Product Description
In a narrative that combines cutting-edge science with intense physical adventure, Dark Life tells the fascinating story of the quest to find life far underground and deep in space. Able to thrive without sunlight or oxygen, dark life is a mass of subterranean bacteria that would likely tip the scale if weighed against all other living matter combined. Journalist Michael Ray Taylor takes us from Antarctic lakes to Hawaiian volcanoes to the satellites of Jupiter in search of these mysterious underground creatures that are redefining our understanding of evolution. Taylor serves as a field assistant on several key scientific expeditions. He descends deep into New Mexico's tortuous Lechuguilla Cave and focuses powerful NASA microscopes on never-before-seen life-forms. He accompanies a young NASA intern who unknowingly kicks off a raging international scientific debate when she uncovers traces of dark life in a rock extracted from nearly two miles below Washington State -- traces that appear identical to the "micro-fossils" found in a Martian meteorite. He meets another scientist who has staked his reputation on using dark life to generate a cure for breast cancer. Throughout his adventures, Taylor gains unique insight into a growing controversy about the very definition of life itself -- an issue that scientists had long ago considered settled. Whether he is exploring the structures of a mysterious cell or reconnoitering tropical caves, Michael Ray Taylor is an adventurer for the new millennium.

Amazon.com Review
The microbes that caver Michael Ray Taylor calls "dark life" are found deep in the earth, in boiling oceanic vents, Antarctic ice, and lots of other places far from the reach of the sun's energy. These "extremophiles" are energy opportunists, subsisting on chemicals, radioactivity, or the faint light of molten rock. The study of these organisms is quite new, and scientists are learning that examining them may provide hints about the possibility of extraterrestrial life. Dark Life is a first-person tour of the places Taylor has looked for archaebacteria and other strange microorganisms--Lechuguilla Cave in New Mexico, the hot springs of Viterbo in central Italy, NASA laboratories, and the halls of academia. Taylor met with passionate scientists searching for answers about how things can live deep in the earth and if they can survive in the unimaginable cold of outer space while hitchhiking on meteors. Dark Life chronicles the triumphs and disappointments of this new field of science with engaging and personal stories. The steady but frustrating progress of science is never more apparent than in the passages relating to the rise and fall of ALH84001. The potato-sized meteorite from Mars (and the scientists who analyzed it) enjoyed brief but frenzied attention when it was announced that microscopic forms in the rock may have indicated the presence of nanobacteria. But if you're expecting resolution to this question in Dark Life, be warned: to Taylor, it's the journey that's most exciting. --Therese Littleton

Entertaining and Informative by Victoria Butler (El Paso, TX)

Michael Taylor writes a fantastic narrative non-fiction account of mid 1990's events involving discoveries in the fields of microbiology, evolution, astrobiology, and biogeochemistry. His narritive is smooth and entertaining, and he includes enough science to appropriately validate his claims. Though the idea of a three-branched tree of life on Earth is rather old, Taylor gives great insight into the idea for the regular person. While most biology classes contain some reference to nanobacteria and extremophiles, the extent of their populations may be misrepresented in some textbooks. His accounts of cave exporations were most fascinating, as are the colorful discriptions of well known scientists.

Politics, personalities, and science of the dark world by Tim F. Martin (Madison, AL United States)

