Am I pregnant? The answer to this age-old question once demanded a combination of guesswork, intuition, and time. In 1978, however, the long wait to know for sure became a thing of the past. Trumpeted by advertisements as “a private little revolution,” the first home pregnancy tests started appearing on drug store shelves that year. A quarter of a century later, innovations promise to make even the telltale thin blue line obsolete. This web site looks at the history of the home pregnancy test—one of the most ubiquitous home healthcare products in America—and examines its place in our culture.

The home pregnancy test works by identifying the presence of the “pregnancy hormone,” human chorionic gonadotropin (hCG), in urine. Research that led to a sensitive, accurate test for hCG was done by scientists in the Reproductive Research Branch of the National Institute of Child Health and Human Development at NIH.

This page is dedicated to the life and work of the Argentinian anthropologist and paleontologist Florentino Ameghino. Alhough he has become most widely known through his anthropological work, I will focus primarily on the work Ameghino has performed on Phorusrhacids, a group of flightless carnivorous birds from the Cenozoic.

The purpose of the GATE experiment was to understand the tropical atmosphere and its role in the global circulation of the atmosphere. It was the first major experiment of the Global Atmospheric Research program, whose goal was to understand the predictability of the atmosphere and extend the time range of daily weather forecasts to over two weeks.

The American Museum of the Moving Image is dedicated to educating the public about the art, history, technique, and technology of film, television, and digital media and to examining their impact on culture and society.

It achieves these goals by maintaining the nation's largest permanent collection of moving image artifacts and by offering exhibitions, film screenings, lectures, seminars, and other education programs.

The online presentation of The Wilbur and Orville Wright Papers at the Library of Congress, comprising about 10,121 library items or approximately 49,084 digital images, documents the lives of Wilbur and Orville Wright and highlights their pioneering work which led to the world's first powered, controlled and sustained flight. Included in the collection are correspondence, diaries and notebooks, scrapbooks, drawings, printed matter, and other documents, as well as the Wrights' collection of glass-plate photographic negatives. The Wright Brothers' letters to aviation pioneer and mentor Octave Chanute, from the Octave Chanute Papers, were also selected for this online collection. The Wright Papers span the years 1881 to 1952 but largely cover 1900 to 1940. This online presentation includes the famous glass-plate negative of the "First Flight" at Kitty Hawk on December 17, 1903, as well as diaries and letters in which Wilbur and Orville Wright recount their work that led to that day.

The reader will, I hope, agree that the "almost-antiseptic" washing machines of today don't have nearly the charm nor the character, albeit hazardous character, of those our grandmothers used. Our presentation herein is focused on the elegant washing machines which were powered either with gasoline engines or electric motors and were in use from 1900-1935. In 1920 there were over 1300 companies producing washers, and it is feasible here to show only a sampling of the myriad designs and shapes produced. Selected for illustration, are about 5% of the machines in my "hobby museum" located in Eaton, Colorado. Indeed, there is a lot more to see.

This site provides background information on clean air legislation and related efforts to enforce a reduction of pollutants in our atmosphere. It also serves as an introduction to a threaded discussion group on this subject that is being conducted by the American Meteorological Society.
