Book Description
How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.

Book Description
A comprehensive guide to small-space secrets and real-life solutions for living in 1,200 square feet or less. The Little Book of Living Small shows readers how to make the most of limited square footage—with grace and style—and serves as the cheerleader readers need to help themselves feel satisfied and proud of their choice to live with less. In addition to exploring both the motivation behind choosing to live in a small space, as well as the practical, everyday advice for managing a tight footprint, The Little Book of Living Small also includes case studies: 12 style-savvy, small-space dwellers open their doors and share their design secrets. Author Laura Fenton covers a range of homes including studio apartments, one- and two-bedroom houses, a tiny house, a co-living space, and even whole houses. Stylistically these homes range from urban, rural, minimalist, and country, with the unifying thread that they are all real homes of less than 1,200 square feet that offer clever solutions that readers can use in their own homes. Laura Fenton is the lifestyle director at Parents magazine. With more than fifteen years of experience, her work has appeared in major publications including Better Homes & Gardens, Country Living, Good Housekeeping, and on leading home websites including Remodelista.com, HGTV.com, ElleDecor.com, HouseBeautiful.com, Refinery29, and elsewhere. Through her writing she has explored the topic of living small for more than a decade. She lives small with her husband, a photographer, and their son in Jackson Heights, Queens, in New York.

Book Description
The #1 New York Times–bestselling author of All Creatures Great and Small reflects on the rewards of training the next generation of veterinarians. As an aging James Herriot begins to see more house pets than livestock, the challenge of treating animals—and reassuring their owners—provides plenty of excitement, mystery, and moments of sheer delight. After building up his own practice, the renowned country vet begins to teach a new generation about a business both old-fashioned and very modern. He watches with pride as his own children show a knack for medicine, and remarks on the talents and quirks of a string of assistants. There is no perfecting the craft, since people and their animals are all remarkably different, but Herriot proves that the best healers are also the most compassionate.

Small Animals

Small Animals PDF Author: Kim Brooks
Publisher: Flatiron Books
ISBN: 1250089565
Category : Social Science
Languages : en
Pages : 257

Book Description
"It might be the most important book about being a parent that you will ever read." —Emily Rapp Black, New York Times bestselling author of The Still Point of the Turning World "Brooks's own personal experience provides the narrative thrust for the book — she writes unflinchingly about her own experience.... Readers who want to know what happened to Brooks will keep reading to learn how the case against her proceeds, but it's Brooks's questions about why mothers are so judgmental and competitive that give the book its heft." —NPR One morning, Kim Brooks made a split-second decision to leave her four-year old son in the car while she ran into a store. What happened would consume the next several years of her life and spur her to investigate the broader role America’s culture of fear plays in parenthood. In Small Animals, Brooks asks, Of all the emotions inherent in parenting, is there any more universal or profound than fear? Why have our notions of what it means to be a good parent changed so radically? In what ways do these changes impact the lives of parents, children, and the structure of society at large? And what, in the end, does the rise of fearful parenting tell us about ourselves? Fueled by urgency and the emotional intensity of Brooks’s own story, Small Animals is a riveting examination of the ways our culture of competitive, anxious, and judgmental parenting has profoundly altered the experiences of parents and children. In her signature style—by turns funny, penetrating, and always illuminating—which has dazzled millions of fans and been called "striking" by New York Times Book Review and "beautiful" by the National Book Critics Circle, Brooks offers a provocative, compelling portrait of parenthood in America and calls us to examine what we most value in our relationships with our children and one another.

The Oldest Living Things in the World

The Oldest Living Things in the World PDF Author: Rachel Sussman
Publisher: University of Chicago Press
ISBN: 022605764X
Category : Nature
Languages : en
Pages : 305

Book Description
The Oldest Living Things in the World is an epic journey through time and space. Over the past decade, artist Rachel Sussman has researched, worked with biologists, and traveled the world to photograph continuously living organisms that are 2,000 years old and older. Spanning from Antarctica to Greenland, the Mojave Desert to the Australian Outback, the result is a stunning and unique visual collection of ancient organisms unlike anything that has been created in the arts or sciences before, insightfully and accessibly narrated by Sussman along the way. Her work is both timeless and timely, and spans disciplines, continents, and millennia. It is underscored by an innate environmentalism and driven by Sussman’s relentless curiosity. She begins at “year zero,” and looks back from there, photographing the past in the present. These ancient individuals live on every continent and range from Greenlandic lichens that grow only one centimeter a century, to unique desert shrubs in Africa and South America, a predatory fungus in Oregon, Caribbean brain coral, to an 80,000-year-old colony of aspen in Utah. Sussman journeyed to Antarctica to photograph 5,500-year-old moss; Australia for stromatolites, primeval organisms tied to the oxygenation of the planet and the beginnings of life on Earth; and to Tasmania to capture a 43,600-year-old self-propagating shrub that’s the last individual of its kind. Her portraits reveal the living history of our planet—and what we stand to lose in the future. These ancient survivors have weathered millennia in some of the world’s most extreme environments, yet climate change and human encroachment have put many of them in danger. Two of her subjects have already met with untimely deaths by human hands. Alongside the photographs, Sussman relays fascinating – and sometimes harrowing – tales of her global adventures tracking down her subjects and shares insights from the scientists who research them. The oldest living things in the world are a record and celebration of the past, a call to action in the present, and a barometer of our future.
