Biologists Announce There Absolutely Nothing We Can Learn From Clams


WOODS HOLE, MA—Saying they saw no conceivable reason to bother with the bivalve mollusks, biologists at the Woods Hole Oceanographic Institution announced Thursday that there was absolutely nothing to be learned from clams. “Our studies have found that while some of their shells look pretty cool, clams really don’t have anything to teach us,” said the organization’s chief scientist, Francis Dawkins, clarifying that it wasn’t simply the case that researchers had already learned everything they could from clams, but rather that there had never been anything to learn from them and never would be. “We certainly can’t teach them anything. It’s not like you can train them to run through a maze the way you would with mice. We’ve tried, and they pretty much just lie there. From what I’ve observed, they have a lot more in common with rocks than they do with us. They’re technically alive, I guess, if you want to call that living. They open and close sometimes, but, I mean, so does a wallet. If you’ve used a wallet, you know more or less all there is to know about clams. Pretty boring.” The finding follows a study conducted by marine biologists last summer that concluded clams don’t have much flavor, either, tasting pretty much the same as everything else on a fried seafood platter.

Monsters From the Deep



I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA ~ Rebecca R. Helm
***
"From the darkness of the deep, the mother rose slowly, her great body pulsing with effort, while the calf clung close to her side. The faint shimmer of the surface light caught on something twisting in her jaws—long pale arms, still trembling, a giant calamari dragged from the black abyss.

The calf pressed its head against the mother’s flank, curious, its small eye turning toward the strange, sprawling catch. Around them, the other whales gathered, a circle of giants, each click and creak of their voices carrying through the water like an ancient council.

The mother released a cloud of ink the squid had left behind, now dissipating in ghostly ribbons. She let the prey dangle for a moment before tearing a piece free with a practiced shake of her head. The calf tried to imitate, nudging the slack arms of the squid, but only managed to tangle its mouth in the trailing suckers. The adults rumbled with what could only be described as laughter.

High above, a shaft of sunlight pierced the water, illuminating the drifting arms of the squid like banners in the deep. The feast had begun, but it was also a lesson—the calf’s first glimpse of the abyss’s hidden monsters, and of the power its mother carried up from the dark world below."

Plastic-Eating Fungus

A fungus from the Amazon rainforest can break down polyurethane plastic without oxygen. It's the first organism discovered with this capability, and it can survive using plastic as its only food source.

Most plastic waste ends up deep in landfills where oxygen doesn't reach, precisely where this fungus thrives. Polyurethane persists for centuries in these environments. It's everywhere: mattresses, insulation foam, shoe soles, adhesives, car parts. Annual global plastic production exceeds 400 million tons. Less than 10% gets recycled.

Pestalotiopsis microspora was discovered in 2011 in Ecuador's Yasuní National Forest, isolated from plant stems. The endophytic fungus lives inside plant tissues without harming its host. Laboratory testing revealed its remarkable ability: it degrades plastic equally well with or without oxygen present.

The fungus secretes an enzyme that breaks apart the chemical bonds holding polyurethane together. In laboratory tests, concentrated enzyme extracts can completely break down polyurethane polymer in under an hour. The fungus also produces a second enzyme that degrades PET plastic, splitting it into simpler compounds the fungus then consumes as food.

What makes this significant? Other plastic-degrading organisms need oxygen to function. When tested without oxygen, fungi like Lasiodiplodia and Pleosporales slowed down or stopped working. P. microspora maintained the same performance. This ability to work without oxygen directly addresses the actual problem—plastic buried in oxygen-depleted landfill depths.

The enzyme production is adaptive. When the fungus grows in a basic environment with only plastic available, it ramps up enzyme output. These enzymes spread through the surrounding material, breaking down plastic well beyond where the fungus itself is growing. The enzyme breakdown converts long-lasting polymer into simple compounds the fungus uses as food.

This fungus offers a biological solution that works precisely where the problem exists, in oxygen-depleted landfills where an ever-increasing amount our plastic waste collects.

AI Overview:
Q. How long does it take Pestalotiopsis microspora to eat plastic?

Pestalotiopsis microspora can degrade plastic in a matter of weeks to months, with experiments showing significant degradation in as little as two weeks and over 60% breakdown in six weeks under ideal conditions. The specific timeframe varies, with some sources noting a few months for complete digestion in certain projects.

Ask Not Why You Would Work in Biology, But Rather: Why Wouldn't You?

