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

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

Refining tools for Big Data

You may have been hearing about the advent of Big Data: truckloads of information coming from cell phones, satellites, microscopes, and perhaps someday, wearable health monitoring devices.

At Emory, specialists in biomedical informatics have been in the forefront of efforts to design software that will allow scientists to learn from these mountains of data. Fusheng Wang was recently named as co-PI on a five-year $5 million National Science Foundation grant to create MIDAS (Middleware for Data-Intensive Analytics and Science), part of the NSF’s Data Infrastructure Building Blocks program. For this grant, the team consists of seven institutions: Indiana University (lead — Geoffrey Fox), Arizona State, Emory, Kansas, Rutgers, Utah and Virginia Tech.

Wang also recently received a NSF Career award in this same area.

The MIDAS project addresses major data challenges in seven different communities: biomolecular simulations, network and computational social science, epidemiology, computer vision, spatial geographical information systems, remote sensing for polar science, and pathology informatics. Wang is responsible for pathology informatics and geospatial, gathering requirements from those communities and implementing the spatial query and parts of the image analysis library. The libraries are supposed to be interoperable across a range of computing systems including clouds, clusters and supercomputers. The project includes a plan to develop a open online course (MOOC), according to the NSF.

Stem cell research center gets NSF support

Stem cell research is on the verge of impacting many elements of medicine, but scientists haven’t yet worked out the processes needed to manufacture sufficient quantities of stem cells for diagnostic and therapeutic purposes.

Todd McDevitt and Robert Nerem

The National Science Foundation (NSF) has awarded $3 million to Georgia Tech to fund a center that will develop engineering methods for stem cell production. The program’s co-leaders are Todd McDevitt, PhD, an associate professor in the Georgia Tech/Emory Department of Biomedical Engineering and Robert Nerem, director of the Emory/Georgia Tech Center for Regenerative Medicine (GTEC), which will administer the award.

“Successfully integrating knowledge of stem cell biology with bioprocess engineering and process development is the challenging goal of this program,” says McDevitt.
