Everard Home
Sir Everard Home, 1st Baronet, FRS (6 May 1756, in Kingston upon Hull – 31 August 1832, in London) was a British surgeon. Life Home was born in Kingston-upon-Hull and educated at Westminster School. He gained a scholarship to Trinity College, Cambridge, but decided instead to become a pupil of his brother-in-law, John Hunter, at St George's Hospital. Hunter had married his sister, the poet and socialite Anne Home, in July 1771. He assisted Hunter in many of his anatomical investigations, and in the autumn of 1776 he partly described Hunter's collection. There is also considerable evidence that Home plagiarized Hunter's work, sometimes directly, sometimes indirectly; he also systematically destroyed his brother-in-law's papers in order to hide evidence of this plagiarism. It seems likely that the fire (in Home's apartments at Chelsea Hospital) which destroyed the Hunterian manuscripts in Home's possession also destroyed a precious collection of 26 microscopes originally ma ...

Sir Everard Home 1756–1832
''Sir'' is a formal honorific address in English for men, derived from Sire in the High Middle Ages. Both are derived from the old French "" (Lord), brought to England by the French-speaking Normans, and which now exist in French only as part of "", with the equivalent "My Lord" in English. Traditionally, as governed by law and custom, Sir is used for men who are knights and belong to certain orders of chivalry, as well as later applied to baronets and other offices. As the female equivalent for knighthood is damehood, the ''suo jure'' female equivalent term is typically Dame. The wife of a knight or baronet tends to be addressed as Lady, although a few exceptions and interchanges of these uses exist. Additionally, since the late modern period, Sir has been used as a respectful way to address a man of superior social status or military rank. Equivalent terms of address for women are Madam (shortened to Ma'am), in addition to social honorifics such as Mrs, Ms, or Miss. Etym ...

American Academy Of Arts And Sciences
The American Academy of Arts and Sciences (The Academy) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a nominating petition, review, and election process. The academy's quarterly journal, '' Dædalus'', is published by the MIT Press on behalf of the academy, and has been open-access since January 2021. The academy also conducts multidisciplinary public policy research. Laurie L. Patton has served as President of the Academy since January 2025. History The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people."

Thomas Bell (zoologist)
Thomas Hornsey Bell FRS FLS (11 October 1792 – 13 March 1880) was an English zoologist Zoology ( , ) is the scientific study of animals. Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. Zoology is one ..., Dental surgery, dental surgeon and writer, born in Poole, Dorset, England. Career Bell, like his mother Susan, took a keen interest in natural history which his mother also encouraged in his younger cousin Philip Henry Gosse. Bell left Poole in 1813 for his training as a dental surgeon in London. He is listed in 1817 as having an address at number 17 Fenchurch Street, and as being a committee member of the newly formed London Peace Society. By 1819 his address is given as 18 Bucklersbury, also in the city of London. He combined two careers, becoming Professor of Zoology at King's College London in 1836 (on the strength of amateur research) ...

Kinixys Homeana
Home's hinge-back tortoise (''Kinixys homeana'') is a species of tortoise in the family Testudinidae. The species is endemic to Africa. Etymology The specific name, ''homeana'', is in honor of English surgeon and naturalist Everard Home. Geographic range ''K. homeana'' is found in Benin, Cameroon, Democratic Republic of the Congo, Equatorial Guinea, Gabon, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, and possibly Togo. Habitat The natural habitats of Home's hinge-back tortoise are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and plantations. Ecology and life history Home's hinge-back tortoise is naturally attracted to red or pink flowers. It prefers low light and often moves in early morning or dusk, preferring to stay hidden the rest of the day. Diet In captivity the diet of ''K. homeana'' may include, banana, guava, watermelon, black mushrooms, cooked sweet potato, cooked potato, and cooked or raw squash, and sources of animal protein suc ...

Melanin
Melanin (; ) is a family of biomolecules organized as oligomers or polymers, which among other functions provide the pigments of many organisms. Melanin pigments are produced in a specialized group of cells known as melanocytes. There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. Melanin is produced through a multistage chemical process known as melanogenesis, where the oxidation of the amino acid tyrosine is followed by polymerization. Pheomelanin is a cysteinated form containing poly benzothiazine portions that are largely responsible for the red or yellow tint given to some skin or hair colors. Neuromelanin is found in the brain. Research has been undertaken to investigate its efficacy in treating neurodegenerative disorders such as Parkinson's. Allomelanin and pyomelanin are two types of nitrogen-free melanin. The phenotypic color variation observed in the epidermis and hair of mammals is primarily determi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ann Moyal
Ann Veronica Helen Moyal (née Hurley, formerly Cousins and Mozley; 23 February 1926 – 21 July 2019) was an Australian historian known for her work in the history of science. She held academic positions at the Australian National University (ANU), New South Wales Institute of Technology, and Griffith University, and later worked as an independent scholar.

Ovoviviparity
Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop inside eggs that remain in the mother's body until they are ready to hatch. The young of some ovoviviparous amphibians, such as '' Limnonectes larvaepartus'', are born as larvae, and undergo further metamorphosis outside the body of the mother. Members of genera '' Nectophrynoides'' and '' Eleutherodactylus'' bear froglets, not only the hatching, but all the most conspicuous metamorphosis, being completed inside the body of the mother before birth. Among insects that depend on opportunistic exploitation of transient food sources, such as many Sarcophagidae and other carrion flies, and species such as many Calliphoridae, that rely on fresh dung, and parasitoids such as tachinid flies that depend on entering the host as soon as possible, the embryos ...

Viviparity
In animals, viviparity is development of the embryo inside the body of the mother, with the maternal circulation providing for the metabolic needs of the embryo's development, until the mother gives birth to a fully or partially developed juvenile that is at least metabolically independent. This is opposed to oviparity, where the embryos develop independently outside the mother in eggs until they are developed enough to break out as hatchlings; and ovoviviparity, where the embryos are developed in eggs that remain carried inside the mother's body until the hatchlings emerge from the mother as juveniles, similar to a live birth. Etymology The term "viviparity" and its adjective form "viviparous" both derive from the Latin ''vivus'', meaning "living"; and ''pario'', meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovulipari ...

Mary Anning
Mary Anning (21 May 1799 – 9 March 1847) was an English fossil collector, fossil trade, dealer, and palaeontologist. She became known internationally for her discoveries in Jurassic marine fossil beds in the cliffs along the English Channel at Lyme Regis in the county of Dorset, South West England, Southwest England. Anning's findings contributed to changes in scientific thinking about prehistoric life and the Historical geology, history of the Earth. Anning searched for fossils in the area's Blue Lias and Charmouth Mudstone Formation, Charmouth Mudstone cliffs, particularly during the winter months when landslides exposed new fossils that had to be collected quickly before they were lost to the sea. Her discoveries included the first correctly identified ichthyosaur skeleton when she was twelve years old; the first two nearly complete plesiosaur skeletons; the first pterosaur skeleton located outside Germany; and fish fossils. Her observations played a key role in the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
