Unreasonable

The nearness of bees, and of other things that agitate most people, calms me. My father had three daughters and he ate watermelon with slices of cheese on the porch and he said once, over watermelon, that he was very lucky to have three girls: one beautiful, one kind, and one intelligent. Classification is a laudable scientific instinct. The ways in which the labelling and sorting don’t quite work are the glory of the process, a form of inquiry through which you catch sight of your errors and then reconsider, revise, or dispose of your categories. My father’s fairy-tale pronouncement was many years ago now. I have only two daughters: an industrious, loving, and optimistic twenty-one-year-old and a funny, joyful, and resilient ten-year-old. Maybe I have a third daughter: my work. (...)

The head of the lab, Bogdan, moved here from Serbia a quarter century ago. He grows peppers in tomato tins on his office windowsill, and he has gathered us to discuss what he has termed the current macro-environment. It has been decreed, he tells us, that we must turn away three of the five Ph.D. candidates we’ve accepted. The federal funding for the Bee Diversity and Native Pollinator Surveys has been cancelled, though there is still state-level funding. The funding for the Sub-Saharan Pollinator Project is frozen, not cancelled, but it is unlikely to be unfrozen in time for us to make use of the hundred-and-seventy-seven bee boxes currently in the field, in anticipation of the late spring and summer. The project on the diversity and frequency of pathogens in wild solitary bees—which is funded mostly through the Department of Agriculture—is also on hold, even though hundreds of the bees in question have already been tagged with tiny radio trackers. Bogdan has made an emergency application to the Alexander von Humboldt Foundation, but—he throws up his hands. What do people think?

The discussion topics that follow include but are not limited to: petitions as efficient ways for the F.B.I. to generate target lists; the importance of keeping mum; the importance of speaking out; the weakness and careerism of Democrats; being in the Ukrainian Girl Scouts and getting dropped off in the woods with three other fourteen-year-olds for three days, without food; a nephew who is a television cameraman for a news show.

That a collaborative hive is the essence of bee-ness is a common misconception. Not all species of bees are social. But it’s true that the majesty of honeycomb architecture, the future-oriented labor of transforming nectar into honey, even the decadence of male bees doing nothing much other than lounging about like upper-class Romans at a bathhouse and occasionally interrupting this to lunge at a queen—people like that stuff. They see (with reasonable accuracy) a functioning, harmonious community, a golden reflection of human potential. O.K. But, of the twenty thousand or so species of bees, about eighteen thousand are solitary. None of the solitary bees make honey. Some live underground. Solitary bees also merit interest, study, respect, etc., and it’s not because I’m disconsolate that I mention them.

Bogdan concludes the meeting by extending to me a special thank-you for speaking with the spring intern. I have not spoken with the spring intern, I tell him. Bogdan tells me that this is an advance thank-you and that I will be telling the spring intern that there is no longer a spring internship. Why me? I ask. Bogdan says that he drew my name from a jar containing numerous names.

When I open my laptop after the meeting, a cartwheeling panda crosses the screen, followed by a smiling stick figure wearing a hat. My ten-year-old daughter’s iPad has an on-again, off-again relationship with my laptop. I click and accept and manage and agree, and this process reveals that she has been playing an online game themed around wolves, the base game of which includes eighty-four achievements. In-app purchases can unlock up to a hundred and twenty-three achievements. The goals of the players are to take over territory and raise pups, and if you can get other players to howl all together—it’s a coöperative game—then your stamina increases. There are gems, stars, sidekicks, food caches, a wolf store run by gnomes, and a player named M who does not seem to be ten years old—or am I being paranoid and projecting urban myths about the ubiquity of canny pedophiles? My daughter has achieved a forty-four-day streak, during which she played for a hundred and seventy-one hours. She has Violet Tundra Wolf status, which is eleven tiers below Spirit of Cave Wolf, a Pleistocene-era wolf species now extinct.

So that explains it.

These past five weeks, this daughter—the funny, joyful, resilient one—has been slumping around saying that she needs more time to relax. Before, if you asked her how basketball practice was, she would say it was great, or awesome. If you said it was time to leave for robotics, she would say we should hurry because she didn’t want to be late. She would ask for yarn or tracing paper, she would assemble her figurines into battle scenes, and for my birthday she gave me a drawing of “what you would look like if you were a cat.” Then this turn: spending more time in her room with the door closed, saying she is desperate for peace and quiet; telling me, after she came along to a lab potluck, that I owed her majorly. (We have potlucks on the first Friday of the month. She usually loves them, on account of the reliable presence of homemade iced sugar cookies with silver sprinkles, and also because Bogdan asks her questions about her “studies,” as he calls them.) I interpreted her behavioral shift as an indication of a rise in whatever hormone it is that rises in girls around this time. My aversion to primate biology is strong. A mind must economize. Re the wolf app, however, I am not unfamiliar with the mood- and priority-altering powers of addiction. (...)

When I pick her up from school and ask her about the wolf app, she says she will delete it. She says it right away. She doesn’t argue in favor of keeping the game. She must be relieved by this intervention. I promise, Mom, she says. O.K., I should have remembered that this girl is funny, joyful, and resilient. When she was three, and we were in the gift shop of a small zoo, I told her she could choose one stuffed animal, and she chose a plush largemouth bass. Humans have what are termed K-selected reproductive strategies, which means: our young grow slowly, there are few of them, they are heavily invested in by their parents, and they have long life spans. A queen bee, in contrast, will lay two thousand eggs, but there’s little attention given to any one of her young. We would usually term this an r-selected reproductive strategy—the opposite of a K-selected reproductive strategy—though more than half survive, as the larvae are fed by their older sisters. Compare this with a largemouth bass, who lays tens of thousands of eggs, of which only a small fraction of one per cent become adults. The K and r categories are hazy, imperfect.

Many people are bored by this kind of information, I know. But my ten-year-old, historically, loves such things.

When we get home, the twenty-one-year-old is lying on the sofa, in the same position she was in this morning—apparently, although I did not diagram it—but there are two seltzer cans on the ground near her and the room smells like coconut-mango smoothie. That’s O.K. Although some worker bees leave the nest seventeen times a day and others only once or twice, the so-called lazy bees ultimately bring in about the same amount of nectar as the others. The thinking is that it’s metabolically expensive to be intelligent, so the more intelligent bees tire quickly, but when they do venture out, they are very good at finding nectar, and after that they lie low for the remainder of the day. That’s one idea, anyhow. It doesn’t cast a flattering light on me. My work ethic is that of the dim bees.

My routine these days is to drop off the ten-year-old at home with the twenty-one-year-old and then return to the lab. You could play Boggle, I suggest, as I leave. I am already thinking about my bees.

