Human Intelligence Is Fundamentally Different From Machine Intelligence
Design theorist William Dembski discusses the problems we will encounter when we try to integrate the two when, say, sharing the road with self-driving carsBacteria Have Memories? Well, That’s What Some Researchers Found…
Researchers at the University of Texas at Austin have found that bacteria can store and pass on memories of past actions — such as creating infections in humans — for about four to seven generations: Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface. The discovery — which has potential applications for preventing and combatting bacterial infections and addressing antibiotic-resistant bacteria — relates to a common chemical element bacterial cells can use to form and pass along these memories to their progeny over later generations.

Are Good Ideas Hard to Find?
This academic paper tells us a lot about why innovation has slowedFew would disagree that ideas are important to innovation and productivity growth. They are needed for new products, processes, and methods for their conception, introduction, and diffusion. One challenge is how new ideas fit together to enable positive outcomes. Is the initial idea for the concept the most important, the ideas for the implementation, or those for the many problems that must be solved over the course of a technology’s lifetime in order that the technology becomes better in any way we define better? An economics paper by researchers from Stanford and MIT tries to make sense of these issues. Published in the American Economic Review, the paper analyzes the number of researchers needed to achieve improvements in the number of Read More ›
Beauty is Non-Computable
Taking some time to reflect on the beautiful things in the world can lead to genuine thanksgiving.Octopus Intelligence Shakes Up Darwin’s Tree
There does not seem to be a Tree of Intelligence, which deepens the mystery of intelligenceDo Cool Floor Buttons Really Cause Dogs To Talk?
The latest fad in “Talk to the animals” appears to be a classic in confirmation biasHow a Toddler in a Toy Store Refutes Materialism
This everyday observation yields insight into a fundamental truthI’m a magnet for materialists. I often get into discussions with people who tell me that the universe is nothing but matter and energy. These folks believe in materialism. They say I’m nutty and wrong to think there is anything else. Something like: “Silly theist! Gods are for kids!” Let’s follow that thought. A grandparent of 11 humans, I’ve journeyed with their parents through the young ones’ toddlerhood many times. There’s a lot to learn about reality from toddlers’ learning and growing. It leads to understanding Toddler Truth. Take a toddler to a game arcade, a toy store, or another kid’s house to play. There’s one thing you can count on hearing: “I want that!” We parents start tuning out Read More ›
Was the Tyrannosaur as Smart as a Monkey? Assessing a New Claim
One researcher argues that, based on bird studies, the huge predators may have had many more brain cells than we have supposedVanderbilt University neuroscientist Suzana Herculano-Houzel tells us, in a recent paper, that tyrannosaurs had similar numbers of brain neurons as “primates.” But how would we know? Herculano-Houzel stats with the assumption that dinosaurs are descended from birds and makes a distinction between the theropod dinosaurs like the tyrannosaur and others: From that assumption, Herculano-Houzel realized that theropods in particular had a similar correlation between body mass and brain size to pre-impact birds, or basal birds. From there, she used the neuron count of modern birds like emus and ostritches and applied the same rules of scaling to figure out how many neurons theropods like the T-Rex may have had. Frank Landymore, “In terrifying news, big brained T-rex may have been Read More ›
