"Guinness Record: Scientists Create World's Tiniest Knot with 54 Atoms"
Scientists accidentally created the world's smallest and tightest knot, consisting of just 54 atoms and resembling a trefoil with three interlaced crossings and no loose ends. The "metallaknot" contains gold and self-assembles, breaking the previous record for tightest knot with a backbone-to-crossing ratio of 23. This discovery could have implications for understanding molecular structures in DNA, RNA, and proteins, as well as potential applications in materials science and medicine.
