A truck wedged under a bridge, its roof peeled back like a sardine can, is such a familiar sight that the Australian city of Melbourne turned one bridge into a folk legend. The Montague Street rail bridge has claimed so many trucks that someone built a website tracking how many days since it was last hit. Bridge strikes are not exotic. They are one of the most repetitive failures in road transport.

Which brings us to a stretch of Central New York in the spring of 2026, and a load that never should have been on the road at the height it was.

What happened over 60 miles of the Thruway

On March 18, 2026, a tractor-trailer hauling an over-height excavator on a flatbed struck multiple overpasses as it traveled west on the Thruway.

The scope is what makes it notable: more than a dozen overpasses hit across roughly 60 miles between Exits 30 and 36.

The driver, 38-year-old Oleksander Tarakanovskyi of North Carolina, was apparently unaware that his load had struck the bridges. After the Thruway Authority alerted State Police, troopers found the truck and stopped it at the Mattydale tandem lot in the town of Salina.

Tarakanovskyi was charged with reckless endangerment in the second degree and issued more than 20 traffic tickets, including violations of federal commercial motor vehicle safety regulations. He was released with an appearance ticket returnable to Salina Town Court on April 8.

The reaction from officials was blunt. Frank G. Hoare, executive director of the Thruway Authority, said, “How a tractor trailer driver could be unaware that his load hit more than a dozen bridges is beyond comprehension.” State Police Major Brian T. Ferrone added, “Reckless, egregious behavior will not be tolerated.”

Why bridge strikes keep happening

The public record does not explain how Tarakanovskyi failed to notice the impacts. But the larger bridge-strike problem often starts before a truck reaches the bridge: with the vehicle’s height and route.

A Network Rail survey in the UK, part of its “Wise Up, Size Up” campaign, found that 43 per cent of lorry drivers admitted they did not measure their vehicle before setting off, while 52 per cent said they did not take low bridges into account. That’s UK data, not a direct explanation for this New York incident, but it shows why height checks and route planning are central to bridge-strike prevention.

Where the safeguards are supposed to catch it

In the US, there is no single federal vehicle-height limit; state limits for standard commercial vehicles commonly run from 13 feet 6 inches to 14 feet. On the New York State Thruway, loads 13 feet 7 inches or higher require a special hauling permit.

Permits, approved routes, escorts and height poles are all meant to move the moment of discovery to before the trip, rather than after a bridge is hit.

Take the King Street Bridge over the Hutchinson River Parkway in Westchester County. It was 

The wider problem has been documented for years. A 2013 City College of New York study found that bridges in the state were experiencing roughly 200 strikes annually at the time, with many concentrated on a much smaller group of repeatedly hit bridges.

A solvable problem that stays unsolved

At a 2018 meeting about bridge strikes on the Hutchinson River Parkway, Westchester County Executive George Latimer captured the exasperation. “This is a solvable problem,” he said, adding, “If government can’t solve a problem like this, then government can’t do anything.”

The engineering measures are familiar: know the vehicle’s height, plan a legal route, use permits and escorts where required, and install detection systems where repeated strikes justify them. The hard part is making those checks work consistently across a large road network.

The 2026 Thruway incident stands out because one over-height load allegedly produced a 60-mile trail of damage before police stopped it. But the underlying failure was not new. Bridge strikes are repetitive precisely because the safeguards depend on measurements, route choices and warnings being acted on before the truck reaches the bridge.

A London doctor traced hundreds of cholera deaths in 1854 to one neighborhood water pump and persuaded the parish to remove its handle — months later he mapped the outbreak, years before contaminated water was widely accepted as a cause of cholera

16 September 2026 at 12:45

A mother rinsed her baby’s dirty nappy in a bucket and tipped the water into the cesspool outside her front door. Within ten days, more than 500 of her neighbours were dead. If Henry Whitehead’s later reconstruction was right, hers was where it started.

The baby was five months old and lived at 40 Broad Street, Soho, in a district of tenements chopped into cheap rented rooms. Her death, on 2 September 1854, went into the records as diarrhoea rather than cholera, so she never appeared in the tally that made the street famous, as Gavi’s account of the outbreak notes.

