"How do Embryos Assess Risk? Vibrational Cues in Predator-Induced Hatching of Red-Eyed Treefrogs" (2005), by Karen Warkentin Karla T. Moeller In 'How do Embryos Assess Risk? Vibrational Cues in Predator-Induced Hatching of Red-Eyed Treefrogs' (2005), Karen Warkentin reported on experiments she conducted to see how red-eyed treefrog embryos, Agalychnis callidryas, can distinguish between vibrations due to predator attacks and other environmental occurrences, such as storms. Though the ability of red-eyed treefrogs to alter their hatch timing had been documented, the specific cues that induce early hatching were not well understood. 2012-04-07 4 Jul 2018 - 4:40:59am
Lynn Petra Alexander Sagan Margulis (1938-2011) Dorothy Regan Haskett Lynn Petra Alexander Sagan Margulis was an American biologist, whose work in the mid-twentieth century focused on cells living together in a mutually advantageous relationship, studied cells and mitochondria in the US during the second half of the twentieth century. She developed a theory for the origin of eukaryotic cells, that proposed two kinds of structures found in eukaryotic cells mitochondria in animals, and plastids in plantsÑwere once free-living bacteria that lived harmoniously and in close proximity to larger cells, a scenario called symbiosis. 2014-03-23 4 Jul 2018 - 4:40:59am
Arthur Earl Walker (1907-1995) Alexandra Bohnenberger Arthur Earl Walker was a medical researcher and physician who studied the brain and neurosurgery in the United States during the twentieth century. Walker examined the connections of the thalamus to the rest of the brain and how the thalamus coordinates sensory signals. The thalamus is a cluster of nerve cells located between the two hemispheres of the brain and it is responsible for consciousness and sensory interpretation. 2017-03-07 4 Jul 2018 - 4:40:59am
Sir Graham Collingwood Liggins (1926-2010) Kathleen O'Connor Sir Graham Collingwood Liggins devoted much of his professional life to obstetric research. Liggins demonstrated that hormones created by the fetus helped initiate labor, rather than hormones originating solely from the mother. Liggins also discovered that cortisol given to pregnant mothers helped delay premature labor, and that it increased the likelihood that premature infants would breathe normally after birth. Prior to cortisol treatment, premature infants often died of respiratory distress syndrome characterized by the inability to inflate immature lungs. 2012-02-16 4 Jul 2018 - 4:40:59am
Biological Lectures Delivered at the Marine Biological Laboratory in Woods Hole EP Editorial Team The Marine Biological Laboratory in Woods Hole, Massachusetts, began in 1888 with one building housing researchers upstairs and students in a shared lab and lecture space downstairs. For the first two years, instruction took the form of general lectures covering a range of topics in zoology. In addition, the trustees offered some public lectures in Boston to raise funds for the lab. 2008-10-24 4 Jul 2018 - 4:40:59am
Clomiphene Citrate Tian Zhu Clomiphene citrate, more commonly known by its brand names Clomid and Serophene, is a medication prescribed to women to stimulate ovulation in order to treat infertility. It stimulates ovulation in women who do not ovulate or ovulate irregularly. This drug was created by Dr. Frank Palopoli in 1956 while he worked for Merrell Company. It first successfully induced ovulation in women in 1961 and was approved by the Federal and Drug Administration (FDA) in 1967. 2009-07-25 4 Jul 2018 - 4:40:59am
Franz Julius Keibel (1861-1929) M. Elizabeth Barnes Franz Keibel studied the embryos of humans and other animals in Europe at the turn of the twentieth century. He lived and worked in several different parts of Germany and France. Keibel drew illustrations of embryos in many stages of development. Keibel used these illustrations, which he and others in the scientific community called normal plates, to describe the development of organisms in several species of vertebrates. 2014-06-21 4 Jul 2018 - 4:40:59am
