   Richard Neher should have done some mentoring as well.

   Hah - you'd imagine him beating the Trevor out of her and replace it with physics smugness :wink:

   Oh, don't get me started...

   Back to science - we just picked up two _very_ interesting "CA" lineage viruses carrying the d144 deletion and a few other mutations, including N501Y and (more intriguingly) L455F - two out of six of the contact residues hit in a single lineage. L455F is rare - mostly seen in a few genomes from Australia. Eddie, do you have any idea if that mutation was looked into? @Robert Garry your eyes on L455F? Remember, the "CA" lineage has the L452R mutation too, so I wonder if those two together might do something funky.

   The screenshot - two bottom sequences = new genomes. Above that, "Type" B.1.429 and above that, Wuhan Hu-1.

   Can you tell me what the Australian sequences are? I'll look into it. No way that L455F will have been studied here.

   I can't... We're unfortunately not allowed to pull GISAID IDs... I can see UK has a few of the double mutants too. https://outbreak.info/situation-reports?pango&muts=S%3AN501Y&muts=S%3AL455F

   Ok, I'll ask about it.

   I'll look - any change to an aromatic amino acid could potentially set up a stronger binding.
