Titan reproduces the sequence of a terrestrial weather cycle using liquid methane and ethane over a crust where water ice behaves as rock.
A decade-long push to revive the Chesapeake Bay's oyster reefs hit its target—and then some—planting billions of creatures across thousands of acres.
A species hunted to extinction in its native land found salvation in a British estate, then returned home to transform China's wetlands into a thriving refuge.
A species hunted to near extinction in Italy's mountains has staged an unlikely comeback—and scientists finally understand what made the rescue work.
In April 2025 the first of 23 roughly 22,000-tonne concrete caissons for Belgium's Princess Elisabeth Energy Island were placed about 45 km offshore; reported cost estimates have since climbed towards €7 billion.
In September 1994, NSW parks officer David Noble abseiled into a slot canyon 150 kilometres from Sydney and walked past a stand of tall trees with bubbled bark that matched 90-million-year-old fossils — the Wollemi pine, a species presumed extinct since long before the first humans.
The 1908 Tunguska explosion flattened 2,150 square kilometres of Siberian forest without leaving a crater. Leonid Kulik's expeditions reconstructed the event entirely from the radial pattern of felled trees — and a century later, the airburst remains the largest cosmic impact in recorded human history.
Microsoft's Project Silica has written 4.8 terabytes of data into a 2mm-thick sheet of borosilicate glass using femtosecond lasers, encoding it as 301 layers of 3D voxels that machine learning models read back — and accelerated ageing tests suggest the data will still be intact in 10,000 years.
In 1930, a physicist at the University of Queensland cut open the stem of a funnel filled with pitch to show his students that some solids are actually very slow fluids. Ninety-six years later, only nine drops have fallen — and no human has ever witnessed one detach.
Cymothoa exigua slips through a fish's gills, drains the blood vessels feeding the tongue until the organ withers away, and then hooks itself into the empty stump — the only known animal that functionally replaces a host organ.
Beneath the mud lies a carbon bomb that makes rainforest destruction look modest by comparison.
Pando has been regrowing itself from the same root system for somewhere between 16,000 and 80,000 years. That range is not a rounding error, and researchers still cannot narrow it.
After the 1995 floods forced 250,000 people to evacuate, the Netherlands stopped raising its dikes and instead spent €2.3 billion giving its rivers more room. Here is how the Room for the River program actually worked — and what happened when the water came back in 2021.
During the Apollo 11 mission, Michael Collins spent about 21 hours alone in lunar orbit aboard Columbia, losing radio contact with Earth for roughly 48 minutes of every orbit as he passed behind the far side of the Moon — a physical isolation no human has matched since.
After a 1991 cyclone killed roughly 138,000 people, Bangladesh planted around 200,000 hectares of salt-tolerant keora mangroves along its Bay of Bengal coast. When a comparable storm hit in 2007, the death toll fell to about 3,500.
China's Loess Plateau shed roughly 1.6 billion tonnes of silt a year into the Yellow River for millennia. Then Grain-for-Green, check dams and terracing cut that discharge by nearly 30 billion tonnes cumulatively in two decades — with hydrological costs that are still being counted.