"CRISPR /Cas9-mediated Gene Editing in Human Tripronuclear Zygotes" (2015), by Junjiu Huang et al. Meilin Zhu In 2015, Junjiu Huang and his colleagues reported their attempt to enable CRISPR/cas 9-mediated gene editing in nonviable human zygotes for the first time at Sun Yat-Sen University in Guangzhou, China. Their article, CRISPR /Cas9-mediated Gene Editing in Human Tripronuclear Zygotes, was published in Protein and Cell. Nonviable zygotes are sperm-fertilized eggs that cannot develop into a fetus. Researchers previously developed the CRISPR/cas 9 gene editing tool, which is a system that originated from bacteria as a defense mechanism against viruses. 2017-11-08 4 Jul 2018 - 4:40:59am
Ziegler Wax Embryo Models Karen Wellner Three-dimensional anatomical models have long been essential to the learning of science and lend a sense of "control" to those practicing in the field. As the development of embryology grew in importance during the late 1800s, so did the need for models to show intricate details of embryos. 2010-06-15 4 Jul 2018 - 4:40:59am
Michael D. West (1953- ) Lijing Jiang Michael D. West is a biomedical entrepreneur and investigator whose aim has been to extend human longevity with biomedical interventions. His focus has ranged from the development of telomerase-based therapeutics to the application of human embryonic stem cells in regenerative medicine. Throughout his eventful career, West has pursued novel and sometimes provocative ideas in a fervent, self-publicizing manner. As of 2009, West advocated using human somatic cell nuclear transfer techniques to derive human embryonic stem cells for therapeutic practice. 2010-06-23 4 Jul 2018 - 4:40:59am
Frank Rattray Lillie (1870-1947) Karen Wellner Frank R. Lillie was born in Toronto, Canada, on 27 June 1870. His mother was Emily Ann Rattray and his father was George Waddell Little, an accountant and co-owner of a wholesale drug company. While in high school Lillie took up interests in entomology and paleontology but went to the University of Toronto with the aim of studying ministry. He slowly became disillusioned with this career choice and decided to major in the natural sciences. It was during his senior year that he developed his lifelong interest in embryology. 2009-07-22 4 Jul 2018 - 4:40:59am
The Silent Scream (1984), by Bernard Nathanson, Crusade for Life, and American Portrait Films Mark Zhang The Silent Scream is an anti-abortion film released in 1984 by American Portrait Films, then based in Brunswick, Ohio. The film was created and narrated by Bernard Nathanson, an obstetrician and gynecologist from New York, and it was produced by Crusade for Life, an evangelical anti-abortion organization. In the video, Nathanson narrates ultrasound footage of an abortion of a twelve-week-old fetus, claiming that the fetus opened its mouth in what Nathanson calls a silent scream during the procedure. 2013-05-02 4 Jul 2018 - 4:40:59am
Austin Bradford Hill (1897-1991) Carolina Abboud During the twentieth century, Austin Bradford Hill researched diseases and their causes in England and developed the Bradford Hill criteria, which comprise the minimal requirements that must be met for a causal relationship to be established between a factor and a disease. Hill also suggested that researchers should randomize clinical trials to evaluate the effects of a drug or treatment by monitoring large groups of people. 2017-06-15 4 Jul 2018 - 4:40:59am
Julia Clifford Lathrop (1858–1932) Katherine Madgett Julia Clifford Lathrop was an activist and social reformer in the late nineteenth to early twentieth centuries and the first chief of the United States Children’s Bureau. In that capacity, she conducted demographic studies to identify links between socioeconomic factors and infant mortality rates. Lathrop mobilized the effort to increase birth registration and designed programs and publications to promote infant and maternal health throughout the US. 2017-05-22 4 Jul 2018 - 4:40:59am
