Émile Maupas
François Émile Maupas (2 July 1842 in Vaudry – 18 October 1916 in Algiers) was a French librarian, protozoologist, cytologist, and botanist. Maupas contributed to ideas on the life cycle and reproduction of the ciliates. He founded the idea, known as the Maupasian life cycle, that some protists had a definite death following sexual reproduction, contrary to contemporary ideas on protists being immortal. He also identified the existence of mating types in ciliates. He developed culture techniques for a number of organisms and described the nematode ''Caenorhabditis elegans,'' which has since become a widely used model organism in biological studies. Life and work Maupas was born in Vaudry, to deputy mayor Pierre Augustin and Marie Adèle Geffroy. After studies at the local schools he joined the École des chartes, and from 1867 he worked as an archivist in Cantal. It was here that he developed an interest in natural history and began to study protozoa working in summer at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century French Botanists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

History Of Research On Caenorhabditis Elegans
The nematode worm ''Caenorhabditis elegans'' was first studied in the laboratory by Victor Nigon and Ellsworth Dougherty in the 1940s, but came to prominence after being adopted by Sydney Brenner in 1963 as a model organism for the study of developmental biology using genetics. In 1974, Brenner published the results of his first genetic screen, which isolated hundreds of mutants with morphological and functional phenotypes, such as being uncoordinated. In the 1980s, John Sulston and co-workers identified the lineage of all 959 cells in the adult hermaphrodite, the first genes were cloned, and the physical map began to be constructed. In 1998, the worm became the first multi-cellular organism to have its genome sequenced. Notable research using ''C. elegans'' includes the discoveries of caspases, RNA interference RNA interference (RNAi) is a biological process in which RNA molecules are involved in sequence-specific suppression of gene expression by double-stranded RNA, through ...
