Roughly half of Earth’s ice-free land remains without significant human influence, according to a study from a team of international researchers led by the National Geographic Society and the University of California, Davis. The study, published in the journal Global Change Biology, compared four recent global maps of the conversion of natural lands to anthropogenic land uses to reach its conclusions. The more impacted half of Earth’s lands includes cities, croplands, and places intensively ranched or mined. “The encouraging takeaway from this study is that if we act quickly and decisively, there is a slim window in which we can still conserve roughly half of Earth’s land in a relatively intact state,” said lead author Jason Riggio, a postdoctoral scholar at the UC Davis Museum of Wildlife and Fish Biology.
…Approximately 15 percent of the Earth’s land surface and 10 percent of the oceans are currently protected in some form. However, led by organizations including Nature Needs Half and the Half-Earth Project, there have been bold global calls for governments to commit to protecting 30 percent of the land and water by 2030 and 50 percent by 2050. Intact natural lands across the globe can help purify air and water, recycle nutrients, enhance soil fertility and retention, pollinate plants, and break down waste products. The value of maintaining these vital ecosystem services to the human economy has been placed in the trillions of U.S. dollars annually.

You may have noticed that there are a lot of writers writing a lot about the coronavirus. As every day passes, I want to read these pieces less and less. I don’t care about the subtleties of your daily experience under lockdown, Sensitive Writer Person. I don’t care about your analysis of how everything is going to change or about how everything is actually not really going to change, Journalist. I am indifferent as to your recommendations, Pundit. I give not a crap about your brilliant reading of Camus in light of COVID-19, Essayist. I’m in a boycott, a deep boycott. I will read nothing about coronavirus until 2030; this is my current and most solemn pledge.
When representation theory emerged in the late 19th century, many mathematicians questioned its worth. In 1897, the English mathematician William Burnside wrote that he doubted that this unorthodox perspective would yield any new results at all.
Tear gas rounds describe a graceful arc as they drop down out of the blue sky, trailing feathery tails of smoke like streamers. The shells hit the road with a ping, and sparks fly as they skip gaily along the asphalt. As they roll to a stop, the shells hiss like an angry snake, dense smoke pouring out of the top of the small aluminum canister, and soon the street is enveloped in clouds.

It was only in the second volume of Warburg’s Gesammelte Schriften (Collected Writings), published in 2000, that the glass negatives created in 1929 were used to publish fragmentary pictorial evidence of the “Bilderatlas Mnemosyne.” Editors Martin Warnke and Claudia Brink produced black-and-white images from the negatives, printing them at a reduced size that tended to obscure their details. They also left off additional commentary, given the lack of extant captioning by Warburg himself. This publication was in no small part encouraged by the resurgence of interest in the works of Walter Benjamin (1892–1940), whose theories of media and history had come to seem prescient, particularly in the Anglophone world, with the 1969 Illuminations, edited and introduced by Hannah Arendt and subsequently popularized by John Berger in his 1972 TV series and book, Ways of Seeing. (While Warburg was only peripherally aware of Benjamin during his lifetime, Benjamin sent Warburg a copy of his thesis on Baroque Trauerspiel, or tragic drama, which cited Warburg.) Like Benjamin, who often engaged in leaps of thought and argument by way of metaphorical image rather than logical deduction, Warburg was concerned with Zwischenräume, the spaces in between, as well as something he termed Denkraum, or room for thought.
The style of To the Friend Who Did Not Save My Life is more restrained and controlled than these earlier works, but full of well-noticed contrasting details that combine to create an effect that Guibert—apropos of The Compassion Protocol, his last work before his suicide in 1991—characterized as “barbarous and delicate.” An ambulance pulls up to unload a patient in front of a half-abandoned hospital in the midst of shutting down: “slippers in a crate with ampules of potassium chloride . . . a basin from an intensive care unit with a coating of snow on the bottom.” At another hospital, the nurses who draw his blood for the dreaded regular T-cell count “slip on their latex gloves as though they were velvet gloves for a gala evening at the opera.” One of them comments on his cologne, “It’s Habit Rouge isn’t it? . . . I do like that perfume, and to catch a whiff of it on this gray morning, well, you know it’s really a little treat for me.” Disease, as those who’ve spent time in the presence of the sick know, is never quite dramatically life or death, but always life in death and death in life. No moment of one’s life as a terminally ill person or a carer for a terminally ill person passes without this double acknowledgment.

Human beings typically don’t leave the nest until well into our teenage years—a relatively rare strategy among animals. But corvids—a group of birds that includes jays, ravens, and crows—also spend a lot of time under their parents’ wings. Now, in a parallel to humans, researchers have found that ongoing tutelage by patient parents may explain how corvids have managed to achieve their smarts. Corvids are large, big-brained birds that often live in intimate social groups of related and unrelated individuals. They are known to be intelligent—capable of 
In The Weil Conjectures Karen Olsson presents her remarkable subjects as creatures from a fairy tale: “Once there were a brother and sister who devoted themselves to the search for truth. A brother who spent his long life solving problems. A sister who died before she could solve the problem of life.” The sister was Simone Weil (pronounced “vay”), a philosopher and political activist who died in 1943 at age thirty-four and gained fame with the posthumous publication of works, assembled from her voluminous notebooks, on society, justice, and the mystical life of faith. Her elder brother André, who lived to ninety-two, was a prodigy who became one of the twentieth century’s preeminent mathematicians.

If we’re talking about culture that makes people happy, we have to start with the works of PG Wodehouse. There are two reasons why. One reason is that making people happy was Wodehouse’s overriding ambition. The other reason is that he was better at it than any other writer in history.
What does it mean to be great? Whom shall we call great? How can we become great? Is greatness the same as goodness? These questions involve fundamental ethical assumptions, concepts and concerns. Like many who addressed such issues in the past, we often use virtues — courage, generosity, forbearance, etc. — in order to explain what greatness means, reflecting a common notion that greatness requires moral integrity. Virtues describe our ambitions and aspirations, as individuals and as communities. How we give credit for moral achievements is presumably also culturally conditioned, just as the way we relate to our accomplishments in general reflects social and historical context. Studies on the Dunning-Kruger effect suggest that while North Americans regularly overestimate their abilities, in Japan the opposite appears to be the case. Other variables too are sometimes debated. The self-citation rate among male scientists is often reported to be higher than among their female peers, which might reflect a higher estimation of their achievements. Differences are also believed to be generational and related to educational practices around appreciation and rewards. Recent public debates have shed light on the psychological and emotional costs of self-optimizing and the social and political dynamics of virtue-signaling. Likewise, who our role models should be and how they are selected often reveals the diverging views of greatness in a society. Even a brief survey of these and similar discussions suggests that the philosophical problem of greatness can be of significant interest to contemporary readers.
The cultured and literate Amedeo Modigliani (1884-1920) was passionately interested in and emotionally involved with Italian and French poetry of the past as well as with the work of his friends, Anna Ahkmatova, Max Jacob and Blaise Cendrars. On the 100th anniversary of his tragic death in 1920 we can see how the poets who fascinated him portrayed the pain of sex and love, the exaltation of art, the effect of narcotics on creativity and the need to suffer extreme experience. They encouraged his compulsion to live dangerously, and taught him to see the artist as victim, outcast and superman. They provided intellectual justification for the deliberate derangement of his senses and glorified his devotion to art. He didn’t just read poets. He lived according to their principles as if they were imprinted on his body as well as in his mind. These powerful poets both inspired his work and—as he was drawn to disaster and followed their maniacal descent–helped to destroy him.