The Comstock Law (1873) Sheraden Seward The Comstock Law was a controversial law because it limited the reproductive rights of women and violated every person's right to privacy. This federal law was the beginning of a long fight over the reproductive rights of women which is still being waged. Reproductive rights are important to embryology because they lead to the discussions regarding the morality of abortion, contraceptives, and ultimately the moral status of the embryo. 2009-01-13 4 Jul 2018 - 4:40:59am
"The Adaptive Significance of Temperature-Dependent Sex Determination in a Reptile" (2008), by Daniel Warner and Richard Shine Karla Moeller In 2008 researchers Daniel Warner and Richard Shine tested the Charnov-Bull model by conducting experiments on the Jacky dragon (Amphibolurus muricatus), in Australia. Their results showed that temperature-dependent sex determination(TSD) evolved in this species as an adaptation to fluctuating environmental temperatures. The Charnov-Bull model, proposed by Eric Charnov and James Bull in 1977, described the evolution of TSD, although the model was, for many years, untested. 2013-10-07 4 Jul 2018 - 4:40:59am
Fetal Surgery Kathleen O'Connor, Erica O'Neil Fetal surgeries are a range of medical interventions performed in utero on the developing fetus of a pregnant woman to treat a number of congenital abnormalities. The first documented fetal surgical procedure occurred in 1963 in Auckland, New Zealand when A. William Liley treated fetal hemolytic anemia, or Rh disease, with a blood transfusion. 2012-11-01 4 Jul 2018 - 4:40:59am
Santiago Felipe Ramon y Cajal (1852-1934) Sarah Taddeo Santiago Felipe Ramon y Cajal investigated brains in the nineteenth and twentieth centuries in Spain. He identified and individuated many components of the brain, including the neuron and the axon. He used chick embryos instead of adult animals, then customary in brain research, to study the development and physiology of the cerebellum, spinal cord, and retina. Ramon y Cajal received the Nobel Prize in Physiology and Medicine in 1906, along with Camillo Golgi, for his work on the structure of the nervous system. 2014-06-05 4 Jul 2018 - 4:40:59am
The Debate over DNA Replication Before the Meselson-Stahl Experiment (1953–1957) Victoria Hernandez Between 1953 and 1957, before the Meselson-Stahl experiment verified semi-conservative replication of DNA, scientists debated how DNA replicated. In 1953, James Watson and Francis Crick proposed that DNA was composed of two helical strands that wound together in a coil. Their model suggested a replication mechanism, later termed semi-conservative replication, in which parental DNA strands separated and served as templates for the replication of new daughter strands. 2018-01-03 4 Jul 2018 - 4:40:59am
Planned Parenthood v. Casey (1992) Sheraden Seward Almost ten years after the landmark decision in Roe v. Wade (1973) the battle over abortion was still being waged. The reproductive rights of women in the United States were being challenged yet again by the Pennsylvania Abortion Control Act of 1982. The act was comprised of four provisions that restricted the fundamental right a woman had to obtaining an abortion, as established in Roe v. Wade. The four provisions included spousal notification, information disclosure, a twenty-four hour waiting period, and parental consent for minors. 2009-01-13 4 Jul 2018 - 4:40:59am
The Jackson Laboratory Christina Raup The Roscoe B. Jackson Laboratory, known commonly in the scientific field as the Jackson Laboratory, was founded by Clarence Cook Little in May 1929. The lab has been pivotal in research with in vitro fertilization, teratomas, gene replacement therapy for birth defects, and more because its researchers have focused from the beginning on developing the mouse as a model organism. Mice were chosen by researchers at Jackson as the best available model for genetic research, and today genetically uniform strains of mice developed at the lab are used in laboratories all over the world. 2010-07-01 4 Jul 2018 - 4:40:59am
