The human genome of three billion letters has been sequenced. So have the genomes of thousands of other organisms. With unprecedented resolution, modern technologies are allowing us to peek into the world of genes, biomolecules, and cells - and flooding us with data of immense complexity that we are just barely beginning to understand. A huge gap separates our knowledge of the components of a cell and what is known from our observations of its physiology. The authors have written this graduate textbook to explore what has been done to close this gap of understanding between the realms of molecules and biological processes. They have gathered together illustrative mechanisms and models of gene regulatory networks, DNA replication, the cell cycle, cell death, differentiation, cell senescence, and the abnormal state of cancer cells. The mechanisms are biomolecular in detail, and the models are mathematical in nature. The interdisciplinary presentation will be of interest to both biologists and mathematicians, and every discipline in between.
A geneticist and internationally recognized anti-racism educator provides a powerful, science-based rebuttal to common fallacies about human difference. Well-meaning physicians, parents, and even scientists today often spread misinformation about what biology can and can’t tell us about our bodies, minds, and identities. In this accessible, myth-busting book, geneticist Shoumita Dasgupta draws on the latest science to correct common misconceptions about how much of our social identities are actually based in genetics. Dasgupta weaves together history, current affairs, and cutting-edge science to break down how genetic concepts are misused and how we can approach scientific evidence in a socially responsible way. With a unifying and intersectional approach disentangling biology from bigotry, the book moves beyond race and gender to incorporate categories like sexual orientation, disability, and class. Where Biology Ends and Bias Begins is an invaluable, empowering resource for biologists, geneticists, science educators, and anyone working against bias in their community.
This important book addresses ways that K-12 leaders can develop and maintain partnerships with public health leaders and other community members during times of crises. Drawing on real practices of leaders and insights from public health professionals who helped bring children back into buildings during the COVID-19 pandemic, this book offers clear guidance on how to keep students safe, healthy, and learning during inevitable public health crises that impact K-12 schools. With a focus on building trust, a commitment to equity, and an emphasis on communication, this book highlights the building blocks for successful partnerships. This is a must-have playbook for K-12 leaders on how public health and education can effectively and efficiently partner to respond, recover, and prepare for future crises.
A bold new indictment of the racialization of science Decades of data cannot be ignored: African American adults are far more likely to develop Type 2 diabetes than white adults. But has science gone so far in racializing diabetes as to undermine the search for solutions? In a rousing indictment of the idea that notions of biological race should drive scientific inquiry, Sweetness in the Blood provides an ethnographic picture of biotechnology’s framings of Type 2 diabetes risk and race and, importantly, offers a critical examination of the assumptions behind the recruitment of African American and African-descent populations for Type 2 diabetes research. James Doucet-Battle begins with a h...
Histoplasma capsulatum is a dimorphic pathogenic fungus. In the soil, H. capsulatum grows in a mycelial form. When soil containing H. capsulatum is disturbed, mycelial fragments or conidia (vegetative-spores) become aerosolized. Once inhaled by a mammalian host, mycelial fragments and/or conidia convert into a yeast-like form. H. capsulatum yeast escape innate immune defenses and colonize host macrophages during infection. After the onset of adaptive immunity, activated macrophages produce the antimicrobial effector nitric oxide ( * NO) to restrict H. capsulatum replication. However, despite exposure to reactive nitrogen species (RNS), H. capsulatum is able to establish persistent infections...
