Science Highlights
Looking a Hominid in the Mouth
Chimpanzee "oral microbiome" shows surprising frequency of species linked to human disease
Oral health may have a surprising impact on overall health. But scientists still don't fully understand which of the bacteria in our mouths cause disease. Researchers used data-intensive computation on the XSEDE-allocated Bridges supercomputer to identify the bacteria of the "oral microbiome." The project sequenced bacterial DNA from the tooth surfaces of chimpanzees and compared it to that of humans and Neanderthals. They discovered that relatively rare bacteria associated with disease in human mouths are common in our close evolutionary relatives.

Supercomputers Drive Ion Transport Research
XSEDE-allocated Stampede2 supercomputer powers path-sampling molecular simulation
Scientists are using the XSEDE-allocated Stampede2 supercomputer to help understand the rare event of salts in water passing through atomically-thin, nanoporous membranes. From a practical perspective, the rate of ion transport through a membrane needs to be minimized. To achieve this goal, however, it's necessary to obtain a statistically representative picture of individual transport events to understand the factors that control its rate. This research could help make progress in desalination for fresh water, in decontaminating the environment, and developing better pharmaceuticals.

Student Wins Undergraduate Poster Award at the ERN Conference in STEM
XSEDE-allocated supercomputers enable winning research
Tenecious Underwood, a senior at Livingstone College in North Carolina, has already had quite a year. Encouraged by a fraternity brother he met at the National Science Foundation's (NSF)  Emerging Researchers National Conference in STEM, Underwood found himself  applying for the Jetstream REU program. This program, hosted by Indiana University and supported in part by XSEDE, helped him launch a successful research project identifying frog calls with machine learning. Underwood recently presenting his findings via a poster at the ERN conference, and won first place in the Undergraduate Computer Sciences and Information Management category.

Program Announcements
Apply for Advanced Computing for Social Change (ACSC) program by April 1, 2020
Undergraduates from all majors/disciplines are encouraged to apply for Advanced Computing for Social Change (ACSC), an all-expenses paid opportunity to learn data analytics and computational thinking skills to address social change. This week-long data science challenge is co-located with the Practice and Experience in Advanced Research Computing Conference (PEARC20), held July 25-30, 2020 in Portland, Oregon. Apply by April 1, 2020!
IRIS and XSEDE Collaborate to Study Impact of Research Computing
A partnership between XSEDE and the Institute for Research on Innovation and Science (IRIS) has been initiated to study how access to advanced research computing resources and services available via XSEDE affect the collaboration networks and scientific productivity of participating researchers. A comparative analysis will be done of federally funded research teams that do and do not use XSEDE resources and services. This analysis will examine the effects of XSEDE allocations on the scale and composition of teams, structure of collaboration networks, profile of topics and funders, and research productivity and early impact. These findings will not only provide a new understanding of the impacts of XSEDE, it will inform evaluation and improvement of cyberinfrastructure programs nationwide.
Community Announcements
Call for Participation: Blue Waters Parallel Computational STEM Curriculum Capstone
Apply by March 20 for the Blue Waters Parallel Computational STEM Curriculum Capstone workshop June 8-12, 2020 at the National Center for Supercomputing Applications (NCSA). The Capstone aims to prepare faculty and professional staff to teach applied parallel modeling and simulation by incorporating (and updating) the materials and lessons learned from the successful Blue Waters Intern Petascale Institute that has been conducted multiple times over the last ten years.
NCAR Accepting Large-Scale Allocation Requests until March 23
NCAR is accepting large-scale allocation requests until March 23 from university-based researchers for the 5.34-petaflops Cheyenne supercomputer and the Casper data analysis and visualization cluster. Large-scale allocations at NCAR must be within the atmospheric and related sciences and supported by an NSF grant. Researchers are encouraged to review NCAR's  full eligibility criteria  and  NCAR's allocation instructions  before preparing their requests. In addition to requesting computing allocations, university projects can request long-term space on the NCAR Campaign Storage resource.
Apply by April 1 for the SC20 WINS Program
The WINS (Women in Networking) program is seeking qualified female U.S. candidates in their early to mid-career to join the SCinet volunteer workforce for SC20. Selected candidates will receive SC20 travel support and mentoring from well-known engineering experts in the research and education community. The deadline to apply is April 1, 2020.
Gateways 2020 Call for Participation
Gateways 2020 (October 19–21, Bethesda, Maryland) is now accepting submissions of short papers, demos, panels, tutorials, and workshops on the topic of gateways for science, engineering, or other disciplines. Gateways are user-friendly interfaces to scientific computing, data, and other domain-specific resources to support research and education.  Tutorials and Workshops submissions are due April 13. Short Papers, Demos, and Panels are due May 11, 2020. A poster deadline (open to all attendees) will be September 11.
Submit Proposals for GlobusWorld 2020 by March 9
