Krøyer’s deep-sea anglerfish, Ceratias holboelli, does not spawn, copulate, or do anything a fish would ordinarily do to mate. Instead, the male—just a few inches long—clasps onto the comparatively gigantic female’s body and never lets go. Slowly, his body morphs into hers, his cells becoming hers, including his testicles, which are used to make offspring. As he vanishes, two individuals become one—taking the concept of monogamy to a new level.
The sub-order of deep-sea anglerfish, composed of nearly 170 known species, arguably displays the most dramatic mating habits in the animal kingdom. In some species, males only temporarily attach to females and then part ways. In others, such as C. holboelli, males permanently “fuse” with females, or females absorb multiple males—in some cases up to eight at a time.
Among the many mysteries surrounding these deep-sea rendezvous—they were only captured on camera for the first time in 2018—is an immunological one. In virtually all other adult vertebrates, introducing tissue from one individual into another would provoke a powerful immune response attacking the foreign cells. Why don’t the female anglerfish, immunologically speaking, reject these parasitic males?
A new genomic analysis of 13 anglerfish species published today (July 30) in Science provides some clues. The genomes of species that temporarily or permanently fuse with their mates have undergone radical alterations of key genes that underpin adaptive immunity—a branch of the immune system responsible for the rejection of foreign tissue—making some of them the first known instances of vertebrates that effectively lack an adaptive immune system. Over the course of evolution, changes in genes involved in antibody production and cytotoxic T cell responses may have paved the way for the animals’ strange reproductive habits, while for scientists it raises questions about how the fish defend themselves against pathogens in the deep sea.

We are living, in case you haven’t noticed, in a world full of bullshit. It’s hard to say whether the amount is truly increasing, but it seems that everywhere you look someone is trying to convince you of something, regardless of whether that something is actually true. Where is this bullshit coming from, how is it disseminated, and what can we do about it? Carl Bergstrom studies information in the context of biology, which has led him to investigate the flow of information and disinformation in social networks, especially the use of data in misleading ways. In the time of Covid-19 he has become on of the best Twitter feeds for reliable information, and we discuss how the pandemic has been a bounteous new source of bullshit.
The peculiarity of hindsight is that it depends on the point from which you look back at Pakistan’s and India’s trajectories. In the early 1970s and till the late 1990s, as Pakistan itself broke up into two and generals and mullahs controlled its politics, India could afford to be smug. In 1992, the destruction of the Babri Masjid changed that, and the consequences of India’s 2014 election are there for us to see. Some Pakistanis may feel triumphant, but the virtue of Pakistani lawyer Yasser Latif Hamdani’s new biography, Jinnah: A Life, is that it takes a sober tone.
Bishop published only about a hundred poems during her lifetime, but won the most prestigious prizes for American literature: the Pulitzer in 1956 and the National Book Award in 1970. Brilliant, quirky critic Randall Jarrell described her poems as “honest, modest, minutely observant, masterly. . . . The poems are like Vuillard or even, sometimes, Vermeer.” Bishop was overwhelmed: “It has always been one of my dreams that someday someone would think of Vermeer, without my saying it first”—adding cheerfully, “So now I think I can die in a fairly peaceful frame of mind any old time.” Her life was tumultuous and tragic, but also filled with love and lust. Bishop’s father died when she was only a few months old, a loss her mother, mentally unstable Gertrude Bulmer, never overcame. Her loving, but simple, maternal grandparents raised Bishop in Great Village, a hamlet in Nova Scotia, Canada, during her infancy, while Bulmer was locked up in an insane asylum for long periods. When Bishop was five years old, Bulmer was put away forever, mostly in solitary confinement. She would never see her mother again. Soon after, suddenly, her father’s parents took her to Worcester, Massachusetts, and Bishop ended up in a world that was less austere, but much colder and more distant. Lonely and alone, she was plagued by terrible asthma and eczema; Travisano convincingly argues that these had psychosomatic origins.
In making these claims about academic writing, I am thinking in the first instance of my own corner of academia—philosophy—though I suspect that my points generalize, at least over the academic humanities. To offer up one anecdote: in spring 2019 I was teaching Joyce’s Portrait of the Artist as a Young Man; since I don’t usually teach literature, I thought I should check out recent secondary literature on Joyce. What I found was abstruse and hypercomplex, laden with terminology and indirect. I didn’t feel I was learning anything I could use to make the meaning of the novel more accessible to myself or to my students. I am willing to take some of the blame here: I am sure I could have gotten something out of those pieces if I had been willing to put more effort into reading them. Still, I do not lack the intellectual competence required to understand analyses of Joyce; I feel all of those writers could have done more to write for me.
Back in the ’30s — the 1130s — the Welsh cleric Geoffrey of Monmouth created the impression that Stonehenge was built as a memorial to a bunch of British nobles slain by the Saxons. In his “
Over the past two years a striking change has taken place in the boardrooms of greenhouse-gas producers: a growing number of large companies have announced commitments to achieve “net zero” emissions by 2050. These include the oil majors BP, Shell, and Total, the mining giant Rio Tinto, and the electricity supplier Southern Company. While such commitments are often described as “voluntary”—not mandated by government regulation—they were often adopted begrudgingly by executives and boards acquiescing to demands made by a coordinated group of their largest shareholders.
At the heart of every white dwarf star—the dense stellar object that remains after a star has burned away its fuel reserve of gases as it nears the end of its life cycle—lies a quantum conundrum: as white dwarfs add mass, they shrink in size, until they become so small and tightly compacted that they cannot sustain themselves, collapsing into a neutron star.
Am I being reductive? All of narrative fiction, I’ve suggested, can be sorted into four grand categories. Each presents a rich world of feeling in which any number of stories can be told and positions established, but always in relation to, or rather, driven by, a distinct cluster of values and consequent emotions. My claim is that it really is worth being aware which of these worlds we are being drawn into. We read better. We know where we are. And what the dangers are.
As we head into a tumultuous US election season, it is worth remembering that political parties can get trapped in partisan frameworks that cater to the loudest sections of their base, but which prevent them from appealing to a wider range of voters. Ideological litmus tests not only narrow appeal, but they cause politicians to pander, to disregard evidence, and to reject compromise in favor of rhetorical stridency. Social conservatives’ endlessly sputtering crusade over pornography is unusual in that it brings them into alliance with many radical feminists on the Left. Nevertheless, of the two main parties, it is the moral majoritarians in the Republican Party who have most frequently attempted to generate political capital by inveighing against pornography. This movement’s foundational moment was President Reagan’s Meese commission established to investigate the potential harms caused by pornography. The Meese Report, however, badly over-reached—even those who worry about the effects of pornography acknowledge it made
