The latest focal S:N501 build is now up! It includes data from 4 Jan 2021.
We have new sequences in 501Y.V1/B.1.1.7 from Denmark, Singapore, Australia, Italy, Spain, France, Portugal, Germany, Brazil, Jamaica, Luxembourg, Pakistan & the USA.

Zooming in (divergence view) on the California cluster, the relationship between these samples is difficult to infer from phylogenies alone.

Though hard to see on the larger tree, the 2 Pakistan sequences sit apart on the phylogeny, & thus indicate separate introductions.

Lots of tweets about this today!
Let's see what we can see in the focal S:E484 build!
Phylogenetics (what I do - making 'family trees' from virus genetics) can be very informative to see how different variants are spreading, and how cases
There are two variants circulating predominantly in Brazil:
- 20B/S.484K seems to be older & more widespread. It has (among others) a mutation at position 484
- 20J/501Y.V3 is smaller & detected recently. It has mutations at 501 *and* 484.

The variant predominantly in the UK (501Y.V1 / B.1.1.7) and the variant predominantly in South Africa (501Y.V2) also both have 501. 501Y.V2 *also* has the 484K mutation.
Why are there concerns about these mutations? You can read more at https://t.co/wVE7ubYBoy!

The view below is from an analysis focusing on sequences with a mutation at 484. It shows all the samples in the 2 variants (20B/S.484K & 20J/501Y.V3) & how they're related. More closely related = closer together (very, very roughly).
4/10
We can colour these samples by region to see where they're from. As we expect - most are in Brazil! A few are in Argentina (also red).

A few thoughts on this sad development 👇👇
20 academics criticizing an paper is fine; good science, really
10000+ hate mail for studying schools in Sweden is insane
Anonymous docs/ prof (hiding in faceless accts) on twitter smearing researchers is insane
[thread] https://t.co/QYldLD3WO0
In April 2020, @jflier and I saw this coming
We saw increasingly heated and personal attacks against scientists merely for having a range of views on COVID19 (PS there is no playbook/ right ans)
Tying science to naked politics was also bad idea, we
Yet, repeatedly that is what happened. Twitter 'experts' displayed an absolute intolerance to other views
Folks who disagreed weren't just wrong, they were malicious actors spreading "disinformation"
Really? Someone worked for 25 years as faculty to suddenly spread lies?
Disinformation has been so misused that it has lost meaning.
I recently saw an ID doc & lab researcher in the UK be accused of spreading "disinformation"
hahah, get outta here, you are trying to say "i disagree" but your keyboard is broken
Personal attacks have become so bad that I have seen a lab researcher accuse a doctor of wanting to engage in inappropriate relationships with patients due to diverging views on vaccine messaging
Seriously? It was a low point even for twitter

Together with @ernkrans, I am interviewed in @bmj_latest: "We need to ensure that our researchers understand the concept and value of academic freedom and the responsibility that comes with it"https://t.co/AFjtbSfgjr

Scholars believe word’s origin in Vedas,known as Swasti mantra;
"🕉स्वस्ति ना इन्द्रो वृधश्रवाहा
स्वस्ति ना पूषा विश्ववेदाहा
स्वस्तिनास्तरक्ष्यो अरिश्तनेमिही
स्वस्तिनो बृहस्पतिर्दधातु"
It translates to," O famed Indra, redeem us. O Pusha, the beholder of all knowledge, redeem us. Redeem us O Garudji, of limitless speed and O Bruhaspati, redeem us".
SWASTIK’s COSMIC ORIGIN
The Swastika represents the living creation in the whole Cosmos.
