Scientists use FAST to analyze FRB 20201124A and discover 90% circular polarization, a record high. The findings contradict theoretical models, suggesting pulsar-like mechanisms may be more plausible.
A study discovers that traditional Chinese ice-ray lattice designs can provide unique stiffness and strength under asymmetric loads, offering an alternative to conventional gridshells. The research also explores the potential of integrating complex geometry into facade design and micro-scale material design.
A team of archaeologists has found evidence of intentionally crafted limestone spheroids at the Ubeidiya site, dating back 1.4 million years. The discovery challenges existing beliefs about early hominin capabilities and technological achievements, suggesting a desire for symmetrical shapes in stone.
Researchers at Duke University have developed a simplified method to calculate the attractive forces between nanoparticles, allowing for faster simulations and potentially leading to breakthroughs in fields like solar energy and catalysis. The new approach has been shown to be accurate within 8% of the actual results.
Scientists at the Institute for Basic Science successfully synthesized a large organic cage composed of multi-porphyrin units without using templates. The P12L24 cage has a truncated cuboctahedral structure and an inner cavity diameter of 4 nm, making it suitable for encapsulating large guest molecules.
Researchers at Tokyo Institute of Technology have demonstrated that special tetrahedron nanostructures composed of certain metals can exhibit a higher degree of symmetry than spherical atoms.
