A research team led by Lu Haipeng, a professor in the Department of Chemistry at The Hong Kong University of Science and Technology (HKUST), has achieved a breakthrough in preserving spin information for optoelectronic technologies. The team has developed a perovskite chiral multiple quantum-well system that maintains spin polarization approximately 300 times longer at room temperature. The study opens new possibilities for future quantum technologies and next-generation spin-based applications. The study was published in the journal Nature Photonics.

The COP31 climate talks kicked off Monday with an early fight over money as the U.N.'s chief urged world leaders to "get serious" about tackling the crisis after a year of devastating weather extremes.

Scientists are predictng this could be the hottest year on record as the COP31 climate summit opens.

War, artificial intelligence and the Trump era have overshadowed climate change. But officials from nearly every nation are meeting to confront global warming.

Researchers at Kanazawa University and the National Institute of Genetics in Japan have used high-speed atomic force microscopy to observe how a group of proteins known as Smc5/6 interacts with DNA. The images reveal how this structure opens and closes, captures DNA and brings separate sections together. The researchers also observed Smc5/6 holding twisted sections of DNA in place, producing more tightly packed arrangements. The findings, published in Nature Communications, provide new insights into the molecular processes that contribute to the maintenance and repair of genetic material.

How atoms are arranged inside materials can influence the behavior of electrons and the resulting electronic states. Kagome lattices, repeating arrangements of atoms forming triangles that share corners (with hexagonal spaces between them), have been linked with the emergence of unusual electronic states.
