AI’s Influence on Education and Industry

An OECD report released this week found that students who use artificial intelligence for schoolwork tend to score lower in science than peers who do not, based on data from more than 760 000 learners in 91 countries. The analysis shows the negative effect is strongest when AI is used to summarize texts or draft assignments, while modest, purpose‑driven use for preliminary research is linked to a smaller decline. The finding matters because it raises questions about how AI tools are integrated into classrooms and whether current practices support or hinder the development of problem‑solving skills.

Technology and media leaders stressed clearer communication about AI’s benefits and risks. CoreWeave chief Mike Intrator told CNBC that AI firms have not adequately explained how data‑center‑driven advances help families, warning that the pace of change feels frightening. Visa chief Ryan McInerney said consumer trust in agentic payment systems remains low and grows slowly. In broadband, Comcast CFO Jason Armstrong linked subscriber losses to fixed‑wireless and satellite rivals, saying the company is adjusting prices and mobile offers. Disney CFO Hugh Johnston said the studio is testing a free, ad‑supported streaming tier to retain viewers who might otherwise cancel paid subscriptions.

A study of 485 Swedish high school students found that iron deficiency was not the main cause of fatigue among teenage girls. Researchers from Lund University reported that neither anemia nor low ferritin levels were directly tied to higher fatigue or lower quality of life. Instead, heavy menstrual periods were strongly linked to exhaustion and reduced wellbeing, even after accounting for iron stores. The authors suggested menstrual pain, sleep disruption, or social withdrawal as possible drivers. They also noted that skipping meals and daily nicotine use were associated with greater fatigue. The team said future work will aim to improve screening tools and develop better treatments.

The day’s other news spanned disparate fields. Scientists used Jurassic fossils and AI‑assisted modeling to recreate the chirps of nine grasshopper species, revealing ultrasonic calls that predate the first known bats. Formula 1 announced a debut at the new Madring street circuit in Madrid. At the Venice Film Festival, the film “Company” premiered in competition. In hockey, Alex DeBrincat said he intends to re‑sign with the Detroit Red Wings, noting he values playing alongside teammates and that the club will settle his contract, negotiate a deal for a defenseman and address Larkin’s trade request. Looking ahead, the digests point to Disney’s test of a free ad‑supported streaming tier, broadband strategies, the OECD’s suggestion that moderate, intentional AI use can benefit learners when students learn to critique AI‑generated content, Lund University’s fatigue screening work, Formula 1’s agreement keeping Madrid on the calendar through 2035, and Red Wings contract talks and GM search.

AI Blowback, Broadband Struggles, Disney's Free Streaming Plan

CoreWeave CEO Mike Intrator told CNBC that AI companies have not adequately explained the benefits of their data‑center‑driven technology to the public. Intrator said the rapid pace of change is frightening for individuals and their families, and that the industry must better communicate how AI can help society. Visa chief executive Ryan McInerney added that consumers remain skeptical of agentic AI platforms that can make payments on their behalf, and that trust is growing slowly. Meanwhile, Comcast CFO Jason Armstrong warned that broadband customer losses are driven by fixed‑wireless and potential satellite competition, and that the company is adjusting pricing and mobile strategies. Charter Communications CEO Chris Winfrey said the company is confident that long‑term broadband demand will improve, despite short‑term competitive pressure. Disney CFO Hugh Johnston revealed the studio is testing a free, ad‑supported streaming tier to retain customers who might otherwise cancel paid subscriptions. The free tier would allow Disney to keep a foothold in the market while investing in original content for its paid service. These remarks illustrate how tech and media leaders are grappling with AI backlash, broadband disruption, and shifting streaming models in a rapidly evolving landscape.

