Scott Alexander on the risk of ancient plagues returning

Filed under: Environment, Health, History — Tags: , , , , , , , — Nicholas @ 03:00

The other day, Scott Alexander responded to a hair-on-fire New York Magazine piece of hysteria-mongering about climate change warming up arctic zones that may still harbour ancient plagues that can return:

I’m a little nervous talking about this, because I am not a microbiologist. But I haven’t seen the proper experts address this properly, so I’ll try, and if I’m wrong you guys can shout me down.

(Also, the real microbiologists are apparently “self-injecting [3.5 million year old bacteria] just out of curiosity” and we should probably stay away from them for now)

I think we probably don’t have to worry very much about ancient diseases from millions of years ago.

Animal diseases can’t trivially become contagious among humans. Sometimes an animal disease jumps from beast to man, like COVID or HIV, but these are rare and epochal events. Usually they happen when the disease is very common in some population of animals that lives very close to humans for a long time. It’s not “one guy digs up a reindeer and then boom”.

If a plague is so ancient that it’s from before humans evolved, it’s probably not that dangerous. In theory, it could be dangerous for whatever animal it originally evolved for — a rabbit plague infecting rabbits, or an elephant plague infecting elephants. And then maybe after many rabbits are infected, some human might eat an infected rabbit and get unlucky, and the plague might mutate to affect humans. But I don’t think this is any more likely than any of the zillion plagues that already infect rabbits jumping to humans, and nobody is worrying about those.

The story about anthrax is a distraction. The fact that someone got anthrax from a corpse frozen in permafrost is irrelevant; there is anthrax now, and you could get it from a perfectly fresh corpse or living animal if you wanted. It’s adapted to animals and it can’t spread from person to person. Just because you got an irrelevant-to-humans modern animal disease when you dug up a modern animal, doesn’t mean you’re going to get a dangerous-to-humans disease from an ancient animals.

But I’m more concerned about recent human plagues coming back.

Not bubonic plague; that one is another distraction. The reason we don’t get more Black Deaths isn’t because yersinia pestis died off or mellowed out. It’s because we have good sanitation and pest control.

And doctors whose knowledge of medicine doesn’t begin and end with “look like a creepy bird”

But the 1918 Spanish flu has, as far as I know, legitimately died out. Lots of people like saying that in a sense it’s still with us. This NEJM paper (with a celebrity author!) points out that it’s the ancestor of all existing flu strains. But most of these flu strains are less infectious than it was. This didn’t make sense to me the first, second, or third time I asked about it: why would a flu evolve into an inferior flu? Sure, it might evolve into a less deadly flu because it’s perfectly happy being more infectious but less deadly. But I think the Spanish flu was also especially infectious; so why would it evolve away from that?

The History Guy: History Deserves to Be Remembered
Published 20 Aug 2021

On August 20, 1955, United States Air Force Colonel Horace A Hanes set the world’s first supersonic world speed record in a North American Aviation F-100C Super Sabre. Although we are well into the supersonic age, aircraft that can exceed the speed of sound are still rare machines, and marvels of engineering and pilot prowess. The early aviation pioneers who tested the terrifying sound barrier have helped scientists better understand the dynamics of superfast speeds.

In the early 1960s Canada was among the early pioneers of space technology and research. Scientists and engineers took advantage of then cutting edge technologies like the transistor and solar panels, to produce the Alouette and ISIS series of satellites. It was an immense engineering challenge that represented the high water mark of a tradition of ionospheric research that began back before the establishment of Canada as a nation. The Alouette and ISIS series of satellites produced more than 1200 research papers exploring all aspects of the Earth’s ionosphere, the aurora, and other phenomena. They also demonstrated to the world that Canada was a world leader in peaceful space technology.

Only days ahead of the French Army in April 1945, Ott-Helmuth von Lossnitzer and about 250 Mauser engineers and technicians fled Oberndorf with the core of Mauser’s new projects. They had the drawings, components, and gages for guns like the new StG-45 assault rifle, MK214 aircraft cannon, and Volkspistol and they were headed for an impregnable series of tunnels in the Austrian Alps to carry on the war. In a story that is absolutely worthy of film adaptation they scrounged a series of locomotives, dodged P47 Thunderbolt attacks, and went careening through the Alps with about 2 dozen boxcars of the most important prototype guns in the German arsenal.