_Dark Life_ by Michael Ray Taylor was a very interesting book. The author began it writing as a science journalist - having written a previous book on cave exploration as well has having articles published in such magazines as _Audubon_ - but over the course of the two and a half years he worked on this book went from becoming an observer to an active participant, a point he himself made several times in amazement and wonder. Originally he had set out to chronicle what was known about "dark life," microorganisms that dwell far underground or in the deep sea, organisms that derive their nourishment from sources independent of sunlight. These organisms, which have been found in such varied places as salt domes, Antarctic ice cores, and in highly acidic caves, have continually challenged notions of what life can tolerate, organisms so common that they may outnumber surface organisms (indeed Taylor rejected the commonly used term "extremophile" as he believes the term implies that these organisms are a "rare curiosity"). Taylor wrote of the history of the search for these microbes, the personalities involved, and where current research was in the field (as well as possible applications of this research). Somewhere along the way he became part of the story, as he became the friend and later colleague of several of the researchers he covered. While not a trained scientist per se, at least not in the field of microbiology, he assisted in and even proposed a number of experiments in the search for controversial nanobacteria (microbes with a size of less than 0.2 micrometers, once thought to be too small to be an independent functioning organism or at least too small for a prokaryotic organism, including known bacteria and archaea; not a virus) in a variety of environments, mostly notably Hot Springs National Park in Arkansas. By the end of the book he was regularly exchanging email with researchers, providing samples for them, and even had co-authored a few presentations at various seminars. Much of the book is focused on personalities - understandable given Taylor's increasing personal involvement in the story himself - though mainly in the context of research on the topic at hand. The main characters (if you will) in the book were Larry Mallory (a scientist who had devoted his career to harvesting and culturing cave microbes in a promising search for a cure for cancer, particularly from microbes from the fascinating Lechuguilla Cave in New Mexico, an interesting place described in great detail in the book), Bob Folk (a colorful scientist who discovered nanobacteria and their presence in a number of substances and had been in the lead in efforts to prove that microorganisms are vital in the formation of travertine in caves and hot springs as well as in some cases at least entire caves and cave systems), and Anne Taunton (an undergraduate student who as part of a NASA internship became embroiled in the efforts to determine whether or not the famed Martian meteorite ALH 84001 contained fossils of extraterrestrial nanobacteria). Others are followed to lesser degrees, among them Finnish nanobacteria expert E. Olavi Kajander, who had done pioneer work showing that nanobacteria may be the possible agents of many maladies such as kidney stones, Alzheimer's, and Mad Cow Disease that involve mineral precipitation in the body. In large measure these and other personalities faced considerable skepticism, criticism, and worse in their studies, as scientists found it hard to accept (in different instances) what was thought of as "impossibly" small bacteria, biological origins for various types of minerals and mineral formations, and the presence of microfossils in ALH 84001. Mallory had to leave his university because he was essentially denied tenure, the administration not believing his study of cave microorganisms important, Folk faced considerable criticism for suggesting that such substances as travertine owed their origins to bacteria, and Taunton (and the team she worked with) had a very difficult time with several scientists - including even her own undergraduate academic advisor - over efforts to demonstrate that the ALH 84001 microfossils were evidence of Martian life or even life of any kind. Although Taylor did a good job of showing the fact there was sometimes intense and even rather personal criticism in science, I don't know if he always showed why people had such a hard time accepting bold new theories. In particular some of the opposition to ALH 84001 fossils was quite heated. Though much of the focus was on personalities, politics, and the process of research the microbes were much discussed as well, many with bizarre biologies. Some cold-loving organisms were termed "psychrophiles," capable of growth below freezing, at -5 degrees Celsius, organisms that exhibit slower metabolisms at temperatures above freezing and death at anything approaching human body temperature (organisms that for years - like many other examples of dark life - proved difficult to study and culture in the lab). Some organisms found in apparently solid rock two miles deep, existing only on hydrogen and water, have unbelievably slow metabolisms, appearing to divide cells no more than once per century. Though many caves and indeed individual pools in caves produced unique microorganisms there were also astonishing similarities; the closest relatives to some sulfur-oxidizing thermophilic (heat-loving) bacteria from a cave in Kentucky were found to be a sulfur-oxidizing, symbiotic bacterium from a deep sea polychaeta worm, a relationship that has not yet been explained. At least as far as this reader is concerned Taylor made his case that nanobacteria exist, that they are key in the formation of some minerals and many caves, and I am very open to the idea that ALH 84001 may indeed contain Martian microfossils. I enjoyed reading about the discussions scientists had about whether or not subsurface Antarctic lakes such as Lake Vostok and Jovian moon of Europa might have dark life and hope that both can be analyzed in the not too distant future.

For starters I will never look at my mineral collection quite the same again. Dark Life has shown that nanobacteria (only recently confirmed)is the absolute frontier of a new world. Minerals and "life" coexist and the nanobacteria "feed" upon the chemical compositions of minerals. The scientific world will be turned on its' head in the near future as a whole new science emerges. This book is easy to understand for those of us who aren't scientits but who are interested. As one who also has Multiple Sclerosis the possible connection with nanobacteria and mineral plaques in the brain was astounding as I read it.

Damn interesting, heavy on the human drama

I read this book after buying on a discout shelf in some clearance book seller. It was a pleasant surprise. It, as I wrote in the title, a little heavy on human drama and soap operatic themes. The science behind it is absolutely interesting and has spurred me to read further on the topic of nanobacteria. This is a great starting out book, but not a great book for those reading for the science of it.

Nanobacteria, A New Form of Life and Its Pathology in Humans by Gary S. Mezo, President, Academy of Medical NanoScience (USA)

Nanobacteria have been researched by many prominent scientists worldwide. This book looks at the findings of scientists with respect to Nanobacteria and the science of Geology. Nanobacteria, specifically Nanobacterium Sanguineum, have been studied by scientists and medical researchers as they pertain to causing human disease or Pathology as well. Nanobacterium Sanguineum is a Nanobacteria that is approximately 10,000 times smaller than regular bacteria. It replicates from 1000 to 10,000 times slower than regular bacteria as well. It grows in the human system in blood, and has been found by various medical researchers and scientists to cause many human problems. Some of the various diseases that it has either been implicated to be involved with or to cause are: Calcification in atherosclerotic plaque, kidney stones, calcification in the lenses of eyes that ultimately causes "cataracts", soft tissue calcification in scleroderma, calcification in tumors, calcification in arthritis or osteoarthritis and other pathological disease states in humans. These Nanobacteria colonize and secrete a "biofilm" over themselves that causes them to be covered by a calcium "shell". These Nanobacteria are implicated to be the cause of all calcification in the human system that you were not born with, that you subsequently develop as you age. These Nanobacteria are also implicated in causing some forms of cancer and "apoptosis" or cell death. Scientists are now working on ways to eradicate Nanobacterium Sanguineum with prescription medications. Please keep your eyes open for further research regarding Nanobacteria. Try surfing on the web for "nanobacteria". Sincerely, Gary S. Mezo, President of the Academy of Medical NanoScience, Tel:813-264-2241.
