Happy Tuesday! The latest focal S:N501 build is now updated with sequences from 11 Jan.
There are 101 new sequences in the 501Y.V1 (B.1.1.7 #b117) & 501Y.V2 variants.

Additionally, I'll include some updates on S:E484K in this thread.

There are 97 new non-UK sequences in 501Y.V1, including the first sequences in the cluster from Slovakia, Mexico, & Belgium, plus additional sequences from the Netherlands, Denmark, Australia, Spain, Ireland, & Sweden.

2/20
Slovakia has 10 sequences that fall in 501Y.V1 for the first time. These are closely linked, & likely indicate a single introduction and ongoing transmission (remember: vertical distance is not meaningful on the same branch - position of the 2 English samples is arbitrary).

3/20
Belgium has 5 sequences in 501Y.V1 for the 1st time, indicating 3 separate intros. 3 seqs cluster together (zoomed, divergence), indicating a single introduction. The connection to Netherlands might indicate transmission, or 2 transmissions from same diversity in the UK.

4/20
Mexico also has a sequence that falls into 501Y.V1 for the first time.

5/20
Ireland has 36 new sequences. Many represent separate introductions, but some do cluster with older sequences & may represent local transmission, or introductions from the same UK diversity.

6/20
Denmark has 29 new sequences (orange). These represent both new introductions, and further expansion of the large cluster (zoomed view).

7/20
The Netherlands have 6 new sequences. All fall within the section of the tree marked in red.
Zooming in, the new sequences are marked in red: 2 are separate introductions. Zooming in further (divergence view), cluster at the top are identical to an older sequence.

8/20
Australia has 6 new sequences, including the first from Northern Territory and Victoria. 1 pair of sequences from Victoria are identical to each other, representing one introduction.

9/20
Spain has 2 new sequences (yellow). One represents a separate introduction. The other links to older Spanish sequences, but it's unclear from sequences alone if this is local transmission or transmissions from a common source.

10/20
Sweden has 2 new sequences, marked in red. Both represent independent introductions. The second one is hard to see, but zooming in shows this more clearly.

11/20
Now turning to 501Y.V2:

There are 4 new non-South African sequences in 501Y.V2, including the first from Ireland (3) and the Netherlands (1).

12/20
Ireland has 3 sequences in 501Y.V2 for the first time. They cluster together, and may indicate either local transmission, or a common exposure (pictures 1 & 2).

The Netherlands has its first sequence in 501Y.V2 (picture 3).

13/20
As usual, the updated country graphs are also available. As always, interpret with care: countries are selectively sequencing to track 501Y.V1, so proportions of sequences are not representative for many countries.

Finally, an updated focal S:E484 build is also up.

S:E484K is found predominantly in the 501Y.V2 variant, & in a cluster of sequences primarily in Brazil, though it has appeared numerous times in the past.

S:E484K has been discussed recently as there are suggestions it may impact how well the immune system can recognise the virus, particularly if you've been infected with SARS-CoV-2 before.

16/20
Additionally, over the weekend, travellers from Brazil to Japan were found to be infected with a novel variant with many mutations, including S:E484K & S:N501Y.

To help viewers identify these new samples from Japan, I've added a *temporarily* label to the S:E484K build: 20B/S.484K.501Y.

Additionally, I've added a *temporary* label to the Brazilian cluster with S:E484K: 20B/S.484K.

18/20
Interestingly, though the recent Japanese sequences carry S:E484K & seem to originate from Brazil, they do *not* branch from the larger 484K cluster in Brazil, but instead sit on a long branch separately within the 20B Clade.

19/20
Getting case numbers down saves #LivesAndLivelihoods, and reduces #SARSCoV2's opportunities to explore situations with unique selection pressures, potentially resulting in mutations expanding that we'd rather not see.

Help make my updates more boring: bring cases down!

20/20
PS - For related but slightly-different-angle updates on 501Y.V1 (B.1.1.7) & 501Y.V2 (B.1.351), you should follow @AineToole & keep an eye on her tweets about updated reports!

This response to my tweet is a common objection to targeted advertising.

@KevinCoates correct me if I'm wrong, but basic point seems to be that banning targeted ads will lower platform profits, but will mostly be beneficial for consumers.

Some counterpoints 👇


1) This assumes that consumers prefer contextual ads to targeted ones.

This does not seem self-evident to me


Research also finds that firms choose between ad. targeting vs. obtrusiveness 👇

If true, the right question is not whether consumers prefer contextual ads to targeted ones. But whether they prefer *more* contextual ads vs *fewer* targeted

2) True, many inframarginal platforms might simply shift to contextual ads.

But some might already be almost indifferent between direct & indirect monetization.

Hard to imagine that *none* of them will respond to reduced ad revenue with actual fees.

3) Policy debate seems to be moving from:

"Consumers are insufficiently informed to decide how they share their data."

To

"No one in their right mind would agree to highly targeted ads (e.g., those that mix data from multiple sources)."

IMO the latter statement is incorrect.

THE MEANING, SIGNIFICANCE AND HISTORY OF SWASTIK

The Swastik is a geometrical figure and an ancient religious icon. Swastik has been Sanatan Dharma’s symbol of auspiciousness – mangalya since time immemorial.


The name swastika comes from Sanskrit (Devanagari: स्वस्तिक, pronounced: swastik) &denotes “conducive to wellbeing or auspicious”.
The word Swastik has a definite etymological origin in Sanskrit. It is derived from the roots su – meaning “well or auspicious” & as meaning “being”.


"सु अस्ति येन तत स्वस्तिकं"
Swastik is de symbol through which everything auspicios occurs

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.

"I really want to break into Product Management"

"If only someone would tell me how I can get a startup to notice me."

Make Products.

"I guess it's impossible and I'll never break into the industry."

https://t.co/TgNblNSCBj – here is why the same applies to Product Management, too.


There is no better way of learning the craft of product, or proving your potential to employers, than just doing it.

You do not need anybody's permission. We don't have diplomas, nor doctorates. We can barely agree on a single standard of what a Product Manager is supposed to do.

But – there is at least one blindingly obvious industry consensus – a Product Manager makes Products.

And they don't need to be kept at the exact right temperature, given endless resource, or carefully protected in order to do this.

They find their own way.
