Young sellers are using TikTok to auction lab-grown diamonds at bargain prices, attracting buyers who are shocked by how cheap they are compared to traditional mined diamonds. For people considering a diamond purchase or thinking about the value of jewelry they already own, this trend shows how the diamond market is shifting—lab-grown stones are chemically identical to mined ones but cost a fraction of the price. Worth knowing: if you're tempted by these livestream deals, experts caution that buying from unvetted sellers means you may not know the true quality or authenticity of what you're getting, so it's wise to stick with established jewelers who offer guarantees.
Humanoid robots – machines built to look and move like people – are becoming much more capable and practical right now, which is why companies and researchers are investing heavily in them. For older adults, these robots could eventually help with tasks like companionship, reminders to take medication, or assistance around the home, especially as the population ages and caregiving needs grow. You can start noticing how these robots appear in news stories and think about whether a helpful robotic companion might make sense for your situation down the road.
Job hunting has become a frustrating numbers game where you can apply to dozens of positions with just a few clicks, but companies use AI filters to reject most applications automatically—many people now suspect half the job postings aren't even real openings. For people in their 50s and beyond, this matters because re-entering the job market after a career change or retirement can feel impossibly discouraging when you're competing against thousands of applicants and never knowing if a human will actually review your application. Worth knowing: before spending hours tailoring applications online, consider networking directly with people at companies you're interested in—a warm introduction from someone inside still beats an algorithm every time.
Pebble has made a smartwatch that skips all the complexity and fancy features, instead focusing on fun watch faces, simple apps, and buttons you can actually press instead of swiping. Unlike fancier smartwatches that need charging every day or two, the Pebble Time 2 runs for weeks on a single charge and uses a crisp, easy-to-read screen that works perfectly in bright sunlight. You can try one out at a tech store or read independent reviews online to see if its straightforward approach appeals to you more than the bells and whistles of pricier alternatives.
LinkedIn has added a button that lets you hide posts created by AI rather than real people, and the company says it's successfully reducing the spread of low-quality AI-generated content on your feed. For those of us who spend time on LinkedIn to stay connected with friends and professional contacts, this means you're less likely to see repetitive, generic posts that don't add real value to conversations. Worth knowing: if you start seeing fewer motivational quotes and hollow "thought leadership" posts in your feed, it's probably this filter working behind the scenes—though you can also manually report or hide posts you find unhelpful.
Walmart is finally letting customers use Apple Pay and other tap-to-pay options at checkout, starting this month in some stores and spreading to all locations by year's end. If you've felt frustrated watching others tap their phones or watches to pay while you had to scan a QR code, this change means you'll have the same convenient choice—no wallet needed, just your phone or smartwatch. Worth knowing: Check your local Walmart's website before your next visit to see if tap-to-pay is available yet, and make sure your phone or watch has Apple Pay or another tap option set up in its settings.
Walmart and Sam's Club are planning to let you pay for your purchases by tapping your phone or smartwatch at checkout by the end of 2026, catching up with most other major retailers who already offer this feature. If you use mobile payment apps like Apple Pay or Google Pay, this means one less thing to carry—your wallet can stay at home if you want. Worth knowing: check whether your bank or card issuer already supports tap-to-pay payments, as many do, so you might be able to start using this at other stores right away.
# Can Your Old Satellite Dish Pull in Free TV?
That satellite dish left behind by the previous owner might work as a regular TV antenna, but whether it actually will depends on your location and what kind of broadcasts are available nearby. For people who've cut the cord on expensive cable or satellite subscriptions, this could mean free access to local channels without buying new equipment. Worth knowing: you'll need to check if your area still has over-the-air television signals (most do), and you may need an adapter or new cable to connect the old dish to your TV.
Matt Webb used ChatGPT not to write his code for him, but to teach him how quaternions work—a tricky math concept he'd struggled to understand from books and friends. Rather than making him lazier, having AI as a patient tutor actually pushed him to learn more deeply than he would have otherwise. You can think of AI tools this way: the best use isn't dodging the work, but having a tireless teacher available whenever you're ready to dig in and understand something new.
Oura, the company behind popular sleep-tracking rings, is being sued because the rings may not actually measure what they claim to measure about your sleep. For people who've spent money on these devices hoping to improve their sleep habits, this raises real questions about whether you're getting useful information or just expensive guesswork. Worth knowing: if you own an Oura ring or similar device, check what the company actually guarantees versus what it merely suggests, and remember that a good night's sleep still depends on the basics—keeping a regular schedule and a cool bedroom—rather than gadget readings.
Walmart has decided to accept Apple Pay and Google Pay at its checkout counters, ending a long holdout against these mobile payment methods. If you prefer tapping your phone instead of carrying cards or cash, you'll now have that option at one of America's largest retailers. Worth knowing: check your phone's settings to make sure Apple Pay or Google Pay is set up before your next Walmart visit, so you can try it out smoothly.
Surgeons can now use 3D printed models of a patient's organs before surgery, allowing them to practice the exact procedure and plan their approach—which cuts operating time by up to an hour and a half. Shorter surgery means less time under anesthesia and lower infection risk, which becomes increasingly important as we age and recovery matters more. You can ask your surgeon if 3D modeling is available for your upcoming procedure, especially for complex operations like heart or brain surgery.
