Penn State Live recently posted this article... it explains the Time Tree of Life a lot better than I can! -- The book will soon be available at Penn State University Libraries.

New initiative traces the beginning of species' life on Earth

Wednesday, June 10, 2009 University Park, Pa. -- Beginning this week, scientists and nonscientists now have easy access to information about when living species and their ancestors originated, information that previously was difficult to find or inaccessible. Free access to the information is part of the new Timetree of Life initiative developed by Blair Hedges, a professor of biology at Penn State University, and Sudhir Kumar, a professor of life sciences at Arizona State University. The Timetree of Life project debuted this week with the simultaneous release of a major online resource called "TimeTreeWeb" (http://www.timetree.org), and a book titled "The Timetree of Life" (Oxford University Press), which is written by a consortium of 105 experts on specific groups of organisms and is edited by Hedges and Kumar. Nobel laureate James D. Watson, co-discoverer of the structure of DNA, comments in his foreword to the book, "I look in wonder at The Timetree of Life, at the breadth of life that it covers, and the extraordinary data presented in it." 

"The ultimate goal of the Timetree of Life initiative is to chart the timescale of life -- to discover when each species and all their ancestors originated, all the way back to the origin of life some four billion years ago," Hedges said. Many researchers long have studied the times of origin of individual species in order to piece together a Tree of Life, but now the Timetree of Life project provides a synthesis of the time-calibrated Tree of Life, in addition to adding much new information from previously unpublished scientific studies.

One fifth of "The Timetree of Life" book contains new data, published for the first time, which fill many gaps in the family tree of life down to the taxonomic level of "family" (groups of species). For example, the book's chapter on stingrays and sharks is the first published timetree analysis of the existing molecular data about these animals. Almost all of the previously published data reviewed in the book became known only recently, in the hundreds of scientific articles published during the past five or ten years.

Each chapter of "The Timetree of Life" book is a review of the evolutionary history of the families within a particular group of organisms, such as mosses, ferns, fungi, beetles, sea urchins, frogs and toads, turtles, owls, primates, and many others. The chapters each contain a photograph of a representative organism, a color-coded timetree showing how the families are related and when they split from their closest relative, and a table with divergence times. Each chapter of the book was subjected to a rigorous scientific review by other experts in the respective field..

Support for developing TimeTreeWeb has come from the U. S. National Science Foundation, the Astrobiology Institute of the U. S. National Aeronautics and Space Administration, the Science Foundation of Arizona, and the Biodesign Institute of ASU.

The winners of the Webby Awards were announced yesterday and I noticed a few blog.li.og.ra.phy favorites in the winner columns!

Notably, TED in the category of Best Use of Video or Moving Image and FactCheck as the people's choice for best website in Politics. The Huffington Post was the Webby winner in the Politics category. The Guardian (UK) was the winner in the Newspaper and Podcasts categories, with the New York Times was selected as the People's Voice winner in the Newspaper category and Webby winner for Best Copy/Writing, among others.

Even better, looking through the list of Webby Award winners and nominees I discovered some cool new websites!

Exporatorium (The Museum of Science, Art and Human Perception)
Evidence: How Do We Know What We Know? A Case Study in Human Origins -
Science and Education nominees
I can't say it any better than they do: "This project uses case studies to examine how scientists construct a functional understanding of the world by gathering, assessing, and making use of scientific evidence."

SmARThistory - Education Webby winner
"[A]a free multi-media web-book designed as a dynamic enhancement (or even substitute) for the traditional art history textbook." Fun and educational!

Wired Science blog - Science People's Voice winner
Even though I love Wired magazine (People's Voice winner in the Best Copy/Writing category), I don't regularly read the science blog. Some very cool stuff here, even for a non-scientist like me. It also makes good use of photos and video, which gets a thumbs up in my book. (If it wasn't so time consuming, I would do it here more often!)

The Atlantic - Magazine Webby winner
I'm a fan of the magazine, but never spent any time on their website. A great place to look for research ideas or get your research project started!

Less research-related, but still highly recommended is...

NPR Music - Webby and People's Voice winner
NPR is also Best Radio Webby winner and Best Podcast People's Voice winner

This is the 13th year the International Academy of Digital Arts and Sciences has honored excellence on the Internet with their Webby Awards. So much good information, so little time!

Maybe you're not familiar with this Jackie DeShannon song, but during finals week on a college campus I think sleep is something we could all use a little bit more of.

Since sleep is an issue that has plagued me for my entire life, it's a subject I am always interested in. So, now seems like the perfect time to write about a series of guest columns about sleep and our natural circadian rhythms by Leon Kreitzman on the New York Times' Wild Side blog.

