A study found that octopuses rapidly change skin color and texture while sleeping, cycling through patterns used for camouflage when awake. Scientists believe this behavior resembles a REM like sleep state where the brain replays recent experiences. The discovery suggests complex neural activity during sleep in one of the ocean’s most intelligent animals.

Researchers successfully grew a flowering plant using seeds that had been buried in Siberian permafrost since the Ice Age. The seeds were preserved by prehistoric squirrels in underground burrows, protecting them from decay for tens of thousands of years. The experiment revealed how life can remain dormant for extreme lengths of time and still return when conditions allow.

An unusual characteristic of the platypus is the complete lack of a digestive sac that secretes acid. Evolution suggests this organ was lost because its diet—soft-bodied invertebrates—does not require the intense chemical processing that strong stomach acid provides. This unique anatomy makes the platypus, already famous for its bill and venom, an even stranger anomaly in the mammalian world and a perfect example of evolutionary adaptation to a specific niche diet.

The Svalbard Global Seed Vault is a secure, fortified structure carved into the Arctic permafrost, making it resistant to natural disasters and power failures (the permafrost acts as a natural freezer). It holds duplicate "backup" copies of crop seeds from collections worldwide. This global effort is humanity's insurance policy, ensuring that the genetic diversity necessary to restart agriculture survives any potential worldwide catastrophe.

The New York City Subway is one of the world's most extensive public transport systems, but what most riders don't see is the hidden city below the active lines. Beneath the streets of Manhattan and the outer boroughs lies a sprawling network of abandoned stations, decommissioned platforms, and miles of unused track. These tracks were built during the early 20th century, anticipating rapid expansion and rival private lines. For example, below City Hall is a cathedral-like station with vaulted ceilings and brass chandeliers that hasn't seen a passenger since 1945. This extensive ghost network represents a massive, unused urban relic—a testament to grand, forgotten ambition—hidden just feet below millions of commuters every day.
