Every week for the eighth and final season of Game of Thrones, three Atlantic staffers have been discussing new episodes of the HBO drama. Because no screeners were made available to critics in advance this year, we’ll be posting our thoughts on the series finale in installments.

The bet was on, and it was over the fate of humanity. On one side was the Stanford biologist Paul R. Ehrlich. In his 1968 best seller, The Population Bomb, Ehrlich insisted that it was too late to prevent a doomsday apocalypse resulting from overpopulation. Resource shortages would cause hundreds of millions of starvation deaths within a decade. It was cold, hard math: The human population was growing exponentially; the food supply was not. Ehrlich was an accomplished butterfly specialist. He knew that nature did not regulate animal populations delicately. Populations exploded, blowing past the available resources, and then crashed.

In his book, Ehrlich played out hypothetical scenarios that represented “the kinds of disasters that will occur.” In the worst-case scenario, famine rages across the planet. Russia, China, and the United States are dragged into nuclear war, and the resulting environmental degradation soon extinguishes the human race. In the “cheerful” scenario, population controls begin. Famine spreads, and countries teeter, but the major death wave ends in the mid-1980s. Only half a billion or so people die of starvation. “I challenge you to create one more optimistic,” Ehrlich wrote, adding that he would not count scenarios involving benevolent aliens bearing care packages.

In 1996, a group of European researchers found that a certain gene, called SLC6A4, might influence a person’s risk of depression.

It was a blockbuster discovery at the time. The team found that a less active version of the gene was more common among 454 people who had mood disorders than in 570 who did not. In theory, anyone who had this particular gene variant could be at higher risk for depression, and that finding, they said, might help in diagnosing such disorders, assessing suicidal behavior, or even predicting a person’s response to antidepressants.

Back then, tools for sequencing DNA weren’t as cheap or powerful as they are today. When researchers wanted to work out which genes might affect a disease or trait, they made educated guesses, and picked likely “candidate genes.” For depression, SLC6A4 seemed like a great candidate: It’s responsible for getting a chemical called serotonin into brain cells, and serotonin had already been linked to mood and depression. Over two decades, this one gene inspired at least 450 research papers.

To feel relief at my mother’s being dead was once unthinkable, but then the news came from Ireland. It would have crushed her. An immigrant’s daughter, my mother lived with an eye cast back to the old country, the land against which she measured every virtue. Ireland was heaven to her, and the Catholic Church was heaven’s choir. Then came the Ryan Report.

Not long before The Boston Globe began publishing its series on predator priests, in 2002—the “Spotlight” series that became a movie of the same name—the government of Ireland established a commission, ultimately chaired by Judge Sean Ryan, to investigate accounts and rumors of child abuse in Ireland’s residential institutions for children, nearly all of which were run by the Catholic Church.

President Donald Trump declared a national emergency and banned equipment made by tech firms of “foreign adversaries” from operating in the U.S. The Department of Commerce followed up, listing Huawei and dozens of other Chinese firms as risks to American national security, prohibiting them from selling or buying in the U.S. market. The actions were much broader and more bare-knuckled than even China hawks had expected.

Trump’s supporters are test marketing the argument that only he could or would get tough on China. Steve Cortes, writing in RealClearPolitics, compared Trump on China to Ronald Reagan on the Soviet Union—ahead of his time in confronting its malevolence. Greg Autry wrote in Foreign Policy “Trump’s China Policy Is a Triumph.” The Wall Street Journal reported that CEOs have been coming around to support tariffs as “American business’s best shot at addressing those long-standing grievances.” Even The New York Times acknowledged that Trump has overturned years of failed multilateral efforts to deal with China.

In my long career as an academic jack-of-all-trades, I sometimes teach law students Jurisprudence—that is, Philosophy of Law. The course begins with the question “What is law?” and its corollary, “What is lawlessness?”

The latter comes in two flavors. The first is anarchy—Hobbes’s “war of all against all,” a Mad Max moonscape in which only stealth and brute force provide even a semblance of safety. Such situations existed for millennia and, though relatively rare, exist in remote parts of the globe today.

But there is an authoritarian lawlessness that is far more common in the 21st century, and next time I teach the course, I will have the most precise example of this second version I have ever seen: the dispute over 26 U.S. Code § 6103(f)(1), which reads: “Upon written request from the chairman of the Committee on Ways and Means of the House of Representatives, the chairman of the Committee on Finance of the Senate, or the chairman of the Joint Committee on Taxation, the Secretary [of the Treasury] shall furnish such committee with any return or return information specified in such request,” subject only to a requirement that the return be considered in closed session.

At first glance, the hagfish—a sinuous, tubular animal with pink-grey skin and a paddle-shaped tail—looks very much like an eel. Naturalists can tell the two apart because hagfish, unlike other fish, lack backbones (and, also, jaws). For everyone else, there’s an even easier method. “Look at the hand holding the fish,” the marine biologist Andrew Thaler once noted. “Is it completely covered in slime? Then, it’s a hagfish.”

Hagfish produce slime the way humans produce opinions—readily, swiftly, defensively, and prodigiously. They slime when attacked or simply when stressed. On July 14, 2017, a truck full of hagfish overturned on an Oregon highway. The animals were destined for South Korea, where they are eaten as a delicacy, but instead, they were strewn across a stretch of Highway 101, covering the road (and at least one unfortunate car) in slime.

To the six women currently running in the 2020 presidential race, I offer this advice: Study German Chancellor Angela Merkel, the world’s most successful living politician, on the basis of both achievement and longevity. Now in her 14th year as chancellor of Europe’s powerhouse, Merkel has upended the rules of the male-dominated German political culture, and transformed her country along the way.

Without fanfare, Merkel made German society friendlier to the ambitions of women. Merkel’s handpicked successor to lead the Christian Democratic Union is a woman, there are six other women in her cabinet, and women abound in her circle of advisers. Alexander Gauland, the leader of Germany’s far-right political party AfD, recently asked, “Are there no men left in the CDU?” The party still has quite a few men; they just don’t run it any longer.

Commencement speakers have a routine: a few words of encouragement, a good—or maybe not so good—joke, and a bit of advice. But this year, Robert F. Smith, the billionaire founder of the private equity firm Vista Equity Partners, who delivered the commencement address on Sunday morning at Morehouse College, a historically black college in Atlanta, took a different approach.

“You great Morehouse men are bound only by the limits of your own conviction and creativity,” Smith told the soon-to-be graduates of the venerated HBCU (historically black college or university). Smith then did something astonishing: He did what he could to make that actually true, telling the class that his family would be eliminating the graduates’ student debt. The crowd, as expected, went wild.

The final image of Knock Down the House, the hit documentary about a quartet of 2018 congressional primary candidates, shows Alexandria Ocasio-Cortez and her boyfriend newly arrived at the east plaza of the Capitol building in Washington, D.C. She has just been elected to Congress, but not yet taken office. They both start to cry; the waterworks run at a low gurgle throughout the movie, and at this point the viewer won’t be alarmed by another eruption.

Suddenly scooters appear, and the couple, with infectious delight, takes off in zigzags across the plaza, which is usually closed to tourists. The image thus combines three elements—Millennials, scooters, and trespassing—that seem designed to make a certain kind of conservative Republican’s head explode. The poor fellow will probably view the film as an exercise in trolling, a giddy, unapologetic version of his worst nightmare.
