Gods Providential Work in Creation Before Life Began God has been present and active in creation from the moment he created it ex nihilo. Few Christians would question this claim, but its implications for ongoing theology and science dialogues have not been fully explored.In this pathbreaking and field-advancing work, Ross Hastings brings his expertise in both scientific and theological disciplines to bear on the topic of divine providence in chemical evolution. Based on the latest research in the developing field of chemical evolution and the work of theological giants such as Karl Barth, Hastings shows how God may have been providentially and non-competitively at work in the process by which simple prebiotic molecules gave rise to the complex molecules in the first living organisms.In God and Molecules, Hastings provides cutting-edge theological engagement with the developing scientific field of chemical evolution, advances the discussion in theology and science with this new integrative work, and offers a holistic alternative for thinking about chemical evolution that overcomes the binary of theology versus science. God and Molecules pushes toward new frontiers in theology and science and casts a compelling, integrative, and ultimately healing vision for how God has been lovingly involved in the developmental process of the earliest life on earth.

Among all the varied productions with which Nature has adorned the surfaces of the earth, none awakens our sympathies, or interests our imagination so powerfully as those venerable trees, which seem to have stood the lapse of ages John Muir, 1868A fascinating celebration of the some of the oldest living organisms on the planet, from the grand Oaks of Europe and mighty Redwoods of California to Africas upside-down Baobab tree, and from the Ginkgos of China and Korea to the Olive tree, the worldwide symbol of peace.Ancient Trees covers those species of tree that have lived for more than a thousand years: the Redwood, Bristlecone pine, Montezuma Cypress, the Monkey Puzzle, Amazonian Ancients, Yew, Oak, Sweet Chestnut, Lime, Olive, Welwitschia, the Baobab, Kauri, Totara, Antarctic Beech, the Fig, Cedar, and Ginkgo.Anna Lewington, the well-known writer on all things botanical, and leading wildlife photographer Edward Parker provide an illuminating and visually striking history of each tree species, including where the long-living species can still be found, the trees botanical details, and its mythical associations.

Un premio nobel y un astrofísico superventas unen sus fuerzas para descubrir cómo el universo insufló vida a la materia. Durante más de un siglo, los orígenes y la expansión de la vida en la Tierra han permanecido envueltos en un halo de misterio. En Vida y cosmos, Mario Livio y Jack Szostak nos muestran como nuevos descubrimientos y tecnologias estan generando un progreso cientifico inaudito para resolver estas cuestiones. A traves de la vision panoramica que ofrece la astrobiologia, un campo multidisciplinario y vanguardista que fusiona biologia, quimica, astronomia y otras ramas, los autores nos sumergen de una forma fluida y profunda en el conocimiento actual sobre el origen de la vida en la Tierra. Una exploracion decisiva sobre si la vida es un accidente fortuito o un imperativo quimico.
