Lagrange Point

Our bodies are filled with molecular and cellular machines, pumping, spinning and moving. How do tiny single molecules pump sodium ions across a cell? What is the connection between a single molecule pump and cells producing electricity? How can a single molecule pump be more efficient than our modern ones? How do we make pacemakers safer? Overtime a pacemaker grows to become part of the heart fibre. How do we make pacemakers less likely to be overgrown and easier to replace?  References:  Tatsuya Iida, Yoshihiro Minagawa, Hiroshi Ueno, Fumihiro Kawai, Takeshi Murata, Ryota Iino. Single-molecule analysis reveals rotational substeps and chemo-mechanical coupling scheme of Enterococcus hirae V1-ATPase. Journal of Biological Chemistry, 2019; 294 (45): 17017 DOI: 10.1074/jbc.RA119.008947 Francesco Robotti, Ita Sterner, Simone Bottan, Josep M.