I’m teaching a subset of them to overcome a two-step obstacle to obtaining a sugar reward. They might be able to figure out one step on their own, but a sequence of steps—someone has to teach them that, unless they’re geniuses, I suppose. What I want to see is if bees to whom I haven’t taught the two-step trick will be able to learn it by watching their trained peers—whether bees can pass on ideas among themselves, and across generations. Whether they have culture, like crows do. I mean, I myself know that bees have inner lives and personalities and culture. But I’m trying to persuade other people to see them that way. I can cite much supporting evidence, some of it old, some of it generated by our lab’s research. It’s not only that individual bees have distinct foraging habits and varying problem-solving abilities. Bees even have optimism and pessimism (I would argue). If a bee has a bad experience, like being shaken in a jar, that bee is less likely to pursue a treat in situations where there’s a fifty-fifty chance of getting what it wants. Untraumatized bees are more likely to take a chance. This remarkable work came from England, a place with, I think, a no-nonsense ethology culture. Spend enough time with bees and, if you are open-minded—if you are sufficiently possessed of true scientific spirit—you begin to see them as feeling individuals. Bogdan, who researches bee visual processing and bee intelligence, anesthetizes bees before dissection as a matter of protocol, though he is not required to by the Institutional Animal Care and Use Committee. He respects them, as beings.

It is almost seven o’clock by the time I return home. The twenty-one-year-old is talking on the phone, and the ten-year-old is asleep on the sofa, her iPad clutched in her hands, her mouth slightly open. I see that she has played another hundred and twenty-seven minutes. I delete the app. I find a category called Games and Entertainment, and I delete every single game and entertainment, and I activate a timer lock that makes the iPad unusable for anything except reading for twenty-three hours and fifty-nine minutes a day. I am angry and frightened. These are drugs we’re dealing with. I download and print opinion pieces by people who have designed addictive video games and who say they would never, ever let their children use them.

The loudness of the printer gets the twenty-one-year-old off the sofa. She says she doesn’t want to hurt my feelings but she needs to be honest with me, honest about the kind of difficulties I have imposed upon her. For example, I never taught her how to cook or iron or help with dishes after supper, and it is this lack of basic grownup skills that caused her to lose the one person on the planet who understood her, the one person who was like her, who appeared normal but who on the inside was an alien. There are other aliens, but she is not compatible with them, because they look weird and act weird; their weirdness isn’t private, like hers is, and his is. She is also upset with me because when she was in the eighth grade I showed her a video of the bird-of-paradise courting ritual, and that gave her a really distorted understanding of what to expect from love, and what to expect of herself, and it just generally got her started in life on the wrong foot. But it was O.K., I was only human, and she wasn’t going to be one of those people who devote a lifetime to thinking through how their mothers failed them.

Thatta girl, I want to say. I can be clear-sighted and tough, too, even if I’m not a Serb. I would never label one daughter as beautiful and one as kind and one as intelligent, because my culture is not my dad’s. But if I were to hear such a pronouncement about my girls, I would know that my older daughter was the one being categorized as beautiful. This quality has hobbled her; in effect, it has blunted the development of compensatory strengths. In any case, I’m focussed on the ten-year-old. I wake her up.

You go to your room for half an hour, right now, until I tell you when the time is up, I say, like my dad used to. And, while you’re up there, I’d like you to read these. I give her the printouts of the articles about how video games are drugs. If she’s old enough to do drugs, she’s old enough to read about drugs. I’m not punishing you, I tell her. I’m giving you a chance to be alone. Being alone can be restorative. This, too, is something I learned from my dad. (...)

After half an hour has passed, I tell the ten-year-old she can leave her room. She does so without comment.

The next morning, she opens her purged iPad while eating a raspberry Popsicle for breakfast. She glances up at me. She sees what I’ve wrought, the virtual scorched earth, but she won’t acknowledge it. There was nothing else to eat in the house, she says of her Popsicle. When I mention that there are oranges, she tells me that I picked the wrong oranges, the ones that aren’t sweet, and that I am always buying her the wrong size shoes, too, they are never comfortable, and she hadn’t wanted to say anything before but now she needs to tell me, and also do I remember the time with her ingrown toenail that I said would heal itself and it didn’t heal itself, it got worse and worse, and do I remember when I had her come out to the field when bee swarms were happening, to learn, and it was awful, and also that time I told her to hurry across the street and there was a bus coming and she could have been killed?

It is wrong to think of bees as lacking inner lives, dreams, fears, anger. I am thinking primarily of the worker bees, which is to say the female bees, because they are the ones who set out every day. When one meets a bee out in the world, as opposed to in the hive, it’s almost always a female. For this reason, most of what we know about bees is about female bees, because they are easier to see, easier to study. Male bees likely have inner lives as well—they may also be dim or bright, optimistic or pessimistic—but we have so little observational data about them. Some researchers have held on to the idea that they are simple layabouts who exist only to fertilize a queen. Myself, I agree with those who say that’s a metabolically very expensive approach to maintaining a cache of genetic variance. After mating season, male bees’ sisters no longer provide them much nectar; they let their brothers waste away, and at a certain point escort them to the hive’s entrance and toss them out like old loaves. Something is missing in our understanding of the males. That seems clearer to me than ever. And yet the abundance of our knowledge about the females has only increased their ineffability. (...)

When the class ends, someone in a cantaloupe hoodie is waiting for me outside the seminar room. It’s my twenty-one-year-old’s former boyfriend, the alien. He shakes my hand and says he isn’t angry with me. But, at the same time, I am angry, he adds. He says he is not freaked out but also is freaked out, and that he isn’t saying I’m responsible but also, if someone is responsible, it would be me.

You’re not a quantitative thinker, are you? I want to say to him. As I walk him over to my office, I am thinking that why anyone finds anyone else attractive is more mysterious than is usually acknowledged. My beautiful daughter! The cantaloupe alien sits down on the sofa, and I sit behind my desk. He says that he ran into my daughter at the taco place, and that seemed normal, and he cares for her as a person. And then he saw her at the all-night ninepin-bowling place, and he still thought, Well, maybe that happens. And then he saw her on a bench outside his cousin’s apartment. That’s when he searched his backpack. It was like one of those Swedish thriller-horror films, he says. He reaches into his pocket and unwraps from aluminum foil a very small coppery coil attached to a plastic rectangle.

That’s curious, I say. It’s a small radio tracker. I had lunch a few years back with the man who designed this particular model. He had French onion soup and didn’t use a napkin. I have superglued thousands of his trackers onto the backs of chilled, sleepy bees before sending them back out into their world. This must be a mistake or confusion, I say. There are so many of these lying around the house, I say. The coil might have caught on his hoodie. Or his shoelace. Or was packed into his bag by accident along with a book, or a sock, or a decorative charm.

Yeah, I don’t think so, he says.

He’s chewing on the aglet of his hoodie’s drawstring like a preschooler. He closes his hand over the tracker. I’m thinking, Has my daughter tracked that he’s right here right now? She will be so angry with me if so.

The alien is saying that he was raised not to get police involved in stuff like this but rather to work things out person to person, through communication, compassion, and understanding.

