"Science Helps Squeeze Out Every Last Drop" - from Inside Science

Inspired by the lotus leaf.  Who would have thought?
 I have bottles standing upside down at my sink at this moment... 

(from Inside Science) -- "Sometimes science solves longstanding mysteries like gravitational waves, or finds one of the fundamental building blocks of the universe called top quarks.

"Or sometimes science just helps with some of life’s little frustrations -- like getting the last drop of shampoo out of the bottle. There’s just no getting around it -- no matter how much you squeeze or shake a shampoo bottle -- there’s always going to be some left behind.

"Now scientists have invented a coating for the inside of bottles, so getting every last drop out is finally achievable.

"The lotus leaf's bumpy surface, which lets liquids roll right off, led the researchers to create a coating for the inside of bottles made of tiny nanoparticles. If you could look at the coating under a microscope, you would see a tiny "y” that cradles droplets of shampoo, which are balanced on top of a tiny bubble of air. This minimizes the contact between the shampoo and the inside of the shampoo bottle.

"The video shows shampoo and laundry detergent sticking to an uncoated surface and then as shampoo and detergent slide off a surface treated with the new coating. 'We can create a structure which will repel liquid but we’d like to make sure it does it for a long period of time,' said Bhushan. Once the coating is perfected it will be several years before we can buy products that use the coating in their bottles. So, until then, keep storing bottles upside down or give them a good shake."

"Forensic chemistry and its flip side"

New publication from Robert Thompson, Professor of Chemistry:

Thompson, Robert Q. Forensic Chemistry and Its Flip Side. Journal of Chemical Education 2016, 93, 1677-1678.
Forensic chemistry is the focus of this year's National Chemistry Week and a strengthening and growing discipline of research and teaching. Forensic science deals mainly with the aftermath of crime. The flip side is the science of eliminating or ameliorating violent acts before they happen. In our laboratories and classrooms, are there ways to address the targeted violence and terrorism that fill the news cycle and generate fear in us and our students? While we have conversations on our individual campuses, a conversation among us chemistry educators on a regional or national scale would be even more helpful. Copyright © 2016 The American Chemical Society and Division of Chemical Education, Inc.

Eleven alumni scientists: 2,416 articles cited 132,211 times by others

A recent symposium in the Science Center prompted a bit of citation analysis using the Web of Science. The eleven National Academy of Sciences members and OC alumni who presented during the three concurrent sessions have published a total of 2,416 articles, which have been cited by other articles 132,211 times (not including self-citations).

OC class years for these alumni range from 1954 to 1977.

This seems a good case in point on the impact of a liberal arts education for advancing scientific research and knowledge.

Three of the most highly cited papers from these researchers were published in Nature titles, two were published in Cell and two were published in Science.

The other papers appeared in:
Annual Review of Biochemistry
Journal of Neurophysiology 
Psychological Review, and
Transactions of the American Mathematical Society.

Complete citations are shown in the next image.  A Word document version of the list is shared in Google drive.

Citation reports in Web of Science are quickly compiled from a list of search results for any author - making certain of the correct form of the author's name and refining search results by broad subject categories helps produce a fairly accurate report of a researcher's publishing record.  Just click on Create Citation Report when you are confident that the search results adequately represent the publications from one author (see the screen shot, below, of the top right corner of a search results page).

We Love Open Access; featuring A.D. Goldman in PLoS Genetics

The open lock symbol that represents Open Access
What do we mean by Open Access?  I'm so glad you asked this very timely question, during Open Access Week, Oct. 24-30, 2016.

Get the sense of Open Access immediately at Public Library of Science:, "a nonprofit publisher, innovator and advocacy organization."  It's an exciting place.
"Top scientists from more than 190 countries around the world have published with PLoS.  Among them, 59 Nobel Laureates.

"160,000+ peer-reviewed articles are free to access, reuse and redistribute.
Anytime, Anywhere."
Input "Oberlin College" in the PLoS Search box and get 133 results, including this recent paper from Assistant Professor of Biology Aaron Goldman:

Goldman, Aaron David and Laura F. Landweber. "What is a Genome?" PLoS Genetics 12, no. 7 (2016): e1006181.

Here's the really cool part about open access: rather than assigning copyright to the publisher, the authors retain copyright to their created work and grant free use of the material, without a barrier imposed by a subscription fee. This is an amazing transformation in the use of scholarly materials, which had for generations been accessible only to researchers affiliated with libraries who were able to pay the journal subscription. Open access materials are frequently published under the very generous Creative Commons Attribution License.

In the case of Goldman's paper: "Copyright: © 2016 Goldman, Landweber. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited."

Thanks for publishing with PLoS, Professor Goldman!

What do the authors conclude about the definition of a genome?  Since it is an open access article, I can copy that conclusion here: ... "the genome as an informational entity, often but not always manifest as DNA, encoding a broad set of functional possibilities that, together with other sources of information, produce and maintain the organism."  Read the whole article.

Looking forward to hearing Robert Krulwich on November 5

Robert Krulwich '69, co-host of Radiolab, will be the featured speaker at the Friends of the Library annual dinner on Saturday, November 5.  It is sure to be both informative and entertaining!  The talk is open to the public - arrive shortly before 8pm in the Root Room, Carnegie Building, to grab an open seat.

An example of Krulwich's ability to explain a complex and vexing topic in terms that are clearly understood is the collaboration of NPR and Odd Todd animations to create the five episodes of "Global Warming: It's All About Carbon."  Who knew that a carbon atom could have such a charming persona?  Albeit sobering in the context of too much atmospheric carbon - released through decades of use of fossil fuels - creating the greenhouse effect encircling the globe.

