The Annals of Improbable Research (AIR) is a bi-monthly magazine devoted to scientific humor, in the form of a satirical take on the standard academic journal. AIR, published six times a year since 1995, usually showcases at least one piece of scientific research being done on a strange or unexpected topic, but most of their articles concern real or fictional absurd experiments, such as a comparison of apples and oranges using infrared spectroscopy. Other features include such things as ratings of the cafeterias at scientific institutes, fake classified and advertisements for a medical plan called HMO-NO, and a very odd letters page.

Occasional AIR articles are factual and illuminating, if a bit offbeat. For example, in 2003 researcher-documentary producer Nick T. Spark wrote about the background and history of Murphy's Law in a four-part article, "Why Everything You know About Murphy's Law is Wrong".[1] It was revised, expanded and later published in June 2006 as the book A History of Murphy's Law.

AIR awards the annual science Ig Nobel Prizes, for ten achievements that "first make people laugh, and then make them think". AIR also runs the Luxuriant Flowing Hair Club for Scientists [2].
