Mind & Meaning
Researchers who followed nearly 7,000 Dutch adults for nine years found that both passive and active social media use were linked to rising loneliness over time — and the relationship ran in both directions
Constellations
Arno Penzias and Robert Wilson spent months at Bell Labs in New Jersey convinced the faint hiss in their antenna was a fault — pigeons, droppings, loose rivets, all ruled out — before a Princeton physicist told them it was the oldest light in the universe, the afterglow of the Big Bang.
Human Behaviour
Vitamin B12 is synthesised only by bacteria and archaea — and the human liver stores roughly a three-year supply before deficiency shows in the blood
Human Behaviour
The human body synthesises roughly 1 gram of creatine a day in the liver and kidneys — and stores about 95% of it inside skeletal muscle
Spacemart
Space lawyers have a name for satellites claimed on paper years before a single one launches: they call them paper satellites, and the earliest filing quietly locks out everyone who comes later
Constellations
By mid-2026 a single company, SpaceX, had more than 10,000 Starlink satellites circling the Earth — roughly two of every three active satellites in orbit now belong to one man's network
Aerospace
In space, the human heart shrinks within days as gravity's load disappears — a small 2001 study found an average 12 percent drop in left-ventricular mass after a 10-day shuttle mission, with rebound over days to weeks on the ground
Mind & Meaning
Astronauts returning from long missions can initially struggle to stand, walk, and judge the weight of ordinary objects — because the brain must relearn a gravitational world it once treated as automatic
Outer Planets
Juno survives repeated dives through Jupiter’s lethal radiation belts by hiding its electronic brain inside a 180-kilogram titanium vault — because an ordinary spacecraft computer would quickly fail in the storm of high-energy particles
Deep Space
When Voyager 1 launched in 1977, each of its main computer systems had less than 70 kilobytes of memory — smaller than a typical phone photo — and that 1970s hardware is still carrying out commands from Earth nearly five decades later
Cosmology
Most of every galaxy is made of matter nobody has ever seen, detected, or explained — and the clearest early proof came from an astronomer named Vera Rubin, who simply measured how fast the outer stars of galaxies were spinning
Technology
NASA’s Deep Space Network can detect a signal as weak as a billionth of a billionth of a watt from spacecraft billions of kilometres away — using 70-metre dishes to pull a technological whisper out of the noise of space
Exo Life
Researchers froze the simplest amino acid to nearly minus 260°C and bombarded it with radiation that mimics cosmic rays — and it formed peptides, the building blocks of proteins, under conditions that exist before stars and planets are born
Flora And Fauna
A queen honeybee can live for several years, while worker bees may live for only six weeks in summer — and biologists still cannot fully explain the difference, because queens and workers share the same basic genome and are separated mainly by what they were fed as larvae