Ten minutes’ walk away in Sackville Street lived a physician named John Snow, who had spent five years arguing that cholera travelled in water and getting nowhere. His 1849 essay on the subject was largely ignored by the medical profession. Respectable opinion held that epidemic disease rose off rotting matter as a poisonous vapour, a theory called miasma. Under miasma, the smell was the disease.

The map was made of black bars

Snow got the addresses of the dead from the General Register Office and walked them. He knocked on doors, asked survivors where they drew their water and worked out that the deaths clustered overwhelmingly around one public pump on Broad Street.

Months later he turned that investigation into the map that became famous, marking each known death as a short black bar at the address where it happened. By December he had tracked down 616 deaths, though only 574 could be placed on the map itself, the rest belonging to people who had died away from the district with no address on record. He published it in the second edition of On the Mode of Communication of Cholera in 1855.

He had no germ, no culture and no microscope image worth anything, only addresses.

The strongest evidence came from people who survived

Seventy men worked at the brewery on Broad Street and not one of them died. They drank a daily beer allowance, used a private well and never touched the public pump, per the Science History Institute’s account of the investigation. A workhouse squarely inside the death zone held over 500 people, lost only a handful and had its own supply.

Then there was the widow. A woman in Hampstead, miles to the north, died on 2 September, her visiting niece the day after. Neither had set foot in Soho for years. Snow went up to interview her son and learned she had once lived on Broad Street, liked the taste of the water and kept a servant carting bottles of it north. Her last delivery arrived on 31 August, the night the outbreak began.

Geography was the wrong variable and plumbing was the right one.

The parish agreed and the government did not

On the evening of 7 September, Snow put his case to the Board of Guardians of St James parish. They were sceptical of the theory and impressed by the arithmetic, and the handle was unscrewed the following morning.

Deaths were already falling by then, as Snow himself acknowledged. Thousands had fled the neighbourhood, and the contamination that triggered the outbreak had probably washed through days before.

The national verdict was blunter. England’s General Board of Health reviewed Snow’s theory through its Committee for Scientific Inquiries and rejected it outright: “After careful inquiry we see no reason to adopt this belief.” That committee, as Nigel Paneth and colleagues documented in the American Journal of Public Health, spent roughly a third of its 352-page scientific appendix on barometric pressure, wind direction, cloud cover and ozone levels. One of its own inspectors had handed Snow the Hampstead evidence.

The curate who found the first case

Henry Whitehead, assistant curate of St Luke’s on Berwick Street, had spent the outbreak climbing those stairs with food and last rites. He thought Snow was wrong, and joined the parish inquiry committee partly to clear the pump’s name. Snow gave him a copy of the monograph and he read it and stayed unconvinced, so he went out to disprove it. In April 1855, seven months after the last death, he traced the chain back to the baby at number 40, a case Snow had never counted, as S.P.W. Chave set out in Medical History.

The parish surveyor dug up the well and found the cesspool brickwork rotted through, inches from the well lining.

Whitehead also worked out what taking the handle off achieved. The baby’s father came down with cholera on 8 September, the morning the parish disabled the pump, and his waste would have gone the same way his daughter’s had.

Snow died in 1858, aged 45, with the profession still against him. In Florence that same autumn of 1854, an anatomist named Filippo Pacini had put cholera discharges under a microscope, seen comma-shaped organisms swarming in them and published. Italian medicine believed in bad air too, and Pacini’s finding went unnoticed by Snow, by Robert Koch and by almost everybody else until long after his death. Bacteriologists made it official in 1965, naming the organism Vibrio cholerae Pacini 1854.

Two men landed on the answer in the same year, in two cities, and the medical establishment believed neither of them. The handle came off anyway.

The U.S. government accidentally sold an Apollo 11 bag still carrying traces of moon dust for just $995 in 2015 — the Illinois woman who bought it survived a legal fight with NASA, then sold the same bag at Sotheby’s two years later for $1.8 million

16 September 2026 at 12:30

For $995 you could buy a decent second-hand lawnmower, a mid-range mattress, or, if a government spreadsheet has a bad day, a piece of Apollo 11 with moon dust still caught in its seams.

That last one happened. In February 2015, an online auction held on behalf of the US Marshals Service listed a white zippered pouch stamped “Lunar Sample Return”. Nancy Lee Carlson of Inverness, Illinois, bid $995 and won. She knew it had flown on something. What she did not know was that it had ridden along on the first crewed landing on the Moon.

