For more than six decades, local scientists have collected sugar maple leaves from Gatineau Park to measure their radiocarbon levels, creating the longest continuous record of its kind. Now, a study of those leaves led by the André E. Lalonde National Facility for Accelerator Mass Spectrometry (AEL-AMS) located at the University of Ottawa shows that the effects of Cold War–era nuclear weapons testing have only recently disappeared from the local biosphere. The study, titled “Stored carbohydrates buffer Bomb and Suess radiocarbon effects in maple leaves across a 65-year Ottawa region record,” was published in Scientific Reports.

Researchers at the University of Rochester and Technion–Israel Institute of Technology accidentally discovered a new way to rearrange the internal structure of molybdenum—an extremely heat-resistant metal—at room temperature. Molybdenum is typically used to reinforce nuclear reactors, jet engine turbine blades and rocket nozzles because it doesn’t melt until it is heated to more than 2,600°C (4,712°F). Controlling its atomic structure at room temperature could open the door to more applications, including next-generation semiconductors.

Scientists are exploring how iron powder could transform renewable energy storage and transportation while giving aging coal power plants a new purpose. Iron powder could help transform old coal power plants into a source of climate-neutral electricity, according to a new study from the Karlsruhe Institute of Technology (KIT). Researchers found that this recyclable fuel […]

Anthropic just released Claude Fable 5.2 and Claude Mythos 5.2, and while it is easily the most capable public model in the world across long-horizon coding, robotics, hardware design, and theoretical physics, the biggest story is buried in the fine print. For the first time, Anthropic admits it deliberately limited Fable 5.2 during training on accelerator kernel optimization and LLM architecture research so those specific skills stay capped at Opus 5.5 levels. We break down how today’s release confirms Fable 5.2 is METR’s Model 3, why the unreleased Model 4 and Anthropic’s secret NanoGPT-style autonomous experiment scaffold are grazing the…
