September 3, 2014 Image Caption: To positively affect the participation differences in large classes, researchers from Arizona State University and University of Washington recommend using a pre-sorted list of student names to randomly call on them, rather than allowing students to raise their hands. The research team says that while students may be resistant to the method at first, it is a more equitable way to structure classroom discussions. Credit: Sandra Leander Sandra Leander, Arizona State University Identifying forces behind inequities important next step Science, technology, engineering and mathematics (STEM) fields are traditionally heavily dominated by males, which is of great concern to universities as they try to improve student retention and achievement. One exception to that trend is in the field of biology. Of undergraduate biology majors, more than 60 percent are female, and about half of biosciences graduate students are women. Given that, a common assumption is that biology is one STEM field that no longer faces gender inequalities. However, researchers with Arizona State University and the University of Washington have proven otherwise. In the largest known analysis of gender differences in introductory college-level biology courses, researchers have found evidence of gender-based gaps in both achievement and class … Continue reading →

PUBLIC RELEASE DATE: 2-Sep-2014 Contact: John P. Wikswo john.wikswo@vanderbilt.edu 615-343-4124 Society for Experimental Biology and Medicine The Annual Thematic issue of Experimental Biology and Medicine that appears in September 2014 is devoted to "The biology and medicine of microphysiological systems" and describes the work of scientists participating in the Microphysiological Systems Program directed by the National Center for Advancing Translational Sciences (NCATS) of the National Institutes of Health (NIH) and funded in part by the NIH Common Fund. The Defense Advanced Research Projects Agency (DARPA) and the Food and Drug Administration (FDA) are collaborating with the NIH in the program. Fourteen of the research teams supported by the program have contributed papers and represent more than 20 institutions, including Baylor College of Medicine, Columbia University, Cornell University, Duke University, Johns Hopkins University, Massachusetts General Hospital and Harvard Medical School, the Massachusetts Institute of Technology, Northwestern University, Nortis, Inc., the University of California, Irvine, the University of Central Florida, the University of Pennsylvania, the University of Pittsburgh, the University of Texas Medical Branch, and Vanderbilt University. Dr. John P. Wikswo, founding Director of the Vanderbilt Institute for Integrative Biosystems Research and Education and Editor of the Thematic Issue, explains in his … Continue reading →

In a report published in the Journal of Leukocyte Biology scientists show that macrophages from the lungs of old mice had different responses to Mycobacterium tuberculosis than macrophages from young mice, but these changes were reversed by ibuprofen. "Inflammation in old age can have significant consequences on immune function," said Joanne Turner, Ph.D., a researcher involved in the work from the Department of Microbial Infection and Immunity and Center for Microbial Interface Biology at The Ohio State University in Columbus, Ohio. "With this knowledge, it may be possible to reduce or prevent some diseases in the elderly by decreasing inflammation with diet, exercise and/or drugs." To make this discovery, scientists measured inflammatory markers in the total lung or within purified macrophage populations of young healthy mice and of old healthy mice. Inflammatory markers were elevated in old mice, and isolated macrophages from both old and young healthy mice responded differentially to infection with Mycobacterium tuberculosis in vitro. This suggests that the altered interactions with … Continue reading →

Last week, students enrolled in Ecology, a required course for Biology majors, were treated to a presentation on reptiles and amphibians common to natural areas of East Georgia State College by public safety officer Jason Kohler, aided by library assistant Tia Morris. Kohler described the natural history of several species of snake, lizard, salamander, frogs and toads that biology students may find while conducting experiments on campus. Kohler is also a successful snake breeder and handler, and he brought with him several nonvenomous snakes for demonstration purposes. This type of interaction benefits the students by allowing hands-on experience in a controlled environment. Our biology students maintain a long-term research project on reptile and amphibian activity at several sites on campus, said Dr. Breana Simmons, Associate Professor of Biology. Designed by students under the guidance of GA DNR scientist Dr. Jessica McGuire, this monitoring effort has allowed previous undergraduates to present research results at the Georgia Academy of Sciences annual meeting. Long-term data collection is critical to ecosystem science, but the opportunity to keep these projects going is often limited due to time and budget constraints, Simmons said. These students arent just learning about ecology, they are doing real science and … Continue reading →
