Mildred Cohn
Mildred Cohn (July 12, 1913 – October 12, 2009) was an American biochemist who furthered understanding of biochemistry, biochemical processes through her study of chemical reactions within animal cell (biology), cells. She was a pioneer in the use of nuclear magnetic resonance for studying Enzyme catalysis, enzyme reactions, particularly reactions of adenosine triphosphate (ATP). She received the nation's highest science award, the National Medal of Science, in 1982, and was inducted into the National Women's Hall of Fame. Early life Cohn's parents, childhood sweethearts Isidore Cohn and Bertha Klein Cohn, were Jewish. Her father was a rabbi. They left Russia for the United States around 1907. Mildred Cohn was born July 12, 1913, in the Bronx, where her family lived in an apartment. When Mildred was 13, her father moved the family to a Yiddish-speaking cooperative, ''Heim Gesellschaft'', which strongly emphasized education, the arts, social justice, and the preservation o ...

Enzyme Catalysis
Enzyme catalysis is the increase in the rate of a process by an "enzyme", a biological molecule. Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site. Most enzymes are made predominantly of proteins, either a single protein chain or many such chains in a multi-subunit complex. Enzymes often also incorporate non-protein components, such as metal ions or specialized organic molecules known as cofactor (e.g. adenosine triphosphate). Many cofactors are vitamins, and their role as vitamins is directly linked to their use in the catalysis of biological process within metabolism. Catalysis of biochemical reactions in the cell is vital since many but not all metabolically essential reactions have very low rates when uncatalysed. One driver of protein evolution is the optimization of such catalytic activities, although only the most crucial enzymes operate near catalytic ...

Nobel Prize
The Nobel Prizes ( ; ; ) are awards administered by the Nobel Foundation and granted in accordance with the principle of "for the greatest benefit to humankind". The prizes were first awarded in 1901, marking the fifth anniversary of Alfred Nobel, Alfred Nobel's death. The original Nobel Prizes covered five fields: Nobel Prize in Physics, physics, Nobel Prize in Chemistry, chemistry, Nobel Prize in Physiology or Medicine, physiology or medicine, Nobel Prize in Literature, literature, and Nobel Peace Prize, peace, specified in Nobel's will. A sixth prize, the Nobel Memorial Prize in Economic Sciences, Prize in Economic Sciences, was established in 1968 by Sveriges Riksbank (Sweden's central bank) in memory of Alfred Nobel. The Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields.Nobel Prize#Shalev69, Shalev, p. 8. Except in extraordinary circumstances, such as war, all six prizes are given annually. Each recipient, known as a laur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master's Degree
A master's degree (from Latin ) is a postgraduate academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice. A master's degree normally requires previous study at the bachelor's degree, bachelor's level, either as a separate degree or as part of an integrated course. Within the area studied, master's graduates are expected to possess advanced knowledge of a specialized body of theoretical and applied topics; high order skills in analysis [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Heritage Foundation
The Science History Institute is an institution that preserves and promotes understanding of the history of science. Located in Philadelphia, Pennsylvania, it includes a library, museum, archive, research center and conference center. It was founded in 1982 as a joint venture of the American Chemical Society and the University of Pennsylvania, as the Center for the History of Chemistry (CHOC). The American Institute of Chemical Engineers (AIChE) became a co-founder in 1984. It was renamed the Chemical Heritage Foundation (CHF) in 1992, and moved two years later to the institution's current location, 315 Chestnut Street in Old City. On December 1, 2015, CHF merged with the Life Sciences Foundation, creating an organization that covers "the history of the life sciences and biotechnology together with the history of the chemical sciences and engineering." As of February 1, 2018, the organization was renamed the Science History Institute, to reflect its wider range of histori ...

Social Justice
Social justice is justice in relation to the distribution of wealth, opportunities, and privileges within a society where individuals' rights are recognized and protected. In Western and Asian cultures, the concept of social justice has often referred to the process of ensuring that individuals fulfill their societal roles and receive their due from society. In the current movements for social justice, the emphasis has been on the breaking of barriers for social mobility, the creation of safety nets, and economic justice. Social justice assigns rights and duties in the institutions of society, which enables people to receive the basic benefits and burdens of cooperation. The relevant institutions often include taxation, social insurance, public health, public school, public services, labor law and regulation of markets, to ensure distribution of wealth, and equal opportunity. Modernist interpretations that relate justice to a reciprocal relationship to society a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yiddish
Yiddish, historically Judeo-German, is a West Germanic language historically spoken by Ashkenazi Jews. It originated in 9th-century Central Europe, and provided the nascent Ashkenazi community with a vernacular based on High German fused with many elements taken from Hebrew language, Hebrew (notably Mishnaic Hebrew, Mishnaic) and to some extent Aramaic. Most varieties of Yiddish include elements of Slavic languages and the vocabulary contains traces of Romance languages.Aram Yardumian"A Tale of Two Hypotheses: Genetics and the Ethnogenesis of Ashkenazi Jewry".University of Pennsylvania. 2013. Yiddish has traditionally been written using the Hebrew alphabet. Prior to World War II, there were 11–13 million speakers. 85% of the approximately 6 million Jews who were murdered in the Holocaust were Yiddish speakers,Solomon Birnbaum, ''Grammatik der jiddischen Sprache'' (4., erg. Aufl., Hamburg: Buske, 1984), p. 3. leading to a massive decline in the use of the language. Jewish ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rabbi
A rabbi (; ) is a spiritual leader or religious teacher in Judaism. One becomes a rabbi by being ordained by another rabbi—known as ''semikha''—following a course of study of Jewish history and texts such as the Talmud. The basic form of the rabbi developed in the Pharisees, Pharisaic (167 BCE–73 CE) and Talmudic (70–640 CE) eras, when learned teachers assembled to codify Judaism's written and oral laws. The title "rabbi" was first used in the first century CE. In more recent centuries, the duties of a rabbi became increasingly influenced by the duties of the Clergy, Protestant Christian minister, hence the title "pulpit rabbis." Further, in 19th-century Germany and the United States, rabbinic activities such as sermons, pastoral counseling, and representing the community to the outside all increased in importance. Within the various Jewish denominations, there are different requirements for rabbinic ordination and differences in opinion regarding who is recognized as a ...
