FEDERAL AGENCY ACTIVITIES
ADVANCE: Increasing the Participation and Advancement of Women in Academic Science and Engineering Careers
The goals of the ADVANCE program are (1) to develop systemic approaches to increase the representation and advancement of women in academic STEM careers; (2) to develop innovative and sustainable ways to promote gender equity in the STEM academic workforce; and (3) to contribute to the development of a more diverse science and engineering workforce. ADVANCE also has as its goal to contribute to and inform the general knowledge base on gender equity in the academic STEM disciplines. There are three tracks with distinct purposes. The Institutional Transformation (IT) track is meant to produce large-scale comprehensive change and serve as a locus for research on gender equity and institutional transformation for academic STEM. The Institutional Transformation Catalyst (IT Catalyst) track is meant either to conduct self-assessment or to implement unique strategies – either adapted from those found effective in the IT track or ones designed to be responsive to the unique environments of eligible institutions – and evaluate their effectiveness. The Partnerships for Learning and Adaptation Networks (PLAN) track is meant to provide a larger scale environment for adapting, implementing and creating knowledge about the effectiveness of a particular strategy for change within a context of networked adaptation and learning. PLAN is focused on adaptation/implementation and learning either in particular STEM disciplines (PLAN D) or across institutions of higher education (PLAN IHE). Letters of intent are due August 11, 2014, and more information is available at http://nsf.gov/pubs/2014/nsf14573/nsf14573.htm.
Faculty Early Career Development (CAREER) Program
CAREER: The Faculty Early Career Development (CAREER) Program is a Foundation-wide activity that offers the National Science Foundation's most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations. Such activities should build a firm foundation for a lifetime of leadership in integrating education and research. NSF encourages submission of CAREER proposals from junior faculty members at all CAREER-eligible organizations and especially encourages women, members of underrepresented minority groups, and persons with disabilities to apply.
PECASE: Each year NSF selects nominees for the Presidential Early Career Awards for Scientists and Engineers (PECASE) from among the most meritorious recent CAREER awardees. Selection for this award is based on two important criteria: 1) innovative research at the frontiers of science and technology that is relevant to the mission of the sponsoring organization or agency, and 2) community service demonstrated through scientific leadership, education or community outreach. These awards foster innovative developments in science and technology, increase awareness of careers in science and engineering, give recognition to the scientific missions of the participating agencies, enhance connections between fundamental research and national goals, and highlight the importance of science and technology for the Nation’s future. Individuals cannot apply for PECASE. These awards are initiated by the participating federal agencies. At NSF, up to twenty nominees for this award are selected each year from among the PECASE-eligible CAREER awardees who are most likely to become the leaders of academic research and education in the twenty-first century. The White House Office of Science and Technology Policy makes the final selection and announcement of the awardees. Full proposals are due July 21, 2014, and more information is available at http://nsf.gov/pubs/2014/nsf14532/nsf14532.htm.

Interventions for Health Promotion and Disease prevention in Native American Populations (R01)
The purpose of this funding opportunity announcement (FOA) is to develop, adapt, and test the effectiveness of health promotion and disease prevention interventions in Native American (NA) populations. NA populations are exposed to considerable risk factors that significantly increase their likelihood of chronic disease, substance abuse, mental illness, oral diseases, and HIV-infection. The intervention program should be culturally appropriate and promote the adoption of healthy lifestyles, improve behaviors and social conditions and/or improve environmental conditions related to chronic diseases, the consumption of tobacco, alcohol and other drugs, mental illness, oral disease, or HIV-infection. The intervention program should be designed so that it could be sustained within the entire community within existing resources, and, if successful, disseminated in other Native American communities. The long-term goal of this FOA is to reduce mortality and morbidity in NA communities. For the purposes of this FOA Native Americans include the following populations: Alaska Native, American Indian, and Native Hawaiian. The term ‘Native Hawaiian’ means any individual any of whose ancestors were natives, prior to 1778, of the area which now comprises the State of Hawaii. Letters of intent are due April 12, 2015, and more information is available at http://grants.nih.gov/grants/guide/pa-files/PAR-14-260.html.

