Researchers have developed a way to reshape light so it can control magnetic memory and alter a material's magnetic properties. The advance could open new paths for data storage technology, allowing magnetism to be manipulated optically rather than only through magnetic or electrical means. Details of the mechanism and which institutions were involved remain sparse.

A study using artificial intelligence at the Large Hadron Collider challenges the theory that the universe has ten dimensions. The AI analysis of particle collision data casts doubt on predictions from string theory, which requires extra spatial dimensions beyond the four we observe. If confirmed, the findings would force physicists to rethink one of the leading candidate frameworks for unifying quantum mechanics and gravity.

A physicist reports that he challenged an AI system to tackle a nine-loop problem, a famously demanding calculation in theoretical physics, and that Anthropic's Claude was able to solve it. The claim is drawing attention from researchers debating how capable large language models really are at advanced mathematics and physics, and what this means for the future of scientific work.

The Large Hadron Collider at CERN has begun its shutdown, or disconnection, marking the start of a planned pause in operations of the world's largest particle accelerator. The process involves powering down and decommissioning key systems. The shutdown is expected to allow upgrades that will boost the collider's luminosity for future physics runs, though no detailed timeline was given.

Researchers report that a quantum simulator has captured a strange process capable of breaking quark strings, the bonds that hold quarks together inside particles. The experiment offers a way to observe string-breaking, a phenomenon in quantum chromodynamics that is otherwise out of reach for classical computers and conventional particle accelerators. Physicists say such simulations could deepen understanding of how matter behaves under extreme conditions.

Scientists are highlighting a proposal to use particle accelerators to transmute long-lived radioactive waste from nuclear energy, potentially reducing its hazardous lifespan from around 100,000 years to just a few centuries. The idea, known as accelerator-driven transmutation, is being discussed as a way to ease one of nuclear power's biggest drawbacks: the need to store spent fuel safely for many millennia.

The National Centre for Nuclear Research (NCBJ) is leading a study of neutrino scattering at the Large Hadron Collider. The work examines how neutrinos interact with matter at the highest collision energies available, a regime previously inaccessible to dedicated neutrino experiments. Researchers say the findings could sharpen understanding of the weak force and improve modelling of particle collisions at CERN's flagship accelerator.

Security publication BankInfoSecurity is asking whether organizations' networks are prepared for the transition to post-quantum cryptography, the new encryption standards designed to withstand attacks from future quantum computers. The piece underscores growing pressure on enterprises and governments to inventory cryptographic systems and begin migrating before quantum-capable threats materialize.

Education experts are cautioning that students may be leaning too heavily on artificial intelligence tools, raising concerns about weakened critical thinking, reduced writing skills, and academic integrity. The warning, reported by Gulf Times, adds to a growing debate among teachers and researchers worldwide about how AI should be used in classrooms and how schools can balance its benefits with the risks to genuine learning.

Physicists report new evidence that gravity can collapse the dimensions of space, supporting the idea that gravity is holographic — that the universe's three-dimensional structure may be encoded on a lower-dimensional surface. Researchers stress the implications are not yet understood, and what this means for the nature of reality remains an open question driving discussion among cosmologists and science commentators.

Researchers at the International Center for Nanoarchitectonics report guiding quantum vortices using purpose-built atomic-scale rails, a technique that could give scientists precise control over superfluid and superconducting behavior at the nanoscale. The work is drawing attention in physics circles for its potential implications for quantum materials research and future quantum technologies.

Mobile Industry Review has published an opinion piece asking whether the telecoms industry was wrong in its bets on millimeter wave technology for 5G. The article weighs mmWave's promised ultra-fast speeds against its limited range and spotty real-world deployment, reigniting debate over whether operators overinvested in the high-band spectrum at the expense of more practical mid-band rollout.

Thales, Bull and the French Alternative Energies and Atomic Energy Commission (CEA) are working on quantum computing software for the French armed forces, according to a report by Clubic. The cooperation combines the industrial and research expertise of the three organisations to advance quantum technologies with potential defence applications. The story is circulating among French-speaking tech and science observers.

Technology leaders are being urged to begin migrating corporate systems to post-quantum cryptography, encryption methods designed to withstand attacks from future quantum computers. The argument is that quantum advances could eventually break today's standard encryption, and that organisations which delay the transition risk exposing sensitive data. CIOs are advised to inventory cryptographic assets and plan upgrades now.

Sebastian Hassinger, host of The New Quantum Era podcast, argues that neutral-atom platforms currently hold the lead among quantum computing qubit technologies. He points to the approach's combination of scalability, long coherence times and flexible connectivity as reasons it is outpacing rival architectures such as superconducting and trapped-ion systems, at least for now.

The 2011 tsunami in Japan is reported to have led to the creation of hybrid fish, but these hybrids almost completely disappeared in the years afterwards. The claim highlights how the disaster's environmental disruption briefly allowed crossbreeding between fish populations before natural conditions closed that window again.

The European Union's Galileo satellite navigation system includes an encrypted signal service that can be used to counter GPS spoofing, where attackers broadcast fake positioning data to deceive receivers. Coverage is examining how the system's authentication features let devices verify that navigation signals genuinely come from Galileo satellites, a capability drawing interest as spoofing incidents around conflict zones and near critical infrastructure raise concerns about the vulnerability of civilian navigation systems worldwide.

Brazil's CNPEM research centre and CERN are working together on magnet technology for a proposed 91-kilometre particle collider. The collaboration ties Brazilian scientific institutions into CERN's long-term plans for next-generation accelerator hardware, an area where magnet performance is a core technical challenge. The partnership highlights growing international participation in future collider projects.

The Governor of Gujarat has called on young researchers to examine physics, mathematics and astronomy through a logical lens. The appeal, reported by ThePrint, frames rigorous reasoning as central to scientific study, and comes amid ongoing public discussions in India about strengthening research culture and scientific temper among students and early-career academics.

An AI system has reportedly set a record by independently computing a 9-loop physics amplitude, a Feynman diagram calculation far beyond typical human work. Most real-world perturbative calculations in quantum field theory stop at 2 or 3 loops due to their complexity. The result highlights how machine learning is beginning to automate some of the most demanding mathematical tasks in theoretical physics.

Austrian cooling specialist Noctua says it wants to adapt server-grade cooling capable of handling 2000W thermal loads for desktop computers. The move targets next-generation CPUs and GPUs whose power draw keeps climbing, as consumer hardware increasingly borrows thermal solutions once reserved for data centers. PC enthusiasts are watching closely to see what form the design will take.
