Women Scientists From The United States

"entails the regulation of , cell expansion, and , and patterning of the organ as a whole. s are ideally suited to dissecting these processes. Petals are dispensable for growth and reproduction, enabling varied manipulations to be carried out with ease. In ', petals have a simple laminar structure with a small number of cell types, facilitating the analysis of organogenesis. This review summarizes recent studies that have illuminated some of the complex interplay between the s controlling petal specification, growth and differentiation in Arabidopsis. These advances, coupled with the advantages of using petals as a model , provide an excellent platform to investigate the underlying mechanisms driving plant organogenesis."

"As a graduate student, I encountered a book that still inspires me: Classic Papers in Genetics edited by . Sadly, it is now out of print, but it is a wonderful compendium of many groundbreaking papers,starting with Mendel’s ‘Experiments in Plant Hybridization’. It also includes several papers by my scientific hero, , who figured out the principle of as an undergraduate, and whose papers are a model of clarity and careful reasoning. I also really enjoy reading Peters’ prefaces to each paper, which place each work in its scientific and historical context."

"A disease of es which caused big losses to the growers occurred last June in Texas, and in August and September in Nebraska. The disease is first noticed in green full-grown tomatoes, but it is hard to detect at this stage unless close attention is given to the stems. When the fruits are green they show a little brown spot or a dark ring around and under the stem. As the fruit is shipped green, the packers may overlook this condition very easily. When the tomatoes reach their destination they have become a pink color, the disease has advanced and shows more plainly, for the stem end has then become a dark brown. The inspector notices this and, although there is not much external evidence of disease, he breaks the fruit open and finds a hard brown center. The rot is usually down the center and may extend from stem end to blossom end but sometimes it takes an oblique course and includes a portion of the seeds, darkening them also. There is no slime or ooze. Bacteria occur in great numbers in the tissues. The same organism was isolated from both the Texas and Nebraska material and the disease was reproduced in green and ripening fruits in the greenhouse, using pure cultures."

"Flowers are organized into concentric s of s, s, s and s, with each of these floral organ types having a unique role in ... Sepals enclose and protect the flower bud, while petals can be large and showy so as to attract s (or people!). Stamens produce pollen grains that contain male gametes, while the carpels contain the ovules that when fertilized will produce the seeds. While the size, shape, number and elaboration of each of these organ types can be quite different, the same general organization of four floral organ types arranged in concentric whorls exists across all species. As I shall explain in this Primer, the ‘ABC model’ is a simple and satisfying explanation for how this conserved floral architecture is genetically specified. What is the ABC model? The ABC model was first explicitly articulated in 1991, in a seminal paper by and . Although s affecting floral organ identity had been known for centuries, it was the systematic analyses of these mutations, and of the phenotypes produced by double and triple mutants, that proved to be critical in developing the ABC model."

"A bacterial leafspot disease of the occurs widespread in the Eastern States. It is mostly a disease but occurs occasionally on plants grown out of doors. The organism was isolated from diseased plants received from different sources and the disease reproduced on the leaves of healthy plants. Warm, moist conditions with poor ventilation are necessary for the organism to infect the leaves extensively. Care in regulating the temperature, air, and moisture conditions of the greenhouse and in giving plenty of space to plants grown out of doors will go far toward preventing the appearance of the disease and toward curing it when it is present. All spotted leaves should be removed and destroyed. Very sensitive varieties should be discarded. The name Bacterium pelargoni is suggested for the organism causing the disease."

"The South Carolina outbreak of lettuce-rot occurred in , the second largest lettuce-growing district on the eastern coast of the United States, with a reputation of growing the finest quality of on the entire eastern coast. The South Carolina disease may be either a stem or a leaf infection ... In an early stage the plants are a lighter green color than the healthy ones; later the head may show rot through the center or only on the top. A general wilting of the head may occur with or without visible spots or rot. In some cases rotting is rapid; in others the heart remains sound, while the outer encircling leaves are in a bad state of decay. The diseased plants are not firm in the soil, the stem is brittle, and can be easily broken off at the surface or a little below the surface of the soil. In an early stage of disease the stem when cut across shows a blue-green color; in a later stage it is brown."

