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.
This review examines Google’s LangExtract, a library designed to solve the "production nightmare" of inconsistent data extraction from large documents using standard LLM APIs.

This article explores how temperature and seed values impact the reliability of agentic loops, which combine LLMs with an Observe-Reason-Act cycle. Low temperatures can lead to deterministic loops where agents get stuck, while high temperatures introduce reasoning drift and instability. Fixed seed values in production environments create reproducibility issues, essentially locking the agent into repeating failed reasoning paths. The piece advocates for dynamic adjustment of these parameters during retries, leveraging techniques like raising temperature or randomizing seeds to encourage exploration and escape failure modes, and highlights the benefits of cost-free tools for testing these adjustments.
WebMCP is a new technology that allows AI agents to interact with web pages more directly. It works by turning web pages into MCP (Model Context Protocol) servers via a Chrome extension. This enables agents to understand and manipulate web content in a structured way, potentially improving efficiency and user experience.
The technology, backed by Google and Microsoft, is designed to work alongside human users, allowing them to ask agents questions about the page they are viewing. WebMCP uses a Declarative API for standard actions and an Imperative API for more complex tasks. Early experiments demonstrate the ability to query web pages and receive structured data back.

This article features Noyuri Mima, professor at Hakodate Future University, and explores her journey in the field of science and technology. Miwa recounts a pivotal moment in her youth when she visited the Japan IBM headquarters in 1977 and witnessed a computer instantly print a calendar based on her birthdate. This experience ignited her passion for computers. The article delves into her background, including her education at Toyo English Women's College and her early interest in mathematics and science, highlighting her as a pioneer for women in STEM.
Grindr's Chief Product Officer, AJ Balance, discusses the company's significant investment in AI, with 70% of its code now being checked via AI tools like Claude Code, OpenAI, and GitHub Copilot. This shift is changing the role of software engineers, moving them towards more code review and agent coordination. The company is also testing a premium "Edge" subscription tier at high price points, justifying the cost based on the value it delivers to users seeking enhanced connections. Balance also addressed concerns about ad density and subscription fatigue, outlining plans for ad format improvements and a focus on maintaining a positive free user experience.
Companies that rapidly adopted AI are now focusing on evaluating their employees' understanding and effective use of the technology. Workera, a business skills intelligence platform, is assisting companies in assessing AI fluency, which extends beyond simply knowing how to use tools like ChatGPT.
Their framework evaluates understanding in three areas:
Here's a summary of Workera's AI fluency framework, as described in the article:
* **AI Fundamentals:** Assesses understanding of core AI concepts like the differences between machine learning, deep learning, and generative AI, as well as the ability to describe AI agents.
* **Generative AI Proficiency:** Evaluates skills in writing AI prompts, identifying inaccuracies ("hallucinations") in AI-generated outputs, and understanding how large language models function.
* **Responsible AI Awareness:** Tests understanding of biases within AI systems (algorithmic, data, and human) and recognition of potential privacy risks associated with AI.
AI fundamentals, generative AI capabilities like prompt writing and hallucination detection, and responsible AI practices including bias and privacy awareness. Initial assessments reveal a significant gap between self-perceived and actual AI skill levels, highlighting the need for targeted upskilling initiatives. This shift signifies a move from access to measurement in tech education.

This article discusses the recent wave of AI-driven layoffs in the tech industry, with companies like Atlassian and Block citing AI automation as a key reason. It explores the growing debate between the Model Context Protocol (MCP) and APIs for connecting AI agents, with some developers favoring APIs for their simplicity and efficiency. The piece also highlights the increasing trend of using Mac Minis as dedicated hosts for AI agents, and the rapid growth of platforms like Replit and Claude, indicating a shift in how software is developed and deployed with the aid of AI.
This article details the rediscovery of the source code for AM and EURISKO, two groundbreaking AI programs created by Douglas Lenat in the 1970s and early 80s. AM autonomously rediscovered mathematical concepts, while EURISKO excelled in VLSI design and even defeated human players in the Traveller RPG. Lenat had previously stated he no longer possessed the code, but it was found archived on SAILDART, the original Stanford AI Laboratory backup data, and in printouts at the Computer History Museum. The code was password protected until Lenat's passing, and has now been made available on Github.
