While popularized by President Donald Trump, the term "fake news" actually originated toward the end of the 19th century, in an era of rampant yellow journalism. Since then, it has come to encompass a broad universe of news stories and marketing strategies ranging from outright lies, propaganda, and conspiracy theories to hoaxes, opinion pieces, and satire―all facilitated and manipulated by social media platforms. This title explores journalistic and fact-checking standards, Constitutional protections, and real-world case studies, helping readers identify the mechanics, perpetrators, motives, and psychology of fake news. A final chapter explores methods for assessing and avoiding the spread of fake news.

What do giant squids, mantis shrimp, and fireflies have in common? These animals, along with a wide range of creatures, are able to give off light; this is called bioluminescence. Different species use different chemistries to bioluminesce, and they produce their light for a variety of reasons, including communication, hunting, and self-defense. Bioluminescence is a unique and fascinating adaptation found in the animal kingdom. Surprisingly, about half of all known phyla (a classification for animals that share the same body type) contain some bioluminescent species. Scientists don't yet understand all facets of bioluminescence, but they have managed to harness the glow and use it in a myriad of ways. One of the most important applications involves using bioluminescence as a microscope in medical studies. For example, laboratory scientists can create fluorescent malaria parasites to track the path by which the disease is spread from a mosquito to the animal it bites. Bioluminescent proteins are also helping researchers learn more about cancer, HIV and other viruses, and complex neurological processes. In fact, bioluminescent proteins are so useful to twenty-first-century medicine that two groups of scientists, one in 2008 and the other in 2014, were awarded the Nobel Prize in Chemistry for their work with these proteins and related technologies. Even artists and fashion designers use bioluminescence in their work to create glowing, light-sensitive paintings and clothing lines. Author Marc Zimmer, a world-renowned specialist in fluorescent proteins, takes readers on a glowing journey into the frontiers of bioluminescence.

Twenty-first-century minimalism is an increasingly mainstream response to global environmental crises such as climate change, the garbage glut, fast fashion, and other manifestations of the harmful impact of consumerism. Originally founded in the art world in the decades after World War II, minimalism has evolved into an Earth-friendly lifestyle focusing on the three Rs (reducing, recycling, and reusing) and on simplifying individual needs to reduce one's carbon imprint, manage anxiety and depression, and prioritize human interaction over the impulse to acquire for the sake of acquisition. Hands-on activities, how-to tips, and profiles of practicing minimalists offer real-world examples for incorporating minimalism into your life.

Experiment: A child is deliberately infected with the deadly smallpox disease without his parents' informed consent. Result: The world's first vaccine. Experiment: A slave woman is forced to undergo more than thirty operations without anesthesia. Result: The beginnings of modern gynecology. Incidents like these paved the way for crucial, lifesaving medical discoveries. But they also harmed and humiliated their test subjects. How do doctors balance the need to test new medicines and procedures with their ethical duty to protect the rights of humans? Take a journey through some of history's greatest medical advances―and its most horrifying medical atrocities―to discover how human suffering has gone hand in hand with medical advancement.

As the planet's human population explodes, so does the demand for water. About one out of every nine people in the world does not have access to safe drinking water, while one out of every five―almost 1.5 billion humans―lives in a region where water demand is outstripping supply. But as demand grows, supplies do not. Climate change has led to severe drought, flooding, and massive storms in key agricultural areas of the world. Industrial and agricultural water pollution threatens public health around the world. Environmental protection measures are not keeping up with energy-production technologies such as fracking and the corn-for-fuel market, all of which affect water usage rates and safety. Both developed and undeveloped areas of the world face challenges with water-delivery infrastructure. For example, undeveloped nations lack even the most basic water-delivery systems. Millions of global citizens are without sanitation altogether, polluting waterways with raw sewage. In the developed world, water-delivery infrastructures are aging and wasteful. Domestic and industrial overconsumption of water resources draws down supply capacity, depleting Earth's freshwater resources at an alarming rate. And, in the last few decades, private corporations have begun to take over municipal water delivery, buying the rights to freshwater supplies and selling bottled water, all for large profits. As the cost of clean water rises, many people can't afford the water they need for everyday use. Competition for clean water is increasing, and the stakes couldn't be higher. Running Dry investigates some tough questions. In a crowded world with limited water supplies, will we be able to deliver safe, clean water to an increasingly thirsty world? Can governments, businesses, and individuals work together to clean up and protect Earth's water resources? Are water conservation strategies enough to ensure a water-rich future? Or will we run dry?

Theodosia Burr, daughter of Vice President Aaron Burr, came of age in New York City when the New Nation was growing up. She attended the inauguration of President George Washington in 1789, was at her father's side on the campaign trail and at his inauguration in 1801, attended presidential addresses to Congress, and hosted the most prominent politicians and thinkers of her time.The Burrs' ideas about educating young women were revolutionary. Theodosia was an experiment in the equal treatment of women—regardless of social status—in education, family life, society, and the law. The family believed that women had an important role to play in the New Nation, and Theodosia was fully prepared.Based on research at libraries and archives, and from the rich body of letters Theodosia and her family left behind, this historical narrative introduces readers to a most unusual girl who pursued a radical new path for women.
