"ESA Develops Innovative 3D-Printed Bend-Based Mechanism"

A 3D-printed frictionless gear mechanism, designed as a compliant mechanism, has been developed to enable precise rotation in space applications. The mechanism, made of high-performance stainless steel, incorporates 24 bendable blades to reduce turning force and allow fine control of rotary motion. This innovative design eliminates the need for lubrication, reducing the risk of contamination and wear and tear. The mechanism was developed by CSEM in Switzerland and tested by Almatech SA as part of an ESA Technology Development Element activity.

EPFL researchers achieve extreme DNA resolution through controlled single-molecule translocations.

EPFL researchers have combined nanopore technology with scanning ion conductance microscopy to achieve near-perfect control over the manipulation of individual molecules, allowing them to be identified and characterized with unprecedented precision. The innovation, called scanning ion conductance spectroscopy (SICS), slows molecule transit through the nanopore, allowing thousands of consecutive readings to be taken of the same molecule, and even of different locations on the molecule. The precision and versatility of this approach could be applied to molecules beyond DNA, such as protein building blocks called peptides, which could help advance proteomics as well as biomedical and clinical research.