Yes, I say to him, it’s very commendable that he has come to see me. And it is! Meanwhile, he is looking at the three-monkeys figurine on my desk. You like the monkeys, I remark, deliberately not calling them what they really are, which is chimpanzees. He tells me that he’s seen monkeys playing poker, but not this.

O.K., I say, getting up. Thank you so much for coming by. Let me see if I can get to the bottom of this. I take the tracker—the evidence—from him.

Scientists Unlock Secret to Venus Flytrap’s Hair-Trigger Response

To trap its prey, the Venus flytrap sends rapid electrical impulses, which are generated in response to touch or stress. But the molecular identity of the touch sensor has remained unclear. Japanese scientists have identified the molecular mechanism that triggers that response and have published their work in a new paper in the journal Nature Communications.

As previously reported, the Venus flytrap attracts its prey with a pleasing fruity scent. When an insect lands on a leaf, it stimulates the highly sensitive trigger hairs that line the leaf. When the pressure becomes strong enough to bend those hairs, the plant will snap its leaves shut and trap the insect inside. Long cilia grab and hold the insect in place, much like fingers, as the plant begins to secrete digestive juices. The insect is digested slowly over five to 12 days, after which the trap reopens, releasing the dried-out husk of the insect into the wind.

In 2016, Rainer Hedrich, a biophysicist at Julius-Maximilians-Universität Würzburg in Bavaria, Germany, led the team that discovered that the Venus flytrap could actually "count" the number of times something touches its hair-lined leaves—an ability that helps the plant distinguish between the presence of prey and a small nut or stone, or even a dead insect. The plant detects the first "action potential" but doesn't snap shut right away, waiting until a second zap confirms the presence of actual prey, at which point the trap closes. But the Venus flytrap doesn't close all the way and produce digestive enzymes to consume the prey until the hairs are triggered three more times (for a total of five stimuli).

And in 2023, scientists developed a bioelectronic device to better understand the Venus flytrap's complex signaling mechanism by mapping how those signals propagate. They confirmed that the electrical signal starts in the plant's sensory hairs and then spreads radially outward with no clear preferred direction. And sometimes the signals were spontaneous, originating in sensory hairs that had not been stimulated.

Glowing green

This latest research is an outgrowth of a 2020 paper detailing how the Japanese authors genetically altered a Venus flytrap to gain important clues about how the plant's short-term "memory" works. They introduced a gene for a calcium sensor protein called GCaMP6, which glows green whenever it binds to calcium. That green fluorescence allowed the team to visually track the changes in calcium concentrations in response to stimulating the plant's sensitive hairs with a needle. They concluded that the waxing and waning of calcium concentrations in the leaf cells seem to serve as a kind of short-term memory for the Venus flytrap, though precisely how calcium concentrations work with the plant's electrical network remained unclear.

Hawaiʻi Loves ‘Genki Balls’. New Studies Say They Don’t Work

A new two-year research project found the balls not only were ineffective, they might make water quality worse. Supporters of the effort don’t believe it.

In the past six years, several thousand elementary school students and other volunteers have tossed over a quarter million tennis ball-sized globs of soil, molasses and rice bran into the Ala Wai Canal in a valiant effort to help clean Hawaiʻi’s most notoriously polluted urban waterway.

The goal is to get those globs, known as “genki balls,” to release special sludge-eating microbes into the Waikīkī canal’s murky depths and boost its water quality. Since the effort started, canoe paddlers and others have at times observed clearer water and more fish. They’ve even spotted the occasional monk seal and an eagle ray.

But new research from Hawaiʻi Pacific University done on Oʻahu’s Windward side casts doubt on whether the genki balls actually led to any of that improvement — or if the novel approach that inspired the community is too good to be true. (...)

The balls, according to HPU Associate Professor Olivia Nigro and Assistant Professor Carmella Vizza, did nothing to improve water quality in the marsh canal. And in the aquarium tanks, the microbes the balls were supposed to release failed to appear in any meaningful way, the researchers said, plus the water quality actually got worse.

Specifically, phosphate levels were almost 20 times higher in the tanks with the balls than in tanks without them, Vizza said, and oxygen levels in the tanks with the balls fell by about 50%.


The nonprofit that organizes those cleanups, Genki Ala Wai Ball Project, is firmly pushing back against the research, saying insufficient genki material was used and its ball tosses into the Ala Wai remain effective. Yet one of the project’s leaders sold the balls used in the HPU study and recommended how the researchers should use them.

The HPU ecologists who completed the study don’t want to dampen any of the community enthusiasm. But far more rigorous study of the Ala Wai is needed, they say, to know exactly how the genki balls are impacting water quality there, if at all. (...)

If We Do This, We Can Do Anything

The Ala Wai, a 1.5-mile canal that developers carved across Waikīkī in the 1920s to sell real estate, has long been a stark symbol of how much urban runoff is affecting Hawaiʻi’s fragile watersheds. (...)

It now bears the brunt of storm debris from Hawaiʻi’s densest and most heavily populated watershed, in the heart of Honolulu. For decades, state officials have prohibited anyone from fishing or swimming in its waters.


In one high-profile 2006 incident, an Oʻahu man who fell in the Ala Wai died of “massive bacterial infection” following weeks of heavy rain across the state. Canoe clubs and high school teams regularly paddle up and down the canal and do their best not to huli, or flip over, into its murky waters.

... the Genki Ball Ala Wai Project launched with a goal of making the canal safe for swimming and fishing within seven years by deploying 300,000 balls. Genki translates to “health” or “energy” in English.

The key ingredient baked into every dry, cured ball tossed in the water is a trademarked substance called “EM,” short for “effective microorganisms.”

It was pioneered in the early 1980s by a horticulture professor in Okinawa, Japan, who combined naturally occurring yeasts and bacteria to help boost farm crop yields. Since then, people also found that they could take it to improve digestion and gut health.

Can This Tree Still Save Us?

ʻUlu, bia, uru, mā: Breadfruit has been lauded as a climate-resilient solution to world food security. That’s not proving true in the Marshall Islands, where some have relied on it for centuries.

A breadfruit tree stands in the middle of Randon Jother’s property, its lanky trunks feeding a network of sinewy limbs. The remnants of this season’s harvest weigh heavy on its branches. Its vibrant leaves and football-sized fruit may appear enormous to the untrained eye, but Jother is concerned.

They used to be longer than his hand and forearm combined. He points to his bicep, to show how fat they once were. Now they’re small and malformed by most people’s standards here in the Marshall Islands. Mā, the Marshallese term for breadfruit, used to ripen in May. Now they come in June, sometimes July.
 
It’s been headed this way for the past seven years, Jother says as he toes the tree’s abundant leaf litter. It’s a concerning development on this uniquely agricultural and fertile part of Majuro Atoll, home to the country’s highest point: eight feet above sea level.

