Twenty metres under a Romanian wheatfield, Movile Cave holds 35 species found nowhere else on Earth — a food web powered by bacteria that eat hydrogen sulphide instead of sunlight, sealed off from the surface for roughly 5.5 million years.
A volcanic lake in Cameroon turned into a lethal trap when the invisible gas trapped beneath its surface suddenly rose to the top, suffocating thousands in their sleep.
Astronauts on six-month ISS missions come home up to 3 percent taller as their spinal discs expand without gravity's compression — a temporary stretch that quietly reverses within months, often bringing back pain in its wake.
Saturn's moon Titan is the only other body in the solar system with a working weather cycle on its surface — rain, rivers, and seasonal lakes made of liquid methane at minus 179 degrees Celsius. Here's how the machinery works, and why its rivers refuse to build deltas.
In September 1928, a contaminated petri dish in a cluttered London lab produced the halo of dead bacteria that launched the antibiotic era — and the story of how Alexander Fleming's messy bench changed medicine is stranger than the schoolbook version.
