      Electroconvulsive therapy may have more adverse effects than thought

      news.movim.eu / TheGuardian • 20 November, 2025

    Study calls for depression treatment to be suspended for more research after reports of heart problems and emotional blunting

    Electroconvulsive therapy could be causing a wider range of adverse effects when used to treat depression than previously understood, according to a paper that calls for the practice to be suspended pending more robust research.

    Although short- and long-term memory loss is widely known to result from ECT, the research identified 25 further concerning side effects, which included cardiovascular problems, fatigue and emotional blunting.

      Pinprick blood test could detect disease 10 years before symptoms appear, study finds

      news.movim.eu / TheGuardian • 20 November, 2025

    Molecular profiles will give detailed snapshot of person’s physiology and predict diseases from diabetes to cancer and dementia

    The world’s largest study into key substances in the bloodstream has paved the way for a swathe of pinprick tests that can detect early signs of disease more than a decade before symptoms appear, researchers say.

    Work on the tests follows the completion of a project by the UK Biobank to measure the levels of nearly 250 different proteins, sugars, fats and other compounds in blood collected from half a million volunteers.

      NASA really wants you to know that 3I/ATLAS is an interstellar comet

      news.movim.eu / ArsTechnica • 20 November, 2025 • 1 minute

    Since early July, telescopes around the world have been tracking just our third confirmed interstellar visitor, the comet 3I/ATLAS—3I, for third interstellar, and ATLAS (Asteroid Terrestrial-impact Last Alert System) for the telescope network that first spotted it. But the object’s closest approach to the Sun came in late October during the US government shutdown. So, while enough people went to work to ensure that the hardware continued to do its job, nobody was available at NASA to make the images available to the public or discuss their implications.

    So today, NASA held a press conference to discuss everything that we now know about 3I/ATLAS, and how NASA’s hardware contributed to that knowledge. And to say one more time that the object is a fairly typical comet and not some spaceship doing its best to appear like one.

    Extrasolar comet

    3I/ATLAS is an extrasolar comet and the third visitor from another star that we’ve detected. We know the comet part because it looks like one, forming a coma of gas and dust, as well as a tail, as the Sun heats up its materials. That hasn’t stopped the usual suspect ( Avi Loeb ) from speculating that it might be a spacecraft, as he had for the earlier visitors. NASA doesn’t want to hear it. “This object is a comet,” said Associate Administrator Amit Kshatrya. “It looks and behaves like a comet, and all evidence points to it being a comet.”

      DeepMind’s latest: An AI for handling mathematical proofs

      news.movim.eu / ArsTechnica • 19 November, 2025

    Computers are extremely good with numbers, but they haven’t gotten many human mathematicians fired. Until recently, they could barely hold their own in high school-level math competitions.

    But now Google’s DeepMind team has built AlphaProof, an AI system that matched silver medalists’ performance at the 2024 International Mathematical Olympiad, scoring just one point short of gold at the most prestigious undergrad math competition in the world. And that’s kind of a big deal.

    True understanding

    The reason computers fared poorly in math competitions is that, while they far surpass humanity’s ability to perform calculations, they are not really that good at the logic and reasoning that is needed for advanced math. Put differently, they are good at performing calculations really quickly, but they usually suck at understanding why they’re doing them. While something like addition seems simple, humans can do semi-formal proofs based on definitions of addition or go for fully formal Peano arithmetic that defines the properties of natural numbers and operations like addition through axioms.

      How Louvre thieves exploited human psychology to avoid suspicion—and what it reveals about AI

      news.movim.eu / ArsTechnica • 19 November, 2025 • 4 minutes

    On a sunny morning on October 19 2025 , four men allegedly walked into the world’s most-visited museum and left, minutes later, with crown jewels worth 88 million euros ($101 million). The theft from Paris’ Louvre Museum—one of the world’s most surveilled cultural institutions—took just under eight minutes.

    Visitors kept browsing. Security didn’t react (until alarms were triggered). The men disappeared into the city’s traffic before anyone realized what had happened.

    Investigators later revealed that the thieves wore hi-vis vests, disguising themselves as construction workers . They arrived with a furniture lift, a common sight in Paris’s narrow streets, and used it to reach a balcony overlooking the Seine. Dressed as workers, they looked as if they belonged.

    This strategy worked because we don’t see the world objectively. We see it through categories—through what we expect to see. The thieves understood the social categories that we perceive as “normal” and exploited them to avoid suspicion. Many artificial intelligence (AI) systems work in the same way and are vulnerable to the same kinds of mistakes as a result.

    The sociologist Erving Goffman would describe what happened at the Louvre using his concept of the presentation of self : people “perform” social roles by adopting the cues others expect. Here, the performance of normality became the perfect camouflage.

    The sociology of sight

    Humans carry out mental categorization all the time to make sense of people and places. When something fits the category of “ordinary,” it slips from notice.

    AI systems used for tasks such as facial recognition and detecting suspicious activity in a public area operate in a similar way. For humans, categorization is cultural. For AI, it is mathematical.

    But both systems rely on learned patterns rather than objective reality . Because AI learns from data about who looks “normal” and who looks “suspicious,” it absorbs the categories embedded in its training data. And this makes it susceptible to bias .

    The Louvre robbers weren’t seen as dangerous because they fit a trusted category. In AI, the same process can have the opposite effect: people who don’t fit the statistical norm become more visible and over-scrutinized.

    It can mean a facial recognition system disproportionately flags certain racial or gendered groups as potential threats while letting others pass unnoticed.

    A sociological lens helps us see that these aren’t separate issues. AI doesn’t invent its categories; it learns ours. When a computer vision system is trained on security footage where “normal” is defined by particular bodies, clothing, or behavior, it reproduces those assumptions.

