This week, NASA’s SPHEREx mission has captured new data on 3I/ATLAS, only the third known interstellar object, offering tantalizing insights into its unusual chemical makeup and origins. Meanwhile, at Switzerland’s University of Basel, researchers unveiled a breakthrough molecule capable of storing charges in a way that mimics photosynthesis, marking progress toward carbon-neutral solar fuels. And in materials science, researchers have identified the first organic “altermagnet,” a substance with exotic light-bending properties that could reshape the future of spintronics, quantum technologies, and flexible magnetic devices.