Heavy periods and lifestyle drive teenage fatigue

A study of 485 Swedish high school students has challenged the common assumption that iron deficiency is the primary cause of fatigue in teenage girls. Researchers from Lund University found that neither anaemia nor low ferritin levels were directly associated with higher fatigue or lower quality of life among the participants. Instead, the data revealed that heavy menstrual periods were strongly linked to increased exhaustion and diminished wellbeing, even when accounting for iron levels. The study suggests that factors such as menstrual pain, sleep disruption, or social withdrawal may be the actual drivers of fatigue rather than a lack of iron. Other lifestyle factors also played a significant role, as skipping meals and daily nicotine use were both associated with greater fatigue. Researchers noted that while iron deficiency remains a global health concern, focusing solely on it may cause clinicians to overlook these other modifiable lifestyle elements. Future research will focus on developing better screening tools to identify true iron deficiency and more effective treatment strategies for this demographic.

Scientists Recreate 165‑Million‑Year‑Old Jurassic Insect Chirps

Scientists from the University of Graz, Lincoln, Bristol, Beijing, and Tempe have used fossils from Inner Mongolia to recreate the chirps of nine Jurassic grasshopper species. The study, published in the journal PNAS, analyzed the wing‑ridge structures that produced stridulations, allowing researchers to estimate the pitch and rhythm of the insects' calls. By combining fossil morphology with AI‑assisted simulations, the team generated audio files that show frequencies ranging from low, cricket‑like tones to high, leafhopper‑like sounds. Remarkably, one species, Sigmaboilus peregrinus, produced ultrasonic calls between 20 and 22 kilohertz - well above human hearing and predating the first known bats. This finding challenges the idea that high‑frequency insect sounds evolved solely to evade bat predation and suggests alternative drivers such as predator avoidance or mating strategies. The reconstruction demonstrates that the Jurassic period had a far richer and more diverse acoustic landscape than previously understood. The work also marks the oldest known reproduction of animal sound, providing a new window into prehistoric ecosystems.

AI use linked to lower student test scores

A recent OECD educational report reveals that students using artificial intelligence for schoolwork generally perform worse in science than those who do not. The Programme for International Student Assessment (PISA) study, which analyzed data from 760,000 students across 91 countries, indicates that the impact of AI depends heavily on how the technology is applied. Students who use AI for tasks like summarizing texts or drafting assignments tend to see lower academic results. Conversely, those who use the tools for preliminary research or general learning purposes show a smaller decline in performance. Interestingly, the data suggests that moderate, intentional use can actually benefit learners, particularly when they are taught to critically evaluate the accuracy of AI-generated content. OECD director Andreas Schleicher noted that learning requires a productive cognitive struggle that technology can either enhance or undermine. The report also highlighted a digital divide, noting that AI use is more prevalent among students from advantaged backgrounds. While daily AI users showed higher levels of curiosity, this trait has not yet translated into improved academic grades.

New Madring Street Circuit Set for Formula 1 Debut

Formula 1 is preparing to debut at the brand-new Madring street circuit as Madrid takes over hosting duties for the Spanish Grand Prix from Barcelona. The 3.365-mile layout features up to 24 corners, relentless directional changes, and minimal straightaways. Competitors anticipate a grueling trial, with junior drivers comparing the fast, enclosed layout to an intensified version of Saudi Arabia's Jeddah Corniche Circuit. Key challenges along the lap include a narrow Turn 5 chicane where two cars cannot fit side by side and Turn 12, an aggressive 180-degree banked corner dubbed La Monumental. The banked turn boasts a 24 percent gradient, forcing drivers to endure extreme lateral forces while remaining flat on the accelerator. Carlos Sainz, who helped design safety elements for the turn, warned that tight barriers make the venue one of the toughest additions to modern motorsport. Earlier Formula 3 testing produced 19 red flags across two days, sparking expectations among drivers that the race weekend could see frequent stoppages and safety cars. Ferrari teammates Charles Leclerc and Lewis Hamilton previously evaluated the circuit during filming runs, noting low initial grip and scarce overtaking opportunities. Madrid is contracted to stage the annual grand prix through at least 2035.
