A large global study has examined how screen time affects children's wellbeing, according to reporting carried by Yahoo News New Zealand. The findings address an ongoing debate among parents, educators and health researchers over how digital device use shapes children's mental and physical health. Details of the study's size, methodology and conclusions were not included in the available report.

A Harvard study found that students using an AI tutor learned more physics in less time than peers in traditional classroom lessons. The research compared active learning methods with an AI-driven tutor and reported better results and higher engagement for the AI group. Educators are debating what this means for the future of teaching and the role of lecturers.

Physicists at the University of Illinois Chicago report detecting a ripple dating back to the universe's earliest moments, according to a university news release. The announcement suggests a signal connected to the first instants after the Big Bang, though details of the measurement and its significance remain sparse. The finding, if confirmed, would offer a rare window into the primordial universe and is drawing attention in physics circles.

A new study reports that people with internet addiction show signs of exhausted physiological stress systems, suggesting heavy compulsive internet use may wear down the body's stress response. The finding is drawing attention among health researchers and commentators, who say it adds biological evidence to concerns about excessive screen and online use affecting physical health, not just behaviour or mood.

Researchers at Children's National report that children with chronic kidney disease experience declines in cardiopulmonary fitness at an early stage of the disease. The finding suggests reduced exercise capacity may develop well before advanced kidney dysfunction, highlighting the value of monitoring physical fitness and encouraging safe physical activity in young patients with CKD.

A Harvard study reportedly found that an AI tutor outperformed traditional in-class teaching in physics. According to the report, students learning physics with an AI tutor achieved better results than those taught through standard classroom instruction. The finding is being circulated as fresh evidence that artificial intelligence tools can match or exceed conventional teaching methods in science education, fueling debate about the future role of AI in universities and schools.

Sacramento Kings guard Ben Simmons has spoken publicly about his critics and his mental health, stating that he is now in top form. Simmons, whose career has been marked by high-profile criticism and extended absences from the game, opened up about the toll of the scrutiny and his efforts to recover physically and mentally ahead of his stint with the Kings.

Apple Music is set to open a concert venue inside London's Battersea Power Station, adding a live music space to the landmark's growing retail and entertainment district. The move signals Apple's continued investment in music beyond streaming, following its radio stations and live sessions. Details on capacity, opening date and programming have not yet been confirmed.

New research suggests magnetism played a role in the formation of the solar system, potentially influencing how the early cloud of gas and dust collapsed into the sun and planets. The finding adds to debate over what physical forces shaped our cosmic beginnings, and scientists say magnetic fields could help explain the solar system's original structure.

Theoretical physicists, encouraged by recent progress in understanding black holes, are now applying the same tools to entire universes. Writing for Quanta, physicist Matt von Hippel explains how what they are finding is leading researchers to question fundamental assumptions about physics and cosmology.

Researchers led by Dr. Jona Kayser at MPZPM report that physical processes in dense cell populations strongly influence the best timing of treatment cycles, with implications for both cancer therapy and antibiotics. Treatment resistance remains one of the central challenges in medicine, and the findings suggest that timing could be adjusted based on how tightly cells pack together rather than on biology alone. The work points to new ways of scheduling therapies to delay or avoid resistance.

Commentary in financial media argues quantum computing has reached a turning point, moving beyond the 'physics experiment' stage toward commercial-scale engineering. The focus is shifting from lab breakthroughs to supply chains and manufacturing capability as the decisive factors for which companies succeed in bringing quantum hardware to market. The analysis suggests investors and industry watchers should track production capacity and component suppliers rather than pure research milestones.

Researchers report that tracking heavy water isotopes can sharpen the accuracy of weather forecasts. According to Physics World, measurements of these heavier forms of water provide additional information that improves how well predictions match real conditions. The finding suggests isotope data could become a useful tool in meteorology, though details of the underlying study and its practical deployment are not given.

A Quanta Magazine article explaining the holographic principle in physics is being discussed on Hacker News. The idea is that gravity in a volume of space can be described by information encoded on that volume's boundary, as in the AdS/CFT correspondence, suggesting three-dimensional reality may emerge from lower-dimensional information. Commenters on the post are debating what this implies about the fundamental nature of space, time and whether reality is a projection.

A researcher at the University of Central Florida reports experimental evidence of a new type of magnetism, according to a news release. The discovery could expand scientific understanding of magnetic materials beyond known categories such as ferromagnetism and antiferromagnetism. Details of the underlying mechanism and potential technological applications have not been widely reported yet.

New reporting highlights that people who survived cancer in childhood face a significantly elevated risk of serious mental health difficulties in adulthood, including depression, anxiety and other psychiatric conditions. The findings point to long-term psychological effects of early cancer diagnosis and treatment, and renew calls for survivors to receive sustained mental health monitoring and support, not just physical follow-up care, well into their adult lives.

SiMa.ai, a chip developer focused on physical AI, has reached a valuation of $1.45 billion. The company builds semiconductor technology designed to bring AI processing to physical systems such as machines and edge devices. The valuation places it among the more prominent independent AI chip startups, in a sector drawing intense investor interest as companies race to supply hardware for artificial intelligence beyond data centers.

Chinese AI firm SenseTime has launched SenseMart OS, an operating system designed to bring embodied intelligence into retail environments. The system is aimed at powering robots and smart devices that can perceive, interact with, and assist customers in stores. Details about pricing, availability, and retail partners have not yet been widely reported.

Researchers are combining artificial intelligence with physics-based imaging methods to reveal details invisible to conventional cameras and to colorize anime footage. In a Q&A discussion, experts explain how these techniques could change fields ranging from scientific imaging to animation production, highlighting the growing role of machine learning alongside physical modeling in visual technology.

A new gravity experiment is prompting physicists and science commentators to revisit one of Einstein's core assumptions: that the speed of light is constant. Reports suggest the experiment's findings raise questions about how light behaves under gravitational conditions, challenging textbook relativity. Scientists urge caution, noting that extraordinary claims about relativity require extraordinary confirmation.