A keyword search in OBIS on carbon and climate yields over 1000 titles; possibly none of them are as pithy and helpful for someone new to the topic as Krulwich's videos created with Odd Todd.  Do come back to the library for in-depth understanding of climate disruption: search climatic changes or climate change mitigation for best results.  Climate change: a very short introduction is an excellent first choice, or, for a fuller review of carbon, check out Carbon age : how life's core element has become civilization's greatest threat.

DNA + Light: Talk by Carlos E. Crespo-Hernández

Talk sponsored by the Department of Chemistry and Biochemistry 
Thursday, September 22, 2016
4:45pm  Science Center A255

DNA + Light: From Nucleic Acid Bases to Modifications that Enable Damage to Carcinoma Cells

Carlos E. Crespo-Hernández, Department of Chemistry and Center for Chemical Dynamics, Case Western Reserve University, Cleveland, OH, United States.

Partial abstract: Photodynamic therapy (PDT) is an effective treatment option for a variety of skin cancers and diseases. Recently, the DNA analog 4‑thiothymidine (4tT) has demonstrated efficacy as a PDT agent against rapidly-dividing malignant cells while leaving normal cells unharmed. Its phototoxic activity and low off-target effects make this thiobase a highly promising PDT candidate. However, the depth of tissues able to be treated with 4tT is limited by its absorption cutoff at ~365 nm. A thiobase photosensitizer able to absorb longer wavelengths of light is needed because longer wavelengths are able to reach more invasive skin cancers and diseases. Recently, we found that doubling the sulfur substitution of the nucleobase increases its photoreactivity and simultaneously shifts its absorption spectrum into the near-visible region (~395 nm) where light can penetrate more than 100% deeper into tissues. In vitro screening experiments performed in our laboratory using epidermoid carcinoma cells (A431) have revealed several doubly-substituted thiobase derivatives that are effective photosensitizes.

Citizen Science Projects Celebrate National Park Service Centennial

Five National Park Citizen Science Projects Anyone Can Join: Celebrate the NPS centennial by lending a hand. -- Sierra Club

It's unlikely that anyone on campus will be participating in NPS citizen science projects on the actual centennial date, August 25 - we will be in the midst of new student orientation that day.  But the opportunities for citizen science projects throughout the year are numerous and varied.  Check it out!

Citizen science projects are ongoing worldwide, investigating many different subjects under a whole host of sponsors; see Discover magazine's Top Ten citizen science projects of 2015 for a hint at the diversity of options.  Find more at SciStarter.

Back to the National Park Service centennial - you can visit a lovely National Park within a one hour drive of Oberlin.  It doesn't have the awesome peaks of Glacier or the wildlife of Yellowstone or wild ocean shores of Acadia, but it offers excellent hiking trails and hundreds of acres of beautiful Ohio forest, fields, meadows, wetlands and streams.  Plus the old Ohio-Erie canal towpath for biking and Blossom Music Center, summer home of the Cleveland Orchestra.  Visit the Cuyahoga Valley National Park in every season to appreciate all there it has.

What is a genome? - a review from Aaron Goldman

Just published in the open access journal PLOS Genetics, with 3816 views in its first week on the site (open access truly does have a far reach!):

Goldman, Aaron David, Assistant Professor of Biology, and Laura F. Landweber. 2016. "What is a Genome?" PLOS Genetics 12 (7): e1006181.

Partial Abstract:
The genome is often described as the information repository of an organism... Several emerging areas of research demonstrate that this definition is an oversimplification. Here, we explore ways in which a deeper understanding of genomic diversity and cell physiology is challenging the concepts of physical permanence attached to the genome as well as its role as the sole information source for an organism.

Genotype-environment interactions in Arabidopsis thaliana - new publication from A. Roles

Roles, Angela J., Assistant Professor of Biology; Rutter, M.T., Dworkin, I., Fenster, C.B., and Conner, J.K. (2016). Field measurements of genotype by environment interaction for fitness caused by spontaneous mutations in Arabidopsis thaliana. Evolution 70, 1039-1050.

Journal banner @ Wiley Online
Partial abstract: As the ultimate source of genetic diversity, spontaneous mutation is critical to the evolutionary process. The fitness effects of spontaneous mutations are almost always studied under controlled laboratory conditions rather than under the evolutionarily relevant conditions of the field. We studied the fitness effects of 25 generations of accumulated spontaneous mutations in Arabidopsis thaliana in two geographically widely separated field environments, in Michigan and Virginia. We observed genotype-environment interactions in the fitness effects of new mutations, such that the effects of mutations in Michigan were a poor predictor of their effects in Virginia and vice versa. In particular, mutational variance for fitness was much larger in Virginia compared to Michigan. This strong genotype-environment interaction would increase the amount of genetic variation maintained by mutation-selection balance.

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.

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.

Fascinating stuff on the new book shelf

What's on the new book shelf?
murder, skeletons, misinformation
spectroscopy, nerves, sexual selection
geophysics, genome, Jurassic plate rotation...
and so much more.

It never fails - a shipment of fantastic reading arrives just at the point in the semester when everyone is thoroughly engaged in required reading for courses and papers or stretched to the limit by rehearsals, performances, lectures and athletics.  April is so full of life, challenge and opportunity - come see your opportunities for yet more wonderful reading, just added to the new book shelf.
