and inhaled these items for one week. They expose the miscreant corporate giants who manufacture the toxins, the weak-kneed government officials who let it happen, and the effects on people across the globe; they also describe the extent to which we are poisoned, from the simple household dust that is polluting our blood to the toxins in our urine that are created by run-of-the-mill shampoos and toothpaste. c2009.By Jeffrey Kluger. 2008

demonstration of a device he had created in the attic of his family home near Bologna. It consisted of two wooden boxes, one of which could apparently transmit messages to the other. Many of those in the audience suspected that they were witnessing a mere conjuring trick. None can have guessed that Signor Marconi's magic box would be regarded as the most remarkable invention of the nineteenth century, and that he himself would become one of the most famous men in the world. 2003.By William Hinton. 1983

Presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part…
in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities. But, Zimmer writes, "Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are--our appearance, our height, our penchants--in inconceivably subtle ways." Heredity isn't just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors--using a word that once referred to kingdoms and estates--but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity really is. 2018.By Deborah Cadbury. 2004
