1880 Washington, D.C. • In a study published in Nature Photonics on 2 June 2026 (DOI 10.1038/s41566-026-01916-0), a Monash University team in Australia led by Dr Chi Li reported a single integrated chip that can generate, steer/route, and read information carried by light, the first device to perform all three functions on one chip. It uses atomically thin (two-dimensional) materials with engineered nanostructures and encodes information in a quantum property of light called the valley degree of freedom, part of an emerging field known as valleytronics, and it works at room temperature. Computing and communicating with light rather than electrons promises to be faster and far more energy efficient, attractive for power-hungry artificial intelligence and quantum machines. As Dr Li put it, 'What we've built is a complete on-chip system that can create, route and read this information with very high precision.' It is, in effect, the on-chip realisation of the idea Bell glimpsed in 1880: information carried on light.
In 1880, four years after the telephone, Alexander Graham Bell sent a human voice 700 feet across the rooftops of Washington with no wire at all, riding on a beam of sunlight. He called the photophone the greatest invention he ever made, greater than the telephone. The world had no use for it for a century. In June 2026, a chip that generates, steers, and reads information carried by light finally brings Bell's beam to the frontier of computing.

Imperial Russia, 1881 • The 2026 US-Israeli regime-change war on Iran, the killing of Supreme Leader Ali Khamenei, and the Revolutionary Guards' installation of his son Mojtaba amid a shift of power to the military-security apparatus.
In 1881 revolutionaries killed Tsar Alexander II, the reformer who had freed the serfs and who had signed Russia's first proto-constitution that very morning, certain his death would open the door to freedom. Instead it brought his harder son, the secret police, and decades of reaction. In 2026, a regime-change war has killed Iran's supreme leader, and the Revolutionary Guards have installed his son and tightened a harder, more militarised grip. The lesson of the canal is cold: the surest way to empower a dead man's hardest heirs is to kill him.

1868 England • A study published in PLOS Biology on 27 May 2026, 'Symbiotic bacteria may support calcium carbonate precipitation in the Gulf toadfish', led by Anthony Bonacolta at the University of Miami Rosenstiel School, found that the calcium carbonate pellets (ichthyocarbonates) which bony fish produce and excrete to handle the seawater they drink are not made by the fish alone. A gut bacterium, the vibrio Photobacterium damselae, is abundant in the fish gut and in the carbonate pellets and carries genetic machinery linked to carbonate production, suggesting a fish-microbe symbiosis. Fish carbonates, long studied by Martin Grosell's Miami group, are a recognised contributor to the ocean's carbonate budget and help buffer ocean chemistry as a carbon sink, a process that matters as rising atmospheric carbon dioxide drives ocean acidification. As senior author Martin Grosell put it, what was thought to be driven solely by the fish 'may actually reflect a close symbiosis between the fish and its gut microbial community.'
In 1868 Thomas Huxley held up a piece of ordinary chalk before a hall of working men and revealed that it was not a mineral at all but the packed skeletons of countless microscopic sea creatures: proof that life itself builds the rock and shapes the chemistry of the oceans. A century and a half later, scientists cutting open a common fish have found a hidden bacterial passenger helping it mint that same limestone, the smallest hands still quietly building and balancing the sea.

Byzantine Empire, 963 to 969 AD • Israel's 2026 crisis over ending the ultra-Orthodox (Haredi) exemption from military conscription, pitting the Supreme Court and a war-weary public against the religious community and the parties that protect it.
In 964 the warrior-emperor Nikephoros Phokas, conqueror of Crete, Cyprus and Antioch, tried to make the Byzantine Church share the burden of the empire's defence: he curbed the tax-exempt, service-exempt monasteries and asked that fallen soldiers be honoured as martyrs. The Church refused, he was murdered, and his law was undone. A thousand years later, Israel is fighting almost exactly the same battle over the ultra-Orthodox draft exemption, and history offers a sobering note: the exemption tends to outlive the reformer.