1000 Dogs Tested on Standardized Dog IQ test. What Was Found?
There were no breed differences for short-term memory or logical reasoning but some differences in how much they needed to interact with humans when problem-solvingAssessing dog intelligence is one of those sensitive areas because of the difficulty in agreeing on what to measure. Experts tend to say that border collies are the smartest dog breed but the response they may get is, “My shih tzu understands me and I am a difficult person to understand!” Nonetheless, a Finnish research group decided to try their hand at administering a battery of standardized intelligence tests (smartDOG) to over 1000 dogs between 1 and 8 years old, of 13 different breeds, with a minimum of 40 dogs from each breed. Here’s what they were testing for: The battery involves measuring different cognitive traits, from spatial problem solving to logical reasoning, to impulse control and an ability to Read More ›
Study: Monkeys, Not Humans, Likely Made Ancient Brazilian Tools
The stone objects, dated from 50,000 years ago, look like the ones made by capuchin monkeys todayThere’s a danger in looking too hard for evidence of our ancient ancestors. Sometimes we could be seeing things that aren’t there. One group of stone tools from 50,000 years ago could, it is now suggested, have been made by monkeys: Excavations at Pedra Furada, a group of 800 archaeological sites in the state of Piauí, Brazil, have turned up stone shards believed to be examples of simple stone tools. Made from quartzite and quartz cobbles, the oldest ones appear to be up to 50,000 years old, which would put them among the earliest evidence of human habitation in the Western Hemisphere. However, the tools also bear a striking resemblance to the stone tools currently made by the capuchin monkeys Read More ›
Can Animals Be Held Criminally Responsible for Their Acts?
While the idea is handled provocatively in philosophy literature, in practice, animals are envisioned as plaintiffs, not defendants, in animal rights casesIn an essay at Psyche, Ed Simon, a journalist who investigates the eclectic, looks at the history/mythology of trying animals like pigs and rats for criminal offenses. He sees an opportunity there for animal rights activism: Dismissing animal trials as just another backwards practice of a primitive time is to our intellectual detriment, not only because it imposes a pernicious presentism on the past, but also because it’s worth considering whether or not the broader implications of such a ritual don’t have something to tell us about different ways of understanding nonhuman consciousness, and the rights that our fellow creatures deserve. From our metaphysics, then, can come our ethics, and from our ethics can derive politics and law. There need Read More ›
Do Animals, as Well as Humans, Have Free Will?
One can make a case for animal free will in the strict sense that no life form is bound by complete determinism because it doesn't existIn 2009, University of Würzburg biology professor Martin Heisenberg wrote a defense of animal free will in Nature, basing his argument on the behavior of flies: For example, my lab has demonstrated that fruit flies, in situations they have never encountered, can modify their expectations about the consequences of their actions. They can solve problems that no individual fly in the evolutionary history of the species has solved before. Our experiments show that they actively initiate behaviour4. Like humans who can paint with their toes, we have found that flies can be made to use several different motor outputs to escape a life-threatening danger or to visually stabilize their orientation in space. Heisenberg, M. Is free will an illusion?. Nature Read More ›
Spiders Are Smart; Be Glad They Are Small
Recent research has shed light on the intriguing strategies that spiders use to deceive other spiders — and prey in generalThis story was #7 in 2022 at Mind Matters News in terms of reader numbers. As we approach the New Year, we are rerunning the top ten Mind Matters News stories of 2022, based on reader interest. For those of us who wonder whether invertebrates really think — well, it’s complicated because some do more than we expect but then some don’t. At any rate: “Spiders are smart: Be glad they are small. (March 11, 2022) Spiders, like octopuses, have eight legs. But they share something else as well — like octopuses, once we got around to studying them, they turned out to be much smarter than expected. What makes spiders even more unusual is that they are smart with Read More ›
Mice Can’t Do Calculus But Their Brains Can
Neuroimaging and mathematics showed that a simple Stop! signal in the brain would not allow a mouse to stop as quickly as it in fact didScience writer Kevin Hartnett tells us that, based on experiments with mice, the brain sharpens control of precise maneuvers by using comparisons between control signals rather than the signals themselves: [The research] explores a simple question: How does the brain — in mice, humans and other mammals — work quickly enough to stop us on a dime? The new work reveals that the brain is not wired to transmit a sharp “stop” command in the most direct or intuitive way. Instead, it employs a more complicated signaling system based on principles of calculus. This arrangement may sound overly complicated, but it’s a surprisingly clever way to control behaviors that need to be more precise than the commands from the brain Read More ›
Researchers: Dogs Evaluate How Competent Humans Are
Provided that a treat is involved. Females pay more attention to competence in humans than males, they sayAt Scientific American’s “60-Second Science” podcast (with transcript), science writer Karen Hopkin interviewed Kyoto University psychologist Hitomi Chijiiwa on her team’s recent finding that female dogs actively evaluate human competence. Because one their previous studies showed that dogs avoid people who refuse to help their human friends, the team decided to also test whether dogs form judgments about people based on their apparent skilfulness or competence: Chijiiwa: We showed 60 dogs two persons manipulating transparent containers. One person is competent. Hopkin: That person was able to pop open the top after just a couple of twists. Chijiiwa: Whereas the other person is incompetent and they failed at this task. Hopkin: That person tried to open the lid, then gave up. Read More ›
Can a Dog Be Bred To Be As Smart As a Human?