Carnegie Stages Karen Wellner Historically the exact age of human embryo specimens has long perplexed embryologists. With the menstrual history of the mother often unknown or not exact, and the premenstrual and postmenstrual phases varying considerably among women, age sometimes came down to a best guess based on the weight and size of the embryo. Wilhelm His was one of the first to write comparative descriptions of human embryos in the late 1800s. Soon afterward, Franklin P. Mall, the first director of the Carnegie Institution of Washington's (CIW) Department of Embryology, expanded upon His' work. 2009-07-17 4 Jul 2018 - 4:40:59am
Edgar Allen (1892–1943) Brendan Van Iten Edgar Allen identified and outlined the role of female sex hormones and discovered estrogen in the early 1900s in the US. In 1923, Allen, through his research with mice, isolated the primary ovarian hormone, later renamed estrogen, from ovarian follicles and tested its effect through injections in the uterine tissues of mice. Allen’s work on estrogen, enabled researchers to further study hormones and the endocrine system. 2017-07-23 4 Jul 2018 - 4:40:59am
The Effects of Gene Regulation on Aging in Caenorhabditis elegans (2003) Dasia Garcia In 2003, molecular biology and genetics researchers Coleen T. Murphy, Steven A. McCarroll, Cornelia I. Bargmann, Andrew Fraser, Ravi S. Kamath, Julie Ahringer, Hao Li, and Cynthia Kenyon conducted an experiment that investigated the cellular aging in, Caenorhabditis elegans (C. elegans) nematodes. The researchers investigated the interactions between the transcription factor DAF-16 and the genes that regulate the production of an insulin-like growth factor 1 (IGF-1-like) protein related to the development, reproduction, and aging in C. elegans. 2017-02-16 4 Jul 2018 - 4:40:59am
Ernst Haeckel's Biogenetic Law (1866) M. Elizabeth Barnes The biogenetic law is a theory of development and evolution proposed by Ernst Haeckel in Germany in the 1860s. It is one of several recapitulation theories, which posit that the stages of development for an animal embryo are the same as other animals' adult stages or forms. Commonly stated as ontogeny recapitulates phylogeny, the biogenetic law theorizes that the stages an animal embryo undergoes during development are a chronological replay of that species' past evolutionary forms. 2014-05-03 4 Jul 2018 - 4:40:59am
Dizhou Tong (1902-1979) Yawen Zou Dizhou Tong, also called Ti Chou Tung, studied marine animals and helped introduce and organize experimental embryology in China during the twentieth century. He introduced cellular nuclear transfer technology to the Chinese biological community, developed methods to clone organisms from many marine species, and investigated the role of cytoplasm in early development. Tong's administrative and scientific leadership in the fields of marine, cellular, and developmental biology contributed to China's experimental embryology research programs. 2014-02-18 4 Jul 2018 - 4:40:59am
Walter Edward Dandy (1886-1946) Alexandra Bohnenberger Walter Edward Dandy studied abnormalities in the developing human brain in the United States in the twentieth century. He collaborated with pediatrician Kenneth Blackfan to provide the first clinical description of Dandy-Walker Syndrome, a congenital brain malformation in which the medial part of the brain, called the cerebellar vermis, is absent. Dandy also described the circulation of cerebral spinal fluid, the clear, watery fluid that surrounds and cushions the brain and spinal cord. 2017-03-02 4 Jul 2018 - 4:40:59am
Johannes Holtfreter (1901-1992) Adam R. Navis Johannes Holtfreter made important discoveries about the properties of the organizer discovered by Hans Spemann. Although he spent much time away from the lab over many years, he was a productive researcher. His colleagues noted that the time he spent away helped revitalize his ideas. He is credited with the development of a balanced salt medium to allow embryos to develop; the discovery that dead organizer tissue retains inductive abilities; and the development of specification, competence, and distribution of fate maps in the developing frog embryo. 2008-02-29 4 Jul 2018 - 4:40:59am
