Synopsis

Polar Night explores the phenomenon of prolonged darkness in the Arctic and Antarctic, revealing its profound impact on polar ecosystems, wildlife adaptations, and human settlements. This seasonal event, lasting weeks or months, challenges life in unique ways, from disrupting circadian rhythms to influencing migration patterns. Understanding the polar night is crucial, especially considering the effects of climate change on these sensitive environments.

 
The book delves into the science behind the polar night, differentiating between types of twilight and examining the physiological and behavioral adaptations of polar fauna. For instance, some animals modify their feeding strategies, while others rely on specialized sensory adaptations to navigate the darkness. Human settlements in the Arctic also face challenges, including seasonal affective disorder, prompting adaptations in architecture and cultural practices.

 
Furthermore, the book highlights the hurdles faced by scientific research during the polar night, detailing how researchers employ specialized equipment and innovative techniques to study the atmosphere, ice, and ocean in extreme conditions. By drawing from peer-reviewed publications, firsthand accounts, and interdisciplinary research, Polar Night offers a comprehensive view of this frequently overlooked aspect of polar science, progressing from astronomical principles to the ecological and social impacts of prolonged darkness.

    The first full-length history of biomedical research with human subjects in the period "before Tuskegee"—from 1890 to 1940 
     
     
     
    Long before the U.S. government began conducting secret radiation and germ-warfare experiments, and long before the Tuskegee syphilis experiments, medical professionals had introduced—and hotly debated the ethics of—the use of human subjects in medical experiments. In Subjected to Science, Susan Lederer provides the first full-length history of biomedical research with human subjects in the earlier period, from 1890 to 1940. 
     
     
     
    Lederer offers detailed accounts of experiments—benign and otherwise—conducted on both healthy and unhealthy men, women, and children, including the yellow fever experiments (which ultimately became the subject of a Broadway play and Hollywood film), Udo Wile's "dental drill" experiments on insane patients, and Hideyo Noguchi's syphilis experiments, which involved injecting a number of healthy children and adults with the syphilis germ, luetin.

    In the beginning, the universe was nothing more than a dense singularity—silent, timeless, and still. Then came the Big Bang, a colossal eruption that scattered matter and energy in every direction. From this explosion, light was born. It was the first visible sign of creation, a brilliant flash that broke the void and ignited the formation of stars, galaxies, and eventually life. Light traveled fast, racing across the empty stretches of the newborn cosmos. It became the symbol of birth and beginning, of knowledge and awareness. Without light, the universe would remain unseen and unknown, a place without structure or story. 
    But where there is light, there must also be darkness. Darkness is not just the absence of light—it is its counterpart. It filled the vast spaces between stars and galaxies, the silent shadows where light couldn’t reach. In many ways, darkness defines the boundaries of light, giving it contrast and shape. Without the dark, light would have no form. As stars began to shine and galaxies spun into form, so did the shadows. Black holes, vast voids, and mysterious dark matter began to shape the cosmic landscape. Darkness became more than empty space; it became a force of its own, influencing the movement of galaxies and the very structure of the universe. 
    The birth of stars played a crucial role in this balance. When matter began to clump together under gravity, stars ignited through nuclear fusion. These glowing spheres of heat and light pierced the darkness, scattering energy into the cosmos. But every star also cast shadows, created contrast, and eventually faded back into darkness when their fuel was spent. Supernovae, neutron stars, and black holes emerged from the deaths of stars, returning their light to the cosmic dark. This cycle of creation and destruction shows how light and darkness are deeply connected—each one gives rise to the other.

    Triumphs and disasters in the deep sea 
    This is a journey through time and water, to the bottom of the ocean and the future of our planet. 
    We do not see the ocean when we look at the water that blankets more than two thirds of our planet. We only see the entrance to it. Beyond that entrance is a world hostile to humans, yet critical to our survival. The first divers to enter that world held their breath and splashed beneath the surface, often clutching rocks to pull them down. Over centuries, they invented wooden diving bells, clumsy diving suits, and unwieldy contraptions in attempts to go deeper and stay longer. But each advance was fraught with danger, as the intruders had to survive the crushing weight of water, or the deadly physiological effects of breathing compressed air. The vertical odyssey continued when explorers squeezed into heavy steel balls dangling on cables, or slung beneath floats filled with flammable gasoline. Plunging into the narrow trenches between the tectonic plates of the Earth’s crust, they eventually reached the bottom of the ocean in the same decade that men first walked on the moon. 
    Today, as nations scramble to exploit the resources of the ocean floor, The Frontier Below recalls a story of human endeavour that took 2,000 years to travel seven miles, then investigates how we will explore the ocean in the future. 
    Meticulously researched and drawing extensively on unpublished sources and personal interviews, The Frontier Below is the untold story of the pioneers who had the right stuff, but were forgotten because they went in the wrong direction. 
    The Frontier Below by Jeff Maynard is a captivating journey through the history of maritime expeditions, the science of physiology, and the economics of resource extraction. It is a testament to human endeavour and the indomitable spirit of exploration, offering a glimpse into the future of our oceans. 
    For fans of Julian Sancton (Madhouse at the End of the Earth), Buddy Levy (Empire of Ice and Stone), Rachel Lance (In the Waves), James Bradley (Ghost Species), and Helen Czerski (Blue Machine).
