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.

Reports say the disconnection of the Large Hadron Collider has begun, marking the start of a shutdown phase for the world's largest particle accelerator at CERN near Geneva. The machine, famous for discovering the Higgs boson in 2012, is periodically switched off for maintenance and upgrades between experimental runs. Readers and physicists are following news of the work, with attention on what upgrades could mean for future discoveries.

Researchers report that they have determined a key measurement relating to the early universe with record-breaking precision. The result is described as the most accurate of its kind, though the specific quantity measured and the team behind it have not been detailed. More precise early-universe measurements help scientists test models of the cosmos's first moments and constrain theories of how the universe evolved.

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.

Security publication BankInfoSecurity is asking whether organizations' networks are prepared for post-quantum cryptography, the shift to encryption methods that can withstand attacks from future quantum computers. The discussion comes as regulators and standards bodies push industries to begin migrating away from currently used public-key encryption before quantum capabilities make it vulnerable.

Poland's National Centre for Nuclear Research (NCBJ) is leading a study of neutrino scattering at the Large Hadron Collider at CERN. The work aims to measure how neutrinos interact with matter at the highest energies ever achieved, a poorly tested area of particle physics. The findings could sharpen understanding of the weak nuclear force and improve measurements of other LHC results.

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.

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.

Quanta Magazine reports that while quantum effects in biology remain unproven, the mathematics used to model biological systems increasingly resembles quantum formalism. Researchers are applying quantum-like mathematical frameworks to describe how living systems behave, bridging physics and biology without claiming organisms actually exploit quantum mechanics. The piece is drawing attention on tech and science discussion forums, where readers are debating whether these tools reveal deep parallels or are just convenient analogies.

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.

Reports describe a single photon that traveled roughly 2 billion light-years before reaching Earth, a journey that current physics supposedly says should not have been possible. The claim is circulating widely, but no specific observatory, source event, or research team has been named, so the finding's details and significance remain unverified.

Mobile Industry Review has published an opinion piece asking whether the telecoms industry was wrong in its bets on millimeter wave technology for 5G.
