Roughly 85% of the matter in the universe has never been directly detected, as it does not interact with standard instruments. UCLA astrophysicist Alvine Kamaha and the LUX-ZEPLIN collaboration are working nearly a mile (1.6 km) underground in South Dakota, tracking rare particle interactions in an effort to identify dark matter and shed light on one of physics' biggest open questions.

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.

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.

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.

Researchers at Children's National Hospital report that children with chronic kidney disease (CKD) experience declines in cardiopulmonary fitness early in the course of their illness. The findings suggest reduced exercise capacity may develop well before advanced kidney disease, highlighting the value of early monitoring and physical activity interventions for affected children.

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.

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.

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.

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.

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 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.

Researchers at a particle collider have reported a surprising result in experiments involving primordial matter—the hot, dense state thought to have filled the early universe, recreated in collisions inside the machine. The finding, covered by Scientific American, is drawing attention from physicists and science readers, who are discussing what it could reveal about the fundamental behaviour of matter shortly after the Big Bang.

Ukraine's cybersecurity leadership, represented by Koretskyy, has described measures the country is taking to protect its internet infrastructure against ongoing Russian cyberattacks.

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.
