Sakana AI released two image generation models trained on Japanese ukiyo-e artwork: Evo-Ukiyoe generates ukiyo-e-style images from Japanese text prompts, while Evo-Nishikie colorizes monochrome classical woodblock prints into multi-color versions. The models were trained on 24,038 high-quality digitized ukiyo-e images from Ritsumeikan University's Art Research Center, using LoRA fine-tuning and ControlNet techniques. Both models are now publicly available on HuggingFace for research and education, enabling new applications in cultural education, content creation, and digital preservation of classical Japanese literature.
AI models have disproven three major mathematical conjectures in recent weeks: ChatGPT refuted Erdős' Unit Distance conjecture, OpenAI's Sol found a counterexample to Grothendieck's 60-year-old question about group schemes, and Claude found a counterexample to the century-old Jacobian Conjecture. The achievements range from 1.2 million lines of Lean code for the Erdős proof down to 1,076 lines for the Grothendieck counterexample, with formalization times measured in days or weeks. Mathematicians are now considering AI tools essential for research, with some institutions offering free access to PhD students and faculty, fundamentally shifting how mathematical discovery and verification happen.
The European Innovation Council and European Institute of Innovation and Technology announced winners of the European Prize for Women Innovators, recognizing female entrepreneurs developing technologies in healthcare, space, and industrial sustainability. Three winners were selected: Katerina Spranger for AI technology to improve brain aneurysm treatment planning, Marta Oliveira for reusable space capsules, and Ella Frances Cullen for blockchain and AI supply chain traceability tools. The awards increase visibility of women founders and their contributions to Europe's technology sector.
