Better classi昀椀cation with machine learning Researchers from the SNI network have presented a new ma- chine learning technique speci昀椀cally designed to enhance the analysis of protein unfolding using atomic force microscopy (AFM) data. The method is characterized by the fact that the program used repeatedly analyzes the data and thereby allows more precise and e昀케cient data classi昀椀cation. SNI post: https://bit.ly/3UQ4QTA Original publication: https://pubs.acs.org/doi/10.1021/acs.nanolett.3c03026 TBTAP molecules on a silver surface are initially negatively charged. If a positive voltage is applied to the tip of an STM and this is then brought close to the molecule, the molecule discharges. This discharge does not oc- cur in one go, but rather in an oscillating manner.
