What our use of animal-based slurs and endearments says about us

What our use of animal-based slurs and endearments says about us

David Egan writes: Human hatreds take on a depressing variety of forms: in addition to individual hatreds, the world roils with xenophobia, racism, misogyny, homophobia, transphobia, and on and on and on. Less remarked upon is an underlying zoophobia – a fear of, or antipathy towards, animals – that’s manifest in many of the slurs and insults directed at other human beings. Calling a person an animal is usually a comment on their unrestrained appetites, especially for food (‘like a…

How the Pentagon started taking UFO’s seriously

How the Pentagon started taking UFO’s seriously

Gideon Lewis-Kraus writes: Leslie Kean is a self-possessed woman with a sensible demeanor and a nimbus of curly graying hair. She lives alone in a light-filled corner apartment near the northern extreme of Manhattan, where, on the wall behind her desk, there is a framed black-and-white image that looks like a sonogram of a Frisbee. The photograph was given to her, along with chain-of-custody documentation, by contacts in the Costa Rican government; in her estimation, it is the finest image…

To be fully human we must also be fully embodied animal

To be fully human we must also be fully embodied animal

Melanie Challenger writes: When I visited my grandmother at the undertakers, an hour or so before her funeral, I was struck by how different death is from sleep. A sleeping individual shimmers with fractional movements. The dead seem to rest in paused animation, so still they look smaller than in life. It’s almost impossible not to feel as if something very like the soul is no longer present. Yet my grandmother had also died with Alzheimer’s. Even in life, something…

Africa’s forest elephants are just a step from extinction

Africa’s forest elephants are just a step from extinction

The New York Times reports: While some African elephants parade across the savanna and thrill tourists on safari, others are more discreet. They stay hidden in the forests, eating fruit. “You feel pretty lucky when you catch sight of them,” said Kathleen Gobush, a Seattle-based conservation biologist and member of the African Elephant Specialist Group within the International Union for Conservation of Nature, or I.U.C.N. The threat of extinction has diminished the odds of spotting one of these wood-dwelling elephants…

What is life? Its vast diversity defies easy definition

What is life? Its vast diversity defies easy definition

Carl Zimmer writes: “It is commonly said,” the scientists Frances Westall and André Brack wrote in 2018, “that there are as many definitions of life as there are people trying to define it.” As an observer of science and of scientists, I find this behavior strange. It is as if astronomers kept coming up with new ways to define stars. I once asked Radu Popa, a microbiologist who started collecting definitions of life in the early 2000s, what he thought…

An ancient Greek approach to risk and the lessons it can offer the modern world

An ancient Greek approach to risk and the lessons it can offer the modern world

Nudell, Westminster College Most of us take big and small risks in our lives every day. But COVID-19 has made us more aware of how we think about taking risks. Since the start of the pandemic, people have been forced to weigh their options about how much risk is worth taking for ordinary activities – should they,…

John Keats’ concept of ‘negative capability’ – or sitting in uncertainty – is needed now more than ever

John Keats’ concept of ‘negative capability’ – or sitting in uncertainty – is needed now more than ever

The gravestone of John Keats in Rome’s ‘non-Catholic’ cemetery. Dan Kitwood/Getty Images By Richard Gunderman, Indiana University When John Keats died 200 years ago, on Feb. 23, 1821, he was just 25 years old. Despite his short life, he’s still considered one of the finest poets in the English language. Yet in addition to masterpieces such as “Ode to a Nightingale” and “To Autumn,” Keats’ legacy includes a remarkable concept: what he called “negative capability.” The idea – which centers…

What makes Elon Musk and Carl Sagan worlds apart

What makes Elon Musk and Carl Sagan worlds apart

Shannon Stirone writes: There’s no place like home—unless you’re Elon Musk. A prototype of SpaceX’s Starship, which may someday send humans to Mars, is, according to Musk, likely to launch soon, possibly within the coming days. But what motivates Musk? Why bother with Mars? A video clip from an interview Musk gave in 2019 seems to sum up Musk’s vision—and everything that’s wrong with it. In the video, Musk is seen reading a passage from Carl Sagan’s book Pale Blue…

The unified cosmic vision of Alexander von Humboldt

The unified cosmic vision of Alexander von Humboldt

Algis Valiunas writes: The presiding scientific genius of the Romantic age, when science had not yet been dispersed into specialties that rarely connect with one another, Alexander von Humboldt wanted to know everything, and came closer than any of his contemporaries to doing so. Except for Aristotle, no scientist before or since this German polymath can boast an intellect as universal in reach as his and as influential for the salient work of his time. His neglect today is unfortunate…

Human-made stuff now outweighs every living thing on Earth

Human-made stuff now outweighs every living thing on Earth

ScienceAlert reports: All of the Amazon’s splendid greenery. Every fish in the Pacific. Every microbe underfoot. Every elephant on the plains, every flower, fungus, and fruit-fly in the fields, no longer outweighs the sheer amount of stuff humans have made. Estimates on the total mass of human-made material suggest 2020 is the year we overtake the combined dry weight of every living thing on Earth. Go back to a time before humans first took to ploughing fields and tending livestock,…

Signs of recent volcanic eruption on Mars hint at habitats for life

Signs of recent volcanic eruption on Mars hint at habitats for life

The New York Times reports: Mars was once home to seas and oceans, and perhaps even life. But our neighboring world has long since dried up and its atmosphere has been blown away, while most activity beneath its surface has long ceased. It’s a dead planet. Or is it? Previous research has hinted at volcanic eruptions on Mars 2.5 million years ago. But a new paper suggests an eruption occurred as recently as 53,000 years ago in a region called…

Pope Francis: A crisis reveals what is in our hearts

Pope Francis: A crisis reveals what is in our hearts

Pope Francis writes: In this past year of change, my mind and heart have overflowed with people. People I think of and pray for, and sometimes cry with, people with names and faces, people who died without saying goodbye to those they loved, families in difficulty, even going hungry, because there’s no work. Sometimes, when you think globally, you can be paralyzed: There are so many places of apparently ceaseless conflict; there’s so much suffering and need. I find it…

‘Pristine’ extraterrestrial organic compounds found on meteorite may shed light on origin of life on Earth

‘Pristine’ extraterrestrial organic compounds found on meteorite may shed light on origin of life on Earth

Vice reports: On a dark winter night in 2018, hundreds of people across the Great Lakes region witnessed a radiant meteor brighten the skies. Mere days after the fireball streaked overhead on that night in January, scientists were able to track down precious pieces of the ancient space rock using weather radar reports. The scattered remnants of the object, known as the Hamburg meteorite, contain a “high diversity” of extraterrestrial organic compounds that are preserved “in a pristine condition,” according…

Migratory bird flies non-stop over 7,500 miles from Alaska to New Zealand

The Guardian reports: A bird said to have the aerodynamic build of a “jet fighter” has been tracked flying more than 12,000km (7,500 miles) from Alaska to New Zealand, setting a new world record for avian non-stop flight. The bar-tailed godwit set off from south-west Alaska on 16 September and arrived in a bay near Auckland 11 days later, having flown at speeds of up to 55mph. The male bird, known as 4BBRW in reference to the blue, blue, red…

The molecular biologist, Jacques Monod, saw chance as one of the ‘secrets of life’

Sean B. Carroll writes: Jacques Monod arrived in Paris to some dreadful news. On June 5, 1944, four years into the German occupation of France during World War II, he was supposed to meet with fellow leaders in the French Resistance when his assistant, Geneviève Noufflard, told him that several commanders within the greater Paris region had just been caught by the Gestapo. Monod was pretty sure that at least one of those arrested knew about the rendezvous he was…
