AIR IS NOT OXYGEN is a fun way to brush up on those essential science concepts you missed in school. (Admit it. You probably thought you had better things to do than study!) Clear, short chapters focus on mastering key concepts instead of memorizing facts. Dozens of optional hands-on activites make science come alive! (Feel free to kill it afterwards.) In a style described as “Dave Barry meets Bill Nye with a touch of the Mythbusters,” award-winning author, Bill Morelan, debunks common misconceptions about basic science. Based on both the National Science Content Standards and the Next Generation Science Standards, AIR IS NOT OXYGEN covers Life Science, Earth Science, Physical Science, and Science Methods.A fun, informative read, AIR IS NOT OXYGEN helps fill the gaps in your science education. (You'll never be humiliated by science geeks again!) Perfect for sharing, or as a handy basic reference tool. Makes a great book for kids, too.

This Very Short Introduction is an exciting and non-traditional approach to understanding the terminology, properties, and classification of chemical elements. It traces the history and cultural impact of the elements on humankind from ancient times through today. Packed with anecdotes, The Elements is a highly engaging and entertaining exploration of the fundamental question: what is the world made from?

The remarkable scientific story of how Earth became an oxygenated planet The air we breathe is twenty-one percent oxygen, an amount higher than on any other known world. While we may take our air for granted, Earth was not always an oxygenated planet. How did it become this way? Donald Canfield—one of the world's leading authorities on geochemistry, earth history, and the early oceans—covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of the Earth. Canfield guides readers through the various lines of scientific evidence, considers some of the wrong turns and dead ends along the way, and highlights the scientists and researchers who have made key discoveries in the field. Showing how Earth’s atmosphere developed over time, Oxygen takes readers on a remarkable journey through the history of the oxygenation of our planet.

A phenomenon known as crustal displacement shifts the Earth's crust, repositioning continents and causing countless deaths. In the wake of the global catastrophe, the world struggles to take care of its displaced billions. But Antarctica, freshly thawed and blooming, has emerged as a new hope. Rather than wage a world war no nation can endure, the leading nations devise a competition, a race to the center of Antarctica, with the three victors dividing the continent. It is within this race that Mirabelle Whitney, one of the few surviving experts on the continent, grouped with an American special forces unit, finds herself. But the dangers awaiting the team are far worse than feared; beyond the sour history of a torn family, beyond the nefarious intentions of their human enemies, beyond the ancient creatures reborn through anhydrobiosisthere are the Nephilim.

Oxygen offers fresh perspectives on our own lives and deaths, explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas, following chains of evidence, the book ranges through many disciplines, from environmental sciences to molecular medicine. Damage to DNA caused by oxidative stress appears to explain aging and many of its diseases, hence the popularity in alternative health circles of antioxidants. But antioxidants alone fail to prevent aging. Lane suggests two different avenues of study: modulation of the immune system, which generates free radicals as part of its defense against infectious diseases; and ways of improving the health of our cellular mitochondria, on which many age-related ailments seem to depend. Provocative and complexly argued. Copyright ©Kirkus Reviews, used with permission.

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
