German police disarmed a drone carrying explosives after it was discovered near Ukrainian cargo aircraft parked at Leipzig airport—and authorities are looking into the possibility of a second drone after an approaching aircraft collided with something midair.
The drone, first spotted by an airport employee, was hovering close to the ground between two parked An-124 cargo aircraft owned by Ukraine’s Antonov Airlines shortly before midnight on August 4, according to The Guardian. It had apparently been modified to help avoid detection by the airport’s drone defense sensors, said Alexander Dobrindt, federal minister of the interior for Germany, during a press conference.
Dobrindt described the drone as carrying a fist-sized package of a substance believed to be the plastic explosive Semtex. Only a failed detonator prevented the drone from exploding near the Ukrainian cargo aircraft, he said.

Après plusieurs années de compétition entre passionnés, le record de vitesse des drones électriques change de dimension. Une entreprise allemande affirme avoir franchi un nouveau cap avec un prototype dont la technologie pourrait bientôt trouver des applications bien plus concrètes.
Chinese researchers are using laser technology to vastly extend the flight time of drones, marking a significant shift in UAV capabilities.
The achievement was reported by researchers from China’s Civil Aviation University, who reported their findings in laser-based drone charging technology in a recent article published in Matter & Light.
The new drone concept utilizes a lightweight receiver, repurposing solar cell technology to absorb laser light and convert it into electricity to power a device.
Endless Drones
“Imagine a future where drones inspecting forests, monitoring disasters, or delivering packages no longer need to land frequently to replace batteries,” said senior author Jianhua Han of Civil Aviation University of China. “As drones take on longer missions, battery life has become one of the biggest barriers.”
At the core of the breakthrough is perovskite, a class of synthetic compounds with a crystalline structure highly conducive to solar power applications. The team developed a perovskite laser cell-thermoelectric (PLC-TE) tandem device that optimizes a solar cell to accept laser energy.
In laboratory tests, the perovskite laser receiver effectively powered the propeller on a stationary drone model (Image Credit: Y. Han and X. Han et al., Matter & Light)
The cell’s perovskite converts laser energy into electricity, which can be a messy process, as some of the power is lost as heat. The thermoelectric layer addresses this problem by capturing heat and converting it into electricity via the temperature differential between its warmer, laser-facing side and its cooler side. However, that contrast requirement can be an issue when the laser uniformly heats the entire drone, reducing the efficiency of that heat-to-energy conversion.
Managing Overheating
“When we tested the device under a high-power laser, the thermal camera showed temperatures of 80 to 90 degrees Celsius,” Han said. “That was much higher than we expected and made us realize that heat buildup was a far more serious problem than we had imagined.”
To mitigate overheating concerns, the receiver was mounted on the drone’s wings, kept separate from other components, and paired with heat-blocking technology to enable laser-to-electric energy conversion without overheating sensitive electronics.
This heat-blocking technology included nanocrystals embedded in the PLC-TE tandem device, which acted as a thermal barrier due to their poor thermal conductivity. With the nanocrystals in place, the researchers tested the conversion device on its own and observed a significant slowdown in heat flow during prolonged laser exposure, which would cool the drone overall.
This PLC-TE device was bombarded with a green laser in a laboratory experiment and converted 38.49% of the beam’s energy into electricity, a high percentage compared to other wireless charging systems in similar scenarios.
Drone Tests
Next, the team integrated the energy conversion system onto a stationary lab drone and also added airflow channels to the wings. In subsequent laboratory tests, laser bombardment supplied sufficient energy to power the drone’s propeller, while the airflow channels effectively cooled the thermoelectric layer’s cold side, maximizing heat-to-electricity conversion.
“Previous studies largely focused on the materials or the device itself,” Han explained. “We wanted to think beyond the laboratory, to how the system could actually be integrated into an aircraft, cooled during operation, and made compatible with flight. It isn’t just a materials science problem; it’s an engineering one.”
Work continues on this wireless drone charging system, with outdoor flight tests on a lightweight frame scheduled. These will be paying particular attention to the system’s reliability under real-world outdoor conditions. However, the team notes that energy conversion efficiency will not be their sole research area, as the accuracy of laser tracking will be essential to the system’s safe operation.
“Our work demonstrates the possibility of ‘refueling aircraft with light,’” Han concluded. “Going from 1 to 100 will require solving many engineering challenges, but we hope this provides a starting point for future development.”

