Science reports: In 2021, Google engineer Blake Lemoine made headlines—and got himself fired—when he claimed that LaMDA, the chatbot he’d been testing, was sentient. Artificial intelligence (AI) systems, especially so-called large language models such as LaMDA and ChatGPT, can certainly seem conscious. But they’re trained on vast amounts of text to imitate human responses. So… Read More »
Science Alert reports: New research sheds light on a tricky idea of consciousness: There’s a difference between what the brain takes in and what we’re consciously aware of taking in. Scientists now think they’ve pinpointed the brain region where that conscious awareness is managed. The team, from the Hebrew University of Jerusalem in Israel and… Read More »
Nature reports: A 25-year science wager has come to an end. In 1998, neuroscientist Christof Koch bet philosopher David Chalmers that the mechanism by which the brain’s neurons produce consciousness would be discovered by 2023. Both scientists agreed publicly on 23 June, at the annual meeting of the Association for the Scientific Study of Consciousness… Read More »
Yasemin Saplakoglu writes: Is this the real life? Is this just fantasy? Those aren’t just lyrics from the Queen song “Bohemian Rhapsody.” They’re also the questions that the brain must constantly answer while processing streams of visual signals from the eyes and purely mental pictures bubbling out of the imagination. Brain scan studies have repeatedly… 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 »
Illus_man / Shutterstock By Philip Goff, Durham University There has been shock around the world at the rapid rate of progress with ChatGPT and other artificial intelligence created with what’s known as large language models (LLMs). These systems can produce text that seems to display thought, understanding and even creativity. But can these systems really… Read More »
Antonio Damasio and Hanna Damasio write: Please pause for a moment and notice what you are feeling now. Perhaps you notice a growing snarl of hunger in your stomach or a hum of stress in your chest. Perhaps you have a feeling of ease and expansiveness, or the tingling anticipation of a pleasure soon to… Read More »
David P Barash writes: Few ideas are as unsupported, ridiculous and even downright harmful as that of the ‘human soul’. And yet, few ideas are as widespread and as deeply held. What gives? Why has such a bad idea had such a tenacious hold on so many people? Although there is a large literature on… Read More »
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 »
