Since the beginnings of conscious thought, human beings have looked with wonder at the world around them. Perhaps the most significant part of the development of consciousness was self-awareness, and with it came the profoundest of biological questions: “Where did I come from?”.
The Coiled Spring starts with the most fundamental of premises in modern developmental biology: All cells contain the same genetic information. He then logically progresses to ask, if this is so, why all cells in the body are not the same. The rest of the book (and indeed embryogenesis) answers this question.
Connect content-area literacy and science with differentiated readers featuring lab activities and profiles of related scientitists. Anton van Leeuwenhoek was not educated in science, but he created the best microscopes of the 17th century. He made more than 400 microscopes and used them to study living organisms. British scientist Robert Hooke was the first scientist to observe cells and give them their name. Many scientists are still making discoveries in the areas of genetics and stem cell research.

British scientist Robert Hooke built an early microscope and was the first scientist to observe cells and give them their name. Anton van Leeuwenhoek created the best microscopes of his time and used them to study living organisms. Matthias Schleiden, Theodor Schwann, and Rudolf Virchow created Cell Theory, which says that all living things are made of cells; cells are the smallest part of a living thing; and all cells come from other cells.
A thorough yet concise account of cancer biology, this book emphasizes the cellular and molecular mechanisms involved in the transformation of normal into malignant cells, the invasiveness of cancer cells into host tissues, and the metastatic spread of cancer cells in the host organism. It also defines the fundamental pathophysiological changes that occur in tumor tissue and in the host animal or patient. The approach throughout the book is to discuss the historical development of a field, citing the key experimental advances to the present day,
