Uthium
Uthium is a non-existant metal found in search engine returns.
Search engines such as Google will return several hundred entries on
a search for Uthium. Most of the entries will show a strong medical or scientific context. In many cases the word is mixed in with references to Lithium. Attempts to examine the documents are frustrated by many of the original articles being in archives that take a fee to open. Almost all of the articles are pdf files [1] or images of books [2].
When examples are found that will open, the search mechanisms within
the access find and highlight the word Uthium, but examination of the document shows the human eye that entries are the word Lithium or LITHIUM with the Li or LI crowded to touching. Therefore, Uthium rather than being a useful product is an artifact of scanning by the original source or, in some cases perhaps, in the search engine attempting to do OCR on an image of a document.
