150th Anniversary Today! Darwin's On the Origin of Species

It has been a year of celebration and remembrance of Charles Darwin (born 200 years ago last February 12) and his pivotal work, On the origin of species by means of natural selection... but this is THE day! November 24, 1859, marked the beginning of a great new direction in the understanding of natural history, despite resistance to the implications for human origins that continues today.

The library's copy of an early edition is in Special Collections, but there many facsimiles and later editions to browse in the science library, including volumes 15 and 16 of Charles Darwin's Works.

On our new book shelf is one of the many books purchased this year that relate to Darwin directly or evolution more generally: The Origin then and now: an interpretive guide to the Origin of Species. Author David Reznick's begins his preface with: "Darwin's Origin of Species has been described as one of the books that is most widely referred to, but least likely to be read." You can buck that trend and read at least a bit of Origin at the Darwin Online site, or peruse the Darwin Correspondence project to commemorate the day, and enjoy letters between Darwin and his publisher John Murray.

Deconstructing Global Warming: Richard Lindzen on Campus

If you are unaware of MIT Professor Richard Lindzen's role in the community of climate change skeptics, this New York Times story [March 8, 2009] on the 2009 International Conference on Climate Change is a good introduction. Skeptics Dispute Climate Worries and Each Other, by Andrew Revkin, included these paragraphs:
  • In a keynote talk Sunday night, Richard S. Lindzen, a professor at M.I.T. and a longtime skeptic of the mainstream consensus that global warming poses a danger, first delivered a biting attack on what he called the “climate alarm movement.”
  • There is no solid scientific evidence to back up the models used by climate scientists who warn of dire consequences if warming continues, he said. But Dr. Lindzen also criticized widely publicized assertions by other skeptics that variations in the sun were driving temperature changes in recent decades. To attribute short-term variation in temperatures to a single cause, whether human-generated gases or something else, is erroneous, he said.
  • But several climate scientists who are seeking to curb greenhouse gases strongly criticized the meeting. Stephen H. Schneider, a climatologist at Stanford University and an author of many reports by the intergovernmental climate panel, said, after reviewing the text of presentations for the Heartland meeting, that they were efforts to “bamboozle the innocent.”
The Third International Conference on Climate Change sponsored by the Heartland Institute, took place June 2, 2009, in Washington, D.C., with the stated purpose "to expose Congressional staff and journalists to leading scientists and economists in the nation’s capital." Proceedings of that conference online include Professor Lindzen's keynote address (with options for PowerPoint, pdf, audio, and video).

Was T-Rex Hot Blooded? PLoS ONE News

PLoS ONE published this article online on November 11, 2009:

Pontzer H, Allen V, Hutchinson JR, 2009 Biomechanics of Running Indicates Endothermy in Bipedal Dinosaurs. PLoS ONE 4(11): e7783. doi:10.1371/journal.pone.0007783

It has been viewed nearly 1900 times in two days, and downloaded 450 times as of this moment. Open access has obviously benefited a great number of readers interested in this topic!

Here's a bit from the authors' methodology and results summary:

"Here we describe two new biomechanical approaches for reconstructing the metabolic rate of 14 extinct bipedal dinosauriforms during walking and running. These methods, well validated for extant animals, indicate that during walking and slow running the metabolic rate of at least the larger extinct dinosaurs exceeded the maximum aerobic capabilities of modern ectotherms, falling instead within the range of modern birds and mammals... Our results support the hypothesis that endothermy was widespread in at least larger non-avian dinosaurs. It was plausibly ancestral for all dinosauriforms (perhaps Ornithodira), but this is perhaps more strongly indicated by high growth rates than by locomotor costs."

Read Peter Ward's Out of Thin Air for a helpful review (as of 2006) of the evolution of endothermy, and access a very brief discussion of dinosaur endothermy written for the general public at the University of California Museum of Paleontology DinoBuzz.

