Book Description
Substantial proportions of the genome of most eukaryotes, including those of metazoan parasites, are comprised of repetitive sequences. Mobile genetic elements (MGEs) constitute much of the repetitive component, particularly the interspersed sequences. This volume of nine chapters addresses MGEs that have colonized the genomes of medically important metazoan parasites and their vectors. These MGEs are parasites of parasites. These mobile elements are compared and contrasted with those from better-studied model organisms. The authors have included plentiful, relevant, and informative illustrations and references. Several chapters focus on mobile elements of the human schistosomes. Gerardo Ferbeyre focuses on the putative ribozyme activities on the SM alpha elements, SINE-like elements, including trans reactions catalyzed by these retroposons. Ricardo DeMarco and Sergio Verjovski-Almeida review the cut-and-paste transposons of schistosomes, including the Merlin and the SmTRC1 elements, and application of schistosome DNA transposons to transgenesis and mutagenesis. Claudia Copeland, Thewarach Laha and I review the retrovirus-like retrotransposons and non-long terminal repeat transposable elements of the schistosomes, including the Boudicca, fugitive and SR2 elements. Young-An Bae and Yoon Kong provide descriptions of retrotransposons from the human liver and lung flukes, Clonorchis sinensis and Paragonimus westermani, respectively, including the CsRn1 long terminal repeat retrotransposon. Continuing the investigations of MGEs of parasitic worms, Thewarach Laha, Alex Loukas and I summarize current knowledge of MGEs from hookworms, including details of the bandit and Transib transposons and dingo retrotransposons. Mobile elements in vectors of human parasites are also covered. Matty Knight and coauthors describe the nimbus retrotransposon and its discovery and other repetitive elements from the genome of the gastropod snail Biomphalaria glabrata, the intermediate host of Schistosoma mansoni. Zhijian Tu and Song Ti review MGEs of Anopheles mosquitoes, vectors of malaria, and other mosquitoes. They discuss practical uses of these MGEs. Craig Coates provides an expert article on transposon mediated transgenesis of mosquitoes, in particular dealing with his pioneering studies on the deployment of binary systems with the Mos1 mariner transposon. MGEs from the genomes of these metazoan parasites have practical uses in transgenesis and epidemiological studies and also are valuable for annotation of the genomes of these vectors and pathogens. These issues and future directions are well covered in these chapters.

Book Description
An argument that technology accelerates biological discovery, with case studies ranging from chromosome discovery with early microscopes to how DNA replicates using radioisotope labels. Engineering has been an essential collaborator in biological research and breakthroughs in biology are often enabled by technological advances. Decoding the double helix structure of DNA, for example, only became possible after significant advances in such technologies as X-ray diffraction and gel electrophoresis. Diagnosis and treatment of tuberculosis improved as new technologies—including the stethoscope, the microscope, and the X-ray—developed. These engineering breakthroughs take place away from the biology lab, and many years may elapse before the technology becomes available to biologists. In this book, David Lee argues for concurrent engineering—the convergence of engineering and biological research—as a means to accelerate the pace of biological discovery and its application to diagnosis and treatment. He presents extensive case studies and introduces a metric to measure the time between technological development and biological discovery. Investigating a series of major biological discoveries that range from pasteurization to electron microscopy, Lee finds that it took an average of forty years for the necessary technology to become available for laboratory use. Lee calls for new approaches to research and funding to encourage a tighter, more collaborative coupling of engineering and biology. Only then, he argues, will we see the rapid advances in the life sciences that are critically needed for life-saving diagnosis and treatment.

Book Description
The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?

Book Description
Josiah Sutton was convicted of rape. He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others -- arrest, swab, match, conviction. But there was just one problem -- Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of "stop and spit." DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness.

Book Description
Documents the remarkable mobility of DNA in procaryotic and eucaryotic genomes: the ability of various DNA segments to move to new sites, to invert, and to undergo deletion or amplification, generally without the extensive DNA sequence homology needed for classical recombination. Seventy contributors explore the mechanisms of these rearrangements, how they are regulated, their biological consequences, and their potential use as research tools. For students and researchers of molecular genetics. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
According to the modern version of Darwin's theory, DNA contains a program for embryo development that is passed down from generation to generation; the program is implemented by proteins encoded by the DNA, and accidental DNA mutations introduce changes in those proteins that natural selection then shapes into new species, organs and body plans. When scientists discovered forty years ago that about 98% of our DNA does not encode proteins, the non-protein-coding portion was labeled “junk” and attributed to molecular accidents that have accumulated in the course of evolution. Recent books by Richard Dawkins, Francis Collins and others have used this “junk DNA” as evidence for Darwinian evolution and evidence against intelligent design (since an intelligent designer would presumably not have filled our genome with so much garbage). But recent genome evidence shows that much of our non-protein-coding DNA performs essential biological functions. The Myth of Junk DNA is written for a general audience by biologist Jonathan Wells, author of Icons of Evolution. Citing some of the abundant evidence from recent genome projects, the book shows that “junk DNA” is not science, but myth.