“I think it’s the salt,” Jother says. His home is less than 100 yards from Majuro lagoon, a body of seawater that threatens to overflow onto the land during a storm or king tide, which over the past decade years has happened several times in Majuro and across the islands. The Pacific Ocean also threatens to salt the island’s ever precious groundwater, which Jother says is already happening. When he showers, he can feel it in his hair, on his skin.

The record heat waves, massive droughts and an increasing number of unpredicted and intense weather events don’t help his trees either.

Most assume the assailant is climate change, to which researchers and experts have said the Indigenous Pacific crop would be almost immune — a potential salve for the world’s imperiled food system. For places like Hawaiʻi, they have predicted breadfruit growing conditions may even get better.

But here, on Majuro and throughout the Marshall Islands, the future appears bleak for a crop that has helped sustain populations for more than 2,000 years.
 

Rice has overtaken the fruit’s status as the preferred staple over the past century, along with other ultraprocessed imports, a change that feeds myriad health complications, including outsized rates of diabetes, making non-communicable diseases the leading cause of death across these islands.

The diseases are a Pacific-wide issue, one Marshall Islands health and agriculture officials are eager to counter with a return to a traditional diet. Climate change is working against them. (...)

Mā is part of an important trinity for the Marshall Islands, which also includes coconut (ni) and pandanus (bōb), that made their way to the islands’ shores on Micronesian seafarers’ boats somewhere between 2,000 and 3,000 years ago.

Six varieties are most common in the Marshall Islands, though at least 20 are found throughout the islands. Hundreds more breadfruit types can be found in the Pacific, tracing back to the breadnut, a tree endemic to the southwestern Pacific island of New Guinea.

The tree provided security for island populations, requiring little upkeep to offer abundant harvests. Each tree produces anywhere from 350 to 1,100 pounds of breadfruit a year, with two harvest seasons. Every tree produces half a million calories in protein and carbohydrates.
 
Like many Pacific island countries, the mā tree’s historic uses were diverse. Its coarse leaves sanded and smoothed vessels made with the tree’s buoyant wood. Its roots were part of traditional medicine. The fruit was cooked underground and roasted black over coals. And it was preserved, to make bwiro, a tradition that survives through people like Angelina Mathusla.

For Mathusla, who lives just over a mile from farmer Jother, making bwiro is a process that comes with every harvest.

The process begins with a pile of petaaktak, a variety of breadfruit common around Majuro and valued for its size and lack of seeds. On this occasion, a relative rhythmically cleaves the football-sized mā in half with a machete, then into smaller pieces, before tossing them into a pile next to a group of women. Some wear gloves to avoid the sticky white latex that seeps from the fruit’s dense, white flesh, used by their forebears to seal canoes or catch birds.

Mā trees use that latex to help heal or protect themselves against diseases and insects. The tree’s adaptation to the atolls and their soils has traditionally been partly thanks to symbiotic relationships with other flora. (...)

A Shallow Body Of Research

Four framed photographs hang on a whitewashed wall of Diane Ragone’s Kauaʻi home. Two black-and-white photos, taken by her late videographer husband, show Jimi Hendrix and Jerry Garcia playing guitar on stage. The other two are of breadfruit.

Now in the throes of writing a memoir, of sorts, Ragone is revisiting almost 40 years of records — photos and videos, and journal entries, some of which leave her asking “Damn, why was I so cryptic?”

But Ragone’s research, since her arrival to Hawaiʻi from Virginia in 1979, forms the bedrock of most modern research into the tree’s history and its survival throughout the Pacific. The most obvious example spans 10 acres in Hāna, on Maui, where more than 150 cultivars of the fruit Ragone collected thrive at the National Tropical Botanical Garden’s Kahanu Garden.

Less obvious is how her work has helped researchers like Noa Kekuewa Lincoln track the plant’s place in global history and the environment. Lincoln, who says “Diane’s kind of considered the Queen of Breadfruit,” has been central to more recent research into how the plant will survive in the future.

Together with others, they act as breadfruit evangelists, promoting the crop as a poverty panacea and global warming warrior — a touchstone for Pacific islanders not only to their past but a more sustainable future.

Ragone, as the founding director of the 22-year-old Breadfruit Institute, helped distribute more than 100,000 trees around the world, to equatorial nations with poverty issues and suitable climes, like Liberia, Zambia and Haiti. But it all started in Hawaiʻi with just over 10,000 young breadfruit.
 
In some places, rising temperatures and changes in rainfall will actually help breadfruit, according to research from Lincoln and his Indigenous Cropping Systems Laboratory, which assessed the trees’ performance under different climate change projections through 2070.

Running climate change scenarios on 1,200 trees across 56 sites in Hawaiʻi, Lincoln’s lab found breadfruit production would largely remain the same for the next 45 years.

“Nowhere in Hawaiʻi gets too hot for it,” Lincoln says. “Pretty much as soon as you leave the coast, you start getting declining yields because it’s too cold.”

Compare breadfruit to other traditional staples — rice, wheat, soybeans, corn. The plant grows deep roots and lives for decades, requires little upkeep or annual planting, resists most environmental stressors and can withstand high temperatures.

Few nations know the urgency of climate change better than the Marshall Islands, its islands and atolls a bellwether for how heat, drought, intense and sporadic natural disasters and sea level rise can upend lives.

The trees can even survive some saltwater intrusion, according to Lincoln’s research. But a consistent presence of salt is another matter, attacking the roots and making trees unable to absorb freshwater and nutrients. As roots rot, leaves and fruit die.

“The salinity,” Ragone says, before letting out a sigh. “How do you even address the salinity issue?”.


Marshall Islands government officials have turned to the International Atomic Energy Association for help, asking its experts about using nuclear radiation to create mutant hybrids of the nation’s most important crops — giant swamp taro, sweet potatoes and, of course, breadfruit.

The technique has been used for almost a century by the atomic association and Food and Agriculture Organization of the United Nations, predominantly on rice and barley, never on breadfruit or for a Pacific nation.

They have their work cut out for them. To find a viable candidate, immune to salty soils and heat, about 2,000 plants would need to be irradiated, according to Cinthya Zorrilla of the atomic energy association’s Centre of Nuclear Techniques in Food and Agriculture. One of those plants, once mutated, might exhibit the desired traits. (...)

Even if those obstacles were overcome, it wouldn’t be a quick fix. Hybridizing plants through radiation can take about 10 years, Zorrilla says, with a need to compare, contrast and correlate results from labs and field plots and laboratories. For breadfruit, the timeframe may be even longer.

“It’s really complicated,” Zorilla says. “All this is a huge investment, in monetary terms and also in time.”

Warming Seas Threaten Key Phytoplankton Species

For decades, scientists believed Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic bacterium, which forms the foundation of the marine food web and helps regulate the planet’s climate, will decline sharply as seas heat up.

A study published Monday in the journal Nature Microbiology found Prochlorococcus populations could shrink by as much as half in tropical oceans over the next 75 years if surface waters exceed about 82 degrees Fahrenheit (27.8 Celsius). Many tropical and subtropical sea surface temperatures are already trending above average and are projected to regularly surpass 86 degrees Fahrenheit (30 Celsius) over that same period.

