After forty years, the creator of scar theory has observed the phenomenon in real time.

Quantum scarring is a phenomenon in which traveling electrons end up following the same repeating path.

Scars of Chaos: Visualizing Mysteries in Graphene Dots probabilities cluster along the paths of unstable orbits from their classical counterparts. These scars, while predicted, have remained elusive to direct observation—until now.

Using an innovative combination of graphene dot fabrication and advanced wavefunction mapping via scanning tunneling microscopy, researchers captured stunning images of scars. Within stadium-shaped GQDs, they observed striking lemniscate (∞-shaped) and streak-like probability patterns. These features recur at equal energy intervals, aligning with theoretical predictions for relativistic scars—a fascinating blend of mechanics and relativity.

The researchers further confirmed that these patterns are connected to two specific unstable periodic orbits within the GQD, bridging the chaotic motion of classical systems with the world. Beyond providing the first visual proof of scarring, this work lays the foundation for exploring other exotic scar phenomena, such as those induced by perturbations, chirality, or antiscarring effects.

China: Ampace’s cylindrical lithium battery charges 80% in 10 minutes

A China-based firm has launched a novel energy storage device that tackles the 18650-battery power challenge. Introduced by Ampace, the latest JP30 cylindrical lithium battery is claimed to be capable of delivering breakthrough performance in a compact form.

Themed “Working Non-stop, compact and more powerful”, the new battery is the latest addition to the JP series.

Despite having a compact and sleek design in appearance, the battery offers ultra-high power performance.

EV charging infrastructure isn’t just for road trippers

That means digging all the trenching and building out all the electrical distribution equipment on site, if not all the chargers, with a microgrid that’s capable of working as well in the future with 12 MW of power as it does with just 4 MW.

“I think this is the same challenge that all of these large sites are facing—it takes an extremely long time to get the power from the utility. Meanwhile, you don’t need it immediately. So how do you create this sort of staged future-proof solution where you’re not having to open the roads multiple times? You want one construction phase and you want that site to support the future demand,” Putignano said.

For fleets that need their own private charging infrastructure, there are other things to think about, too. Energy management solutions are as important here—microgrids as well as battery storage and battery-buffered chargers will play an important role, for example. But not every energy management solution is charger-agnostic, and the collapse of charger manufacturers like Juicebox and Tritium highlight the perils of being stuck in a walled garden belonging to a dead company.

Unlocking the Sun’s Fiery Secrets: NASA’s PUNCH Mission Set for Early 2025 Launch

Launching in February 2025, NASAs PUNCH mission will study the Sun’s corona and solar wind with four satellites.

NASA and SpaceX plan to launch NASA’s PUNCH mission (Polarimeter to Unify the Corona and Heliosphere) in late February 2025 aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

The PUNCH mission consists of four small satellites designed to enter low Earth orbit and capture 3D, global views of the Sun’s corona. By studying how mass and energy in the corona become the solar wind, scientists hope to gain new insights into solar activity and its effects on space weather.

BYD delivers 600 MWh of batteries for solar-plus-storage project in Chile

Grenergy, a Spanish independent power producer focused on the development of PV, wind, and energy storage projects, has announced the arrival of 105 BYD batteries at the port of Iquique, Chile.

Grenergy said that the Chipol Guangan cargo ship, arriving after a 42-day journey from Dachan, China, has delivered 1,050 MC Cube ESS battery modules with a total storage capacity of 600 MWh. The modules will support the Oasis de Atacama solar-plus-storage project in Chile.
