A new study has uncovered the universal dynamics far from equilibrium in randomly interacting spin models, thereby complementing the well-established universality in low-energy equilibrium physics. The study, recently published in Nature Physics, was the result of a collaborative effort involving the research group led by Prof. Du Jiangfeng and Prof. Peng Xinhua at the University of Science and Technology of China (USTC), along with the theoretical groups of Prof. Zhai Hui from Tsinghua University and Dr. Zhang Pengfei from Fudan University.

A plasma jet from galaxy M87 appears to move five times faster than light.

In the world of astronomy, a peculiar and seemingly impossible phenomenon is unfolding in galaxy M87. A beam of plasma, or energy, is shooting out from the galaxy’s core and appears to travel at five times the speed of light, as observed by the Hubble Space Telescope. Though this illusion has been known since 1995, it continues to challenge our understanding of the universe’s laws, particularly the cosmic speed limit that states nothing can move faster than light.

A new technique for harvesting geothermal energy being pioneered in Utah has passed a significant milestone: Southern California Edison has contracted for enough of the energy to power 400,000 homes.

Instead of needing constant power, new system adjusts to use whatever’s available.

The Tewksbury earthquake’s minimal local damage but widespread impact was due to its rupture direction, funneling shaking from New Jersey towards New York City, with the anomaly highlighted in studies on seismic energy distribution.

A magnitude 4.8 earthquake in Tewksbury startled millions across the U.S. East Coast, marking the strongest recorded tremor in New Jersey since 1900.

But researchers noted something else unusual about the earthquake: why did so many people 40 miles away in New York City report strong shaking, while damage near the earthquake’s epicenter appeared minimal?

A flow battery, also known as a reduction-oxidation (Redox) flow battery, is an electrochemical cell that uses two moving liquid electrolytes to generate electricity.

Ion transfer occurs across the cell membrane, accompanied by current flow through an external circuit, while the liquids circulate in their respective spaces. The liquids required are stored in separate tanks until required.

As electricity was being restored in parts of Cuba following an island-wide blackout, a total collapse of the electrical grid occurred once again.

A team from Lawrence Livermore National Laboratory, Stanford University and the University of Pennsylvania introduced a novel wet chemical etching process that modifies the surface of conventional metal powders used in 3D printing.

In a significant advancement for metal additive manufacturing, researchers at Lawrence Livermore National Laboratory (LLNL) and their academic partners have developed a groundbreaking technique that enhances the optical absorptivity of metal powders used in 3D printing.

The innovative approach, which involves creating nanoscale surface features on metal powders, promises to improve the efficiency and quality of printed metal parts, particularly for challenging materials like copper and tungsten, according to researchers.