The first, "Larks, Owls and Hummingbirds" (April 21, 2009), explains that 70-80% of us are 'hummingbirds' and are easily able to reset their internal clocks, but the remaining early-rising 'larks' and late-to-bed 'owls' have difficulty doing so. This article could make an excellent starting point for your research, as it includes references to numerous studies on the subject, as well as recommended books and articles.

The second article, "Let's Hear It For the Bees" (April 28, 2009), discusses honey bees' sophisticated circadian "clockwork" that allows them to keep track of the time of the day different flowers open, but also the time of the season each flower blooms. You can read more about the honey bee elsewhere on this blog.

A true reference classic, The World Almanac and Book of Facts has been published for well over 100 years, 140 to be exact.

Each annual issue has a recap of major events from the previous year, as well as statistics and facts about:

• Economy, Business, & Energy
• Crime
• Military Affairs
• Health & Vital Statistics
• Personalities, Arts & Media
• Science & Technology
• Consumer Information
• U.S. Government
• U.S. Facts, History & Elections
• U.S. Cities, States & Population
• World History & Culture
• Sports

Some interesting facts and figures I discovered while glancing through...

• Penn State University Libraries have the 33rd largest library collection in the U.S.!  (p. 404)
  
• Total fat consumption in the U.S. has risen from 37.7 lbs per capita in 1910 to 85.5 lbs in 2005   (p. 87)
• Women and children make up 70-80% of the estimated 24.5 million internally displaced persons worldwide  (p. 850)
• The winning word in the 2007 Scripps National Spelling Bee was "serrefine"  (p. 722)
• The most popular names given to babies born in the U.S. in 2006 was Jacob for boys and Emily for girls  (p. 726)
• In 2006 the U.S. produced 71.03 quadrillion Btu of energy, but consumed 99.87 quadrillion Btu of energy, 85% in the form of fossil fuels and only 6.8% in the form of renewable energy sources (figures are preliminary, see the Annual Energy Review for more details)  (p. 104)

In an introductory essay entitled, "The Almanac in the Internet Age," C. Alan Joyce and the Editors of the Almanac write:

"So how does a book like The World Almanac survive, in a world where terabytes of information are a mouse-click away, where reference books can be tagged as suspicious and dangerous tools, and where people rely more on "gut feelings" than rational, informed discussion? By doing much the same thing is has done for the past 140 years: by filtering through massive quantities of data to bring its readers only the most essential statistics, in readable format; by delivering authoritative, reliable facts and practical information; and by avoiding, as much as humanly possible, the modern urge to editorialize and manipulate data to support a particular point of view.

"In compiling each new edition, we stumble across countless surprises and unexpected revelations about the world; a casual flip through the pages of this volume should let you follow the same journey of surprise and discovery."  (p. 7)

I think this says it all. In fact, the way they feel about their almanac is the way I feel about reference books and libraries in general, and I don't think I'm alone. A decline in use of our print reference collection cannot change how I feel about these books. Though the format may not always be practical in the "Internet Age," some books are just easier to use in print--at least until searching, viewing, and browsing options improve. I'm not sure anything will ever quite replace the "journey of surprise and discovery" that comes with flipping open a book to a page at random or thumbing through its pages until something catches your eye.

Whether "hidden" inside a book stored on the shelves in the library's reference collection or "hidden" behind a link to the library's subscription to the e-book, the content of these books is still highly valuable and relevant. This is what keeps me motivated to continue the "Reference Special" feature, to encourage a student demand for quality by raising awareness of "hidden" information sources. Stay tuned.

What's causing the massive bee die-offs that are threatening American agriculture? Penn State researchers are working tirelessly to find answers.

An in-depth article about "Colonies in Collapse" recently appeared on the Research Penn State website. Honey bees are a "keystone" species upon which many other species depend (including humans), and they are depended upon to pollinate over one hundred different fruit and vegetable crops estimated at more than $14 billion. Currently, Colony Collapse Disorder (CCD) has been identified in 27 U.S. states and Canada, as well as countries across Europe.

Penn State has emerged as a leader in CCD research, with nineteen faculty and graduate students in various agriculture and science departments currently doing research on bee health. See the complete "Colonies in Collapse" article for more details.

I originally wrote about the vanishing honey bees in September 2007.

Today I'm in a rush, I have a lot to do! It probably took me longer to select a reference book to write about today than it will take for me to write this. So, this got me thinking about hurrying... what helps when you're in a hurry? I have a lot of ideas about this, but I settled on something that will help you say a lot in a short amount of time (and space).

Recently I was talking with a class about how a picture can say 1,000 words. Along those same lines, starting out with a short, pithy quote can really set the tone for what you're trying to say.

I distinctly remember being introduced to quotation dictionaries in junior high. (Oddly, this is not the first time today that a memory of junior high was triggered!) It was one of the few times I ever went into the school's library after elementary school--a class trip, probably for English class. My memory is foggy, but it goes something like, "Wow! Abraham Lincoln said that?!"

