Comment on Why Scotland succeeded in ~humanities.history
skybrian LinkFrom the article: [...] [...] [...] [...]From the article:
But by the 1740s, the first signs could be seen of a spectacular change. Glasgow, whose merchants had long ago carved out a respectable share of the tobacco imported to Britain from Virginia, suddenly and rapidly came to dominate the trade. From controlling just 10% of tobacco imports in 1738, just twenty years later Glasgow had surpassed even gargantuan London. Another ten years on, by 1769, Glasgow accounted for more than every other British port combined, while all the time the total amounts of tobacco imported grew and grew.7 Contemporaries estimated that the shipping tonnage on Glasgow’s river, the Clyde, had increased more than tenfold.8 Edinburgh meanwhile saw its shops fill with luxuries, and its university become a centre of excellence in medicine and chemistry, drawing students from across northwestern Europe, while the city itself expanded, elegantly, with the building of the New Town.
[...]
For many of those who lived through it, such as the agricultural labourers who faced eviction in the name of improvement, or the slaves on American plantations who grew the tobacco with Scots linen on their backs, Scotland’s transformations were painful, or even strictly for the worse. Yet all the transformations, for better and worse, all had a common root – a factor that made possible the sheer pace of Scotland’s simultaneous agricultural, industrial, and urban revolutions, squeezing into the space of just a few decades what had taken England at least a century and a half, and then allowing it to grow even faster still. Each of the changes required extraordinary levels of investment, which was only made possible because despite the Union, Scotland retained a difference in law and institutions that made it uniquely supportive of the raising and deploying of capital.
[...]
Whereas in England a company needed a royal charter or a special act of parliament in order to be a distinct legal entity, with partnerships according to English common law being no more than the sum of their parts, Scots law instead enabled unchartered firms to be distinct from their owners in lots of important ways, able to outlast the partners who died or went bankrupt, with shares able to be easily traded or transferred, and enabling profits to be preserved for reinvestment in the firm rather than being dissipated in dividends. As a result, even the unchartered banks in Scotland could have dozens or even hundreds of partners drawn from across the upper and middle classes, whereas the average in England had just three.12
Scottish banks started up with more capital, grew faster, drew on a much deeper pool of investors, and were significantly more stable and resilient to shocks. And in all having to compete with one another they offered financial services that were unheard of south of the border – they had local branches, paid interest on deposits, and readily offered short-term loans on personal security rather than just on land. The second of the chartered banks, the Royal Bank of Scotland, in 1728 seems to have been the first bank in the world to have ever offered overdrafts, called the “cash credit” system.13 In the 1810s Scotland developed the savings bank, which paid interest on even the tiny deposits of artisans and labourers.14
And the Scottish banks issued plentiful banknotes in small denominations that were able to circulate in the economy as currency, finally satiating Scotland’s decades-long want of coin.15 Indeed, Scots law made it much quicker and easier than in England to enforce all sorts of debts.16 With creditors made confident, they were much more willing to lend, making more capital available to grease commerce’s wheels.
[...]
When the Virginian tobacco planters all defaulted during the American Revolution, and the warehouses were all seized, Glasgow’s merchants were so well-capitalised that they could largely take the loss, and simply switch to dominating the trade in Caribbean sugar and cotton in the same ways instead. Indeed, by out-lending their competitors in order to capture the trade, and so allowing planters to clear land and buy slaves before they’d even grown their crop, Glasgow’s merchants provided the capital that enabled the plantations of first Virginia and then the Caribbean to so rapidly expand.17 Although it’s often said that slavery and colonialism funded Glasgow’s growth, it was largely the other way around: the Atlantic economy’s heyday was built on the savings of Scots.
[...]
Much the same can be said of how Scotland assembled the capital for its mills, mines, ironworks, farms, and a host of other trades,20 as well as how it built its infrastructure, from harbours, bridges, canals, and later railways, to city water supplies, street paving, hospitals, and civic buildings. When new industries were invented, it was Scottish capital that ensured the country pursued it on a large scale. The St Rollox chemical works in Glasgow, founded by a former weaver and bleacher, Charles Tennant, was in the 1830s and 40s reputedly the largest heavy chemical plant in the world.21
But even more fundamentally, Scotland’s unique financial system in the late eighteenth and early nineteenth centuries made it possible for ambitious individuals to borrow even when they owned no land, based only on the personal security of themselves and their guarantors, and so to raise the capital that merely their reputation, skill and acumen might command. Scotland was thus uniquely supportive of the ambitious “lad o’ pairts”, or of the artisan with a new idea for an invention, who wanted only capital to make it real. It was the obvious place, thanks to Samuel Smiles in the 1850s, to have spawned the entire literary genre of self-help.