“These are keystone species — very important ones,” said François Ribalet, a research associate professor at the University of Washington’s School of Oceanography and the study’s lead author. “And when a keystone species decreases in abundance, it always has consequences on ecology and biodiversity. The food web is going to change.”

These tiny organisms hold a vital role in ocean life

Prochlorococcus inhabit up to 75% of Earth’s sunlit surface waters and produce about one-fifth of the planet’s oxygen through photosynthesis. More crucially, Ribalet said, they convert sunlight and carbon dioxide into food at the base of the marine ecosystem.

“In the tropical ocean, nearly half of the food is produced by Prochlorococcus,” he said. “Hundreds of species rely on these guys.”

Though other forms of phytoplankton may move in and help compensate for the loss of oxygen and food, Ribalet cautioned they are not perfect substitutes. “Evolution has made this very specific interaction,” he said. “Obviously, this is going to have an impact on this very unique system that has been established.”

The findings challenge decades of assumptions that Prochlorococcus would thrive as waters warmed. Those predictions, however, were based on limited data from lab cultures. For this study, Ribalet and his team tested water samples while traversing the Pacific over the course of a decade.

Over 100 research cruises — the equivalent of six trips around the globe — they counted some 800 billion individual cells taken from samples at every kilometer. In his lab at the University of Washington, Ribalet demonstrated the SeaFlow, a box filled with tubes, wires and a piercing blue laser. The custom-built device continuously pulls in seawater, which allowed the team to count the microbes in real time. “We have counted more Prochlorococcus than there are stars in the Milky Way,” Ribalet said.

Experts warn of ‘big consequences’

Paul Berube, a research scientist at Massachusetts Institute of Technology who studies Prochlorococcus but was not involved in the work, said the breadth of data is “groundbreaking.” And he said the results fit with what is known about the microbe’s streamlined genome, which makes it less adaptable to rapid environmental changes.

“They’re at the very base of the food web, and they feed everything else — the fish eat the things that eat the phytoplankton and we eat the fish,” he said. “When changes are being made to the planet that influence these particular organisms that are essentially feeding us, that’s going to have big consequences.”

To test whether Prochlorococcus might evolve to withstand hotter conditions, Ribalet’s team modeled a hypothetical heat-tolerant strain but found that even those would “not be enough to fully resist the warmest temperature if greenhouse emissions keep rising,” Ribalet said.

He stressed that the study’s projections are conservative and don’t account for the impacts of plastic pollution or other ecological stressors. “We actually tried to put forth the best-case scenario,” Ribalet said. “In reality, things may be worse.”

According to the latest annual Nature Index, which tracks research institutions by their contributions to leading science journals, the single remaining U.S. institution among the top 10 is Harvard, in second place, far behind the Chinese Academy of Sciences. The others are:
  • The University of Science and Technology of China
  • Zhejiang University
  • Peking University
  • The University of Chinese Academy of Sciences
  • Tsinghua University
  • Nanjing University
  • Germany’s Max Planck Society
  • Shanghai Jiao Tong University
A decade ago, C.A.S. was the only Chinese institution to figure in the top 10. Now eight of the 10 leaders are in China. If this does not constitute a Sputnik moment, it is hard to imagine what would.

But if America’s response to Sputnik reflected a nation united in its commitment to science and determined to invest in the country’s intellectual potential, we see in our response to China today a bitterly divided, disoriented America. We are currently governed by a leader indifferent to scientific consensus if it contradicts his political or economic interests, hostile to immigrants and intent on crippling the research universities that embody our collective hope for the future. The menace now is within. And with very few exceptions, the leaders of American universities have done little more than duck and cover.

Human Exceptionalism

A terrific new book, The Arrogant Ape, by the primatologist Christine Webb, will be out in early September, and I don’t think a nonfiction book has affected me more, or taught me more, in a long time. It’s about human exceptionalism and what’s wrong with it.

It also has illuminating things to say about awe, humility, and the difference between optimism and hope. (...)

Here’s my review:

Here are some glimpses from the review:
***
Christine Webb, a primatologist at New York University, is focused on “the human superiority complex,” the idea that human beings are just better and more deserving than are members of other species, and on the extent to which human beings take themselves as the baseline against which all living creatures are measured. As Hamlet exclaimed: “What a piece of work is man! How noble in reason!… The paragon of animals!” In Webb’s view, human exceptionalism is all around us, and it damages science, the natural environment, democratic choices, and ordinary (human) life. People believe in human superiority even though we are hardly the biggest, the fastest, or the strongest. Eagles see a lot better than we do. Sea sponges live much longer. Dolphins are really good at echolocation; people are generally really bad at it. And yet we keep proclaiming how special we are. As Webb puts it, “Hamlet got one thing right: we’re a piece of work.” [. . .]

I have two Labrador Retrievers, Snow and Finley, and on most days, I take them for a walk on a local trail. Every time, it is immediately apparent that they are perceiving and sensing things that are imperceptible to me. They hear things that I don’t; they pause to smell things that I cannot. Their world is not my world. Webb offers a host of more vivid examples, and they seem miraculous, the stuff of science fiction.

For example, hummingbirds can see colors that human beings are not even able to imagine. Elephants have an astonishing sense of smell, which enables them to detect sources of water from miles away. Owls can hear the heartbeat of a mouse from a distance of 25 feet. Because of echolocation, dolphins perceive sound in three dimensions. They know what is on the inside of proximate objects; as they swim toward you, they might be able to sense your internal organs. Pronghorn antelopes can run a marathon in 40 minutes, and their vision is far better than ours. On a clear night, Webb notes, they might be able to see the rings of Saturn. We all know that there are five senses, but it’s more accurate to say that there are five human senses. Sharks can sense electric currents. Sea turtles can perceive the earth’s magnetic field, which helps them to navigate tremendous distances. Some snakes, like pythons, are able to sense thermal radiation. Scientists can give many more examples, and there’s much that they don’t yet know.

Webb marshals these and other findings to show that when we assess other animals, we use human beings as the baseline. Consider the question of self-awareness. Using visual tests, scientists find that human children can recognize themselves in a mirror by the age of three—and that almost no other species can do that. But does that really mean that human beings are uniquely capable of recognizing themselves? It turns out that dogs, who rely more on smell than sight, can indeed recognize themselves, if we test by reference to odor; they can distinguish between their own odor and that of other dogs. (Can you do that?) In this sense, dogs too show self-awareness. Webb argues that the human yardstick is pervasively used to assess the abilities of nonhuman animals. That is biased, she writes, “because each species fulfills a different cognitive niche. There are multiple intelligences!”