"It's not easy being a pioneer. It's not easy having to prove every day that you belong. It's not easy being invisible or having your ideas credited to someone else."

"Aircraft trailing vortices have little waves that are generated and then break up....If another aircraft intercepts that trailing vortex, someone can be killed, because it’s a swirling flow....People now know that if you land airplanes three minutes apart, that’s going to be safer."

"If women don't belong in engineering, then engineering, as a profession, is irrelevant to the needs of our society. If engineering doesn't make welcome space for them, then engineering will become marginalized as other fields expand their turf to seek out and make a place for women."

"Integrity is essential. It's the inner voice, the source of self-control, the basis for the trust that is imperative in today's military. It's doing the right thing when nobody's looking."

"Interviewing individual group members separately affords privacy and encourages all members to answer. Respondents may be more frank if that others in the group will not hear what they say (thereby removing the possibility of group sanctions). This may be the best way of obtaining responses from individuals with lower positions (younger, lower , e.g.) in the group, who might be intimidated by a group interview situation."

"... one seems forced to conclude that a disproportionally large number of the nation's "pockets of poverty" are found in rural-farm areas."

"Remember that, as a sociologist, your focus is on social interaction—i.e., not on the biological or psychological processes of the actors, but on their and expression to each other of their underlying orientation, feelings, and attitudes."

"Possibly overshadowed by Matilda’s many public accomplishments is her service as a teacher and mentor at and , and the dedication and accomplishments of some of her students and menses to the study of aging and the life course, especially Anne Foner, Marilyn Johnson, and Kathleen Bond. She built a modern sociology-anthropology department at and was named the Daniel B. Fayerweather Professor of Political Economy and Sociology in 1975; in 1996 the building housing the department was named in her honor, and she received honorary doctoral degrees from (1972), Rutgers (1983), (1994), and the (1997)."

"Because of unprecedented increases in , the structure has been transformed. Linkages among family members have been prolonged, and the surviving generations in a family have increased in number and complexity. Today's kinship structure (which has no parallel in history) can be viewed in a new way: as a latent web of continually shifting linkages that provide the potential for activating and intensifying close family relationships. These relationships are no longer prescribed as strict obligations, but must be earned—created and recreated by family members over their lives. Such changes in the structure and dynamics of family relationships raise many questions and issues for students of the family including the development of special research approaches needed to understand the complexity of these relationships and the nature of older people's family relationships in the future."

"Parents who believed in the value of "getting ahead" started to apply pressure from the beginning of the school career."

"In 1979 at the age of 68, Matilda embarked on a 20-year career at the (NIA) of the (NIH). The NIA’s founding director, , and the NIH Director, , invited Matilda to establish the NIA’s granting program on Social and Behavioral Research (SBR) as well as to guide the expansion and integration of these disciplines throughout the NIH. During her first year at the NIA, she and Kathleen Bond (one of her former graduate students) developed and implemented a multidisciplinary vision for research on aging that integrated the aging of individuals into societal structures. This program emphasized the influence of social structures on the lives of individuals (Matilda exclaimed often, “People don’t grow up and grow old in laboratories—they grow up and grow old in changing societies.”) and the lives of individuals on social structures. This vision extended to the biological sciences, for Matilda recognized the need for a biopsychosocial understanding. The publication of this blueprint as a NIH program announcement set the course of NIA’s program and influences its direction even to this day."

"Today's social structures and norms are the vestigial remains of the nineteenth-century, when most people died before their work was finished or their last child had left home. Age 65 was established as the criterion for —yet age 65 is still used in many countries under today's utterly changed conditions of longevity."

"Her kindred have a prior right and can use that right to separate her from him or protect her from him, should he mistreat her….not only does the woman (under our white nation) lose her independent hold on her property and herself, but there are offenses and injuries which…would be avenged and punished by her relatives under tribal law, but which have no penalty or recognition under our lawas… At the present time, all property is personal…a wife is as independent in the uses of her possessions as is the most independent man in our midst….While I was living with the Indians, my hostess one day gave away a very fine horse….I asked, ,will your husband like to have you give the horse away?….I tried to explain how a white woman would act, but laughter and contempt met my explanation of the white man's hold upon his wife's property….As I have tried to explain our statutes to Indian women, I have met with one response. They have said, "As an Indian woman, I was free, I owned my home, my person, the work of my hands, and my children could never forget me.I was better as an Indian woman than under white law."

