📰 No signal? No problem. This app lets you chat anyway
The article discusses the development of a new instant messaging app called Bitchat by Jack Dorsey, the co-founder of Twitter, which allows communication without needing an internet connection. Bitchat uses a decentralized mesh network to link people directly, eliminating the need for central servers and enabling secure messaging even when offline. The app works by using Bluetooth to send messages to nearby devices, similar to old-school chat rooms, with encryption and disappearing messages by default. Bitchat addresses challenges of the digital age, such as limited internet access, data restrictions, and digital autonomy, providing a privacy-first messaging solution. While similar apps have explored offline messaging, Bitchat’s focus on privacy and urgency in protecting online freedom sets it apart and could potentially spark a new era of communication.
📰 How to disable Gemini AI on Android and keep control of your apps
Google is integrating its AI, Gemini, with core Android apps like WhatsApp, Messages, and Phone starting from July 7, 2025. Users need to be aware of how to disable Gemini on Android to maintain privacy settings. The official information on Gemini’s behavior and how to disable it is inconsistent. Gemini can interact with other apps even if the Apps Activity setting is turned off, allowing Google to save and review interactions for AI training. Users may not see the same settings due to device model, region, or update status differences. To prevent Gemini from interacting with other apps, users can uninstall the Gemini app or block it in the Apps settings. It’s important to stay vigilant for potential future updates that may introduce Gemini functionality without consent.
📰 Lowering your electric bill could be floating in the ocean
A French startup called Seaturns has developed water pendulum turbines that harness the energy of ocean waves to generate electricity. These turbines are designed to be durable, low-maintenance, and efficient, offering a reliable source of power from the steady motion of the sea. The technology has been successfully tested offshore near Brest, France, demonstrating its durability and energy efficiency even in harsh marine conditions. Unlike traditional wave energy converters, Seaturns’ design is simple, reliable, and self-contained, making it attractive for coastal cities and island communities. Wave energy has the potential to produce significant amounts of renewable electricity globally, with estimates suggesting it could meet a substantial portion of energy demands if fully utilized. Despite challenges like inconsistent wave patterns and lower power output compared to other renewable sources, innovative systems like Seaturns’ water pendulum turbines show promise in advancing wave energy as a key player in the transition to clean energy.
📰 How AI chatbots are helping hackers target your banking accounts
AI chatbots are increasingly popular for internet interactions, offering direct answers to questions instead of link browsing. However, these tools can provide inaccurate information, posing security risks. Cybersecurity researchers warn of hackers exploiting chatbot flaws for AI phishing attacks, leading users to fake websites to steal personal data. Recent tests showed chatbots returning incorrect links, with over one-third linking to pages not owned by the companies, increasing the risk of users landing on unsafe sites. To protect against AI phishing, users are advised to verify links manually, use strong passwords, enable browser security features, report fake links, and install antivirus software.
📰 New Gmail tool makes it easy to unsubscribe from emails in bulk
Google has introduced a new feature in Gmail called Manage Subscriptions to help users easily unsubscribe from multiple mailing lists at once. The tool displays all subscribed lists in one place, allowing users to unsubscribe with just a click, reducing the need to open individual emails. This feature enhances inbox management by providing a safer and more efficient way to declutter without relying on third-party services. It is gradually being rolled out across web, iOS, and Android platforms. Additionally, users can improve email organization by setting up filters, being cautious with unsubscribe links in suspicious emails, and considering additional antivirus protection for device security.
