Startup Fluxnium has emerged from stealth with technology, based on U.S. Department of Energy lab research, that extracts uranium from ocean water at costs it claims can compete with traditional mining. The company closed a $7 million seed round led by Congruent Ventures, with backing from Active Impact Investments and Constellation Energy, the largest U.S. nuclear operator.
Fluxnium, a stealth clean-tech startup led by repeat founder Jeff Green, says it has developed technology to economically extract uranium from ocean water, potentially rivaling traditional uranium mines in cost. The company closed a $7 million seed round led by Congruent Ventures, with backing from Active Impact Investments and Constellation Energy, and builds on extraction methods originally developed at U.S. Department of Energy national labs.
A Hacker News poster describes damaging a PS4 controller board while trying to fix a joystick through desoldering and resoldering, leaving the controller non-functional. Despite following common safety and technique advice like ventilation, proper iron tips, and flux use, they are asking the community for reliable learning resources to improve their soldering skills and avoid further mistakes.
A self-taught hobbyist attempting to repair joystick modules on PlayStation 4 controllers damaged a circuit board during the process, leaving the controller non-functional after desoldering and resoldering work. The person is already using recommended practices like ventilation, flux, and proper iron tips, but is asking the community for reliable resources to improve their soldering skills and avoid further mistakes.
Researchers compiled river chemistry data from basaltic watersheds worldwide to recalculate how much carbon dioxide is naturally absorbed through silicate rock weathering. They found that critical zone processes—such as atmospheric deposition, hydrothermal contamination and secondary mineral formation—reduce the alkalinity that actually reaches rivers, meaning basalt weathering contributes a smaller share of global CO2 drawdown than prior estimates suggested, roughly 0.3% of annual anthropogenic emissions.
Billie Piper, known for playing companion Rose Tyler, was asked again about her connection to Doctor Who but gave no clear answers about her role going forward. The franchise itself remains in an uncertain state, with its future direction not yet settled by the BBC or its producers.
A newsletter roundup from Wonder Tools highlights two visual creation tools: Whorl, which lets users build animated 3D graphics without technical expertise, and Flux 3, which generates polished AI video clips from text prompts or images. Both are positioned as accessible options for producing eye-catching visual content.
