The cor*na hoax thread. How and why, best as I can tell. First, how does the new virus work? The vast majority of cases are asymptomatic or indistinguishable from the common cold. A small minority of cases affect the lungs. But how it does should be clarified...

🚨New lockdown regulations just published, in force tomorrow
The Health Protection (Coronavirus, Restrictions) (No. 3) and (All Tiers) (England) (Amendment) Regulations 2021
https://t.co/L5jwlTDaIE
(Thread)
These are not a new set of regulations: they are amendments an old set of regulations
Which we thought were gone! But they are back
Welcome back No.3 regulations
A quick thing before we continue!
I have been analysing these laws for free for 9 months now - if you want to say thanks and have a few £ to spare please give to my @LawCentres fundraiser
They give free legal advice to people who need it
They also amend the All Tiers regulations
Oh god it's all amendments by paragraph references
Basically all of England now in Tier 4 and Tier 4 is amended but not by a huge amount
This really is a terrible way to make laws on the fly - who can possibly understand it?!
So, to explain, you need 2 documents open if you want to understand what is going on:
All Tiers regulations (Tiers 1-4, 2 December as amended) https://t.co/IraPQ112ak
And amendments https://t.co/L5jwlTDaIE
No sensible way of doing except by track changes, on it now, back soon

No-regret #hydrogen:
Charting early steps for H₂ infrastructure in Europe.
👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em
The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)
Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)
Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)
In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)

Now you know I love to sh-t in Harvard. But I also like accuracy. So I decided to go look at Harvard’s catalog to see its lack of military history that this article describes (they only teach history of pets it claims) and what I found shocked me! Shocked me! A thread: 1/
First off, Harvard students literally have multiple sections of military history that they can take listed. (It appears these ones are taught at MIT, so they might have to walk down the street for these) but... 2/
Say they want to stay on campus...they can only take numerous classes on war and diplomacy...3/
They have an entire class on Yalta. That’s right. An entire class on Yalta. 4/
But wait! There is more! They can take the British Empire, The Fall of the Roman Empire for those wanting traditional topics... 5/
\u201cMilitary history\u201d is only in decline if you\u2014like the author & experts in this obnoxious piece\u2014see the subject as a narrowly defined, white dude-oriented, guns & bayonets approach. The field is 1000% better off w/today\u2019s diversity of topics & historians. https://t.co/dUf3OWyVpQ

Sarcomeres in cardiac myocytes (heart muscle cells) are mechanically coupled to focal adhesions through dorsal stress fiber-like structures. #cardiotwitter #CellBiology
1/13
A thread based on Figure 1
A mature adult cardiac myocyte is packed with sarcomeres, whose contractile forces are coupled to the extracellular environment. With sarcomeres so close to the plasma membrane, how can we study the nature of this coupling?
2/13
Short answer: find a model system where the sarcomeres are not so close to what the cardiac myocyte is attached to. Enter, iPS cell-derived cardiac myocytes. These are “immature” in culture as they resemble fetal or neonatal cardiac myocytes.
3/13
Our previous work on iPS cardiac myocytes reported that sarcomere containing myofibrils assembled on the top surface of the myocyte.
https://t.co/xIBCu3hG1W
4/13
The sarcomeres seemed to be connected to focal adhesions on the bottom of the cell by thin actin bundles that resembled the dorsal stress fibers (DSF) commonly found in non-muscle cells. This movie steps through a Z stack of a myocyte starting at the bottom of the cell.
