A Pew Research Center survey across 37 countries finds that majorities in 34 nations believe AI will reduce jobs rather than create them, with concerns especially high in wealthy countries like the U.S., Australia, and South Korea. Young adults, women, and highly educated respondents express greater concern about job losses, while many people remain uncertain about AI's economic impact. Additionally, people are more likely to expect AI will increase wealth inequality between rich and poor.
MIT economists Banerjee and Duflo argue in Poor Economics that development should focus on tested small improvements rather than big-picture questions. They examine education in developing countries, noting that government schooling has failed to deliver quality education to the poor, yet argue public schooling should remain central despite evidence that private schooling outperforms it.
Tutor-MCP is an open-source adaptive learning engine built on the Model Context Protocol that creates personalized learning paths and AI tutoring for any subject.

Timothy Gowers, a Fields medalist, explains why he declined to sign a letter by 25 Fields medallists regarding a mathematical crisis. He agrees with concerns about the field but offers a different analysis, and clarifies his independence from OpenAI despite having access to their models.
A developer shares Pitch Recognition, a free web-based ear training tool designed to help users learn to identify musical pitches by name. The platform offers six free demos without signup and additional exercises for registered users, including relative ear training exercises.
Margin is a macOS app designed to help students study technical PDF textbooks more effectively. It lets users add notes and explanations directly beside text, organize related notes into scratchpads by topic, and revisit their work through an interactive book map. The app saves locally without requiring subscriptions or accounts, works offline, and supports PDFs up to 2,000 pages on Apple silicon Macs running Sonoma or later.
Children's media has increasingly adopted rapid pacing, loud sounds, and bright visuals that overwhelm young viewers' ability to process meaning and develop emotional understanding. While content quality matters, the accelerated tempo—driven by attention economy principles—prevents children from taking time to follow stories, grasp concepts, or recognize social repair, potentially undermining their development of empathy and sustained attention.
Distributed System Illustrated is an educational series using diagrams and intuitive explanations to teach core distributed systems concepts, including replication, consistency, data partitioning, consensus algorithms, and logical clocks. A complete PDF e-book version is available on Leanpub for offline reference.

Founded by researchers from Tesla and Google, it's trusted by universities and enterprises globally, offering features like plagiarism detection, multilingual support across 20+ languages, and the ability to detect humanized AI content.
A self-taught scientist reflects on how unconventional homeschooling and avoidance of formal mathematics education shaped their career. Despite lacking traditional academic foundations, they developed problem-solving skills through self-directed learning and eventually pursued science through community college, though they struggled with pre-calculus.
Alongside is a learning tool that creates an editable whiteboard alongside any webpage, using AI to draw explanations for YouTube lectures, GitHub pull requests, or custom topics. Built with Strands Agents SDK and Excalidraw, it runs as a Chrome extension with backend infrastructure on AWS, supporting saved lessons and follow-up questions.

The Association for Human Mathematics (AHM) is an organization dedicated to protecting mathematics as a human discipline against threats posed by artificial intelligence. The group argues that AI tools undermine mathematical understanding and scientific practice, and calls for coordinated action by mathematicians to address disruptions in education, publishing, and the field's independence from corporate interests.
A high school senior in Upstate New York was suspended for bringing coffee to class, which she characterized as civil disobedience to protest a new food and drink policy. The student discovered the district had failed to hold a required public hearing before adopting the code of conduct, prompting the district to acknowledge the procedural error and schedule a retroactive hearing.
Socratic Algo Coach is an open-source Chrome extension that helps competitive programmers learn through guided questioning rather than direct answers. It integrates with platforms like Codeforces and LeetCode, uses OpenAI's API for tutoring, and stores user data locally without backend servers or analytics.
