A World on Fire
by Joe JacksonThe discovery of oxygen in the late 1700s changed human thought & history radically. Yet its discovery began quietly, with the survival of a mouse under a lab. bell jar. This re-creation of these events takes us back to the final decades of the 1700s & the waning days of the Enlightenment. The English heretic & the French aristocrat who simultaneously isolated oxygen could not have been an unlikelier pair. Joseph Priestley was a tinkerer who knew Ben Franklin, John Adams, & Thomas Jefferson, to whose new nation he eventually fled. Antoine Lavoisier was rich & sophisticated, yet his path ended at the guillotine. Both Priestley & Lavoisier would see their works & lives destroyed, & never know how profoundly they changed the future. Illustrations.
A World on the Wing: The Global Odyssey Of Migratory Birds
by Scott WeidensaulNew York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.
A World to Live In
by George M. WoodwellA century of industrial development is the briefest of moments in the half billion years of the earth's evolution. And yet our current era has brought greater changes to the earth than any period in human history. The biosphere, the globe's life-giving envelope of air and climate, has been changed irreparably. In A World to Live In, the distinguished ecologist George Woodwell shows that the biosphere is now a global human protectorate and that its integrity of structure and function are tied closely to the human future. The earth is a living system, Woodwell explains, and its stability is threatened by human disruption. Industry dumps its waste globally and makes a profit from it, invading the global commons; corporate interests overpower weak or nonexistent governmental protection to plunder the planet. The fossil fuels industry offers the most dramatic example of environmental destruction, disseminating the heat-trapping gases that are now warming the earth and changing the climate forever. The assumption that we can continue to use fossil fuels and "adapt" to climate disruption, Woodwell argues, is a ticket to catastrophe.But Woodwell points the way toward a solution. We must respect the full range of life on earth -- not species alone, but their natural communities of plant and animal life that have built, and still maintain, the biosphere. We must recognize that the earth's living systems are our heritage and that the preservation of the integrity of a finite biosphere is a necessity and an inviolable human right.

A Year Like No Other: How a Global Pandemic Led to Vanderbilt University's Proudest Moment
by Ryan UnderwoodThe University that was at the heart of the research to discover the vaccines for the pandemic pens the story of how it all happened.In 2020, as COVID-19 threw the U.S. higher education system into turmoil, university administrators around the country debated whether it was prudent—or even possible—to teach students in person or conduct laboratory research amid a once-in-a-century pandemic. For the leadership at Vanderbilt University, the answer to the question was a resounding Yes. Viewing residential education and collaborative research as essential to its academic and societal mission, Vanderbilt was one of a small number of America&’s top universities to put rigorous safety protocols in place to allow students, faculty, and research personnel back to campus in the fall. Told with recollections and insights from Vanderbilt&’s leaders, students, faculty, and staff, and moving at a pace matching the events it describes, A Year Like No Other takes readers from Vanderbilt&’s near-shutdown in the spring through its reopening for the 2020–2021 academic year, providing an inside look at how the university coped not only with COVID-19, but also with a tragic night of tornadoes and the urgent calls for racial justice following the killing of George Floyd. A Year Like No Other also highlights some of the vital contributions that faculty at Vanderbilt and Vanderbilt University Medical Center have made to the development of COVID-19 vaccines and therapies, with research fueled in part by Dolly Parton, the beloved country music legend. A Year Like No Other captures a singular moment in the university&’s history while delivering a concise portrait of successful crisis management playing out amid the fast-changing circumstances of global health threats and a barrage of local hardships.
A Year with Nature: An Almanac
by Marty Crump Bronwyn McIvorA Year with Nature is an almanac like none you’ve ever seen: combining science and aesthetics, it is a daily affirmation of the extraordinary richness of biodiversity and our enduring beguilement by its beauty. With a text by herpetologist and natural history writer Marty Crump and a cornucopia of original illustrations by Bronwyn McIvor, this quirky quotidian reverie gazes across the globe, media, and time as it celebrates date-appropriate natural topics ranging from the founding of the National Park Service to annual strawberry, garlic, shrimp, hummingbird, and black bear festivals. With Crump, we mark the publication of classics like Carson’s Silent Spring and White’s Charlotte’s Web, and even the musical premiere of Tchaikovsky’s Swan Lake. We note the discovery of the structure of DNA and the mountain gorilla, the rise of citizen science projects, and the work of people who’ve shaped how we view and protect nature—from Aristotle to E. O. Wilson. Some days feature US celebrations, like National Poinsettia Day and National Cat Day; others highlight country-specific celebrations, like Australia’s Wombat Day and Thailand’s Monkey Buffet Festival, during which thousands of macaques feast on an ornately arranged spread of fruits and vegetables. Crump also highlights celebrations that span borders, from World Wildlife Conservation Day to International Mountain Day and global festivities for snakes, sea turtles, and chocolate. Interweaving fascinating facts on everything from jellyfish bodies to monthly birth flowers with folkloric entries featuring the Loch Ness Monster, unicorns, and ancient Greek, Roman, and Egyptian mythology, the almanac is as exhaustive as it is enchanting. A Year with Nature celebrates the wonder and beauty of our natural world as we have expressed it in visual arts, music, literature, science, natural history, and everyday experience. But more than this, the almanac’s vignettes encourage us to contemplate how we can help ensure that future generations will be able to enjoy the landscapes and rich biodiversity we so deeply cherish.

