News Article | April 19, 2016
It’s been a while since I featured a citizen science project here at The Artful Amoeba, but I learned of one last week that I think may be of interest to you. It’s called Notes from Nature, and the aim is simply to digitize some of the millions of herbarium and natural history specimen labels squirreled away in smelly cabinets and drawers across the country. This information tells us much about biodiversity, evolution, and climate change, but to be most useful, it needs to live in a form that can be searched by scientists anywhere, not just ones with fat travel budgets. Your job, essentially, is transcriptionist, but your secondary role is voyeur. You get to have a peek at specimens you otherwise would never get to see. You get a glimpse into a past place and time where a person found a mushroom or plant that was of enough interest to them they plucked it from the ground, hauled it back to a university, and took the time to write about what they found. I tried out the format myself. Good: No need to register to help! You can simply start transcribing after reading a short intro. Bad: There is often no way to go back and fix typos, mistakes or omissions on the current platform if you accidentally click “OK” on a field before you are ready. They will be moving to a new platform this summer, however, so let’s hope they fix that issue. It helps if you have a talent for deciphering handwriting, as many of the labels are in longhand and require a bit of puzzling out. It also helps to be willing to do a little detective work. You may need to discover whether a particular phrase is a common plant name, a habitat, or something related to the location. Counties are always required, but counties are not always given on the forms. And counties are not always even used – or have changed since the specimen was collected, as I discovered when trying to transcribe a specimen from remote British Columbia collected in the 1960s, where electoral districts are used and have changed since then. And at least one plant specimen I looked at appeared to have at least two or three different collectors’ names on it. It’s your job to figure out who was the original. As with most citizen science projects, it is a fun way to take a break for a few minutes, blow off some steam, or just get in some good old-fashioned procrastinating time while still doing something constructive for science. Or perhaps you broke a leg and six ribs in a ski accident and are bedbound for three months. Here’s a great way to spend your time, assuming, of course, you still have the use of your hands. The team, as I mentioned, is trying to move to a new platform and website this summer. Before they do, they are trying to get their last fungus and plant collections finished by the end of May – and judging from the website they still have more than 15,000 transcriptions to go. The remaining two are plants from the Southeastern Louisiana University Herbarium and fungi from the Macrofungi Collection Consortium. If you have a few spare moments to donate and are botanically curious, like reading old handwriting, and willing to solve a few small puzzles, check it out!

In this study, the anterior testicular ducts of the North American natricine snake Seminatrix pygaea are described using light and electron microscopy. From the seminiferous tubules, the rete testis passes into the epididymal sheath, a structure along the medial border of the testis heavily invested with collagen fibers. The rete testis consists of simple, nonciliated cuboidal epithelium (principal cells). The intratesticular ducts of the rete testis are narrow (50-70 lm) at their junction with the seminiferous tubules, widen (80-100 lm) as they extend extratesticularly, and divide into smaller branches as they anastomose with the next tubules, the ductuli efferentes. The ductuli efferentes are lined by simple cuboidal epithelium but possess nonciliated principal cells as well as ciliated cells. These are the only ducts in the male reproductive system with ciliated cells. The ductuli efferentes are narrow (25-45 lm), divide into numerous branches, and are highly convoluted. The ductus epididymis is the largest duct in diameter (240-330 lm), and the diameter widens and the epithelium thins posteriorly. The ductus epididymis is lined by nonciliated, columnar principal cells and basal cells. No regional differences in the ductus epididymis are apparent. Ultrastructural evidence suggests that all of the nonciliated principal cells in each of the anterior testicular ducts function in both absorption and secretion. Absorption occurs via small endocytic vesicles, some of which appear coated. Secretion is by a constitutive pathway in which small vesicles and a flocculent material are released via a merocrine process or through the formation of apocrine blebs. The secretory product is a glycoprotein. Overall, the characteristics of the anterior testicular ducts of this snake are concordant with those of other amniotes, and the traditional names used for snakes are changed to conform with those used for other sauropsids and mammals. © 2009 Wiley-Liss, Inc.

States formed by attachment of excess electrons to molecules or clusters can be broadly classified into valence and nonvalence states, but many of these states do have both, some valence and some nonvalence character. Here a new analysis scheme for this type of state is presented. It is based on considering the density of the excess electron as a function of the distance to the nearest atom, and this vantage point yields, in the first place, an intuitive picture akin to the well-known atomic radial distribution function, and, in the second place, a distance-from-the-atoms measure that is directly related to the nonvalence character of the excess electron. As a first test the analysis scheme is applied to the occupied orbitals of the water monomer, the water hexamer, and benzene, and its properties are contrasted to those of other frequently employed measures, such as the radius of gyration. Then its utility is demonstrated for three anions: CH3NO2-, which has both a valence and a nonvalence state, NaCl-, whose ground state has been classified as valence or nonvalence by different authors, and two conformations of the water hexamer anion, (H2O)6, the so-called AA isomer, which supports a surface state, and a Kevan-like structure, which has served as a model for a cavity state. © 2013 American Chemical Society.

