The instrument uses light to move atoms to measure incredibly small forces.


A new study finds that chimpanzees’ self-medication has helped scientists identify some promising plants for future pharmaceuticals. In the study, Oxford researchers have identified no less than 13 plants with potent wound-healing and infection-fighting properties.

The researchers made this astounding discovery thanks to the help of wild chimpanzees. By observing them in the wild, the team found that chimps tend to eat bark, dead wood, and leaves that are not part of their diet when sick or injured.

In a study recently published in the journal Nano Letters, researchers from Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, Kanazawa, Japan, used frequency-modulated atomic force microscopy to reveal the submolecular structure of microtubule (MT) inner surface and visualize structural defects in the MT lattice, providing valuable insights into the complex dynamic processes that regulate microtubule function.

Microtubules (MTs), a key component of the cytoskeleton in , serve as scaffolds and play vital roles in cellular processes such as , cell migration, intracellular transport, and trafficking. MTs are composed of α-tubulin and β-tubulin proteins, which polymerize into dimers and assemble into linear protofilaments that form a cylindrical lattice.

Traditional methods like X-ray crystallography and cryo– have provided structural insights into MTs but involve complex sample preparation and data analysis. There remains a need for techniques that can examine MT structural features, assembly dynamics, and lattice defects at submolecular resolution under physiological conditions.
