    Comparative Protozoology
    The protozoa are an eclectic assemblage of organisms encompassing a wide range of single-celled and multiple-celled colonial organisms lacking tissue organiza tion, but exhibiting remarkably refined biological behavior. In some modern classifications, they are classified as a subkingdom among the Protista (eukary otic single-celled organisms). Although they are not considered a formal cate gory by some taxonomists and some biologists consider the name inappropriate (inferring that they are the first unicellular animals, although some photosynthe size), it is still convenient to consider this group of organisms as an informal collection under the heading of protozoa. Their cosmopolitan distribution, sig nificant ecological role in mineral recycling and enhancement of carbon flow through lower trophic levels of food webs, and remarkable cellular adaptations to enhance survival in diverse environments make them significant organisms for biological investigation. In some cases, biologists are introduced to this group in first level courses or in invertebrate zoology, but never develop a full appreciation for the diverse and biologically sophisticated characteristics of these organisms. This book is intended as a survey of broad concepts in protozoan biology with an emphasis on comparative data. The focus is on the zoological aspects of the group. Topics more closely related to plantlike characteristics, as presented in books on phycol ogy, are not considered in detail here. A sound background in modern biology and an introduction to cellular biology will be helpful in understanding Chapters 15 and 16, which include a substantial amount of information on biochemistry.

    Amoeba Gives Clues to Animal Origins , Hörbuch, Digital, ungekürzt, 3min
    Scaling up from one cell too many may have been a small step rather than a giant leap for early life. A single-celled organism closely related to animals controls its life cycle using a molecular toolkit much like the one animals use to give their cells different roles, scientists report."Amoeba Gives Clues to Animal Origins" is from the November 12, 2016 issue of Science News. ungekürzt.

    The Cambrian Period: The History and Legacy of the Start of Complex Life on Earth , Hörbuch, Digital, ungekürzt, 91min
     Includes a bibliography for further listening Includes a table of contents  The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that Earth is around 4.6 billion years old, and the first four billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge. It’s unclear where they came from or even if they originated on this planet at all, but this gradual development continued until around four billion years ago when suddenly (in geological terms) more complex forms of life began to emerge. Scientists call this time of an explosion of new forms of life the Paleozoic Era, and it stretched from around 541-250 million years ago (Mya). In the oceans and then on land, new creatures and plants began to appear in bewildering variety, and by the end of this period, life on Earth had diversified into a myriad of complex forms that filled virtually every habitat and niche available in the seas and on the planet’s only continent, Pangea. Despite all of the scientific advances made in the past few centuries, including an enhanced understanding of Earth’s geological past, very little is known about the planet’s early history. It is generally accepted that the planet formed somewhere in the region of 4.5 billion years ago, and at some point, the first life appeared in the form of tiny, single-celled creatures, but scientists are unsure of what this life looked like. One of the problems for those seeking to trace the history of life on Earth is that modern scholars are almost entirely dependent on fossil records, but the earliest types of life left few fossils.

    How to Grow a Human: Adventures in Who We Are and How We Are Made , Hörbuch, Digital, ungekürzt, 734min
    A cutting-edge examination of what it means to be human and to have a 'self' in the face of new scientific developments in genetic editing, cloning and neural downloading.After seeing his own cells used to grow clumps of new neurons - essentially mini-brains - Philip Ball begins to examine the concepts of identity and consciousness. Delving into humanity's deep evolutionary past to look at how complex creatures like us emerged from single-celled life, he offers a new perspective on how humans think about ourselves. In an age when we are increasingly encouraged to regard the 'self' as an abstract sequence of genetic information, or as a pattern of neural activity that might be 'downloaded' to a computer, Ball returns us to the body - to flesh and blood - and anchor a conception of personhood in this unique and ephemeral mortal coil. How to Build a Human brings us back to ourselves - but in doing so, it challenges old preconceptions and values. It asks us to rethink how we exist in the world. ungekürzt. Language: English.

