Cover stories from journals received in the library this week



Science, 24 March 2005, features Climate Change: breaking the ice on its front cover. Four research reports, a news story, and the editorial all address the science of declining ice sheets in Greenland and West Antarctica. Read the library's print issue or go online.

A photograph of a breaching narwhal, tusk in the air, graces the cover of Science News, 25 March. The narwhal's left tooth can grow to 3 meters in length and is the only spiraling tooth ever reported. Recent research suggests that the tusk's main function is environment sensing.

An Arctic Fox with a seabird in its mouth (the Least Auklet) peers from the cover of Ecological Monographs, Feb. 2006. This predator, along with the Norway Rat, introduced to the Aleutian Islands some 150 years ago, has demolished native populations of seabirds.

"What are we doing this for?" asks Tim Flannery in Fresh Air Interview

Tim Flannery, author of The weather makers : how man is changing the climate and what it means for life on earth asks the question when interviewed by Terry Gross on Fresh Air, 22 March. By "this," Flannery means global warming, and he goes to ask "is it simply to drive SUVs and waste electricity? That's madness." Hear the interview in the NPR archives. Borrow the book from the science library for a critical analysis of the multiple, undeniable indicators of the human impact on global climate.

Global Warming is the subject of Living On Earth

Living on Earth considers the impact of global warming on far-flung environments around the planet, from Lake Tanganyika in East Africa to Manitoba on the shores of Hudson Bay. The first two segments of the series Early Signs: Reports for a Warming Planet, are available as written transcripts, MP3 audio files or audio streaming, and are well-worth the time for careful listening (or reading). The stores are archived at salon.com. Climate change, and global warming specifically, are given a thorough investigation by Elizabeth Kolbert in her book, Field notes from a catastrophe : man, nature, and climate change. New York : Bloomsbury Pub., 2006. Her book first appeared in the New Yorker, and was the subject of a May 9, 2005 talk between Alex Chadwick and NPR science correspondent Richard Harris.

Encyclopedia Britannica or Wikipedia? Study in Nature is said to be inaccurate.

From BBC News:
Wikipedia study 'fatally flawed'

"A study on the accuracy of the free online resource, Wikipedia, by the prestigious journal Nature has been described as 'fatally flawed'.

"The report, published in December last year, compared the accuracy of online offerings from Encyclopaedia Britannica and Wikipedia. Nature found that both were about as accurate as each other on science. <Read the Nature report>

Encyclopaedia Britannica has hit back at the findings, calling for the paper to be retracted." <Read the full BBC news story>

The report in Nature has sparked at least two letters in response, suggesting ways to utilize wiki software to benefit science and facilitate scientific research:
Gene-function wiki would let biologists pool worlwide resources.
(2 Feb.);
Wiki ware could harness the internet for science. (16 March)

New Questions on Dino to Bird Evolution

Science News from Scientific American

Scaly Dino Find Complicates Feather Evolution


"Paleontologists working in the same area of Germany that yielded Archaeopteryx have discovered a new small theropod dinosaur. The nearly complete specimen--dubbed Juravenator starki--is one of just a few known fossils representing this group, which ultimately gave rise to modern birds. Indeed, it joins just two partial skeletons of another genus as the only European examples of the tiny carnivores. Unlike the other two specimens, however, it lacks any sign of feathers, complicating what researchers thought they knew about feather evolution."

Embryonic inner ear cells use migratory mechanisms to establish cell patterns in vitro.
Bianchi, Lynne M. (Neuroscience Department); Huri, Daniela; White, Ian O.

Journal of Neuroscience Research 83(2): 191-198. February 1, 2006.

Abstract:

The hair cells of the sensory epithelium in the inner ear are among the most precisely organized cells in vertebrates. The mechanisms that lead to this orderly arrangement are only beginning to be understood. It has been suggested that hair cells use migratory mechanisms to help achieve their final position in the organ of Corti. In the present study, an established in vitro assay of dissociated, embryonic inner ear cells was used to monitor how hair cells reorganize over time. © 2005 Wiley-Liss, Inc.

