Q1541
WonderOcean

In the deep ocean, glowing is normal: about three-quarters of the animals living there make their own light.

A large survey of the water off California found that roughly 76% of the animals counted could produce light through bioluminescence. Down where sunlight never reaches, living light does the work instead — luring prey, confusing predators, and signalling to mates. What looks to us like an exotic trick is, in the largest living space on Earth, the ordinary way to be seen.

Sharks have swum the oceans for more than 400 million years — appearing before the first trees grew, and possibly before Saturn's current rings formed.

Sharks arose over 400 million years ago, while the earliest true trees came later, around 380 million years ago. Saturn's bright rings may be younger still — some evidence suggests the current ring system is only a few hundred million years old, so dinosaurs might have looked up at a ringless Saturn. Sharks have outlasted several mass extinctions, quietly persisting while the world rearranged itself around them.

Across decades of psychiatric records, researchers have found very few confirmed cases of schizophrenia in people born completely blind — one of the strangest open questions in medicine.

The clearest evidence comes from Western Australia, where Vera Morgan's team followed every one of 467,945 children born between 1980 and 2001. Around 1,870 went on to develop a psychotic illness — but not one of the 66 children born with cortical blindness did. The numbers are small, so nobody is calling it settled. One leading explanation is that schizophrenia involves the brain trusting its own predictions over the evidence of the senses; sight is our dominant prediction machine, so a brain that never built a visual model may be protected from that particular failure mode. It is a rare case where an absence — of cases, of vision — may be a clue.

When a song lands slightly off the beat, the brain's reward system can respond — we often enjoy music most when it bends the pattern without breaking it.

Your brain is a prediction engine: it guesses where the next beat falls, then checks. A perfectly regular rhythm is guessed correctly every time and quickly becomes dull. Syncopation — a note landing just off the expected beat — produces a small prediction error, and dopamine follows. Peter Vuust and colleagues found the effect follows an inverted U: too simple and there is nothing to be surprised by, too chaotic and the brain cannot hold a pattern to be surprised against. The sweet spot in the middle is what musicians have always called groove — and it is the reason a track that sounds slightly 'wrong' is the one you cannot sit still through.

As the story goes, Fats Waller was bundled into a car by armed men in 1926, driven to a Chicago party, and discovered he was the surprise gift for Al Capone's birthday. He played for three days and left with his pockets full of hundred-dollar bills.

Waller was leaving a gig in Chicago when four men with guns pushed him into a car — he assumed he was about to die. Instead he was marched to a piano and told to play. The guest of honour, delighted, kept him there for three days on champagne and food, and the guests stuffed cash into his pockets as tips. The tale comes chiefly from his son Maurice's account rather than any police record, so historians file it as very probably true rather than proven. Either way, Waller was one of the great showmen of the age — 'Ain't Misbehavin'' is his — and he apparently went home a good deal richer than he expected to.

In 1898 a struggling writer published a novel about the largest liner ever built — the Titan — striking an iceberg on an April night in the North Atlantic and going down with most aboard, for want of lifeboats. The Titanic sailed fourteen years later.

The parallels are hard to shake off: both ships were the largest afloat, both were called practically unsinkable, both carried far too few lifeboats, both were running fast through icy water on the northern route, and both names differ by four letters. Robertson was a former merchant sailor, and the likeliest explanation is expertise rather than prophecy — he knew the size ships were heading towards, knew the lifeboat regulations were inadequate, and knew the North Atlantic. He wrote the disaster the industry was building for itself. After 1912 the book was hurriedly reissued, and it has never quite been read as fiction since.

Q1548
WonderHistory

Violet Jessop was aboard the Olympic when it was rammed, aboard the Titanic when it sank, and aboard the Britannic when it went down too. She survived all three and kept going to sea for another thirty years.

Jessop was a stewardess on the Olympic in 1911 when a warship struck it, a stewardess on the Titanic in 1912 when she was put into a lifeboat holding a stranger's baby, and a nurse on the hospital ship Britannic in 1916 when it hit a mine in the Aegean. Sucked towards the Britannic's still-turning propellers, she jumped from her lifeboat and struck her head on the keel — an injury she later credited a thick head of hair with softening. She went back to work on liners and retired only in the 1950s, to a cottage in Suffolk.

WonderHistory

Tsutomu Yamaguchi was on a business trip in Hiroshima on 6 August 1945. Burned and half-deaf, he travelled home the next day — to Nagasaki, arriving in time for the second bomb.

