First Electron Microscope Image of DNA Double Helix

dna-double-helix

The structure of DNA was originally discovered by using X-ray crystallography, which involves scattering X-rays off atoms in crystallized arrays of DNA to form complex patterns of dots on photographic film. Images were then interpreted using complex mathematics. These new images are now direct pictures of DNA strands, seen through an electron microscope, which sees electrons rather than photons.

Molecular Nano-Machine Assembly Mimics Human Muscle Movement

artificial-molecular-muscle

An assembly of thousands of nano-machines has been put together to produce a coordinated contraction movement, extending up to ten centimeters, akin to the movement of muscular fibers. They were synthesized by a CNRS research team from the Institut Charles Sadron.