How a moon bag ended up in a garage in Kansas

Blame starts with Max Ary, who ran the Kansas Cosmosphere and Space Center in Hutchinson from 1976 to 2002 and was convicted in November 2005 on twelve federal counts, including theft of government property, wire fraud and money laundering. Investigators searching his garage two years earlier had found a box, and the bag was inside it. As documented by The Hutchinson News, Ary was ordered to pay more than $132,000 in restitution for the space artefacts he had taken, a mix of property belonging to NASA and the museum itself. He always maintained he had simply muddled his own collection with theirs.

His forfeited property went to auction to cover the bill. That is where the mix-up happened. Per the Associated Press, government officials later said two lunar bags had been merged into a single entry when their inventory numbers were combined on spreadsheets. One was from Apollo 17. The other had been to the Sea of Tranquility, and nobody caught the difference before the gavel came down.

What the fabric was hiding

Carlson did the sensible thing and posted the pouch to NASA’s Johnson Space Center for authentication.

Terrible idea, as it turned out. Curators tested the cloth, found lunar material embedded in the fibres, and established that the pouch had served as the outer decontamination bag around the first rocks Neil Armstrong scooped up during the Apollo 11 moonwalk. Then NASA kept it, arguing the bag was government property that should be on public display, not sitting in someone’s living room, and asking the Justice Department to reverse the forfeiture.

Carlson sued. Twice, in two states.

The ruling nobody at NASA wanted

In December 2016, Judge J. Thomas Marten of the US District Court for Kansas ruled that Carlson was “a good faith purchaser, in a sale conducted according to law,” as reported by Robert Pearlman at collectSPACE. Marten went out of his way to say NASA had done nothing wrong here, and that the bag only mattered at all because of what NASA’s own people had pulled off in 1969. He also said he had no power to unwind a sale that had already gone through. Space.com later reported that NASA handed the bag back in February 2017.

Sold at Sotheby’s, well short of the estimate

Sotheby’s offered the pouch on 20 July 2017, 48 years to the day after Armstrong used it. NPR put the hammer price at $1.5 million, or $1,812,500 once Sotheby’s premium was added, which sounds enormous until you notice the house had estimated $2 million to $4 million. The buyer stayed anonymous.

Plenty of people thought the sale should never have happened at all. Michelle Hanlon of For All Moonkind, a group campaigning to protect the Apollo landing sites, said in a statement carried by Smithsonian magazine that the bag belonged in a museum where the world could share in the achievement it represents. Carlson told CBS News she decided to sell because she no longer felt it was safe in her home.

The dust went on to have its own career

NASA’s testing had lifted particles off the bag onto carbon tape mounted on aluminium stubs, and the agency held on to them after returning the pouch. collectSPACE reported that Carlson sued again in January 2019, claiming the testing had damaged the bag, dragged down its market value and caused her real distress, and demanding the return of the lunar material itself. That dispute settled out of court, and the samples went to her.

Which is how, in April 2022, five aluminium stubs, each topped with a 10-millimetre disc of carbon tape, came up in a New York saleroom. Bonhams sold them for $504,375, well under a pre-sale estimate of $800,000 to $1.2 million. Bidding opened at $220,000, seven bids came in, and the hammer fell at $400,000. Independent testing found four of the five stubs carried particles matching Armstrong’s first sample.

NASA still holds almost all of the 382 kilograms of rock, dust and core material brought home by the six Apollo landings. Its position on the rest hasn’t shifted in half a century: this material belongs to the public, not to private collectors. That stance holds up fine, right until two rows get merged on a spreadsheet.

Somewhere out there is a collector nobody can name, holding a cloth bag worth more than most houses, backed by a government receipt for $995 confirming the sale was done by the book.

After a munitions ship exploded in Halifax in 1917, Boston mobilized doctors, nurses and medical supplies and sent them north by train through a blizzard — more than a century later, Nova Scotia still sends Boston a giant Christmas tree each year in thanks

16 September 2026 at 12:15

A sailor burst into a small wooden railway station in the north end of Halifax on the morning of 6 December 1917 and told everyone inside to run.

