2014 Was a Very Good Year!

nicole graduationAs we close out 2014, I thought it would be an appropriate time to look at the events from late in the year that demonstrate some of the accomplishments of the BIMS program.

1. Nicole McGunegle (middle left, with our Dean Alicia Wyatt and human biology professor Dr. Larry Sharp) became the sixth BIMS majors to complete Honors thesis research this year.  Her work was on heat resistance of wild type and genetically-modified spore-forming bacteria.  She was one of four Biology Department graduates in December, the others being Kelly Croci, Shayna Hoag, and Collin Valdez.  All four are pursuing advanced graduate or professional school programs (Medical School, Physician Assistant school, Optometry School, Nutrition and Dietetics graduate program).

2.  There was an official announcement that the Department of Biology was the recipient of a 160-acre tract of land in Callahan County that will serve as a field research station.  The donor is Bill Libby, long-time professor of history and religion and the founder of the Cross-Country program at McMurry.  The field station will be called Firebase Libby, in recognition of Bill’s time spent as a chaplain with the 101st Airborne in Viet Nam.  Every facet of McMurry’s biology and biomedical science programs has identified ways in which this valuable asset can be used for research and student projects.  More here:  http://blogs.mcm.edu/sncs/?p=1159.

3. On the research front, Dr. Tom Benoit received notification in December of the acceptance of an article written for the Journal of Microbiology and Biology Education.  It details the use of diatomaceous earth in construction of Winogradsky columns for study of microbial ecology and mineral cycling in biological systems.  Three professors also received good news about funding for research during the Christmas break:  Dr. Anna Saghatelyan is partnering with Dr. Hyun-shun Shin of Chemistry on a project to identify new antimicrobials from area plants.  They will receive funding from the Sam Taylor Foundation.  This work includes the Honors Research of Kara Black, which was presented at the regional ACS conference this fall.  More here:  http://blogs.mcm.edu/sncs/?p=1150.  And Drs. Dana Lee and T.J. Boyle both were notified of their receipt of KIVA grants for next year, funding for research on the genomics of bats and the distribution of crabs in lakes of west Texas.

4. And most exciting has been the resurgence of the Biology Club and Tri-Beta, under the capable leadership of Drs. Boyle and Lee.  First came a very successful “Pie a Professor” fundraiser (http://blogs.mcm.edu/sncs/?p=1145) that provided the funding to begin an effort to greatly expand the recycling efforts on campus (http://blogs.mcm.edu/sncs/?p=1155).  This is only the beginning of growth and contribution to the campus and community from the Biology and Biomedical Science students at McMurry.

5.  Finally, as the year ends we find a new beginning on the horizon for the Department of Biology.  Extensive revisions to the BS Biology, BS Biomedical Science, and BS Life Sciences degrees are coming!  New courses and a roadmap for the program changes are in the final stages of approval, and incoming students for the Fall 2015 semester will benefit from the tweaks being made.  A common biology core of 16 hours, including a junior seminar course to explore careers and prepare for entrance exam tests for graduate and professional programs, will be taken by all students.  We expect great things to come from these data-driven improvements!

So, from all of us at McMurry, we hope 2014 was equally productive and gratifying.  And we hope all of us will experience an even better 2015!

Dr. Benoit’s “Joy of Pet Ownership”

by gwilson on Oct.18, 2013, under Projects

2013-10-18_15-43-07_756 Each year when Dr. Benoit teaches our freshman BIMS course on Unicellular Organisms, students leave with more than just knowledge and a grade….they take with them a pet.

In BIMS 1101 Unicellular Organisms Lab, Dr. Benoit takes students through an amazing tour of the unseen world, one filled with bacteria and protozoa and algae and yeast.  The course teaches basic cell biology and the diversity that exists among the smallest forms of life.  As a way of demonstrating the metabolic diversity of bacteria, all students create Winogradsky columns by filling Falcon flasks with diatomaceous earth, a variety of chemicals, and some water drawn from pond sludge (see photo).  These are the students’ pets, cared for and tended to by the students.  Dr. B encourages students to drop by the lab regularly to visit their pets and to enjoy their journey to maturation.  At the end of the semester, students are free to take them home where they can continue to mature and change for many years.

The preparation begins white usually, but chemical changes caused by a variety of bacterial turn the many minerals present into a technicolor show.  A good balance of chemicals and diversity of bacteria can result in reds and greens and blacks and yellows and purples as one species of bacteria after another transforms the minerals into colorful compounds.  It is the microbial equivalent of a garden filled with diverse plants.

As educational as the Winogradsky column is, the fun take on the project by Dr. Benoit demonstrates an important component of science at McMurry – if it isn’t fun, something is wrong!

BIMS 1101 A Hit With Students!

by gwilson on Mar.24, 2009, under A Day in the Life..., Projects

chlamy_in_phototaxis_tube1This spring, Dr. Tom Benoit is teaching BIMS 1101 Unicellular Organisms Lab.  It is a standalone lab that accompanies the BIOL 1301 Unicellular Organisms Lecture; required for Biomedical Science majors but elective for everyone else.  In its first time taught, the class has become a roaring hit with BIMS students who enjoy the liberty of designing and conducting experiments, recognize the breadth of skills being learned, and appreciate the practical approach to applying knowledge in an experimental setting.

This lab features a “tourist’s view” of the world of one-celled critters.  The course for freshmen started with an introduction to bacteria - students building Winogradsky columns and learning aseptic technique and staining procedures.  From there, students isolated and observed fungi and moved on to protists.  Though many freshman courses show passing interest in one or two of these organisms, it is a rare course that is so completely devoted to their biology.  In BIMS 1101, fundamentals of prokaryotes, fungi, and protists – their cell structure and physiology, taxonomy, and classification – all take center stage under one roof. 

Students love the research-rich approach and hands-on work, due in no small part to Dr. Benoit.  He has divided the class into research teams to conduct experiments, with the prep work of making media and solutions being part of their effort.  As with other BIMS courses, skills build upon skills.  All that has been learned will be put to the test when research teams undertake their final project – the isolation and selection of the fastest Chlamydomonas cultures they can find.  The semester’s main event will be held at the end of April:  Chlamy races, with the winning team being crowned Checkered Flag-ella Champions 2009.  Stay tuned for updates and the outcome!
