1. I find it remarkable that some medics and scientists aren’t raising their voices to make children as safe as possible. The comment about children being less infectious than adults is unsupported by evidence.

2. @c_drosten has talked about this extensively and @dgurdasani1 and @DrZoeHyde have repeatedly pointed out flaws in the studies which have purported to show this. Now for the other assertion: children are very rarely ill with COVID19.
3. Children seem to suffer less with acute illness, but we have no idea of the long-term impact of infection. We do know #LongCovid affects some children. @LongCovidKids now speaks for 1,500 children struggling with a wide range of long-term symptoms.
4. 1,500 children whose parents found a small campaign group. How many more are out there? We don’t know. ONS data suggests there might be many, but the issue hasn’t been studied sufficiently well or long enough for a definitive answer.
5. Some people have talked about #COVID19 being this generation’s Polio. According to US CDC, Polio resulted in inapparent infection in more than 99% of people. Severe disease occurred in a tiny fraction of those infected. Source: https://t.co/Wpfrk9qsHJ
6. In the US, the peak of severe disease came in 1952 when over 20,000 people in the US suffered paralysis. As this fascinating case report shows, mild illness as a child could be followed by severe complications many years later.

7. Did people focus only on the 99% who survived the disease? Did people seek to minimise the experiences and suffering of the unlucky few? No. The world came together to eradicate the disease. I’m not suggesting #COVID19 is as serious as Polio.
8. But I am saying there are many unanswered questions. Polio didn’t burst onto the scene. It took decades for the disease to reach its peak & for scientists to properly understand it. We’ve been living with COVID19 for less than a year. It seems cavalier to dismiss risk.
9. It also shows a lack of empathy to sideline parents who are struggling to understand what’s happening to their children. Until there is good data on prevalence of #LongCovid in children and evidence that explains the mechanisms of the condition, risk cannot be quantified.
10. And I say mechanisms because possible explanations for #LongCovid could be organ damage, neuro invasion, viral persistence, or the development of autoantibodies. Until we understand the condition better, I’m not sure why we’d celebrate ignorance.
11. Does this mean we have to hibernate until science catches up? No. But it would seem prudent to minimise risk whenever possible. The UK is almost alone in not mandating masks in classrooms. It has not implemented many of the aerosol mitigation measures seen around the world.
12. We’re not taking reasonable steps to protect children. Steps that would also benefit the community at large by slowing transmission. If we’ve learned anything from the past year it’s that precaution is the better approach.
13. For some reason the issue of child safety has become politicised, with fringe groups arguing against safety measures adopted in almost every other developed country. If we want our schools to stay open, we need to make an effort to make them safe.
14. Reduce risk as much as reasonably possible while science catches up on a new disease and medicine vaccinates or treats the problem into irrelevance.

1. I believe the government is about to make another huge mistake. Where is @UKLabour in all this? I have some questions @Keir_Starmer should be asking urgently. Please RT to raise awareness.


2. Where is the modelling or evidence to support a focused protection vaccination strategy? The government has chosen it as its preferred strategy but it must have considered other options. Will the government publish the data and the alternative options considered?

3. A responsible government will have modelling for 20%, 50% and 80% vaccine coverage, and projections for the number of infections, Long Covid and deaths in each scenario. Where are those models? On what basis has the government opted for the 20% scenario?

4. The government should also have modelled each of these scenarios against a backdrop of low, medium and high community transmission. What is the impact of each vaccination scenario against varying levels of community transmission?

5. There should also be some assessment of incidence of reinfection and likely evolution of variants given different levels of community transmission. What does this assessment tell us?
1. This thread has been given a new lease of life today. People keep saying, "We can't do #ZeroCovid, it doesn't fit with our way of life."

Look around.

What way of life?

The one we used to have?

The UK has been under varying degrees of restriction since March 23rd 2020.


2. Nearly a year of having our social and economic freedoms curtailed in one way or another. Nearly a year of muted economic activity. Nearly a year of mass death and disease.

#ZeroCovid doesn't fit with a way of life that doesn't exist anymore.

3. The question isn't whether it fits with our old freewheeling ways, but whether it would lead to better outcomes than the UK's current (poorly defined) strategy? Experiences in New Zealand, Australia, Vietnam, China, Taiwan and elsewhere very much suggest it would.

4. #ZeroCovid isn't about what's possible. It's about what's necessary. Decide what's necessary and figure out a way to make it possible. We can't force travellers to quarantine in hotels for two weeks? Why not? Taiwan does. And if that's what's necessary, why aren't we doing it?

5. I've heard some odd things said about #ZeroCovid

Simple-minded clod Matt Hancock said Zero Covid is impossible because no country has had zero cases.

