"The house and its surroundings are intimately connected with the home, each modifies the other. Hawthorne's , Poe's , there reports of investigations of housing committees, , all tell us the same story. The dwellers in a house put their stamp upon it, even when they have left it empty it reflects something of their characters and habits from its walls and floors, from the very air which has surrounded them. Still more the house modifies the home and the people who dwell in it. Disease and death come more frequently to the damp, unventilated house than to the sunlit one. The inconvenient house, making irksome the necessary work, influences the dispositions of all under its roof. The quiet dignified house with a beautiful outlook brings soothing and inspiration."

"A convenient kitchen is one in which the necessary work can be done with the least possible effort. To plan such a kitchen requires at least two things. First, there must be a clear idea of all the routine jobs to be done in the kitchen in the order that they are most likely to come. , cooking, serving, clearing away and are the jobs that follow each other most often in the majority of kitchens. Second, after the plan of work is clearly in mind, comes the choosing and placing of the needed equipment. The relation of the kitchen to the rest of the house, especially the dining portion, also plays an important part in convenience."

"Friends may come and go, but enemies accumulate."

"and their were discovered in 1977. While the hot-water springs were predicted to occur at s, no one expected to find them colonized by exotic invertebrate faunas. Accustomed to a view of the deep sea as a food-limited environment, the puzzle of how lush communities could be maintained provoked biologists into a flurry of research activity. ... As field programs multiplied and more vent communities were discovered, biogeographic patterns in the distribution of faunas became apparent and ecological issues of requirements, , and began to be addressed. associated with diverse settings, from and s to . Massive bacterial blooms triggered by the release of nutrients during a volcanic eruption, rapid colonization of new vents by invertebrates, and burial of extant vent communities by lava flows demonstrate the dynamic nature of hydrothermal systems. Perhaps the most provocative consequence of the discovery of seafloor hydrothermal vents is the ."

"in the late 1970s led to the discovery of at s. More recently, sulphide deposits containing . In addition to metal-rich ores, hydrothermal vents host ecosystems based on . Although there has been considerable effort to study the biology and ecology of vent systems in the decades since these systems were first discovered, there has been limited attention paid to conservation issues. Three priority recommendations for conservation science at hydrothermal vent settings are identified here: (i) determine the natural conservation units for key species with differing life histories; (ii) identify a set of first principles for the design of preservation reference areas and conservation areas; (iii) develop and test methods for effective mitigation and restoration to enhance the recovery of biodiversity in sulphide systems that may be subject to open-cut mining."

"ecosystems have stimulated decades of and hold promise of mineral and genetic resources that also serve societal needs. Some endemic taxa thrive only in vent environments, and vent-associated organisms are adapted to a variety of natural disturbances, from tidal variations to earthquakes and volcanic eruptions. In this paper, physicochemical and biological impacts of a range of human activities at vents are considered. , albeit at a local scale, based on our current understanding of ecological responses to disturbance. Natural recovery from a single mining event depends on immigration and larval recruitment and colonization; understanding processes and dynamics influencing life-history stages may be a key to effective minimization and mitigation of mining impacts. Cumulative impacts on of several mining projects in a single region, without proper management, include possible species extinctions and shifts in community structure and function."

"You can go for hundreds of meters along the and see nothing. But then you’ll get to a and it will be a garden of exotic creatures. The vents are like the . The seawater percolates down through cracks caused by earthquakes, and then it comes up through these underwater chimneys. There are lots of ores there like copper, gold, silver, and s. There’s so much life there, and it’s very different from what we’re used to seeing. Whenever scientists go down, we almost always find new creatures."

"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."

"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."

"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."

"The 1940s and 1950s were marked by intense debates over the origin of drug resistance in microbes. ... Antibiotic resistance became a key issue among those disputing physiological (usually termed ‘’) vs. genetic ( and ) explanations of variation in . Postwar developments connected with the gave this debate a new political valence. Proponents of the weighed in with support for the genetic theory. However, certain features of drug resistance seemed inexplicable by mutation and selection, particularly the phenomenon of ‘multiple resistance’—the emergence of resistance in a single strain against several unrelated antibiotics. In the late 1950s, and his collaborators solved this puzzle by determining that resistance could be conferred by rather than . These could carry resistance to many antibiotics and seemed able to promote their own dissemination in bacterial populations. In the end, the vindication of the genetic view of drug resistance was accompanied by a recasting of the ‘gene’ to include extrachromosomal hereditary units carried on viruses and s."