Some of you may already be familiar with Bartlett's Familiar Quotations, but I grabbed a more modern volume--The Oxford Dictionary of American Quotations (Ref. PN6081.A623 2006, Eiche Library Reference Collection).

They way they work is you look up the idea, place, person, or quality you're interested in and the book will give you a selection of famous and/or meaningful quotes to choose from. What's unique about this particular title is that (from the "Introduction," p. vii), "It is a collection, organized along historical lines, of nearly six thousand memorable quotations on more than five hundred some aspects of American life and culture."

So, under the entry for "love," you can read what Benjamin Franklin had to say about love in 1755 ("If you would be loved, love and be lovable.") -- what Emily Dickinson had to say about love in the 19th century -- and what 20th century icons like Robert Frost have to say ("Love is an irresistible desire to be irresistibly desired."). Humorously reflecting what may be a 20th century attitude toward love, comedian Lily Tomlin said "If love is the answer, could you rephrase the question?"

The words of Golda Meir speak to me: "I must govern the clock, not be governed by it."

Didn't find what you were looking for? The book also has a keyword index in the back, either for quick scanning or to find "Tippecanoe and Tyler too" (Whig campaign slogan, 1840) under the heading "political slogans" (see p. 514 to learn what that means). In the author index you can find direction to all those thoughtful Lincoln quotes. Maybe one will trigger more memories of 8th grade for me!

I could write a year's worth of entries about the wonders of titles in the language section of our reference collection, so stay tuned.

I missed an edition last Friday because I was out of town for a meeting, but, who's counting? This week I thought I'd take a look at a new classic, The Way Things Work, which many people probably had a copy of at home at one time or another, and some related books that tell the story of inventions.

Encyclopedia of Modern Everyday Inventions (Ref T20.C56 2003)
A History of Invention: From Stone Axes to Silicone Chips (Ref T15.W718 2000)
The Way Things Work (Ref T47.M18 1988)

These books will give you a sense of how the creativity of inventors (and the virtue of necessity) have impacted our world, as well as a better appreciation for the everyday items we take for granted.

You may know how to play an electric guitar, but can you explain how it works? You could use these books to incorporate a deeper understanding of how an electric guitar works into an informative speech or paper on the subject, or see how we got from parchment (untanned skin of sheep or goats) to blogs for communicating ideas.

But another use of these books could be research for a creative writing project. Use the books to understand the technology of the time and your wordsmithing to create a vivid picture when writing historical fiction. Or, use an understanding of how past inventions have changed our society to predict the impact new inventions might have for a story set in the future. Think about how light bulbs and sewing machines changed our lives... or how few people really understand the engineering behind anything well enough to build a working vehicle or a means of communicating remotely out of nothing, or even with some spare parts. (Ever seen Lost?)

And if those uses don't work for you, impress someone with your knowledge of, say, how a breath tester works. We all know you breathe into it and it, basically, it tells you how much you've had to drink--but what happens in between? Check out p. 314 of The Way Things Work to find out. (Nod to HowStuffWorks.com.)

Have you been wondering... how did we get from the mimeograph to the xerox?
Recently we've had a number of students asking what a "mimeograph" is and how they can make one. We directed them to the photocopier, but for the record, mimeograph was invented in 1875 by Thomas Alva Edison and was a "mainstay in office and school duplicating for the next century" (p. 83, Encyclopedia of Modern Everyday Inventions).

Stay tuned.

This week I've been thinking about law, but it's such a cold, gray day that I think I will save that topic for later. Instead, I thought I would take a look at atlases today.

Atlases are a lot more than the tattered collection of Rand McNally road maps from 1986 shoved under the front seat of your car. They are also rich visualizations of the subject at hand. They help you see the "big picture," and are usually accompanied by a "big picture" essay that weaves the maps into a story.

Atlases also combine two things I love--maps and numbers--so I could spend all day pouring over these.

For those of you who like to browse the shelves, all the atlases are usually together in the geography section (G call numbers). So, an atlas of American history won't be with the American history books, it will be with the atlases. This is a good example of why it's good to start a search for books by looking in the catalog (The CAT) for all the books on your topic. Add the word "atlas$" ($ truncates your search, to find either 'atlas' or 'atlases' in the description) or the word "maps" to your search to find atlases on your topic.

A few of the atlases in the Eiche Library Reference Collection:

Mapping America's Past (1996)
Check out "Prostitution in 19th-Century New York: Victorian Gender Ideology" (pp.140-141) or "The Geography of 'Stupidity': 'Intelligence,' Race, and Illiteracy" (pp.166-167)

Atlas or World Art (2004)
For example, "Art, War and Empire: The Aegean, 500-300 B.C." (pp. 60-61) - see the sources of metals, the trade routes, and major construction sites as advances in shipbuilding and navigation allowed for more trade in modern-day Greece and Turkey and the rise of communities and wealth led to an increase in skilled craftsmen (artists) (think: The Parthenon and giant marble statues)

Atlas of the World (2005) -- on the Atlas Stand, along the left wall on the 2nd Floor
Check out star charts and the 22 nearest nearest stars or maps depicting continental drift and geologic time, as well as maps of the world's countries and major cities and an index of locations.