Writing Study Ties Autism To Motor-Skill Problems

NPR Morning Edition aired this story by Jon Hamilton this morning, observing that severe problems with handwriting is "indicative of a much larger problem with motor skills." Amy Bastian, a neuroscientist who directs the Motion Analysis Laboratory at Kennedy Krieger Institute in Baltimore, found that many children with some degree of autism "have trouble holding a fork, buttoning a shirt, or tying their shoelaces."

"And these problems with motor skills may carry over into social interactions," Bastian says. "These are the kids that are going to get picked last for kickball... who are clumsy, who already have difficulty relating to other kids. And the motor component probably makes things worse."

From Jon Hamilton's story: Bastian says a lack of motor skills can also make it harder to communicate through subtle gestures and facial expressions. And people who can't make these gestures and expressions themselves often have trouble understanding what they mean when other people use them. The inability to read faces and gestures is a hallmark of autism.

The research findings were published in yesterday's edition of Neurology. Read the authors' abstract at the publisher's web site:
Christina T. Fuentes, Stewart H. Mostofsky, and Amy J. Bastian
Children with autism show specific handwriting impairments.
Neurology 2009 73: 1532-1537.

Chemistry's Turn to Shine: Year of Science Theme for November

The Periodic Table is featured prominently on the Year of Science web site this month, to kick off November's celebration of chemistry. For what is life without chemistry? Not life, that's for certain. As just about any introductory chemistry text will tell you, the six most abundant elements in living systems are oxygen, carbon, hydrogen, nitrogen, phosphorus and sulfur. How can just 6 elements do so much of the work in the human body? Ah, that's part of the fascination of molecular science. [Encyclopedia Britannica overview]

Interdisciplinary research at the molecular level has led to the creation of a great number of specialized journals, many of which can be found in the OhioLINK Electronic Journal Center by browsing Molecular... or Journal of molecular... as the first part of journal titles. Browse other chemistry related journals in OhioLINK EJC.

Whether you sailed through p-chem with flying colors and completely understand the relationship between Gibbs free energy and entropy, or barely made it through high school chemistry and have forgotten the difference between moles and grams, you can have fun with chemistry. Have fun with science in the lab of Dr. Shakahsiri.

Ohio Voters! Be Informed on Issue 2

in brief: This Chicken Urges Ohio to Vote NO on Issue 2 [George Jones Farm video]

Issue 2 on the Ohio state ballot would amend our state constitution to create a Livestock Care Standards Board, with very specific language regarding the appointment, membership and oversight responsibilities of the board. The proposal came about, in part, to forestall a ballot initiative from the Humane Society of the United States, which would have given voters the ability to consider issues such as the size of cages for egg-laying chickens and standards for "gestation confinement crates" for pregnant sows on large pig farms. The League of Women Voters of Ohio and Ohio Supreme Court Justice Maureen O’Connor agree that Issue 2 is inappropriate for the constitution, inserting language that is too specific for such a pivotal document, which should be a broad, clear statement of principles. The amendment attempts to control agriculture in a manner more appropriate for legislative action.

Other groups opposing this constitutional amendment include:

First US Book on Psychiatry Published 197 Years Ago

On this date in 1812, Medical inquiries and observations upon the diseases of the mind, by Benjamin Rush, M.D., was copyrighted. Published by Kimber and Richardson of Philadelphia, it was the first U.S. book on psychiatry. Oberlin College Library owns three editions in print, all shelved in Special Collections. We also link to digital versions of the book from records in OBIS [1812 digital version].

Works of Benjamin Rush are covered in a guide from Greenwood Press: Benjamin Rush, M.D. : a bibliographic guide / compiled by Claire G. Fox, Gordon L. Miller, and Jacquelyn C. Miller.

This tidbit of publishing history was taken from The Illustrated almanac of science, technology, and invention: day by day; facts, figures, and the fanciful / Raymond L. Francis. Shelved behind our reference desk [OBIS record], it is great fun to browse through. Also on this date in history the Erie Canal opened in upstate New York, connecting the Hudson River with Lake Erie; the washing machine was patented; and the mule first arrived in the United States (shipped from King Charles III of Spain to George Washington).