    The Compassionate Brain (eBook, ePUB)
    Here is the ultimate explanation of the brain for everyone who thinks: a guide to how the brain works, how our brains came to operate the way they do, and, most important, how to use your precious gray matter to its full capacity. The brain, according to current research, is not some kind of automatic machine that works independently of its user. In fact, the circuitry of the brain actually changes according to how one uses it. Our brains are continuously developing new capacities and refinements—or losing them, depending upon how we use them. Gerald Hüther takes us on a fascinating tour of the brain's development—from one-celled organisms to worms, moles, apes, and on to us humans—showing how we truly are what we think: our behavior directly affects our brain capacity. And the behavior that promotes the fullest development of the brain is behavior that balances emotion and intellect, dependence and autonomy, openness and focus, and ultimately expresses itself in such virtues as truthfulness, considerateness, sincerity, humility, and love. Hüther's user's-manual approach is humorous and engaging, with a minimum of technical language, yet the book's message is profound: the fundamental nature of our brains and nervous systems naturally leads to our continued growth in intelligence and humanity.

    Gravity , Hörbuch, Digital, ungekürzt, 655min
    Emma Watson, a brilliant research physician, has been training for years for the mission of a lifetime: to study living beings in space. Jack McCallum, Emma's estranged husband, has shared her dream of space travel, but a medical condition has grounded and embittered him. He must watch from the sidelines as his wife prepares for her first mission to the international Space Station. Once aboard the space station, however, things start to go terribly wrong. A culture of single-celled organisms known as Archaeons, gathered from the deep sea, are to be monitored in the microgravity of space. The true and lethal nature of this experiment has not been revealed to NASA. In space, the cells rapidly multiply and soon begin to infect the crew - with agonizing and deadly results. A recovery attempt ends in catastrophe: the NASA shuttle crashes, killing all onboard, and the space station is left dangerously crippled. Emma struggles to contain the deadly microbe, while back home, Jack and NASA work against the clock to retrieve Emma from space. But there will be no rescue. The contagion now threatens Earth's population as well, and the astronauts are left stranded in orbit, quarantined aboard the station - where they are dying one by one.... Written with an exacting eye, Dr. Tess Gerritsen ensnares the imagination with Gravity, her most steely, unforgettable thriller yet. ungekürzt. Language: English. Narrator: William Dufris.

    Minions: The Junior Novel , Hörbuch, Digital, ungekürzt, 111min
    The story of Universal Pictures and Illumination Entertainment's Minions begins at the dawn of time. Starting as single-celled yellow organisms, Minions evolve through the ages, perpetually serving the most despicable of masters. Continuously unsuccessful at keeping these masters - from T. rex to Napoleon - the Minions find themselves without someone to serve and fall into a deep depression. But one Minion named Kevin has a plan, and he - alongside teenage rebel Stuart and lovable little Bob - ventures out into the world to find a new evil boss for his brethren to follow. The trio embarks upon a thrilling journey that ultimately leads them to their next potential master, Scarlet Overkill (Academy Award® winner Sandra Bullock), the world's first-ever female supervillain. They travel from frigid Antarctica to 1960s New York City, ending in mod London, where they must face their biggest challenge to date: saving all of Minionkind...from annihilation. Featuring a soundtrack of hit music from the '60s that still permeates our culture today, Minions is produced by Illumination's Chris Meledandri and Janet Healy and is directed by Pierre Coffin and Kyle Balda. Brian Lynch has written the screenplay for the 3D-CG comedy adventure, and Chris Renaud serves as executive producer of the film. A retelling of the new feature film!

    Mitochondria and the Future of Medicine: The Key to Understanding Disease, Chronic Illness, Aging, and Life Itself , Hörbuch, Digital, ungekürzt, 438min
    The book has information for patients and practitioners on optimizing mitochondrial function for greater health and longevity.Why do we age? Why does cancer develop? What's the connection between heart failure and Alzheimer's disease or infertility and hearing loss? Can we extend lifespan, and if so, how? What is the exercise paradox? Why do antioxidant supplements sometimes do more harm than good? Many will be amazed to learn that all these questions, and many more, can be answered by a single point of discussion: mitochondria and bioenergetics.In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy. By understanding how our mitochondria work, in fact, it is possible to add years to our lives, and life to our years.Current research, however, has revealed a dark side: many seemingly disconnected degenerative diseases have tangled roots in dysfunctional mitochondria. However, modern research has also endowed us with the knowledge on how to optimize its function, which is of critical importance to our health and longevity. Lee Know offers cutting-edge information on supplementation and lifestyle changes for mitochondrial optimization, such as CoQ10, D-Ribose, cannabinoids, and ketogenic dietary therapy and how to implement their use successfully. Mitochondria and the Future of Medicine is an invaluable resource for practitioners interested in mitochondrial medicine and the true roots of chronic illness and disease as well as anyone interested in optimizing their health.PLEASE ungekürzt.
