Ryan A Bush writes: In 1882, Friedrich Nietzsche published The Gay Science, a work he referred to as ‘the most personal of all my books’. It came after a series of setbacks in his life, including the weak reception of his previous work, a soured friendship, and his declining health, which caused severe migraines and vomiting,… Read More »
Yasemin Saplakoglu writes: Scientists have debated why life became homochiral [that is, having molecular asymmetry], and whether it needed to happen or if it was purely a fluke. Were chiral preferences impressed on early life by biased samples of molecules arriving from space, or did they somehow evolve out of mixtures that started out as… Read More »
Olivia Judson writes: I want to start with a proposition: if Earth had never come alive, it would be a profoundly different world. Conversely: the planet of today has, to a remarkable extent, been made what it is by the activities of lifeforms. Over the course of the planet’s long history, a history that extends… Read More »
Robert S Gable writes: Everyone dies sometime. But when and how? Those questions become more salient as birthdays roll by. It has been said that wherever old people gather there is an ‘organ recital’ of malfunctioning body organs and parts. I, too, have a recital. Last year, at age 88, I woke up in a… Read More »
Lina Zeldovich writes: Floating in the middle of our galaxy, near the center of the Milky Way, inside a cloud of gas that swirls at the temperature of 100 Kelvin or -279.67 Fahrenheit, a molecule essential to life on Earth has just been discovered. It sounds inconceivable that such a level of cosmic cold could… Read More »
Terry Tempest Williams writes: On the 50th anniversary of the Endangered Species Act, I am thinking about extinction and what that means for a creature, a living being, to vanish from existence. Say their names: great auk, passenger pigeon, Carolina parakeet, Steller’s sea cow, Caribbean monk seal, Great Plains wolf, Puerto Rican long-nosed bat, Maryland… Read More »
Science Alert reports: Biologists usually define ‘life’ as an entity that reproduces, responds to its environment, metabolizes chemicals, consumes energy, and grows. Under this model, ‘life’ is a binary state; something is either alive or not. This definition works reasonably well on planet Earth, with viruses being one notable exception. But if life is elsewhere… Read More »
The Washington Post reports: Saturn’s moon Enceladus has enticed scientists for years with its plumes fizzing their way up from an ocean beneath a thick crust of ice. Now there’s a new element to the story, literally: That cold, dark ocean appears to contain a form of phosphorus, an essential ingredient for life as we… Read More »
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… Read More »
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… Read More »
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… Read More »
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… Read More »
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… Read More »
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… Read More »
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… Read More »
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… Read More »
