Eve Livingston sensitively draws us into the worlds of two women who share a similar past: abusive partners who committed suicide. Through powerful scene‑setting, we’re there when each woman hears the news, and we feel the complex emotions these deaths provoke. This is a difficult, complicated subject—not often tackled. Livingston bravely shines a light on how, in these particular circumstances, suicide can bring both grief and relief.

Things started as they so often do: he was older, professionally successful in a similar field to Siri’s, and there was something “magnetic” about him. There was also, she came to realise, a darkness beneath the surface. A tragic bereavement in his past had left him struggling with his mental health, something which immediately evoked sympathy in Siri and made him seem a deeper and more sensitive person, qualities she was drawn to. At the beginning of their relationship, he would often turn up uninvited to her home or events she was attending, or bombard her with messages — behaviour she now views as stalking, but found flattering in those hazy early days of a new relationship.

Krill, writes Gordon Peake, are “the least zeitgeisty creatures imaginable”: small, shrimp-like crustaceans whose total population numbers in the hundreds of trillions. Until recently, krill has mostly served as a snack for whales. Now, however, krill is “the latest iteration of capitalism on the frozen frontier,” a health supplement whose market is valued at roughly a billion dollars. Peake spends weeks aboard the Allankay with a crew of vegan activists devoted to ending the krill trade. His dispatch is a brisk history of extractive capitalism in the Antarctic, a fascinating study of an utterly uncool creature, and an uproarious account of a reluctant sailor earning his sea legs. Take the journey with him.

I contemplated the fillets of pink salmon defrosting on my kitchen counter, not too far from the shelf where I keep my supplements, including krill oil, part of my long-established daily routine of taking elixirs with vague but impressive claims about “improved heart health” and “enhanced brain function.” Labels depicting regal seabirds and majestic trawlers and a barmy sense that the more expensive the supplement, the more potent it must be also guided my “decision-making.” I told Hammarstedt I was the sort of fellow who enabled such an industry to exist. He responded with an offer: I should go down to Antarctica to see the krill business for myself.

“We have fallen into habits that are steadily deskilling the human body,” writes Melanie Challenger. “This is a strange turn of events for an animal whose success comes mostly from the extraordinary ability to learn through experience.” For Aeon, Challenger explores how modern technologies, from GPS to AI, are eroding our body’s physical skills by replacing the embodied experiences through which we learn.

After all, the brain is itself a physical organ, continually shaped by what the body does and encounters. Once we decide that the mind is the real human and the rest of the body only hardware, it becomes easier to disregard the physical work, including the neurocognitive work of a biological brain, through which we move, find our way, put thoughts into words, and recognise our own needs. A machine may do some of that work faster, but each act it takes over is one that the body no longer performs and that the body, including the brain, no longer learns through. The irony is that a project motivated by the desire to overcome bodily fragility is helping to produce more fragile bodies.

By studying fire scars in ancient wood, many scientists have become convinced that Indigenous people transformed North America long before European colonizers arrived. M.R. O’Connor spends time with dendrochronologists, who study tree rings, and other experts to understand what they’re learning:

Anthropologist Omer Stewart, who began documenting Native American burning practices in the nineteen-thirties . . . found that Indigenous communities burned prairies to attract bison to fresh grass and to maintain oak “orchards” where food could be gathered. He became convinced that Native Americans had reshaped the geography, and in some cases the climate, of North American ecosystems. Their impact “was profound, in terms of the amount of land converted to agriculture, the species they hunted and fished, and most particularluthe way they shaped their world through the use of fire,” the naturalist Scott Weidensaul wrote, in his 2012 book The First Frontier. Weidensaul argued that early America “was fruitful beyond modern recognition, it was riotous in its natural wealth, but it was not wilderness.” The dendrochronologist Evan Larson, at the University of Wisconsin-Platteville, made a similar claim: settlers encountered rich landscapes because Native Americans were tending them. “Whenever you’re talking about fire, you’re engaging with a central narrative around this untamed frontier and wilderness,” Larson told me. “In fact, that’s never been true. The early success of pioneers was already benefitting from the labor of somebody else.”