Vince Coleman, the dispatcher on duty, walked back to his telegraph key instead. As the Maritime Museum of the Atlantic recounts, he was thinking about the overnight passenger train from Saint John, roughly 300 people aboard, due in at 8:55am on a line that ran straight past a burning munitions ship. He tapped out a warning to hold the train, then signed off: “Guess this will be my last message. Good-bye, boys.”

Minutes later the French cargo ship Mont-Blanc, packed with explosives bound for the war in Europe, detonated in Halifax Harbour.

A city with 2,000 dead and no spare hospital beds

Almost every building within half a mile of the water came down, and records held by the Massachusetts State Library put the immediate toll at 1,800 killed, 3,000 seriously wounded and another 10,000 needing medical attention. Later counts settle at close to 2,000 dead.

Halifax was in no position to absorb that. It was a wartime port, and as the medical journal Proto has documented, local hospitals were already carrying soldiers sent home to recover. Doctors worked through the first night and kept going.

Then it started to snow.

Boston did not wait to be invited

News crossed the wires and landed on the desk of Massachusetts governor Samuel McCall around 11am. What he had was fragmentary at best, a few lines about some sort of catastrophe up the coast. Writing in its account of that day, the Massachusetts Historical Society notes that McCall wired back a promise that his state would go the limit, and called an emergency meeting of the Committee of Public Safety.

By 10pm, twelve hours after the blast, a relief train loaded with doctors, nurses and supplies pulled out of Boston. Nobody in Halifax had yet told them what was needed.

A blizzard caught the train en route, hardly a surprise for Maine and New Brunswick in December. It did not turn back. Staff wired ahead for extra supplies while they were still stuck in the drifts, and the Halifax Municipal Archives documents the first American medical train arriving on 8 December, having pushed through snow for most of the trip.

The help kept arriving for years

That first train turned out to be the opening instalment. Author John U. Bacon, speaking to WBUR about his book on the disaster, counted two trains, two ships, 100 doctors, 300 nurses and about a million dollars in supplies, enough to stand up several temporary hospitals.

The medical unit went home on 14 December and formed the Massachusetts-Halifax Relief Committee on the journey back. The same archive shows it raised half a million dollars, refurnished more than 1,800 homes and set aside $25,000 for the care and education of people blinded by flying glass. Halifax named a block of temporary housing the Governor McCall Apartments, on a newly laid-out Massachusetts Avenue.

One tree in 1918, then a gap of fifty-odd years

Nova Scotia sent Boston a Christmas tree the following December as a thank you, and the tradition quietly lapsed.

It came back in 1971, and not purely out of sentiment. As reported by The Signal, the Lunenburg County Christmas Tree Producers Association revived the gift with one eye on the export market for Nova Scotian spruce. The provincial government took the job over a few years later and has handled it ever since, which is how a one-off act of gratitude became a line item.

What it takes to qualify as the tree

Anyone can nominate one. Criteria published by the Government of Nova Scotia ask for a white spruce, red spruce or balsam fir standing 12 to 15 metres, healthy, good colour, medium to heavy density, uniform and symmetrical, and easy to get a truck near. Officials narrow the field before checking their shortlist with Boston.

Boston’s 2025 tree was a 45-foot white spruce nominated by Ronald and Claire Feener of Lunenburg County. It reached the Common by flatbed truck under police escort, the City of Boston confirmed. Mayor Michelle Wu flew up for the cutting and, as CBC News reported, took a turn with the chainsaw herself on a 42-year-old spruce while a certified tree-felling instructor supervised.

That was a year of tariff threats and cross-border sniping, and the tree went south anyway.

Most international goodwill exists as paperwork nobody reads. This one gets scouted for months, felled in front of a crowd, driven hundreds of kilometres and switched on in a public park every December, all because a train once left Boston into a blizzard for a city that had barely had time to explain what was wrong.

American employers told young women painting luminous watch dials that radium was harmless and instructed them to shape the radioactive brushes with their lips — the lawsuits that followed helped establish that employers could be held financially responsible for harm caused by their work

16 September 2026 at 11:45

The women walked home at night and glowed.

Radium dust settled in their hair and on their coats, so a dial painter leaving the plant in Orange, New Jersey, trailed a faint shimmer down the footpath. Plenty of them thought this was marvellous. They painted their fingernails with it and dabbed it on their teeth before a dance. Nobody in management suggested they stop.