ABC Transporters - 40 Years on: 40 Years On
by Anthony M. GeorgeThis book provides new structural, biochemical, and clinical information on ABC transporters. The authors explore and describe the state of the art of research, knowledge, and prospects for the future for this important family of proteins. The first ABC transporter was discovered in 1973 and was named P-glycoprotein. It elicits resistance to cytotoxic drugs, chiefly in human tumours, within which chemotherapy failure is observed in about 50% of cases. Together with its complex pharmacology, and even a suspected role in Alzheimer's disease, this ABC transporter still eludes a clinical solution to its multidrug resistance property. ABC transporters are integral membrane active proteins and they belong to one of the largest protein families across all species. Their myriad roles encompass the import or export of a diverse range of allocrites, including ion, nutrients, peptides, polysaccharides, lipids, and xenobiotics. They are of major medical importance with many members elaborating multidrug resistance in bacteria, fungi, yeast, parasites, and humans. Other ABC transporters are involved in a number of inherited diseases, including cystic fibrosis, macular degeneration, gout, and several other metabolic disorders

AC/DC
by Tom McnicholAC/DC tells the little-known story of how Thomas Edison wrongly bet in the fierce war between supporters of alternating current and direct current. The savagery of this electrical battle can hardly be imagined today. The showdown between AC and DC began as a rather straightforward conflict between technical standards, a battle of competing methods to deliver essentially the same product, electricity. But the skirmish soon metastasized into something bigger and darker. In the AC/DC battle, the worst aspects of human nature somehow got caught up in the wires; a silent, deadly flow of arrogance, vanity, and cruelty. Following the path of least resistance, the war of currents soon settled around that most primal of human emotions: fear. AC/DC serves as an object lesson in bad business strategy and poor decision making. Edison's inability to see his mistake was a key factor in his loss of control over the ?operating system? for his future inventions?not to mention the company he founded, General Electric.
ACCESS TO RESEARCH DATA IN THE 21ST CENTURY: An Ongoing Dialogue Among Interested Parties Report of a Workshop
by Science Technology Law PanelIn the years since the Shelby Amendment, scientists, industry, and policy makers have struggled over how the public’s new right of access should be applied to scientific data. There is loose agreement that research data should be accessible, but wide disagreement over the “depth” to which the public has such a right. The National Academies’ Science, Technology, and Law Program held a workshop to explore the mounting tensions in the federal regulatory process between the need to provide access to research data and the need to protect the integrity of the research process. The workshop provided a picture of the debate arising from passage of the Shelby Amendment and the resulting OMB revisions of Circular A-110. This report is a summary of the workshop.

ACRP Report 63: Measurement of Gaseous HAP Emissions from Idling Aircraft as a Function of Engine and Ambient Conditions
by Transportation Research BoardThe findings of this project are summarized as follows:<P><P> 1. Temperature dependence: VOC emission indices are approximately twice as high under cold conditions (-8°C to 0°C) as they are at 15°C for the CFM56-7B24.<P> 2. Fuel flow rate dependence: For the engine states that are likely to be most representative of the operational aircraft taxiway engine state, the VOC emission indices for the CFM56-7B24 are approximately 40% greater than the ICAO certification engine state (7% thrust).<P> 3. VOC speciation: The composition profile of the exhaust is constant. The ratios of individual VOCs (e.g., formaldehyde to 1,3-butadiene) remain constant over all thrust settings and temperatures encountered. The first two findings are thus expected to be applicable to all VOCs measured, with the exception that there is a dependence of benzene emissions on fuel aromatic content.
