If you're tired of tripping over speaker wires but still want that immersive home theater experience, Popular Science has rounded up the top wireless surround sound systems for 2025. They’ve tested and reviewed the latest setups so you don’t have to guess which ones actually deliver crisp, room-filling audio without the cable clutter.

Editor’s Note: Wireless surround sound systems are a game-changer for home entertainment, blending convenience with high-quality audio. This review matters because it cuts through the marketing hype and gives real-world insights—helping you invest in a system that actually lives up to the promise of wire-free cinematic sound. No more crawling behind furniture to untangle cords!

Scientists have cooked up a clever way to turn kitchen scraps—like eggshells, coffee grounds, and flower stems—into a bioplastic paste that can be 3D-printed into useful items like mugs and coasters. It’s a quirky yet practical twist on recycling, turning what would’ve been trash into functional (and probably conversation-starting) household objects.

Editor’s Note: This isn’t just a fun gadget trick—it’s a small but creative step toward tackling food waste and plastic pollution. Imagine if your morning coffee grounds could literally become your next coffee cup. While it’s not a silver bullet for sustainability, it’s the kind of outside-the-box thinking that makes circular economies feel a little more tangible. Plus, who wouldn’t want a coaster with a backstory like "made from yesterday’s omelet"?

Workers renovating an ice cream shop in Poland stumbled upon something far older than their freezer—a medieval knight’s grave, complete with a sword and other artifacts. Archaeologists are calling it a major find, offering a rare glimpse into the region’s past.

Editor’s Note: It’s not every day that a scoop shop leads to a historical breakthrough. This discovery isn’t just cool—it’s a chance to learn more about medieval life in Poland, proving that sometimes the past is hiding right under our feet (or our waffle cones).

The James Webb Space Telescope just caught two dying stars in a dramatic cosmic showdown. Nicknamed "Apep" after the Egyptian serpent god of chaos, this binary system is basically hurling its own scorching stellar guts at each other—like a fiery, high-speed spat in deep space. Webb’s infrared vision reveals the messy details of their mutual destruction.

Editor’s Note: This isn’t just a wild space spectacle—it’s a rare peek into how massive stars behave when they’re on the verge of blowing up. Systems like Apep help scientists understand the chaotic final acts of stellar lives, which can shape entire galaxies. Plus, who doesn’t love a cosmic drama with a mythological twist?

Up on the ISS this week, the Crew-10 astronauts started prepping for their return trip—but not before whipping up some cosmic comfort food. One crew member even made "space kimchi fried rice," proving that zero-gravity cooking can still be delicious (and creative). Meanwhile, they checked in with Earth to share updates on their experiments and life aboard the station.

Editor’s Note: Beyond the cool factor of space kimchi, this story highlights how astronauts keep things relatable—even 250 miles above Earth. It’s a reminder that space missions aren’t just about science; they’re about humans adapting, innovating, and yes, even craving home-cooked meals. Plus, it subtly builds excitement for their upcoming return and the next chapter of orbital research.
