Microplastics Could Be Weakening Your Bones, Research Suggests

3 weeks 4 days ago
A review of 62 scientific studies published in Osteoporosis International found that microplastics weaken bones by disrupting bone marrow stem cells and stimulating osteoclasts, cells that degrade bone tissue. Laboratory experiments found the particles reduce cell viability, induce premature cellular aging, modify gene expression, and trigger inflammatory responses. Animal studies found microplastic accumulation decreases white blood cell counts and deteriorates bone microstructure, creating irregular cell structures that increase fracture risk. Rodrigo Bueno de Oliveira from the State University of Campinas in Brazil said the effects interrupted skeletal growth in test animals.

New Claude Model Runs 30-Hour Marathon To Create 11,000-Line Slack Clone

3 weeks 4 days ago
Anthropic's Claude Sonnet 4.5 ran autonomously for 30 hours to build a chat application similar to Slack or Teams, generating approximately 11,000 lines of code before stopping upon task completion. The model, announced today, marks a significant leap from the company's Opus 4 model, which ran for seven hours in May. Claude Sonnet 4.5 performs three times better at browser navigation and computer use than Anthropic's October technology. Beta-tester Canva deployed the model for complex engineering tasks in its codebase and product features. Anthropic paired the release with virtual machines, memory, context management, and multi-agent support tools, enabling developers to build their own AI agents using the same building blocks that power Claude Code.