PubMed Central Combines Free Access and Open Access

From a user's perspective, it's difficult to focus on the difference between open access and free access to a journal article -- especially if all one intends to do is read the paper for an assignment in an undergraduate course. The distinction is important. PubMed Central is primarily an archive providing free access to traditionally copyrighted works, with the accompanying restrictions on reuse. It is a fantastic resource, providing access to the complete digital archive for nearly 800 journals, excluding some portion of the current issues for many titles. In addition, PMC has the author manuscripts of articles published by NIH-funded researchers in various non-PMC journals.

A smaller number of journals are part of the Open Access subset, and are protected under Creative Commons license. The open access journals are easy to spot in the PMC list of titles, just look for the OA icon.

A relatively new OA journal in the PMC list is Beilstein Journal of Organic Chemistry, indicative of the broader range of subjects in the PMC archive than might be expected. The Beilstein Journal publishes reviews, preliminary communications and full research articles in all areas of organic chemistry.

Oberlin Group Authors in Open Access Journals at BioMedCentral

BioMedCentral (BMC) publishes 204 peer-reviewed open access journals; all of the research articles in those journals are "immediately and permanently available online without charge. A number of journals require an institutional or a personal subscription to view other content, such as reviews or paper reports." The Oberlin Group libraries have a consortial agreement with BMC, granting research staff and students from those institutions a 15% reduction in the article processing charges for manuscripts accepted for publication.

Learn more about publishing with BMC.

View articles authored by Oberlin Group researchers already published with BMC, including commentary from Steven Bachrach of Trinity University, proposing "a plan that both reduces the total cost of publishing chemistry and enriches the literature through incorporation of Open Data."

Open Access Journals in Geosciences

Since October is a celebration of the geological sciences (Year of Science) it seems appropriate to check the Directory of Open Access Journals for titles in the earth sciences. Here's the subject breakdown of journal titles in the DOAJ:
Geography (52 journals)
Geology (66 journals)
Geophysics and Geomagnetism (9 journals)
Meteorology and Climatology (20 journals)
Oceanography (21 journals)

Advances in Geosciences
from the European Geosciences Union and Copernicus Publications is one of those general geology titles. From the publisher: "Advances in Geosciences (ADGEO) is an international, interdisciplinary journal for fast publication of collections of short, but self-contained communications in the Earth, planetary and solar system sciences..."

ADGEO has the Spark Europe seal, an indication that it uses Creative Commons license and provides metadata to the DOAJ, to ensure the widest possible harvesting of article content. In addition, ADGEO content may be archived in ADS: The Smithsonian/NASA Astrophysics Data System [example].

Open Access Week: Highlighting PLoS Biology

PLoS Biology, according to citation analysis on ISI Web of Science, has published 1,539 articles from its inception in 2003. All of them - every single one - readily accessible to anyone with an Internet connection and the ability to download either pdf or xml formatted materials. The actual number is undoubtedly higher, since there is a small lag time between publication in PLoS Biology and indexing in Web of Science. Those 1,539 articles have been cited a total of 39,089 times, including all of the "self-citations" -- or 32,522 times without counting the self-citations.

The most frequently cited paper, with 462 citations to date (again, using ISI data):
John B, Enright AJ, Aravin A, et al., 2004. Human MicroRNA targets. PLoS Biology 2(11): 1862-1879 e363. doi:10.1371/journal.pbio.0020363

Scopus reports 485 citations to this article, noted directly on the PLoS Biology site.

Far more exciting than simple citation analysis, though, is the potential for scholars and readers to interact, with options for commenting on and rating an article, jumping to related work, sharing the article through social networking tools, and finding similar research through guided searches in other databases. The PLoS article metrics includes the total number of page views for articles published after June 2005, giving another indication of the impact of open access.