Postdoc at University of Guelph
A postdoctoral position is immediately available in the Smith lab at the University of Guelph (Ontario) in the application of DNA-based diagnostics in the early detection of species involved in predating upon the spruce budworm (SBW). In particular, experience in the design and implementation of microarrays is necessary. Applicants should have a Ph.D. and extensive training and experience in one or more of the following areas: DNA extraction, PCR, qPCR and microarray development. The ideal candidate will also have broad training in evolutionary biology, strong writing skills, and prior management experience. The successful applicant will play a key role in a recently funded project to develop and apply new methods involving DNA-based diagnostics for the rapid identification natural enemies of the spruce budworm in New Brunswick. The spruce budworm (SBW - Choristoneura fumiferana) is the major coniferous forest pest in eastern North America. The goal of this project is to design a DNA-based diagnostic for these critical, but difficult to quantify and identify the complement of natural enemies (insect parasitoids and pathogens) that act as natural control agents. To do so, we will adapt, and augment, the existing library of DNA barcodes (small, standardised gene sequences) into a DNA microarray chip enabling us to rapidly identify and quantify the many organisms that interact directly (> 100 species of natural enemies) and indirectly (other conifer-feeding species that serve as alternate/alternative hosts of SBW parasitoids) with the spruce budworm and form the so-called “spruce budworm food web”. Interested applicants should submit a CV, a letter describing their research interests and career goals, and contact information for two references to Dr. Alex Smith (firstname.lastname@example.org). Further information on my research interests and publications can be found at: http://www.uoguelph.ca/~salex/ and on Google Scholar http://scholar.google.ca/citations?user=i5jERHcAAAAJ&hl=en.

Postdoctoral positions in Plant Pathology, Ecology and Metagenomics in agricultural soils Agriculture and Agri-Food Canada (AAFC), Fredericton, New Brunswick (Canada)
Postdoctoral positions in Plant Pathology, Ecology and Metagenomics in agricultural soils Agriculture and Agri-Food Canada (AAFC), Fredericton, New Brunswick (Canada) is looking for candidates for two postdoctoral fellowship positions of three years, to understand factors influencing the severity of common scab of potato. Common scab is a bacterial disease responsible for important economic losses every year and there is still no reliable method to control the disease. This is due to a poor understanding of the dynamic of the pathogenic Streptomyces population, of the influence of agricultural practices and of the biotic and abiotic factors influencing the severity of common scab. The project’s overall goal is to develop innovative control methods for common scab of potato. The specific objectives of the project are 1) to measure the effect of biopesticide and agricultural practices on common scab (position 1) and 2) to compare the biotic (microbial communities using metagenomics) and abiotic (edaphic and environmental) factors between healthy and common scab infected fields (position 2). Applicants should have experience in plant pathology, molecular biology and next generation sequencing of microbial communities (position 2). Knowledge of English is required. The candidate needs to be Canadian citizen or permanent resident and meet the criteria of the NSERC Visiting Fellowship in Canadian Government Laboratories Program (http://www.nserccrsng.gc.ca/Students-Etudiants/PD-NP/Laboratories-Laboratoires/index_eng.asp ). The position will be opened until filled; suggested start date is September.

SPOTLIGHT ON MINORITY MICROBIOLOGISTS
Maria E. Cardenas, Ph.D., Research Professor, Department of Molecular Genetics and Microbiology, Duke University Medical Center, Durham, NC.
The evolutionarily conserved TORC1 pathway controls growth in response to nutrients, in particular amino acids, and is perturbed in diseases such as cancer and diabetes. Key components of the endolysosomal membrane trafficking system have been implicated in the regulation of TORC1 signaling in both humans and yeasts. Two protein complexes collectively called VPS-C complexes, HOPS and CORVET, mediate distinct membrane fusion events in the endolysosomal trafficking system. Disruption of VPS-C complexes in yeast leads to fragmentation of vacuoles, the equivalent of lysosomes in mammals, and to severe defects in TORC1 signaling. The vacuole is a major amino acid reservoir and the TORC1 machinery resides on the vacuolar membrane. We demonstrate that the HOPS and CORVET complexes promote TORC1 activity by maintaining amino acid homeostasis in yeast. Given the ubiquity and pervasive conservation of TORC1 signaling across eukaryotes, these findings suggest ways in which cell growth may be controlled in metazoans and other multicellular eukaryotes. Thus, understanding the roles for the yeast endolysosomal membrane system in TORC1 signaling will provide therapeutically relevant insights in dysregulated mTORC1 defects that underlie disease in humans.
