Rie Siddaiah's graduate research is being conducted in the Charest lab, where she studies the impact of the small GTPase Ras and its relationship with key molecular players in the progression of metastasis. [external link]

A protein complex inside every living cell that tells it how to grow. Problems with the protein's signaling system can lead to neurological issues. University of Arizona biologist Andrew Capaldi describes how scientists are examining the inner workings of cells.

Two scientists combine complementary strengths in RNA biology and aging neuron research to advance new approaches in studying ALS: Ross Buchan and Kevin Rhine are using a new effort at the University of Arizona BIO5 Institute to bring faculty and clinicians together across disciplines to better understand, and ultimately treat, ALS.

Dr. George Sutphin, associate professor in the Department of Molecular and Cellular Biology, opened the Science Lectures series 2026 on February 4 with the topic of aging and the question: how long can we stay healthy?

A new study from researchers in the Department of Molecular and Cellular Biology reveals that TORC1, a protein complex long known to regulate cell growth, functions as a sophisticated central computer rather than a simple on/off switch.

Every great scientific discovery has a story behind it. For doctoral candidate Cristina Padilla, that story began not in a state-of-the-art lab, but in the small town of Yuma, Arizona. Her path to a research career was anything but direct. [external link]

Among the College of Science's 2025 Galileo Circle Awards recipients are George Sutphin and Emily Dykstra.