Comment on Diamonds or dust, coal under pressure in ~enviro
skybrian LinkFrom the article: [...] [...] [...] [...] [...] [...] [...]From the article:
From emergency orders to the war in Iran, the Trump Administration has kept coal in the headlines, but even before the 202(c) orders started rolling in, coal generation’s decline in America had slowed.
Volatile natural gas prices, load growth, rising capacity payments, slowdowns across supply chain and planning processes, and a rollback of environmental regulations have all converged to provide purchase for America’s remaining coal fleet. Not only to extend survival, but even increase generation across the country.
[...]
Many were quick to blame coal’s decline on the push to bring wind and solar online, but the main driver was another fossil fuel, natural gas. Following the fracked shale revolution in 2008, and the year Tony Stark became Iron Man, natural gas production boomed and prices, while not immune to volatility, cratered. This fueled the buildout of combined cycle plants, which were substantially more efficient and flexible than traditional coal-fired steam turbines. Falling energy and capacity prices made coal increasingly uneconomic, which, paired with plant aging, limited flexibility, rising maintenance costs, and stricter environmental standards made retirement the typical choice.
[...]
The Trump administration’s slogan has been Energy Dominance, but this ethos only extends to certain technologies. If you’re big, loud, and burn you’re getting support, missing any one of the trifecta and you’ll have a much harder road from the federal government. Coal represents all three attributes to a T. Energy Dominance hasn’t just been executive order rhetoric, but manifested in significant and ongoing extension orders for coal plants that had previously planned retirement.
[...]
Section 202(c) orders were not just issued for plants that were fully expected to retire. Two coal units in Colorado, Craig 1 and Comanche 2, were kept online in 2025, though under different circumstances. Comanche 2 was extended for reliability reasons as the plant's other unit, Comanche 3, is currently undergoing extensive repair. These repairs, which are expected to take over a year, left PSCO with limited dispatchable power during the peak seasons.
The extended outage at Comanche 3 points to a wider issue at many plants, one that is also impacting Craig 1. As plants age, maintenance, as well as new costs, like scrubbers to meet enhanced emissions standards, cut into operating expenditures. While rising power and capacity prices have made existing assets more profitable in recent years, these costs come after tight margins at many units over the 2010s and early 2020s. This is the case at Craig 1 as well, which has seen generation drop over the years and suffers from deferred maintenance. Plant operators argued that they had built up sufficient wind and solar resources that made the plant unnecessary, filing a petition against the DoE making that exact argument. Craig also has units 2 & 3 that are currently in better condition and continue to run and support the stack.
[...]
While gas is displacing coal, it doesn’t travel along the same paths. Coal relies on rail and barge, while natural gas is transported almost exclusively via pipeline with the US. Many natural gas producers even own pipelines, and pipelines only transport natural gas. Conversely, transit via 3rd parties comes with cross-commodity competition and the potential for disruptions such as rail strikes. Five states dominate US coal production: Wyoming, West Virginia, Pennsylvania, Illinois, and Kentucky. Massive surface mines in the Western US account for the majority of coal extraction in the country, and rail is the main transportation method for coal from these locations to power plants.
[...]
The differences in logistics between the thermal fuels create an environment where they can act complementary to one another. Providing different levels of support should one resource become constrained physically and subsequently economically. Coal can be stored more readily, while natural gas can be transported more quickly in its just-in-time system with very expensive and limited storage. In fact, this mirrors an older version of the US power system, a vast coal baseload with natural gas balancing. That environment, pre-shale, pre-renewables, is the one in which power markets were conceived of and originally designed. Market development in the context of a more predictable system is having knock-on effects today, with core elements like FTRs struggling to keep up.
[...]
In the short term, coal has tailwinds in the US and abroad. In fact, it’s possible that the attacks on Iran were the single most impactful pro-coal policy decision the Trump administration has made to date. Reminding the world of the difficulties associated with storing and transporting liquids and gas through highly concentrated corridors of supply with a history of instability can be a powerful motivator to cling to coal
On the flip side, the US has retired nearly 150 GW of coal capacity, and the last plant to be built was six years ago, in Railbelt Alaska, near (for Alaska) a mine, and replacing an older plant in the same spot. Meanwhile, that same reach for stability could trigger demand destruction for fossil fuels entirely. After all, everywhere has access to sun and wind, allowing some freedom from the whims of ancient life and geology.
