Travis Goodloe ’15 was recently awarded a Sigma Xi Grant-in-Aid of Research for his summer research project that he will be conducting in collaboration with Elliott Asisstant Professor of Biology Dr. Kristian M. Hargadon ’01. Travis will be developing an assay to measure melanoma cell metastasis to tumor-draining lymph nodes, and he will use this assay to investigate the rate of lymph node metastasis by melanomas of differing tumorigenicity. Lymph node metastasis is often associated with immune suppression in melanoma patients, and the assay developed by Travis will therefore be a useful system for investigating factors that regulate the spread of melanomas to regional lymph nodes and for assessing the quality of anti-tumor immune responses in tumor-free versus tumor-involved lymph nodes.
The Sigma Xi Grants-in-Aid of Research (GIAR) program has provided undergraduate and graduate students with valuable educational experiences since 1922. By encouraging close working relationships between students and mentors, the program promotes scientific excellence and achievement through hands-on learning.
Three Hampden-Sydney seniors, Jay Brandt, Chris Ferrante, and Stephen Woodall, recently presented their research work at the annual Experimental Biology (EB) meeting in Boston. EB is a federation of six different biological professional societies and is one of the largest scientific conferences in the world.

It was a big meeting!
On March 24, five Hampden-Sydney College and four Longwood University students were inducted into Sigma Xi, the international honorary scientific research society. Founded in 1886 to honor excellence in scientific investigation and to encourage collaboration among researchers in all fields of science and engineering, the Society now consists of over 500 chapters at academic, industrial, and government research institutions and has nearly 60,000 members in more than 100 countries around the world. The Longwood University/Hampden-Sydney College chapter of Sigma Xi was reactivated in 2013, and the two institutions now alternate hosting an annual Sigma Xi Research Symposium that features a keynote speaker and student poster presentations highlighting recent research activities on both campuses.

Six Hampden-Sydney College students were recently selected to participate in the newly established H-SC/Centra Pre-Health Rotational Shadowing Program. Benjamin Lam, Brant Boucher, DJ Bines, Jake Farrar, James Lau, and Robert Kerby will begin their rotations this semester and will have the option to continue their shadowing in the Fall 2015 semester as well. Through this program, these students will be exposed to various fields of medicine as they rotate through departments that include: Family Medicine, General Surgery, Cardiovascular Medicine, Emergency Medicine, the ICU, Gastrointestinal Medicine, OB/Gyn, Radiology, and Pharmacy. The shadowing experience afforded by this partnership will provide these students with valuable healthcare exposure hours that will increase awareness of potential career paths in healthcare and enhance preparation for graduate and professional programs in medicine and the health sciences. Together, these benefits will provide H-SC students with a competitive edge as applicants to medical and health professional schools.
The H-SC/Centra Pre-Health Rotational Shadowing Program will be ongoing, and applications will be solicited in the Fall 2015 semester for a new set of rotations to begin the following spring.

The Genomics Education Partnership (GEP), a coalition of undergraduate institutions started by Dr. Sally Elgin of Washington University in St. Louis for the purpose of bringing original and authentic research opportunities to all undergraduate students, has announced the acceptance of its latest peer-reviewed publication based on student work. The paper is found in the journal G3: Genes,Genomes, Genetics and has among its authors Greg Robertson ’12, former Hampden-Sydney student Samuel Smith, and Assistant Professor of Biology Mike Wolyniak. The paper, entitled “Drosophila
Muller F elements maintain a distinct set of genomic properties over 40 million years of evolution”, examines how study of the fruit fly genomes can reveal a great deal about how different species develop and evolve over time. Robertson, Smith, and Wolyniak examined individual sections of
genomic sequence from a bioinformatics perspective, annotating the sequence for coding sequence start and stop sites and well as splice sites.
The GEP is one of several initiatives available to Hampden-Sydney biology students as they learn how to conduct real science during their time in Gilmer Hall.

