A parasitic barnacle called Sacculina injects itself into a crab, grows a root system through its host's body, and chemically rewires the crab's brain to care for the parasite's eggs as if they were its own, even castrating male crabs so they behave like females tending a brood.

Sacculina carcini enters a shore crab as a droplet of cells, grows rootlets through the host's body, castrates and feminises males, and hijacks the crab into raising the parasite's eggs as if they were its own brood.

Marie Curie processed several tonnes of pitchblende by hand in a leaky Paris shed with no floorboards, boiling and filtering the ore for nearly four years to isolate about a tenth of a gram of radium chloride, whose samples glowed faintly in bottles across the shed and slowly damaged her fingertips

Between 1898 and 1902, Marie and Pierre Curie processed tonnes of pitchblende by hand in a leaky Paris shed to isolate roughly a tenth of a gram of radium chloride — a luminous pinch of salt that changed medicine and slowly destroyed her hands.

Friction normally slows things down. But atmospheric drag makes a satellite lose orbital energy and fall into a lower orbit — and lower orbits are faster. So although drag initially slows the spacecraft, the resulting orbital decay can leave it moving faster around Earth. Scientists were analysing this effect as early as 1958.

Atmospheric drag always removes orbital energy, but gravity can leave a decaying satellite moving faster after it falls into a lower orbit.

A single cotton T-shirt requires approximately 2,700 litres of water to produce, the equivalent of one person's drinking water for two and a half years, and the global fashion industry now consumes approximately 79 billion cubic metres of fresh water annually, much of it drawn from regions already facing severe drought

The fashion industry's water crisis is worse than you think—and cotton isn't even the main culprit.

NASA's Psyche spacecraft used Mars as a gravitational slingshot on 15 May 2026, skimming within 2,864 miles of the surface and walking away 1,000 miles per hour faster — burning no fuel in the process — on its way to an asteroid that may be the exposed metal core of a dead planet

NASA's Psyche probe gained 1,000 mph from Mars without using propellant during the flyby. The physics is exact, while the asteroid's core identity remains a hypothesis.

The Voyager Golden Record carries a small sample of uranium on its cover, placed there so that whoever finds it can measure the decay and work out how long it has been drifting — a built-in clock for a message engineered to last around a billion years.

Voyager’s Golden Record cover carries a tiny uranium-238 reference whose decay can reveal elapsed time, independently checking its pulsar-map date.

Terra Daily

Earth science, climate impacts, ecosystems, agriculture, forests, and the broad environmental changes shaping life on a changing planet.

Climate Science

How does a city-state of six million people meet roughly 40 percent of its water demand by putting treated sewage back through the tap, and why did it start doing this in 2003 rather than desalinate more seawater?

Climate Science

Honey sealed inside Egyptian tombs more than 3,000 years ago can survive intact, dark and crystallised rather than rotten, because honey's low water content, acidic pH around 3.9, and the trickle of hydrogen peroxide produced by bee enzymes create an environment where almost no microbe can grow

How did a dust-built plateau larger than France cut the sediment pouring into a river from 1.6 billion tonnes a year by more than 80 percent over four decades?

We tend to think of AI as a software problem, weightless and waterless, but even a 100-word email written with ChatGPT has been estimated to require roughly a bottle’s worth of water once data-centre cooling and electricity generation are counted — and scaled to global demand, researchers project AI could withdraw 4.2 to 6.6 billion cubic metres of water a year by 2027, roughly half the United Kingdom’s annual freshwater withdrawals.
