Overcoming cardiac pacemaker "source-sink mismatch"

Instead of complication-prone electronic cardiac pacemakers, biomedical engineers at Georgia Tech and Emory envision the creation of “biological Read more

Hope Clinic part of push to optimize HIV vaccine components

Ten years ago, the results of the RV144 trial– conducted in Thailand with the help of the US Army -- re-energized the HIV vaccine field, which had been down in the Read more

Invasive cancer cells marked by distinctive mutations

What does it take to be a leader – of cancer cells? Adam Marcus and colleagues at Winship Cancer Institute are back, with an analysis of mutations that drive metastatic behavior among groups of lung cancer cells. The findings were published this week on the cover of Journal of Cell Science, and suggest pharmacological strategies to intervene against or prevent metastasis. Marcus and former graduate student Jessica Konen previously developed a technique for selectively labeling “leader” 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.