Union of Concerned Scientists Lead Effort to Support Endangered Species Act

From the Union of Concerned Scientists
5,738 Scientists Decry Attempts to Weaken Endangered Species Act: Leading Biologists Release Sign-On Letter

Leading scientists have released a letter signed by 5,738 biologists across the United States urging the Senate to stand by scientific principles that are crucial to species conservation in the Endangered Species Act (ESA). The letter--representing scientists from all 50 states and more than 900 institutions--asks Congress to stop efforts to weaken the ESA.

"Thanks to a strong scientific foundation, for 30 years the Endangered Species Act has protected wildlife, fish and plants on the brink of extinction," said Dr. Stuart Pimm, Doris Duke Chair of Conservation Biology, Duke University. "We should protect biodiversity by strengthening and fully funding the ESA, rather than attacking it."

News: Microbes in Hydrothermal Systems Give Clues to Life's Origins

Researchers find ways heat-loving microbes create energy.

Curiosity about the microbial world drove Jan Amend, Ph.D., associate professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, to Vulcano Island, Italy, a shallow hydrothermal Shangri-la near Sicily. There, Amend and his collaborators managed to examine the environment in depth, design a gene probe, and discover new life–which could have some big implications for the origin and presence of life on Earth.

Science News Today: Animal Research Gains Supporters

ANIMAL RESEARCH:
Protesters March to a Different Drummer
Eliot Marshall

OXFORD, U.K.--A placard-waving crowd took to the streets here on 25 February with an unusual message: Support animal research. Several hundred people showed up, among them a few speakers from the University of Oxford faculty, including neurosurgeon Tipu Aziz (surrounded by a crowd, right). The idea for the rally came from 16-year-old Laurie Pycroft, who describes himself as an Internet blogger and fan of science. Angered by an encounter in January with protesters seeking to halt construction of Oxford's $34 million life sciences lab, Pycroft decided to respond with a pro-lab march. The idea caught on. The same day, opponents of the lab staged a rally several blocks away; police kept them apart. (Read more)

Effects of Functionalization, Catenation, and Variation of the Metal Oxide and Organic Linking Units on the Low-Pressure Hydrogen Adsorption Properties of Metal-Organic Frameworks

J. Am. Chem. Soc. 128(4); 1304-1315.

Jesse Rowsell is a Research Associate in the Chemistry department. He contributed this summary of his recent article:

Realizing hydrogen's potential benefits as a fuel has been a hot topic of research, especially following President Bush's announcement of the $1.2 billion Hydrogen Fuel Initiative. It is widely recognized that several key advances are necessary in the areas of hydrogen production, storage, delivery and conversion. In order for hydrogen to be considered a viable alternative for fueling our transportation sector, new storage technologies must be developed to pack more of the gas into a smaller container. One strategy has been to develop microporous adsorbents that bind hydrogen molecules in molecular-sized holes. This paper evaluates the adsorption behavior of several new hybrid compounds that are composed of metal ions linked with organic molecules in a "Tinkertoy" fashion. It is shown that altering either the organic or inorganic components can improve the binding potential for hydrogen.

Monitoring cyclodextrin–polyviologen pseudopolyrotaxanes with the Bradford assay.
Organic and Biomolecular Chemistry 4 (2): Jan. 2006. pp. 250-256.

This paper reports on Jason Belitsky's post-doctoral research at California NanoSystems Institute and Department of Chemistry and Biochemistry, University of California, Los Angeles. It can be downloaded from the OhioLINK Electronic Journal Center.

Abstract: Self-assembled multivalent pseudopolyrotaxanes, composed of lactoside-bearing cyclodextrin (CD) rings threaded on linear polyviologen polymers, have been introduced recently as flexible and dynamic neoglycoconjugates. In the course of this research, it was found that polyviologens are responsive to the Bradford assay, which is traditionally highly selective for proteins. The response of the pseudopolyrotaxanes to the Bradford assay was dependant on, and thus indicative of, the degree of threading of the CD rings onto the polyelectrolyte. The assay was then used to report on the threading and dethreading of native and lactoside-bearing a-CD rings onto and off of polyviologen chains, a phenomenon which demonstrates the utility of biochemical assays to address problems unique to supramolecular chemistry.
