The 2006 Goldwater Scholars were recently announced on the Barry M. Goldwater Scholarship web site. We are pleased to see three Oberlin students on the list, and especially happy for Tymoteusz (Tim) Kajstura, who is currently on the science library student staff and ably serves at both the circulation and reference desks. Tim is a Neuroscience/Biology major who intends to pursue graduate studies in Neuroscience. He hopes to "conduct research focusing on topics with direct consequences on human health and welfare from a biological perspective." Great work, Tim!
Congratulations also to Daniel Hemberger, Physics/Music Performance major and Andrew Bartholomew, Computer Science/East Asian Studies major, the other Goldwater scholars from Oberlin this year. Both students intend to pursue graduate studies in science, in astrophysics and computer science, respectively. Chris Boyd, Chemistry/Biochemistry major, received an honorable mention and intends to pursue a Ph.D. in Synthetic/Physical Organic Chemistry.
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)

Mitch Earleywine's Mind-Altering Drugs answers the question "What is the nature of intoxication?" It is a thorough and accessible review of the subjective nature of drugs, explaining that each substance may create a different effect with every administration in each user.
In How Fat Works Dr. Philip A. Wood reviews recent research about specific genes or groups of genes that can lead to matabolic disorders. Wood is an experimental pathologist and molecular geneticist who uses gene-knockout technology to study the way mouse genes regulate the metabolism of fat. His book reviews the complex interplay of hormones, genes, and stress in the way human bodies deal with fat through the life cycle.
Each week Nature publishes a free audio show, presented and produced by Chris Smith and Anna Lacey at the University of Cambridge, UK, and sponsored by Bio-Rad.
Each show features highlights from news and articles published in Nature, including interviews with the people behind the science with in-depth commentary and analysis from journalists covering the research.

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."

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.

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."

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.

Protesters March to a Different Drummer
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.

Over 250,000 Petition Forest Service to Reinstate Forest Protections
Olympians Join Effort to End Bush Administration’s Logging and Drilling Efforts
More than a quarter of a million Americans today formally petitioned the Bush Administration to reinstate a rule protecting roadless areas on America's National Forests. In an unprecedented move, conservationists, concerned Americans and more than 100 current and former Olympians used the Administrative Procedures Act (APA) to petition for a policy reversal. The APA grants citizens the right to request that the government issue, amend or revoke federal rules. Read the full story at the Wilderness Society site

Monitoring cyclodextrin–polyviologen pseudopolyrotaxanes with the
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,
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
