Seniors struggle with memory because of clutter, study finds

Image shows adult human fibroblast cells with intracellular proteins involved in adhesion of these cells to an extracellular matrix. Magenta represents actin stress fibers in a cell and green staining represents a focal adhesion protein vinculin, which together contribute to how strongly these cells adhere to a matrix surface. Blue is the nucleus of a cell. These fibroblasts are converted to human induced pluripotent stem cells through a reprogramming process during which restructuring of the adhesion prote

Roadmap for Advanced Cell Manufacturing Shows Path to Cell-Based Therapeutics

Atlanta, GA

An industry-driven consortium has developed a national roadmap designed to chart the path to large-scale manufacturing of cell-based therapeutics.

A tailor-made ratiometric sensor makes a baker's yeast cell light up green, as Georgia Tech scientists use it to track the movements of the essential toxin heme.

Heme, a Poisonous Nutrient, Tracked by ‘Green Lantern’ Sensor

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.

Using optogenetics and other technology, researchers have for the first time precisely manipulated bursting activity of cells in the thalamus, tying it to the sense of touch.
