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.

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.

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?”

When Bill and Melinda Gates announced on Monday that they would be ending their 27-year marriage, they tweeted in tandem that they “no longer believe [they] can grow together as a couple.” The reasoning wasn’t unusual for a 21st-century divorce, but their private emotional journey has highly atypical financial implications: Between their personal holdings and the charitable foundation they started together, the amount of money they control—somewhere around $180 billion—is roughly equal to the annual GDP of Kazakhstan or Qatar.

The Bill and Melinda Gates Foundation, which they launched 25 years after Bill co-founded Microsoft, is one of the biggest private charitable foundations in the world, with an endowment of about $50 billion. In a sense, the jobs of its 1,600 employees and its investments in malaria prevention and early-childhood education have rested on the bedrock of Bill and Melinda’s marriage.

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.
