Hi, AI Tech News - новости ИИ

🤖 AI Models Are So Smart They Can't Pretend to Be Bad Students Researchers at Drexel University tried to make language models act like students with different levels of algebra knowledge. But simply telling them to "answer like a struggling student" wasn't enough to make them play the role convincingly. ✏️ Gemini 3.1 Flash Lite, Claude Haiku 4.5, and GPT-5.4-mini were given 379 algebra problems and assigned five different student personas. Yet they failed at the task: whether the model was an "A student" or a "poor student," its accuracy stayed between 96.8% and 100%. The issue is that the model already knows the correct answer and struggles to suppress its own capabilities. So the authors split the task into two stages: first, a separate algorithm models what a student knows and where they are likely to make mistakes; then, an LLM explains the student's answer. This produced more plausible performance differences: the "near-expert" student scored 85.2% accuracy, the average student 57.8%, and the struggling student 44.1%. 👨 The authors acknowledge that they have not yet compared their virtual "students" with real ones. So for now, this is more a method for teaching AI to make believable mistakes than an accurate model of how humans learn. @hiaimediaen

🤖 The Second World Humanoid Robot Games Have Wrapped Up in Beijing The standout result came from Tiangong Ultra, which ran the 100 meters in 8.64 seconds—0.94 s faster than the world record of Usain Bolt, "the fastest man in the world". For comparison, the best 100 m time at the first Games a year ago was 21.5 s. Tiangong Ultra also broke human records in the 400 m and the 1500 m. The robot ran fully autonomously. ⏫ Many people noticed how much more capable the robots have become in just a year since the first Games. "This year, they are much better. They are like healthy newborn babies growing up," says one spectator. That said, there were plenty of epic failures too. Robots slammed into crash mats at full speed (they still haven't learned to brake from that kind of momentum), collapsed under the weight of their loads, or lost coordination and fell over in ridiculous ways. Some left the arena on stretchers ⤴ 🔄 But there will probably be fewer such mishaps every year—and more broken human records. Whose competitions are more fun to watch? ❤️ — Robots 🔥 — Humans 🤣 — We need humans vs. robots games @hiaimediaen

💡 Scientists Made Cookies From Plastic Bottles, But They Have Not Tried Them Yet Researchers at Southern Illinois University have developed a technology that can turn PET plastic waste and plant waste into food ingredients. 🔥 First, plastic bottles and plant waste are ground up and treated with water and oxygen under high temperature and pressure. The material breaks down into carbon-rich molecules. Specially engineered yeast then converts them into proteins, fats, and organic acids. Next, they add starch, fiber, and a sweetener to the mixture, which they feed into a food-grade 3D printer. This produces small protein cookies called µBites—"microbites." To improve the flavor, the researchers also engineered baker's yeast to produce vanillin from plant waste. ❤️ The scientists praise the aroma, but they have not tasted the cookies themselves yet, they are waiting for university approval. ➡️ µBites were originally created as part of NASA's Deep Space Food Challenge, as a way to produce food during long-duration space missions. While the technology is still far from mass production—a kilogram of these cookies currently costs around $60—the researchers expect the price to fall as the process scales up. Would you try a cookie made from a plastic bottle? ❤️ — Yes, it looks tasty! 🔥 — I already get enough microplastics in my food @hiaimediaen

🎓 Danish Students Will Have to Defend Written Assignments Orally Because of AI Starting this school year, Danish upper secondary school students will have to orally defend the major written SSO assignments they complete at home. The measure was announced by the country’s education minister, Magnus Heunicke. He says action is needed to ensure that AI does not undermine students’ skills, academic abilities and, above all, their ability to think for themselves. Schools will also be encouraged to have students complete more written assignments at school under controlled conditions, so teachers can follow the students’ work process, provide relevant feedback and create a more accurate basis for assessment. 💡 At the same time, Denmark is experimenting with allowing students at selected upper secondary schools to use AI while preparing for an oral English exam. During the preparation period, students may use available tools, including generative AI, but they must then give their oral presentation in person in front of an examiner. ✈ According to the Danish Evaluation Institute, about 90% of upper secondary students already use AI for schoolwork, while two-thirds say they have cheated using AI at least once. Should AI Be Banned in Schools? ❤️ — Yes, AI is replacing teachers 🤔 — Only during exams 🔥 — No, students should be taught how to use AI @hiaimediaen

🎥 AI Cameras Are Watching Babies Startup Nanit sells cameras that continuously monitor a child using AI. The video is sent to a server, where algorithms record when the child wakes up and falls asleep and track breathing, coughs, and other movements. All the data is analyzed and compiled into charts and a daily sleep score. The most expensive bundle costs nearly $500, while a subscription costs an additional $120 to $300 a year. The startup wants to teach the system to monitor speech development, motor skills, and other developmental milestones. Eventually, the cameras could remain in children's bedrooms until they are 10 years old. In the future, teenagers could receive detailed health analytics based on data collected since infancy. 💡 However, doctors are concerned that constant monitoring may increase parents' anxiety and make them trust their own observations less. "What would you do if you didn't have this app that said your baby needs a nap? You'd look at your baby. And see that they look tired," pediatrician Rebecca Diamond explains. Would you install a camera like this for your child? ❤️ — Yes, it would make me feel more at ease 🔥 — No, my child doesn't need to be watched @hiaimediaen

✖️ A Tick Bite Can Cause a Meat Allergy Scientists are reporting the rapid spread worldwide of α-gal syndrome—an unusual food allergy that can develop after bites from certain ticks. During a bite, the carbohydrate α-gal in the parasite's saliva enters the bloodstream and triggers the production of IgE antibodies. As a result, whenever the body comes into contact with the α-gal molecule—which is also found in mammal meat, dairy products, gelatin, and medications containing animal-derived ingredients—the immune system may attack it. Symptoms can include stomach pain, vomiting, hives, swelling, or difficulty breathing. At least two people worldwide have already died as a result of this allergy. ⏳ The syndrome's most unusual feature is the delayed reaction, which can take up to eight hours. Someone may eat a steak in the evening and wake up in the middle of the night with an attack, without connecting it to dinner. Scientists believe that α-gal-containing fat molecules from meat first travel through the intestines and lymphatic system, gradually breaking down into particles that can seep into tissues and trigger an immune response. 🌐 In certain areas of Australia, the syndrome affects more than 700 people per 100,000 residents, and since 2020, the number of suspected cases has been growing by around 22% each year. In the United States, estimates suggest that up to 450,000 people may be affected. The increase in cases has been linked to climate warming, which is expanding tick habitats, as well as to growing deer populations—the main hosts of these parasites. There is currently no cure, but the syndrome is not always chronic. After several years without tick exposure, antibody levels may fall, and some people can gradually reintroduce meat into their diet. @hiaimediaen
