Lewis Wolpert
Lewis Wolpert (19 October 1929 – 28 January 2021) was a South African-born British developmental biologist, author, and broadcaster. Wolpert was best known for his French flag model of embryonic development, where he used the French flag as a visual aid to explain how embryonic cells interpret genetic code for expressing characteristics of living organisms and explaining how signalling between cells early in morphogenesis could be used to inform cells with the same genetic regulatory network of their position and role. He was also an author of several science books including ''Triumph of the Embryo'' (1991), ''Malignant Sadness'' (1999), ''The Evolutionary Origins of Belief'' (2006), and ''How We Live And Why We Die: The Secret Lives of Cells'' (2009). Early life Wolpert was born on 19 October 1929, in Johannesburg to Sarah (née Suzman) and William Wolpert in a South African Jewish family of Lithuanian Jewish origin. His father was a bookshop manager and newsagent. Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commander Of The Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Medal
The Royal Medal, also known as The Queen's Medal and The King's Medal (depending on the gender of the monarch at the time of the award), is a silver-gilt medal, of which three are awarded each year by the Royal Society, two for "the most important contributions to the advancement of natural knowledge" and one for "distinguished contributions in the applied sciences", done within the Commonwealth of Nations. Background The award was created by George IV of the United Kingdom, George IV and awarded first during 1826. Initially there were two medals awarded, both for the most important discovery within the year previous, a time period which was lengthened to five years and then shortened to three. The format was endorsed by William IV of the United Kingdom, William IV and Victoria of the United Kingdom, Victoria, who had the conditions changed during 1837 so that mathematics was a subject for which a Royal Medal could be awarded, albeit only every third year. The conditions were chang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Philosophical Society
The American Philosophical Society (APS), founded in 1743 in Philadelphia, is a scholarly organization that promotes knowledge in the sciences and humanities through research, professional meetings, publications, library resources, and community outreach. Considered the first learned society in the United States, it has about 1,000 elected members, and by April 2020 had had only 5,710 members since its creation. Through research grants, published journals, the American Philosophical Society Museum, an extensive library, and regular meetings, the society supports a variety of disciplines in the humanities and the sciences. Philosophical Hall, now a museum, is just east of Independence Hall in Independence National Historical Park; it was designated a National Historic Landmark in 1965. History The Philosophical Society, as it was originally called, was founded in 1743 by Benjamin Franklin, James Alexander (lawyer), James Alexander, Francis Hopkinson, John Bartram, Philip Syn ...

Developmental Biology
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of Regeneration (biology), regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells in the adult organism. Perspectives The main processes involved in the embryogenesis, embryonic development of animals are: tissue patterning (via regional specification and patterned cellular differentiation, cell differentiation); tissue growth; and tissue morphogenesis. * Regional specification refers to the processes that create the spatial patterns in a ball or sheet of initially similar cells. This generally involves the action of cytoplasmic determinants, located within parts of the fertilized egg, and of inductive signals emitted from signaling centers in the embryo. The early stages of regional specification do not generate functional differentiated cells, but cell populations committed to developing ...

Anatomy
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function (biology), function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic research, basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic scale, macroscopic and microscopic scale, microscopic. Gross anatomy, Macroscopic anatomy, or gross anatomy, is the examination of an ...

Biology
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emeritus Professor
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...

Helen Suzman
Helen Suzman, OMSG, DBE (née Gavronsky; 7 November 1917 – 1 January 2009) was a South African anti-apartheid activist and politician. She represented a series of liberal and centre-left opposition parties during her 36-year tenure in the whites-only, National Party-controlled House of Assembly of South Africa at the height of apartheid. She hosted the meeting that founded the Progressive Party in 1959, and was its only MP in the 160-member House for thirteen years. She was the only member of the South African Parliament to consistently and unequivocally oppose all apartheid legislation. Suzman was instrumental in improving prison conditions for members of the banned African National Congress including Nelson Mandela, despite her reservations about Mandela's revolutionary policies, and was also known for using her parliamentary privilege to evade government censorship and pass information to the media about the worst abuses of apartheid. She was twice nominated for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithuanian Jews
Lithuanian Jews or Litvaks () are Jews with roots in the territory of the former Grand Duchy of Lithuania (covering present-day Lithuania, Belarus, Latvia, the northeastern Suwałki and Białystok regions of Poland, as well as adjacent areas of modern-day Russia and Ukraine). The term is sometimes used to cover all Haredi Jews who follow a " Lithuanian" ( Ashkenazi, non- Hasidic) style of life and learning, whatever their ethnic background. The area where Lithuanian Jews lived is referred to in Yiddish as , hence the Hebrew term (). No other famous Jew is more closely linked to a specifically Lithuanian city than Vilna Gaon (in Yiddish, "the genius of Vilna"). Rabbi Elijah ben Solomon Zalman (1720–1797) to give his rarely used full name, helped make Vilna (modern-day Vilnius) a world center for Talmudic learning. Chaim Grade (1910–1982) was born in Vilna, the city about which he would write. The inter-war Republic of Lithuania was home to a large and influential Jewish ...

South African Jews
The history of the Jews in South Africa began during the period of Portuguese exploration in the early modern era, though a permanent presence was not established until the beginning of Dutch colonisation in the region. During the period of British colonial rule in the 19th century, the Jewish South African community expanded greatly, in part thanks to encouragement from Britain. From 1880 to 1914, the Jewish population in South Africa grew from 4,000 to over 40,000. South African Jews have played an important role in promoting diplomatic and military relations between Israel and South Africa. South Africa's Jewish community has reportedly declined from a possible peak of 120,000 to now between 52,000 and 88,000. Many South African Jews have emigrated to countries in the English-speaking world, such as the United States, Canada, the United Kingdom and Australia, as well as some emigrating to Israel.