An innovative new drone dubbed the “Phantom Twist” can seemingly disappear from view, in a major new robotics advancement offering a close-to-invisible aerial platform.
Its name describes the drone’s rapid spinning motion, which rotates 25 times per second—too fast for the human eye to resolve—thereby acting as a sort of cloak shielding it from visible detection.
The Northwestern University engineering team behind the Phantom Twist revealed their drone during a recent talk at the Sydney, Australia, Robotics: Science and Systems 2026 conference on July 16.
Stealth Drones
“Most efforts to hide drones focus on making them look like their surroundings,” said Northwestern’s Michael Rubenstein, who led the work. “Instead, we asked whether we could design the drone itself around the way humans perceive motion. This idea of low visibility through persistent motion is something few people have explored.”

Hiding drones is not a new idea. Other engineers have attempted a variety of techniques, including camouflage, transparent materials, and light-bending to obscure the presence of drones and robots. However, all of those focused on the material the drone’s exterior was constructed from, allowing it to blend into the background. The Northwestern team’s innovation was in how the object moves.
To our eyes, fan blades disappear because they are moving so fast that our eyes cannot track them. The “motion blur” created at these speeds allows the Phantom Twist to almost disappear, leaving only a faint apparition perceptible to the eye.
Nature Drones
While several military applications are immediately obvious, the team instead says their work could be useful in developing noninvasive wildlife and environmental monitoring. Loud drones can scare wildlife, disrupting them as they scatter, but by blending in, the Phantom Twist could capture a much more accurate picture of natural behaviors.
Their perception-based design eschews the traditional quadcopter design for a single propeller, with a body that spins in the opposite direction, creating the optical illusion that the drone essentially disappears.

“For a typical quadrotor drone, the propellers are spinning, but the robot is stationary,” Rubenstein said. “So, you still see its body. For our drone, the whole thing is rotating, so there are no stationary parts.”
Creating the Phantom Twist
Using AI and optimization algorithms, the Northwestern team began by generating 20,000 different arrangements of a drone’s propeller, motor, circuit board, and other necessary components. Eventually, the algorithm landed on the most promising configurations, after which the researchers simulated and superimposed them onto real-world backgrounds.
Another computer model mimicked human perception, allowing the engineers to assign a perception score for how visible each design would be to human eyes. An algorithm then optimized those designs by moving components to minimize the visibility score even further.
“The design process was fully automated,” Rubenstein said. “Then, when we were confident that a drone met all our criteria, we built it.”
A Revised Drone
The key feature of this design is that the individual components are at such varying heights and angles that they do not overlap as it spins, maximizing the motion-blur effect and creating the appearance of a faint cloud rather than a solid object.
“The human eye takes time to accumulate signals, roughly analogous to the exposure time of a camera,” said Alexander, an expert in computer vision. “When an object spins quickly, we perceive it as blurring out and losing distinct features. Because this new drone is almost entirely transparent, its few opaque components are visually averaged with the background for an overall appearance of a slight haze.”
Currently impeding the drone from being even more imperceptible to the eye are the wires and support rods that remain visible, as well as the engine noise it produces, which is readily discernible. Going forward, the team plans to continue improving Phantom Twist in future iterations to incorporate more transparent materials and reduce the noise it produces.

President Donald Trump’s latest pitch for using taxpayer dollars to secure his White House ballroom featured a militarized building—including a rooftop hardened against drone strikes and a “drone port” that could potentially house military drones.
The remarks came on May 19 as Trump gave reporters a personal tour of the ballroom project that has already involved the demolition of the White House mansion’s East Wing. The president spoke of installing a rooftop drone base “for unlimited numbers of drones” operated by the US military as a “drone port that would protect all of Washington,” according to Reuters. He also highlighted a ballroom roof made from “impenetrable steel” that would supposedly be “drone-proof” against potential drone strikes.
To pay for such measures, Trump has been urging Republican lawmakers in the US Congress to approve $1 billion in taxpayer funding to provide a wide variety of “security adjustments and upgrades” for his ballroom project. The taxpayer-backed security enhancements would be separate from the $400 million construction cost for the ballroom project that has been funded by private donors, including companies such as Amazon, Apple, Coinbase, Comcast, Google, HP Inc., Lockheed Martin, Meta, Micron Technology, Microsoft, Palantir, Ripple, and T-Mobile.
