- MathematicsAn AI Mathematical Proof Just Disproved an 80-Year-Old Erdős Conjecture Last October, OpenAI overclaimed an Erdős breakthrough and got publicly dismantled by Thomas Bloom. This week, the same skeptics published companion remarks backing a new AI mathematical proof that disproves a 1946 Erdős conjecture in discrete geometry.
- QuantumThe Quantum Computing Replication Crisis No One Is Talking About A Pittsburgh-led team carefully reran the experiments behind several headline quantum computing breakthroughs and found the signals had simpler, less exotic explanations. The replication paper took a record two years to get published. Here's what it actually changes.
- QuantumPhysicists Hit Rewind on Time — Inside a Quantum Computer A team of physicists ran a quantum computer's clock backwards, nudging scattered particles back into order. They didn't break causality — what they actually did is stranger, and more useful.
- ConsciousnessTwo Big Theories of Consciousness Fought in Public. Nobody Knocked Out. Rival camps usually snipe at each other from a distance. This time, two leading theories of consciousness agreed in advance on exactly which experiment would prove one of them wrong. Then they ran it.
- MathematicsAn AI Just Scored Silver at the Hardest Math Exam on Earth The International Math Olympiad breaks brilliant teenagers. An AI system sat the same problems, worked some for days, and landed one point shy of gold — a line nobody expected machines to cross this soon.
- Quantum FactThe Sun Shouldn't Be Able to Shine By the strict rules of classical physics, the core of the Sun isn't hot enough for hydrogen to fuse. The Sun shines anyway — thanks to a quantum loophole called tunnelling.