"Laboratory instructions and recipes are sometimes edited into books with a wide circulation. Even in the late twentieth century, publications of this nature remained influential. For example, s from a 1980 summer course on at provided the basis for a bestselling laboratory manual by , and . Not only did the Molecular Cloning: A Laboratory Manual become a standard reference for s (commonly called the ‘bible’), but also its recipes and clear instructions made gene cloning and technologies accessible to non-specialists. Consequently, this laboratory manual contributed to the rapid spread of genetic-engineering techniques throughout the , as well as in industry. As is often the case with how-to books, however, finding a way to update methods in this rapidly changing field posed a challenge, and various molecular-biology reference books had different ways of dealing with knowledge obsolescence. This paper explores the origins of this manual, its publication history, its reception and its rivals – as well as the more recent migration of such laboratory manuals to the Internet."

"put to work in , having induced in an inbred mouse strain (Strong A) that was particularly susceptible to the implantation of tumors ... He and K. G. Scott found that these leukemic mice concentrated more radiophosphorus in their s and s than did healthy mice after both groups received tracer doses. ... This finding stoked hopes that radioisotopes would be selectively absorbed and localized in cancer patients, where they could serve to irradiate tumors."

"There are many reasons to revisit the history of research on (TMV), beginning with the fact that it was the first virus to be identified and so marks the start of the field of . However, not every original example of a new biological category becomes a well-studied object in its own right ... As virology took off in the early twentieth century, TMV did become one of the best-studied viruses and remained at the forefront of the field. It was used to elucidate basic knowledge about the nature of viruses and served as a in as well as agriculture, where it had emerged. The fact that the first recognized virus came from plants—although es were rapidly identified—meant that virology was, from the outset, highly comparative ... Literature on the origins of often privileges and the contributions of the ... Yet early work with TMV inspired Max Delbrück and other early molecular biologists to take up the study of bacteriophages. Moreover, TMV itself became a prominent model system for understanding the molecular nature of heredity and the relationship between proteins and nucleic acids ... Notably, some of the main scientists involved in elucidating the double-helical structure of DNA were also studying TMV, which became a tool for cracking the ."

"By 1950 the nature of the virus was no longer a mystery. Viruses were known to be s, genetic units, parasites that depend on their hosts for and . But a funny thing happened on the road to this knowledge. The viruses that most shaped this emerging portrait were not the most dangerous s, but those examples, however innocuous to humans, that made good laboratory subjects. Researchers constructed general knowledge about viruses based on a few that, by reason of historical precedence or biological robustness, were intensively studied as representatives of the rest."

"s used s to reveal the sequence of chemical reactions in . s followed the assimilation and turnover of key s and tagged molecules such as to track the movement and activity of s. s labeled s with radioisotopes to follow the replication and expression of s. Physicians utilized radioisotopes such as and to diagnose and detect s. Ecologists profited as well, using to trace through the living and nonliving parts of aquatic and terrestrial landscapes, giving concrete meaning to the notion of an ecosystem."

"Like ’’’’, is part of the biologist's . The best-known model systems—standardized organisms such as the and the —are investigated by an entire community of biologists. Model systems become prototypes within which key biological questions are defined and resolved, useful precisely because they have already been so well studied. was a model system in these respects, studied and discussed by a large contingent of s, s, and other agricultural and medical researchers ..."

"... one of the virtues of Creager's admirable book is that the attentive, even if scientifically uninformed, reader will learn a great deal, not only about these subjects but more generally about the character of during the last two-thirds of the twentieth-century. By tracking the history of from the applied realm of through its acceptance as —a widely and conventionally accepted laboratory tool—Creager traces more general trends in the development of , genetics, and . ... The power of Creager's method lies in how it underlines the dynamic set of relationships between ideas and experimental practice, between the laboratory and its sources of support."

"In Life Atomic, Angela Creager weaves an engaging tale of the history of s. Much of her material came from government documents from the Manhattan Project that were declassified during the . ... Creager introduces the concepts and vocabulary of radioisotopes at a level that any reader can appreciate."

"Scientists are very curious ... We might be curious about something that looks completely irrelevant, and it turns out to be a really amazing thing. Or it could be irrelevant. We don't know. If we knew, we wouldn't be looking at it."