The following article, for example, has been viewed 26,932 times:

Prior H, Schwarz A, Güntürkün O, 2008 Mirror-Induced Behavior in the Magpie (Pica pica): Evidence of Self-Recognition . PLoS Biol 6(8): e202. doi:10.1371/journal.pbio.0060202

The search and browse options on PLoS are easy to understand and highly effective; and the content is quickly found through Google Scholar, ensuring good reader access. I especially appreciate the Weekly Editors' Picks, which led to this article today:

Hoff M, 2009 Male or Female? For Honeybees, a Single Gene Makes All the Difference. PLoS Biol 7(10): e1000186. doi:10.1371/journal.pbio.1000186

Open Access Week Starts Today!

The Public Library of Science offers not just amazing peer-reviewed journal articles on a wide and growing range of scientific topics, it also provides a succinct definition of Open Access, which is nicely expanded at the Open Access Week web site. Once you've seen what PLoS offers, branch out completely by exploring the Directory of Open Access Journals (DOAJ).

Notice the statistics at DOAJ: As of today 319,631 articles are included in the DOAJ service, from 4370 journals. Do a search on Google Scholar - chances are, recent articles with high citation counts (i.e., many other authors cite those papers) are articles that were either published in an open access journal or have since been posted in an open access archive. Any search with a biomedical theme is bound to lead to BioMedCentral, with an abundance of open access research articles. More open access highlights will be forthcoming all week. For a detailed, yet highly readable explanation of open access, you can't go wrong with Peter Suber's account. Enjoy!

ObieSciLib is on Twitter! Keep in touch while you're on fall break.

The first day of Fall break is always very, very quiet in the library. If I was a student on campus I would certainly find something to do other than hide away in the library on this resplendent autumn day. The sun shimmering through green and yellow leaves outside the south-facing windows is very enticing. To the north, the wide spaces of north quad are filled with falling leaves, drifting across the empty green lawn. If you want to find out what excitement is happening inside, follow ObieSciLib on Twitter! (Okay, I lied, not much excitement at the moment.) If you do come indoors, you've got your pick of seats in the library and no competition at all for a computer. [photo from the Oberlin Science Center online tour]

Amygdala Regulates Perception of Personal Space

This month's issue of Nature Neuroscience features a report from researchers at California Institute of Technology, showing that an individual with "complete amygdala lesions lacked any sense of personal space." Someone with this type of damage to the amygdala region of the brain had an "abnormally small interpersonal distance preference." In other words, you might feel more than a tad uncomfortable while the other person leans in, seemingly unaware of the invisible personal boundary we erect between ourselves and others. [See earlier reports on this study at NPR Topics]

We manage to overcome the desire for personal space pretty quickly, at least for unavoidable and relatively brief periods of time (that sardine feeling in a crowded bus, say). Earlier studies documented the negative outcomes of persistent crowding stress (try a subject search on "crowding stress" in OBIS).

We do not subscribe to Nature Neuroscience online, so stop by the library and read the print issue. Learn more about the amygdala in The Human amygdala, edited by Paul J. Whalen and Elizabeth A. Phelps (on order for Oberlin's science library; request it through OhioLINK).

Two relevant, older books are available in our library: The Amygdala : a functional analysis and The Amygdala : neurobiological aspects of emotion, memory, and mental dysfunction.

Emperor Penguins Marching To Extinction?

The October issue of Oceanus arrived today - in print - and is now on the current browsing rack by our front door. Oceanus can be read online, of course, and it is a lovely web site. But the print magazine draws attention to new research and concerns that you might otherwise miss. The October cover shows brilliant shades of red and pink, a harmless dye dumped into a stream atop the Greenland ice sheet to track water flow through cracks in the ice, slicking the bottom of the glacier and hastening its demise into the North Atlantic. Inside, there are many other captivating photos and stories, including the worrisome conclusion that melting sea ice could reduce the Terre Adelie penguin colony from its present size of 3,000 to only 400 breeding pairs by the end of the century [from a study published online PNAS Jan. 26, 2009]. An enduring image from the documentary March of the Penguins is of the thousands of male penguins huddled in a mass, sheltering eggs from blasting, frigid winds -- survival dependent on having enough individuals creating that collective incubation zone. Declining numbers can't be good for this collaborative strategy of reproductive success.

