Bright idea

💥 Bright idea: This is amazing. Scientists in Texas found a way to zap cancer cells using plain ol’ LED bulbs and tin oxide nanoflakes. It’s basically a sunburn with superpowers. After 30 minutes, up to 92% of skin cancer cells were toast, while healthy cells chilled. It’s still early days, but imagine treating cancer with a bedside lamp instead of chemo and radiation.

Open the Photos app, then tap Collections > Utilities > Receipts. Or use the search icon (the little magnifying glass) and type something like “parking receipt.” No more endless scrolling.

🔎 Scammers on Facebook Marketplace: It’s tough to tell who’s legit, so start by checking when the seller joined. Scroll to Seller information on their post. Profiles that are under a year old, private or blank are red flags. But that’s not a 100% guarantee all is legit. If there’s a phone number, search it in Groups for warnings. And always meet in public and bring a friend.

🎨 Better AI images: The next time you use an AI image generator like Bing, imagine you’re giving directions to an artist who takes things literally. Start with your main subject, then layer in details such as color, background and mood. Don’t forget the style. Try “watercolor,” “realistic photo,” “Pixar style,” “vintage film” or even “cyberpunk.” And always say what to avoid. Example: “A happy golden retriever in an autumn park at sunset chasing a ball, Pixar style. No people.” The clearer you are, the better the magic turns out.
