Tech & Apps

Apple overhauls App Store rules for the European Union

Apple is overhauling its App Store terms for developers in the European Union, replacing the per-install Core Technology Fee with a single Core Technology Commission, according to The Verge. The new structure sets tiered commissions ranging from 5% for apps distributed through third-party marketplaces or the web up to 26% for apps that use both the App Store and Apple’s own payment system, per 9to5Mac. Apple says the changes, which take effect October 1, 2026, resolve its dispute with the European Commission over business terms.

Comcast turns millions of routers into motion sensors

Comcast is rolling out a free, opt-in Wi-Fi motion-sensing feature called “Wi-Fi Motion” to millions of existing Xfinity routers, turning them into activity monitors without any new hardware, according to The Verge. Part of the new Xfinity Shield service, the feature works on compatible gateways by reading disruptions in Wi-Fi signals and sending alerts through the Xfinity app. If your other gadgets tend to run hot, see our guide on stopping your Android phone from overheating while charging.

Apple services outage briefly hit Find My and iCloud

Several Apple services — including Find My, iCloud Mail, iCloud web apps, and Xcode Cloud — went down for some users starting around 3:30 p.m. ET on August 18, 2026, according to 9to5Mac.

China reportedly cleared to import H200 AI chips

China has reportedly allowed ByteDance and Tencent to import 10,000 Nvidia H200 AI chips each, according to a Financial Times report cited by Engadget. The report says other Chinese companies could be approved for similar imports, but neither government has officially confirmed the figures, so treat this as unconfirmed for now.

Deus Ex creator Warren Spector retires from game development

Warren Spector, the designer behind Deus Ex and a pioneer of the immersive-sim genre, announced his retirement from game development in a LinkedIn post, according to Engadget. Spector cited age and health after roughly 44 years in the industry and said he plans to write, lecture, and consult going forward.

Firefox adds an opt-in ad blocker on iOS

Mozilla is rolling out an experimental, opt-in ad blocker for Firefox on iOS that filters ads and trackers using an EasyList-based filter before pages load, according to Lifehacker. It has to be switched on manually in the browser’s content settings, is rolling out gradually rather than to everyone at once, and doesn’t block ads that appear in search results or on Firefox’s own new tab page.

Firefox’s “Smart Window” gets three new features

Firefox is adding three features to its AI-powered “Smart Window” mode: live web answers with cited sources, smarter tab organization with automatic tab-group suggestions, and visual previews of browsing history, according to Lifehacker. Mozilla announced the update on August 18, 2026, and the features are currently limited to English-language users in the US and Canada.

AI Tools

OpenAI launches ChatGPT for Teens

OpenAI launched ChatGPT for Teens on August 18, 2026, a version of the chatbot for users ages 13 to 17 that adds extra protections around topics like self-harm and violence, according to TechCrunch. The system automatically applies teen settings when it estimates a user is under 18, and lets parents link accounts, set “Quiet Hours,” and receive notifications in limited high-risk situations. It also includes a Study Mode built to guide teens through homework rather than simply handing over answers.

Cursor launches Origin, a GitHub rival

AI coding startup Cursor launched a new code-hosting platform called Origin on August 18, 2026, aiming to compete with GitHub on pull requests, code review, and repository storage, according to TechCrunch. Origin is built to interoperate with GitHub, letting repositories sync between the two platforms, and launched with day-one integrations from Vercel, Depot, and Buildkite. The timing was notable: GitHub experienced a roughly six-and-a-half-hour outage that same day.

Science & Space

SpaceX hits 100 launches for 2026

SpaceX launched its 100th mission of 2026 in the early hours of August 19, sending 24 Starlink satellites into orbit aboard a Falcon 9 from Vandenberg Space Force Base, according to Space.com. The mission was part of the Starlink Group 17-50 batch.

Climate modeling points to more intense future tropical storms

A new modeling study suggests that under a high-emissions future scenario, organized tropical storm systems could start forming 10 to 15 days later in the season and grow 38% to 45% more intense, according to ScienceAlert. The findings come from climate simulations rather than an observed storm, and researchers say the shift could reshape rainy seasons across the tropics in the coming years.

Study links daily sugary drinks to higher stomach cancer risk

A study published August 17, 2026 in Gastro Hep Advances found that people who drank sugar-sweetened beverages daily had roughly 2.45 times the risk of developing stomach cancer compared to those who rarely or never drank them, according to ScienceAlert. The research followed more than 112,000 participants in two long-running US health studies and tracked 278 gastric cancer cases; researchers note it shows a correlation, not proof that sugary drinks cause cancer.

Climate change is the main driver of Europe’s ocean warming this summer

A rapid analysis from World Weather Attribution found that climate change is the main driver of this summer’s ocean warming in Europe, adding roughly 2°C to Mediterranean Sea temperatures and about 1.3 to 1.4°C to seas in Western Europe, according to Phys.org. Some areas were more than 6°C above normal at their peak, with roughly 90% of the Bay of Biscay and 80% of the western Mediterranean experiencing marine heatwave conditions.

Italian scientists release octopuses to fight invasive crabs

Researchers at the University of Bologna have released roughly 80,000 octopus hatchlings into the Adriatic Sea since June 2026 as part of an ongoing effort to combat invasive Atlantic blue crabs, which have caused an estimated €17 million in damage to local fisheries since 2022, according to Phys.org. The project, based out of a lab in Cesenatico, plans to double the number of released hatchlings by the end of August, though researchers note the common octopus doesn’t naturally favor the sandy, warm lagoon habitats crabs prefer.