Can you imagine eating 16 sugar cubes at one time?

One lump or two? How about 16 lumps of sugar? That is just a little less than the sugar contained in a 20-ounce bottle of cola. Ouch. Just one of the "20 things you didn't know about sugar" (and might have been happier not to know) presented by Rebecca Coffey in the Discover October issue. Amaze your friends with more "20 things you didn't know" on Discover's Web site.

The October issue is fun reading, addressing Great Questions of Science, including:
  • What lies beyond the edge of the universe?
  • Where have all the bees gone?
  • How does physics really work?
  • What controls the chemistry of life?
  • Did evolution shape us to be generous?
And, a special report on the neurology of sex. Did you know "the parts of the brain that light up during sexual experiences are associated with some of our most sophisticated forms of thought?" You can watch a video of brain activity at discovermagazine.com/web/sexinbrain.

Read the whole issue in the science library! Now on the new journals display rack.

Ribosomes, Proteins and X-Ray Crystallography: Nobel Prize in Chemistry

The Nobel Prize in Chemistry has been announced, and the intricacies of ribosomes as "protein-makers" in the cell are nicely explained in this Scientific American news article. Quoting from Scientific American news:"The prize will be equally split between biophysicist Venkatraman Ramakrishnan of the MRC Laboratory of Molecular Biology in Cambridge in England, biochemist Thomas Steitz of Yale University and molecular biologist Ada Yonath of the Weizmann Institute of Science in Rehovot, Israel, for their work in using x-ray crystallography to get a precise, atomic-scale map of the ribosome—the protein-making machine in all cells with nuclei that makes life possible."

You are who you are because of ribosomes (yeah, ribosomes!) - and, of course, all of those other countless biochemical processes occurring in your body right this second. Learn more about the ribosome's role in this electronic book: Structural aspects of protein synthesis / Anders Liljas.

Your Cell Phone, the Internet Backbone, Digital Cameras, all dependent on Nobel Prize winners

NPR's Richard Harris did a fine job of explaining the ubiquitous, essential nature of glass fiber optics and semiconductors, the research developments of three scientists who will share the Nobel Prize for Physics this year. The Nobel Committee said that the work of Charles K. Kao, Willard S. Boyle and George E. Smith made possible the "foundation of our networked society." The invention of the Charge-Couple Device or CCD (Boyle and Smith, working at Bell Labs in New Jersey) is a great example of scientists pursuing basic research, seeking a solution to a known problem, and discovering something very exciting with unforeseen benefits for the future. The CCD allows images to be captured digitally rather than on film. Kao's glass fibers, carrying information as light rather electricity, have literally transformed the world of information - certainly the work of librarians - and made possible development of the Internet.

Telomeres are the Focus of Nobel Prize Winners' Research

NPR's Morning Edition presented an excellent summary of the significance of the research of Elizabeth Blackburn, Carol W. Greider, and Jack Szostak, who share this year's Nobel Prize in Physiology or Medicine. "The scientists all study telomeres — structures that act like caps on the ends of chromosomes and protect them when cells divide. Chromosomes are the long strands of DNA that contain a living creature's genetic code." Elizabeth Blackburn of the University of California, San Francisco, is the subject of a recent book, Elizabeth Blackburn and the story of telomeres : deciphering the ends of DNA / Catherine Brady. MIT Press, c2007.

Learn more about the role of telomeres in aging and disease, in this electronic book accessible in the OhioLINK Electronic Book Center and at SpringerLink.com: Telomeres and telomerase in aging, disease, and cancer : molecular mechanisms of adult stem cell ageing / K. Lenhard Rudolph, editor. Springer, c2008.

