Mangroves cover less than one percent of the tropics but store three to four times more carbon per hectare than inland rainforests. The reason sits under the trees, not in them: waterlogged, oxygen-starved peat that can hold organic carbon for thousands of years.
On 28 September 1969, a fireball dropped fragments of a black, carbon-rich meteorite over Murchison, Victoria. Inside were silicon carbide grains that formed inside dying stars about 7 billion years ago — roughly 2.5 billion years before the Sun existed. They are the oldest solid materials ever held in a human hand.
In 2005, Kazakhstan finished a 13-kilometre earthen dam across the Berg Strait for $86 million. Within a few years the North Aral rose 12 metres, salinity halved, and fishing boats returned to a port that had watched the shoreline retreat 100 kilometres over four decades.
In May 1952, Rosalind Franklin exposed a single hydrated DNA fibre to X-rays for more than 60 hours in a King's College basement. The image she developed — Photo 51 — showed a diffraction cross so clean the double helix was visible before any model existed.
Voyager 1 transmits from interstellar space on roughly 22 watts — less than a hallway bulb — thanks to decaying plutonium, a JPL team rationing every watt, and Deep Space Network dishes sensitive enough to catch a signal a tenth of a millionth of a billionth of a watt strong.
