Caring about the unborn should mean caring about the future of our planet

Caring about the unborn should mean caring about the future of our planet

William MacAskill writes: Humanity, today, is in its adolescence. Most of a teenager’s life is still ahead of them, and their decisions can have lifelong effects. Similarly, most of humanity’s life lies ahead – an estimated 118 billion people have already lived, but vastly more people, perhaps thousands or even millions of times that number, are yet to be born. And some of the decisions we make this century will impact the entire course of humanity’s future. Contemporary society does…

The geometry of life

The geometry of life

The New York Times reports: In June, 100 fruit fly scientists gathered on the Greek island of Crete for their biennial meeting. Among them was Cassandra Extavour, a Canadian geneticist at Harvard University. Her lab works with fruit flies to study evolution and development — “evo devo.” Most often, such scientists choose as their “model organism” the species Drosophila melanogaster — a winged workhorse that has served as an insect collaborator on at least a few Nobel Prizes in physiology…

Explosion of life on Earth linked to heavy metal act at planet’s center

Explosion of life on Earth linked to heavy metal act at planet’s center

The Observer reports: At the centre of the Earth, a giant sphere of solid iron is slowly swelling. This is the inner core and scientists have recently uncovered intriguing evidence that suggests its birth half a billion years ago may have played a key role in the evolution of life on Earth. At that time, our planet’s magnetic field was faltering – and that would have had critical consequences, they argue. Normally this field protects life on the surface by…

Simone de Beauvoir on facing old age and avoiding bad faith

Simone de Beauvoir on facing old age and avoiding bad faith

Kate Kirkpatrick and Sonia Kruks write: Old age is not exactly a time of life that most of us welcome, although globally speaking it is a privilege to reach it. In Western societies, the shocked realisation that we are growing old often fills us with alarm and even terror. As Simone de Beauvoir writes in her magisterial study of the topic, La vieillesse (1970) – translated in the UK as Old Age, and in the US as The Coming of…

Catastrophe drives evolution, but life resides in the pauses

Catastrophe drives evolution, but life resides in the pauses

Renée A Duckworth writes: In certain places around the world – in the Badlands near Drumheller in Alberta, Canada, in the Geulhemmergroeve tunnels in the Netherlands, or in the Hell Creek formation in eastern Montana – you can touch a thin line of rock, and know you are touching the most famous mass extinction event on Earth. This Cretaceous-Paleogene (K-Pg) boundary layer is a seam of clay found all over the world, enriched with iridium – an element that appears…

Cultivating a sense of wonder

Cultivating a sense of wonder

Anelise Chen writes: When the marine biologist Rachel Carson was a young girl, she discovered a fossilized shell while hiking around her family’s hillside property in Springdale, Pennsylvania. Those who knew her then would later contend that this relic sparked such intense reverie in her that she instantly felt a tug toward the sea. What was this ancient creature, and what was the world it had known? Though Carson had never seen the sea herself, she threw herself into its…

Origin of life theory involving RNA–protein hybrid gets new support

Origin of life theory involving RNA–protein hybrid gets new support

Nature reports: Chemists say they have solved a crucial problem in a theory of life’s beginnings, by demonstrating that RNA molecules can link short chains of amino acids together. The findings, published on 11 May in Nature, support a variation on the ‘RNA world’ hypothesis, which proposes that before the evolution of DNA and the proteins it encodes, the first organisms were based on strands of RNA, a molecule that can both store genetic information — as sequences of the…

The interdependence of all things

The interdependence of all things

Nicholas Cannariato writes: The nature of time. Black holes. Ancient philosophers. The struggle for democracy. Climate change. Buddhist philosophy. In his new collection of essays and articles, Carlo Rovelli, one of the world’s most renowned physicists, broadens his writing to include questions of politics, justice and how we live now. “I look at myself as much more than a physicist,” he said in an interview at his home in London, Ontario, on a cold, calm day in February. The new…

Indian court rules nature has legal status on par with humans. We are required to protect it

Indian court rules nature has legal status on par with humans. We are required to protect it

Inside Climate News reports: The highest court in one of India’s 28 states ruled last month that “Mother Nature” has the same legal status as a human being, which includes “all corresponding rights, duties and liabilities of a living person.” The decision from Madras High Court, located in the southeastern state of Tamil Nadu, also said that the natural environment is part of the human right to life, and that humans have an environmental duty to future generations. “The past…

Ten practical ways to improve happiness

Ten practical ways to improve happiness

Arthur C. Brooks writes: Here’s some very bad happiness advice based on very solid happiness research: Feel important. Be happily married. Be Danish. Depending on how happiness is measured, all of these things really are associated with a happier life. But they’re unhelpful because they are not actionable in any practical way. Very few people slap their foreheads and say, “It all makes sense now—I thought a tense, angry marriage was the secret to happiness, but it isn’t!” This is…

The courage to speak the truth

The courage to speak the truth

Timothy Snyder writes: Once, after a debate in 2009 in Bratislava, I looked over at the notes that the Czech thinker (and by then former president) Václav Havel had been keeping for himself. He had written “love and truth” on a sheet of paper, and then doodled flowers around it. Havel was the author of a famous secular east European statement about risk in politics. He wrote “Power of the Powerless” in communist Czechoslovakia, three decades before that debate, under…

The beauty of life

The beauty of life

Joshua Hicks and Frank Martela write: When we think about lives filled with meaning, we often focus on people whose grand contributions benefited humanity. Abraham Lincoln, Martin Luther King, Jr., and Nelson Mandela surely felt they had a worthwhile life. But how about us ordinary people, toiling away in a typical existence? Many scholars agree that a subjectively meaningful existence often boils down to three factors: the feeling that one’s life is coherent and “makes sense,” the possession of clear…

The impatience of Job

The impatience of Job

Abraham Riesman writes: No one has ever known quite what to make of Job. The title character of the Book of Job is a confounding figure for Christians, Muslims, Jews, and those of any faith who have tried to incorporate the story over millennia. The tale goes like this: Job is a perfectly righteous and God-fearing man whose good deeds have brought him prosperity—children, an estate, good health. But then God enters a wager with a member of the Heavenly…

Laws of nature are impossible to break, and nearly as difficult to define

Laws of nature are impossible to break, and nearly as difficult to define

Marc Lange writes: In the original Star Trek, with the Starship Enterprise hurtling rapidly downward into the outer atmosphere of a star, Captain James T Kirk orders Lt Commander Montgomery Scott to restart the engines immediately and get the ship to safety. Scotty replies that he can’t do it. It’s not that he refuses to obey the Captain’s order or that he doesn’t happen to know how to restart the engines so quickly. It’s that he knows that doing so…

Peptides on stardust may have provided a shortcut to life

Yasemin Saplakoglu writes: Billions of years ago, some unknown location on the sterile, primordial Earth became a cauldron of complex organic molecules from which the first cells emerged. Origin-of-life researchers have proposed countless imaginative ideas about how that occurred and where the necessary raw ingredients came from. Some of the most difficult to account for are proteins, the critical backbones of cellular chemistry, because in nature today they are made exclusively by living cells. How did the first protein form…

Satisfaction has nothing to do with achievement, money, or stuff

Arthur C Brooks writes: Abd al-Rahman III, the emir and caliph of Córdoba in 10th-century Spain, summed up a life of worldly success at about age 70: “I have now reigned above 50 years in victory or peace; beloved by my subjects, dreaded by my enemies, and respected by my allies. Riches and honors, power and pleasure, have waited on my call.” And the payoff? “I have diligently numbered the days of pure and genuine happiness which have fallen to…