The paint was branded Undark, a mix of radium and zinc sulfide developed by Dr Sabin von Sochocky. In its account of the digitised company files, the National Archives describes how the Radium Luminous Material Corporation opened its Orange factory in 1917, selling the glow to watchmakers and instrument firms. Radium dials were prized in the trenches of the First World War and fashionable everywhere else.

How the paint got into their bones

Brushes were the whole problem.

Camel-hair bristles lose their point after a few strokes, and the numerals on a wristwatch face are minute. So the painters were taught to roll the brush between their lips before each dip. Lip, dip, paint, several hundred times a shift. The Science Museum Group notes that the New Jersey women worked on paper dials with a water-based paint, applied with fine camelhair brushes rather than the metal stylus used elsewhere in the industry. A trace of radium went down the throat with every dial.

Radium behaves chemically like calcium, so the body lodges it in bone and leaves it there, decaying quietly, for a life that just got much shorter.

The doctor who worked it out

Dentists noticed first. From about 1922 they were pulling aching teeth from young women in Orange, finding that pieces of jawbone came away too. A dentist, Theodor Blum, described the condition in 1924 and named it radium jaw.

Harrison Martland, the Newark pathologist who became Essex County’s first medical examiner, took it further. Writing in the Journal of the American Medical Association in 1925, he measured radioactivity in the tissue of dead dial painters and in the exhaled breath of living ones. A retrospective in Brain credits that work with pioneering the measurement of radioactivity inside contaminated human tissue.

U.S. Radium hired its own experts to challenge his findings. Reasonable enough in 1925, when one man’s diagnosis was still just one man’s diagnosis, though the company kept denying any link to radium for another decade.

Five women, one settlement, no admission

Grace Fryer needed two years to find a lawyer who would take her case. Katherine Schaub, Edna Hussman, Quinta McDonald and Albina Larice joined her, and by the first hearing in January 1928 none of the five could lift an arm to swear the oath.

They settled that June for $10,000 each, an annuity of $600 for life and their medical bills covered. The company admitted nothing, and most dial painters received no compensation at all, the National Archives notes. In 1936, a federal court in New Jersey ruled that U.S. Radium had not fraudulently hidden the danger, a decision that pushed surviving claims outside a two-year limitation period and effectively ended them.

What happened in Ottawa

Meanwhile, in Ottawa, Illinois, the Radium Dial Company assured its painters that the Orange trouble had nothing to do with them, since the radium over there was impure. The firm had been medically screening its own workers since 1925 and keeping the results to itself. As History.com documents, Illinois workers lost in court through the mid-1930s, after which the state passed the Illinois Occupational Diseases Act, effective 1936, requiring employers to carry cover for industrial poisoning.

Catherine Donohue led fifteen women in a fresh suit in 1937. By a hearing the following February she weighed around 32 kilograms and had to be carried into the room, and, as Northern Public Radio reported, she arrived with a box of what she said were pieces of her own jawbone. Local papers took to calling the group the society of the living dead, NPR Illinois reports, and their lawyer, Leonard Grossman, took the case for free because his clients had nothing to pay him. Later hearings moved to Donohue’s home, where she testified from a couch because she could no longer travel.

The Illinois Industrial Commission ruled for Donohue in April 1938 and confirmed the award that July. She died on 27 July, three weeks later. Radium Dial fought on regardless. The Illinois Supreme Court threw out the company’s petition to overturn the award in June 1939, and the U.S. Supreme Court declined a further appeal that October, more than a year after Donohue’s death.

That refusal to intervene left the award standing, and with it the principle that an employer could be held liable for a disease that surfaced years, sometimes a decade or more, after the job ended. Grossman’s son, three decades a Department of Labor lawyer, traces a line from those hearings to the federal OSHA Act, which he dates to 1971.

The measurements they left behind

Many surviving painters later volunteered their bodies to researchers at Argonne National Laboratory, whose review of the radium cases sets out how those measurements shaped radiation protection limits for the nuclear age.

Radium-226 has a half-life of roughly 1,600 years, so the women are still faintly radioactive in their graves and will be long after everyone reading this is gone. A surprising amount of modern workplace law rests on that fact. None of them were trying to found a legal doctrine. They wanted someone to pay the dentist.

