Christian Sonne in Nature:
The Arctic is under stress, that much is known. Between 1979 and 2021, the region warmed four times faster than the global average, with effects — as yet poorly understood — on its ecology and ability to store carbon, on global sea levels and on wider ocean-circulation and weather patterns.
Add in the effects of biodiversity loss and pollution, and people often refer to a triple planetary crisis. I think we should actually be talking about a quadruple crisis. Since starting research in the Arctic in 1997, I have spent nearly all of my summers there, monitoring changes in pollution levels, habitats and food webs using a ‘One Health’ approach that integrates effects on wildlife, humans and ecosystems. And it’s becoming clear that, as the Arctic warms, its environment degrades and human activities increase, new health threats are emerging. In particular, the Arctic is likely to become a hotbed for zoonotic diseases that spill over into humans from other animals. That threat was brought home to all of us by the COVID-19 pandemic. We need to take seriously the possibility that the next pandemic could come from the north.

In the spring of 1961, Gerhard Richter, a young East German artist noted mainly for his portraits and socialist wall paintings, slipped through the last chink in the Iron Curtain—West Berlin—and fled to the Federal Republic of Germany. A few weeks later, he justified this move in a letter to his former teacher at the Dresden Academy of Fine Arts: “My reasons are mainly professional. The whole cultural ‘climate’ of the West can offer me more, in that it corresponds better and more coherently with my way of being and working than that of the East.”
My first visceral memories of the regime in Iran were formed before I was born. My mother had been in the notorious Evin prison in the 1980s, when hanged bodies were lined up along the entrance path so that prisoners knew what to expect. Although naturally apolitical, my mother was seen with a dissident. She narrowly escaped lynching, only because the dissident learned of my mother’s arrest and turned herself in.

Though bears loom large in our collective imagination, their flesh-and-blood counterparts are increasingly losing ground. Eight Bears, the debut of environmental journalist Gloria Dickie, draws on visits to key hotspots where Earth’s remaining bear species come into conflict with humans. By interviewing scores of people, both conservationists and those suffering at the paws of these large predators, this nuanced and thought-provoking reportage asks whether humans and bears can coexist.

SEVENTY YEARS AGO, Ray Bradbury, then 33 years old—the author of The Martian Chronicles (1950), The Illustrated Man (1951), and Fahrenheit 451 (1953)—stood in front of a mirror in a London hotel room and declared, “I … am Herman Melville!” It was a last-ditch effort to channel the great American writer of Moby-Dick (1851). For Bradbury, it was either that or accept complete failure.

Depression doesn’t mean you’re always feeling low. Sure, most times it’s hard to crawl out of bed or get motivated. Once in a while, however, you feel a spark of your old self—only to get sucked back into an emotional black hole. There’s a reason for this variability. Depression changes brain connections, even when the person is feeling okay at the moment. Scientists have long tried to map these alternate networks. But traditional brain mapping technologies average multiple brains, which doesn’t capture individual brain changes.
In 2009, A US security intelligence operative stationed in Iraq began to notice some gaps in the American government’s “surgical precision” drone strategy. “I was trained to be an all-source analyst,” writes Chelsea Manning in her memoir, README.TXT (2022). “I’m used to collecting the full context and getting—and sharing—as much detail as possible.”
In the eighth-century CE the Abbasids undertook to collect the wisdom of the world in their new capital at Baghdad. This project started with the second Abbasid caliph, al-Mansur (“the Conqueror,” r. 754–74), who commissioned Arabic translations of important scientific texts from Persian, Sanskrit, Greek, and Syriac (a late form of Aramaic), and came into its own under al-Ma’mun (“the Trusted One,” r. 813–33).
