Indulging in nostalgia... the old Physics Reading Room and Kettering Science Library

Before the Science Center was constructed, the Physics Reading Room existed in the northeast corner of the second floor of Wright, and the Class of 1904 Science Library was crammed into the southeast corner of the first floor of Kettering (in the Chemistry wing of Kettering, razed after the north wing of the Science Center was completed).  Every summer, we were devoted to the tasks of preparing thousands of journal volumes for binding, transferring an equal number of older volumes to the old Carnegie Library for off-site storage, shifting the remaining collections and shelving the newly bound journal volumes on their return.  As the number of print subscriptions has dwindled from 365* to 65 (thereabouts), we are freed of the tyranny of shifting, always shifting, and the tedious labor of wheeling very full book trucks across the street, navigating doors, uneven sidewalks and thresholds, to maneuver in the elevator and the dark, musty stacks of Carnegie.  The Science Center is the perfect home for today's consolidated Science Library.  Come enjoy our lovely setting and peruse the new book area.  So many new books arrived in June!

*Why the decrease in print subscriptions?  They're all online, and oh so convenient.  We keep a core of titles in print that are really helpful for browsing - for learning awesome stuff about things you didn't know you didn't know.  It's a very different experience than simply finding that for which you're searching.  Pick up something new and you're sure to encounter a new idea, a fresh perspective, a spark for your imagination.  See you soon.

Too many to describe, come look!

The annual flood of new books arrived with the first week of June, as usual.  There are so many interesting titles!  Here are just a few, with links to OBIS for the full catalog record:

In our own image: savior or destroyer? The history and future of artificial intelligence.  OBIS

The new cosmos : answering astronomy's big questions.  OBIS

Hydrogen-bonded capsules : molecular behavior in small spaces.  OBIS

A world from dust : how the periodic table shaped life.  OBIS

Water as a social opportunity.  OBIS

Creating Africas : struggles over nature, conservation and land.  OBIS

Evolutionary medicine.  OBIS

The human advantage : a new understanding of how our brain became remarkable.  OBIS

Enjoy your summer reading!

Summer Reading - inside or out?

Whether you prefer the sunny tables on the Science Center piazza or the cool comfort of the science library, the time for summer reading has arrived.  Browse the new books at our front window, where views to the north and south are seen simultaneously.  So many to consider:

Take a road trip with a Roadside Geology... guide book;
Tackle history of science with books on Kepler, the Royal Society, and Aristotle;
Learn what inspired Audubon and F. W. Taylor;
Enjoy little know facts about Melon and Fats;
Consider possibilities for REDD to mitigate climate change.

See you soon!

Summer road trip? Take along a roadside geology guide.

Three new Roadside Geology books arrived in this week's new book shipment:

• Roadside geology of Colorado
• Roadside geology of Oregon
• Roadside geology of Utah

 joining the 30 or so books for other states in our collection.  These books are a great way to learn more about the physical environment you may be speeding through, and are a good excuse to stop and appreciate the locale - to enjoy the journey as much as the destination.

While you're considering landforms and formations, you could also identify birds, mammals, reptiles, snakes, invertebrates...  the library is brimming with helpful guides, both regional and world-wide in focus, to animals in various ecosystems.  Plants, too, for that matter!  Any currently enrolled student (as well as faculty and staff) who will be returning in the fall is welcome to borrow books over the summer.  Just ask!

Earth Day interview with Lab Girl author Hope Jahren

Catalog record in OBIS

NPR Morning Edition's Renee Montagne spoke this morning with geobiologist Hope Jahren about her book Lab Girl (now in new book processing, heading to the science library).  Jahren spoke eloquently about her experience of being the only female in her field (and lab) and the challenges that presented, as well as her commitment to guiding young women through similar challenges with more support and encouragement than she received.  As a scientist who studies plants, seeds and soil, she also expressed beautifully the role of trees in ecosystems, and implored listeners to plant a tree and "choose wisely."  A tree becomes a companion through life, doing so much for all forms of life in its environs.  To paraphrase, Jahren concluded by stressing, "I'm not saying, 'save the trees;' rather, that trees can save us."  Listen.

Jahren's words are a reminder to continue nurturing the tiny lilac tree I planted last year around Earth Day.  I'm happy to see it is sprouting new leaves this spring, sheltered on the south side of the house.

Love Your Library During National Library Week

http://tinyurl.com/ALAbutton

Tell us what you love about the science library!  Spread a little cheer during National Library Week.  Look for the blue entry box at the circulation desk (under the hanging air plant). We'll read all of the entries on April 17 and post some of them here.   UPDATE: see the comment from Alison.