In 2025, researchers ground retired wind turbine blades into powder, stirred it into a gel and set it into an insulation composite. The composite combined low density with much greater compressibility than many of the insulating aerogels and composites it was compared with, squashing to a fifth of its thickness without breaking apart.

16 September 2026 at 11:00
Wind turbines under a clear blue sky symbolize clean energy and sustainability.

A wind turbine blade is basically glass fibre set in hardened resin. The fibres give it strength, the resin holds them in place, and the two are bonded so tightly that a blade can survive wind, rain and stress.

That same toughness is the problem once the blade comes down. Thermoset epoxy does not melt back into a workable liquid, and its stable chemical bonds are difficult to break. So retired blades are typically cut into sections and sent to landfill.

That is the waste a group of researchers decided to work with. In a 2026 study published in ACS Applied Engineering Materials, a team at Xi’an Shiyou University, with collaborators at the Beijing Institute of Technology and Monash University, ground old blade material into powder and turned it into a lightweight, sponge-like insulation.

Here is what came out of the lab, and how it stacks up against the size of the problem.

It squashes to a fifth of its thickness and springs back

The most surprising thing about the material is how far you can crush it without wrecking it. The team reports it took a squeeze of over 80 percent and recovered, meaning you can press it down to roughly a fifth of its height and it bounces back. That matters because conventional silica aerogels are famously fragile. They insulate well but can be brittle. A material that can take a squeeze and spring back is far easier to handle and install.

The trick is in the structure. Instead of a solid block, the composite is a network full of tiny connected pores, with the blade powder stiffening a soft, springy scaffold. 

It combined low density with unusually high compressibility

Weight is where the main result sits. The material reached a density of 0.184 grams per cubic centimetre while sustaining more than 80 percent compressive strain. The authors say the composite showed “a superior combination of low bulk density (0.184 g cm–3) and high compressive strain (>80%), outperforming a wide range of reported silica-based or organic aerogels and composites.”

A caution is warranted: that line is the researchers describing their own work, not an outside verdict. “Outperforming” is their framing, and the comparison is against numbers from other published papers rather than a head-to-head test by a neutral lab. The figures themselves are measurable; whether the material performs as well in practice is the kind of thing other labs and larger-scale testing would need to settle.

It holds heat in about as well as ordinary insulation

Being light and squishy would not count for much if heat poured straight through it. It doesn’t. The composite measured a thermal conductivity of 0.068 watts per metre-kelvin, and lower is better here because it means less heat gets across. For comparison, ordinary glass wool building insulation sits around 0.04. So the blade composite is not a record-setting insulator, but it is in a sensible range for the job while remaining highly compressible.

It self-extinguishes instead of feeding a flame

Insulation lives inside walls and roofs, so how it behaves near fire matters. The team reports enhanced flame self-extinguishing capability, meaning it tended to stop burning once the flame source was removed rather than carrying the fire along. Again, this is one lab result on lab samples, though, and real fire-safety ratings require standardised testing. Read it as promising, not certified.

It turns a landfill problem into the raw material

The reason any of this is interesting is the sheer number of blades headed for the ground. Worldwide, the mass of blades expected to be discarded by 2050 may reach about 43 million tonnes. Right now, around 12,000 blades are retired across Europe and the US each year, and they are typically cut up and sent to landfill. A process that takes that same material and makes something useful flips the equation.

As the authors put it, reusing the blade waste “not only helps to reduce environmental burdens and resource waste but also opens up avenues for generating high-performing, useful materials.”

Where this actually sits

This is one study and one set of lab measurements. The chemistry is clever and the numbers look good, but the gap between a lab composite and a pallet of insulation shipped to a building site is wide. The paper doesn’t answer the questions that fill that gap: cost, batch-to-batch consistency, how the material holds up over years inside a wall, and whether grinding and processing old blades at scale actually makes economic sense.

That last question is the real hinge. Something has to make the recycled route cheaper or required before a lab result becomes a real supply chain.

None of that takes away from what the team built. This is a good answer to a narrow question, which is whether hard-to-recycle blade waste can be turned into a useful, light, tough insulating material at all. The evidence here says yes. The bigger question, whether it can be done by the tonne cheaply enough to matter, is still open.
