Over the past 50 years, scientists have made incredible progress in the application of genetic research to human health care and disease treatment. Innovative tools and techniques, including gene therapy and CRISPR-Cas9 editing, can treat inherited disorders that were previously untreatable, or prevent them from happening in the first place. You can take a DNA test to learn where your ancestors are from. Police officers can use genetic evidence to identify criminals—or innocents. And some doctors are using new medical techniques for unprecedented procedures. Genomics: A Revolution in Health and Disease Discovery delves into the history, science, and ethics behind recent breakthroughs in genetic research. Authors Whitney Stewart and Hans Andersson, MD, present fascinating case studies that show how real people have benefitted from genetic research. Though the genome remains full of mysteries, researchers and doctors are working hard to uncover its secrets and find the best ways to treat patients and cure diseases. The discoveries to come will inform how we target disease treatment, how we understand our health, and how we define our very identities.

During the Middle Ages, your position in life was based on birth. This position would follow you throughout your life. To make it easy for others to know your social class, rules about what you could wear—or not wear—were created. Such rules, called sumptuary laws, determined colors of clothing, types of fabric and trims, length of garments, types of sleeves, and types of furs. The laws also regulated shoe lengths and height, hat height, types of buttons, and even the number of buttons you could wear. People were to dress according to the class in which they were born. In this way, just by looking at someone, you could tell if they were important or not.

On April 22, 1970, an estimated twenty million people held in a teach-in to show their support for environmental protections. This new celebration, Earth Day, brought together previously fragmented issues under the same banner. It was the largest nationwide event ever, and lawmakers took notice. But one day didn't change everything. Fifty years after the first Earth Day, climate change remains a dire concern. The divide between political parties continues to widen, and environmental policy has become an increasingly partisan issue. The spread of disinformation has also made climate change a debatable idea, rather than scientific fact. A new generation of advocates continue the fight to make environmental policy a top priority for the United States and for nations around the globe