An engineer for Mitsubishi, Yamaguchi was three kilometres from the Hiroshima hypocentre. He made it back to Nagasaki and was describing the blast to a disbelieving supervisor on 9 August when the second flash filled the window. He lived to 93. In 2009 Japan formally recognised him as the only official double survivor — though others were caught by both — and he spent his last years speaking against nuclear weapons, saying his survival appeared to have been given to him as a task.

The American Civil War opened with shells landing on Wilmer McLean's Virginia farm. He moved his family 190 km away to escape it — and four years later the surrender was signed in his front parlour.

In July 1861 the First Battle of Bull Run was fought across McLean's land; a shell is said to have come down through his kitchen. A grocer with no wish to be at the centre of a war, he moved south to the quiet village of Appomattox Court House. On 9 April 1865, officers looking for a suitable room knocked on his door, and Lee surrendered to Grant in his parlour. Souvenir-hunting officers then stripped the furniture and carried it off, some of them leaving money on the floor as they went.

Q1551
WonderHistory

Abraham Lincoln's son was pushed off a crowded train platform and pulled back to safety by a stranger. The stranger was Edwin Booth — brother of the man who would shoot his father.

Robert Todd Lincoln told the story himself in a letter of 1909. Waiting for a sleeping-car ticket at Jersey City, he was pressed against a moving carriage and dropped into the gap; a hand seized his collar and hauled him out. He turned and recognised Edwin Booth, the most celebrated American actor of the age. Neither knew what was coming. Within about a year or two Edwin's younger brother John Wilkes Booth shot the president at Ford's Theatre — and Edwin, told later of the rescue, is said to have taken some comfort from it.

In 1954 Ann Hodges was asleep on her sofa in Alabama when a 4-kilogram rock from space came through the ceiling, bounced off her radio and struck her hip. She is the only person confirmed to have been injured by a meteorite.

The meteorite was around 4.5 billion years old and had split in the atmosphere; the other piece landed miles away. Hodges was left with a spectacular bruise and, almost at once, a legal fight — her landlady claimed the rock belonged to the house. Hodges eventually kept it for a $500 settlement and later gave it to the Alabama Museum of Natural History. The attention exhausted her. Given how much of Earth is ocean and empty ground, the odds of a stone that has crossed the Solar System finding a sofa are almost past arithmetic.

WonderLiterature

In 1838 Edgar Allan Poe wrote a novel in which shipwrecked sailors draw lots and eat the cabin boy, Richard Parker. Forty-six years later a real crew was rescued having done exactly that — to a cabin boy called Richard Parker.

Poe's only novel, The Narrative of Arthur Gordon Pym of Nantucket, contains the scene almost as a throwaway. In 1884 the yacht Mignonette sank in the South Atlantic and four survivors drifted for weeks; they killed and ate the seventeen-year-old cabin boy, whose name was Richard Parker. The case became R v Dudley and Stephens, the decision every English law student still reads on whether necessity can excuse murder. It is said a relative noticed the resemblance to Poe's book years later. The name resurfaced once more in Life of Pi, given to the tiger.

Roy Sullivan, a park ranger in Virginia, was struck by lightning seven separate times between 1942 and 1977 and survived every one. It cost him a toenail, his eyebrows, and several hats set on fire.

Sullivan worked in Shenandoah National Park, high ground in a region of violent summer storms, which goes some way to explaining the first strike or two. Seven is another matter — the odds of being hit even once in a lifetime are roughly one in fifteen thousand. He grew wary of storms and reported that people began to avoid standing near him. He kept the burnt hats. Guinness still lists him as the human being struck by lightning more times than any other on record.

For centuries nobody knew where birds went in winter — theories included hibernating in mud and flying to the Moon. In 1822 a stork landed in Germany with an African hunting spear through its neck, and the question was settled.

The bird had been speared in central Africa, survived, and completed its migration north with 80 cm of wood still through it. Germans call it the Pfeilstorch — the arrow stork. Until then, even serious naturalists had proposed that swallows overwintered in lake mud, and one seventeenth-century Englishman argued birds flew to the Moon. Roughly two dozen more arrow storks have turned up since, but the 1822 bird is the one that changed minds. It is still on display in Rostock, standing calmly with the spear through its neck.

Q1556
WonderHistory

In January 1919 a storage tank in Boston burst and released two million gallons of molasses. The wave was eight metres high, moved at around 56 km/h, and killed twenty-one people.

The tank had leaked so persistently that locals collected the drips, and it had been painted brown to hide the seepage. When it gave way it flattened buildings and buckled the elevated railway. Molasses is a non-Newtonian fluid: it moved fast enough to outrun people, then thickened as it cooled, so rescuers had to cut victims free. The court case that followed ran for years and helped establish that companies must answer for the structures they build. Residents insisted the harbour smelled sweet on hot days for decades afterwards.

