The physics of AI hallucination: New research reveals the tipping point for large language models
Physicist Neil Johnson has mapped the exact moment AI can flip from accurate to false, and he says understanding the physics could be the key to safer systems.
AI enters the scientific loop: Simulation, integrity, and the rise of open reasoning
From prompt injection to physics simulators and open reasoning models, recent news shows that AI isn’t just accelerating science, it’s reshaping how it works. The question now, is will it deepen inquiry, or erode the principles on which credibility in science is built?
Peer review in the age of AI: When scientific judgement meets prompt injection
Hidden prompts buried in preprints show how easily large language models (LLMs) can be manipulated, exposing a deep vulnerability in science’s quality-control system. As artificial intelligence (AI) becomes part of the scientific review process, traceability and transparency must become new norms, not afterthoughts.
AI faces a tough physics exam: New benchmark reveals the challenge
Large language models have advanced dramatically in recent years, yet when physicists gave them an undergraduate-level test, even the best models were only correct on around one out of every three questions. The new PhysUniBench benchmark exposes how far AI still has to go in mastering fundamental science.
How string theory lost its strings
String theory was once hailed as the “theory of everything” — a unified model of nature built on tiny vibrating strings. But after decades of expansion, the field has evolved beyond its namesake, embracing branes, dualities, and abstract geometry. Some physicists now wonder: is it time to rename the theory entirely?
Engineering the implausible? Paper explores stable Dyson spheres and ringworlds
Artificial structures surrounding an entire star were thought to be impossible. A new calculation shows that they could be supported by the gravity of a second star.
New study reexamines time symmetry in quantum systems
New research suggests time symmetry in quantum systems, offering new perspectives and reigniting ongoing debates.
Unlocking the quantum code: Physicists map the statistics of entanglement
A new study maps all quantum correlations in the minimal Bell scenario, advancing our understanding of entanglement.
D-Wave’s quantum computing milestone: Supremacy or simply progress?
D-Wave claims quantum supremacy, but the physics community remains divided on its definition.
Gravity from entropy: New theory bridging quantum mechanics and relativity
Ginestra Bianconi proposes that gravity emerges from quantum information entropy in new study.
Open Quantum Design seeks to democratize quantum computing
Offering full-stack open access to its trapped-ion quantum computer, Open Quantum Design and its partners aim to push the field forward.
What more can we expect from the James Webb Space Telescope?
Two years after JWST's launch, it has rewritten the cosmic history books – and the best is yet to come.
