Life Science Undergraduate Mentors In Ne Stem 4u Significantly Outperform Their Peers In Critical Thinking Skills, Kari L. Nelson, Claudia M. Rauter, Christine E. Cutucache
Life Science Undergraduate Mentors In Ne Stem 4u Significantly Outperform Their Peers In Critical Thinking Skills, Kari L. Nelson, Claudia M. Rauter, Christine E. Cutucache

The development of critical thinking skills in recent college graduates is keenly requested by employers year after year. Moreover, improving these skills can help students to better question and analyze data. Consequently, we aimed to implement a training program that would add to the critical thinking skills of undergraduate students: Nebraska Science, Technology, Engineering, and Math 4U (NE STEM 4U). In this program, undergraduates provide outreach, mentoring, and science, technology, engineering, and mathematics (STEM) education to K–8 students. To determine the impacts of serving as an undergraduate mentor in this program on critical thinking, we compared undergraduate mentors (intervention group) …

Iron is critical for virtually all organisms, yet major questions remain regarding the systems' level understanding of iron in whole cells. Here, we obtained Mössbauer and EPR spectra of Escherichia coli cells prepared under different nutrient iron concentrations, carbon sources, growth phases, and O2 concentrations to better understand their global iron content. We investigated wild-type cells and those lacking Fur, FtnA, Bfr, and Dps proteins. The coarse-grain iron content of exponentially growing cells consisted of iron-sulfur clusters, variable amounts of nonheme high-spin FeII species, and an unassigned residual quadrupole doublet. The iron in stationary-phase cells was dominated by …
Role Of Genes In Obesity, Hanna Mathew, Mir Saleem
Role Of Genes In Obesity, Hanna Mathew, Mir Saleem
Biology Faculty Articles
Obesity is the outcome of an extreme difference between the energy intake and the energy expended, which leads to severe weight gain. The two main factors of obesity are environmental influences and genetics, but the extent of the genetic contribution to obesity continues to be unknown. Multiple studies using different tools have been used to support the significance of the genetic influence on obesity, such as twin and adoption studies, race/ethnicity, and mouse models. The use of mouse models has allowed for the greatest expansion of knowledge on the genetics behind obesity, and advancements continue to be made to this …
