Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Best Image Contest

Focal adhesions in Technicolor

i-QMq63rH-S

Mouse embryonic fibroblasts forming focal adhesions

Congratulations to Alejandra Valdivia, PhD, winner of the Best Image contest held as part of the Emory Postdoctoral Research Symposium, which takes place next week (Thursday, May 19). She is in Alejandra San Martin’s lab, studying NADPH oxidase enzymes and how they regulate cell migration.

Valdivia submitted this image of mouse embryonic fibroblasts forming focal adhesions, points of contact of the cell with the extracellular matrix. Focal adhesions allow the cells to adhere and migrate.

Explanation: Red is for paxillin, a protein concentrated in focal adhesions. Green is phalloidin, a toxin from mushrooms that binds one type of the cytoskeletal protein actin, seen here as stress fibers. Blue is DNA, showing the cells’ nuclei.