The purpose of this mixed-methods pilot study was to explore the feasibility of using Second Life to conduct research and to describe nurses' experiences in using Second Life to facilitate nursing journal clubs. A QUAN→qual sequential design using survey and qualitative methods was used to guide scientific inquiry. Survey data were analyzed using descriptive statistics, and t, Mann-Whitney U, and χ tests were used to test for presurvey and postsurvey group differences. Journal club screencast recordings were thematically analyzed. This study was conducted in an Internet-accessible, 3-dimensional multiuser virtual environment. A convenience sample of registered nurses from 7 facilities consented to participate. Completed data from 29 presurveys and 20 postsurveys were included in data analyses. Overall, nurses reported a benefit in using Second Life to facilitate journal clubs. The Mann-Whitney U test identified (P < .05) improvement in 7 of 8 critical appraisal competencies after journal club activities: determining design, determining population, interpreting statistics, linking findings/conclusions, identifying limitations, identifying implications, and interpreting qualitative findings. Qualitative analyses of screencastings validated reports of improved critical appraisal competencies and identified 3 inworld themes: presence, learning strategies, and learning outcomes. Registered nurse study participants reported a benefit of using Second Life for nursing journal clubs. Participants perceived and demonstrated improvement in critical appraisal competencies. Further research is warranted on outcomes associated with nurses' appraisal of evidence for application to practice using a multiuser virtual environment.

Rapid response to a health epidemic is critical to reduce loss of life. Existing methods mostly rely on expensive surveys of hospitals across the country, typically with lag times of one to two weeks for influenza reporting, and even longer for less common diseases. In response, there have been several recently proposed solutions to estimate a population's health from Internet activity, most notably Google's Flu Trends service, which correlates search term frequency with influenza statistics reported by the Centers for Disease Control and Prevention (CDC). In this paper, we analyze messages posted on the micro-blogging site Twitter.com to determine if a similar correlation can be uncovered. We propose several methods to identify influenza-related messages and compare a number of regression models to correlate these messages with CDC statistics. Using over 500,000 messages spanning 10 weeks, we find that our best model achieves a correlation of .78 with CDC statistics by leveraging a document classifier to identify relevant messages.

With this award from the Major Research Instrumentation Program that is co-funded by the Chemistry Research Instrumentation and Facilities (CRIF) Program, Professor Debra Dolliver from Southeastern Louisiana University and colleague Jean Fotie will acquire a 400 MHz NMR spectrometer. The proposal is aimed at enhancing research and education at all levels, especially in areas such as (a) development of synthetic techniques to make single geometric isomers of imine derivatives; (b) design and synthesis of biologically active molecules as potential antiprotozoan agents; (c) support of the program SEAL (Student Entrepreneurs as Active Leaders) Research in Physics; (d) modeling atomic and molecular properties, particularly those occurring under the influence of electric, magnetic, and electromagnetic perturbations; and (e) synthesis of of thiophene-based room temperature ionic liquids and the testing of such ionic liquids as media for organic synthesis.
Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solution. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. The results from these NMR studies will have an impact in synthetic organic/inorganic chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research.

Thomas Sommerfeld of Southeastern Louisiana University is supported by an award from the Chemical Theory, Models and Computational Method program in the Chemistry Division and the NSF EPSCoR office to investigate how extra electrons aid in breaking chemical bonds. Chemical bonds themselves are electrons shared between atoms and can be thought of as a glue holding the atoms in a molecule together. The electron-glue analogy, however, only goes so far, because a bond can be weakened by both too little and too much glue, and weak bonds can be cleaved during the permanent motion of the atoms. In other words, adding an electron to a molecule generally weakens its bonds, and the resulting so-called temporary anion may undergo either bond cleavage or, alternatively, reemit the extra electron. Concrete examples where this reaction is applied or happens naturally are: plasma chemistry and plasma etching, chemistry in the ionosphere, damage to living tissue by ionizing radiation, cancer therapy with electron beams, and reduction reactions with solvated electrons, the so-called Birch reduction. This research project supports the development of computer models of the temporary anion, the first intermediate formed in these electron-induced reactions. This research is carried out with collaborators and with undergraduate researchers. In order to introduce undergraduates to this research, Dr. Sommerfeld also designs educational mini-projects, which are only indirectly related to the current main project, but can be addressed with standard quantum chemistry methods, so that his students can be introduced to the research area step-by-step.
In this project Dr. Sommerfeld studies electronically metastable states - so called resonance states or, simply, resonances. On the one hand, he develops ab initio methods to characterize resonances, and on the other hand he applies the newly developed methods in selected applications. Computing both the energy and finite lifetime of a resonance is still a notoriously challenging task for quantum chemistry, because it combines an electron-scattering with an electron-correlation problem. To address the continuum aspect, Dr. Sommerfeld either uses complex-absorbing-potentials or the analytic-continuation-in-the-coupling-constant method. To address the correlation aspect, he uses the symmetry-adapted-cluster configuration-interaction method, an electronic structure method closely related to the equation-of-motion coupled-cluster method. One particular point of emphasis is the artificial stabilizing potential added to the Hamiltonian in the analytic-continuation-in-the-coupling-constant method. Dr. Sommerfeld aims to identify a short-range stabilizing potential that improves the subsequent analytic-continuation step. On the application side Dr. Sommerfelds goals are to examine resonance states, which differ in electronic structure from a closed-shell neutral either by one-hole (Auger-like resonances) or by one excitation (e.g. Penning ionization or resonant photodetachment). For these resonances, treating electron correlation in a balanced way is particularly challenging. Dr. Sommerfeld studies temporary anion resonances embedded in small molecule clusters with the goal of identifying trends in the change of the resonance parameters associated with the interaction strength (permanent dipole, higher order multipoles, dispersion) of the embedding molecules.

