George Musser in Nautilus:
Michael Levin, a developmental biologist at Tufts University, has a knack for taking an unassuming organism and showing it’s capable of the darnedest things. He and his team once extracted skin cells from a frog embryo and cultivated them on their own. With no other cell types around, they were not “bullied,” as he put it, into forming skin tissue. Instead, they reassembled into a new organism of sorts, a “xenobot,” a coinage based on the Latin name of the frog species, Xenopus laevis. It zipped around like a paramecium in pond water. Sometimes it swept up loose skin cells and piled them until they formed their own xenobot—a type of self-replication. For Levin, it demonstrated how all living things have latent abilities. Having evolved to do one thing, they might do something completely different under the right circumstances.
Not long ago I met Levin at a workshop on science, technology, and Buddhism in Kathmandu. He hates flying but said this event was worth it. Even without the backdrop of the Himalayas, his scientific talk was one of the most captivating I’ve ever heard. Every slide introduced some bizarre new experiment. Butterflies retain memories from when they were caterpillars, even though their brains turned to mush in the chrysalis. Cut off the head and tail of a planarian, or flatworm, and it can grow two new heads; if you amputate again, the worm will regrow both heads.

When the notable figures of our day pass away, they wind up on our screens, short clips documenting their achievements, talking heads discussing their influence. The quiet lives, though, pass on soundlessly in the background. And yet those are the lives in our skin, guiding us from breakfast to bed. They’re the lives that have made us, that keep the world turning.
We have just experienced the hottest day ever recorded on Earth – for the second day in a row. The average global air temperature recorded 2 metres above Earth’s surface hit 17.18°C (62.92°F) on 4 July,
In the mid-1920s, the mood in the United States was buoyant. After years of surging economic growth, fuelled by expansion in the automobile industry and speculation in financial markets, the United States had the lowest debt of any large industrial nation. The future looked just as rosy. A 1926 article in The Wall Street Journal noted how “American wealth has doubled in the past dozen years”, delivering “a rate of progress that has never been known in Europe”.
Among the literary genres, biography appears to be thriving. Perhaps it satisfies some element of life writing we also get from fiction, adding a dose of gossip and the illusion that we can actually know the truth of other people’s lives. There is always more than one way to tell a story. Some good recent biographies have been thematic or experimental: Katherine Rundell on John Donne, Frances Wilson on D. H. Lawrence, Andrew S. Curran on Diderot, Clare Carlisle on Kierkegaard. We have authoritative doorstoppers from Langdon Hammer on James Merrill to Heather Clark’s numbingly detailed book on Sylvia Plath. And we find a happy medium-sized biography in Mark Eisner’s on Neruda or Ann-Marie Priest’s on the great Australian poet Gwen Harwood. Among the best of these, Brigitta Olubas’ Shirley Hazzard: A Writing Life is not overstuffed or particularly arcane in structure, not weighted down with newly discovered scandal, but lucidly and even gracefully organized, guided by a compelling thesis.
IN A 2013 AFTERWORD
For the first thirty years of my life, I lived within a one-mile radius of Willesden Green Tube Station. It’s true I went to college—I even moved to East London for a bit—but such interludes were brief. I soon returned to my little corner of North West London. Then suddenly, quite abruptly, I left not just the city but England itself. First for Rome, then Boston, and then my beloved New York, where I stayed ten years. When friends asked why I’d left the country, I’d sometimes answer with a joke: Because I don’t want to write a historical novel. Perhaps it was an in-joke: only other English novelists really understood what I meant by it. And there were other, more obvious reasons. My English father had died. My Jamaican mother was pursuing a romance in Ghana. I myself had married an Irish poet who liked travel and adventure and had left the island of his birth at the age of eighteen. My ties to England seemed to be evaporating. I would not say I was entirely tired of London. No, I was not yet—in

Anything I could ever know about Caravaggio derives from what Roberto Longhi had to say about him. Yes, Caravaggio was a great inventor, and thus a great realist. But what did Caravaggio invent? In answering this rhetorical question, I cannot help but stick to Longhi’s example. First, Caravaggio invented a new world that, to invoke the language of cinematography, one might call profilmic. By this I mean everything that appears in front of the camera. Caravaggio invented an entire world to place in front of his studio’s easel: new kinds of people (in both a social and characterological sense), new kinds of objects, and new kinds of landscapes. Second: Caravaggio invented a new kind of light. He replaced the universal, platonic light of the Renaissance with a quotidian and dramatic one. Caravaggio invented both this new kind of light and new kinds of people and things because he had seen them in reality. He realized that there were individuals around him who had never appeared in the great altarpieces and frescoes, individuals who had been marginalized by the cultural ideology of the previous two centuries. And there were hours of the day—transient, yet unequivocal in their lighting—which had never been reproduced, and which were pushed so far from habit and use that they had become scandalous, and therefore repressed. So repressed, in fact, that painters (and people in general) probably didn’t see them at all until Caravaggio.
‘We see pictures in time and place … They are fragments of our lives, moments of existence that may be as unremarkable as rain or as startling as a clap of thunder,’ Cumming writes. A love of Dutch art and a passion for looking at pictures were bequeathed to Cumming by her artist parents. She wrote about her mother’s fragmented, mysterious early life in On Chapel Sands (2019). In Thunderclap it is Laura’s father, James Cumming, who takes centre stage, and like On Chapel Sands the book is infused with love – of parents, childhood, pictures and words. It is at once deeply personal and inclusive, because it is about the shared experience of looking at pictures and the shared desire to know and understand what these ‘moments of existence’ mean. I liked reading Thunderclap so much that I immediately reread On Chapel Sands. Together, these books are a remarkable experiment in form as well as a richly satisfying extended meditation on art, life and death.

The discovery, announced today, shows that extra-large ripples in space-time are constantly squashing and changing the shape of space. These gravitational waves are cousins to the echoes from black hole collisions first picked up by the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment in 2015. But whereas LIGO’s waves might vibrate a few hundred times a second, it might take years or decades for a single one of these gravitational waves to pass by at the speed of light.