An older book, The telomere by David Kipling, provides a good overview. Find it in the Science library [QH600.3 .K57 1995].

Celebrating Geosciences and Planet Earth: October in the Year of Science

We are celebrating the geosciences and planet earth all of October, as the Year of Science enters its last quarter. The planet, our very foundation and life-sustaining island home, so often under-appreciated as simply dirt beneath our feet, is an astoundingly complex system of transformative forces and myriad types of materials. Awesome power is displayed from the minute crystallization of igneous rock and the interplay of organic decomposition in sedimentary layers to vast movements of crustal plates. It is impossible to study earth science without an understanding of chemistry, physics, biology and evolution, at the least, and the geosciences inform all of those disciplines as well. Explore some of the big ideas in geology with the
We are also in the last part of the International Year of Planet Earth; and will observe Earth Science Week this month!

We have so many wonderful new books in the geology section, it is impossible to highlight more than a few. Start with The revolution in geology from the Renaissance to the enlightenment for a bit of historical context, and gain a better understanding of this continent with Ghost mountains and vanished oceans : North America from birth to middle age. Here are just a few more to entice you to read:
There is so much more - the Library's guide to geology research resources is a good place to start!

A Solar Panel That Produces Oil

This just arrived in my email from Scientific American, and was too intriguing not to share.
September 17, 2009
Oil Rig of the Future: A Solar Panel That Produces Oil
Researchers propose a novel approach to producing biofuel using diatoms

By Saswato R. Das
a brief excerpt:
"Scientific analysis of diatom oil has shown that it is very suitable for use as biofuel, says T. V. Ramachandra, a professor of ecological sciences at the Indian Institute of Science (IISc) who is working on this project with IISc researchers Durga Mahapatra and Karthick Balasubramanian, along with Richard Gordon, a radiology professor at the University of Manitoba in Winnepeg.

[Rmachandra says,] "The oil can be as much as a quarter of the total mass of a diatom cell, and if a way could be found to efficiently wrest it from diatoms, he adds, a hectare of "diatom cultivation could produce 10 to up to 200 times the oil that is produced by soybean cultivation."

Read the article and many comments that express both skepticism and support, at the Scientific American web site.

Want more information on algae as a biofuel? Search:
(algae or algal or diatom*) and biofuel*
in ISI Web of Knowledge (from an OhioLINK library). Over 70 references result, including a number of articles in oil trade publications and business sources as well as technical papers on algae bioengineering.

The library has many books on biofuels, including some ebooks:
Biofuels, solar and wind as renewable energy systems: benefits and risks / David Pimentel, editor. Springer, 2008.
Biofuels for road transport: a seed to wheel perspective / Lucas Reijnders, Mark A.J. Huijbregts. Springer, 2009.

These books, published by Springer, are accessible electronically from any OhioLINK library on the OhioLINK EBook Center. They can also be accessed by OhioLINK members at SpringerLink.com.

Michael Pollan on Health Care Reform

Living on Earth interviewed Michael Pollan this past week (author of The Omnivore's Dilemma and In Defense of Food), who argued that health care reform begins with improving what "we put on our plates."

Here is a snippet of the conversation, considering the difficulty faced by people on limited incomes who want to eat healthy food.
Pollan - "You can get 1,250 calories per dollar of chips or cookies but only 250 calories of carrots or broccoli. Um, that is due to the fact that the farm policies we have are favoring the really unhealthy calories. We subsidize corn and soy, which are really the building blocks of fast food. We subsidize feedlot meat, we do a lot to ensure that fast food is cheap. So, I think the personal responsibility argument breaks down pretty quickly and I think you really need to look at the environment in which we're eating and the system that is dictating the choices that we supposedly have."

Jane Goodall Trumpets Biodiversity on Diane Rhem Show

Why Study Biodiversity? - the big question of the focus for September in the Year of Science - was beautifully answered by Jane Goodall on the Diane Rhem show September 9. One remarkable example given by Ms. Goodall was the endangered burying beetle, which systematically buries carcasses that will provide food for its young and transports the tiny mites which eat fly larvae off the carcass. The marvels of co-evolution are evident in the life cycles of both beetle and mite, as well as the impact on the environment if that partnership is disrupted by the extinction of either.