Webb contends that many of our tests of the abilities of nonhuman animals are skewed for another reason: We study them under highly artificial conditions, in which they are often miserable, stressed, and suffering. Try caging human beings and seeing how well they perform on cognitive tests. As she puts it, “A laboratory environment can rarely (if ever) adequately simulate the natural circumstances of wild animals in an ecologically meaningful way.” Suppose, for example, that we are investigating “prosociality”—the question of whether nonhuman animals will share food or cooperate with one another. In the laboratory, captive chimpanzees do not appear to do that. But in the wild, chimpanzees behave differently: They share meat and other food (including nuts and honey), and they also share tools. During hunting, chimpanzees are especially willing to cooperate. In natural environments, the differences between human beings and apes are not nearly so stark. Nor is the point limited to apes. Cows, pigs, goats, and even salmon are a lot smarter and happier in the wild than in captive environments. (...)

It would be possible to read Webb as demonstrating that nonhuman animals are a lot more like us than we think. But that is not at all her intention. On the contrary, she rejects the argument, identified and also rejected by the philosopher Martha Nussbaum, that the nonhumans animals who are most like us deserve the most protection, what Nussbaum calls the “so like us” approach. (This is also part of the title of an old documentary about Jane Goodall’s work.) Webb sees that argument as a well-meaning but objectionable form of human exceptionalism. Why should it matter that they are like us? Why is that necessary? With Nussbaum, Webb insists that species are “wonderfully different,” and that it is wrong to try to line them up along a unitary scale and to ask how they rank. Use of the human yardstick, embodied in the claim of “so like us,” is a form of blindness that prevents us from seeing the sheer variety of life’s capacities, including cognitive ones. As Nussbaum writes, “Anthropocentrism is a phony sort of arrogance.”

Salmon Farming in Alaska: 'Are You Insane?'

Raising the idea of salmon farms in Alaska, Gov. Dunleavy swims against a tide of skeptics

Amid the hubbub of President Donald Trump and Russian President Vladimir Putin’s Alaska summit last week, Gov. Mike Dunleavy, posting on social media, posed a provocative question.

“Alaska is a leader in fresh caught wild salmon. We could also be a leader in the farmed salmon industry. Why not do both instead of importing farmed salmon from Scotland?,” he wrote, sharing an article about the value of fish farming in Scotland, where Atlantic salmon are raised in net pens in the ocean. “This would be a great opportunity for Alaska.”

The answer from scientists, wild salmon advocates, restaurant people and regular salmon-eating Alaskans has come swiftly, full of alarm and often along the lines of one of the early commenters on his post, who wrote, “Are you insane?”

Love for wild salmon cuts through partisan politics. No food is more important to the state’s culture, diet, identity and economy. As such, Alaskans don’t look kindly on farmed fish. It’s tough to find it in stores and few, if any, restaurants serve it. Farming salmon and other finfish has been banned since 1990 over concerns about environmental threats to wild stocks and economic competition. But Dunleavy, who has become increasingly interested in Alaska’s food security since the pandemic, is curious about bringing in fish farms.

Last legislative session, his office introduced a bill that would authorize land-based farming of non-salmon species like trout or tilapia. That bill faced an avalanche of opposition in committee. But his recent post went further, signaling a shift feared by fisheries advocates, from a narrow focus on land-based farms to a broader look at farming salmon, the vast majority of which happens in net pens in the ocean. (...)

Dunleavy didn’t have a specific plan for how salmon in Alaska might be farmed, he said. Land-based salmon farming, something some environmental groups support, is being tried in a few markets but can be cost-prohibitive. There are concerns over open-net pens that need to be addressed, he said, as well as concerns about what species of salmon might be raised.

Salmon is the second-most popular seafood in the country, just behind shrimp, and roughly 75% to 80% of the salmon Americans eat is farmed Atlantic salmon. Atlantic salmon in the wild have almost disappeared due to overfishing and they cannot be fished commercially. Alaska provides the lion’s share of the wild salmon in the country’s fish markets. But in the world, Dunleavy pointed out, Russia provides the largest share of salmon. Farming fish might be a way for Alaska, and the U.S., to occupy a larger position in that marketplace, he said.

“What I’ve said is, basically, is the discussion worthwhile that Alaska has today, in 2025, to visit the idea of Alaska being part of that game of a new sector?” he said.

At-sea fish farming has gotten cleaner in recent decades, thanks to advances in technology and feeding practices that minimize the impacts of effluent, said Caitlyn Czajkowski, executive director of the National Aquaculture Association, a Florida-based aquaculture trade association.

“There’s a lot of things about the ocean that we know now that we didn’t know 20 years ago,” she said.

Some non-salmon operations also now farm fish that are genetically sterile, so that if they escape, they can’t mix with local populations. That technology is still under development for salmon, however. There are a number of places that used to have commercial salmon fisheries in the Atlantic region, including Maine, Canada and a number of European countries that now farm Atlantic salmon. There isn’t another place, like Alaska, where salmon farming is happening in tandem with a robust wild salmon fishery, Czajkowski said.

At Crush Bistro, a high-end restaurant in downtown Anchorage bustling with tourists this week, Rob DeLucia, owner and general manager, said he was dumbfounded by the governor’s post. Guests come into the restaurant every night and say they came to Alaska for two reasons: to see Denali and to eat wild fish, he said.

“It is crystal clear when you get a piece of salmon at a restaurant in Alaska, that thing was swimming around in the last couple of days out in the wild blue ocean, and now we’re going to have guests be like, ‘Well, is this farmed or is this wild?’” he asked.

Atlantic farmed salmon, from a culinary standpoint, is inferior in taste and texture, he said. It made no sense to promote it.

“(Dunleavy) should have his Alaskan card revoked,” DeLucia said.

Help Wanted: Unique opportunity to lead the largest state in the country, with more miles of coastline, taller mountains, more fish and game, more dreams and less reality than those other 49 pipsqueaks.
Dynamic, credible decision maker with strong personality needed to lead the second-youngest state in the nation into the future, albeit without enough money to meet all its needs.

It’s a fixer-upper job; the current employee has let a lot of things go bad, never learned to get along with co-workers, and hasn’t been working all that hard. Which means the next person has loads of opportunity to make a difference. The bar is low, but the need is high.

Applicants have plenty of time to study and do their homework; the job opens up next year.

Job candidates can use that time to think about how they will bring together disagreeable factions, confront decades-old problems, pay attention to the work at home and less attention to national media, all while winning the hearts and minds of the public — and the support of their colleagues in elected office.

Most importantly, job applicants need to tell the truth about realistic plans. The state has suffered too long with leadership that believes in crystal balls, while public services have fallen behind the eight ball.

The job pays $176,000 a year and includes free housing in a historic home in the state capital city, easy walking distance to the office that comes with a remodeled conference room, a full kitchen and reserved parking.

It’s a four-year job, which should be enough time for the right person to make a difference.

Applications are now being accepted for the job of governor of Alaska. The deadline to apply is June 1 next year. The first cut will come in the Aug. 18 primary election, with the final decision in the Nov. 4 general election.

Already, eight Republicans and one Democrat have applied for the job. By the time applications close, the list likely will exceed a baker’s dozen.

