# Why USB-B Stayed in the Shadows
USB-B connectors, with their distinctive square shape, were designed mainly for printers and scanners back in the 1990s, but they never caught on for everyday devices the way the flatter USB-A and newer USB-C plugs did. If you've ever struggled to plug a printer cable into your computer, you've probably encountered one of these bulkier connectors that feels unnecessarily complicated for such a simple task. Worth knowing: when your printer needs a new cable, look for USB-B on the device side — but don't worry if you have trouble finding the right one in a drawer, since many modern printers are slowly switching to USB-C instead.
Samsung's newest Galaxy Watch 9 makes only small improvements over the Watch 8 from last year—it has a slightly better processor and a brighter screen, but nothing revolutionary. If you wear a smartwatch to track your health, sleep, and daily activity, the Watch 9 does these things a bit faster and more clearly than before. Worth knowing: unless your current watch is several years old or you're frustrated with its speed, waiting another year for the next model makes more sense than upgrading now.
A new device that acts like a "cochlear implant for the eyes" has just been approved in Europe and can help people with age-related macular degeneration see well enough to read books and road signs again. For older adults losing their central vision to this common condition, this represents a real chance to regain independence and quality of life in ways that weren't possible before. You can ask your eye doctor about this technology if you've noticed difficulty reading or recognizing faces, since it may become available in the U.S. by 2027.
Hospitals across America are now using artificial intelligence to help doctors write notes, spot dangerous infections, and review medical images, but most hospitals are checking on whether these tools work safely using old-fashioned methods from over a decade ago that take months to complete. Unlike an MRI machine that stays the same once installed, AI systems can change and drift in how they perform over time, which means the slow, quarterly-review approach leaves patients at risk of unnoticed problems. Worth knowing: if you're having treatment at a hospital, you can ask your doctor whether AI is being used in your care and what safety measures the hospital has in place to monitor it regularly.
Meta is developing an AI app that generates personalized bedtime stories for people who want a break from thinking up their own tales. If you've ever struggled to wind down at night or found yourself repeating the same old story lines, this could offer a fresh way to relax before sleep without the mental effort. Worth knowing: the app learns your preferences over time, so you might want to try it for a few nights to see if AI-generated stories actually help you sleep better than a good book would.
France has passed a law that will prevent children under 15 from using social media apps like Instagram, TikTok, and Facebook, and will also ban mobile phones from schools during the school day. Young people today spend countless hours on these platforms, which research suggests can affect their sleep, mental health, and ability to concentrate—concerns that many parents share regardless of where they live. Worth knowing: if you have grandchildren in France or are curious about how other countries are tackling screen time for young people, this law shows one approach to protecting children's wellbeing and school focus.
Scientists are teaching computers and robots to detect smells by analyzing the chemicals in the air, mimicking what a dog's nose does naturally. For older adults, this could mean earlier detection of gas leaks in your home, spoiled food in your fridge, or even health problems like infections before they become serious. You can start noticing when companies mention "electronic nose" technology in home safety devices or medical products—it's already appearing in some newer appliances and healthcare settings.
AI is making it simpler for entertainment companies to blend music, videos, podcasts, and audiobooks all into one app, so instead of juggling Netflix for shows and Spotify for music, you might soon get everything in a single place. For people who've built up subscriptions over the years, this could mean either fewer apps to manage or the inconvenience of learning a new all-in-one interface you may not prefer. Worth knowing: keep an eye on which services you actually use most, as bundling everything together might tempt you to pay for features you don't need.
Substack, a popular platform where people publish newsletters and blogs, is adding a new feature that can tell you whether a piece of writing was created by artificial intelligence or a real person. This matters because AI-written content is becoming harder to spot, and knowing the difference helps you decide how much to trust what you're reading—especially important when you're following writers you've come to know and appreciate. You can use this tool yourself by clicking the three-dot menu on any post longer than 100 words and selecting "Scan for AI text" to see an estimate of how much might be machine-generated.
Substack, the platform where writers publish newsletters, is adding a tool that can identify when text was written by artificial intelligence rather than a human. For newsletter readers and writers, this matters because you'll be able to spot AI-generated content more easily, helping you decide which writers you trust and whether the information you're reading comes from genuine human expertise. Worth knowing: when you're reading a Substack newsletter, look for any AI detection badges or notices that might appear, which will give you a clearer picture of how much human effort went into what you're reading.
Apple has patched a security problem in its Hide My Email feature that was allowing people's real email addresses to be exposed when they signed up for services online. If you use iCloud+ and rely on this feature to keep your email private, the fix means your address should now stay properly hidden as intended. Worth knowing: if you use Hide My Email regularly, you don't need to do anything—the fix happens automatically on Apple's end.
CarPlay—that system that mirrors your phone onto your car's dashboard—works best with a carefully chosen handful of apps rather than cluttering it with everything. If you drive regularly and want your essential navigation, music, and messaging tools easily accessible without distraction, picking the right apps can make trips safer and more enjoyable. You can start by installing just three or four apps you use most (like maps, your favorite music service, and messaging) and add others only if you find yourself actually reaching for them while driving.