"Man is a product of the earth’s surface. This means not merely that he is a child of the earth, dust of her dust; but that the earth has mothered him, fed him, set him tasks, directed his thoughts, confronted him with difficulties that have strengthened his body and sharpened his wits, given him his problems of navigation or irrigation, and at the same time whispered hints for their solution"

"At the present time all property is personal; the man owns his own ponies and other belongings he has personally acquired; the woman owns her horses, dogs, and all the lodge equipments; children own their own articles; and parents do not control the possessions of their children. There is no family property as we use the term. A wife is as independent as the most independent man in our midst. If she chooses to give away or sell all of her property, there is no one to gainsay her."

"When I was living with the Indians, my hostess, a fine looking woman, who wore numberless bracelets, and rings in her ears and on her fingers, and painted her face like a brilliant sunset, one day gave away a very fine horse. I was surprised, for I knew there had been no family talk on the subject, so I asked: “Will your husband like to have you give the horse away?” Her eyes danced, and, breaking into a peal of laughter, she hastened to tell the story to the other women gathered in the tent, and I became the target of many merry eyes. I tried to explain how a white woman would act, but laughter and contempt met my explanation of the white man’s hold upon his wife’s property."

"An important characteristic of plains is their power to facilitate every phase of historical movement; that of mountains is their power to retard, arrest, or deflect it. Man, as part of the mobile envelope of the earth, like air and water feels always the pull of gravity."

"...the woman owns her horses, dogs, and all the lodge equipments; children own their own articles; and parents do not control the possessions of their children … A wife is as independent as the most independent man in our midst.” Combined with the fact that among many tribes, female elders chose, advised, and could depose the male chief and signed treaties with the U.S. government along with male leaders-and that women could divorce and controlled their own fertility though a knowledge of herbs and timing-this caused indigenous women to be seen as immoral and tribal systems to be ridiculed as “petticoat government."

"Imperceptibly a change had been wrought in me until I no longer felt alone in a strange, silent country. I had learned to hear the echoes of a time when every living thing upon this land and even the varied overshadowing skies had its voice, a voice that was attentively heard and devoutly heeded by the ancient people of America. Henceforth, to me the plants, the trees, the clouds and all things had become vocal with human hopes, fears and supplications."

"The Indian may now become a free man; free from the thralldom of the tribe; free from the domination of the reservation system; free to enter into the body of our citizens. This bill may therefore be considered as the Magna Carta of the Indians of our country."

"... I started to contact other grape geneticists in labs all over the world—initially 10 or 15 different research groups in France, Italy, Germany, Spain, Australia, New Zealand, Chile, South Africa—and proposed that we form a consortium to develop these s. Each lab would try to develop a few markers and then contribute those markers to the general pool that we would share. We formed the . After a couple of years we had developed several hundred markers. We were able to make some interesting discoveries by just using a couple of dozen markers, because that is enough to prove statistically whether one variety is related to another variety. But once several hundred markers existed it was then possible to develop a of grape, a project that was really just starting around the time that I retired from . The highlight of my career was using these s to reveal genetic relationships among classic s and to then elucidate from that something about the ."

"Methods to introduce s, either from or other organisms, into existing are now well-established and permit the targeted modification of existing grape cultivars. This may provide a means to reduce disease losses and usage in classic cultivars without otherwise changing their wine attributes."

"With potent new analysis tools, researchers could capture a species’ unique genetic fingerprint to trace its origins and evolutionary history. Once s for grapes became available, Meredith and her team at quickly harnessed the power of DNA fingerprinting to identify classic vinifera varieties and resolve longstanding questions about their murky history. Meredith and grad student John Bowers even surprised themselves in 1996 by revealing a mixed heritage of white () and red () grapes for . And in what many call her crowning achievement, Meredith—whose place in the wine pantheon was secured by a 2009 induction into the Vintners Hall of Fame—confirmed that , long claimed California’s “historic” native, is the genetic twin of the nearly extinct Crljenak Kastelanski grape variety, once grown along ’s n Coast."