Congenital Vertebral Defects Corinne DeRuiter The spinal column is the central structure in the vertebrate body from which stability, movement, and posture all derive. The vertebrae of the spine are organized into four regions (listed in order from cranial to caudal): cervical, thoracic, lumbar, and pelvic. These regions are classified by their differences in curvature. The human spine usually consists of thirty-three vertebrae, seven of which are cervical (C1-C7), twelve are thoracic (T1-T12), five are lumbar (L1-L5), and nine are pelvic (five fused as the sacrum and four fused as the coccyx). 2010-09-12 4 Jul 2018 - 4:40:59am
Karl Ernst von Baer (1792-1876) Kimberly A. Buettner Best known for his contributions to the field of embryology, Karl Ernst von Baer also pursued a variety of other areas of study including medicine, botany, zoology, and anthropology. Committing his life to scientific research, von Baer's work led to the advancement of the understanding of mammalian reproduction, development, and organ functioning. His embryological discoveries ultimately led him to a view of development that supported epigenesis and refuted long-held thinking about preformation. 2007-10-31 4 Jul 2018 - 4:40:59am
"Genetic Evidence Equating SRY and the Testis-Determining Factor" (1990), by Phillippe Berta et al. Troy Cox In the late 1980s, Peter Goodfellow in London, UK led a team of researchers who showed that the SRY gene in humans codes a protein that causes testes to develop in embryos. During this time, scientists in London and Paris, including Peter Koompan and John Gubbay, proposed that SRY was the gene on the Y chromosome responsible for encoding the testis-determining factor (TDF) protein. The TDF is a protein that initiates embryo to develop male characteristics. 2014-01-10 4 Jul 2018 - 4:40:59am
Francois Jacob (1920-2013) Valerie Racine Francois Jacob studied in bacteria and bacteriophages at the Institut Pasteur in Paris, France, in the second half of the twentieth century. In 1965, Jacob won the Nobel Prize in Physiology or Medicine with Andre M. Lwoff and Jacques L. Monod for their work on the genetic control of enzyme synthesis. Jacob studied how genes control and regulate metabolic enzymes in the bacterium Escherichia coli (E. coli) and in lysogenic bacterial systems. He contributed to theories of transcriptional gene 2014-09-29 4 Jul 2018 - 4:40:59am

Narayan published the article “Child Development in the Context of Disaster, War, and Terrorism: Pathways of Risk and Resilience” in Annual Reviews in Psychology. The authors conducted their study at the Institute of Child Development at the University of Minnesota in Minneapolis, Minnesota. In the article, Masten and Narayan review a number of articles to examine and compile the research made since the twenty-first century on the psychological impact of mass trauma, such as war, terrorism, and disasters, on children. 2017-11-15 4 Jul 2018 - 4:40:59am
Ectopic Pregnancy Tian Zhu Many difficulties can arise with a pregnancy even after the sperm successfully fertilizes the oocyte. A major problem occurs if the fertilized egg tries to implant before reaching its normal implantation site, the uterus. An ectopic pregnancy occurs when a fertilized egg implants anywhere other than in the uterus, most commonly in the fallopian tubes. Ectopic pregnancies cannot continue to term, so a physician must remove the developing embryo as early as possible. 2010-05-06 4 Jul 2018 - 4:40:59am
Stem Cell Tourism Christina Raup When James Thomson of the University of Wisconsin announced in 1998 that he had derived and cultured human embryonic stem cells(hESCs), Americans widely believed-and accepted-that stem cells would one day be the basis of a multitude of regenerative medical techniques. Researchers promised that they would soon be able to cure a variety of diseases and injuries such as cancer, diabetes, Parkinson's, spinal cord injuries, severe burns, and many others. But it wasn't until January 2009 that the Food and Drug Administration approved the first human clinical trials using hESCs. 2010-06-14 4 Jul 2018 - 4:40:59am
