Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert William Briggs
Robert Briggs (December 10, 1911 — March 4, 1983) was a scientist who, in 1952, together with Thomas Joseph King, cloned a frog by nuclear transfer of embryonic cells. The same technique, using somatic cells, was later used to create Dolly the Sheep. Their experiment was the first successful nuclear transplantation performed in metazoans. He was a scientist at the Institute for Cancer Research of the Lankenau Hospital Research Institute (now known as the Lankenau Institute for Medical Research) when the work was conducted. Background Upon the death of his mother when he was two years old, Briggs was raised by his grandparents in Epping, New Hampshire. Inspired by a high school science teacher, Briggs became interested in the biological sciences. However, he began Boston University in the business school, concerned with earning a living during the Depression. Business courses couldn’t maintain his interest and he turned to the sciences. He graduated from Boston University in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oocyte
An oocyte (, ), oöcyte, or ovocyte is a female gametocyte or germ cell involved in reproduction. In other words, it is an immature ovum, or egg cell. An oocyte is produced in a female fetus in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis, forming oogonia. During oogenesis, the oogonia become primary oocytes. An oocyte is a form of genetic material that can be collected for cryoconservation. Formation The formation of an oocyte is called oocytogenesis, which is a part of oogenesis. Oogenesis results in the formation of both primary oocytes during fetal period, and of secondary oocytes after it as part of ovulation. Characteristics Cytoplasm Oocytes are rich in cytoplasm, which contains yolk granules to nourish the cell early in development. Nucleus During the primary oocyte stage of oogenesis, the nucleus is called a germinal vesicle. The only normal human type of secondary oocyte has t ...

Cloning
Cloning is the process of producing individual organisms with identical or virtually identical DNA, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction. In the field of biotechnology, cloning is the process of creating cloned organisms (copies) of Cell (biology), cells and of DNA fragments (molecular cloning). Etymology Coined by Herbert J. Webber, the term clone derives from the Ancient Greek word (), ''twig'', which is the process whereby a new plant is created from a twig. In botany, the term ''lusus'' was used. In horticulture, the spelling ''clon'' was used until the early twentieth century; the final ''e'' came into use to indicate the vowel is a "long o" instead of a "short o". Since the term entered the popular lexicon in a more general context, the spelling ''clone'' has been used exclusively. Natural cloning Cloning is a natural form of reproduction that has allowed life forms to spread for hundreds of millio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lankenau Institute For Medical Research
Lankenau Institute for Medical Research (LIMR), founded in 1927, is a nonprofit, biomedical research institute located on the campus of Lankenau Medical Center in Wynnewood, Pennsylvania, serving as the research division of the Main Line Health System in suburban Philadelphia. LIMR focuses on studies of cancer, cardiovascular, autoimmune, gastrointestinal and other diseases. It houses a center for population health research. History LIMR was one of the first U.S. research institutes to focus on cancer when it was founded in 1927. It was formerly known as the Lankenau Hospital Research Institute (LHRI) until 1980 and the Lankenau Medical Research Center (LMRC) from 1981-1999. Starting in 1941, LHRI also housed the Institute for Cancer Research (ICR), until the ICR was merged with the former American Oncology Hospital to create Fox Chase Cancer Center in 1974. LHRI researcher David Hungerford is credited with the discovery of the first genetic abnormality in cancer, called the Ph ...

Grand Prix Charles-Leopold Mayer
The Grand Prix Charles-Léopold Mayer (Charles-Léopold Mayer Prize) is awarded annually by the Académie des Sciences (French Academy of Sciences) de l'Institut de France (the French Institute) to researchers who have performed outstanding work in the biological sciences; especially in the areas of cell or molecular biology. Citizens or residents of any nation are eligible for the prize, but it is never awarded to individuals of the same nation two years in a row, nor is the prize ever presented to scholars who are more than 65 years of age. Between the first presentation of the award in 1961 and the year 2009, there have been more than 60 laureates, eleven of whom subsequently received the Nobel Prize in medicine, physiology, or chemistry. The prize is named after French biochemist Charles Léopold Mayer.

Académie Des Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its British ...