[...]
For the immediate future, all signs point to continued extensions of existing plants. While the twin forces of Trump 2.0 and load growth seem unlikely to abate in the immediate future, it’s important to keep in mind that retiring any part of the energy system is fundamentally difficult. Many observers have noted that historically we’ve layered new systems on top of old, rarely reaching complete excision. Where it has come, regions have taken different paths. Just in North America we have CAISO’s monomaniacal focus on new technologies while maintaining strong regional interconnections, Ontario’s pivot to focus on the baseload they already had in excess, or a market like NYISO where coal had become uneconomic relative to gas and the state had big future plans.

Comment on Study finds sperm whales help each other give birth in ~science
skybrian LinkFrom the article: [...] [...]From the article:
Project CETI (Cetacean Translation Initiative) has released two landmark scientific papers detailing what researchers describe as the most comprehensive record of a sperm whale birth ever captured – and the first quantitative evidence of cooperative birth assistance among non-primates.
Published in Science and Scientific Reports, the studies draw on more than six hours of underwater acoustic recordings and aerial drone footage collected on 8 July 2023 in waters off Dominica.
[...]
Taken together, the studies suggest that cooperative caregiving during birth may be an ancient evolutionary trait. Phylogenetic analysis indicates that behaviours such as the collective lifting of newborns could predate the most recent common ancestor of toothed whales by more than 36 million years.
[...]
The research builds on decades of fieldwork led by Shane Gero, whose team has tracked the focal whale family since 2005. The mother – known as Rounder from Unit A – was observed giving birth alongside her own mother, Lady Oracle, and her daughter, Accra, capturing three generations participating in the event.
“This is the most detailed window we’ve ever had into one of the most important moments in a whale’s life,” said Shane Gero, Biology Lead for Project CETI, Scientist in Residence at Carleton University, and National Geographic Explorer.
“Because this family unit has been studied for decades, we could see what the grandmother was doing, how the new big sister acted, and how each helped mom and newborn, placing this rare birth within a deep social and behavioural context.”

Comment on An unstoppable mushroom is tearing through North American forests. Fungi enthusiasts are doing damage control. in ~enviro
skybrian LinkFrom the article: [...] [...] [...]From the article:
The golden oyster mushroom (Pleurotus citrinopileatus) is a close cousin of the grey oyster I dissected above. Instead of grey, it has a neon yellow cap, and it is prolific. The fungus itself mainly grows on dead or dying hardwood trees, breaking down the tough wood fibres. Golden oysters are "gilled mushrooms", and a single gilled mushroom can release up to billions of spores. Oyster mushrooms also happen to be one of the few carnivorous mushrooms – preying mercilessly on nematode worms.
It is invisible for most of the year, living as mycelium, fungal strands within the wood. But beginning in spring, it sends out its fruiting body – what we would recognise as the mushroom itself. Huge yellow clusters cascade out of logs and trees, each mushroom itself producing millions of microscopic airborne spores.
Native to Asia, the fungus was brought over to the US to be cultivated for food sometime around the early 2000s. Because it fruits so heavily, it proved to be popular with both professional and home growers. It has a high yield, meaning more profit for growers.
The mushroom is now found across the world. It's spreading in Switzerland, and has been found in Italy, Hungary, Serbia and Germany. There are reports of the golden oyster growing in the south of the UK too. The Royal Horticultural society has issued advice warning people against growing non-native species, especially the golden oyster, saying it was "highly invasive" and capable of causing "severe damage" to local fungal communities.
[...]
"We found that trees colonised by golden oyster have, on average, about half the fungal biodiversity as trees without the golden oyster. And so that was a huge indicator that they're likely out competing the native fungi that were there," says Veerabahu.
[...]
Other invasive species meanwhile are appearing in Europe. In October 2025, Poland's national forest management body sounded the alarm after a North American species, the slender golden bolete (Aureoboletus projectellus) was found in the Unesco-protected Białowieża Forest.
[...]
Climate change is also believed to be changing the distribution of fungi across the world. One species, the strikingly orange "ping pong bat fungus" (Favolaschia calocera), originally hails from tropical Madagascar. But it's been showing up in the wild in Dorset, southern England, where its effects on native fungi are unknown, something scientists believe is being helped by rising global temperatures.

