07270327If you have never been to Mesa Verde, you cannot imagine how majestic and awe-inspiring this world heritage treasure is.  It represents the most amazing collection of artifacts of a lost civilization that one can imagine. 

One of the key elements of the BIMS program is establishing for graduate programs and professional schools our own collection of artifacts to testify to the strengths and abilities of our students.  The BIMS program participates in routine assessment of student and program success.  We want to document proof of effectiveness in providing students with useful and marketable knowledge and skills, and proof that our courses are effective in meeting the program’s goals.  Our flyers for the BIMS program (see BIMS Downloads at the top of this page) outline three lines of evidence (”artifacts”) our students will have of their knowledge and abilities:

  • The biological portfolio of biological products (their personally isolated and identified strains of bacteria, proteins and other products of assays and extractions done in lab, gels and other artifacts of productivity in the lab),
  • The electronic portfolio (posters of their research, reports, digital photographs and micrographs, etc. – artifacts of their analysis and reporting to the scientific community), and
  • Their performance on the BIMS 4000 Junior Exam. 

April 5th marks the day the BIMS 4000 Junior Exam is made available to our junior students.  It consists of basic, intermediate, and advanced questions over the program goals covered in each of the freshman and sophomore courses: 

  • Intro to Scientific Research,
  • Unicellular Organisms,
  • Microbiology,
  • Human Physiology, and
  • Genetics.

Here’s a sampling of three questions students might find as they take this exam…

Means used for preserving foods and increasing their shelf life typically include
A. Acidification to prevent fungal growth
B. Addition of salt or sugar to lower the pH of the foodstuff
C. Removal of available water and addition of acids
D. Pasteurization to sterilize the foodstuff
E. More than one of these

The germ layer from which the skeletal muscles, heart, and skeleton are derived is the
A. Ectoderm
B. Mesoderm
C. Endoderm
D. Notochord

Within the same individual, some genes mutate at a much higher rate than other genes.  This is because
A. Some genes are larger than others providing a greater chance for mutation
B. Some genes have hot spots, which are locations that make them more susceptible to mutation
C. Some genes are larger than others, which prevents DNA polymerase from incorporating the incorrect base during replication
D. A and B
E. B and C

The answer for one of these is A, for one is B, and for one is C.  We’ll let you figure out which is which! :-)   Or, you can find a BIMS major and ask them for a little help.  May your artifact from these three questions match the artifact they will develop as they complete the exam!

Public Health

by gwilson on Feb.28, 2010, under A Day in the Life...

Gram negative rodsThe vision of the Biomedical Science program at McMurry is to teach biology from the perspective of molecules, cells, and human health.  It is often easy to see the emphasis on molecules and cells.  We have courses like Genetics, Microbiology, Human Physiology.  However, we are never far from a discussion of how these elements of biomedical science influence human health and wellness.  To say one does not go without the other would be a fair statement.

I believe our focus on human health really contributes well to understanding the concept of public health.  Public health can be seen in a variety of ways.  Most obvious would be the emphasis on healing the sick or preventing illness.  Our courses focus on these elements as we study how life works, what happens when it doesn’t work well, and how man has contributed to rectifying the problems to restore health.  Less obvious, but no less important, is the need for us to consider exercise and wellness and health policy and administration and education when we consider health and wellness of individuals AND communities.  When expanded in these ways, such things as promoting active lifestyles, dietary awareness, food safety, veterinary health care, and mental health all contribute to a more comprehensive understanding of what constitutes public health.  Limiting ourselves to consideration of DNA and drugs and cells and microbes severely restricts and underestimates the concept of health in all its dimensions.

 McMurry’s BIMS program represents one of the keystones for a comprehensive approach to teaching public health and safety on our campus.  The Department of Kinesiology’s Exercise Science & Human Performance program is an excellent partner, along with the Department of Psychology’s focus on mental health.  Who knows – maybe one day we will borrow from these and other areas of campus to build a bona fide Bachelor’s degree in Public Health!

Spaces for New Programs

by gwilson on Oct.16, 2009, under A Day in the Life...

blueprintSeveral years ago, Dr. Russell laid out his vision for McMurry’s future in a speech entitled Vision 2023 .  Central to that vision was an emphasis on growth of the sciences and their importance in preparing our graduates for jobs of the future.  Biology responded to the challenge of building new and relevant programs for life sciences by developing three new, more focused programs.  One of these is the BIMS program. 

At the same time, the McMurry Capital Campaign, Shaping the Future, has a focus on supporting spaces for the sciences.  These two developments led to a competition on campus this fall where programs were challenged with proposing new spaces to fit their new programs and help make their delivery more effective and efficient.  Thought was that an invitation to develop a variety of science building proposals would provide a excellent collection of projects that could be shopped to potential donors to help improve all science programs.  Biology submitted two lab renovation proposals, one of which was heavily geared toward improving spaces for BIMS courses.

The BIMS proposal calls for several improvements, including renovating and expanding spaces now used for teaching molecular biology and microbiology courses.  The current spaces, S115 and S102, are home to labs (and sometimes lectures) for Genetics, Molecular Biology, Advanced Bioscience Techniques, Unicellular Organisms, Intro to Scientific Research, Microbiology, Immunology, and Senior Capstone Research.  Obviously, such heavily used spaces are unusual on any campus and thus pose challenges to effective and efficient delivery, especially in a research-oriented approach to teaching.  Renovating these spaces to better meet the needs of all students in these various courses is a challenge worthy of lab renovation.

In the competition, a Physics proposal and the BIMS proposal were chosen for funding.  The Trustees meet this weekend and hopes are they will approve expenditure of $2.5M from the Capital Campaign to fund the renovation projects.  If so, planningand design will begin immediately and the renovation will start in May to be completed before the Fall 2010 semester. 

Here is what the BIMS proposal consists of:  more flexible spaces that will support both lecture and lab, anterooms for equipment and incubation and project setup so students can work on their projects outside of their normal hours without interefering with other classes using the teaching spaces, a common equipment area for major pieces of equipment that might be used by students in either lab, special spaces for working with RNA and tissue culture, and possibly additional offices and student space for study, group work, and “hanging out”.  Our hope is our students will become citizens of the building and not simply tourists, that thinking and acting like scientists will give all our BIMS graduates a leg up on those who have gone through conventional and impersonal science programs.
