- 1Physicists Set New Record With Giant Schrödinger's Cat State●Physicists Created a Record-Breaking Schrödinger's Cat With Some of The Weirdest Atoms in Physics
Physicists report creating a record-breaking Schrödinger's cat state using some of the strangest atoms known to physics, pushing quantum superposition to unprecedented scale. The achievement, covered by ScienceAlert, points to progress in controlling quantum states of matter. Researchers say such experiments test the limits of quantum mechanics and could inform future quantum technologies.
- 2AI study at Large Hadron Collider questions existence of 10 dimensions▼10 dimensions may not exist: AI study at Large Hadron Collider challenges theory
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.

Physicist and broadcaster Jim Al-Khalili will present the 2026 Royal Institution Christmas Lectures, tackling the mysteries of time for a family audience. The Lectures, a British institution since 1825, have previously been led by figures such as David Attenborough and Brian Cox, and the announcement has been welcomed by science communicators.

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.
- 5AI Solves Nine-Loop Physics Problem in Challenge▼A Physicist Challenged AI to Solve a Nine-Loop Problem. Claude Did It.
A physicist challenged artificial intelligence to tackle a notoriously difficult nine-loop problem in theoretical physics, and Anthropic's Claude succeeded. The feat has drawn attention because such multi-loop calculations are among the most complex in the field, typically demanding lengthy work by specialists. Researchers are debating what this means for the future of AI-assisted science and whether advanced models can now handle genuinely expert-level mathematical physics.
- 6Quantum simulator captures process that can break quark strings▼Quantum simulator captures a strange process that can break quark strings
Researchers have used a quantum simulator to observe a process capable of breaking quark strings, the bonds that bind quarks together inside particles. The simulation offers a rare window into string-breaking, a phenomenon in quantum chromodynamics that is otherwise impossible to track directly because quarks cannot be isolated. Physicists say such simulators could help probe questions that classical computers cannot handle.
