Restoring Chemotherapy Sensitivity by Boosting MicroRNA Levels

Atlanta, GA

Researchers have restored chemotherapy sensitivity in vitro to a line of human pancreatic cancer cells that had developed resistance.

MEMS microphones and piezoelectric strips pick up sounds of a bending and extending knee. Prof. Omer Inan is engineering a device to convert knee joint sounds into a signal he hopes medical researchers will be able to use. 

Hearing snap, crackle, pop may help heal your knee

Atlanta, GA

New acoustic device research reveals even a healthy knee makes cringeworthy sounds. But the audio can be turned into graphs, and researchers hope they will some day become medically useful.

Common Nanoparticle has Subtle Effects on Oxidative Stress Genes

Atlanta, GA

A nanoparticle commonly used in food and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside two types of cells.

Georgia Tech study finds people in food deserts, communities that have less access to grocery stores, eat food that is 5-17 percent higher in fats, sugars and cholesterol.

People in Food Deserts Eat Much Differently than the Rest of America

Atlanta, GA

A social media study uncovers what people eat, depending on their proximity to grocery stores.
