The Brain That Turned to Glass

A victim of Mount Vesuvius’s AD 79 eruption left behind something researchers had never documented before: vitrified human brain tissue. A 2025 study suggests an extremely hot, short-lived ash cloud heated the tissue above 510°C before rapid cooling preserved it as organic glass.

The Maze Solver With No Brain

Physarum polycephalum is a single-celled slime mold that can navigate mazes, make efficient networks and avoid routes it has already explored, all without neurons. So who needs a brain? Apparently not everyone.

The Universe Has a Left-Handed Streak

In experiments designed by physicist Chien-Shiung Wu and colleagues, certain radioactive decays did not behave like their mirror images. Their discovery overturned the assumption that parity symmetry always holds: the weak nuclear interaction distinguishes left from right.

The Barefoot Sprinter From Prehistory

Ancient footprints near Lake Mungo in Australia preserve evidence of people moving across a wet landscape thousands of years ago. Some estimates based on stride length suggest remarkable running speeds, but exact speeds and the date depend on interpretation.

The Vine That Might Be a Copycat

Chile’s Boquila trifoliolata has been reported to grow leaves resembling neighboring plants. Researchers proposed several explanations, even an intriguing “plant vision” hypothesis. But a 2026 preprint could not reproduce the claimed mimicry under controlled conditions. It is a fascinating open question, not proof that plants can see.

The Old Map Used as a Draft Stopper

A centuries-old world map attributed to cartographer Joan Blaeu reportedly survived after being stuffed into a chimney in a Scottish castle. An extraordinary recycling choice, though the discovery details need confirmation from a museum or conservator before we treat the story as fully verified.