Listen to the episode, and hear Ms. Goodall discuss the essential roles played by organisms of all types and sizes, the vast number of species in danger of extinction before they are even described or understood, and our dependency on biodiversity for maintaining healthy ecosystems that support human as well as other forms of life. A copy of Goodall's new book is on its way to the Science Library:
Hope for animals and their world : how endangered species are being rescued from the brink / Jane Goodall, with Thane Maynard and Gail Hudson.

Textbooks in the Science Library

Is your required science textbook on reserve in the Science Library? It's quite likely. We routinely look at the textbooks listed for science courses on the Oberlin College Bookstore website, and often decide to add the required textbook to the science library collection.

It is not guaranteed, however, and even if we do place the text on reserve your use is limited to 3 hours at a time and not for overnight use. So it does not take the place of owning your own book, with all of the benefits of being able to write in the margins, underline and highlight text to your heart's content, or read far into the night if necessary. We are just a bit more convenient than lugging around 1200+ pages of biochemistry (Voet and Voet is perhaps the heaviest text on reserve and one of the most popular for in-library reading).

Once you've found your textbook listed at the college bookstore, search OBIS and you'll see whether we own it and the course number for which it is reserved. Read all about reserve policies.

The Benefit of Doubt for Decision Making in a Civil Society

Doubt is an important part of scientific inquiry, in part because it causes the investigator to consider different variables and conditions necessary to test a hypothesis and evaluate research results. Sociologist Peter Berger argues (with not a small amount of certainty) that doubt is just as necessary in civil discourse. Listen to a provocative interview between Berger and Diane Rhem on the second segment of today's Diane Rhem Show (National Public Radio on WAMU.org). Podcast or transcripts are available approximately one hour after the end of the show.

From the Web site: "Civil discourse today is in danger of being shouted down by talking heads and single-minded bloggers. How doubt can help people on opposite sides of an issue to disagree more agreeably." Peter Berger is a faculty member at Boston University and founder of Boston University's Institute of Culture, Religion, and World Affairs. His newest book: In Praise of Doubt: How to Have Convictions Without Becoming a Fanatic. A very timely message as we witness the distinctly un-civil discourse around Town Halls on health care reform.

Find other books by Peter Berger in the college library [this newest title is not yet ordered].

One Man's Search for Natural Silence in a Noisy World

"Silence is not the absence of something but the presence of everything." So says author Gordon Hempton, acoustic ecologist, in the prologue to his new book One Square Inch of Silence (now on the new book shelf). Hempton's early work for the book was considered by another author promoting stillness during the June 13, 2003 edition of Living on Earth. Richard Mahler, author of Stillness, pointed out that "clinical studies confirm that stillness may also lower stress and blood pressure while promoting a sense of happiness and well being." Yet silence is vanishing from our lives and from even the most pristine wilderness. Gordon Hempton warns that the "unchecked loss of silence is a canary in a coal mine -- a global one. If we cannot make a stand here, if we turn a deaf ear to the issue of vanishing natural quiet, how can we expect to fare better with more complex environmental crises?"

A sound disc accompanies the book, so you can listen to the sounds of silence or the "silences of nature." I did, on one of the wonderful new Macs in our public computer area, which has remarkably good speakers. Twittering birds and crickets were clearly audible in the silence of a western preserve; then, the unmistakable rumble of distant traffic blurred the edge of birdsong. I suggest you try this without the distraction of multiple computers and the ever present hum of lights and the HVAC system in the science library - even in the middle of summer, without another soul in the library, it is not a peaceful silence.

