Exciting news - there was a bit of a nanotech new lull after the protein folding development. Speaking of which, seems the alphafold has gone quiet.

"As of 5 March 2021, DeepMind has not made any code for AlphaFold 2 publicly available to researchers. Four months after announcing the CASP14 results, the company website states: "We’re right at the beginning of exploring how best to enable other groups to use our structure predictions, alongside preparing a peer-reviewed paper for publication." - alphafold wiki.

As you know, there's many pathways to Drexlerian nanotech - protein folding, S.T.M.s, electron microscopes(Richard Feynman's idea), and DNA. Just when you want to count out DNA, there's a new exciting development.

- I got these two recently,

Scaling up DNA Origami Lattice Assembly - https://chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/chem.202100784

"At total DNA costs of €0.12 per cm², this large‐scale nanopatterning technique holds great promise for the fabrication of functional surfaces"

A synthetic tubular molecular transport system - https://www.biorxiv.org/content/10.1101/2021.03.22.436416v1

"The pistons can cover micrometer distances in fractions of seconds. . . . Electric fields can also be employed to actively pull the pistons along the filaments, thereby realizing a nanoscale electric rail system. . . . and it could form a basis for future molecular transportation networks."

The first DNA nanotech news, Scaling up DNA Origami Lattice Assembly, not only has a macroscale construct by means of DNA-nanotech, but it allows them to be able to orient nano-machines and parts and such. Previously, they could place things in a particular spot, the nano-part would be facing in various directions.

- The DNA is as usual, semi-exciting, but I'm still waiting for the latest from the electron microscope guys - also the Scanning Tunneling Microscopes. They've both able to make single atom constructs. They just need to solve massive parallelism. I would think that would be easier done with electron microscopes.

CATL's sodium hybrid battery will be 30% cheaper & revolutionise the world

Very cool…but it’s Chinese. Grr. https://youtu.be/h74Xj-WWwBc?si=mgYbSTTLUxVixZQV
