Autocoding Cancer

An algorithm developed by the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) in partnership with the National Cancer Institute (NCI) is speeding up classification, or coding, of cancer pathology reports. The early results from the Cancer Moonshot program show that the algorithm dramatically reduces the time it…

Data Transfer Tool Makes New Connections at ORNL

Data is the fuel that propels scientific research, and fortunately for scientists, there is no shortage of data in the modern world—a single scientific instrument can produce terabytes of data. However, just as important as collecting the data is being able to access it and analyze it. For researchers at…