Q1557
WonderHistory

In 1983 a Soviet early-warning system reported American missiles inbound. The duty officer, Stanislav Petrov, decided it was a malfunction and did not pass it up the chain. He was right.

The satellite system flagged five launches from the United States. Petrov's job was to report; protocol pointed towards retaliation, and Cold War tensions were at their sharpest in years. He reasoned that a genuine first strike would involve hundreds of missiles, not five, and called it a false alarm — with no way of being certain and minutes to decide. The cause turned out to be sunlight glinting off high cloud into the satellite's sensors. He was quietly reassigned rather than decorated, and the story only emerged in the 1990s.

Q1558
WonderHistory

On Christmas Eve 1914, soldiers on the Western Front heard carols coming from the opposing trench. By morning thousands of men had climbed out unarmed to swap cigarettes, bury their dead, and in a few places kick a football about.

It was never ordered and never universal — the truce held along parts of the British and German line, while elsewhere the fighting carried on. Letters home describe German troops setting candles on trench parapets, then singing, then calling across. Football did happen, though the tidy image of an organised match is mostly later invention; the reliable accounts are of scratch kickabouts on frozen ground. Commanders on both sides moved quickly to stop it recurring. The war had four years still to run.

Q1559
WonderHistory

The US Army ran a secret unit of artists, designers and sound engineers who fought the Second World War with inflatable tanks, recorded troop noise and fake radio traffic. They staged more than twenty deceptions and are thought to have saved thousands of lives.

Roughly 1,100 men, many recruited from art schools and advertising, could impersonate a division of 30,000. They inflated rubber tanks and lorries, played recordings of armoured columns through enormous speakers audible for miles, and sent radio chatter to be intercepted. Fashion designer Bill Blass and painter Ellsworth Kelly served among them. The work stayed classified for decades; the unit finally received the Congressional Gold Medal in 2024, by which time only a handful of its members were alive to accept it.

Q1560
WonderHistory

In 1943 British intelligence dressed a corpse as a Royal Marines officer, chained a briefcase of fake invasion plans to his wrist, and floated him off the coast of Spain. Hitler moved his defences to the wrong island.

The body was that of Glyndwr Michael, a homeless Welshman who had died in London. Given the identity 'Major William Martin', he was supplied with letters, a photograph of a fiancée and used theatre tickets to make the life convincing. The documents suggested the Allies would land in Greece and Sardinia, not Sicily. The Germans took the bait and thinned their Sicilian defences. Michael's grave in Huelva now carries a note recording his real name — the man who never existed, and did.

Q1561
WonderHistory

In December 1900, a relief boat reached a lighthouse in the Outer Hebrides to find the lamp unlit, the table set, and all three keepers gone. No trace of them was ever found.

On the island of Eilean Mòr, everything was in order except the men. Two sets of oilskins were missing and one was left behind, and the logbook recorded severe storms — though weather records from nearby show the days were calm. The likeliest explanation is prosaic and grim: a freak wave sweeping the western landing while the men secured equipment, which would explain why one left without his coat. That has not stopped a century of speculation. The lighthouse was automated in 1971 and still stands.

The 1904 Olympic marathon was run in searing heat on dust roads with one water stop. The first man home had ridden 18 km in a car; the actual winner was carried over the line, having been dosed with strychnine and brandy by his own trainers.

Of 32 starters, 14 finished. Fred Lorz was hailed the winner before officials learned he had hitched a lift when his legs gave out, then rejoined on foot. Thomas Hicks was given strychnine — a stimulant in tiny doses, a poison in larger ones — mixed with brandy and egg white, and finished barely conscious. A Cuban runner, Félix Carvajal, had lost his money gambling, ran in cut-off trousers and street shoes, and stopped to eat orchard apples that made him ill. He still came fourth.

Q1563
WonderHistory

In 1847 Ignaz Semmelweis worked out that doctors were carrying death from the mortuary to the maternity ward on their hands. Washing them cut deaths tenfold. His colleagues rejected the idea, and he died in an asylum.

At the Vienna General Hospital, the ward staffed by doctors had a death rate several times that of the ward staffed by midwives. Semmelweis noticed the doctors came straight from performing autopsies, ordered handwashing in chlorinated lime, and watched mortality collapse. He could not explain why it worked — germ theory was still years away — and the profession took the implication, that they were the cause, as an insult. He was dismissed, declined, and died at 47 of an infection. Lister and Pasteur proved him right within two decades.
