The enormous recent success of molecular developmental biology has yielded a vast amount of new information on the details of development. So much so that we risk losing sight of the underlying principles that apply to all development. To cut through this thicket, John Tyler Bonner ponders a moment in evolution when development was at its most basic--the moment when signaling between cells began. Although multicellularity arose numerous times, most of those events happened many millions of years ago. Many of the details of development that we see today, even in simple organisms, accrued over a long evolutionary timeline, and the initial events are obscured. The relatively uncomplicated and easy-to-grow cellular slime molds offer a unique opportunity to analyze development at a primitive stage and perhaps gain insight into how early multicellular development might have started. Through slime molds, Bonner seeks a picture of the first elements of communication between cells. He asks what we have learned by looking at their developmental biology, including recent advances in our molecular understanding of the process. He then asks what is the most elementary way that polarity and pattern formation can be achieved. To find the answer, he uses models, including mathematical ones, to generate insights into how cell-to-cell cooperation might have originated. Students and scholars in the blossoming field of the evolution of development, as well as evolutionary biologists generally, will be interested in what Bonner has to say about the origins of multicellular development--and thus of the astounding biological complexity we now observe--and how best to study it.

Brian Skyrms offers a fascinating demonstration of how fundamental signals are to our world. He uses various scientific tools to investigate how meaning and communication develop. Signals operate in networks of senders and receivers at all levels of life, transmitting and processing information. That is how humans and animals think and interact.

In this book the author, an investigative journalist, traces the social history of marijuana from its origins to its emergence in the 1960s as a defining force in an ongoing culture war. He describes how the illicit marijuana subculture overcame government opposition and morphed into a multibillion-dollar industry. In 1996, Californians voted to legalize marijuana for medicinal purposes. Similar laws have followed in several other states, but not without antagonistic responses from federal, state, and local law enforcement. The author draws attention to underreported scientific breakthroughs that are reshaping the therapeutic landscape: medical researchers have developed promising treatments for cancer, heart disease, Alzheimer's, diabetes, chronic pain, and many other conditions that are beyond the reach of conventional cures. This book is an examination of the medical, recreational, scientific, and economic dimensions of the world's most controversial plant.

First demonstrated in 1928, color television remained little more than a novelty for decades as the industry struggled with the considerable technical, regulatory, commercial, and cultural complications posed by the medium. Only fully adopted by all three networks in the 1960s, color television was imagined as a new way of seeing that was distinct from both monochrome television and other forms of color media. It also inspired compelling popular, scientific, and industry conversations about the use and meaning of color and its effects on emotions, vision, and desire. In Bright Signals Susan Murray traces these wide-ranging debates within and beyond the television industry, positioning the story of color television, which was replete with false starts, failure, and ingenuity, as central to the broader history of twentieth-century visual culture. In so doing, she shows how color television disrupted and reframed the very idea of television while it simultaneously revealed the tensions about technology's relationship to consumerism, human sight, and the natural world.

How understanding the signaling within social networks can change the way we make decisions, work with others, and manage organizations. How can you know when someone is bluffing? Paying attention? Genuinely interested? The answer, writes Alex Pentland in Honest Signals, is that subtle patterns in how we interact with other people reveal our attitudes toward them. These unconscious social signals are not just a back channel or a complement to our conscious language; they form a separate communication network. Biologically based “honest signaling,” evolved from ancient primate signaling mechanisms, offers an unmatched window into our intentions, goals, and values. If we understand this ancient channel of communication, Pentland claims, we can accurately predict the outcomes of situations ranging from job interviews to first dates. Pentland, an MIT professor, has used a specially designed digital sensor worn like an ID badge—a “sociometer”—to monitor and analyze the back-and-forth patterns of signaling among groups of people. He and his researchers found that this second channel of communication, revolving not around words but around social relations, profoundly influences major decisions in our lives—even though we are largely unaware of it. Pentland presents the scientific background necessary for understanding this form of communication, applies it to examples of group behavior in real organizations, and shows how by “reading” our social networks we can become more successful at pitching an idea, getting a job, or closing a deal. Using this “network intelligence” theory of social signaling, Pentland describes how we can harness the intelligence of our social network to become better managers, workers, and communicators.

A unified treatment of the generation and analysis of brain-generated electromagnetic fields. In Brain Signals, Risto Ilmoniemi and Jukka Sarvas present the basic physical and mathematical principles of magnetoencephalography (MEG) and electroencephalography (EEG), describing what kind of information is available in the neuroelectromagnetic field and how the measured MEG and EEG signals can be analyzed. Unlike most previous works on these topics, which have been collections of writings by different authors using different conventions, this book presents the material in a unified manner, providing the reader with a thorough understanding of basic principles and a firm basis for analyzing data generated by MEG and EEG. The book first provides a brief introduction to brain states and the early history of EEG and MEG, describes the generation of electromagnetic fields by neuronal activity, and discusses the electromagnetic forward problem. The authors then turn to EEG and MEG analysis, offering a review of linear and matrix algebra and basic statistics needed for analysis of the data, and presenting several analysis methods: dipole fitting; the minimum norm estimate (MNE); beamforming; the multiple signal classification algorithm (MUSIC), including RAP-MUSIC with the RAP dilemma and TRAP-MUSIC, which removes the RAP dilemma; independent component analysis (ICA); and blind source separation (BSS) with joint diagonalization.

College Aspirations and Access in Working Class Rural Communities: The Mixed Signals, Challenges, and New Language First-Generation Students Encounter explores how a working class, rural environment influences rural students’ opportunities to pursue higher education and engage in the college choice process. Based on a case study with accounts from rural high school students and counselors, this book examines how these communities perceive higher education and what challenges arise for both rural students and counselors. The book addresses how college knowledge and university jargon illustrate the gap between rural cultural capital and higher education cultural capital. Insights about approaches to reduce barriers created by college knowledge and university jargon are shared and strategies for offering rural students pathways to learn academic language and navigate higher education are presented for both secondary and higher education institutions.