Laparoscopy Olivia Conley Laparoscopy, a subfield of endoscopy, is a minimally invasive surgical procedure used to examine and operate on the internal organs of the abdomen through a small incision in the abdominal wall. The term "laparoscopy" is derived from two Greek words: laparo, meaning the soft space between hips and ribs, and skopie, meaning to examine. Today laparoscopy has broad clinical applications including for diagnosis, fertility procedures, visual representation, and surgery. 2010-06-19 4 Jul 2018 - 4:40:59am
Andrew Francis Dixon (1868-1936) S. Alexandra Aston Andrew Francis Dixon studied human anatomy and egg cells at the turn of the twentieth century in Ireland and Great Britain. Dixon studied the sensory and motor nervous system of the face, the cancellous bone tissue of the femur, supernumerary kidneys, and the urogenital system. In 1927 Dixon described a mature human ovarian follicle. This follicle, Dixon noted, contained an immature human egg cell (oocyte) with a visible first polar body and the beginnings of the second polar body. 2014-04-01 4 Jul 2018 - 4:40:59am
Apoptosis in Embryonic Development Zane Bartlett Apoptosis, or programmed cell death, is a mechanism in embryonic development that occurs naturally in organisms. Apoptosis is a different process from cell necrosis, which is uncontrolled cell death usually after infection or specific trauma. As cells rapidly proliferate during development, some of them undergo apoptosis, which is necessary for many stages in development, including neural development, reduction in egg cells (oocytes) at birth, as well as the shaping of fingers and vestigial organs in humans and other animals. Sydney Brenner, H. Robert Horvitz, and John E. 2017-06-08 4 Jul 2018 - 4:40:59am
Martius Flap Procedure to Repair Obstetric Fistulas Patsy Ciardullo The Martius flap procedure is a surgical procedure used to treat obstetric fistulas in women. Heinrich Martius developed the procedure in twentieth century Germany to treat women with urinary incontinence caused by stress, and later doctors used it to repair obstetric fistulas. Fistulas occur in pregnant women when a hole is torn between the vagina and the urinary tract (called vesicovaginal) or the vagina and the rectum (called rectovaginal). The hole, or fistula, occurs in the tissue separating two organs and therefore obstetric fistulas result in either urinary or fecal incontinence. 2017-04-10 4 Jul 2018 - 4:40:59am
The Discovery of Fetal Alcohol Syndrome Erica O'Neil The term Fetal Alcohol Syndrome (FAS) was first published in 1973 in an article published in the British medical journal The Lancet. In that article, a group of pediatricians and psychiatrists at the University of Washington Medical School helped to define the morphological defects and developmental delays that can affect children born to alcoholic mothers. Those observations include pre- and post-natal growth deficiencies, minor facial abnormalities, and damage to the developing brain that can result in behavioral, learning, and cognitive abnormalities. 2011-05-09 4 Jul 2018 - 4:40:59am
Elizabeth Maplesden Ramsey (1906-1993) Kaitlin Smith Physician and pathologist Elizabeth Maplesden Ramsey was a member of the Carnegie Institution of Washington (CIW) for thirty-nine years. The affiliation began in 1934, when Ramsey discovered what was assumed to be the youngest-known embryo at the time, and donated it to CIW's massive embryo collection. After studying embryos, Ramsey focused her research on placental circulation in primates. 2010-07-01 4 Jul 2018 - 4:40:59am
Marcello Malpighi (1646-1694) Cera R. Lawrence Marcello Malpighi studied chick embryos with microscopes in Italy during the seventeenth century. Trained as a medical doctor, he was among the first scientists to use the microscope to examine embryos at very early stages. Malpighi described early structures in chick embryos, and later scientists used his descriptions to help develop the theory of preformationism. 2008-09-12 4 Jul 2018 - 4:40:59am
Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior (1964), by Bernard Rimland Sean Cohmer Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior (hereafter Infantile Autism) is a book written by Bernard Rimland, published in 1964. The book proposed a theory to explain the causes of autism. The book also synthesized research into autism and used Rimland's neural theory, described in the book, as a theory to explain some aspects of behavior, intelligence, and abnormality. 2014-05-23 4 Jul 2018 - 4:40:59am
