Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Emory team wanted to develop a standard low-volume approach that would avoid multiple processing steps, which can lead to loss of material, variable recovery, and the potential for Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, 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.
