Scientists observe a surge of activity correlated with consciousness in the dying brain

PsyPost reports: A recent study published in the Proceedings of the National Academy of Sciences has presented preliminary findings suggesting there can be a surge of brain activity linked to consciousness during the dying process. The new study aimed to investigate the brain activity of patients during the dying process, particularly focusing on whether there are any neural correlates of consciousness. Near-death experiences (NDEs) have been reported by some cardiac arrest survivors and are described as highly vivid and real-like…

The lies mothers tell themselves and their children

The lies mothers tell themselves and their children

Elise Loehnen writes: As Carl Jung famously said, nothing is more influential in a child’s life than the unlived life of the parent. My mother’s unlived life ricochets inside my life. My mom is an ardent reader — it’s probably no coincidence that my brother is a book editor and I make my living with words. And like her, I have children — but I wanted mine. In this anxious inheritance from my mother and my grandmother, I’ve both under-…

A new idea for how to assemble life

A new idea for how to assemble life

Philip Ball writes: Assembly theory makes the seemingly uncontroversial assumption that complex objects arise from combining many simpler objects. The theory says it’s possible to objectively measure an object’s complexity by considering how it got made. That’s done by calculating the minimum number of steps needed to make the object from its ingredients, which is quantified as the assembly index (AI). In addition, for a complex object to be scientifically interesting, there has to be a lot of it. Very…

Is abortion sacred?

Is abortion sacred?

Jia Tolentino writes: Twenty years ago, when I was thirteen, I wrote an entry in my journal about abortion, which began, “I have this huge thing weighing on me.” That morning, in Bible class, which I’d attended every day since the first grade at an evangelical school, in Houston, my teacher had led us in an exercise called Agree/Disagree. He presented us with moral propositions, and we stood up and physically chose sides. “Abortion is always wrong,” he offered, and…

Why life is not a thing but a restless manner of being

Why life is not a thing but a restless manner of being

Tim Requarth writes: Mike Russell found his moment of inspiration on a warm spring evening in Glasgow in 1983, when his 11-year-old son broke a new toy. The toy in question was a chemical garden, a small plastic tank in which stalagmite-like tendrils grew out of seed crystals placed in a mineral solution. Although the tendrils appeared solid from the outside, when shattered they revealed their true nature: each one was actually a network of hollow tubes, like bundles of…

What hunter-gatherers demonstrate about work and satisfaction

What hunter-gatherers demonstrate about work and satisfaction

Vivek V Venkataraman writes: I once drove through Peninsular Malaysia with an economist friend to visit the Batek [a small group of hunter-gatherers]. Along the way, we travelled through endless plantations of palm oil. Now and then, we came across gigantic tree stumps, poignant reminders of a former world. Palm oil plantations contain living and breathing trees but, in fact, they are just deserts of green, virtually devoid of life. I bemoaned the staggering loss of biodiversity. Then, to my…

Why we will never be able to live on another planet

Why we will never be able to live on another planet

Arwen E Nicholson and Raphaëlle D Haywood write: For decades, children have grown up with the daring movie adventures of intergalactic explorers and the untold habitable worlds they find. Many of the highest-grossing films are set on fictional planets, with paid advisors keeping the science ‘realistic’. At the same time, narratives of humans trying to survive on a post-apocalyptic Earth have also become mainstream. Given all our technological advances, it’s tempting to believe we are approaching an age of interplanetary…

The Romantics who laid the foundations of modern consciousness

The Romantics who laid the foundations of modern consciousness

Andrea Wulf writes: In September 1798, one day after their poem collection Lyrical Ballads was published, the poets Samuel Taylor Coleridge and William Wordsworth sailed from Yarmouth, on the Norfolk coast, to Hamburg in the far north of the German states. Coleridge had spent the previous few months preparing for what he called ‘my German expedition’. The realisation of the scheme, he explained to a friend, was of the highest importance to ‘my intellectual utility; and of course to my…

Why we need to be seen and not herded

Why we need to be seen and not herded

Costica Bradatan writes: Have you noticed how, when crossing a busy road, you feel a sudden urge to speed up and melt into the crowd? Whether you are in Rio de Janeiro or Bangkok, New Delhi or New York City, your animal instinct tells you that it is safer to venture as part of a herd than on your own. Fear brings us closer together. The evidence is not just anecdotal. When we are herding, neuroimaging experiments show increased activation…

As Gen X and Boomers age, they confront living alone

As Gen X and Boomers age, they confront living alone

The New York Times reports: Jay Miles has lived his 52 years without marriage or children, which has suited his creative ambitions as a videographer in Connecticut and, he said, his mix of “independence and stubbornness.” But he worries about who will take care of him as he gets older. Donna Selman, a 55-year old college professor in Illinois, is mostly grateful to be single, she said, because her mother and aunts never had the financial and emotional autonomy that…

We are interwoven beings

We are interwoven beings

Mercedes Valmisa writes: What if I told you that there’s no such thing as an individual action? That every time you eat, walk up the stairs or read a book, you are not the sole agent behind what you are doing, but are engaged in a process of co-creation – as much acted-upon as acting? To grasp what I mean here, imagine riding a horse. While I can effortlessly distinguish between myself and a horse, I’m aware that neither I…

Why doesn’t physics help us understand the flow of time?

Gene Tracy writes: I have a memory, a vivid one, of watching my elderly grandfather wave goodbye to me from the steps of a hospital. This is almost certainly the memory of a dream. In my parent’s photo album of the time, we have snapshots of the extended family – aunts, uncles, and cousins who had all travelled to our upstate New York farm to celebrate my grandparents’ 50th wedding anniversary. I am in some of the photos along with…

Human exceptionalism imposes horrible costs on other animals

Human exceptionalism imposes horrible costs on other animals

Barbara J King writes: Human exceptionalism takes many forms but most share an assumption that our species displays singularly complex ways of being, thinking and feeling. On this perspective, other animals’ capacities are inferior, and so other animals’ lives are also seen as inferior. It’s only a myth, though, that other-than-human animals inevitably live moment to moment. Many mammals and birds remember and learn from past experiences, and anticipate with joy or fear what may be coming next. Recognition of…

Of Gandhi’s few possessions, his watches were the most beloved

Of Gandhi’s few possessions, his watches were the most beloved

Nina Martyris writes: The watch never left his side. It was the first thing Gandhi reached for when he rose each morning at 4 a.m., and the last thing he checked before going to bed, often past midnight. He consulted it frequently through the day so as never to be late for an appointment. And, at that final moment, when three bullets from an assassin’s Beretta knocked him over, his 78-year-old body slumped to the ground, and the watch also…

Nick Lane is asking — and answering — vital questions about life

Nick Lane is asking — and answering — vital questions about life

Philip Ball writes: “There is a black hole at the heart of biology,” Nick Lane writes at the start of his 2015 book The Vital Question. “Bluntly put, we do not know why life is the way it is.” It takes some chutzpah to lay down the gauntlet to the life sciences so starkly—to suggest they are engaged more in documenting life than in explaining it. Lane, a professor of evolutionary biochemistry at University College London, doesn’t seem the kind…

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…