Comment on How autonomous drone warfare is emerging in Ukraine in ~society
skybrian LinkFrom the article: [...] [...] [...] [...] [...]From the article:
A thorough analysis of the Middle East conflict will take some time to emerge. And so to understand the direction of this new way of war, look to Ukraine, where its next phase—autonomy—is already starting to come into view. Outnumbered by the Russians and facing increasingly sophisticated jamming and spoofing aimed at causing the drones to veer off course or fall out of the sky, Ukrainian technologists realized as early as 2023 that what could really win the war was autonomy. Autonomous operation means a drone isn’t being flown by a remote pilot, and therefore there’s no communications link to that pilot that can be severed or spoofed, rendering the drone useless.
[...]
Since then, The Fourth Law has dispatched “more than thousands” of autonomy modules to troops in eastern Ukraine (it declines to give a more specific figure), which can be retrofitted on existing drones to take over navigation during the final approach to the target. Azhnyuk says the autonomy modules, worth around US $50, increase the drone-strike success rate by up to four times that of purely operator-controlled drones.
And that is just the beginning. Azhnyuk is one of thousands of developers, including some who relocated from Western countries, who are applying their skills and other resources to advancing the drone technology that is the defining characteristic of the war in Ukraine. This eclectic group of startups and founders includes Eric Schmidt, the former Google CEO, whose company Swift Beat is churning out autonomous drones and modules for Ukrainian forces. The frenetic pace of tech development is helping a scrappy, innovative underdog hold at bay a much larger and better-equipped foe.
All of this development is careening toward AI-based systems that enable drones to navigate by recognizing features in the terrain, lock on to and chase targets without an operator’s guidance, and eventually exchange information with each other through mesh networks, forming self-organizing robotic kamikaze swarms. Such an attack swarm would be commanded by a single operator from a safe distance.
According to some reports, autonomous swarming technology is also being developed for sea drones. Ukraine has had some notable successes with sea drones, which have reportedly destroyed or damaged around a dozen Russian vessels.
[...]
While uncrewed aerial vehicles (UAVs) have received the most attention, the Ukrainian military is also deploying dozens of different kinds of drones on land and sea. Ukraine, struggling with the shortage of infantry personnel, began working on replacing a portion of human soldiers with wheeled ground robots in 2024. As of early 2026, thousands of ground robots are crawling across the gray zone along the front line in Eastern Ukraine. Most are used to deliver supplies to the front line or to help evacuate the wounded, but some “killer” ground robots fitted with turrets and remotely controlled machine guns have also been tested.
[...]
Today’s Shaheds fly faster and higher, and therefore are more difficult to detect and take down. Between January 2024 and August 2025, the number of Shaheds and Shahed-type attack drones launched by Russia into Ukraine per month increased more than tenfold, from 334 to more than 4,000. In 2025, Ukraine found AI-enabling Nvidia chipsets in wreckages of Shaheds, as well as thermal-vision modules capable of locking onto targets at night.
“Now, they are interconnected, which allows them to exchange information with each other,” Solntsev says. “They also have cameras that allow them to autonomously navigate to objects. Soon they will be able to tell each other to avoid a jammed region or an area where one of them got intercepted.”
[...]
MaXon’s solution consists of ground turrets scanning the sky with infrared sensors, with additional input from a network of radars that detects approaching Shahed drones at distances of, typically, 12 to 16 km. The turrets fire autonomous fixed-winged interceptor drones, fitted with explosive warheads, toward the approaching Shaheds at speeds of nearly 300 km/h. To boost the chances of successful interception, MaXon is also fielding an airborne anti-Shahed fortification system consisting of helium-filled aerostats hovering above the city that dispatch the interceptors from a higher altitude.
[...]
Despite the progress on both sides, analysts say that the kind of robotic warfare imagined by Azhnyuk won’t be a reality for years.
“The software for drone collaboration is there,” says Kate Bondar, a former policy advisor for the Ukrainian government and currently a research fellow at the U.S. Center for Strategic and International Studies. “Drones can fly in labs, but in real life, [the forces] are afraid to deploy them because the risk of a mistake is too high,” she adds.

Some investments take time. If a factory takes two years to build, and you don’t know what prices will be like in two years, should you build it? Maybe the crisis will be over and there will be a glut?
Consistent policy encourages long-term investments. When people do the calculations to figure out if an investment will pay for itself, that gives them solid numbers to work with. Short-term shocks, not so much.