Of course, the idea of continued resistance was a complete fantasy. When it did finally arrive in Ötztal, the Mauser refugees found all the tunnels already occupied by other groups with the very same idea. So they basically made camp and waited for American forces to arrive. The train was found by a British-American CIOS (Combined Intelligence Objective Subcommittee) party, the engineers were all questioned, and the train contents packed up for shipment to the UK and US. Ott-Helmuth von Lossnitzer himself emigrated to the US as part of Operation Paperclip, where he worked for Springfield Arsenal for many years until retiring in 1968 and then living in Wisconsin until his passing in 1989.

For anyone interested in this story, I highly recommend Lossnitzer’s oral recollections compiled into book form by Leslie Field and Bas Martens – ISBN 9789081737807. It is out of print now, but you may be able to find it on the secondary market.

Much more accessible is the reprinting of the original CIOS report on Mauser published by Peter Dallhammer (whom you may recall from his Textbook of Pistol Technology and Design). This is a 360-page treasure trove of details on Mauser’s ongoing R&D in 1945, and it is available on Amazon:

QotD: Biotechnology

Filed under: Environment, Politics, Quotations, Science, USA — Tags: , , — Nicholas @ 01:00

Along with rethinking cities, environmentalists will need to rethink biotechnology. One area of biotech with huge promise and some drawbacks is genetic engineering, so far violently rejected by the environmental movement. That rejection is, I think, a mistake. Why was water fluoridization rejected by the political right and “frankenfood” by the political left? The answer, I suspect, is that fluoridization came from government and genetically modified (GM) crops from corporations. If the origins had been reversed — as they could have been — the positions would be reversed, too.

Ignore the origin and look at the technology on its own terms. (This will be easier with the emergence of “open source” genetic engineering, which could work around restrictive corporate patents.) What is its net effect on the environment? GM crops are more efficient, giving higher yield on less land with less use of pesticides and herbicides. That’s why the Amish, the most technology-suspicious group in America (and the best farmers), have enthusiastically adopted GM crops.

There has yet to be a public debate among environmentalists about genetic engineering. Most of the scare stories that go around (Monarch caterpillars harmed by GM pollen!) have as much substance as urban legends about toxic rat urine on Coke can lids. Solid research is seldom reported widely, partly because no news is not news. A number of leading biologists in the U.S. are also leading environmentalists. I’ve asked them how worried they are about genetically engineered organisms. Their answer is “Not much,” because they know from their own work how robust wild ecologies are in defending against new genes, no matter how exotic. They don’t say so in public because they feel that entering the GM debate would strain relations with allies and would distract from their main focus, which is to research and defend biodiversity.

English sea-borne trade in the early 17th century

Filed under: Africa, Americas, Asia, Books, Britain, Europe, History — Tags: , , , , , , — Nicholas @ 03:00

In the latest Age of Invention newsletter, Anton Howes reviews a book on English trade … a very old book:

I’ve become engrossed this week by a book written in 1638 by the merchant Lewes Roberts — The Marchant’s Mappe of Commerce. It is, in effect, a guide to how to be a merchant, and an extremely comprehensive one too. For every trading centre he could gather information about, Roberts noted the coins that were current, their exchange rates, and the precise weights and measures in use. He set down the various customs duties, down even to the precise bribes you’d be expected to pay to various officials. In Smyrna, for example, Roberts recommended you offer the local qadi some cloth and coney-skins for a vest, the qadi‘s servant some English-made cloth, and their janissary guard a few gold coins.

Unusually for so many books of the period, Roberts was also careful to be accurate. He often noted whether his information came from personal experience, giving the dates of his time in a place, or whether it came second-hand. When he was unsure of details, he recommended consulting with better experts. And myths — like the rumour he heard that the Prophet Muhammad’s remains at Mecca were in an iron casket suspended from the ceiling by a gigantic diamond-like magnet called an adamant — were thoroughly busted. Given his accuracy and care, it’s no wonder that the book, in various revised editions, was in print for almost sixty years after his death. (He died just three years after publication.)

What’s most interesting about it to me, however, is Roberts’s single-minded view of English commerce. The entire world is viewed through the lens of opportunities for trade, taking note of the commodities and manufactures of every region, as well as their principal ports and emporia. A place’s antiquarian or religious tourist sites, which generally make up the bulk of so many other geographical works, are given (mercifully) short shrift. Indeed, because the book was not written with an international audience in mind, it also passes over many trades with which the English were not involved, or from which they were even excluded. It thus provides a remarkably detailed snapshot of what exactly English merchants were interested in and up to on the eve of civil war; and right at the tail end of a century of unprecedented growth in London’s population, itself seemingly led by its expansion of English commerce.

