manufacturing. It works, but not as well as it could. Two UArizona experts are using a new suite of equipment to develop alloys optimized for both 3D printing and hypersonic flight.

The university's Center for Innovation – a business incubator network that empowers science and technology startups to bring their ideas to market – had an economic output of $35.3 million in 2021, according to a new analysis.

Dozens of presentations from University of Arizona experts, a film festival and more are on tap at this year's Wonder House as the university returns to South by Southwest.

CatSat is a small satellite carrying a new communications concept – an inflatable antenna – into space. Led by UArizona students and supported by engineers from local aerospace companies, the project offers students a rare chance to get hands-on experience with spaceflight technology.

Future space missions likely will send robots to scout out underground habitats for astronauts. UArizona engineers have developed a system that would allow autonomous vehicles to explore caves, lava tubes and even oceans on other worlds.

More environmentally friendly agriculture practices are needed to keep the farming industry strong in Arizona, a report from the university's Southwest Center finds.

Male red-bellied lemurs see a fourfold increase in estradiol during the third trimester of their mates' pregnancies. Researchers suspect that the hormonal shift is part of nature's way of preparing the lemurs for fatherhood.

Climate models and geologic archives are at odds over whether Earth gradually warmed or cooled over the past few thousand years. Researchers tackle this global "temperature conundrum" in a new paper.

With NASA's James Webb Space Telescope, researchers are observing star formation in nearby galaxies with unprecedented resolution at infrared wavelengths.