"is the study of . The primary foci of demography are rates and levels of , , and and how these all interact to produce population growth (or decline), density, and age- and sex-structures; how these rates or levels vary across time and space and what produces such variation; and what consequences these have on other aspects of human (or nonhuman) existence. These demographic phenomena lie at the very heart of . occurs as a result of differential fertility and mortality within a population; gene flow occurs because of migration between populations; and the effects of genetic drift are dependent upon population size, which is an outcome of the interactions among mortality, fertility, and migration (Gage, DeWitte, & Wood, 2012). These demographic forces also affect, are affected by, and reflect many of the things that anthropologists find most interesting. For example, the age–sex structure of a population influences the population’s ratio of consumers to producers and numbers of potential marriage partners, and thus places limits on such things as subsistence strategies and household structure."

"The medieval (c. 1347-1351) was one of the most devastating s in human history. It killed tens of millions of Europeans, and recent analyses have shown that the disease targeted elderly adults and individuals who had been previously exposed to physiological stressors. Following the epidemic, there were improvements in standards of living, particularly in dietary quality for all socioeconomic strata."

"Much of the published bioarchaeological research on the has been done using samples from the in London. The location, purpose, and dimensions of East Smithfield are recorded in historical documents. Reports of the Black Death preceded its arrival in London, and East Smithfield was established in anticipation of the high mortality that would result in the city (Grainger et al. 2008, Hawkins 1990). The Black Death arrived in 1349 and lasted in London until 1350; East Smithfield was used only during the Black Death, so most, if not all, of the people buried there were victims of the disease. East Smithfield was partially excavated in the 1980s as part of the larger Royal Mint site, and more than 600 individuals interred in single burials or mass burial trenches were excavated from the cemetery."

"It was hoped that some light might be thrown on the length of life of normal blood corpuscles and the mechanism of their removal from the circulation by the study of the elimination of transfused blood, which it is possible to make when the transfused blood is of a group unlike that of the recipient. This study has brought to light two facts, first, that the length of time that transfused blood remains in the circulation varies greatly; and second, that the elimination is not a continuous process but takes place in more or less cyclic crises, so that the circulation seems to rest more heavily on this cyclic activity of the body than on the condition of the corpuscle."

"Evidence is presented to show that there is no toxin producing the in . Partial evidence is presented to show that the periods of active blood destruction which are seen as the exception in pernicious anemia cases during a series of transfusions are due to the activity of the blood-destroying organs of the body rather than to the intrinsic weakness of the pernicious anemia blood corpuscle. It is questionable whether blood destruction is as important a factor in producing the anemia of pernicious anemia as it is at present usually assumed to be."

"Ashby accurately measured the life span of s to be up to 110 days, contradicting the perceived convention of an erythrocytic life span of only 14-21 days. She was best known for developing the Ashby technique for determining red blood cell survival, but also contributed to the diagnosis of and studied in the brain. Ashby was also an amateur pianist and composer with numerous compositions published between 1955-1968."

"In a previous publication I showed that the transfused red blood-corpuscle does not have a transitory existence in the body, but that it remains in the blood-stream for a considerable length of time. The method used to show this is dependent on the iso-agglutinins present in blood and is based on the fact (which demonstrated with in vitro mixtures of blood corpuscles) that corpuscles belonging to two different blood groups if mixed can be separated quantitatively from one another by treating with a serum that will differentially agglutinate the corpuscles of one kind, leaving the others free. This method applies equally well to in vivo mixtures; the transfused blood-corpuscles in a patient can be separated from. the recipient’s native corpuscles by differentially agglutinating the recipient’s corpuscles with appropriate serum, provided the donor and recipient are in different groups. This method is only applicable, of course, to cases in which patients belonging to (’s nomenclature) are transfused with Group IV blood, or in which patients belonging to Group I are transfused with Group II or Group III blood, but in these cases the history of the transfused blood can be followed readily."

