On Wednesday, two representatives of the United States government held press briefings, both of them touching on one of the most astonishing news stories of the Trump presidency—a series of events that had begun two days earlier, when Trump traveled to Helsinki to meet, behind closed doors, with Vladimir Putin.

Here was the White House press secretary Sarah Huckabee Sanders, responding to a question from The New York Times’s Maggie Haberman about the notion Putin raised of a group of U.S. officials, including the former ambassador to Russia, Mike McFaul, being interrogated by Russia: “The president is going to meet with his team, and we’ll let you know when we have an announcement on that.”

Here, on the other hand, was Heather Nauert, the State Department spokesperson, on the same issue: “The overall assertions are absolutely absurd—the fact that they want to question 11 American citizens and the assertions that the Russian Government is making about those American citizens. We do not stand by those assertions.”

On Wednesday morning, in the midst of yet another contentious news cycle dominated by coverage of Russian election meddling, I tweeted a kind of thought experiment: “If Trump & co. just pivoted to ‘Aren’t you glad Russia helped us defeat Hillary Clinton?’ would there be any serious blowback from his base?”

The question was rhetorical. The answers that began trickling in were not.

“No,” said Cassandra Fairbanks, a writer at the right-wing news and conspiracy website Gateway Pundit (and a former Sputnik employee). “I mean, I would be cool with it. I’m already there. If Russia was involved we should thank them.”

“No,” responded another self-identified Trump voter. “Hillary is a greater threat to our Republic.”

In recent years, Alzheimer’s disease has occasionally been referred to as “type 3” diabetes, though that moniker doesn’t make much sense. After all, though they share a problem with insulin, type 1 diabetes is an autoimmune disease, and type 2 diabetes is a chronic disease caused by diet. Instead of another type of diabetes, it’s increasingly looking like Alzheimer’s is another potential side effect of a sugary, Western-style diet.

In some cases, the path from sugar to Alzheimer’s leads through type 2 diabetes, but as a new study and others show, that’s not always the case.

A longitudinal study, published Thursday in the journal Diabetologia, followed 5,189 people over 10 years and found that people with high blood sugar had a faster rate of cognitive decline than those with normal blood sugar—whether or not their blood-sugar level technically made them diabetic. In other words, the higher the blood sugar, the faster the cognitive decline.

When did America become untethered from reality?

I first noticed our national lurch toward fantasy in 2004, after President George W. Bush’s political mastermind, Karl Rove, came up with the remarkable phrase reality-based community. People in “the reality-based community,” he told a reporter, “believe that solutions emerge from your judicious study of discernible reality … That’s not the way the world really works anymore.” A year later, The Colbert Report went on the air. In the first few minutes of the first episode, Stephen Colbert, playing his right-wing-populist commentator character, performed a feature called “The Word.” His first selection: truthiness. “Now, I’m sure some of the ‘word police,’ the ‘wordinistas’ over at Webster’s, are gonna say, ‘Hey, that’s not a word!’ Well, anybody who knows me knows that I’m no fan of dictionaries or reference books.

As a candidate, Donald Trump promised to run the U.S. government in the same way he ran his businesses. At his Helsinki meeting with Russian president Vladimir Putin, President Donald Trump honored that commitment.

According to the Russian government, Trump pledged the United States to a series of agreements on matters ranging from nuclear forces to Syria. The U.S. government seems to have no idea what those agreements might be—or whether they exist at all. It’s unclear whether even Trump himself knows what he promised or did not promise. Trump’s post-meeting tweets reference “implementing” things “discussed”—which implies some kind of agreement, but does not actually use the word.

The last episode of Trump’s personal diplomacy provides a disquieting precedent. Trump emerged from his meeting with North Korean dictator Kim Jong Un convinced he had gained dramatic new concessions. He tweeted triumphantly on June 13: “Just landed - a long trip, but everybody can now feel much safer than the day I took office. There is no longer a Nuclear Threat from North Korea. Meeting with Kim Jong Un was an interesting and very positive experience. North Korea has great potential for the future!”

Carol Dweck, a psychology professor at Stanford University, remembers asking an undergraduate seminar recently, “How many of you are waiting to find your passion?”

“Almost all of them raised their hand and got dreamy looks in their eyes,” she told me. They talked about it “like a tidal wave would sweep over them.” Sploosh. Huzzah! It’s accounting!

Would they have unlimited motivation for their passion? They nodded solemnly.

“I hate to burst your balloon,” she said, “but it doesn’t usually happen that way.”

What Dweck asked her students is a common refrain in American society. The term “Follow your passion” has increased ninefold in English books since 1990. “Find something you love to do and you’ll never have to work a day in your life” is another college-counseling standby of unknown provenance.

In 1945, George Orwell distinguished between “nationalism” and “patriotism.” Nationalism, he argued, is the belief that your nation should dominate others. It “is inseparable from the desire for power.” A nationalist, Orwell argued, “thinks solely, or mainly, in terms of competitive prestige … his thoughts always turn on victories, defeats, triumphs and humiliations.” Patriotism, by contrast, involves “devotion to a particular place and a particular way of life, which one … has no wish to force on other people.” Orwell’s explanation of patriotism is brief. But his implication is that while nationalism is about the relationship between your country and other countries, patriotism is about the relationship between your country and yourself. It derives from the Latin “pater,” meaning father. Just as devotion to family requires placing its well being above your own, devotion to country—patriotism—extends that principle to the nation as a whole.

As a young child I missed a question on a psychological test: “What comes in a bottle?”

The answer was supposed to be milk. I said beer.

Milk almost always came in cartons and plastic jugs, so I was right. But this isn’t about rehashing old grudges. I barely even think about it anymore! The point is that the test was a relic of a time before me, when milk did come in bottles. It arrived on doorsteps each morning, by the hand of some vanishing man. And just as such a world was alien to me as a kid, the current generation of small children might miss a similar question: “Where does milk come from?”

Many would likely answer almonds or beans or oats.

Indeed, the already booming nut-milk industry is projected to grow another 50 percent by 2020. Much of this is driven by beliefs about health, with ads claiming “dairy free” as a virtue that resonates for nebulous reasons—many stemming from an earlier scare over saturated fat—among consumers lactose intolerant and tolerant alike. The dairy industry is now scrambling to market milk to Millennial families, as the quintessential American-heartland beverage once thought of as necessary for all aspiring, straight-boned children has become widely seen as something to be avoided.

For people with bipolar disorder, manic episodes can be euphoric, but they can also be terrifying. In the throes of mania, some people feel like they are superhuman. They start new projects and stay up all night to work on them. In the worst cases, they cease thinking coherently: They might attempt to walk into the sea or fly off the roof.

Though medications can help manage the symptoms, no pill is perfect, and all of them have side effects. Bipolar disorder appears to be at least partly genetic, but environmental factors also play a role, perhaps by switching different genes on and off, which might spark manic episodes. And the thing that might be switching on some of these genes, according to a new study, is rather surprising: a category of preservatives in beef jerky called nitrates.

H. R. McMaster, Donald Trump’s former national-security adviser, used to warn of the dangers of “revisionist powers.” He had in mind countries like China and Russia that are newly ascendant and determined to amend to their advantage the global status quo: a decades-old, U.S.-led international system of free trade, military and diplomatic alliances, and liberal rules and institutions that govern how countries conduct themselves.

But the U.S. president’s recent Europe trip, which whisked him from a confrontational breakfast with the secretary general of NATO to a conciliatory lunch with the president of Russia, made one thing clearer than it’s ever been before: The call is also coming from inside the house. Trump is a revisionist, even if many of his advisers may still conceive of the United States as the world’s leading status-quo power.