Throughout the Fall 2014 semester, the H-SC Molecular and Cellular Biology class worked to discover and characterize new phages that infect bacteria of the genus Bacillus
as part of their original research in conjunction with the Howard Hughes Medical Institute (HHMI) SEA-PHAGES project. As part of this project, representatives of the class travelled to the University of Mary Washington, a SEA-PHAGES collaborator, to get pictures of their phages on their electron microscope. The pictures provided the students invaluable insight on the nature of their new discoveries, which have been catalogued with the central SEA-PHAGES lab at the University of Pittsburgh as part of their ongoing work on viral evolution.

“HSCtrl”, as discovered by Chris Ferrante ’15. Note the DNA spilling out from the capsid head of this sample.
Phage “Archie14″, as discovered by Stephen Woodall ’15, has been sequenced by the University of Pittsburgh and returned to H-SC for analysis. The next step in the research will be done by students interested in bioinformatics who will thoroughly examine Archie14′s genome for particular genetic features that make it unique from other phages. This project, along with projects in several other H-SC biology classes, is part of an effort in the department to make research a central part of the H-SC biology experience.
Three Hampden-Sydney biologists, Jay Brandt ’15, Chris Ferrante ’15, and Taylor Meinhardt ’16, accompanied Professor Mike Wolyniak to the Annual Meeting of the American Society for Cell Biology (ASCB) in Philadelphia. The ASCB Annual Meeting attracts roughly 8,000 scientists and exhibitors from around the world each December, including Nobel laureates and other top names in the field. Jay and Chris presented their joint project on peptide synthesis as a potential novel form of antibiotic. The research is both their Senior Fellowship project at H-SC and a semester-long classroom research opportunity in which Jay and Chris will work with Professor Wolyniak’s Genetics and Cell Biology class in the spring 2015 semester to collect and analyze data. First, Jay and Chris presented at the undergraduate poster session, featuring 150 different projects drawn across the full gamut of cell biology fields.

The Fall 2014 Molecular and Cellular Biology class at Hampden-Sydney has been an active participant in the Howard Hughes Medical Institute SEA-PHAGES program, isolating and characterizing viruses that infect Bacillus
bacteria as part of a nationwide project on viral evolution and genomics. As part of this class experience, 5 students from the class prepared research presentations for the James Madison University “Phage Phaire”, a gathering of research students from James Madison, Virginia Commonwealth University, Old Dominion University, the University of Mary Washington, and Hampden-Sydney. These 5 schools are part of the current 74-member nationwide HHMI SEA-PHAGES alliance and organize two research meetings per year to provide students with the chance to share their work with their peers.

On November 13, the Longwood University/Hampden-Sydney College Chapter of Sigma Xi hosted the 2nd annual Sigma Xi Research Symposium. Sigma Xi is an honorary research society that promotes excellence in scientific investigation in all fields of the life and physical sciences. The Symposium was held at Longwood University’s Chichester Science Center and featured a keynote speaker and poster presentations by undergraduate students from both institutions. Dr. Pieter deHart, Assistant Professor of Biology at the Virginia Military Institute, delivered the Symposium’s keynote address entitled ““Feeding the Beast: Explorations into the Feeding Ecology of Apex Predators.” This engaging talk focused on work that Dr. deHart has conducted with several undergraduate students at VMI and included ecological studies on the feeding habits of a wide variety of predators, ranging from praying mantids to coyotes. Following his keynote address, Dr. deHart interacted with several students during the Symposium’s poster session, which featured research conducted by undergraduates at both Hampden-Sydney College and Longwood University. 12 H-SC students and 13 Longwood University students from the Departments of Biology and Chemistry presented their work, and this session provided an excellent opportunity for close interaction and sharing of ideas between students and faculty from both institutions. To follow up on the success of the Symposium, Hampden-Sydney College will host an initiation ceremony in Spring 2015 for the induction of new student and faculty members to the Society.