The Cyprinodontiformes, commonly known as splitfins, are a diverse order of teleost fishes consisting of 10 families, and more than 800 globally distributed species. The group includes killifishes, guppies, and swordtails, and is well known among aquarium hobbyists, toxicologists, and as a model organism in cancer research. Goodeids are an imperiled group of freshwater fishes that occur in Mexico and the Southwestern United States and consist of two main lines of diversification; a depauperate group of egg laying species, and a speciose group that bear live offspring. Many groups in the order, including the viviparous (live birthing) species, are understudied from an ecological and evolutionary perspective.The evolutionary relationships of groups within the order are unclear and the relationships of the species and genera within the Goodeidae family have not been adequately studied. The lack of a robust family tree has impeded both basic and applied research on the splitfins. Resolving the evolutionary relationships within the Cyprinodontiformes, as well as within the Goodeidae species, will advance our understanding of life-history evolution, morphological diversification, taxonomy, and conservation. The researchers will write a handbook for aquarists and conservation biologists containing recommendations for maintenance and breeding guidelines for maintaining genetic and phenotypic diversity of goodeids in captivity. The researchers will work with the Goodeid Working Group to update the Goodeidae conservation status and trends information as well as contribute to aquarist-oriented publications and conventions to promote appropriate captive Goodeidae rearing. These efforts will enhance conservation efforts of these fishes which are critical to resource managers especially considering the ongoing environmental changes in the areas occupied by the Goodeidae.
This integrative project will involve multiple graduate and undergraduate students, international and United States collaborators, and citizen scientists. Specimens will be collected in the United States and Latin America and the vouchered tissue samples, which are important for future studies, will be deposited in research collections in the United States and Mexico. Citizen scientists will provide pedigreed larval specimens of all species of Goodeidae. These are historically difficult to obtain and will be used for scanning electron microscopic examination of trophotaeniae, a poorly understudied larval taxonomic character that is critical to the unusual live births in this group. This study will result in the construction of phylogenetic trees for the Cyprinodontiformes and the Goodeidae based on traditional (10 loci, and >7,000bp sequence data) and next generation sequencing approaches (anchored phylogenomics), offering the most comprehensive tests of previous phylogenetic hypotheses for these groups. The incorporation of geometric morphometric and trophotaenial data, fossil calibrations, and phylogenetic comparative methods will allow for a better understanding of the timing of diversification and the factors that have played a role in radiation of this interesting group of fishes. Finally, the research will assess changes in Goodeidae abundance and distribution, based on museum records and field sampling.

In this project funded by the Chemical Synthesis program of the Chemistry Division, Professor Debra Dolliver of the Department of Chemistry & Physics at Southeastern Louisiana University, in collaboration with Professors Kevin Shaughnessy and Professor Timothy Snowden from the University of Alabama, Tuscaloosa, will study synthetic methodology to produce N-heteroatomic imines in single geometries and applying these compounds for the synthesis of asymmetric amines. There are three specific aims: 1) to investigate the palladium-catalyzed coupling of N-heteroatomic-substituted imidoyl halides with a variety of coupling partners; 2) to initiate studies to reverse the role of the imine species in Pd-catalyzed coupling reactions from that of the organohalide to that of the organometallic reagent by synthesizing an N-heteroatomic imidoyl metal compound; and 3) to synthesize geometrically-controlled N-heteroatomic imine derivatives containing an asymmetric center in the heteroatomic group attached to nitrogen and investigate facial selectivity of these compounds to nucleophilic addition.
This project has significant impacts on fundamental biological sciences, pharmaceutical and agricultural industries, as it would provide ready access to chiral amines important in the chemical synthesis of complex molecules of potent biological activities. The project also provides trainings for undergraduate students in preparation for careers in the physical science fields, which is very significant considering the high percentage of first generation college students and groups underrepresented in the physical sciences at the PIs institution.