"1. It is possible in mixtures of corpuscles of different groups to separate the corpuscles practically quantitatively by treating with a serum that agglutinates the corpuscles of one kind, leaving the others unagglutinated. 2. After a recipient has been transfused with blood of a group other than his own, specimens of his blood treated with a serum that will agglutinate his own corpuscles but not the transfused corpuscles show unagglutinated corpuscles in large numbers. 3. These unagglutinated corpuscles which appear in the recipien's blood after such a transfusion are the transfused corpuscles and their count is a quantitative indicator of the amount of transfused blood still in the recipient's circulation. 4. The life of the transfused corpuscle is long; it has been found to extend for 30 days and more. The beneficial results of transfusion are without doubt not due primarily to a stimulating effect on the bone marrow, but, it is reasonable to assume, to the functioning of the transfused blood corpuscles."

"The 25 species of ' and one of ' (family ) are obligate s of 10 species of facultatively symbiotic sea anemones. Throughout the tropical Indo-West Pacific range of the relationship, a fish species inhabits only certain of the hosts potentially available to it. This specificity is due to the fishes. Five fishes occupy six sea anemone species at , , Australia. harbors P. biaculeatus, A. melanopus and A. akindynos. ... ns cleared of symbionts disappeared within 24 h, probably having been eaten by reef fishes. Entacmaea, the most abundant and widespread host actinian at Lizard Island and throughout the range of the association, is also arguably the most attractive to es. I believe its vulnerability to predation was a factor in its evolving whatever makes it desirable to fishes. Experimental transfers pitted fish of one species against those of another, controlling for ecophenotype of host, and sex, size and number of fish. Competitive superiority was in the same order as abundance and over-all host specificity: P. biaculeatus, A. melanopus, A. akindynos. At least three factors are necessary to explain patterns of species specificity — innate or learned host preference, competition, and es."

"Have no fear of perfection; you'll never reach it."

"are secreted by the of all ns and only cnidarians. Of the three categories of cnidae (also called cnidocysts), s occur in all cnidarians, and are the means by which cnidarians defend themselves and obtain prey; s and s are restricted to a minority of major . A cnida discharges by eversion of its tubule; venom may be associated with the tubule of a nematocyst. About 30 major morphological types of nematocysts are recognized, but no single nomenclature for them is accepted."

"Well I thought about my formula. Hard work, a little bit of luck, a little bit of talent and a lot of help from my friends, students and professors."

"For me, it was all right. There were very few bumps along the way. I think it helps that you work very hard and you enjoy it. Yeah. That is my advice to young people. First of all, you need to find something that really you love and then do everything you can to preserve that. There’s no easy road to be creative, I think."

"A really strong woman accepts the war she went through and is ennobles by her scars."

"Talbot worked on the paleontology of both vertebrates and . Her contributions to invertebrate paleontology included a revision of the s of New York State and the investigation of Stafford limestone, also in New York State. Her discovery of the approximately eighteen-centimeter dinosaur , in the Triassic sandstone near , established her reputation in vertebrate paleontology. She postulated that this small dinosaur was a bipedal carnivore."

"In a bowlder of which the glacier carried two or three miles, possibly, and deposited not far from the site of , the writer recently found an excellently preserved skeleton of a small dinosaur the length of whose body is about 18. The bowlder was split along the plane in which the fossil lies and part of the bones are in one half and part in the other. These bones are hollow and the whole framework is very light and delicate."

"Women are in many respects superior to men, since generally speaking, they have more patience and often more taste and discrimination in arranging collections and more deftness in manipulating materials. How true this is!"

"The ultimate goal of my research is to improve our knowledge of how changes in climate and land-use will affect forest ecosystems and water resources."

"I investigate how forest processes affect water flow dynamics and pathways in soil and streams, and conversely, how water flow paths affect ecological function in mountainous areas. This bridging of hydrology and ecosystem science is key to developing sustainable management of water resources."

"All of my research involves a combination of field experimentation, field observations and laboratory analysis, and is fundamentally interdisciplinary and collaborative."

"Over my career, I have collaborated with dozens of excellent scientists from a variety of disciplines to conduct research projects that have achieved far more than any of us could have on our own."