Zero Covid sets out an ambition. It signals a country treats any infections as serious
1. The problem facing Europe & the US isn't a scientific one. Scientists have been clear for months: public health and economic & social wellbeing are best served by policies that supress the virus. The #JohnSnowMemo cites evidence that makes this

2. Some media commentators seek to present the issue of how to respond to the virus in simplistic terms: Lockdown vs Herd Immunity. This a mischaracterisation. The countries that have tackled #COVID-19 best have used a range of public health


3. Almost every scientist acknowledges lockdown equals failure. It is a sign governments have failed to implement the measures needed to allow life to be lived more or less as normal, without risking exponential growth in transmission.

4. There is an active misinformation campaign that is being aided and abetted by certain sections of the media and some politicians. The campaign would have us believe that if we open up and shield the vulnerable, all will be well. This approach has been derided as inhumane...

5. ...by the WHO, and ridiculous by Dr Fauci for many reasons. It is based on faulty logic, and the proponents of this approach have submitted no evidence that it can be achieved nor any practical examples of how they would do so.

In some cases, almost 100% of the light energy can be converted to the second harmonic frequency. These cases typically involve intense pulsed laser beams passing through large crystals, and careful alignment to obtain phase matching.

क्या आप जानते हैं कि क्या है, पितृ पक्ष में कौवे को खाना देने के पीछे का वैज्ञानिक कारण!

श्राद्ध पक्ष में कौओं का बड़ा ही महत्व है। कहते है कौआ यम का प्रतीक है, यदि आपके हाथों दिया गया भोजन ग्रहण कर ले, तो ऐसा माना जाता है कि पितरों की कृपा आपके ऊपर है और वे आपसे ख़ुश है।


कुछ लोग कहते हैं की व्यक्ति मरकर सबसे पहले कौवे के रूप में जन्म लेता है और उसे खाना खिलाने से वह भोजन पितरों को मिलता है

शायद हम सबने अपने घर के किसी बड़े बुज़ुर्ग, किसी पंडित या ज्योतिषाचार्य से ये सुना होगा। वे अनगिनत किस्से सुनाएंगे, कहेंगे बड़े बुज़ुर्ग कह गए इसीलिए ऐसा करना

शायद ही हमें कोई इसके पीछे का वैज्ञानिक कारण बता सके।

हमारे ऋषि मुनि और पौराणिक काल में रहने वाले लोग मुर्ख नहीं थे! कभी सोचियेगा कौवों को पितृ पक्ष में खिलाई खीर हमारे पूर्वजों तक कैसे पहुंचेगी?

हमारे ऋषि मुनि विद्वान थे, वे जो बात करते या कहते थे उसके पीछे कोई न कोई वैज्ञानिक कारण छुपा होता था।

एक बहुत रोचक तथ्य है पितृ पक्ष, भादो( भाद्रपद) प्रकृति और काक के बीच।

एक बात जो कह सकते कि हम सब ने स्वतः उग आये पीपल या बरगद का पेड़/ पौधा किसी न किसी दीवार, पुरानी

इमारत, पर्वत या अट्टालिकाओं पर ज़रूर देखा होगा। देखा है न?

ज़रा सोचिये पीपल या बरगद की बीज कैसे पहुंचे होंगे वहाँ तक? इनके बीज इतने हल्के भी नहीं होते के हवा उन्हें उड़ाके ले जा सके।
1/“What would need to be true for you to….X”

Why is this the most powerful question you can ask when attempting to reach an agreement with another human being or organization?

A thread, co-written by @deanmbrody:


2/ First, “X” could be lots of things. Examples: What would need to be true for you to

- “Feel it's in our best interest for me to be CMO"
- “Feel that we’re in a good place as a company”
- “Feel that we’re on the same page”
- “Feel that we both got what we wanted from this deal

3/ Normally, we aren’t that direct. Example from startup/VC land:

Founders leave VC meetings thinking that every VC will invest, but they rarely do.

Worse over, the founders don’t know what they need to do in order to be fundable.

4/ So why should you ask the magic Q?

To get clarity.

You want to know where you stand, and what it takes to get what you want in a way that also gets them what they want.

It also holds them (mentally) accountable once the thing they need becomes true.

5/ Staying in the context of soliciting investors, the question is “what would need to be true for you to want to invest (or partner with us on this journey, etc)?”

Multiple responses to this question are likely to deliver a positive result.
So the cryptocurrency industry has basically two products, one which is relatively benign and doesn't have product market fit, and one which is malignant and does. The industry has a weird superposition of understanding this fact and (strategically?) not understanding it.


The benign product is sovereign programmable money, which is historically a niche interest of folks with a relatively clustered set of beliefs about the state, the literary merit of Snow Crash, and the utility of gold to the modern economy.

This product has narrow appeal and, accordingly, is worth about as much as everything else on a 486 sitting in someone's basement is worth.

The other product is investment scams, which have approximately the best product market fit of anything produced by humans. In no age, in no country, in no city, at no level of sophistication do people consistently say "Actually I would prefer not to get money for nothing."

This product needs the exchanges like they need oxygen, because the value of it is directly tied to having payment rails to move real currency into the ecosystem and some jurisdictional and regulatory legerdemain to stay one step ahead of the banhammer.
