Science Highlights
Hijacking of Pro-Vaccination Twitter Effort Is Focus of Analysis Using XSEDE Resources
Tweets reveal how anti-vaxxers dominated event by health professionals
A well-intentioned 2020 Twitter effort by doctors to support vaccination called "#DoctorsSpeakUp" backfired in a flurry of anti-vaccination tweets. Using XSEDE-allocated supercomputers and working with XSEDE's Extended Collaborative Support Services (ECSS), scientists analyzed Twitter content on the day of that event, discovering the elements that made the anti-vaccination message so strong, as well as the superior pre-event organization that made it overwhelming. Based on these findings, the team created a list of seven best practices for future social media events in support of medical and public health efforts.

XSEDE-Supported Modeling Results in New Findings for Preeclampsia Patients
Study shows preeclampsia associated with low-oxygen microenvironment in uterus
According to the Centers for Disease Control and Prevention (CDC), preeclampsia, or pregnancy-related hypertension, occurs in roughly one in 25 pregnancies in the United States. The causes are unknown and childbirth is the only remedy, which can sometimes lead to adverse perinatal outcomes, such as preterm delivery. To better understand this serious pregnancy complication, which reduces blood supply to the fetus, researchers used XSEDE allocations to conduct cellular modeling to detail the differences between normal and preeclampsia placental tissue. Their study showed that preeclampsia is associated with a low-oxygen microenvironment in the uterus, and provide insight for future diagnostic tool development and medication identification.

Cloud Computing Expands Brain Sciences
Leading neuroscientist relies on XSEDE resources for platform
New cloud technologies are becoming necessary to help researchers collaborate, process, visualize, and manage large amounts of data at unprecedented scales. These include supercomputers, many of which are allocated by XSEDE, including Jetstream, Stampede2, and Bridges-2. One such cloud project is, an NSF-funded computing platform that provides a full suite of web services to support reproducible research on the cloud. More than 1,600 scientists from around the world have accessed the platform thus far. allows them to upload, manage, track, analyze, share, and visualize the results of their data.

Supercomputers Aid in Maternal and Paternal DNA Research
XSEDE allocations may help improve medicine and food production
Thanks to XSEDE-allocated supercomputers, researchers now better understand contributions from maternal and paternal lineages in genome sequences. The supercomputers were used to showcase the performance of a novel computer science optimization method on genome data from a thorny skate, a mosquito, and a Chardonnay grape. The optimization method, known as HapSolo, helps researchers better understand an array of genetic relationships. This new knowledge may lead to improved medicine and food production for an array of populations.

Program Announcements
Six New HPC Badges Available through XSEDE
XSEDE Badges are a type of digital micro-certifications which allow people in the HPC community to expand their skill sets and quickly demonstrate competency in a particular area. Over the past year, XSEDE has added six new badges focused on areas ranging from Python to Matlab. XSEDE badges are issued from the XSEDE HPC Training Portal, which can be accessed at
XRAS Named ORCID Certified Service Provider
XSEDE developed the XSEDE Resource Allocations System (XRAS) as a software-as-a-service tool to manage allocations processes with the goal of allowing other organizations to leverage XSEDE's investment for the national research computing infrastructure. Since being deployed for XSEDE in 2014, XRAS has been adopted by half a dozen organizations, including the COVID-19 HPC Consortium. Now, XRAS has been named an official ORCID Service Provider! ORCID members can configure XRAS to allow researchers to link to their ORCID iDs, and awarded allocations are posted to researchers' ORCID profiles as an ORCID Research Resources entry.
Encourage Undergraduates to Apply for C4C!
Do you know an undergraduate who wants to learn data science skills to create a positive change in their community? All undergraduate students are invited to apply for the Computing4Change (C4C) Competition, a social action-themed experience during SC21! All majors are welcome. No prior coding experience required. The program will take place during SC21, November 12-19, 2021. The deadline to apply for C4C is August 2, 2021.
Community Announcements
PEARC Seeking Nominations for 2023 Conference Chair and Steering Committee Members
The PEARC Conference seeks nominations for individuals to serve as the PEARC 2023 Conference General Chair or as PEARC Steering Committee Members-at-Large. All members of the community are eligible to serve in these roles. Nominations will be accepted until July 2, 2021, at 11:59pm Central Time. Nominations can be sent to
NSF Awards New Research Computing and Data Resource and Career Center
NSF has recently funded a pilot CoE to build upon the work of several CaRCC working groups and advance support for research computing and data professionals. With a focus on advocacy, training, and workforce development, a team from Harvard, Internet2, UC San Diego, and the University of Utah have been awarded a nearly $1.5 million, two-year grant from the National Science Foundation (NSF) to address these challenges.
TrustedCI Announcing Call for Proposals at the 2021 NSF Cybersecurity Summit
The 2021 NSF Cybersecurity Summit is scheduled to take place virtually the week of October 11, 2021. The summit intends to further the NSF community's understanding of cybersecurity strategies that strengthen trustworthy science: what data, processes, and systems are crucial to the scientific mission, what risks they face, and how to protect them. Those interested in submitting proposals for summit presentations and workshops are invited to do so by July 2.
