Microbes are recognized for their diverse metabolic activity and ubiquitous presence, unique strategies of survival under extreme conditions, and important impacts on human health and technology. Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point, hundreds of millions of years before dinosaurs roamed the earth.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