Priscilla White (1900–1989) Blaise Castagnetti Priscilla White studied the treatment of diabetes in mothers, pregnant women, and children during the twentieth century in the US. White began working with children with Type 1 diabetes in 1924 at Elliott Proctor Joslin’s practice in Boston, Massachusetts. Type 1 diabetes is an incurable disease where the pancreas produces little to no insulin. Insulin is a hormone that allows the body to use sugar from food for energy and store sugars for future use. Joslin and White co-authored many publications on children 2018-02-26 4 Jul 2018 - 4:40:59am
Summerfield v. Superior Court [Brief] (1985) Brock Heathcotte Arizona joined the majority of states that recognized wrongful death claims on behalf of a viable fetus, regardless of whether the child was born alive or died in the womb by expanding the definition of "person" to include a viable fetus. 2008-05-09 4 Jul 2018 - 4:40:59am
Gustav Jacob Born (1851-1900) Karen Wellner Gustav Jacob Born was an experimental embryologist whose original work with amphibians served as the platform for his wax-plate method of embryo modeling, heteroblastic (different tissues) and xenoplastic (similar species) transplantation methods, environmental influences on sex ratio studies, and proposed function of the corpus luteum. He was born 22 April 1851 in Kempen, Prussia, but his family moved to the larger city of Görlitz within a year after Born's birth. His father was Marcus Born, a physician and public health officer who practiced in the town of Görlitz. 2009-07-22 4 Jul 2018 - 4:40:59am
Karl Wilhelm Theodor Richard von Hertwig (1850-1937) Katherine Brind'Amour, Benjamin Garcia Karl Wilhelm Theodor Richard von Hertwig is an important figure in the history of embryology for his contributions of artificial hybridization of sea urchin eggs and the formulation of his coelom theory. He was born 23 September 1850 in Friedelberg, Germany, to Elise Trapp and Carl Hertwig. Richard and his older brother Oscar began their studies at Jena under the direction of Ernst Haeckel from 1868 to 1871. In 1872 Hertwig became a lecturer in zoology at Jena while Oscar lectured in anatomy and embryology. 2007-11-01 4 Jul 2018 - 4:40:59am
The Genetic Control and Cytoplasmic Expression of 'Inducibility' in the synthesis of B-galactosidase" (1959), by Arthur B. Pardee, Francois Jacob, and Jacques Monod Abhinav Mishra Between 1957 and 1959, Arthur Pardee, Francois Jacob, and Jacques Monod conducted a set of experiments at the Pasteur Institute in Paris, France, that was later called the PaJaMa Experiments, a moniker derived from the researchers' last names. In these experiments, they described how genes of a species of single-celled bacteria, called Escherichia coli (E. coli), controlled the processes by which enzymes were produced in those bacteria. 2015-05-28 4 Jul 2018 - 4:40:59am
Alfred Henry Sturtevant (1891–1970) Kevin Gleason Alfred Henry Sturtevant studied heredity in fruit flies in the US throughout the twentieth century. From 1910 to 1928, Sturtevant worked in Thomas Hunt Morgan’s research lab in New York City, New York. Sturtevant, Morgan, and other researchers established that chromosomes play a role in the inheritance of traits. In 1913, as an undergraduate, Sturtevant created one of the earliest genetic maps of a fruit fly chromosome, which showed the relative positions of genes along the chromosome. 2017-05-20 4 Jul 2018 - 4:40:59am
J.B. v. M.B. [Brief] (2001) Brock Heathcotte In a dispute over frozen embryos during a divorce case, the court decided the wife's fundamental right to not procreate mandated destruction of the pre-embryos in light of the husband's continuing ability to procreate with a different partner. The court also said embryo disposition agreements used by in vitro fertilization clinics were generally enforceable subject to either spouse's right to change his or her mind prior to use of the pre-embryos. 2008-05-09 4 Jul 2018 - 4:40:59am
