More than 2,200 years before satellites, GPS and space missions revealed the Earth’s true size, an ancient Greek scholar calculated the planet’s circumference using nothing more than a stick, sunlight and basic geometry. Around 240 BCE, Eratosthenes, the chief librarian of the Library of Alexandria, carried out one of history’s most brilliant scientific experiments. By…
Forest bathing sounds like an ancient tradition, but it is actually younger than the personal computer. The practice known as shinrin-yoku was coined in Japan in 1982, not passed down through centuries. It began as a public health idea rather than a spiritual one, aimed at a country that was mostly forest but rapidly urbanising,…
Asteroid breakup 800 million years ago may have triggered impacts on Earth, the Moon and Mars (AI photo) A massive asteroid that broke apart around 800 million years ago may have sent a huge number of rocky fragments towards Earth, the Moon and Mars, according to a new study led by researchers at the Southwest…
Image(s): Guinness World Records For Wally Funk, the dream of becoming an astronaut began long before women were welcomed into America’s space programme. In 1961, the gifted pilot completed the same gruelling medical and psychological tests given to NASA’s first astronauts as part of the pioneering Mercury 13 programme. Despite outperforming many of her male…
This might be the closest humans have come to finding another planet that can support life. In a shocking discovery, astronomers have detected an atmosphere around an Earth-like, rocky planet about 48 light-years away.The planet, called LHS 1140 b, is orbiting in the habitable zone around its star meaning that it is at the right…
High above the Amazon rainforest, invisible currents of water vapour move through the sky in narrow, fast-flowing bands, carrying a volume of moisture that dwarfs even the largest rivers on the ground below. Scientists call this phenomenon an atmospheric river, sometimes nicknamed a flying river when it occurs above dense forest, and unlike a conventional…
A person demonstrates Japan’s TRUSCO Do Reimon Box, a walk-in cooling booth. As record-breaking heatwaves become more frequent around the world, keeping outdoor workers safe has become an increasingly urgent challenge. Japan may have come up with an unusual solution. A Japanese company has developed what many are calling a “human refrigerator”, a walk-in cooling…
Pythagoras (Image: Wikipedia) Humans depend entirely on the natural world, and yet the relationship has always been tangled with contradiction, admiration for animals sitting right alongside routine cruelty toward them. A line attributed to Pythagoras names that contradiction directly. “As long as Man continues to be the ruthless destroyer of lower living beings, he will…
Koalas nearly went extinct before humans arrived, DNA study reveals A major genetic study has found that koalas almost became extinct about 100,000 years ago because of major climate changes, long before the first humans reached Australia.By studying the DNA of hundreds of koalas, an international team of researchers found that every koala alive today…
Seasonal gene switch locks fruit flies in winter mode Scientists studying how animals survive the winter have discovered that fruit flies completely rebuild their internal biological clocks to switch into a separate seasonal mode. For context, a fruit fly is a tiny insect that feeds on ripe, rotting, or fermenting fruits and vegetables. They are…
