Nicholas Humphrey writes: The cover of New Scientist magazine 50 years ago showed a picture of a rhesus monkey, with the headline ‘A Blind Monkey That Sees Everything’. The monkey, named Helen, was part of a study into the neuropsychology of vision, led by Lawrence (Larry) Weiskrantz in the psychology laboratory at the University of… Read More »
Science Alert reports: In the middle of the night, the world can sometimes feel like a dark place. Under the cover of darkness, negative thoughts have a way of drifting through your mind, and as you lie awake, staring at the ceiling, you might start craving guilty pleasures, like a cigarette or a carb-heavy meal.… Read More »
Martha Henriques writes: It was a big night for Inky the octopus. The day’s visitors had been and gone, and now his room in the aquarium was deserted. In a rare oversight, the lid of his tank had been left ajar. The common New Zealand octopus had been without female company for some time, sharing… Read More »
Laura Miller writes: John James Audubon was wrong. The great naturalist may have illustrated and compiled 1827’s Birds of America, a pioneering work of ornithology, but thanks to a series of sloppy experiments on turkey vultures, he insisted that birds can’t smell. This was taken for granted until the 1960s when two women scientists in… Read More »
Matthew Hutson writes: A couple of decades ago, on a backpacking trip in the Sierra Nevada, I was marching up a mountain solo under the influence of LSD. Halfway to the top, I took a break near a scrubby tree pushing up through the rocky soil. Gulping water and catching my breath, I admired both… Read More »
ABC News (AU) reports: Up until the mid-1980s, human babies didn’t feel pain. Of course that’s not actually true, but due to research conducted in the 18th and early 19th centuries, it was an attitude that still lingered among a small minority of scientists and medical professionals. So much so that some infant surgery was… Read More »
Tom Chatfield writes: If you woke up one day and discovered that you were living in a virtual world – that everything you’d ever known was, like the Matrix, a form of hyper-realistic simulation – what would this imply for your hopes, dreams and experiences? Would it reveal them all to be lies: deceptions devoid… Read More »
Antonio Damasio writes: In the beginning was not the word; that much is clear. Life sailed forth without words or thoughts, without feelings or reasons, devoid of minds or consciousness. Not that the universe of the living was ever simple, quite the contrary. It was complex from its inception, four billion years ago. But living… Read More »
Johann Hari writes: I went to Portland, Oregon, to interview Prof Joel Nigg, who is one of the leading experts in the world on children’s attention problems, and he told me we need to ask if we are now developing “an attentional pathogenic culture” – an environment in which sustained and deep focus is harder… Read More »
Anil Seth writes: In 2022 we will see brain organoids displaying dynamics that bear comparison with the complex activity patterns indicative of consciousness in humans. This will require us to rethink what counts as a brain signature of “consciousness” and will raise serious ethical issues about brainlike structures grown in the lab. Brain organoids are… Read More »
Morten L Kringelbach writes: The execution of any musical symphony is a difficult task, demanding significant skills from each musician. Perhaps the hardest task lies with the conductor who must orchestrate the musicians so the music comes alive cohesively and speaks to our deepest emotions. The human brain is like an orchestra: different regions perform… Read More »
Susana Monsó writes: Humans have long thought of themselves as the only animal with a notion of mortality. Our concept of death is one of those characteristics, like culture, rationality, language or morality, that have traditionally been taken as definitional of the human species – setting us apart from the natural world and justifying our… Read More »
Nicholas P Money writes: Mushrooms and other kinds of fungi are often associated with witchcraft and are the subjects of longstanding superstitions. Witches dance inside fairy rings of mushrooms according to German folklore, while a French fable warns that anyone foolish enough to step inside these ‘sorcerer’s rings’ will be cursed by enormous toads with… Read More »
Tam Hunt writes: How does consciousness arise? What might its relationship to matter be? And why are some things conscious while others apparently aren’t? These sorts of questions, taken together, make up what’s called the “hard problem” of consciousness, coined some years ago by the philosopher David Chalmers. There is no widely accepted solution to… Read More »
Ferris Jabr writes: In Vogue’s 1969 Christmas issue, Vladimir Nabokov offered some advice for teaching James Joyce’s “Ulysses”: “Instead of perpetuating the pretentious nonsense of Homeric, chromatic, and visceral chapter headings, instructors should prepare maps of Dublin with Bloom’s and Stephen’s intertwining itineraries clearly traced.” He drew a charming one himself. Several decades later, a… Read More »
Simona Ginsburg and Eva Jablonka write: MuZero is an algorithm with a superhuman ability to learn: it has learned to play 57 different Atari video games as well as Chess, Go and Shogi, and defeated the greatest human masters in every one of them. Yet, this amazing algorithm and the computer in which it is… Read More »