Candidates may be judged by the public on how well they can answer questions about state finances, state tax policies, school funding, social services, law enforcement, housing and the other basics of life, like water and sewage services.

The best candidates will be the ones who truly understand why a state with $82 billion in savings can seem so broke; who can explain why nonresidents who come here to work go home every two weeks without paying any taxes; why some corporations doing business in Alaska pay taxes and others don’t; why the state can’t seem to process Medicaid and food stamp applications on time; why the ferry system has shrunk and rusted away; why some cities pay for police services while others sponge off the state troopers; and why child care and children’s services come up short in the budget.

Don’t apply if you don’t want to deal honestly with the problems, and if you don’t have specific positions and proposals to share. This is not a job for vague answers, wishful thinking and fields of dreams. Remote work not allowed.

Lore of the World: Field Notes for a Child's Codex: Part 2

When you become a new parent, you must re-explain the world, and therefore see it afresh yourself.

A child starts with only ancestral memories of archetypes: mother, air, warmth, danger. But none of the specifics. For them, life is like beginning to read some grand fantasy trilogy, one filled with lore and histories and intricate maps.

Yet the lore of our world is far grander, because everything here is real. Stars are real. Money is real. Brazil is real. And it is a parent’s job to tell the lore of this world, and help the child fill up their codex of reality one entry at a time.

Below are a few of the thousands of entries they must make.


Walmart

Walmart was, growing up, where I didn’t want to be. Whatever life had in store for me, I wanted it to be the opposite of Walmart. Let’s not dissemble: Walmart is, canonically, “lower class.” And so I saw, in Walmart, one possible future for myself. I wanted desperately to not be lower class, to not have to attend boring public school, to get out of my small town. My nightmare was ending up working at a place like Walmart (my father ended up at a similar big-box store). It seemed to me, at least back then, that all of human misery was compressed in that store; not just in the crassness of its capitalistic machinations, but in the very people who shop there. Inevitably, among the aisles some figure would be hunched over in horrific ailment, and I, playing the role of a young Siddhartha seeing the sick and dying for the first time, would recoil and flee to the parking lot in a wave of overwhelming pity. But it was a self-righteous pity, in the end. A pity almost cruel. I would leave Walmart wondering: Why is everyone living their lives half-awake? Why am I the only one who wants something more? Who sees suffering clearly?

Teenagers are funny.

Now, as a new parent, Walmart is a cathedral. It has high ceilings, lots to look at, is always open, and is cheap. Lightsabers (or “laser swords,” for copyright purposes) are stuffed in boxes for the taking. Pick out a blue one, a green one, a red one. We’ll turn off the lights at home and battle in the dark. And the overall shopping experience of Walmart is undeniably kid-friendly. You can run down the aisles. You can sway in the cart. Stakes are low at Walmart. Everyone says hi to you and your sister. They smile at you. They interact. While sometimes patrons and even employees may appear, well, somewhat strange, even bearing the cross of visible ailments, they are scary and friendly. If I visit Walmart now, I leave wondering why this is. Because in comparison, I’ve noticed that at stores more canonically “upper class,” you kids turn invisible. No one laughs at your antics. No one shouts hello. No one talks to you, or asks you questions. At Whole Foods, people don’t notice you. At Stop & Shop, they do. Your visibility, it appears, is inversely proportional to the price tags on the clothes worn around you. Which, by the logical force of modus ponens, means you are most visible at, your very existence most registered at, of all places, Walmart.

Cicadas

The surprise of this summer has been learning we share our property with what biologists call Cicada Brood XIV, who burst forth en masse every 17 years to swarm Cape Cod. Nowhere else in the world do members of this “Bourbon Brood” exist, with their long black bodies and cartoonishly red eyes. Only here, in the eastern half of the US. Writing these words, I can hear their dull and ceaseless motorcycle whine in the woods.

The neighbors we never knew we had, the first 17 years of a cicada’s life are spent underground as a colorless nymph, suckling nutrients from the roots of trees. These vampires (since they live on sap, vampires is what they are, at least to plants) are among the longest living insects. Luckily, they do not bite or sting, and carry no communicable diseases. It’s all sheer biomass. In a fit of paradoxical vitality, they’ve dug up from underneath, like sappers invading a castle, leaving behind coin-sized holes in the ground. If you put a stick in one of these coin slots, it will be swallowed, and its disappearance is accompanied by a dizzying sense that even a humble yard can contain foreign worlds untouched by human hands.

After digging out of their grave, where they live, to reach the world above, where they die, cicadas next molt, then spend a while adjusting to their new winged bodies before taking to the woods to mate. Unfortunately, our house is in the woods. Nor is there escape elsewhere—drive anywhere and cicadas hit your windshield, sometimes rapid-fire; never smearing, they instead careen off almost politely, like an aerial game of bumper cars.

We just have to make it a few more weeks. After laying their eggs on the boughs of trees (so vast are these clusters it breaks the branches) the nymphs drop. The hatched babies squirm into the dirt, and the 17-year-cycle repeats. But right now the saga’s ending seems far away, as their molted carapaces cling by the dozens to our plants and window frames and shed, like hollow miniatures. Even discarded, they grip.

“It’s like leaving behind their clothes,” I tell your sister.

“Their clothes,” she says, in her tiny pipsqueak voice.

We observe the cicadas in the yard. They do not do much. They hang, rest, wait. They offer no resistance to being swept away by broom or shoe tip. Even their flights are lazy and ponderous and unskilled. And ultimately, this is what is eerie about cicadas. Yes, they represent the pullulating irrepressible life force, but you can barely call any individual alive. They are life removed from consciousness. Much like a patient for whom irreparable brain damage has left only a cauliflower of functional gray matter left, they are here, but not here. Other bugs will avoid humans, or even just collisions with inanimate objects. Not the cicada. Their stupidity makes their existence even more a nightmare for your mother, who goes armed into the yard with a yellow flyswatter. She knows they cannot hurt her, but has a phobia of moths, due to their mindless flight. Cicadas are even worse in that regard. Much bigger, too. She tries, mightily, to not pass down her phobia. She forces herself to walk slowly, gritting her teeth. Or, on seeing one sunning on the arm of her lawn chair, she pretends there is something urgent needed inside. But I see her through the window, and when alone, she dashes. She dashes to the car or to the shed, and she dashes onto the porch to get an errant toy, waving about her head that yellow flyswatter, eyes squinted so she can’t see the horrors around her.

I, meanwhile, am working on desensitization. Especially with your sister, who has, with the mind-reading abilities she’s renowned for, picked up that something fishy is going on, and screeches when a cicada comes too near. I sense, though, she enjoys the thrill.

“Hello Cicadaaaaaasss!” I get her to croon with me. She waves at their zombie eyes. When she goes inside, shutting the screen door behind her, she says an unreturned goodbye to them.