Top ten things we love about our library users:

9. Seeing you work together in group study rooms.
8. Knowing you're comfortable enough to nap at the window seats.
7. Cleaning up after yourself (gold stars for you!).
6. Remembering to take your print job with you.
5. Returning library materials on time ;-) -- so nice.
4. Leaving the cutting blade down when you're finished with the cutting board (that thing looks lethal).
3. Watching you help a friend figure out the scanning procedure.
2. Handing your ID to us with a friendly smile when borrowing items. 

And the absolute best thing:
1. Asking interesting questions about fascinating subjects.  That makes our day.

So ask away! Love your library all year long, and share the joy during National Library Week.

Suing the Federal Government and Fossil Fuel Industry on Behalf of Future Generations

From Our Children's Trust:

April 8, 2016:  Today, U.S. Magistrate Judge Thomas Coffin of the federal District Court in Eugene, OR, decided in favor of 21 young Plaintiffs, and Dr. James Hansen on behalf of future generations, in their landmark constitutional climate change case brought against the federal government and the fossil fuel industry. The Court’s ruling is a major victory for the 21 youth Plaintiffs, ages 8-19, from across the U.S. in what Bill McKibben and Naomi Klein call the “most important lawsuit on the planet right now.”

OBIS record

The decision by Judge Coffin coincided, incidentally, with the final day of Oberlin's first Global Issues Symposium: Climate Change Consequences, possibly as we were in the midst of discussion on "Connecting the Global and Local: Assessing the Future of Climate Resilient Action."

It is an interesting coincidence, given our focus on climate change consequences for indigenous peoples and Judge Coffin's words regarding those consequences on young people: ..."the intractability of the debates before Congress and state legislatures and the alleged valuing of short term economic interest despite the cost to human life, necessitates a need for the courts to evaluate the constitutional parameters of the action or inaction taken by the government. This is especially true when such harms have an alleged disparate impact on a discrete class of society." [page 8 of the ruling]

Eudicot phylogenetics: new publication from Mike Moore

Sun Y; Moore Michael J, Associate Professor of Biology; Zhang S; Soltis PS; Soltis DE; Zhao T; Meng A; Li X; Li J; Wang H. 2016. Phylogenomic and structural analyses of 18 complete plastomes across nearly all families of early-diverging eudicots, including an angiosperm-wide analysis of IR gene content evolution. Molecular Phylogenetics and Evolution 96:93-101

http://tinyurl.com/ISSN1055-7903

Partial abstract:  The grade of early-diverging eudicots includes five major lineages: Ranunculales, Trochodendrales, Buxales, Proteales and Sabiaceae. To examine the evolution of plastome structure in early-diverging eudicots, we determined the complete plastome sequences of eight previously unsequenced early-diverging eudicot taxa… and compared them to previously published plastomes of the early-diverging eudicots… Maximum likelihood phylogenetic analysis of a 79-gene, 97-taxon data set that included all available early-diverging eudicots and representative sampling of remaining angiosperm diversity largely agreed with previous estimates of early-diverging eudicot relationships.

Best Book Return of the Day: Body by Darwin

Science library: QH366.2 .T374 2015

We are frequently distracted by books just returned by a library borrower.  Today it was Body by Darwin that caught my attention - how evolution shapes our health and transforms medicine. Author Jeremy Taylor states, "I do try to describe the deep evolutionary background to some human medical conditions and to explain why they exist in the first place... [to] leave readers with a new respect for evolution as the prime mover for the structure and function of human bodies, even if it does, on occasion, cause them to break down and drive us into the ER!"

It is fascinating reading for Spring Break - from barefoot running (don't try this without understanding the importance of pace and posture) to neuroimmune responses that contribute to developing Alzheimer's, and the multiple, negative impacts of depleting "old friends" microbiota in the human body, better understanding of human evolution is giving remarkable insights into the cause, prevention and treatment of ailments.   Check it out!

Itchin' for Spring Break? Get Into the Swing of It.

If your spring break plans include a bit of golf, consider taking this book with you:

The science of the perfect swing / Peter Dewhurst.  Now on the new book shelf.

Does spring bring thoughts of baseball opening day?  You might like to know something about that science of that sport:

Physics of baseball & softball / Rod Cross
online at Springer books, access through OBIS.

