A scientific abstract summarizes your research paper or article in a concise, clearly written way that informs readers about the article's content. Researchers use abstracts to determine whether a paper is relevant to their work and/or decide which papers to acquire and read. For academic conferences, participants only receive copies of the abstracts in proceedings. When readers search through electronic databases for articles, the abstract is usually the sole part of the paper that they see without cost. Typically 200-250 words, a scientific abstract consists of five key parts: title and author information, background, methods, results, and conclusions. 
In the case of Dr Alfred Steinschneider, two decades and tens of millions of research dollars were lost trying to find the elusive link between infant sleep apnea, which Steinschneider said he had observed and recorded in his laboratory, and sudden infant death syndrome (SIDS), of which he stated it was a precursor. The cover was blown in 1994, 22 years after Steinschneider's 1972 Pediatrics paper claiming such an association,  when Waneta Hoyt , the mother of the patients in the paper, was arrested, indicted and convicted on 5 counts of second-degree murder for the smothering deaths of her five children.  While that in itself was bad enough, the paper, presumably written as an attempt to save infants' lives, ironically was ultimately used as a defense by parents suspected in multiple deaths of their own children in cases of Münchausen syndrome by proxy . The 1972 Pediatrics paper was cited in 404 papers in the interim and is still listed on Pubmed without comment. 
Plagiarism (use of others words, ideas, images, etc. without citation) is not to be tolerated and can be easily avoided by adequately referencing any and all information you use from other sources. In the strictest sense, plagiarism is representation of the work of others as being your work. Paraphrasing other's words too closely may be construed as plagiarism in some circumstances. In journal style papers there is virtually no circumstance in which the findings of someone else cannot be expressed in your own words with a proper citation of the source. Refer to: The Bates College Statement On Plagiarism and a Guide to Source Acknowledgment .) If you are unclear about what constitutes plagiarism, please confer with your instructor.
