In 'Everything Is Tuberculosis,' John Green turns his attention to a deadly disease

Guns, Germs, and Steel is Jared Diamond’s attempt to determine why societies historically took different paths. It was named one of TIME’s best non-fiction books of all time, awarded the Pulitzer Prize, and turned into a PBS documentary.

Diamond argues that differences between societies were caused by environmental factors that affected the historical development of those societies, not biological differences between the people of the societies. These factors led Eurasians (people from Asia, Europe, and North Africa) to historically have strategic advantages over non-Eurasians, including advanced knowledge, centralized governments, and immunity to infectious diseases.

With these advantages, Eurasian colonists came to dominate much of the world. Diamond believes Eurasians had these advantages primarily because their native geography supported bountiful food production, which allowed for the development of other advantages in technology, knowledge, and government. In our guide, we’ll see how Diamond draws the link between food production and these advantages, we’ll fact-check his ideas, and we’ll consider how Diamond’s view has been received by other experts.

Measles, tuberculosis, and polio—once controlled by vaccines—are spreading again in the US. We’ll look at why such dormant diseases are making a comeback, their deadly history, and the new dangers they pose.

Have you ever wondered why our homes are built the way they are? In At Home, Bill Bryson explores how the average home—the materials from which they’re built, their layouts, and the tools and technologies within them—reveals how people lived their daily lives throughout history. By tracing how homes have evolved to meet people’s changing needs, we can better understand not just what life was once like, but also why modern homes look and function the way they do.

In this guide, we’ll look at why humans started building homes, what materials they built them from, and when homes started to become a place of comfort. Then, we’ll examine how families stored and prepared food, dealt with health and safety challenges, and other aspects of home life. We’ll supplement Bryson’s discussions by exploring how homes evolved in cultures around the world, and discuss how new technology continues to transform our homes.

Paul Farmer has worked for decades to provide health care to patients in Haiti and around the world. A doctor and anthropologist by training, Farmer saw the health of a nation’s people as a product of its culture and political history. For Haiti, centuries of political strife—often at the hands of imperialist powers—had left it one of the most impoverished countries in the western hemisphere.

Despite prevailing wisdom that it was too costly to treat patients in poor countries for diseases like drug-resistant tuberculosis and AIDS, Farmer strived to treat everyone who needed care. His multi-pronged approach included prioritizing preventive services, changing international healthcare policy, and lowering the cost of important drugs. His organization’s approach is considered a model for providing treatment to patients in poor countries.

For millennia, humans struggled with three serious problems—famine, plagues, and war—which led to the deaths of millions of people and to the rise and fall of global empires. People coped with these problems and answered life's questions with religion. However, in the modern era, we no longer rely on prayer—we’ve mostly overcome these three problems through the development of technology and medical knowledge.

In Homo Deus, Yuval Noah Harari, a professor at the Hebrew University in Jerusalem, envisions a future in which technology replaces humanist ideals and liberal government. Dissecting the concepts of religion, immortality, and technology, Harari argues that the world of the future may be run by advanced algorithms and artificial intelligence, not human beings.

Millions of people throughout the world live on less than 99 cents a day. MIT professors Esther Duflo and Abhijit Banerjee won the Nobel Prize in Economic Sciences for their efforts to study the causes of such poverty—Poor Economics demonstrates their unique approach.

They analyze poverty by asking small, pointed questions about specific aspects of the lives of the poor. Their goal is to develop a detailed picture of how the poor live and how policy interventions affect their lives so that policymakers can better design interventions that help them. Since publishing Poor Economics in 2011, their approach has come to dominate the field.

In our guide, we’ll see what the authors discover when they closely examine the lives of the world’s poorest people. Along the way, we’ll note critiques of their approach and share relevant updates on the current status of global poverty.

In The White Man’s Burden, economist, NYU professor, and Brookings Institution senior fellow William Easterly argues that the global humanitarian aid system is fundamentally flawed. His main critique is that the international aid system prioritizes top-down, centralized, and tightly directed aid distribution—all controlled by people in rich countries (primarily the United States and those in Western Europe), far away from the developing world that they're meant to be serving. Because the aid community is so disconnected, it creates big plans and sweeping missions that are overly ambitious and completely unsuited for the reality on the ground, it overlooks local needs and concerns, and it rarely holds itself accountable for its failures.

In this guide, we’ve updated some of Easterly’s statistics, supplemented his ideas with more recent examples, and incorporated alternative and opposing viewpoints from leading experts in the fields of economics, political theory, and business.