Wherever you're going, here's hoping that you'll have time for relaxation and renewal.  There are some delightful titles on the new book shelf that can entertain and enlighten you through the week ahead.  Skunk, for example.  Goodness knows they are becoming more active this time of year.  Find out why in this book from the Reaktion Animal series.

Crystal structure, pulsar timing: new publications from faculty and alumni

Lai, Holden W. H. '15, Ren A. Wisconsin '15, Cassandra A. Zentner '13, M. Zeller, and Jesse L. C. Rowsell ✝ 2016. Supramolecular Assembly of Tris(4-carboxyphenyl)arenes: Relationship between Molecular Structure and Solid-State Catenation Motifs. Crystal Growth & Design 16:821-833.

abbreviated abstract:
The crystal structures of seven 1,3,5-tris(4-carboxyphenyl)arenes with functionalized central arene rings are reported... To better understand and appreciate these complicated crystal structures, they were categorized into four distinct stacking/catenation families: simple stacking, single-layer offset catenation, double-layer offset catenation, and rotated-layer catenation. The unique structure of the unfunctionalized parent compound 1,3,5-tris(4-carboxyphenyl)benzene is rationalized in light of the structural behavior of its derivatives.   ✝ deceased

abbreviated abstract:
The dispersion measure (DM), the column density of free electrons to a pulsar, is shown to be frequency dependent because of multipath scattering from small-scale electron-density fluctuations. DMs vary between propagation paths whose transverse extent varies strongly with frequency, yielding arrival times that deviate from the highfrequency scaling ... We discuss implications for methodologies that use large frequency separations or wide bandwidth receivers for timing measurements. Chromatic DMs are partially mitigable by including an additional chromatic term in arrival time models. Without mitigation, an additional term in the noise model for pulsar timing is implied. In combination with measurement errors from radiometer noise, an arbitrarily large increase in total frequency range (or bandwidth) will yield diminishing benefits and may be detrimental to overall timing precision.

Proteins and Enzymes: New publications from Biology faculty Maureen Peters and Aaron Goldman

As found in Web of Science, Oberlin authors in bold font:

10.1152/ajpcell.00111.2015

Allman, Erik, Qian Wang, Rachel L. Walker, Molly Austen, Maureen A. Peters, Associate Professor of Biology, and Keith Nehrke. 2016. Calcineurin homologous proteins regulate the membrane localization and activity of sodium/proton exchangers in C. elegans. American Journal of Physiology-Cell Physiology 310 (3) (FEB 1): C233-42.  Access at publisher's website.

Partial abstract: “[W]e have used [C. elegans] to interrogate PBO-1's mechanism of action. Using fluorescent tags to monitor Na+/H+ exchanger trafficking and localization, we found that loss of either PBO-1 binding or activity caused NHX-7 to accumulate in late endosomes/lysosomes. [These and other results lead us to] conclude that the role of CHP in Na+/H+ exchanger regulation differs between apical and basolateral transporters. This further emphasizes the importance of proper targeting of Na+/H+ exchangers and the critical role of CHP family proteins in this process.”

Goldman, Aaron David, Assistant Professor of Biology, Joshua T. Beatty '15, and Laura F. Landweber. 2016. The TIM barrel architecture facilitated the early evolution of protein-mediated metabolism. Journal of Molecular Evolution 82 (1) (JAN): 17-26.  Access in OhioLINK Electronic Journal Center.

Partial abstract: "We show that [triosephosphate isomerase (TIM) barrel] enzymes corresponding to the most taxonomically broad superfamilies also have the broadest range of functions, often aided by metal and nucleotide-derived cofactors that are thought to reflect an earlier stage of metabolic evolution. By comparison to other putatively ancient protein architectures, we find that the functional diversity of TIM barrel proteins cannot be explained simply by their antiquity. Instead, the breadth of TIM barrel functions can be explained, in part, by the incorporation of a broad range of cofactors, a trend that does not appear to be shared by proteins in general. These results support the hypothesis that the simple and functionally general TIM barrel architecture may have arisen early in the evolution of protein biosynthesis and provided an ideal scaffold to facilitate the metabolic transition from ribozymes, peptides, and geochemical catalysts to modern protein enzymes."