So, what did English merchants consider important? It’s especially illuminating about England’s trade in the Atlantic — or rather, the lack thereof.

Roberts spends remarkably little time on the Americas, which he refers to as the continents of Mexicana (North America) and Peruana (South America). Most of his mentions of English involvement are about which privateers had once raided which Spanish-owned colonies, and he gives especial attention to the seasonal fishing for cod off the coast of Newfoundland — a major export trade to the Mediterranean, and a source of employment to many English West Country farmers, who he refers to as being like otters for spending half their lives on land and the other half on sea.

But as for the recently-established English colonies on the mainland, which Roberts refers to collectively as Virginia, he writes barely a few sentences. Although he reproduces some of the propaganda about what is to be found there — no mention yet of tobacco by the way, with the list consisting largely of foodstuffs, forest products, tar, pitch, and a few ores — the entirety of New England is summarised only as a place “said to be” resorted to by religious dissenters. The island colonies on Barbados and Bermuda were also either too small or too recently established to merit much attention. To the worldly London merchant then, the New World was still peripheral — barely an afterthought, with the two continents meriting a mere 11 pages, versus Africa’s 45, Asia’s 108, and Europe’s 262.

The reason for this was that the English were excluded from trading directly with the New World by the Spanish. It was, as Roberts jealously put it, “shut up from the eyes of all strangers”. The Spanish were not only profiting from the continent’s mines of gold and silver, but he also complained of their monopoly over the export of European manufactures to its colonies there. It’s a striking foreshadowing of what was, in the eighteenth century, to become one of the most important features of the Atlantic economy — the market that the growing colonies would one day provide for British goods. Indeed, Roberts’s most common condemnation of the Spanish was for having killed so many natives, thereby extinguishing the major market that had already been there: “had not the sword of these bloodsuckers ended so many millions of lives in so short a time, trade might have seen a larger harvest”. The genocide had, in Roberts’s view, not only been horrific, but impoverished Europe too (he was similarly upset that the Spanish had slaughtered so many of the natives of the Bahamas, known for the “matchless beauty of their women”).

Justin Trudeau is clearly not concerned about China or Chinese involvement in Canadian affairs

Filed under: Cancon, China, Government, Health, Science — Tags: , , , , , — Nicholas @ 05:00

In The Line, Jen Gerson outlines the PM’s latest display of insouciance in regard to anything involving China, their ruling Communist party, or the Chinese military:

The Globe and Mail reported last week that Canada’s top infectious disease research centre, the National Microbiology Laboratory in Winnipeg, had hosted and otherwise collaborated with guest researchers and scientists from China — including some with links to that country’s military or government. O’Toole asked about this in the House, and Trudeau gave a very routine Trudeauvian non-answer. O’Toole and other Tories kept up the questioning, Trudeau eventually responded with this (as per Hansard): “Mr. Speaker, we have always and will always take this threat seriously. Public safety officials have met with more than 34 universities to help them keep their research safe. In 2020, CSIS engaged more than 225 different organizations, including universities, to ensure that they were aware of foreign threats. I also want to mention that we are seeing a disturbing rise in anti-Asian racism. I hope that my Conservative Party colleagues are not raising fears about Asian Canadians.”

Sigh. Where do we begin?

First of all, though this may shock our readers, the Sun papers, and its columnists, have been known to exaggerate their criticisms of the PM. The PM gave a more substantive answer than Lilley gave him credit for. You can disagree with the PM — see below! — without getting cute with what he actually said. The racism line was dumb, and shitty. It was beneath the PM and unfair to the legitimate questions that were being asked. Trudeau shouldn’t have said it, and he was right to get called out for it.

So yes, a dick move by the PM — in a hundred years, maybe one of his descendants can apologize for it. But let’s not take our eye off the ball.

Trudeau’s answers were more than Lilley suggested, but they’re still not good enough. O’Toole and the Conservatives are onto something. China’s ruling regime is aggressive, brutal, and thuggish. They’re a threat to security abroad, they’re committing outright crimes against humanity against their own religious minorities, they’ve crushed Hong Kong underfoot, and they’re actively hostile to Canada. None of this is racist to note.