Comet Calamity Considered in Sky & Telescope

The July issue of Sky & Telescope just arrived, in time for the last few days of July's theme: Celebrate Astronomy! as part of the Year of Science. The cover, by S&T artist Casey Reed, is sure to draw you in, illustrating the question "Did a comet wipe out early North Americans and the huge beasts they hunted?" How can you resist such a provocative query? "Demise of the megabeasts" indeed - and what role was played by the Clovis people thought to be in North America at the time? Those "ice age big game hunters" were sophisticated predators, notes Paul Martin of the University of Arizona.

Science is so fascinating when astronomy, geology, paleontology and anthropology mesh together like reading a good mystery or detective story.

The article, Ice Age Impact, was written by Ivan Semeniuk. Listen to a podcast of scientists who were interviewed for the article at SkyandTelescope.com/iceageimpact.

NPR Interviews Natl Geographic Spelunker and Photographer Stephen Alvarez

National Public Radio unveiled its re-imagined NPR.org site today and a host of great stories are suddenly at your fingertips. I was immediately drawn to The Picture Show, featuring "Caves, Cameras, and Explosives," and applaud NPR's collaboration with National Geographic to broaden the audience of photographer Stephen Alvarez. I was entranced by all of the photos, from the sublime and awesome to the arguably undignified (the shot of a spelunker's feet in the air, upper torso down a hole is such a great contrast to the grandeur of spelunker suspended in Ellison's Cave, Georgia). The feature article, "Deep Southern Caves" by Mark Jenkins was published June 2009, and can be perused in print in the Main library (Azariah's Cafe popular magazine collection) or explored online.

PLoS One Projected to Become Largest Scholarly Journal Worldwide

This message was sent by Heather Morrison today, with exciting news regarding one of the newest journals from the Public Library of Science (PLoS):

"PLoS One is projected to publish about 4,300 articles in 2009, making it the world's third largest journal (and already the world's largest non-physics journal). In 2010, PLoS One is anticipated to publish 8,000 articles, which would make it the world's largest scholarly journal, by far.

"One of the world's other really large journals - the American Physical Society's Physical Review D - is on the list of journals 100% convertible to the SCOAP3 Open Access Consortium. So it is entirely possible that TWO of the world's dozen largest journals will be fully open access within the next year or so."

A Plethora of New Books

The July shipment of books offers enough reading for this summer and the next three, possibly, in nearly every subject area of the Science Library. Books on worms, hedgerows, nutrigenomics, chaos mathematics, corridor ecology (and that doesn't refer to mold and mites in the hallway in your building), evolutionary genetics, Einstein, color, atmospheric thermodynamics, molecular networks, polymers, the Medea hypothesis, fluvial systems, hormones, Valles Caldera, marsupials, stem cells, wild mushrooms, phytoplankton, ants, bioinorganic chemistry... the list could go on and on!

Farming with nature or Organic agriculture might be the most seasonal of titles, along with Fresh: a perishable history, as we are in the midst of the northern growing season and harvesting local produce already.

Check out the new books list and borrow something interesting for summer reading!

YoS July: Celebrate Astronomy!

The Year of Science focus for July is ASTRONOMY, and our shelves are overflowing with great, new books on the subject. Do a subject search, limited to 2007-2009, in OBIS.

The Day We Found the Universe
is one of dozens of books received in our latest new books shipment. From the book overview in Google Books [link there from OBIS]: "On January 1, 1925, thirty-five-year-old Edwin Hubble announced the observation that ultimately established that our universe was a thousand trillion times larger than previously believed, filled with myriad galaxies like our own."

This is a fascinating account of early astrophysics. Follow that historical review with books on current research, perhaps a title on Kerr black holes.

2009 is also the International Year of Astronomy (IYA). The U.S.A. web site for IYA offers Galileoscopes to commemorate the 400th anniversary of Galileo’s use of a telescope to study the skies.

The web site includes a calendar of current and historical events in astronomy, including moon phases and positions of observable planets in the night sky. Full moon, Tuesday July 7 at 3:21 a.m. Later that day (4pm) the moon will be at Apogee. Learn more about the difference between Apogee and Perigree.
