One day, the night sky will be full of these dazzling light-up spherical drones

We’ve already witnessed Intel’s ambitious bid to excite us with its drone display at Disney Springs, and marveled at the astonishing “drone ballet” performed in the shadow of Mount Fuji. Heck, those bizarre “dancing drone umbrellas” even had us sitting up and taking notice. But NTT Docomo’s contribution to the field of drone-based entertainment is surely the most impressive effort yet.

The Japanese telecoms giant has developed what it claims is the world’s first spherical drone display that shows LED images on an omnidirectional spherical screen while in flight. If that already sounds a bit bonkers, then take a moment to check it out in the video above. You’ll be amazed.

Docomo’s machine consists of a quadcopter inside a spherical protective cage. Just inside this you’ll find the all-important LEDs mounted onto eight curved strips that extend from top to bottom on a lightweight frame.

As the drone fires up, the LED frame spins rapidly, with the lights forming an afterimage that creates the illusion of a solid sphere of light. The operator can program the onboard computer to show any image they like, for example an illustration or a message.

The company said it faced several challenges while building the machine, including how to prevent the rotating display’s air flow from interfering with the drone’s propellers, and how to keep the cage and frame as light as possible to reduce the strain on the drone.

It settled with a mainly hollow display that’s not only very light but also allows air to flow through to reduce resistance for greater efficiency.

With an eye on commercializing the technology, Docomo points out that its drone can be operated “virtually anywhere, including venues such as concert halls or arenas where it can fly around as part of a performance or deliver advertising messages [and] event information.”

Disney has been looking at the idea of sticking projectors on its drones and flying them in its parks, but we can well imagine plenty of potential customers knocking on Docomo’s door eager to learn more about the opportunities that its own very cool technology appears to present.

AI security cameras may soon recognize your walk before they recognize your face
A new AI gait system tracks body motion through skeletal keypoints, aiming at long-range identity checks where face scans and fingerprints fall short.

Security cameras are built to look for faces. New research suggests they may soon have another target, the small habits buried in the way someone walks.

A paper published in the International Journal of Reasoning-based Intelligent Systems describes SKDMap-Net as a gait recognition system designed to identify people from walking video, even when the camera doesn’t get a clean look at their face. Instead of relying on a close-up scan, it studies how a body moves from frame to frame.

A 20-second 3D printer breakthrough comes with exactly the kind of catch science loves
The process can create complex microstructures far faster than some laser-based methods, but full 3D control is still a work in progress.

A 3D printer that can make a structure in about 20 seconds sounds like a lab claim wearing a cape. The clever bit is real. The catch arrives before anyone starts dreaming about instant replacement parts.

University of Utah researchers have demonstrated a holographic 3D printing technique that hardens tiny structures in one exposure instead of building them layer by layer. That one-shot approach could avoid the weak, leaky seams that stacked printing can leave behind. For now, though, this is a tool for microstructures, not a shortcut to printing whatever object pops into your head.

Amazon is full of copycats and shady brands. This Chrome extension lets you avoid them.

Shopping on Amazon used to be simple. You searched for a product, compared a few familiar brands, and checked out. These days, it often feels like you're scrolling through an endless parade of names that look like someone leaned on a keyboard before hitting publish. That's exactly the problem Knockoff is trying to solve.

Created by developer Josh Pigford, the Chrome extension doesn't promise to expose counterfeit products or magically tell you what's good. Instead, it tackles something arguably more annoying: the flood of unfamiliar, mass-produced brands that dominate Amazon search results.
