An AI model cracks an 87-year maths problem; landfills leak far more methane than thought; Canada's fires get a formal climate attribution.
A mathematician at Anthropic used Claude Fable 5 to find a simple counterexample to the Jacobian conjecture, a problem in algebraic geometry that has resisted resolution since 1939. The result is posted to arXiv and under peer review.
A Canadian fossil site contains creatures from 567 million years ago showing evidence of movement, sexual reproduction, and tissue differentiation — pushing the confirmed origin of complex animal life back by tens of millions of years.
Researchers developed a catalyst that converts carbon dioxide into a high-value industrial chemical at room temperature with record efficiency, eliminating the energy-intensive heating steps that make most CO₂ utilization processes uneconomical.
A long-term monitoring study found that methane emissions from landfills are substantially above what standard estimation methods indicate. Methane traps roughly 80 times more heat than CO₂ over a 20-year window.
A rapid attribution study concludes human-caused climate change roughly doubled the probability of the extreme heat and drought conditions driving this summer's record Canadian wildfires — findings that directly contradict the Trump administration's forest-management framing.
A SpaceX rocket that launched lunar landers and then drifted off course for over a year struck the moon Wednesday, as trajectory models had predicted. Ground-based telescope observations confirmed the impact.
Georgia Tech researchers found that nanowire scaffolds can restore the signaling and proliferation capacity of aged T cells in a laboratory setting, reversing functional losses associated with immune aging without genetic modification.
