ChatGPT rolls out new free educational tools for learning
ChatGPT has recently added several tools to its platform specifically designed to help users learn. Most of them are available with a free account (in some cases, with usage limits).
These new tools include the following:
Study Mode: a tutor that helps you study, with step-by-step explanations, questions, practice exercises, corrections, flashcards, and other features. It's the best entry point into ChatGPT's new educational tools.
Quizzes: ChatGPT can put together a quiz and provide corrections and explanations for the answers.
Uploading notes or PDFs to turn them into personalized study material.
Flashcards: practice questions and personalized tutoring.
Learning Visualizations to experiment with math and science concepts.
You'll find more details on these and other topics related to ChatGPT's activity in education in OpenAI's education newsletter, "ChatGPT for Education."
The Edu Prompt: Teachers, Students, and Back-to-School AI
ChatGPT for Teachers expansion, interactive quizzes, Lynwood's AI roadmap, classroom prompts, student offers, Forum replay, and new Academy courses.
National Geographic offers a free library of nearly 2,500 resources for learning about and exploring the world
This is a resource that, once you start exploring it, you'll very likely want to bookmark.
It's National Geographic Education, a spectacular collection of nearly 2,500 educational resources used every year by millions of teachers, students, and people interested in discovering and learning more about our world.
In this digital library, which is regularly updated and expanded, you'll find interactive maps, videos, infographics, articles, activities, educational tools, thematic collections, and the chance to join virtual meetups with National Geographic explorers. You can search by topic, by age (grade level), or by content type.
Just as one example of what's available, Hot Numbers is an interactive tool that lets you visualize how human population growth affects different parts of the planet.

Help NASA scientists observe clouds
Want to help NASA improve its cloud observations? The space agency is asking for volunteers from around the world to take part in the PACE Clouds Challenge, running from September 15 to October 15, 2026.
The idea is to use the free GLOBE Observer app to photograph clouds right as the PACE satellite passes over each participant's location.
NASA wants to use these ground-based observations from users to check the measurements its PACE satellite takes from space. Specifically, the data collected during the challenge will help assess how effectively PACE measures cloud edges and overall cloud coverage.

⏭️ In Brief
A comprehensive interactive feature from The New York Times on the evolution of Hollywood box office revenue. It's been a big summer for revenue, driven more by ticket prices and premium formats than by the number of tickets sold. It includes historical charts, an inflation-adjusted comparison, per-capita ticket purchases, and other visualizations. This link is free to read courtesy of "On the Net Today":

AI company World Labs recently unveiled Atlas, its new "spatial intelligence" model that can create and reconstruct 3D scenes, generate new viewpoints, and produce video while maintaining spatial coherence. The interactive demo videos are stunning and offer a good sense of what this tool can do.
The European-Mediterranean Seismological Centre provides continuously updated information on seismic activity around the world. You can view it on a map or via a searchable list.
Datawrapper, an excellent data visualization tool we've recommended before in "On the Net Today," has published a piece that's a great example of what visual and data journalism can do: From Berlin to the world: The history behind street names. It's an analysis of Berlin's street names and the places around the world they reference.
If you want to discover interesting visualizations published by media outlets and professionals worldwide, Datawrapper's blog offers a weekly roundup called "Data Vis Dispatch." Here, for example, is this week's edition:TechRadar has just launched a new weekly newsletter on digital privacy and online surveillance called "Leave No Trace," covering "the companies and governments putting our online freedom at risk, and the people fighting back against it." The first issue is available here.
Adobe has announced new AI capabilities in Acrobat that "help quickly turn files into audio and video that people can absorb in minutes."
Here you can watch the presentation Apple gave this past Wednesday, unveiling its first foldable phone, the iPhone Duo.
And here's the thread Jacob Coxon posted on X announcing his departure from AI company Anthropic — he also previously left OpenAI — because he believes it isn't acting responsibly in the development of AI. Coxon has warned that AI could end up destroying humanity by the end of this decade.

Why?
At Xalok, we have the privilege of collaborating with and supporting media organizations across Europe and Latin America. That's meant traveling fairly regularly for years to visit newsrooms around the world.
To organize those trips, TripIt has become an indispensable tool. Just forward any flight, hotel, rental car, ferry, train, transport, or activity booking by email, and it automatically generates a complete trip itinerary.
It calculates travel times, generates maps, and adjusts for time zone changes. But above all, it lets me answer, at a glance, the most important question before leaving home: does everything actually line up?
