Powered, controlled flight is a scientific and engineering achievement rich with examples of scholarly communication. Background sources provide a foundation. Correspondence provides insight into challenges and developments in a field. Experimental findings shared via professional meetings and journal articles encourage wider discussion and further exploration. Scholarly conversations between the Wright brothers and Octave Chanute preserved in digital collections at the Library of Congress provide a rich exemplar for students learning about scholarly communication.

BLAST, the Basic Local Alignment Sequence Tool (http://blast.ncbi.nlm.nih.gov/Blast.cgi) is a data mining tool provided by the National Center for Biotechnology Information (NCBI). It allows users to input a nucleic acid or protein sequence and search against millions of other sequences in the database to identify those based on similarity and not identity. Ideally, search results will hopefully identify known sequences and provide insight into the possible identity and function of the sequence of interest.
Are you still looking for a reliable federated search tool that goes beyond the run-of-the-mill results? Do you miss searching Scirus by Elsevier? WorldWideScience.org might be a worthwhile alternative to explore. Developed and maintained by the U.S. Department of Energy Office of Scientific and Technical Information (OSTI), WorldWideScience.org has partnerships with many national and international science portals and one can search the interface in ten different languages: Arabic, Chinese, English, French, German, Japanese, Korean, Portuguese, Russian, and Spanish. Searching multiple sources, WorldWideScience.org displays results based on their relevance order. Continue reading
Searching for information on complex organic molecules can be an onerous task. Many organic compounds have both common and systematic names. For example, caffeine can also be known as guaranine, methyltheobromine, 1,3,7-trimethylxanthine, theine, or 1,3,7-trimethylpurine-2,6-dione. Researchers performing comprehensive literature searches will be interested in research involving not only a specific compound but also similar compounds or other molecules containing the same substructure. Searching on a specific systematic name may inadvertently omit stereoisomers, tautomers, molecules containing the same substructure of interest, or molecules differing by the substitution of as little as one atom. Conceiving of all appropriate synonyms for a name-based search would be a Herculean task for both an organic chemist and a science librarian.
ARCTIC MATTERS DAY is January 14th, 2016 so declares the National Research Council of the National Academies
They have published a lavishly illustrated 32-page booklet explaining, showing that changes in the Arctic affect the whole globe. It was announced in the weekly news from the Academies, WhatsNew@National-Academies.org in their Friday alert on January 8, 2016. Incidentally, one may subscribe to the newsletter by writing to: firstname.lastname@example.org
What are standards?
Standards are guidelines or rules for products, processes, test methods, or materials.
These are created to produce a level of uniformity, interchangeability, reliability, or means of comparison.
Standards influence daily life including our method of communication, the products we use, how we travel to work, and what we eat.
Searching patent information is a challenge for most librarians on a good day whether it is on Google Patents, ESPACEnet, or the USPTO. A rather new site, Lens, has entered the landscape. Lens is a self-described “open public resource for innovation cartography.” Aside from the rather quirky byline on the site’s home page, this open resource searches “nearly all of the patent documents in the world as open, annotatable digital public goods that are integrated with scholarly and technical literature along with regulatory and business data” (https://www.lens.org/about/what/).
What is the DOE Data Explorer?
To gain familiarity with real examples of research data take a look at the DOE Data Explorer. This resource provides a place to discover a huge variety of scientific research data generated from projects funded wholly or in part by the US Department of Energy. Continue reading
What are microstructures?
A microstructure is the small-scale structure of a material. Microstructures can only be viewed using at 25x magnification. Microstructures can have an influence on the physical properties of a material such as corrosion, ductility, strength, and toughness; and are useful when analyzing ceramics, composites, polymers, and metals.
