New research reported by ScienceDaily suggests that the length of Earth's day is not precisely 24 hours, and that the cause may be found deep within the planet's interior. The finding is drawing attention for what it implies about Earth's inner structure and the slow physical processes that shape how the planet rotates over time.

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.

Union Minister Ashwini Vaishnaw has warned that India's semiconductor ambitions will face cyberattacks, fake news campaigns and even physical attacks as the country expands its chip manufacturing push. Citing past incidents during Apple's rollout in India, including cut power lines and deliberate food poisoning of workers, he said sabotage attempts should be expected and that the government is prepared to counter them.

A Harvard study reports that students using an AI tutor to learn physics achieved better results than peers in standard active-learning classes. The findings suggest personalized, conversational AI instruction can outperform established classroom methods, sparking debate among educators about how such tools should fit into teaching and whether AI could reshape how universities deliver science education.

Big Tech companies are reportedly assessing physical security risks tied to the escalating conflict with Iran, with the Strait of Hormuz identified as the center of the crisis. The situation is having an immediate impact on global markets and raising concerns about energy supplies, adding infrastructure and personnel risks to the industry's war-related worries.

A new study reports that people with internet addiction show signs of exhausted physiological stress systems, suggesting chronic online overuse may wear down the body's stress response. The findings add to growing concern about excessive internet use and its physical, not just psychological, health effects.

A Harvard study has concluded that an AI tutor outperformed traditional in-class physics teaching. The findings suggest students using the AI tutor achieved better learning outcomes than those in conventional classroom settings. The result is drawing attention as educators debate the role of artificial intelligence in higher education and whether such tools should be adopted more widely in science courses.

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.

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.

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.

A new Brookings Institution study examines the enormous physical footprint of the AI boom, from specialized chips and electricity demand to purpose-built data centers, noting that two-thirds of a data center's cost can go into hardware and construction. The report assesses how large the buildout has become and what financial and economic risks it may pose if AI investment slows or falls short of expectations.

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.

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.

At least a dozen Chinese banks plan to wind down their retail leveraged precious-metals trading services, according to a widely shared report. The move restricts retail investors' access to leveraged gold and silver products at a time when demand for physical precious metals in China is described as surging.

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.

New research presented via EurekAlert describes how artificial intelligence paired with physics-based methods is advancing imaging techniques, including work that makes the invisible visible and automates the colorization of anime footage. The announcement highlights computational imaging as a growing field where machine learning and physical modeling intersect, with potential applications in science and animation production.

New research suggests magnetic fields may have played a key role in the formation of the solar system, potentially influencing how material in the early solar nebula collapsed and clumped into the sun and planets. The finding adds to ongoing debate among scientists about the physical processes that set planetary formation in motion more than 4.5 billion years ago.

Ukraine's cybersecurity leadership, represented by Koretskyy, has described measures the country is taking to protect its internet infrastructure against ongoing Russian cyberattacks. The remarks detail defensive preparations as Ukraine continues to face digital threats alongside the physical war, highlighting how critical networks and services are being shielded from disruption.

The Pentagon is asking for $30.3 million over five years to develop an AI-powered lie detection system that can analyze body language remotely, without physical contact. The program, called Polygraph Next, is included in the Defense Counterintelligence and Security Agency's 2027 budget request. Commenters are raising concerns about the privacy implications and scientific reliability of automated deception detection, noting that traditional polygraph accuracy is already contested.

Consultancy Bain & Company says artificial intelligence is reshaping retail in ways that will push underperforming stores out of the market. The firm argues retailers that fail to adopt AI-driven operations, pricing and customer insights risk losing ground to more efficient competitors, accelerating store closures across the sector.
