Barbara McClintock
Barbara McClintock (June 16, 1902 – September 2, 1992) was an American scientist and cytogeneticist who was awarded the 1983 Nobel Prize in Physiology or Medicine. McClintock received her PhD in botany from Cornell University in 1927. There she started her career as the leader of the development of maize cytogenetics, the focus of her research for the rest of her life. From the late 1920s, McClintock studied chromosomes and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of those ideas was the notion of genetic recombination by crossing-over during meiosis—a mechanism by which chromosomes exchange information. She produced the first genetic map for maize, linking regions of the chromosome to physical traits. She demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of gen ...

CRISPR Gene Editing
CRISPR gene editing (pronounced "crisper") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial CRISPR-Cas9 antiviral defense system. By delivering the Cas9 nuclease complexed with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added ''in vivo''. The technique is considered highly significant in biotechnology and medicine as it enables editing genomes ''in vivo'' very precisely, cheaply, and easily. It can be used in the creation of new medicines, agricultural products, and genetically modified organisms, or as a means of controlling pathogens and pests. It also has possibilities in the treatment of inherited genetic diseases as well as diseases arising from somatic mutations such as cancer. However, its use in human germline genetic modification is highly controve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Francis Crick
Francis Harry Compton Crick (8 June 1916 – 28 July 2004) was an English molecular biologist, biophysicist, and neuroscientist. He, James Watson, Rosalind Franklin, and Maurice Wilkins played crucial roles in deciphering the helical structure of the DNA molecule. Crick and Watson's paper in ''Nature'' in 1953 laid the groundwork for understanding DNA structure and functions. Together with Maurice Wilkins, they were jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material". Crick was an important theoretical molecular biologist and played a crucial role in research related to revealing the helical structure of DNA. He is widely known for the use of the term " central dogma" to summarise the idea that once information is transferred from nucleic acids (DNA or RNA) to proteins, it cannot flow back to nucleic acids. In other words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Study
The nature study movement (alternatively, Nature Study or nature-study) was a popular education movement that originated in the United States and spread throughout the English-speaking world in the late 19th and early 20th centuries. Nature study attempted to reconcile scientific investigation with spiritual, personal experiences gained from interaction with the natural world. Led by progressive educators and naturalists such as Anna Botsford Comstock, Liberty Hyde Bailey, Louis Agassiz, William Gould Vinal, and Wilbur S. Jackman, nature study changed the way science was taught in schools by emphasizing learning from tangible objects, something that was embodied by the movement's mantra: "study nature, not books". The movement popularized scientific study outside of the classroom as well, and has proven highly influential for figures involved in the modern environmental movement, such as Aldo Leopold and Rachel Carson. Background By the mid-19th century, a growing concern fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illustrator
An illustrator is an artist who specializes in enhancing writing or elucidating concepts by providing a visual representation that corresponds to the content of the associated text or idea. The illustration may be intended to clarify complicated concepts or objects that are difficult to describe textually, which is the reason illustrations are often found in children's books. Illustration is the art of making images that work with something and add to it without needing direct attention and without distracting from what they illustrate. The other thing is the focus of the attention, and the illustration's role is to add personality and character without competing with that other thing. Illustrations have been used in advertisements, architectural rendering, greeting cards, posters, books, graphic novels, storyboards, business, technical communications, magazines, shirts, video games, tutorials, and newspapers. A cartoon illustration can add humor to stories or essays. Tech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anna Botsford Comstock
Anna Botsford Comstock (September 1, 1854 – August 24, 1930) was an acclaimed author, illustrator, and educator of natural studies. The first female professor at Cornell University, her over 900-page work, ''The Handbook of Nature Study'' (1911), is now in its 24th edition. Comstock was an American artist and wood engraver known for illustrating entomological text books with her her husband, John Henry Comstock including their first joint effort, ''The Manual for the Study of Insects'' (1885). Comstock worked with Liberty Hyde Bailey, John Walton Spencer, Alice McCloskey, Julia Rogers, and Ada Georgia as part of the department of Nature Study at Cornell University. Together they wrote nature study curricula to develop a curiosity for, and education about, the surrounding natural world. Comstock also was a proponent for conservationism by instilling a love and appreciation of the natural world around us. Early life and education Anna Botsford Comstock was born in a log house iOtt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julia Warner Snow
Julia Warner Snow (August 30, 1863 – October 24, 1927) was an American botanist and was known in the scientific community for her work as a systematic phycologist. Snow was born in La Salle, Illinois, the third child of Norman G. Snow and Charlotte D. (née Warner). At the age of sixteen she left La Salle to enter Hungerford Collegiate Institute, Adams, New York. After graduating in 1880, she returned home to live with her parents, then in 1884 matriculated to Cornell University in Ithaca, New York.