Robert Owen contributes to significant findings by LIGO on gravitational waves

The exciting announcement of confirmation from the research collaborative LIGO of gravitational waves from colliding black holes has been picked up by a number of media outlets, including NPR  and Inside Science.  Robert Owen, Assistant Professor of Physics, is one of many collaborators who contribute to LIGO.  He “has for many years done calculations, animations, and theoretical work in support of this discovery,” observed colleague Dan Stinebring, Francis D. Federighi Professor of Physics and Astronomy.  Sinebring also observes gravitational waves, detecting these phenomena from supermassive black holes.  He collaborates as a contributor on the NANOGrav research project.  This is a remarkable achievement, and we are thrilled to recognize both Owen and Stinebring for their contributions to astrophysics.

New faculty publications: Hormones in Alzheimer's; Students as Change Agents

Two new publications from faculty, alumna and staff, as indexed in Web of Science:

Burnham, Veronica L '14., and Janice E. Thornton (Professor or Neuroscience) 2015. Luteinizing hormone as a key player in the cognitive decline of Alzheimer's disease. Hormones and Behavior 76:48-56.  [full text from sciencedirect.com]

Partial abstract: "Luteinizing hormone, which is increased with age in both men and women (in response to removal of negative feedback), has surfaced as a potentially powerful player in the risk and onset of Alzheimer's disease. Mounting evidence in basic research and epidemiological studies supports the role of elevated luteinizing hormone in exacerbating age-related cognitive decline in both males and females. This review summarizes the recent developments involving luteinizing hormone in increasing the cognitive deficits and molecular pathology characteristic of Alzheimer's disease."

Daneri, Daniel Rosenberg (A. J. Lewis Assistant Project Manager), G. Trencher, and John Petersen (Professor of Environmental Studies). 2015. Students as change agents in a town-wide sustainability transformation: the Oberlin Project at Oberlin College. Current Opinion in Environmental Sustainability 16:14-21.  [full text from sciencedirect.com]

Partial abstract:  "The potential of multi-stakeholder partnerships to enrich sustainability education through experiential learning is well documented. Yet there is less knowledge about the impacts on partnerships that result from student participation and the models that facilitate students to serve as agents of change and research. To address this knowledge gap, we examine the Oberlin Project at Oberlin College, an ambitious community partnership aimed at town-wide climate neutrality and sustainability. Findings show that contributions to stakeholder learning and partnership progress can occur through student participation models such as project-based learning, transacademic research, and internships."

10 Top Retractions of 2015, from Retraction Watch

Peer-review and fine editorial process do not guarantee scientific integrity and valid research results, sadly enough.  As reported in The Scientist, Retraction Watch has published its Top 10 Retractions of 2015 and the list includes published articles from such high profile titles as Science, Cell, Cancer Research, and Genes and Development.  Errors in judgment, neglecting essential statistical tests, falsifying data, plagiarism, and faulty study design were all reported.   Critical evaluation by all reviewers, editors and readers is still needed, even for high profile researchers with distinguished careers and piles of papers to their credit.  Fraudulent research can lead to legal action, a prison sentence and a judicial decision that grant funding must be repaid. Oh my.

Antiparasite Drug Developers Win Nobel Prize

News of today's Nobel Prize announcement can be found in countless ways.  This is the highly readable account from The Scientist: "William Campbell, Satoshi Omura, and Youyou Tu have won this year’s Nobel Prize in Physiology or Medicine in recognition of their contributions to antiparasitic drug development."

...or listen to Rob Stein's report on  NPR Morning Edition.  Nobel Prize week is always inspiring, and this year's winners for Medicine are no exception.  Their research has led to treatment of potential benefit to the nearly 4 billion people worldwide who are exposed to these particular disease-causing parasites.

Climate Science, 50 Years Later

From the American Association for the Advancement of Science:

On 5 November, 1965, the group now known as the President’s Council of Advisors on Science and Technology (PCAST) cautioned President Lyndon B. Johnson that continued accumulation of atmospheric carbon dioxide resulting from fossil-fuel burning would “almost certainly cause significant changes” and “could be deleterious from the point of view of human beings.”

AAAS observes that fifty years later, "the reality of human-caused climate change has been reaffirmed by virtually every leading scientific organization as well as the vast majority of individual climate scientists worldwide."  The public is invited to participate in a free day-long scientific symposium to commemorate the 50th Anniversary of the First Official Climate-Change Warning to a U.S. President, to "review what scientific research has revealed over the past 50 years, and offer a forward-looking assessment of the range of scientific, technological, communication, and policy options for the future."  Registration is required.  More @ AAAS.

Review article by Gunnar Kwakye, et al., on manganese and Parkinson's disease.

