Human Behaviour
Post-it Notes were invented in 1968 by a chemist named Spencer Silver trying to develop a super-strong aerospace adhesive — and the weak glue he accidentally produced instead sat unused for six years until a colleague named Art Fry needed something to anchor the bookmarks in his church hymnal
Mind & Meaning
The Taj Mahal was built by an Indian emperor named Shah Jahan as a tomb for his late wife — and the project cost so much that his own son seized the throne and imprisoned him for the last eight years of his life in a fortress approximately 2.5 kilometres upstream along the same river, where his only view was the tomb itself
Science
Two South Korean companies named Samsung Electronics and SK Hynix now manufacture roughly two-thirds of the memory chips inside almost every digital device on Earth — produced inside a country whose 1953 per-capita income was lower than Somalia's or Haiti's
Technology
In 1971, the founder of Hyundai named Chung Ju-yung walked into the London headquarters of Barclays Bank carrying a photograph of an empty Korean beach and a 500-won banknote depicting a 16th-century Korean ironclad warship — and persuaded the British lender to finance the construction of the shipyard that within just over a decade would become the largest shipbuilding operation on Earth
Aerospace
Humanity has spent well over a billion dollars bringing asteroid pieces back to Earth — and all the material returned by Hayabusa, Hayabusa2, and OSIRIS-REx combined weighs about 127 grams, less than a small apple.
Science
Microsoft’s experimental AI diagnostic system, MAI-DxO, correctly solved up to 85.5% of 304 difficult medical cases adapted from the New England Journal of Medicine — far above the 20% average achieved by 21 experienced physicians under benchmark conditions.
Earth Observation
On 29 April 2020, a single bolt of lightning stretched 768 kilometres across Texas, Louisiana, and Mississippi in one continuous flash, far enough to reach from New York City to Columbus, Ohio before the thunder from its first end had finished rolling
Earth Observation
Satellites can now tell a palm oil plantation from native rainforest by the precise angle its fronds bend the sunlight, reading the near-perfect planted lattice against the chaos of wild canopy — and the European Union's 2023 deforestation regulation now leans on their ability to do exactly that
Science
In the mudstones of a place called Bright Angel, Perseverance detected complex carbon molecules hundreds of times across two rocks, a find researchers called the only detection of macromolecular carbon on a natural rock surface on Mars
Constellations
Euclid, the European telescope built to map the dark universe billions of light-years away, spent a single 26-hour stretch staring into the crowded center of the Milky Way and resolved more than 60 million stars, handing NASA's Roman mission a reference map for the planet hunt it begins after launching in late August
Science
In July 2025, the ATLAS sky survey in Chile spotted a faint comet racing through the solar system at roughly 130,000 miles per hour — and follow-up orbit calculations quickly showed it was not bound to the Sun at all, but had arrived from interstellar space.
Science
Neuroscientists long believed you are born with all the neurons you will ever have — in 2025, researchers found newly formed neurons in the brains of adults as old as 78, overturning decades of settled thinking
Science
Shown its reflection in a mirror, a small reef fish scraped at a mark it could see only there, behaving as if it recognized itself - though the researchers stopped short of calling it self-aware
Aerospace
South Korea's military built a solid-fuel rocket to put spy satellites in orbit on short notice, and the full four-stage version is set to make its first flight