Recent featured publication: Endolysosomal membrane trafficking complexes drive nutrient-dependent TORC1 signaling to control cell growth in Saccharomyces cerevisiae. Kingsbury JM, Sen ND, Maeda T, Heitman J, Cardenas ME. Genetics. 2014 Apr;196(4):1077-89. doi: 10.1534/genetics.114.161646.
Maria E. Cardenas, Ph.D. is a Research Professor at Duke University Medical Center. Her studies focus on elucidating the mechanisms of activation and signaling of the Tor kinases. Tor was discovered in Saccharomyces cerevisiae as the target of the immunosuppressive and anticancer drug rapamycin. Rapamycin has widespread applications in several clinical arenas including organ transplantation, cancer chemotherapy, and cardiology, and might find additional indications in cognitive disease and aging-related disorders. Dr. Cardenas received a MS degree from the National University of Mexico and a Ph.D. from the University of North Texas training with Dr. Myron Jacobson. She learned genetics and chromatin structure as a postdoctoral fellow with Drs. Susan Gasser (ISREC, Lausanne, Switzerland) and Titia de Lange (The Rockefeller University). She was elected a fellow of the American Association for the Advancement of Science (AAAS) in 2011.
At Duke her studies led to the characterization of the transcriptional programs governed by the TORC1 cascade and its contribution to filamentous growth in yeast and other fungi. More recently, she employed yeast to characterize the genetic synthetic interaction network of TOR1. These studies uncovered a novel role for the endomembrane vesicular trafficking system in regulating TORC1 signaling. She found that cell growth is compromised or abolished when mutations in different protein complexes including the VPS-C, preautophagosomal (PAS), and EGO (EGOC) involved in vesicular trafficking and tethering, and protein sorting are combined with a mutation of the nonessential Tor1 kinase. The EGOC and orthologs of its GTPase subunits (Rag proteins) are implicated in amino acid-dependent TORC1 activation in yeast and mammals. Current studies focus on characterizing the roles of the vesicular trafficking system in TORC1 signaling and to elucidate the molecular mechanism by which the VPS-C and EGOC complexes convey amino acid signals to evoke TORC1 activation. TORC1 pathway components are localized to vacuolar membranes. Her hypothesis is that this endomembrane network serves as a platform to facilitate molecular interactions that activate and enable TORC1 signaling. Similar to yeast TORC1, the mammalian mTORC1 ortholog targeted by rapamycin and its analogs in the treatment of multiple cancer malignancies is localized to endomembranes. Thus, her studies will continue to reveal fundamental basic and conserved aspects of Tor signaling that could serve as a guide to pharmacological intervention in select mTor pathway defects.
In July 2006, the Committee on Microbiological Issues Impacting Minorities (CMIIM) of the American Society for Microbiology Public and Scientific Affairs Board developed a monthly e-newsletter which contains information pertinent to minority microbiologists. Currently, there are very few minority-based newsletters for scientists, and there are none for microbiologists.
This e-newsletter provides a central means of distributing pertinent information to underrepresented minorities in the field of microbiology. Some examples include career advice, networking tips, relevant news articles, unique funding and career opportunities, microbiological issues affecting minorities (e.g., HIV), minority issues affecting microbiologists (e.g., minority retention), and scientific articles published by minorities or by minority-serving institutions (MSIs).
The target populations are African-Americans, Latino-Americans, Native Americans, Alaska natives, and Pacific Islanders; however, all ASM members are invited to sign up and to share this information with others who may find this e-newsletter beneficial.
Signing up to receive The Minority Microbiology Mentor is very easy and is open to ASM members and non-members: simply go to http://asm.org/index.php/component/content/article/31-forms/forms/238-subscribe-to-listserv, enter your email address, and select "MinorityMicroMentor" then submit, and you will receive confirmation of your subscription by email. If you are an ASM member, you will be prompted to Log In before signing up.
The Committee on Microbiological Issues Impacting Minorities is chaired by Dwayne W. Boucaud, Ph.D., Professor in the Quinnipiac University Department of Biomedical Sciences in Hamden, CT. The Minority Microbiology Mentor Editor-in-Chief is Dr. Floyd L. Wormley Jr., Ph.D., Associate Professor at the University of Texas at San Antonio and the Associate Editor is Crystal N. Johnson, Ph.D., Assistant Professor at Louisiana State University in Baton Rouge, LA.
