- 1Physicists Create Record-Breaking Quantum 'Schrödinger's Cat' State▼Physicists Created a Record-Breaking Schrödinger's Cat With Some of The Weirdest Atoms in Physics
Physicists report creating the largest-ever Schrödinger's cat state, putting unusually heavy atoms into a quantum superposition where they effectively exist in two states at once. The record-breaking experiment pushes the boundary of how massive an object can be while still showing quantum behavior, a question that has challenged physicists for decades 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 is challenging the theory that the universe may contain ten dimensions. Researchers applied machine learning methods to collider data to test predictions tied to string theory, and the results reportedly cast doubt on whether the extra dimensions theorised by physicists actually exist, prompting debate in the physics community.
- 3Ultra-Intense Light Fails to Speed Up Water Evaporation▼Scientists Blasted Water With Light 10 Billion Times Brighter Than Sunlight. It Still Didn't Evaporate Faster.
Researchers subjected water to light roughly 10 billion times brighter than sunlight, expecting faster evaporation, but the water did not evaporate any quicker. The surprising null result challenges assumptions about how extremely intense light interacts with liquid water, and is drawing attention from physicists curious about what limits evaporation under such extreme conditions.

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.
- 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.
- 7AI 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.
