Rephrase "In this current work we expand..." to "This current work expands on last month's Leadership Computing article.."
Maybe change the ordering of the second and third paragraph because the reference to the NSF resources comes out of the blue. So perhaps
"This article highlights several Consortium projects and extends the discussion in the previous issue by shifting focus to projects hosted outside the Department of Energy’s Leadership Computing Facilities. For example, the National Science Foundation is a major partner in this effort, with many of its funded advanced computing organizations making significant contributions. These include XSEDE, which is managing request processing and allocations for consortium resources, the University of Texas at Austin’s Texas Advanced Computing Center (TACC), the Pittsburgh Supercomputing Center (PSC), the San Diego Supercomputing Center (SDSC), and many others. We also broaden the discussion beyond the Consortium by bringing in additional supercomputing-enabled COVID- 19 research to showcase the range of contributions that the national cyberinfrastructure is making to global efforts to stop the pandemic. This article touches on research efforts to learn how SARS-CoV-2 spreads among different populations, the biology and structure of the virus and its mechanisms of infection, and to develop effective vaccines for prevention and antiviral therapies for treatment."