Despite its idiocy, the cicada possesses a strange mathematical intelligence. Why 17-year cycles? Because 17 is prime. Divisible by no other cycle, it ensures no predator can track them generation to generation. Their evolutionary strategy is to overwhelm, unexpectedly, in a surprise attack. And this gambit of “You can’t eat us all!” is clearly working. The birds here are becoming comically fat, with potbellies; in their lucky bounty, they’ve developed into gourmands who only eat the heads.

Individual cicadas are too dumb to have developed such a smart tactic, so it is evolution who is the mathematician here. But unlike we humans, who can manipulate numbers abstractly, without mortal danger, evolution must always add, subtract, multiply, and divide, solely with lives. Cicadas en masse are a type of bio-numeracy, and each brood is collectively a Sieve of Eratosthenes, sacrificing trillions to arrive at an agreed-upon prime number. In this, the cicada may be, as far as we know, the most horrific way to do math in the entire universe.

Being an embodied temporal calculation, the cicada invasion has forced upon us a new awareness of time itself. I have found your mother crying from this. She says every day now she thinks about the inherent question they pose: What will our lives be like, when the cicadas return?

Against our will the Bourbon Brood has scheduled something in our calendar, 17 years out, shifting the future from abstract to concrete. When the cicadas return, you will be turning 21. Your sister, 19. Myself, already 55. Your mother, 54. Your grandparents will, very possibly, all be dead. This phase of life will have finished. And to mark its end, the cicadas will crawl up through the dirt, triumphant in their true ownership, and the empty nest of our home will buzz again with these long-living, subterranean-dwelling, prime-calculating, calendar-setting, goddamn vampires.

Stubbornness

God, you’re stubborn. You are so stubborn. Stubborn about which water bottle to drink from, stubborn about doing all the fairground rides twice, stubborn about going up slides before going down them, pushing buttons on elevators, being the first to go upstairs, deciding what snack to eat, wearing long-sleeved shirts in summer, wanting to hold hands, wanting not to hold hands; in general, you’re stubborn about all events, and especially about what order they should happen in. You’re stubborn about doing things beyond your ability, only to get angry when you inevitably fail. You’re stubborn in wanting the laws of physics to work the way you personally think they should. You’re stubborn in how much you love, in how determined and fierce your attachment can be.

This is true of many young children, of course, but you seem an archetypal expression of it. Even your losing battles are rarely true losses. You propose some compromise where you can snatch, from the jaws of defeat, a sliver of a draw. Arguments with you are like trading rhetorical pieces in a chess match. While you can eventually accept wearing rain boots because it’s pouring out, that acceptance hinges on putting them on in the most inconvenient spot imaginable.

So when I get frustrated—and yes, I do get frustrated—I remind myself that “stubborn” is a synonym for “willful.” Whatever human will is, you possess it in spades. You want the world to be a certain way, and you’ll do everything in your power to make it so. Luckily, most of your designs are a kind of benevolent dictatorship. And at root, I believe your willfulness comes from loving the world so much, and wanting to, like all creatures vital with life force, act in it, and so bend it to your purposes.

What I don’t think is that this willfulness is because we, as parents, are so especially lenient. Because we’re not. No, your stubbornness has felt baked in from the beginning.

This might be impossible to explain to you now, in all its details, but in the future you’ll be ready to understand that I really do mean “the beginning.” As in the literal moment of conception. Or the moment before the moment, when you were still split into halves: egg and sperm. There is much prudery around the topic, as you’ll learn, and because of its secrecy people conceptualize the entire process as fundamentally simple, like this: Egg exists (fanning itself coquettishly). Sperm swims hard (muscular and sweaty). Sperm reaches egg. Penetrates and is enveloped. The end. But this is a radical simplification of the true biology, which, like all biology, is actually about selection.

Selection is omnipresent, occurring across scales and systems. For example, the elegance of your DNA is because so many variants of individuals were generated, and of these, only some small number proved fit in the environment (your ancestors). The rest were winnowed away by natural selection. So too, at another scale, your body’s immune system internally works via what’s called “clonal selection.” Many different immune cells with all sorts of configurations are generated at low numbers, waiting as a pool of variability in your bloodstream. In the presence of an invading pathogen, the few immune cells that match (bind to) the pathogen are selected to be cloned in vast numbers, creating an army. And, at another scale and in a different way, human conception works via selection too. Even though scientists understand less about how conception selection works (these remain mysterious and primal things), the evidence indicates the process is full of it.

First, from the perspective of the sperm, they are entered into a win-or-die race inside an acidic maze with three hundred million competitors. If the pH or mucus blockades don’t get them, the fallopian tubes are a labyrinth of currents stirred by cilia. It’s a mortal race in all ways, for the woman’s body has its own protectors: white blood cells, which register the sperm as foreign and other. Non-self. So they patrol and destroy them. Imagining this, I oscillate between the silly and the serious. I picture the white blood cells patrolling like stormtroopers, and meanwhile the sperm (wearing massive helmets) attempt to rush past them. But in reality, what is this like? Did that early half of you see, ahead, some pair of competing brothers getting horrifically eaten, and smartly went the other way? What does a sperm see, exactly? We know they can sense the environment, for of the hundreds of sperm who make it close enough to potentially fertilize the egg, all must enter into a kind of dance with it, responding to the egg’s guidance cues in the form of temperature and chemical gradients (the technical jargon is “sperm chemotaxis”). We know from experiments that eggs single out sperm non-randomly, attracting the ones they like most. But for what reasons, or based on what standards, we don’t know. Regardless of why, the egg zealously protects its choice. Once a particular sperm is allowed to penetrate its outer layer, the egg transforms into a literal battle station, blasting out zinc ions at any approaching runners-up to avoid double inseminations.

Then, on the other side, there’s selection too. For which egg? Women are born with about a million of what are called “follicles.” These follicles all grow candidate eggs, called “oocytes,” but, past puberty, only a single oocyte each month is chosen to be released by the winner and become the waiting egg. In this, the ovary itself is basically a combination of biobank and proving grounds. So the bank depletes over time. Menopause is, basically, when the supply has run out. But where do they all go? Most follicles die in an initial background winnowing, a first round of selection, wherein those not developing properly are destroyed. The majority perish there. Only the strongest and most functional go on to the next stage. Each month, around 20 of these follicles enter a tournament with their sisters to see which of them ovulates, and so releases the winning egg. This competition is enigmatic, and can only be described as a kind of hormonal growth war. The winner must mature faster, but also emit chemicals to suppress the others, starving them. The losers atrophy and die. No wonder it’s hard for siblings to always get along.

Things like this explain why, the older I get, the more I am attracted to one of the first philosophies, by Empedocles. All things are either Love or Strife. Or both.

From that ancient perspective, I can’t help but feel your stubbornness is why you’re here at all. That it’s an imprint left over, etched onto your cells. I suspect you won all those mortal races and competitions, succeeded through all that strife, simply because from the beginning, in some proto-way, you wanted to be here. Out of all that potentiality, willfulness made you a reality.

Can someone be so stubborn they create themselves?
