Roy John Britten (1919-2012) Abhinav Mishra Roy John Britten studied DNA sequences in the US in the second half of the twentieth century, and he helped discover repetitive elements in DNA sequences. Additionally, Britten helped propose models and concepts of gene regulatory networks. Britten studied the organization of repetitive elements and, analyzing data from the Human Genome Project, he found that the repetitive elements in DNA segments do not code for proteins, enzymes, or cellular parts. Britten hypothesized that repetitive elements helped cause cells to 2014-10-24 4 Jul 2018 - 4:40:59am

Pope Pius XI (1857-1939) Katherine Brind'Amour Pope Pius XI, born Ambrogio Damiano Achille Ratti, was born to the wealthy owner of a silk factory on 31 May 1857 in Desio, Italy. He was ordained to the priesthood at the age of eighteen, at which time he began a long life devoted to study, peacekeeping, and the betterment of societies around the world. Pius XI is noted here for his contribution to the Roman Catholic Church's early twentieth century approach to issues regarding contraception and abortion, which was presented in his December 1930 encyclical "Casti Connubii." 2007-11-11 4 Jul 2018 - 4:40:59am
James Marion Sims (1813-1883) Amanda Andrei James Marion Sims developed a surgical cure for ruptures of the wall separating the bladder from the vagina during labor, ruptures called vesico-vaginal fistulas, and he developed techniques and tools used to improve reproductive examinations and health care for women in the US during the nineteenth century. Sims's lateral examination position allowed doctors to better see the vaginal cavity, and his speculum, a spoon-like object used for increased view into the vagina, helped to make gynecological examinations more thorough. 2013-04-08 4 Jul 2018 - 4:40:59am
Arthur William Galston (1920–2008) Cecilia Chou Arthur W. Galston studied plant hormones in the United States during the late-twentieth century. His dissertation on the flowering process of soybean plants led others to develop Agent Orange, the most widely employed herbicide during the Vietnam War, used to defoliate forests and eliminate enemy cover and food sources. Galston protested the spraying of those defoliants in Vietnam, as they could be harmful to humans, animals, and the environment. 2017-04-27 4 Jul 2018 - 4:40:59am

Alec John Jeffreys (1950–) Corey Harbison Alec John Jeffreys created a process called DNA fingerprinting in the UK during the twentieth century. For DNA fingerprinting, technicians identify a person as the source of a biological sample by comparing the genetic information contained in the person's DNA to the DNA contained in the sample. Jeffreys developed the technique in the 1980s while at the University of Leicester in Leicester, UK. Jeffreys's technique had immediate applications. In forensic science, DNA fingerprinting enabled police to identify suspects of crimes based on their genetic identities. 2017-06-15 4 Jul 2018 - 4:40:59am
Carl Richard Moore (1892-1955) Mary Drago Carl Richard Moore was a professor and researcher at the University of Chicago in Chicago, Illinois who studied sex hormones in animals from 1916 until his death in 1955. Moore focused on the role of hormones on sex differentiation in offspring, the optimal conditions for sperm production, and the effects of vasectomy or testicular implants on male sex hormone production. Moore's experiments to create hermaphrodites in the laboratory contributed to the theory of a feedback loop between the pituitary and fetal gonadal hormones to control sex differentiation. 2014-02-18 4 Jul 2018 - 4:40:59am

Mary-Claire King (1946– ) Meilin Zhu Mary-Claire King studied genetics in the US in the twenty-first century. King identified two genes associated with the occurrence of breast cancer, breast cancer 1 (BRCA1) and breast cancer 2 (BRCA2). King showed that mutated BRCA1 and BRCA2 genes cause two types of reproductive cancer, breast and ovarian cancer. Because of King’s discovery, doctors can screen women for the inheritance of mutated BRCA1 and BRCA2 genes to evaluate their risks for breast and ovarian cancer. 2017-08-23 4 Jul 2018 - 4:40:59am

Restell was tried numerous times for carrying out abortions. 2017-08-23 4 Jul 2018 - 4:40:59am
Walter Stanborough Sutton (1877-1916) Abhinav Mishra Walter Stanborough Sutton studied grasshoppers and connected the phenomena of meiosis, segregation, and independent assortment with the chromosomal theory of inheritance in the early twentieth century in the US. Sutton researched chromosomes, then called inheritance mechanisms. He confirmed a theory of Wilhelm Roux, who studied embryos in Breslau, Germany, in the late 1880s, who had argued that chromosomes and heredity were linked. Theodor Boveri, working in Munich, Germany, independently reached similar conclusions about heredity as Sutton. 2014-06-27 4 Jul 2018 - 4:40:59am
Albrecht von Haller (1708-1777) Cera R. Lawrence Victor Albrecht von Haller was an 18th century scientist who did extensive work in the life sciences, including anatomy and physiology, botany, and developmental biology. His embryological work consisted of experiments in understanding the process of generation, and led him to adopt the model of preformationism called ovism (the idea that the new individual exists within the maternal egg prior to conception). Haller was born in Bern, Switzerland, on 16 October, 1708. His mother was Anna Maria Engel, and his father was Niklaus Emanuel Haller. 2008-09-22 4 Jul 2018 - 4:40:59am