And yet our federal Liberals remain alarmingly unable to admit any of this. We don’t buy that it’s just a matter of political expediency, an awkward but necessary consequence of the ongoing detention of the two Michaels. Hell, we wish that the Liberals were just being publicly cautious with their real views on Beijing while remaining clear-eyed about the threat behind closed doors. The evidence continues to suggest that the federal Liberals, from Trudeau on down, remain hopelessly naïve about the nature of Beijing’s rulers, even as more and more of our allies are getting real about what the next generation or two of geopolitics is gonna look like for the Western alliance. (Which Canada remains a part of, whether Trudeau likes it or not.)

The growing tensions with a rising China are a big deal. It is only going to become a bigger deal. The Liberals need to get with the program. We hope to see more on this across the Canadian media — and hopefully it’s a bit more useful and productive than what the Sun ran with this week. The Liberals look terrible on this file already for entirely legitimate, serious reasons. We don’t need to pop our aging joints as we stretch and contort ourselves to make it seem so.

The Russian Orthodox Church was once an all-mighty institution throughout what was the Russian Empire. But now in a matter of years, it has been completely swept aside by the new Soviet government in the name of progress and reason. This is just one — particularly violent — example of what has been a common theme of this era: the conflict between religion and modernity.

It has already come a few times in the series and will continue to do so, but it’s not always a story of retreating faith like it is in this episode. As you will see in later episodes, organized religion often fights back against modernity and even sometimes tries to accommodate it. You’ll have to stay tuned to find out exactly why.

Why Everybody Disagrees on the Efficacy of the English Longbow – A Video Essay

Published 7 Feb 2021

Everybody quarrels over the efficacy of the English longbow. Many historians, reenactors and history enthusiasts alike hold the view that arrows piercing armor is a myth. Some base this view on testing as was done for example by Tod from Tod’s workshop. Together with his team, he provided an invaluable data point for this debate. Others, such as traditionalist historians are often open to the possibility of arrows piercing armor, even though they are aware of actual testing of the longbow. In general, the efficacy of a weapon is much more complicated than its mere armor penetration value. So, in this video we’d like to shed light on the whole debate and explain why it is so hard to find common ground on this issue. This is why everybody disagrees on the efficacy of the English longbow.

From an improbable 1930s “death ray” to the radar network that helped defeat the Blitz

Filed under: Britain, History, Military, Science, Technology, WW2 — Tags: , , , — Nicholas @ 03:00

In a story from a few years back, Tim Harford outlines how a British Air Ministry prize for developing a “death ray” to use against enemy aircraft eventually helped kick off the discovery of radar:

The Chain Home radar tower in Great Baddow Chelmsford.
Photo by Stuart166axe via Wikimedia Commons.

… sometimes inventions need other inventions to unlock their full potential.

For the aviation industry, that story starts with the invention of the death ray, or at least an attempt to design a death ray, back in 1935.

Officials in the British Air Ministry were worried about falling behind Nazi Germany in the technological arms race.

The death ray idea intrigued them: they had been offering a £1,000 prize for anyone who could zap a sheep at a hundred paces. So far, nobody had claimed it.

But should they fund more active research? Was a death ray even possible?

Unofficially, they sounded out Robert Watson Watt, of the Radio Research Station.

And he posed an abstract maths question to his colleague Skip Wilkins.

“Suppose, just suppose,” said Watson Watt to Wilkins, “that you had eight pints of water, 1km [3,000ft] above the ground.

“And suppose that water was at 98F [37C], and you wanted to heat it to 105F.

“How much radio frequency power would you require, from a distance of 5km?”

Skip Wilkins was no fool.

He knew that eight pints was the amount of blood in an adult human, 98F was normal body temperature and 105F was warm enough to kill you, or at least make you pass out, which — if you’re behind the controls of an aeroplane — amounts to much the same thing.

So Wilkins and Watson Watt understood each other, and they quickly agreed the death ray was hopeless: it would take too much power.

But they also saw an opportunity.

Clearly, the ministry had some cash to spend on research. Perhaps Watson Watt and Wilkins could propose some alternative way for them to spend it?

Wilkins pondered. It might be possible, he suggested, to transmit radio waves and detect — from the echoes — the location of oncoming aircraft long before they could be seen.

Watson Watt dashed off a memo to the Air Ministry’s newly formed Committee for the Scientific Survey of Air Defence. Would they be interested in pursuing such an idea? They would indeed.

What Skip Wilkins was describing became known as radar.
