Two years ago, Desmond Hughes heard so many of his favorite podcasters extolling AirPods, Apple’s tiny, futuristic $170 wireless headphones, that he decided they were worth the splurge. He quickly became a convert.

Hughes is still listening to podcasters talk about their AirPods, but now they’re complaining. The battery can no longer hold a charge, they say, rendering them functionally useless. Apple bloggers agree: “AirPods are starting to show their age for early adopters,” Zac Hall, an editor at 9to5Mac, wrote in a post in January, detailing how he frequently hears a low-battery warning in his AirPods now. Earlier this month, Apple Insider tested a pair of AirPods purchased in 2016 against a pair from 2018, and found that the older pair died after two hours and 16 minutes. “That’s less than half the stated battery life for a new pair,” the writer William Gallagher concluded.

When an ocean sunfish washed ashore in Australia a few days ago, the people who found it couldn’t help but gawk. The ocean sunfish is fundamentally bizarre, and the weirdest thing about it isn’t the teeth in its throat. It isn’t the way it plays dead on the ocean surface. It isn’t even the way its googly eyes make it perpetually look as if it’s just realized it left the stove on at home.

The strangest thing about an ocean sunfish, at least to Natasha Phillips, is its shape. Phillips, who studies the creatures at Queen’s University Belfast, called them a “giant pancake of a fish,” because they can grow to more than 5,000 pounds. Essentially, ocean sunfish look as if somebody began building a fish, added enormous vertical fins just behind its head, and then started laughing too hard to continue. And for scientists, these fish, with their unusual shape and inscrutable life, remain a “big bag of mysteries,” Phillips says.

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.

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 that he couldn’t stay silent in the face of President Donald Trump’s recent spate of attacks on the late senator.

He told me that 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.”

Less than a week after a gunman killed 50 people inside two mosques in Christchurch, New Zealand, the eyes of the world have focused on the country’s leader as she has sought to unify her reeling country.  

Prime Minister Jacinda Ardern has called for a global fight against racism, said that her government will examine what role social media played in the carnage, and on Thursday announced a ban on semiautomatic weapons and assault rifles, the kinds of arms the suspect used in the attack. As if following the lead of the prime minister, New Zealanders publicly consoled one another, will stand for two minutes of silence on Friday, and will broadcast the Islamic call to prayer across the nation.

For those bombarded into numbness by headlines in the United States, which is convulsed by partisan politics, or Britain, paralyzed over Brexit, New Zealand’s response has been marked for the unity it has sought to foster. Beyond policy prescriptions, local communities have honored the dead while Ardern has taken on the role of national healer, visiting the mosques concerned; stopping for long, emotional hugs with the grieving; and admitting her own struggles along the way. On Wednesday, for example, she visited a school that lost two pupils in the shootings. A student raised her hand and asked Ardern the one question the prime minister had not yet been publicly asked: “How are you?”

It is a truth universally acknowledged among virologists that a single virus, carrying a full set of genes, must be in want of a cell. A virus is just a collection of genes packaged into a capsule. It infiltrates and hijacks a living cell to make extra copies of itself. Those daughter viruses then bust out of their ailing host, and each finds a new cell to infect. Rinse, and repeat. This is how all viruses, from Ebola to influenza, are meant to work.

But Stéphane Blanc and his colleagues at the University of Montpellier have shown that one virus breaks all the rules.

Faba bean necrotic stunt virus, or FBNSV for short, infects legumes, and is spread through the bites of aphids. Its genes are split among eight segments, each of which is packaged into its own capsule. And, as Blanc’s team has now shown, these eight segments can reproduce themselves, even if they infect different cells. FBNSV needs all of its components, but it doesn’t need them in the same place. Indeed, this virus never seems to fully come together. It is always distributed, its existence spread between capsules and split among different host cells.

Donald Trump is not well. Over the weekend, he continued his weird obsession with a dead war hero. This time, his attacks on John McCain came two days after the anniversary of McCain’s release from a North Vietnamese prison camp. He tweeted this:

Spreading the fake and totally discredited Dossier “is unfortunately a very dark stain against John McCain.” Ken Starr, Former Independent Counsel. He had far worse “stains” than this, including thumbs down on repeal and replace after years of campaigning to repeal and replace!

And this:

So it was indeed (just proven in court papers) “last in his class” (Annapolis) John McCain that sent the Fake Dossier to the FBI and Media hoping to have it printed BEFORE the Election. He & the Dems, working together, failed (as usual). Even the Fake News refused this garbage!

When Alex, now a high-school senior, saw an Instagram account he followed post about something called QAnon back in 2017, he’d never heard of the viral conspiracy theory before. But the post piqued his interest, and he wanted to know more. So he did what your average teenager would do: He followed several accounts related to it on Instagram, searched for information on YouTube, and read up on it on forums.

A year and a half later, Alex, who asked to use a pseudonym, runs his own Gen Z–focused QAnon Instagram account, through which he educates his generation about the secret plot by the “deep state” to take down Donald Trump. “I was just noticing a lack in younger people being interested in QAnon, so I figured I would put it out there that there was at least one young person in the movement,” he told me via Instagram direct message. He hopes to “expose the truth about everything corrupt governments and organizations have lied about.” Among those truths: that certain cosmetics and foods contain aborted fetal cells, that the recent Ethiopian Airlines crash was a hoax, and that the Christchurch, New Zealand mosque shootings were staged.

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.

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.