"I was really interested in the basic workings of nature: Why ? What is the unified theory of everything? But I realized how many easier questions we have in astrophysics: that you could actually take a lifetime and go answer them. Graduate school at MIT showed me the way to astrophysics — how it can be an amazing route to many questions, including how the universe looks, how it functions, and even particle physics questions. I didn’t plan to study s; but every step it was, “OK, it looks promising.”"

"Being a woman is hard ... The expectations are that we’ll be gorgeous, completely organized, great mothers, great wives, and great professionals ... The pressures are huge. I was always expected to bring the cookies to meetings because I’m a woman. Like, men can’t find cookies? That’s why I say: Let’s be nicer to ourselves. Diversity is very important ... When you bring in new folks who ask new questions, you change the field and the basic sciences. Women want to do great research. But we’re asking, ‘Why do we have this rule? That artificial hierarchy?’ We can be more collaborative. And I’ll tell you this ... When men suggest we speak with deeper voices if we want to get our message across, here is what I say: Gravity does not care how deep your voice is."

"is that is assumed to be absolutely stable. A seed of strange matter in a will convert the star into a . The speed at which this conversion occurs is calculated. The calculation takes into account the rate at which the and s equilibrate via s and the diffusion of strange quarks towards the conversion front. The speed is found as a function of the temperature of the star and the minimum strangeness necessary for strange matter stability. The conversion can be detected as an energy release of ∼58 MeV with different luminosities for different stages of a neutron star's evolution and as a “super-glitch” on s' frequencies."

"The Of Extreme Multi-Messenger Astrophysics (POEMMA) was designed as a Astrophysics probe-class mission to identify the sources of ) and observe s from extremely energetic transient sources. POEMMA consists of two identical spacecraft flying in a loose formation at 525 km altitude oriented to view a common atmospheric volume and to provide full-sky coverage for both types of messengers. Each spacecraft hosts a wide with a hybrid focal plane optimized to observe both the UV fluorescence signal from extensive air showers (EASs) and the optical signals from EASs."

"... except in some of the s where the opportunities for research are limited and the salaries notably low, women are not considered eligible for chairs in the sciences ... Until women are more generally given an equal chance with men in academic recognition and remuneration, it is futile to attempt to determine, in terms of s or even of scientific reputation or eminence, how much "they are able to do for the advancement of science.""

"Miss Talbot divides her book into three parts. Part I describes the changes in women's activities—industrial, educational, civic, philanthropic, domestic, and social—during the last hundred years. Part II compares the educational machinery of about fifty years ago with that of today, citing as exampels the past and the present curricula of the Boston and Chicago public schools, of , and of the , in order to show how far education has adapted itself to these changes. Part III deals with the present collegiate education of women, pointing out its characteristics, limitations, and possible modifications in the light of modern social, economic, and psychological knowledge."

"The changes which have taken place during the in the activities and position of women are the object of an interest which is widespread. These changes have been so striking that the period during which they occurred is frequently called the "woman's century." Nor is the movement a completed one; there is every reason to believe that equally marked changes will take place in the . The time has passed when women were on the whole content to drift with the current of life and accept without question or demur the lot which tradition, custom, and public opinion might dictate. The little band of leaders who did pioneer work in the last century in claiming and making new opportunities for women did brave service: in no respect did they do better service than in showing the value of ideals as a positive social force. The record of their lives will always be a source of courage to increasing numbers of women who will be eager to take an active part in controlling and directing the stream of women's activities."

"the introduction of social media does alter the landscape. It enables youth to create a cool space without physically transporting themselves anywhere. And because of a variety of social and cultural factors, social media has become an important public space where teens can gather and socialize broadly with peers in an informal way. Teens are looking for a place of their own to make sense of the world beyond their bedrooms"

"More often than not, what people put up online using social media is widely accessible because most systems are designed such that sharing with broader or more public audiences is the default. Many popular systems require users to take active steps to limit the visibility of any particular piece of shared content. This is quite different from physical spaces, where people must make a concerted effort to make content visible to sizable audiences.8 In networked publics, interactions are often public by default, private through effort"

"Privacy is not a static construct. It is not an inherent property of any particular information or setting. It is a process by which people seek to have control over a social situation by managing impressions, information flows, and context."

