Researchers from Tohoku University and Future University Hakodate in Japan have successfully trained cultured rat cortical neurons to perform real-time machine learning computations. By integrating living neurons with microelectrode arrays and microfluidic devices, the team created a closed-loop reservoir computing system capable of autonomously generating complex signals, such as sine waves and chaotic waveforms, without external input. The study utilized PDMS microfluidic films to constrain neural connections, preventing the excessive synchronization that typically hinders learning in unpatterned cultures. This breakthrough demonstrates that living neuronal networks can serve as novel computational resources, potentially paving the way for significant advancements in the development of sophisticated brain-machine interfaces and neuroprosthetic devices.
AutoAgent is an autonomous framework designed for agent engineering, functioning similarly to autoresearch but focused on building and iterating on agent harnesses. The system allows a user to assign a task to an AI agent, which then autonomously modifies system prompts, tools, agent configurations, and orchestration over time. By running benchmarks and checking scores, the meta-agent performs a hill-climbing optimization, keeping improvements and discarding failures. The core workflow involves programming via a Markdown file called program.md, which provides context and directives to the meta-agent, while the meta-agent directly edits the agent.py harness file. This approach minimizes manual engineering by allowing the agent to optimize its own performance through continuous, automated experimentation.
AutoAgent is a revolutionary open-source library designed to automate the tedious process of agent engineering and prompt tuning. By employing a meta-agent, the library allows for the autonomous optimization of an agent's harness, including system prompts, tool definitions, and orchestration strategies, all without human intervention. During a 24-hour run, AutoAgent achieved impressive results, including the top score on SpreadsheetBench and a leading GPT-5 score on TerminalBench. This technology effectively transitions the human's role from a manual engineer to a high-level director, enabling rapid, self-improving agent development across various domains and benchmarks.

This article explores five Python scripts designed to streamline and automate the process of feature selection in machine learning projects. Feature selection is crucial for improving model performance, reducing complexity, and identifying the most impactful variables.
The scripts cover techniques like filtering constant features, eliminating redundant features through correlation analysis, identifying significant features using statistical tests, ranking features with model-based importance scores, and optimizing feature subsets with recursive elimination. Each script is practical, minimal, and provides detailed reports to aid in understanding the selection process.
These tools are valuable for data scientists looking to systematically evaluate feature importance and build more efficient and accurate models.

A-Evolve, a new framework developed by Amazon researchers, aims to revolutionize the development of agentic AI systems. It addresses the current bottleneck of manual tuning by introducing an automated evolution process. Described as a potential "PyTorch moment" for agentic AI, A-Evolve moves away from hand-tuned prompts towards a scalable system where agents improve their code and logic iteratively.
The framework centers around an ‘Agent Workspace’ with components like manifest files, prompts, skills, tools, and memory. A five-stage loop—Solve, Observe, Evolve, Gate, and Reload—ensures stable improvements. A-Evolve is modular, allowing for "Bring Your Own" approaches to agents, environments, and algorithms, and has demonstrated State-of-the-Art performance on benchmarks like MCP-Atlas and SWE-bench Verified.

This article details a test of five local AI coding models – Qwen3 Coder Next, Qwen3.5-122B-A10B, Devstral 2 123B, gpt-oss-120b, and Omnicoder-9B – using a specific prompt to build a CLI static site generator in Python. The author found a significant performance gap, with Qwen3 Coder Next consistently outperforming the others, especially when utilizing Context7 for live documentation access. The test highlights the importance of accessing documentation to overcome biases in training data and the challenges local models face in consistently leveraging these tools. The article also points out common mistakes made by all models due to training data biases.
Greg Kroah-Hartman, a long-term Linux kernel maintainer, has observed a significant shift in AI-driven activity around Linux security and code review. Previously receiving "AI slop" – inaccurate or low-quality reports – the past month has seen a marked improvement in the quality and relevance of AI-generated bug reports and security findings across open-source projects. While the cause of this change remains unknown, Kroah-Hartman notes the kernel team can handle the increased volume, but smaller projects may struggle. AI is increasingly used as a reviewer and assistant, and is even beginning to contribute patches, with tools like Sashiko being integrated to manage the influx.
