What We’re Following

Trump at the UN: In his first speech before the United Nations General Assembly, President Trump declared the U.S. ready and willing to “totally destroy North Korea” in defense of itself or its allies—a dangerous assertion, since the effects of using force in North Korea would be serious and tragic. He also implied that he may withdraw from the nuclear deal with Iran that the U.S. entered under President Obama. Overall, writes Peter Beinart, the speech was a direct rebuke of Obama’s previous emphasis on international cooperation, and an advancement of Trump’s own inconsistent ideas of sovereignty.

Mueller and Manafort: New reports on the federal investigation into Paul Manafort say that Trump’s former campaign chairman was under surveillance by the FBI before and after last year’s presidential election, and that Manafort was informed in July he would soon be indicted in Special Counsel Robert Mueller’s Russia investigation. The emerging details raise several questions about the probe and its findings so far, but they don’t vindicate Trump’s claims that he himself was wiretapped by the Obama administration. Rather, they likely spell continued legal trouble for Trump’s team—which is now using Republican National Committee funds to pay his legal fees.

The Right Takes Sides: Senators John McCain of Arizona and Lisa Murkowski of Alaska are under pressure to make a decision on the latest effort to repeal Obamacare after their “no” votes killed the effort in July—and their states’ governors are taking opposing positions. Meanwhile, conservative publications are struggling to respond to the rising populist sentiment among their readers, and the Republican party is grappling with how it may have laid the groundwork for Trump’s current breaches of political norms.

Evening Read

Sarah Zhang on tracing a rare disorder through French Canadian genealogy records:

Whenever a small group of people leave a large population (France) to found a new one (New France), they bring with them a particular set of mutations. Some of these mutations will by chance be more common in the new population and others less so. As a result, some rare genetic disorders disproportionately impact French Canadians.

One of these is Leber’s hereditary optic neuropathy, which causes vision loss, usually in young men. Recently, geneticists using French Canadian genealogy have reexamined the effects of Leber’s and found a striking pattern of inheritance: It seems to show a long-theorized but never-seen-in-humans pattern called the “mother’s curse.”

Keep reading here, as Sarah explains how the rare disorder hides from natural selection—and how scientists traced its presence in Canada back to a single woman’s DNA.


What Do You Know … About Business?

This week, we take a look back: Inventions as simple as air-conditioning have had a lot to do with shaping city skylines, jump-starting economies, and even, some say, picking presidents. Historic inequities creep into how Americans climb out of poverty, and even how they network. And Black Monday, the 1987 crash when Wall Street saw its steepest falls ever, presaged the 2008 financial crisis—but regulators still haven’t learned its lessons.

Urban Developments

Our partner site CityLab explores the cities of the future and investigates the biggest ideas and issues facing city dwellers around the world. Adam Sneed shares three of today’s top stories:

Fans of the Insane Clown Posse made news by rallying on the National Mall this weekend, but make no mistake: It wasn’t a joke. The Juggalos have something important to say.

The Northeast and Midwest are dotted with small, inner-ring suburbs that are struggling. What’s to be done? Consider merging them with the larger cities next door.

The federal government spends $7.6 billion each year paying (mostly affluent) Americans to drive to work. It's worsening traffic, pollution, and quality of life—and it’s time to stop.

Reader Response

In a recent edition of our magazine feature "The Big Question," we asked some folks to nominate the most underappreciated medical inventions in history. David L. Lerner, a doctor and reader, adds:

It is especially ironic that Dr. Jack Ende’s reason for nominating the stethoscope as the most underappreciated medical invention is that it “connects doctors to patients” and counters the erosion of the doctor-patient relationship. Dr. René Laënnec invented the device in 1816 specifically to distance himself from patients, against whose breasts he would otherwise have been expected to press his ear. Over the past two centuries, progressively longer tubing has been incorporated into stethoscopes, resulting in even greater distancing, both literal and metaphorical.
