Tens of millions of people around the world live with chronic pain - many in such severe pain they are disabled by it. The Institute of Medicine estimates that chronic pain costs the U.S. alone $560 to $635 billion a year in direct medical costs and lost productivity. Morphine, an effective painkiller, costs only three cents a dose, yet because of excessive regulation in many countries, it is unavailable to millions of people who need it, even at the end of life. The World Health Organization notes that in addition to the one million end-stage AIDS/HIV patients who can't get morphine and...

Since the beginning of recorded history, Iran/Persia has been one of the most important world civilizations. Iran remains a distinct civilization today despite its status as a major Islamic state with broad regional influence and its deep integration into the global economy through its vast energy reserves. Yet the close attention paid to Iran in recent decades stems from the impact of the 1979 revolution, which unleashed ideological shock waves throughout the Middle East that reverberate to this day. Many observers look at Iran through the prism of the Islamic Republic's adversarial...

What is the principle purpose of a brain? A simple question, but the answer has taken millennia for us to begin to understand. So critical for our everyday existence, the brain still remains somewhat of a mystery. Gary L. Wenk takes us on a tour of what we do know about this enigmatic organ, showing us how the workings of the human brain produce our thoughts, feelings, and fears, and answering questions such as: How did humans evolve such a big brain? What is an emotion and why do we have them? What is a memory and why do we forget so easily? How does your diet affect how you think and feel?...

The Zika Virus transitioned from a rare and relatively mild tropical illness to a full-blown global health crisis in the span of approximately one year. Now active in more than 60 countries, Zika is an epidemic unlike any in history: a virus spread by both mosquitos and sex, and one whose most significant effect -- congenital birth defects -- might not be revealed until months after infection.
Zika: What Everyone Needs to Know(R) offers both a summary of the virus' history to date and an expert overview of what's known -- and unknown -- about its medical impacts. Written in clear...

Acquired by the United States from Spain in 1898, Puerto Rico has a peculiar status among Latin American and Caribbean countries. As a Commonwealth, the island enjoys limited autonomy over local matters, but the U.S. has dominated it militarily, politically, and economically for much of its recent history. Though they are U.S. citizens, Puerto Ricans do not have their own voting representatives in Congress and cannot vote in presidential elections (although they are able to participate in the primaries). The island's status is a topic of perennial debate, both within and beyond its shores. In...

Although climate change and pollution make near-daily appearances in the news, humans have not always recognized that the environment needs to be protected. Only after the publication of Rachel Carson's Silent Spring in 1962 did environmental protection became a political and social priority.

In Environmental Protection: What Everyone Needs to Know(R), environmental lawyer Pamela Hill offers clear, engaging answers to some of the most pressing questions facing us today. She discusses the science behind current environmental issues, defining key terms such as ecosystems,...

3000. That's the number of marketing messages the average American confronts on a daily basis from TV commercials, magazine and newspaper print ads, radio commercials, pop-up ads on gaming apps, pre-roll ads on YouTube videos, and native advertising on mobile news apps. These commercial messages are so pervasive that we cannot help but be affected by perpetual come-ons to keeping buying. Over the last decade, advertising has become more devious, more digital, and more deceptive, with an increasing number of ads designed to appear to the untrained eye to be editorial content. It's easy to see...

Around 1900, physicists started to discover particles like electrons, protons, and neutrons, and with these discoveries believed they could predict the internal behavior of the atom. However, once their predictions were compared to the results of experiments in the real world, it became clear that the principles of classical physics and mechanics were far from capable of explaining phenomena on the atomic scale. With this realization came the advent of quantum physics, one of the most important intellectual movements in human history. Today, quantum physics is everywhere: it explains how our...

We live more and more of our lives online; we rely on the internet as we work, correspond with friends and loved ones, and go through a multitude of mundane activities like paying bills, streaming videos, reading the news, and listening to music. Without thinking twice, we operate with the understanding that the data that traces these activities will not be abused now or in the future. There is an abstract idea of privacy that we invoke, and, concrete rules about our privacy that we can point to if we are pressed. Nonetheless, too often we are uneasily reminded that our privacy is not...

As the largest and youngest minority group in the United States, the 60 million Latinos living in the U.S. represent the second-largest concentration of Hispanic people in the entire world, after Mexico. Needless to say, the population of Latinos in the U.S. is causing a shift, not only changing the demographic landscape of the country, but also impacting national culture, politics, and spoken language. While Latinos comprise a diverse minority group -- with various religious beliefs, political ideologies, and social values-commentators on both sides of the political divide have lumped Latino...