New publication by Neuroscience Assistant Professor G. Kwakye, indexed by Web of Science:

 

Manganese-Induced Parkinsonism and Parkinson's Disease: Shared and Distinguishable Features.
Kwakye, Gunnar F.; Paoliello, Monica M. B.; Mukhopadhyay, Somshuvra; Bowman, Aaron B.; Aschner, Michael

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH, 12 (7):7519-7540; 10.3390/ijerph120707519 JUL 2015.  Open access article at PubMed Central.

Partial abstract:

[This] review discusses the advances made in understanding the essentiality and neurotoxicity of Manganese (Mn). We review occupational Mn-induced parkinsonism and the dynamic modes of Mn transport in biological systems, as well as the detection and pharmacokinetic modeling of Mn trafficking. In addition, we review some of the shared similarities, pathologic and clinical distinctions between Mn-induced parkinsonism and Parkinson's disease. Where possible, we review the influence of Mn toxicity on dopamine, gamma aminobutyric acid (GABA), and glutamate neurotransmitter levels and function. We conclude with a survey of the preventive and treatment strategies for manganism and idiopathic Parkinson's disease.

Oberlin students ready to save the world: a Sierra Magazine eco-valedictorian

Cover art by Nate Williams

Oberlin ranked 5 out of the "10 coolest schools" in the United States, on the Sierra Club "green" scale, including measures of sustainability, eco-centered curriculum, energy and water usage, sources of energy and an overall culture of conservation.  Oberlin's score was 769.50, just slightly ahead of University of Connecticut and trailing a bit behind Colorado State University with its School of Global Enviornmental Sustainability.  Univesity of California, Irvine was the leader and a two-time winner, with a score of 859.75.  See the full lists and rankings @ sierra club.org/coolschools.  The story is in the September/October 2015 print issue, received by donation in the science library from Sierra Club life member Alison Ricker.

Three New Publications from the Chemistry Department

Robert Q. Thompson.
Homocapsaicin: It's NOT the 7-ene-9-methyl isomer.
Food Chemistry 2015, 182, 72-73.
There are key differences in the occurrence of homocapsaicin isomers: 6-ene-8-Me (more abundant in nature), 6-ene-9-Me (less abundant in nature), and 7-ene-9-Me (not found in nature). Nevertheless, even in scientific journals, the 7-ene-9-Me isomer has been erroneously associated with natural sources on numerous occasions.

Crystal structure of 2,3-dimethylmaleic anhydride: continuous chains of electrostatic attraction.
Acta Crystallographica, Sect. E: Crystallographic Communications 2015, 71, 950-955
In the crystal structure of 2,3-dimethylmaleic anhydride, C6H6O3, the closest non-bonding intermolecular distances, between the carbonyl C and O atoms of neighboring molecules, were measured [and found to be surprisingly close]. Computational modeling suggests that this close contact is caused by strong electrostatic interactions between the carbonyl C and O atoms.  Open Access.

Liora E. Mael, Michael I. Jacobs, and Matthew J. Elrod.
Organosulfate and Nitrate Formation and Reactivity from Epoxides Derived from 2-Methyl-3-buten-2-ol.
Journal of Physical Chemistry A 2015, 119, 4464-4472
Recent work has suggested that 2-methyl-3-butene-2-ol (MBO)-derived epoxide intermediates are responsible for some of the molecular species commonly found in ambient secondary organic aerosol (SOA). Nuclear magnetic resonance techniques were used to study the reaction kinetics and products of two potential MBO-derived epoxides under acidic solution conditions in the presence of sulfate and nitrate nucleophiles… the nucleophilic reactions were observed to be quite regiospecific, and the tertiary addition product species were found to hydrolyze on atmospherically relevant time scales.

Rats on a gambling task tell us something about decision making in schizophrenia

A new publication by Assistant Professor of Neuroscience Tracie Paine:

Paine TA, O'Hara A, Plaut B, Lowes DC. 2015. Effects of disrupting medial prefrontal cortex GABA transmission on decision-making in a rodent gambling task. Psychopharmacology (Berl ) 232(10):1755-65

Partial abstract:  "Decision-making is a complex cognitive process that is mediated, in part, by subregions of the medial prefrontal cortex (PFC). Decision-making is impaired in a number of psychiatric conditions including schizophrenia. Notably, people with schizophrenia exhibit reductions in GABA function in the same PFC areas that are implicated in decision-making… [The data collected in this experimental study of rat cognitive function] provide proof-of-concept evidence that disruptions in GABA transmission can contribute to the decision-making deficits in schizophrenia."