    Just as the museum’s guards looked past the thieves because they appeared to belong, AI can look past certain patterns while overreacting to others.

    Categorization, whether human or algorithmic, is a double-edged sword. It helps us process information quickly, but it also encodes our cultural assumptions. Both people and machines rely on pattern recognition, which is an efficient but imperfect strategy.

    A sociological view of AI treats algorithms as mirrors: They reflect back our social categories and hierarchies. In the Louvre case, the mirror is turned toward us. The robbers succeeded not because they were invisible, but because they were seen through the lens of normality. In AI terms, they passed the classification test.

    From museum halls to machine learning

    This link between perception and categorization reveals something important about our increasingly algorithmic world. Whether it’s a guard deciding who looks suspicious or an AI deciding who looks like a “shoplifter,” the underlying process is the same: assigning people to categories based on cues that feel objective but are culturally learned.

    When an AI system is described as “biased,” this often means that it reflects those social categories too faithfully. The Louvre heist reminds us that these categories don’t just shape our attitudes, they shape what gets noticed at all.

    After the theft, France’s culture minister promised new cameras and tighter security . But no matter how advanced those systems become, they will still rely on categorization. Someone, or something, must decide what counts as “suspicious behavior.” If that decision rests on assumptions, the same blind spots will persist.

    The Louvre robbery will be remembered as one of Europe’s most spectacular museum thefts. The thieves succeeded because they mastered the sociology of appearance: They understood the categories of normality and used them as tools.

    And in doing so, they showed how both people and machines can mistake conformity for safety. Their success in broad daylight wasn’t only a triumph of planning. It was a triumph of categorical thinking, the same logic that underlies both human perception and artificial intelligence.

    The lesson is clear: Before we teach machines to see better, we must first learn to question how we see.

      UCLA faculty gets big win in suit against Trump’s university attacks

      news.movim.eu / ArsTechnica • 18 November, 2025

    On Friday, a US District Court issued a preliminary injunction blocking the United States government from halting federal funding at UCLA or any other school in the University of California system. The ruling came in response to a suit filed by groups representing the faculty at these schools challenging the Trump administration’s attempts to force UCLA into a deal that would substantially revise instruction and policy.

    The court’s decision lays out how the Trump administration’s attacks on universities follow a standard plan: use accusations of antisemitism to justify an immediate cut to funding, then use the loss of money to compel an agreement that would result in revisions to university instruction and management. The court finds that this plan was deficient on multiple grounds, violating legal procedures for cutting funding to an illegal attempt and suppressing the First Amendment rights of faculty.

    The result is a reprieve for the entire University of California system, as well as a clear pathway for any universities to fight back against the Trump administration’s attacks on research and education.

      Ancient Egyptians likely used opiates regularly

      news.movim.eu / ArsTechnica • 17 November, 2025 • 1 minute

    Scientists have found traces of ancient opiates in the residue lining an Egyptian alabaster vase, indicating that opiate use was woven into the fabric of the culture. And the Egyptians didn’t just indulge occasionally: according to a paper published in the Journal of Eastern Mediterranean Archaeology, opiate use may have been a fixture of daily life.

    In recent years, archaeologists have been applying the tools of pharmacology to excavated artifacts in collections around the world. As previously reported , there is ample evidence that humans in many cultures throughout history used various hallucinogenic substances in religious ceremonies or shamanic rituals. That includes not just ancient Egypt but also ancient Greek, Vedic, Maya, Inca, and Aztec cultures. The Urarina people who live in the Peruvian Amazon Basin still use a psychoactive brew called ayahuasca in their rituals, and Westerners seeking their own brand of enlightenment have also been known to participate.

    For instance, in 2023, David Tanasi, of the University of South Florida, posted a preprint on his preliminary analysis of a ceremonial mug decorated with the head of Bes, a popular deity believed to confer protection on households, especially mothers and children. After collecting sample residues from the vessel, Tanasi applied various techniques—including proteomic and genetic analyses and synchrotron radiation-based Fourier-transform infrared microspectroscopy—to characterize the residues.

      Starwatch: track Cetus, the sea monster, sprawling across the night sky

      news.movim.eu / TheGuardian • 17 November, 2025

    Cetus, also known as the whale, is one of the faint constellations but you have a week to trace its outline

    This week, track down the constellation Cetus, variously referred to as the whale or sea monster. It is one of the faint constellations, but it sprawls across the sky, taking up roughly 1,230 square degrees, which makes it the fourth largest of the 88 modern constellations. Although it lacks bright stars, there is something hypnotic about tracing its faint outline across the sky.

    The chart shows the view looking south-southeast from London on 17 November at 20:00 GMT. However, the view will not change much all week. Since it lies close to the celestial equator, Cetus is visible in northern and southern hemispheres.

      The evolution of rationality: How chimps process conflicting evidence

      news.movim.eu / ArsTechnica • 16 November, 2025

    When Aristotle claimed that humans differ from other animals because they have the ability to be rational, he understood rational to mean that we could form our views and beliefs based on evidence, and that we could reconsider that evidence. “You know—ask ourselves if we should really believe that based on the evidence we’ve got,” says Jan M. Engelmann, an evolutionary anthropologist at the University of California, Berkeley.

    Engelmann says that from the beginning of the Western intellectual tradition, people thought that only humans are rational. So, he designed a study to see if rationality shows up in chimpanzees. It turned out that they’re almost as rational as we are.

    Food puzzles

    “There was quite a bit of research showing that chimpanzees can form their beliefs in response to evidence,” Engelmann says. The experiments usually involved chimpanzees deciding which of the two boxes contained a snack. When the researchers shook both boxes and there was a rattling sound coming from one of them, the chimps almost always chose the box where the rattling came from.
