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?

Led by graduate students Aaron Byrd and Lucas Marmorale, the work identifies two molecular players as key drivers of TDP-43 clearance. The abnormal buildup of this protein in the wrong part of neurons is a defining feature of ALS.

From AP high school science classes to researching in a lab, one student has used his natural curiosity to reach new levels of success and opportunities.

Natalie Rawlings, a senior pursuing dual degrees in Molecular and Cellular Biology and Biochemistry in the Franke Honors College, exemplifies undergraduate research excellence in MCB.

Not much is known about how organisms colonize brand-new habitats for the first time. A new study led by a team of ecologists and planetary scientists from the University of Arizona provides glimpses into a poorly understood process.

The College of Science recognized outstanding seniors for their contributions in and out of the classroom. Jasmine Meredith is this semester's recipient from Molecular & Cellular Biology.

A study from researchers in the MCB department 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]

A W.A. Franke Honors College student, Natalie Rawlings, has been named a 2025-26 Astronaut Scholar by the Astronaut Scholarship Foundation.

The Schroeder lab recently discovered that nuclear EGFR (nEGFR) prevents detection of breast cancer by Natural Killer (NK) cells. NK cells can seek out and destroy any cancer cells they can recognize, and the ability of nEGFR is a mechanism used by breast cancer to evade this arm of the immune system.
