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.

U of A scientists will participate in many aspects of NASA's Europa Clipper mission, which will orbit Jupiter and make 49 flybys of its moon Europa to study the moon's icy shell and help researchers better understand what lies beneath.

The Center for Human Space Exploration prepares humans to thrive in the harsh environments of space. Founding director Trent Tresch discusses the center's projects and how they support NASA's goals.

For the first time, one of the Giant Magellan Telescope's primary mirror segments, produced at the U of A Richard F. Caris Mirror Lab, has been integrated into a support structure that will maintain the mirror's shape once mounted on the telescope.

Every second, more than 3,000 stars are born in the visible universe. Many are surrounded by protoplanetary disks – swirling "pancakes" of hot gas and dust, from which planets form. U of A researchers have obtain detailed insights into the forces that shape protoplanetary disks.

The Arizona Astrobiology Center received a $1 million gift from Eugene Jhong, a retired Google software developer, to support research on the origins of life and consciousness.

U of A Regents Professor Dante Lauretta says he is "amazed by the discoveries we've made" since the OSIRIS-REx spacecraft delivered an asteroid sample to Earth last year.