"When people become famous, they are often objectified, discussed, and ridiculed with little consideration for who they are as people. Fans and critics feel as though they have the right to comment on everything celebrities do with little regard to the costs that those in the crosshairs of attention will bear. The cost that celebrities pay for the supposed benefits of being rich and famous is ongoing scrutiny and a lack of privacy. Most people do not understand or appreciate the pressure that results from fame, even though public meltdowns—such as the night that Britney Spears shaved her head in front of numerous photographers—are highly publicized. The public’s obsession with obtaining information about the famous puts serious pressure on those people’s lives, as the paparazzi’s role in Princess Diana’s death so brutally reminds us.20 Few people have sympathy for the kinds of stress that gossip places on public figures who have high status and wealth. At a distance, famous people seem invulnerable"

"Just because teens can and do manipulate social media to attract attention and increase visibility does not mean that they are equally experienced at doing so or that they automatically have the skills to navigate what unfolds. It simply means that teens are generally more comfortable with—and tend to be less skeptical of—social media than adults. They don’t try to analyze how things are different because of technology; they simply try to relate to a public world in which technology is a given."

"In a world where information is easily available, strong personal networks and access to helpful people often matter more than access to the information itself."

"A great deal of the fear and anxiety that surrounds young people’s use of social media stems from misunderstanding or dashed hopes.14 More often than not, what emerges out of people’s confusion takes the form of utopian and dystopian rhetoric."

"When adults jump to fear and isolationism as their solution to managing risk, they often undermine their credibility and erode teens’ trust in the information that adults offer."

"The military wasn’t equipped to deal with people’s demand for information about their beloved pups."

"Where my beasts of their own wrong without my will and knowledge break into another’s close, I shall be punished, for I am the trespasser with my beasts.” —Anonymous case during the reign of Henry VII"

"The machine like the djinnee, which can learn and can make decisions on the basis of its learning, will in no way be obliged to make such decisions as we should have made, or will be acceptable to us.” —Norbert Wiener, mathematician and philosopher"

"It may seem preposterous today to hold a robot morally accountable for its actions, but there are already glimpses of this in how we talk about robot-caused harm—in ways that risk assigning them more agency than appropriate."

"I sometimes think that, in the desperate straits of humanity today, we would be grateful to have nonhuman friends, even if they are only the friends we build ourselves." —Isaac Asimov, Robot Visions"

"While there may be similarities here and there, my child doesn’t sense, act, or learn the way a machine does."

"The things that make us safest from others make us least from ourselves."

"Some We Love, Some We Hate, Some We Eat, is a powerful illumination of how we really behave toward animals."

"For the teens that I interviewed, privacy isn’t necessarily something that they have; rather it is something they are actively and continuously trying to achieve in spite of structural or social barriers that make it difficult to do so. Achieving privacy requires more than simply having the levers to control information, access, or visibility. Instead, achieving privacy requires the ability to control the social situation by navigating complex contextual cues, technical affordances, and social dynamics. Achieving privacy is an ongoing process because social situations are never static."

"It’s easy to think of privacy and publicity as opposing concepts, and a lot of technology is built on the assumption that you have to choose to be private or public. Yet in practice, both privacy and publicity are blurred. Rather than eschewing privacy when they encounter public spaces, many teens are looking for new ways to achieve privacy within networked publics. As such, when teens develop innovative strategies to achieve privacy, they often reclaim power by doing so. Privacy doesn’t just depend on agency; being able to achieve privacy is an expression of agency"

"Maybe any entity significantly smarter than a human being would be crippled by existential despair."

"A central challenge in addressing the sexual victimization of children is that the public is not comfortable facing the harrowing reality that strangers are unlikely perpetrators. Most acts of sexual violence against children occur in their own homes by people that those children trust.27"

"In 1995, psychiatrist Ivan Goldberg coined the term internet addiction disorder. He wrote a satirical essay about “people abandoning their family obligations to sit gazing into their computer monitor as they surfed the Internet.” Intending to parody society’s obsession with pathologizing everyday behaviors, he inadvertently advanced the idea. Goldberg responded critically when academics began discussing internet addiction as a legitimate disorder: “I don’t think Internet addiction disorder exists any more than tennis addictive disorder, bingo addictive disorder, and TV addictive disorder exist. People can overdo anything. To call it a disorder is an error."
