Chen Ning Yang, one of the world's most renowned physicists and a Nobel Prize winner, died at 103 of illness in Beijing on October 18, state news outlet Xinhua said on Saturday.

Scientists have filmed nanoscale ice crystals adapting to trapped air bubbles without losing structural integrity.

A descoberta traz implicações de longo alcance, do entendimento do ciclo da água e do clima da Terra até a segurança da aviação.

Significant advances in science and engineering often emerge at the intersections of disciplines. Nanoscience and nanotechnology are inherently interdisciplinary, uniting researchers from chemistry, physics, biology, medicine, materials science, and engineering. This convergence has fostered novel ways of thinking and enabled the development of materials, tools, and technologies that have transformed both basic and applied research, as well as how we address critical societal challenges. In this Nano Focus, we pose and explore 33 questions whose answers could profoundly impact fields such as energy, electronics, the environment, optics, and medicine. These questions highlight the need for deeper foundational understanding, improved tools and techniques, and innovative applications─each with significant societal relevance. Together, they represent a global call-to-action for the scientific community.
