Science News digital edition in Wiley Online Library

The complete digital edition for subscribers of Science News is now part of the Wiley Online Library.  Free content remains available at sciencenews.org, including Web-only multi-media enhancements, but the Wiley Online Library archive is our location for downloading pdf versions.
 
The September 11 issue includes an article of conflicting reports between scientific teams working in the Gulf of Mexico:

Library Hours during Orientation Week

As we prepare to welcome new students to campus tomorrow, today is, figuratively, our last day of summer.  New beginnings!  Library hours are a bit extended this week to accommodate departmental open houses held in the library and course registration in the iMac lab.

• Monday - Wednesday  9 am-noon, 1-4:30 pm
• Thursday 9 am-7 pm
• Friday 8 am-noon, 1-4:30 pm

15-minute orientation tours for new students will be offered continuously beginning at 1 pm on Friday.  The last tour starts at 2:30 pm.  Hope to see many new science-minded students on Friday afternoon!

Cruz lab research in Developmental Biology

Three new abstracts of research by Yolanda Cruz, Professor of Biology, as indexed in Web of Science are included in the August 1 issue of Developmental Biology.  The abstracts summarize presentations made at the 69th Annual Meeting of the Society for Developmental Biology, held earlier this month in Albuquerque, NM.  Neils Bantilan, Jeremy Morrison, Vicki Wang and Joanna Johnson are (or were) Oberlin College students who conducted research with Professor Cruz.

van der Heide publishes in Journal of Cell Science

Dana van der Heide, a rising senior Biology major, is co-author of a paper published online June 22 in the Journal of Cell Science.  Unfortunately, Oberlin does not have a subscription to this journal, published by Cambridge Univ. Press, but the abstract is accessible at the publisher's site.  Congratulations to Dana on her research and scholarship.

Whelan article in Tumor Biology on ovarian cancer biomarker

The most recent article published by a member of the science faculty, in collaboration with three undergraduate students, appears in Tumor Biology [online first].  Rebecca Whelan is Assistant Professor of Chemistry and Biochemistry.

Zach T. Berman, Lee J. Moore, Kathleen E. Knudson and Rebecca J. Whelan.  Synthesis and structural characterization of the peptide epitope of the ovarian cancer biomarker CA125 (MUC16).  Tumor Biology.  Published online Monday, June 21, 2010.    DOI  - 10.1007/s13277-010-0062-4
   http://www.springerlink.com/content/Q4740054V36410R6 [abstract and page 1 only are accessible to non-subscribers]

Whelan's research advances understanding of the structural characterization of CA125, particularly the amino acid sequence and oxidation state of the protein.  CA125 is acknowledged as the "best validated and most widely assayed biomarker" of ovarian cancer, and the "gold standard" against which other biomarkers are measured.  Understanding CA125 and its potential for simultaneous use with other biomarkers is an important step toward more reliable and earlier detection of ovarian cancer.

Science from Facts on File

Facts on File offers the database Science Online (not to be confused with Science, the premier journal from AAAS), which includes far more than simply a handy compilation of facts.  The Science in the News feature is well worth a daily visit, bringing together news articles from around the world in easy-to-browse subject categories.  A recent post in the "natural science" category, dated July 30, 2010, is of regional interest: New Research Examines Midwest Earthquakes. Melting ice sheets, rapid erosion from the Mississippi River, and stored stress from ancient mountain building in the Appalachians and Rocky Mountains once combined to produce mighty earthquakes in the middle of the country, where fault stress is longer a major concern.
