WiFi signals bouncing around your home or office can now create a kind of invisible picture of your body's movements, letting someone identify who you are without any camera or microphone. For those of us who value privacy, this matters because it means someone with the right equipment could potentially recognize you through a wall, using technology that's already in millions of homes. Worth knowing: if this technology becomes widespread, your WiFi router could theoretically reveal information about you without your knowledge—so it's worth understanding what devices are connected to your network and keeping your router's software updated.
A company that handles billing and payment records for hospitals has been hacked, putting nearly 4 million patients' personal health information at risk. If you've had medical treatment recently, your name, address, insurance details, or medical history could be among the stolen data. Worth knowing: check your credit reports and any mail from your healthcare provider over the next few months, as criminals often try to use stolen medical information for identity theft or fraudulent insurance claims.
When you use AI to rewrite or rephrase your words, something always gets lost in translation—the AI doesn't fully understand what you personally meant to say, so the meaning shifts even if the topic stays the same. For anyone sharing written work with others, this matters because you're responsible for every sentence you publish, and readers deserve to know your genuine thoughts rather than AI-generated sentences you didn't fully check. Worth knowing: before sharing anything an AI has helped you write, read it carefully yourself and ask "Would I say this exactly this way?"—if you wouldn't stand behind it in a conversation, don't put it in your document.
Google has added a new shield to Chrome called device-bound session credentials, which stores a special security key deep inside your computer's hardware—a bit like keeping your house key in a vault built into your front door rather than carrying it in your pocket. Hackers have grown more skilled at stealing the invisible "session cookies" that websites use to keep you logged in, so this built-in protection makes it much harder for them to hijack your accounts even if they manage to intercept those cookies. Worth knowing: this feature is rolling out now in the latest versions of Chrome on Windows and Mac computers, so your browser may already have this protection—you don't need to do anything special to get it.
The Electronic Frontier Foundation, a digital rights organization, creates all the pictures on their website and materials by having human designers draw them—they don't use AI image generators (with very rare exceptions). This matters because it ensures the visuals truly reflect expert knowledge about the issues they cover, avoids any copyright confusion that could complicate their work, and shows readers that their trusted information comes from real people, not machines. Worth knowing: if you follow organizations online, you can now check whether their images have human artist credits, which is becoming one way to spot who's using AI versus human creativity.
Criminals are breaking into people's email and social media accounts to find and steal private intimate photos, which they then use to blackmail victims for money. This is happening to people of all ages, and it's particularly distressing because the photos are deeply personal and the threat of exposure causes real harm and fear. Worth knowing: if you use the same password across multiple accounts, change it now—criminals often hack one site and use those credentials to access others, so using unique passwords for email and important accounts makes you much harder to target.
Schools are increasingly sharing photos of students on their websites and social media, which is convenient for families but raises real concerns about how those images might be used by people with bad intentions. If you have grandchildren in school, it's worth understanding that these photos could potentially be collected and misused in ways that schools don't always anticipate or prevent. Worth knowing: ask your grandchild's school directly what their photo-sharing policy is, whether parents can opt out, and how they protect the images once they're online.
# Zoom Screen-Sharing Flaw
A security problem in Zoom allowed someone to take complete control of another person's computer during a video call, not just see their screen. For anyone who uses Zoom for video chats—whether with family, friends, or work—this meant a scammer or hacker could potentially access your files, passwords, and personal information without permission. Worth knowing: Zoom has fixed the problem, so make sure your app is updated to the latest version, and be cautious about sharing your screen with people you don't fully trust.
Abbott, a major healthcare company, is working with Google to use artificial intelligence to help predict blood sugar patterns in people with diabetes before problems actually occur. For anyone managing diabetes or caring for a loved one with it, this partnership could mean fewer surprise blood sugar emergencies and less guesswork about when to eat or take medication. Worth knowing: if you use a continuous glucose monitor already, watch for updates from your healthcare provider about whether this AI prediction feature might become available to you.
# MacBook and Multiple Monitors: What You Need to Know
Modern MacBooks can handle at least two external monitors at once, though the exact number depends on which model you own and how new it is. If you're thinking about expanding your workspace with extra screens for email, spreadsheets, or video calls—something many of us appreciate as we get older—a MacBook can make that happen without breaking a sweat. Before buying extra monitors, check Apple's website or ask a salesperson which specific MacBook model you have, since the newer ones (especially those with the latest chips) tend to support more screens than older versions.
Apple's iPhones have gotten better cameras, longer battery life, and faster processors over the past five years, but they still look and work much like earlier models so you won't feel lost picking one up. These improvements matter because a better camera means clearer photos of grandchildren, longer battery life means fewer midday charges, and speed means apps open instantly without frustration. Worth knowing: if you have an older iPhone that still works fine, there's no rush to upgrade—the changes are helpful rather than essential unless photography or battery life have been bothering you.
# AI Doctor's Assistant Gets Better at Listening and Looking
Google has developed an AI system called AMIE that's learning to conduct medical consultations by watching and listening to patients—much like a real doctor would—rather than just reading text on a screen. For people over 50 who worry about whether AI can truly understand complex health problems, this matters because a system that pays attention to your tone of voice, facial expressions, and body language might catch things a text-based tool would miss. Worth knowing: if your doctor mentions trying new AI consultation tools in the coming years, you can ask whether the system has been trained on real patient interactions and whether a human doctor still reviews important decisions.
