How did a country whose forests held just 6 cubic metres of standing wood per hectare after colonial logging and war rebuild them to more than 160 within a single lifetime?
South Korea rebuilt forest cover from near-total collapse in 1955 to roughly 63 percent of national land today, through an 11-billion-tree state programme launched in 1973 and a nationwide switch from firewood to coal briquettes.
How did a conifer thought extinct for two million years turn up alive in 1994 within 200 kilometres of a city of 3.7 million people?
Why did a Bay of Bengal delta nation, after a 1991 cyclone killed some 138,000 people, plant hundreds of kilometres of salt-tolerant coastal forest instead of building higher sea walls?
How does a single tree colony in the American West cover roughly 106 acres, weigh around 6,000 tonnes, and share one root system that makes it a contender for the heaviest organism alive?
The Parker Solar Probe now passes within 6.1 million kilometres of the Sun's surface at 692,000 kilometres per hour, fast enough to cross the continental United States in about 20 seconds, shielded by a carbon-composite heat shield only 11.4 centimetres thick
Why does a cumulus cloud drifting overhead often weigh several hundred tonnes and still hang in the sky as if it weighed nothing at all?
In 1868, astronomers watching a solar eclipse from India detected a bright yellow spectral line in the Sun's atmosphere that matched no known element on Earth, and helium became the only element in the periodic table discovered on another world before it was found on this one
How does a coastal forest that covers less than one percent of the tropics store up to four times more carbon per hectare than the rainforests inland?
The Murchison meteorite that fell on a Victorian farming town in 1969 contains silicon carbide stardust that formed in the outflows of dying stars up to 7 billion years ago, making it older than the Sun itself by roughly 2.5 billion years
How did a Central Asian sea that lost roughly 90 percent of its water in 40 years claw back a northern lobe deep enough for fishing boats to return?
In 1952, Rosalind Franklin exposed a hydrated DNA fibre to X-rays for over 60 hours in a King's College basement, and the resulting image — Photo 51 — showed a dark diffraction cross so unambiguous that the helix was visible before any model had been built
