Free-ranging, juvenile thirteen-lined ground squirrels (Ictidomys tridecemlineatus) in southwestern Michigan were fitted in late summer or fall with external skin-temperature loggers. Data were obtained the following spring for five males and three females. During the heterothermal period, all squirrels exhibited 1122 prolonged ( x̄= 9.4 d) torpor bouts punctuated by typically brief ( x̄= 14.3 h) arousal bouts, with mean monthly torpor bouts becoming longer and deeper until Feb. and reversing thereafter. Torpor-bout duration increased as minimum skin and soil temperatures decreased. On average, males initiated the first torpor bout later in fall, terminated the last torpor bout significantly earlier in spring and thus spent less time in the heterothermal period than did females. Three males displayed relatively short torpor bouts and long arousal bouts as they approached the end of hibernation. Squirrels gained weight variably in fall and spring, and one female lost 39% of body mass during hibernation. © 2012, American Midland Naturalist. Source

Very-long-chain polyunsaturated fatty acids such as arachidonic, eicosapentaenoic, and docosahexaenoic acids, are important to the physiology of many microorganisms and metazoans and are vital to human development and health. The production of these and related fatty acids depends on Δ6 desaturases, the final components of an electron transfer chain that introduces double bonds into 18-carbon fatty acid chains. When a Δ6 desaturase identified from the ciliated protist Tetrahymena thermophila was expressed in Saccharomyces cerevisiae cultures supplemented with the 18:2Δ9,12 substrate, only 4% of the incorporated substrate was desaturated. Cytochrome b5 protein sequences identified from the genome of T. thermophila included one sequence with two conserved cytochrome b5 domains. Desaturation by the Δ6 enzyme increased as much as 10-fold when T. thermophila cytochrome b5s were coexpressed with the desaturase. Coexpression of a cytochrome b5 from Arabidopsis thaliana with the Δ6 enzyme also increased desaturation. A split ubiquitin growth assay indicated that the strength of interaction between cytochrome b5 proteins and the desaturase plays a vital role in fatty acid desaturase activity, illustrating the importance of protein-protein interactions in this enzyme activity. © 2013, American Society for Microbiology.

This project is a partnership between Snohomish School District and Everett Community College. Everett Community College will use facilities provided by Snohomish School District to teach Advanced Manufacturing skills. The partnership will better utilize equipment and facilities, allow middle and high school students access to advanced equipment, provide professional development for teachers and engage young students exciting them to study STEM fields. The opportunities provided by the work will increase the number of students from underrepresented groups who study STEM fields and enter the workforce. Since the local need for manufacturing workers, especially in aerospace, is expected to grow a well educated worker is a critical element to the continued success of the Snohomish County and Regional economy and this work will help ensure these workers are prepared.
The project will increase the number of industry certificate holders in the area of advanced manufacturing by 20%, increase the number of associate degree holders with experience in advanced manufacturing by 100% and increase the number of community college transfers to a four-year institution by 15%.
The applied learning/training in the program will increase student scientific literacy and provide more opportunity to be creative and create connections to business and industry making study more relevant and focused. The projects dual enrollment benefits student enrollment and early mentoring and could become a model that can be duplicated nation-wide.

The Aerospace and Advanced Manufacturing (AAM) program at Everett Community College, consisting of Engineering Technology, Machining Technology, Composites Technology and Welding and Fabrication, are being housed in one location to allow students to experience the different processes that occur in the manufacturing world from the stages of ideation to the final assembly of a product. In each of these programs, students are encouraged to broaden their perspectives by taking electives from the different disciplines in the AAM program. A twelve-credit Manufacturing Cycle Curriculum, leading to a certificate in Advanced Manufacturing Essentials, is to be developed. The Curriculum, required of all AAM students, teaches them the full process and essential job duties of manufacturing from the design phase to quality assurance. Students are expected to work on projects that can be feasibly produced in one program and be able to communicate the issues that occur during manufacturing to students in other disciplines. In addition, the AAM faculty work with faculty in mathematics and English to create AAM-context based modules for developmental courses so that students are prepared for the technical courses. In professional development workshops, high school and community college faculty develop modules to engage high school students in learning the STEM content needed for technical programs.
The project funds career coaches to assist high school students and their parents to become aware of technical careers and pathways that include community college. The project also funds a Navigator position to guide at-risk community college students to appropriate services. The evaluation measures the effectiveness of these strategies to recruit, retain and place AAM students and determines their preparation for the requirements of the workplace.
Worker productivity requires that workers not only have technical operation skills, but a broader understanding of how their task relates to both the quantity and quality of the final product. Workers knowledge of the full manufacturing cycle puts their work in context of not only what they do, but why they do it and how their work relates to the companys purpose. The idea of the AAM program is to have the different departments work together to ensure that students understand the entire manufacturing and life cycle processes.

An award has been made to Everett Community College to organize a program of self assessment for life science departments as part of the mission of the Partnership for Undergraduate Life Science Education (PULSE). In September 2012 the PULSE partners (HHMI, NIH, and NSF) appointed 40 Vision and Change Leadership Fellows to stimulate transformative changes in undergraduate life science education as recommended in the Vision and Change report. Fellows were selected from two-year colleges, liberal arts colleges, comprehensive universities and research universities. The Fellows have organized into working groups with the overarching goal of helping departments transform their programs in a national effort to increase student learning of core concepts, increase student retention in the sciences, and prepare all students to be more curious and scientifically literate citizens.
The current award is to begin testing a comprehensive set of rubrics developed by the Taking the Pulse Working Group. The Vision and Change report contained a number of recommendations for improving undergraduate life sciences education but did not furnish an implementation strategy. The rubrics that have been developed will serve as a blueprint for departments to evaluate their own progress in adopting recommendations in the areas of curriculum development, faculty support, student engagement and inclusivity, assessment, infrastructure, and the campus climate for change. The working group also plans to pilot a certification program to both motivate departments to adopt Vision and Change recommendations and to reward departments that have enacted Vision and Change principles. The initial draft set of rubrics has been posted on the www.pulsecommunity.org website under the provisional title: Taking the PULSE Vision and Change Rubrics 1.0 and rubrics will be updated as more departments field-test them at all institution types. Results from the Taking the PULSE project will be posted on the PULSE website and shared with the life sciences community at professional meetings.
This project is being funded jointly by the Directorate for Biological Sciences and the Directorate of Education and Human Resources, Division of Undergraduate Education as part of their efforts to support Vision and Change in Undergraduate Biology Education