But I wanted to take a little closer look inside the New Historical Atlas of Religion in America (2001). Based on the title and brief catalog description of the item ("ecclesiastical geography" and "church history") you do find what you might expect...  all sorts of maps and essays about the history of Baptist churches, Methodist churches, Roman Catholic churches, Jewish synagogues, Muslim mosques, and the list goes on. Name a religion, it's probably in there.

What I wasn't expecting to find were sections on "Native Americans" before (Section 1, pp. 30-34) and after (Section 2, pp. 113-121) 1800, because they're looking at both "institutional" and "ethnic" religions in this book. The sections describe the rise, spread, eventual fall of numerous religious movements in the Native tradition, including the spread and use of the hallucinogen peyote in the 19th and 20th Centuries. The legality of the use of the drug as part of Native American Church worship has been contested throughout the 20th Century, recently in the 1988 Supreme Court case Employment Division v. Smith.

They're so packed with information, atlases just may be the "ultimate" reference book. Since they are so dense, how do you go about finding what you are looking for? My advice would be to ask for help and to plan to spend a little bit of time looking! You will be richly rewarded for the time invested.

In the second installment of the "Reference Special," I'd like to take a look at a new classic: African American National Biography, edited by Henry Louis Gates, Jr. and Evelyn Brooks Higginbotham (Ref. E185.96.A4466 2008 v.1-8 and online in the Oxford African American Studies Center (link to PSU subscription)).

First off, I became a big fan of Henry Louis Gates, Jr. after seeing the African American Lives program on PBS. I wrote about it here--you can check out African American Lives and African American Lives 2 on DVD from the library. Gates is a Harvard professor and prolific author, among many other accomplishments.

This set is a much needed companion to the classic biography reference set American National Biography (Ref. CT213.A68 1999 v.1-24 and online at American National Biography (link to PSU subscription)).

"African American National Biography presents history through a mosaic of the lives of 4,100 individuals, some known throughout the world and others all but forgotten, illuminating the abiding influence of African Americans on the life of this nation through the immediacy of personal experience." (AANB website)

One of the great features of the printed set are the rich indexes found in Volume 8. There is an Index by Birthplace, as well as an Index by Subject Area and Realm of Renown with topics ranging as broad as Art, Award [Winners], Business, and Sports, to focused areas like Slave Narratives, Music-Hip Hop, and Women's Activism. Finally, there is a quick reference section on "African American Prizewinners, Medalists, Members of Congress, and Judges."

For students interested in history, this is a great resource for exploring beyond the well-know figures. In addition to Harriet Tubman, Rosa Parks, Martin Luther King, Jr., Malcolm X, Muhammad Ali, W.E.B. Du Bois, Sojourner Truth--discover other activists, athletes, educators, soldiers, politicians (and the list goes on) that have contributed to our nation's rich history.

For example, I selected an entry at random and learned a bit about the life of Isaac D. Williams (1821-1898) as he struggled to find his way from slavery to freedom, ultimately becoming a successful businessman and entrepreneur (v. 8, pp. 324-325). Find out more about Williams by reading his narrative, Sunshine and Shadow of Slave Life, made available online by the University Library of the University of North Carolina at Chapel Hill's North American Slave Narrative Collection in their Documenting the American South repository of primary sources.

There are many, many other fabulous resources for researching American, and specifically African American history. I'll recommend just one, the Oxford African American Studies Center (link to PSU subscription). Self-proclaimed to be "the online authority on the African American experience," this rich resource contains:

• more than 8,000 articles from numerous books
• over 1,750 images
• more than 300 primary sources (including commentaries)
• nearly 150 maps relevant to the content
• 150 charts and tables

And the research center continues to grow with new entries, presumably even before available in print. Finally, it is worth periodically checking back in on this resource for its Feature of the Month, currently "Blacks in Politics, Part 1." In the photo essay portion of the feature, the author refers to Barack Obama as "the first black and biracial man with a high chance of being the next President of the United States," which really struck me because I don't think I have ever heard the media refer to the Presidential candidate as biracial, only black, raising lots of questions about how we have historically, and continue, to perceive race on our society. (Note: Turns out a few media outlets are talking about it, sometimes in reader comments/reactions pointing out an oversight in the article. An interesting report on research related to this topic was published just today on Science Daily, "Does It Matter if Black Plus White Equals Black or Multiracial?"

I've wandered far from my original topic! But, I guess that only demonstrates how far a little research can take you.