1920s Japan • A 2026 study led by Keith Koper at the University of Utah, published in The Seismic Record, reanalysed a magnitude 3.8 earthquake recorded on 24 February 1979 near Randolph, Utah at a focal depth of about 90 km (first flagged as anomalously deep by then-postdoc George Zandt) together with eight other suspected deep events in northern Utah and southwestern Wyoming, and confirmed all nine as continental mantle earthquakes at 68 to 90 km depth, beneath the crust. At those depths temperatures exceed 700 degrees Celsius and rock is expected to flow ductilely rather than fracture, and crucially these events occur outside any subduction zone, so the cold-slab mechanisms that explain Wadati's deep earthquakes do not apply. The team proposes that soft mantle flowing around the cold deep root of the Wyoming Craton concentrates strain enough to break, but the fundamental physics, in the words of the researchers, remains a mystery: 'How in the world can these things happen?'
In the late 1920s a Japanese weatherman named Kiyoo Wadati proved earthquakes happen hundreds of kilometres down, deep inside rock that was supposed to be too hot to break. The world ignored him for twenty years. A century later, beneath a quiet corner of Utah, scientists have confirmed nine earthquakes breaking ninety kilometres below a continent, where the rock should flow, not fracture, and where the explanation Wadati's deep quakes eventually earned does not apply at all.

Roman Britain, around 410 to 450 AD • President Trump's 2026 withdrawal of US forces from Germany and his floating of a NATO without the United States, and Europe's scramble to rearm and build a fallback defence it cannot quickly fully replace.
Around the year 410, with the legions gone, the Western emperor sent word that Rome could no longer defend Britain: see to your own defence. The abandoned province improvised, hiring Saxon mercenaries who soon turned on their employers and took the island. In 2026, as the United States pulls troops from Germany and floats a NATO without America, Europe is scrambling to build a defence of its own, and the oldest lesson of abandonment is waiting on the wall.

1917 to 1922, the Western Front and Cambridge • A study led by Lei Fang (University of Pittsburgh) with Xinyu Si, Filippo De Lillo and Guido Boffetta (University of Turin), 'Manipulating the direction of turbulent energy flux via tensor geometry in a two-dimensional flow' (Science Advances, 2025), drew wide science-press attention in early June 2026. By recasting the turbulent energy flux as a mechanical process and changing the geometry between the driving force and the flow in a thin layer of salt water driven electromagnetically, the team produced two-dimensional turbulence with either a forward (large to small) or an inverse (small to large) energy cascade. This challenges the assumption, standing since Kolmogorov in 1941, that the dimensionality of a system alone fixes the direction of its energy cascade, and the authors suggest it could eventually help steer ocean currents and improve climate forecasting.
In 1917 a Quaker pacifist named Lewis Fry Richardson computed the weather by hand in an army billet, and gave turbulence its enduring image: big whirls feeding little whirls, energy tumbling forever downhill from large to small. In 1941 Kolmogorov made that one-way arrow a law of physics. For more than eighty years the direction of the flow looked like a fact about the universe. In 2026 four physicists, in a tray of salt water stirred by magnets, ran the arrow backwards.

1768 Boston • The US-China tariff war of 2026 and the rerouting of Chinese trade through third countries such as Vietnam and Mexico, with Washington escalating enforcement against transshipment.
Boston, June 1768: the Royal Navy tows a smuggling sloop called Liberty out of the harbour and lights a riot. For thirty years Britain had let the colonies smuggle in peace; the day it chose to enforce its trade laws, it began to lose them. In 2026, as Washington walls off Chinese goods and chases the trade as it reroutes through Vietnam and Mexico, the same lesson is waiting on the dock.

1964 Oklahoma City • NASA's X-59 quiet supersonic demonstrator was expected to cross Mach 1 for the first time in early June 2026, engineering the sonic boom down to a quiet thump in a bid to overturn the 1973 overland supersonic ban that Operation Bongo helped create.
Oklahoma City, 3 February 1964: the United States government begins dropping 1,253 sonic booms on half a million of its own citizens, eight a day for six months, to prove they could learn to love the coming supersonic age. The experiment helped kill the American supersonic dream. 62 years later, NASA's X-59 is about to cross Mach 1 by doing the opposite: engineering the boom out of the airplane entirely.

July 1902 to December 1919, from Theodor Herzl's testimony before the British Royal Commission on Alien Immigration to the Aliens Restriction (Amendment) Act that sealed Britain's first peacetime immigration regime into permanent peacetime law • Brussels, 1 June 2026: EU concludes the trilogue on the Pact on Migration and Asylum (in force 12 June), creating third-country return hubs, expanded detention, biometric collection from children, a seven-state safe-country-of-origin list, and a €420M frontline fund.
Brussels, 1 June 2026: the EU Commission, Council and Parliament conclude the trilogue on the Pact on Migration and Asylum, creating third-country return hubs and expanded deportation powers. Britain's Aliens Act 1905, the first general peacetime immigration control of the modern British state, built the same architecture for a different generation of refugees, and used it in the 1930s to refuse the children of the people it was first written to keep out.
