McMurry’s spring semester is underway and classes for Biomedical Science majors continue to draw interest from students and campus leaders. The BIMS 1300 Intro to Scientific Research course is filled beyond capacity. Taught by Dr. Wilson, students will explore what science is, how scientists work, and how the methods of science influence all of society. For instance, next week students will watch a video on the design firm IDEO and explore the basic science, applied science, engineering, and design that have gone into a variety of consumer products.
Dr. Benoit is teaching BIOL 1301 Unicellular Organisms to a healthy number of students. Their semester-long project will investigate protozoans and will culminate with identification, characterization, and photomicrography of single-celled organisms. This has proven to be a very popular and interesting class for new freshmen, and sets the stage well for a degree program filled with hands-on exploration of biomedical topics.
BIOL 3410 Microbiology is also filled to capacity and BIOL 3430 Human Physiology has a healthy enrollment. Both are part of the sophomore sequence for all BIMS majors. Dr. Wilson’s Micro course will feature lab projects looking at the microbial census of student cars, microbes in fresh foods, and viruses from the soil. As always, the focus is on learning knowledge and skills by jumping into research projects – students work as scientists to learn about microbiology. Dr. Sharp’s Human Phys will use a mixture of computer sims and hands-on biometrics to explore the workings of the human body.
Also being taught this semester is BIMS 4391 Advanced Microbiology. Dr. Wilson is leading five students on a quest to isolate and identify endospore-forming bacteria that produce antibiotics. Students will then produce the product using new benchtop fermenters and characterize the antibiotic product physically and chemically. The class is also considering a jaunt down to T-Bar-M ranch for the Spring Meeting of the Texas Branch of the American Society Microbiology, which emphasizes graduate and undergraduate research. ROAD TRIP!
Another unique feature of the BIMS program is the BIMS 4000 Junior Exam course, where students take a departmental diagnostic exam over their first two years of courses to help assess their learning to this point and to help the department assess the effectiveness of its courses in teaching fundamental information. The five students signed up for the course may take this online exam as often as needed to achieve a passing grade.
Finally, several students are engaged in capstone research this semester with Drs. Benoit and Wilson. They will be ramping up the YES assay for detecting estrogen-like compounds in environmental samples of water and soil. We’ve challenged them with developing the protocols for use on campus and developing the standard curve for the assay, then begin testing on some samples from area surface and ground waters.
So, it is a busy time for a healthy program. Bright students have chosen our unique approach to education and are thriving in the hands-on environment.
Students in my Microbiology class this fall have a treat in store. Instead of disconnected labs to teach the main principles of aseptic technique and identifying bacteria, students in this course are going to learn by doing research. I have planned five research projects the student research teams will undertake: conducting an air quality survey of campus buildings, screen fresh vegetables and fruits for E. coli, search for methicillin-resistant Staphylococcus aureus (MRSA) on campus, isolate endospore-formers and their bacteriophage from nature, and have groups design and conduct a research study of their own using the knowledge and skills learned.
One of these represents a first for our students – the MRSA study. Our plan is to obtain nasal swabs from around 100 students on campus and compare the frequency of Staphylococcus aureus (SA) and MRSA among groups and with previous reports nationally. Student research groups will collect nasal swabs and screen for SA and MRSA, identifying the most interesting isolates using our BD Crystal(TM) Rapid ID system. They will analyze the data from a survey of participants and the results from the lab to see if on-campus residents differ in SA/MRSA occurence from off-campus residents, athletes vs. non-athletes, etc. The results should be interesting!
Because we will be doing research involving human subjects, special approval is required from the campus oversight group: the Institutional Review Board, or IRB. Their job is to review proposed campus research to make sure it is ethical, responsible, and conforms to national standards for acceptable scientific research. It is a first for me, since my lab research is typically environmentally-focused (bacteria don’t have to give informed consent!). The “homework” required for the IRB is extensive – several federal reports and statutes to review, an online course through NIH for certification of training (yes, I missed a question!), and then a form that asks all the hard questions needed to insure the research is well-thought, useful, and safe for all. Reading the prescribed materials, thinking through how the project was structured in light of the training, going through the NIH course, and filling out the form took me the better part of three days.
This bunny trail has been educational and informative, so much so that I’ll have all the Microbiology students go through the online training before they start the study in late September. To know the trouble our scientific community goes through to protect the rights and dignity of its individuals is eye-opening and reassuring. Sometimes things of great educational benefit are not on the main thoroughfares of our courses. Oh, and ask those college sophomores you know whether they’ve done anything as exciting as this in their science classes!
