The little Havanese likes to sit in a window of the one-story house, looking out onto the quiet street in Boca Chica, Texas. From its perch, it can watch neighbors passing by, glossy black grackles pecking in the grass, and palm trees swaying in the breeze. The dog’s presence is usually a sign that its owner, Elon Musk, is in town. That, and the Tesla parked in the driveway.

There are other, more conspicuous signs that Musk has gotten comfortable in this remote part of South Texas, near the U.S.-Mexico border. The hulking manufacturing tents just down the road. The steel strewn on the ground. The mechanical hum of machinery as workers in hard hats assemble spaceship after spaceship.

Musk has built a shipyard here. This is the staging area for SpaceX’s founding dream, the reason Musk got into the rocket business: to put human beings on Mars, not to drop a flag and go home, but to stay and survive. That Mars might be a terrible place to live is irrelevant. Musk believes that humankind should exist on more than one planet, and that we should start soon.

Liz Cheney, the representative of Wyoming, the daughter of a former vice president, and a lifelong conservative Republican, is facing a purge.

Cheney’s transgression? She has continued to insist, truthfully, that former President Donald Trump’s claims about the 2020 election are false, after having voted to impeach him in March for inciting a mob that stormed the Capitol in an attempt to overturn the result.

Yesterday, Steve Scalise, the No. 2 Republican in the House, publicly advocated for removing Cheney from her leadership post as the third-ranking House Republican, and replacing her with Elise Stefanik, who has obsequiously amplified Trump’s lies about voter fraud. “This is about whether the Republican Party is going to perpetuate lies about the 2020 election and attempt to whitewash what happened on January 6,” Cheney’s spokesperson, Jeremy Adler, told The New York Times. “Liz will not do that. That is the issue.”

“How to Build a Life” is a weekly column by Arthur Brooks, tackling questions of meaning and happiness.

“You are … irritating and unbearable, and I consider it most difficult to live with you.” So wrote Johanna Schopenhauer in a 1807 letter to her 19-year-old son Arthur. “No one can tolerate being reproved by you, who also still show so many weaknesses yourself, least of all in your adverse manner, which in oracular tones, proclaims this is so and so, without ever supposing an objection. If you were less like you, you would only be ridiculous, but thus as you are, you are highly annoying.”

Lurking among the jubilant Americans venturing back out to bars and planning their summer-wedding travel is a different group: liberals who aren’t quite ready to let go of pandemic restrictions. For this subset, diligence against COVID-19 remains an expression of political identity—even when that means overestimating the disease’s risks or setting limits far more strict than what public-health guidelines permit. In surveys, Democrats express more worry about the pandemic than Republicans do. People who describe themselves as “very liberal” are distinctly anxious. This spring, after the vaccine rollout had started, a third of very liberal people were “very concerned” about becoming seriously ill from COVID-19, compared with a quarter of both liberals and moderates, according to a study conducted by the University of North Carolina political scientist Marc Hetherington. And 43 percent of very liberal respondents believed that getting the coronavirus would have a “very bad” effect on their life, compared with a third of liberals and moderates.

Lidia Morawska has been working in her office for months. You might think that’s because she’s an aerosols expert, and her work is crucial for helping bring the pandemic to heel. But really, it’s because she’s an aerosols expert at Queensland University of Technology, in Australia. The country has recorded only three cases of community transmission of the coronavirus in the past week. Although Australian offices and classrooms have lowered their maximum capacities and are still observing social-distancing guidelines, Morawska told me, no one wears a mask to work, except in the rare case of a local outbreak. “Basically, life is back to normal,” she said.

Still, going back to work took some adjustment at first. “It felt strange,” Morawska said. “It was that feeling [of being] in between. What’s real? What’s not?”

Several days ago, the mega-popular podcast host Joe Rogan advised his young listeners to skip the COVID-19 vaccine. “I think you should get vaccinated if you’re vulnerable,” Rogan said. “But if you’re 21 years old, and you say to me, ‘Should I get vaccinated?’ I’ll go, ‘No.’”

Rogan’s comments drew widespread condemnation. But his view is surprisingly common. One in four Americans says they don’t plan to take the COVID-19 vaccine, and about half of Republicans under 50 say they won’t get a vaccine. This partisan vaccine gap is already playing out in the real world. The average number of daily shots has declined 20 percent in the past two weeks, largely because states with larger Trump vote shares are falling off the pace.

A real scientific advance, like a successful date, needs both preparation and serendipity. As a tired, single medical student, I used to feel lucky when I managed two good dates in a row. But career scientists must continually create this kind of magic. Universities judge their research faculty not so much by the quality of their discoveries as by the number of papers they’ve placed in scholarly journals, and how prestigious those journals happen to be. Scientists joke (and complain) that this relentless pressure to pad their résumés often leads to flawed or unoriginal publications. So when Randall Munroe, the creator of the long-running webcomic XKCD, laid out this problem in a perfect cartoon last week, it captured the attention of scientists—and inspired many to create versions specific to their own disciplines. Together, these became a global, interdisciplinary conversation about the nature of modern research practices.

On a Friday afternoon in early March, I felt an urge I hadn’t experienced in more than a year: I wanted to buy new clothes. Outside clothes. Clothes in which I would be perceived, by others. Clothes to wear to a party. The late-winter sun had started to warm things up a bit, I was a week and a half removed from my first Pfizer shot, and those two facts combined to cause a flare of optimism so intense that I needed to express it in what has historically been my preferred manner of celebration: by buying some stuff on the internet.

The first order of business was remembering where I had bought my outside clothes before everything went to hell—ASOS? Madewell? Nordstrom? As I dug through my brain, past all the recipes and the opinions about lesser Netflix shows that I had accumulated in the past year, I opened browser tabs. I was ready to be sold on the possibilities of the year ahead, and I wanted them to include sweaty crowds and recreational drugs and other people’s hands. I wanted to take as many steps as I possibly could toward the person I might be by July.

When the cicadas of Brood X start to swarm the United States in their billions, try to look beyond their overwhelming numbers. Instead, focus on just one of them. Despite appearances, that individual cicada will be a swarm unto itself—the insect and a community of organisms living inside it. Their lives have been so tightly entwined that they cannot survive alone. Their fates have been so precariously interlinked that their future is uncertain. And their relationship is so unusual that when John McCutcheon first stumbled upon it in 2008, he had no idea what he had found. Sitting in a basement laboratory and staring at the data, his reaction was less Eureka! he told me, and more How did I mess this up?

Some of the changes are obvious: Compared with the economic strategies of former Presidents Bill Clinton and Barack Obama, Joe Biden is proposing more new spending and more new taxes than either of his Democratic predecessors, and he’s abandoned their support for negotiating new free-trade agreements.

But Biden is also diverging from his predecessors’ approaches in ways that have drawn much less attention—yet may prove even more consequential. Particularly on racial-, gender-, and class-inequality issues, Biden’s separation from those past presidents reflects both an evolution in thinking among Democratic-leaning economists and a bet that boldness may be a better political strategy than moderation.