An enterprising electrical engineer thinks it can be doneWithin one hundred generations or roughly 600 years? That’s the project Payton Pearson, an electrical engineer who gives his affiliation as the Air Force Institute of Technology in Dayton, Ohio, has set himself: Artificial selection is a well-known phenomenon of selecting for certain physiological characteristics of various species of plants and animals, and it is something that human beings have been doing for thousands of years. A perfect example of this is the union and development of dogs under human stewardship since the beginning of the agricultural era of society. In that time, approximately 6,000 years [1], dogs have been artificially selected in such a way as to produce thousands of different breeds. From the stout Dachshund, a dog breed Read More ›
Micro RNAs: A New Clue About Octopus Intelligence?
While octopus brains are very different from vertebrate brains, they share with vertebrates, a huge number of microRNAsIn general, the “intelligent” animals (apes, elephants, crows, whales, dogs, dolphins) are vertebrates, not invertebrates. There is one glaring exception: the cephalopods (octopuses, squid, cuttlefish). They, like vertebrates, developed large, complex brains and unexpectedly sophisticated cognitive abilities. When thinking about the puzzle, we sometimes fall victim to a sort of confusion: We reason that greater intelligence results from the fact that it “helps the octopus survive better.” Perhaps it does. But, while greater intelligence might help many life forms survive better, only a few develop it. In short, we need a “how” explanation here, not a “why” explanation. A recent study from the Max Delbrück Center for Molecular Medicine points to the possible role of microRNAs (miRNAs). MicroRNAs (miRNAs) are Read More ›
Do Centaurs Really Exist? The Surprising Truth
Well, a half human/half horse cannot literally exist — but the way horses and humans work together has been called a “miracle”Classical Greek mythology featured the “centaur,” a creature that was half human, half horse. Neuroscientist and horse trainer Janet Jones, author of Horse Brain, Human Brain: The Neuroscience of Horsemanship (Trafalgar Square, 2020), tells us that there is a truth behind the myth (as so often). In what amounts to a “neurobiological miracle,” the horse — a prey animal — and the human — a predator — can learn complete neurological co-operation to perform complex feats that neither can manage alone. How complex are these equestrian feats? Horse-and-human teams perform complex manoeuvres in competitions of all sorts. Together, we can gallop up to obstacles standing 8 feet (2.4 metres) high, leave the ground, and fly blind – neither party able Read More ›
Earliest Brain Found — From Over Half a Billion Years Ago
No one was expecting the Cardiodictyon fossil to have a brainA surprising find for evolutionary neuroscientists is that a tiny life form that lived more than half a billion years ago had a brain. Creatures like Cardiodictyon were not supposed to have had brains: A study published in Science—led by Nicholas Strausfeld, a Regents Professor in the University of Arizona Department of Neuroscience, and Frank Hirth, a reader of evolutionary neuroscience at King’s College London—provides the first detailed description of Cardiodictyon catenulum, a wormlike animal preserved in rocks in China’s southern Yunnan province. Measuring barely half an inch (less than 1.5 centimeters) long and initially discovered in 1984, the fossil had hidden a crucial secret until now: a delicately preserved nervous system, including a brain. University of Arizona, “525-million-year-old fossil Read More ›
