MedlinePlus: Worth Its Weight in Gold

MedlinePlus is a free health information resource from the United States’ National Library of Medicine. This post is not a comprehensive review of the entire site, but will give a general overview and highlight some of my favorite areas.

It contains links to over 975 medical topics, including links to the A.D.A.M. medical encyclopedia and the Merriam-Webster medical dictionary. The statistics page of the website reports that there is Information from over 1,000 organizations containing over 35,000 links to authoritative health information. Continue reading

Locating Nuclear Energy Data using U.S. Energy Information Administration


Nuclear energy is the energy contained in the nucleus of an atom. When the atoms are broken apart in the fission process, the energy released can be used to generate electricity. The most common element used in nuclear fission is uranium.

The U.S. Energy Information Administration (EIA) is a one-stop shop for all data and statistics on nuclear power. Topics covered include nuclear operable units, electricity generation, storage of radioactive waste, and state of operating nuclear power plants. While the focus of this data is on nuclear power in the United States, there is also data provided for yearly international nuclear electricity generation.

Scholarly Communication and the History of Flight

Letter to the Smithsonian Institution, 1899
Letter to the Smithsonian Institution, 1899

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.

Understanding BLAST and Improving Your Search


BLAST, the Basic Local Alignment Sequence Tool ( 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.