There’s a lot of essays that are implicitly centered around convincing people to work in biology. One consistent theme amongst them is that they all focus on how irresistibly interesting the whole subject is. Isn’t it fascinating that our mitochondria are potentially an endosymbiotic phenomenon that occurred millions of years ago? Isn’t it fascinating that the regulation of your genome can change throughout your life? Isn’t it fascinating that slime molds can solve mazes without neurons? Come and learn more about this strange and curious field! (...)

But I’d like to offer a different take on the matter. Yes, biology is very interesting, yes, biology is very hard to do well. Yet, it remains the only field that could do something of the utmost importance: prevent a urinary catheter from being shunted inside you in the upcoming future.

Being catheterized is not a big deal. It happens to literally tens of millions of people every single year [ed. Really? Just checked and it's true, at least for millions.]. There is nothing even mildly unique about the whole experience. And, you know, it may be some matter of privilege that you ever feel a catheter inside of you; the financially marginalized will simply soil themselves or die a very painful death from sepsis.

But when you are catheterized for the first time—since, make no mistake, there is a very high chance you will be if you hope to die of old age—you’ll almost certainly feel a sense of intense wrongness that it happens at all. The whole procedure is a few moments of blunt violence, invasiveness, that feels completely out of place in an age where we can edit genomes and send probes beyond the solar system. There may be times where you’ll be able to protect yourself from the vile mixture of pain and discomfort via general anesthesia, but a fairly high number of people undergo (repeated!) catheterization awake and aware, often gathering a slew of infections along the way. This is made far worse by the fact that the most likely time you are catheterized will be during your twilight years, when your brain has turned to soup and you’ve forgotten who your parents are and who you are and what this painful tube is doing in your urethra. If you aren’t aware of how urinary catheters work, there is a deflated balloon at the end of it, blown up once the tube is inside you. This balloon keeps the whole system uncomfortably stuck inside your bladder. So, you can fill in the details on how much violence a brain-damaged person can do to themselves in a position like this by simply yanking out the foreign material.

Optimizing for not having a urinary catheter being placed into you is quite a lofty goal. Are there any alternatives on the table? Not practical ones. Diapers don’t work if the entire bladder itself is dysfunctional, suprapubic tubes require making a hole into the bladder (and can also be torn out), and nerve stimulation devices require expensive, invasive surgery. And none of them will be relied upon for routine cases, where catheterization is the fastest, most reliable solution that exists. You won’t get the gentle alternatives because you won’t be in a position to ask for them. You’ll be post-operative, or delirious, or comatose, or simply too old and confused to advocate for something better.

This is an uncomfortable subject to discuss. But I think it’s worth level-setting with one another. Urinary catheterization is but one of the dozens of little procedures that both contributes to the nauseating amount of ambient human suffering that repeats over and over and over again across the entire medical system and is reasonably common enough that it will likely be inflicted upon you one day. And if catheterization doesn’t seem so bad, there are a range of other awful things that, statistically speaking, a reader has a decent chance of undergoing at some point: feeding tubes, pap smears, mechanical ventilation, and repeated colonoscopies are all candidates.

Moreover, keep in mind that all these are simply the solutions to help prevent something far more grotesque and painful from occurring! Worse things exist—cancer, Alzheimer’s, Crohn’s—but those have been talked about to death and feel a great deal more abstract than the relatively routine, but barbaric, medical procedures that occur millions of times per year.

How could this not be your life goal to work on? To reduce how awful maladies, and the awful solutions to those maladies, are? What else is there really? Better prediction markets? What are we talking about?

To be fair, most people go through their first few decades of life not completely cognizant how terrible modern medicine can be. But at some point you surely have to understand that you have been, thus far, lucky enough to have spent your entire life on the good side of medicine. In a very nice room, one in which every disease, condition, or malady had a very smart clinician on staff to immediately administer the cure. But one day, you’ll one day be shown glimpses of a far worse room, the bad side of medicine, ushered into an area of healthcare where nobody actually understands what is going on. (...)

I appreciate that many fields also demand this level of obedience to the ‘cause’, the same installation of ‘this is the only thing that matters!’. The energy, climate change, and artificial-intelligence sectors have similar do-or-die mission statements. But you know the main difference between those fields and biology?

