In 2009, Shoukhrat Mitalipov, Masahito Tachibana, and their team of researchers developed the technology of mitochondrial gene replacement therapy to prevent the transmission of a mitochondrial disease from mother to offspring in primates. Mitochondria contain some of the body's genetic material, called mitochondrial DNA. Occasionally, the mitochondrial DNA possesses mutations. Mitalipov and Tachibana, researchers at the Oregon National Primate Research Center in Beaverton, Oregon, developed a technique to remove the nucleus of the mother and place it in a donor oocyte, or immature egg cell, with healthy mitochondria. The resulting offspring contain the genetic material of three separate individuals and do not have the disease. Mitalipov and Tachibana's technology of mitochondrial gene replacement built on decades of research by different scientists and enables researchers to prevent the transmission of human mitochondrial diseases from mother to offspring.

In 1954 Max Delbruck published On the Replication of Desoxyribonucleic Acid (DNA) to question the semi-conservative DNA replication mechanism proposed that James Watson and Francis Crick had proposed in 1953. In his article published in the Proceedings of the National Academy of Sciences, Delbrück offers an alternative DNA replication mechanism, later called dispersive replication. Unlike other articles before it, On the Replication presents ways to experimentally test different DNA replication theories. The article sparked a debate in the 1950s over how DNA replicated, which culminated in 1957 and 1958 with the Meselson-Stahl experiment supporting semi-conservative DNA replication as suggested by Watson and Crick. On the Replication played a major role in the study of DNA in the 1950s, a period of time during which scientists gained a better understanding of DNA as a whole and its role in genetic inheritance.

In the 1949 article “Revival of Spermatozoa after Dehydration and Vitrification at Low Temperatures,” researchers Christopher Polge, Audrey Ursula Smith, and Alan Sterling Parkes demonstrated that glycerol prevents cells from dying while being frozen. Polge and his colleagues discussed several procedures in which they had treated sperm cells from various species with glycerol, froze those cells, and then observed the physiological effects that freezing had on the treated sperm. The researchers concluded that glycerol safely preserves sperm samples from a variety of species. Polge, Smith, and Parkes’s 1949 article detailed one of the first successful uses of a chemical medium to preserve viable cells in a frozen state, a process that eventually enabled the first vertebrate embryo to be successfully conceived using frozen sperm.

In 1949, Priscilla White published Pregnancy Complicating Diabetes, which described the results and implications of a fifteen-year study about pregnant diabetic women. Published in the American Journal of Medicine, the article details possible causes of and ways to prevent the high fetal mortality rate associated with pregnant diabetic women. Diabetes is a disease in which the body's ability to produce or respond to the hormone insulin is impaired, and it can be particularly dangerous during pregnancies. In her article, White reported that prematurely delivering infants for diabetic pregnant women reduces infant and maternal mortality rates. Pregnancy Complicating Diabetes helped make premature delivery of infants the standard of care for diabetic pregnant women, and it has contributed to the increased survival rate of infants born from diabetic mothers from less than fifty percent in the 1940s to over ninety percent in 2017.

What Every Girl Should Know was published in 1916 in New York City, New York, as a compilation of articles written by Margaret Sanger from 1912 to 1913. The original articles appeared in the newspaper New York Call, under the tile “What Every Girl Should Know.” The articles, which are organized into chapters and individual parts in the book, describe sex education, human reproduction, and sexually transmitted infections. Sanger, a nurse and social activist, published What Every Girl Should Know during a time in which US federal and state obscenity laws regulated the circulation of literature related to sex. What Every Girl Should Know flouted those laws, helping people to learn about sex education and reproductive health in the US during the early twentieth century.

What Every Mother Should Know was published in 1914 in New York City, New York, as a compilation of newspaper articles written by Margaret Sanger in 1911. The series of articles informed parents about how to teach their children about reproduction and it appeared in the newspaper New York Call. In 1911, the newspaper series was published as a book, with several subsequent editions appearing later. In What Every Mother Should Know, Sanger emphasizes starting education on reproduction early and honestly answering children’s questions. The book acted as a resource for parents and urged readers to be less fearful of approaching the topic with their children. What Every Mother Should Know provided information to the public about sex education and reproductive health, which was scarce during the early twentieth century.

In 1984, Dante Cicchetti published “The Emergence of Developmental Psychopathology,” an article in which he argued that the previously amorphous study of developmental psychopathology was emerging as a unified discipline. According to Cicchetti, developmental psychopathology describes an interdisciplinary field that studies abnormalities in psychological function that can arise during human development. Such studies include research about the effects that traumatic experiences may have on the development of psychological disorders and about what behaviors are considered normal or abnormal at different ages. In the article, Cicchetti reports about the origins of developmental psychopathology, why it emerged as its own discipline, and why researchers should study it. In addition to recognizing the field of developmental psychopathology, the article informed later research about preventing and treating the harmful psychological effects of early traumatic events.

In 2013, George Church and his colleagues at Harvard University in Cambridge, Massachusetts published RNA-Guided Human Genome Engineering via Cas 9, in which they detailed their use of RNA-guided Cas 9 to genetically modify genes in human cells. Researchers use RNA-guided Cas 9 technology to modify the genetic information of organisms, DNA, by targeting specific sequences of DNA and subsequently replacing those targeted sequences with different DNA sequences. Church and his team used RNA-guided Cas 9 technology to edit the genetic information in human cells. Church and his colleagues also created a database that identified 190,000 unique guide RNAs for targeting almost half of the human genome that codes for proteins. In RNA-Guided Human Genome Engineering via Cas 9, the authors demonstrated that RNA-guided Cas 9 was a robust and simple tool for genetic engineering, which has enabled scientists to more easily manipulate genomes for the study of biological processes and genetic diseases.

In 1965, Austin Bradford Hill published the article “The Environment and Disease: Association or Causation?” in the Proceedings of the Royal Society of Medicine. In the article, Hill describes nine criteria to determine if an environmental factor, especially a condition or hazard in a work environment, causes an illness. The article arose from an inaugural presidential address Hill gave at the 1965 meeting of the Section of Occupational Medicine of the Royal Society of Medicine in London, England. The criteria he established in the article became known as the Bradford Hill criteria and the medical community refers to them when determining whether an environmental condition causes an illness. The criteria outlined in “The Environment and Disease: Association or Causation?” help identify the causes of many diseases, including cancers of the reproductive system.

Exchange transfusion is the replacement of blood from newborn infants with elevated bilirubin level in their blood stream with donor blood containing normal bilirubin levels. Newborn infants that experience jaundice, the yellowing of the skin and eyes, have a buildup of bilirubin, a chemical that occurs during red blood cell breakdown, or hemolysis. Exchange transfusion is a therapy developed throughout the 1940s by Louis Diamond and a group of surgeons at the Children’s Medical Center in Boston, Massachusetts. During exchange transfusion, a physician inserts a plastic tube called a catheter through the umbilical vein of the infant to slowly remove infant blood and sequentially replace it with donor blood. Exchange transfusion was the first definitive treatment for hyperbilirubinemia in the US and it helped reduce the incidence of kernicterus, a type of brain damage caused by elevated bilirubin levels.
