Spatiotemporal resolution in high-speed atomic force microscopy for studying biological macromolecules in action
TL;DR: In this paper , the authors explain the principle of high-speed atomic force microscopy (HS-AFM) and describe how the resolution is determined, and discuss recent attempts to improve the resolution of HS-AFMs to further extend the observable range of biological phenomena.

Removing the parachuting artifact using two-way scanning data in high-speed atomic force microscopy
TL;DR: Wang et al. as mentioned in this paper developed a computational method to detect and remove the parachuting artifact in high-speed atomic force microscopy (HS-AFM) images using the two-way scanning data.
Kinetochore-microtubule attachment in human cells is regulated by the interaction of a conserved motif of Ska1 with EB1
Renjith M. Radhakrishnan,Safwa Thekke Kizhakkeduth,Vishnu M. Nair,Shine Ayyappan,R. Bhagya Lakshmi,Neethu Maria Babu,Anjaly Prasannajith,K. Umeda,Vinesh Vijayan,Noriyuki Kodera,Tapas Manna +10 more
TL;DR: This paper showed that EB1-mediated Ska1 recruitment onto the microtubule serves as a general mechanism for the formation of vertebrate kinetochore-microtubule attachments and metaphase chromosome alignment.