In every other game, you can at least pretend the losers are going to be someone else, somewhere else in the world, happening to some poor schmuck who didn’t have your money or your foresight or your connections to do the Obviously Correct Thing. Instead, people hope to be a winner. A robot in my house to do my laundry, a plane that gets me from San Francisco to New York City in only an hour, an infinite movie generator so I can turn all my inner thoughts into reality. Wow! Capital-A Abundance beyond my wildest dreams! This is all well and good, but the unfortunate reality of the situation is that you will be a loser, an explicit loser, guaranteed to be a loser, in one specific game: biology. You will not escape being the butt of the joke here, because it will be you that betrays you, not the you who is reading this essay, but you, the you that cannot think, the you that has been shoddily shaped by the last several eons of evolution. Yes, others will also have their time underneath this harsh spotlight, but you will see your day in it too. (...)

Yes, things outside of biology are important too. Optimized supply chains matter, good marketing matters, and accurate securities risk assessments matter. Industries work together in weird ways. The people working on better short-form video and payroll startups and FAANGs are part of an economic engine that generates the immense taxable wealth required to fund the NIH grants. I know that the world runs on invisible glue.

Still, I can’t help but think that people’s priorities are enormously out of touch with what will actually matter most to their future selves. It feels as if people seem to have this mental model where medical progress simply happens. Like there’s some natural law of the universe that says “treatments improve by X% per year” and we’re all just passengers with a dumb grin on this predetermined trajectory. They see headlines about better FDA guidelines or CRISPR or immunotherapy or AI-accelerated protein folding and think, “Great, the authorities got it covered. By the time I need it, they’ll have figured it out.”. But that’s not how any of this works! Nobody has it covered! Medical progress happens because specific people chose to work on specific problems instead of doing something else with their finite time on Earth.

Do Coconuts Go With Oysters? For Saving the Delaware Shore, Yes.

For the past 50 years, Gary Berti has watched as a stretch of Delaware’s coastline slowly disappeared. Rising tides stripped the shoreline, leaving behind mud and a few tree stumps.

“Year after year, it gradually went from wild to deteriorated,” said Mr. Berti, whose parents moved to Angola by the Bay, a private community in Lewes, Del., in 1977, where he now lives with his wife, Debbie.

But in 2023, an extensive restoration effort converted a half-mile of shoreline from barren to verdant. A perimeter of logs and rolls of coconut husk held new sand in place. Lush beds of spartina, commonly known as cordgrass, grew, inviting wading birds and blue crabs.

Together, these elements have created a living shoreline, a nature-based way of stabilizing the coast, to absorb energy from the waves and protect the land from washing away. 

Mr. Berti had never seen the waterfront like this before. “The change has just been spectacular,” he said.

Before
After

The practice of using natural materials to prevent erosion has been around for decades. But as sea levels rise and ever-intensifying storms pound coastlines, more places are building them.

The U.S. government counts at least 150 living shorelines nationwide, with East Coast states like Maryland, South Carolina and Florida remediating thousands of feet of tidal areas. Thanks to the efforts of the Delaware Living Shorelines Committee, a state-supported working group, Delaware has led the charge for years. (...)

“The living component is key,” said Alison Rogerson, an environmental scientist for the state’s natural resources department and chair of the living shoreline committee.

The natural materials, she said, provide a permeable buffer. As waves pass through, they leave the mud and sand they were carrying on the side of the barrier closer to the shore. This sediment builds up over time, creating a stable surface for plants. As the plants grow, their roots reinforce the barrier by holding everything in place. The goal is not necessarily return the land to how it was before, but to create new, stronger habitat.

More traditional rigid structures, like concrete sea walls, steel bulkheads and piles of stone known as riprap, can provide instant protection but inevitably get weaker over time. Bulkheads can also backfire by eroding at the base or trapping floodwaters from storms. And because hardened structures are designed to deflect energy, not absorb it, they can actually worsen erosion in nearby areas.

Though living shorelines need initial care while they start to grow, scientists have found they can outperform rigid structures in storms and can repair themselves naturally. And as sea levels rise, living shorelines naturally inch inland with the coastline, providing continuous protection, whereas sea walls have to be rebuilt.

When the engineers leave after creating a gray rigid structure, like a sea wall, “that’s the strongest that structure is ever going to be, and at some point, it will fail,” said David Burdick, an associate professor of coastal ecology at the University of New Hampshire. “When we install living shorelines, it’s the weakest it’s going to be. And it will get stronger over time.”

And just as coastal areas come in all shapes and sizes, so do living shorelines. In other places that the committee has supported projects, like Angola by the Bay and the Delaware Botanical Garden, brackish water meant that oysters wouldn’t grow. Instead, the private community opted for large timber logs while the botanical garden built a unique crisscross fence from dead tree branches found on site. (...)

