After creating the world’s first self-organizing drone flock, researchers at Eötvös Loránd University (ELTE), Budapest, Hungary have now also demonstrated the first large-scale autonomous drone traffic solution. This fascinating new system is capable of far more than what could be executed with human pilots.

The staff of the Department of Biological Physics at Eötvös University has been working on group robotics and swarms since 2009. In 2014, they created the world’s first autonomous quadcopter flock consisting of at least ten units. The research group has now reached a new milestone by publishing the dense autonomous traffic of one hundred drones in the journal Swarm Intelligence.

But what is the difference between flocking and autonomous drone traffic?

Plants generally orient their growth against the direction of gravity. Rotating them around an axis perpendicular to gravity can produce more complicated growth shapes that depend on the speed of rotation. The authors model this behavior and find a stable family of three-dimensional dynamic equilibria.

Lead study author Charles Cadieux, a PhD student at the University of Montreal, remarked that among all known temperate exoplanets, LHS 1,140 b is possibly the most promising candidate for confirming liquid water on the surface of an alien world.

Approximately 10 to 20 percent of the exoplanet’s mass is estimated to be water. In stark contrast, Earth’s oceans account for a mere 0.02 percent of its mass. The state of this water, whether liquid or ice, hinges on the planet’s atmospheric composition, with gases like carbon dioxide playing a crucial role.

One encouraging factor is the planet’s gentle warming by its red dwarf star, which is only one-fifth the size of our Sun. This stellar relationship suggests that the exoplanet’s surface temperature is likely comparable to that of Earth and Mars.

Alderon Games, an Australian-based developer behind the dinosaur-themed multiplayer survival game Path of Titans, announced “we are swapping all our servers to AMD” because “Intel is selling defective” CPUs — specifically 13th and 14th Gen models.

The post doesn’t mince words; it states that its customers have been reporting thousands of crashes on Intel 13th and 14th Gen CPUs (verified by the game’s crash reporting tools), and its game servers have been “experiencing constant crashes, taking entire servers down.” It also claims that it’s only a matter of time before Core i9-14900K and Core i9-13900K CPUs that have yet to fail will fail.

“Over the last 3 to 4 months, we have observed that CPUs initially working well deteriorate over time, eventually failing,” Matthew Cassells, Founder of Alderon Games, writes. “The failure rate we have observed from our own testing is nearly 100%, indicating it’s only a matter of time before affected CPUs fail.”

Physicists at the University of Konstanz have discovered a way to imprint a previously unseen geometrical form of chirality onto electrons using laser light, creating chiral coils of mass and charge.

This breakthrough in manipulating electron chirality has vast implications for quantum optics, particle physics, and electron microscopy, paving the way for new scientific explorations and technological innovations.

Understanding Chirality and Its Implications.

The element actinium was first discovered at the turn of the 20th century, but even now, nearly 125 years later, researchers still don’t have a good grasp on the metal’s chemistry. That’s because actinium is only available in extremely small amounts and working with the radioactive material requires special facilities. But to improve emerging cancer treatments using actinium, researchers will need to better understand how the element binds with other molecules.
