Scientists have confirmed that the iconic moai statues of Rapa Nui could have been moved by ancient people using a rocking, walking method with ropes, supported by experiments, 3D modeling, and analysis of the island's roads, solving a 500-year-old mystery.
American scientists at Princeton have experimentally confirmed a 200-year-old hypothesis that Earth's rotation and magnetic field can generate a tiny electric current, reviving a concept first proposed by Faraday, though practical applications remain distant due to the minuscule voltage produced and significant technical challenges.
Physicists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences have discovered a molecular-type structure in the ground state of atomic nuclei. Using a novel experimental method, they validated the presence of a molecular-type structure in the ground state of beryllium-10, a neutron-rich nucleus. The experimental results support the long-standing hypothesis of a molecular-state structure in beryllium-10's ground state, suggesting the formation of an α–α dumbbell-shaped core with two valence neutrons rotating perpendicular to the core axis. This study provides the first experimental evidence for the theoretical description of molecular-state structures in atomic nuclei's ground state.
A groundbreaking study has revealed the existence of approximately 10,000 unexplored foldable αβ-protein folds in nature, expanding our understanding of the protein universe. The research team combined theoretical prediction with experimental validation to identify 12,356 novel folds not yet observed in the Protein Data Bank. Surprisingly, computationally designed proteins closely matched the experimental structures, suggesting the potential for de novo design of functional protein molecules. These findings challenge the notion that nature has explored the full extent of protein fold space and raise hypotheses about the structure and evolution of proteins. The discovery of these uncharted protein folds could have significant implications for drug development, enzyme design, and other areas.