Sometimes, an area’s waves and wind are too powerful for a living shoreline to survive on its own, Mr. Janiec said. In these situations, a hybrid approach that combines hard structures can create a protected zone for plants and oysters to grow. And these don’t need to be traditional sea walls or riprap. Scientists can also use concrete reef structures and oyster castles to break up waves while allowing wildlife to thrive.

Gregg Moore, an associate professor of coastal restoration at the University of New Hampshire, said homeowners often choose rigid structures because they don’t act on erosion until the situation is urgent. When it comes to a person’s home, “you can’t blame somebody for wanting to put whatever they think is the fastest, most permanent solution possible,” he said. (...)

“Living shorelines are easier than people think, but they take a little time,” Mrs. Allread said. “You have to trust the process. Nature can do its own thing if you let it.”

[ed. Streambank and coastal restoration/rehabilitation using bioengineering techniques has been standard practice in Alaska for decades (in fact, my former gf wrote the book on it - literally). I myself received a grant to rehabilitate 12 state park public use sites on the Kenai River (see here and here) that were heavily damaged and eroding from constant foot traffic and boat wakes. Won a National Coastal America Award for innovation. As noted here, most people want a quick fix, but this is a better, long-term solution.]

Jane Goodall Chronicled the Social Lives of Chimps, Dies at 91

Jane Goodall, one of the world’s most revered conservationists, who earned scientific stature and global celebrity by chronicling the distinctive behavior of wild chimpanzees in East Africa — primates that made and used tools, ate meat, held rain dances and engaged in organized warfare — died on Wednesday in Los Angeles. She was 91.

Her death, while on a speaking tour, was confirmed by the Jane Goodall Institute, whose U.S. headquarters are in Washington, D.C.

The British-born Dr. Goodall was 29 in the summer of 1963 when the National Geographic Society, which was financially supporting her field studies in the Gombe Stream Chimpanzee Reserve in what is now Tanzania, published her 7,500-word, 37-page account of the lives of Flo, David Greybeard, Fifi and other members of the troop of primates she had observed.

The article, with photographs by Hugo van Lawick, a Dutch wildlife photographer whom she later married, also described her struggles to overcome disease, predators and frustration as she tried to get close to the chimps, working from a primitive research station along the eastern shore of Lake Tanganyika

On the scientific merits alone, Dr. Goodall’s discoveries about how wild chimpanzees raised their young, established leadership, socialized and communicated broke new ground and attracted immense attention and respect among researchers. Stephen Jay Gould, the evolutionary biologist and science historian, said her work with chimpanzees “represents one of the Western world’s great scientific achievements.”

On learning of Dr. Goodall’s documented evidence that humans were not the only creatures capable of making and using tools, Louis Leakey, the paleoanthropologist and Dr. Goodall’s mentor, famously remarked, “Now we must redefine ‘tool,’ redefine ‘man,’ or accept chimpanzees as humans.”

Long before focus groups, message discipline and communications plans became crucial tools in advancing high-profile careers and alerting the world to significant discoveries in and outside of science, Dr. Goodall understood the benefits of being the principal narrator and star of her own story of discovery.In articles and books, her lucid prose carried vivid descriptions, some lighthearted, of the numerous perils she encountered in the African rainforest — malaria, leopards, crocodiles, spitting cobras and deadly giant centipedes, to name a few. Her writing gained its widest attention in three more long articles in National Geographic in the 1960s and ’70s and in three well-received books, “My Friends, the Wild Chimpanzees” (1967), “In the Shadow of Man” (1971) and “Through a Window” (1990).

Dr. Goodall’s willingness to challenge scientific convention and shape the details of her arduous research into a riveting adventure narrative about two primary subjects — the chimps and herself — turned her into a household name, in no small part thanks to the power of television.

Dr. Goodall’s gentle, knowledgeable demeanor and telegenic presence — set against the beautiful yet dangerous Gombe preserve and its playful and unpredictable primates — proved irresistible to the networks. In December 1965, CBS News broadcast a documentary of her work in prime time, the first in a long string of nationally and internationally televised special reports about the chimpanzees of Gombe and the courageous woman steadfastly chronicling what she called their “rich emotional life.” (...)

And in becoming one of the most famous scientists of the 20th century, Dr. Goodall opened the door for more women in her largely male field as well as across all of science. Women — including Dian Fossey, Biruté Galdikas, Cheryl Knott and Penny Patterson — came to dominate the field of primate behavior research.

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.
