Science journal issues correction for study on twist buckling in metamaterials

The scientific journal Nature has published a formal author correction regarding a previously released study on chiral metamaterials and twist buckling. The original paper was first published online on March 12, 2025. According to the update, the researchers used an incorrect formula to normalise a force calculation in the initial work. Specifically, the team used a single length term in the denominator instead of a squared length term. This error changed the y-axes on several visual figures, including Figure 2 and multiple Extended Data figures. It also changed a numerical value in the text on rod buckling from 0.8 to 24 for a chiral rod with a radius of 6 millimetres and an initial angle of 5 degrees. The updated figures and text values have now been multiplied by 30 to fix the mistake. Another error was found in the Methods section regarding the typed expression for Delta out, where a power of four was mistakenly used instead of a squared term. The authors state that these changes do not affect the overall analyses or final conclusions of the study. Both the HTML and PDF versions of the article have been updated. The work was carried out by researchers from institutions including the National University of Defense Technology in China, the University of California, Santa Barbara, the Karlsruhe Institute of Technology, and the Fraunhofer Institute for Mechanics of Materials IWM. The correction notice itself was published online on September 23, 2026.
