Arnold Schwarzenegger and John McCain saw in each other a willingness to buck the Republican Party and became fast friends and political allies. Mindful of McCain’s legacy, the former California governor said on Wednesday he couldn’t stay silent in the face of President Trump’s recent spate of attacks on the late senator.  

He told me Trump’s swipes at McCain are both disgraceful and destructive. “He was just an unbelievable person,” Schwarzenegger said. “So an attack on him is absolutely unacceptable if he’s alive or dead—but even twice as unacceptable since he passed away a few months ago. It doesn’t make any sense whatsoever to do that. I just think it’s a shame that the president lets himself down to that kind of level. We will be lucky if everyone in Washington followed McCain’s example, because he represented courage.”

The camera flies high above the palm trees of Hollywood, soaring north and west, all the way to the suburb of Simi Valley, where it slows down to seek out a certain street, and then slows some more until it finds a particular house. It hovers above it, and then swoops down, pushing in all the way to the doorstep, where it rests, impatient. It is the house where James Safechuck, one of the two men at the center of Leaving Neverland, an HBO documentary, grew up, but in a way it might as well be the Darlings’ house: “Peter Pan chose this particular house because there were people here who believed in him.”

But the Safechucks are not the only people who believe, because here is another suburban house, and here again is that seeking, searching intelligence, the camera pushing closer and closer. It is the house in Brisbane, Australia, where the other subject of the documentary, Wade Robson, grew up. The implication is clear: Michael Jackson could have any little boy in the world; all he needed were parents who would serve up their sons to him.

The very first giant virus was discovered in a water-cooling tower in 2003. As the name suggests, giant viruses are unusually large and their genomes unusually complex, all of which went against the prevailing idea of viruses as small, simple, and primitive. Then one baffling giant virus became many, as scientists kept discovering different types: in water off the Chilean coast, in Siberian permafrost, in an Austrian sewage plant, and now in mud from a Japanese hot spring.

The newest giant virus is Medusavirus, so named because of the way it infects amoebas, single-celled organisms that commonly live in water. When Masaharu Takemura, a virologist at Tokyo University of Science, first grew microbes from the hot-spring mud in his lab, he noticed that some amoebas would die in the presence of the giant virus. The dead amoeba cells burst open. But others would shrivel and harden, which amoebas sometimes do when guarding against bacteria that also prey on them. (It’s a dangerous life out there for amoebas.)

In 1886, Clark Bell, the editor of the journal of the Medico-Legal Society of New York, relayed to a physician named Pliny Earle a query bound to be of interest to his journal’s readers: Exactly what mental illnesses can be said to exist? In his 50-year career as a psychiatrist, Earle had developed curricula to teach medical students about mental disorders, co-founded the first professional organization of psychiatrists, and opened one of the first private psychiatric practices in the country. He had also run a couple of asylums, where he instituted novel treatment strategies such as providing education to the mentally ill. If any American doctor was in a position to answer Bell’s query, it was Pliny Earle.

The first Facebook message arrived when Heather Woock was packing for vacation, in August 2017. It was from a stranger claiming to be her half sibling. She assumed the message was some kind of scam; her parents had never told her she might have siblings. But the message contained one detail that spooked her. The sender mentioned a doctor, Donald Cline. Woock knew that name; her mother had gone to Cline for fertility treatments before she was born. Had this person somehow gotten her mother’s medical history?

Her mom said not to worry. So Woock, who is 33 and lives just outside Indianapolis, flew to the West Coast for her vacation. She got a couple more messages from other supposed half siblings while she was away. Their persistence was strange. But then her phone broke, and she spent the next week and a half outdoors in Seattle and Vancouver, blissfully disconnected.

Early on a Wednesday morning, I heard an anguished cry—then silence.

I rushed into the bedroom and watched my wife, Rachel, stumble from the bathroom, doubled over, hugging herself in pain.

“Something’s wrong,” she gasped.

This scared me. Rachel’s not the type to sound the alarm over every pinch or twinge. She cut her finger badly once, when we lived in Iowa City, and joked all the way to Mercy Hospital as the rag wrapped around the wound reddened with her blood. Once, hobbled by a training injury in the days before a marathon, she limped across the finish line anyway.

So when I saw Rachel collapse on our bed, her hands grasping and ungrasping like an infant’s, I called the ambulance. I gave the dispatcher our address, then helped my wife to the bathroom to vomit.

Billions of years ago, something—perhaps the vibrations of an exploding star—jostled a cloud of cosmic gas and dust suspended in space. The cloud collapsed on itself and flattened into a spinning disk. The center grew heavy and ignited, forming our sun. The stuff that remained ricocheted, collided, and congealed. The biggest clumps of space stuff smoothed into spheres—the planets and moons. The smallest, the asteroids and comets, stayed as they were, like crumbs left over from an elaborate feast.

And right now one of those crumbs is exploding.

An asteroid named Bennu has been caught spewing particles into space—hundreds of gravel-size bits, hurtling from the surface at high speed.

The tiny explosions were spotted by a NASA spacecraft named OSIRIS-REx. The probe settled into an orbit around the asteroid in late December and noticed the first ejection within days. Over the next two months, OSIRIS-REx observed nearly a dozen of these events. And more are still being detected.

Big-agenda, partisan issues—the census, reapportionment and gerrymandering, the Second Amendment, abortion—are bearing down on the Supreme Court like a ship with black sails. I am not optimistic that a majority will defy Republican orthodoxy on any of these—and if that is correct, the Court will emerge next spring as both a very live political issue and a shadow of its former self.

Not every case is an agenda case, though. On Monday, the Court granted certiorari in four new criminal-justice cases that, by and large, lack a strong partisan valence. These cases will involve the Court doing, well, you know, law, and in particular, cleaning up some loose ends of its criminal jurisprudence.

Did I mention that they are really, really interesting?

Last Tuesday, the Justice Department charged 50 people with involvement in an elaborate scheme to purchase spots in some of the country’s top schools. The tactics described in the indictment were complex and multipronged, requiring multiple steps of deception and bribery by parents and their co-conspirators to secure their children’s admission to the schools of their choice. The plot purportedly included faking learning disabilities, using Photoshopped images to make it seem as if students played sports that they did not actually play, and pretending that students were of different ethnicities in an effort to exploit affirmative-action programs. The alleged scheme was led by a man named William Singer, who called his business venture a “side door” into college. On Tuesday, Singer pleaded guilty to all charges.

Nessa Coyle calls it “the existential slap”—that moment when a dying person first comprehends, on a gut level, that death is close. For many, the realization comes suddenly: “The usual habit of allowing thoughts of death to remain in the background is now impossible,” Coyle, a nurse and palliative-care pioneer, has written. “Death can no longer be denied.”

I don’t know exactly when my mother, who eventually died of metastatic breast cancer, encountered her existential crisis. But I have a guess: My parents waited a day after her initial diagnosis before calling my brother, my sister, and me. They reached me first. My father is not a terribly calm man, but he said, very calmly, something to this effect: “Your mother has been diagnosed with breast cancer.”
