NASA White Dwarf Merger Collision
A white dwarf star is as dense as a city squished into the size of the Earth. Usually that’s the end of a star’s life. But sometimes they don’t go quietly. An international team of astronomers using NASA’s Hubble Space Telescope discovered a rare beast: an ultra-massive white dwarf formed by a catastrophic collision with another star rather than a steady fading.

3D-Printed Rainwater Filter Self-Cleaning
Rainwater collection is supposed to be simple—set up a barrel, catch the drops, water your plants. But anyone who’s tried it knows the messy reality: leaves, twigs and roof grit clogging filters faster than you can say “downpour.” This clever solution by NeedItMakeIt consists of a 3D-printed self-cleaning water filter, inspired by hydroelectric systems, that promises to keep your rain barrel flowing without the hassle.

Insta360 Antigravity A1 First 8K 360 Drone
Flying a drone means making split second decisions about where to point the camera. You’re either chasing a perfect shot or cursing yourself later for missing it. Insta360’s Antigravity A1 changes the game entirely. This is the world’s first 8K 360-degree drone, a device that captures everything around it in one go and lets you decide what matters most after you land.

Arm Mobile Graphics Neural Super Sampling (NSS) Technology
Mobile gaming has always been a balancing act, as developers have to juggle sharp visuals, smooth performance and battery life, often making compromises to keep everything in check on the limited hardware of smartphones. Arm, a company whose chip designs power most of the world’s mobile devices, is changing that equation with Neural Super Sampling (NSS), paired with dedicated neural accelerators in future Arm GPUs.

Solar power has always felt like a broken promise—it has a lot of potential but never quite delivers. A team from the University of Rochester, led by optics expert Chunlei Guo, may have just changed that. They’ve created solar thermoelectric generators (STEGs) using black metal that are 15 times more powerful than previous generations.
