What’s a 11-letter concept shared by crossword puzzles and avalanches, and starts with the letter “P?” According to one physicist, the answer is simple: Percolation. “When a statistical physicist looks at a partially solved crossword puzzle, she or he sees immediately a percolation problem: Is there a spanning path consisting of fully solved words?” writes […]

At 1.2-million-years-old, a newly uncovered Antarctic ice core represents the oldest known ice on the planet. The 1.7 mile-long ice core was recovered from over 9,000 feet (2,800 meters) deep underground, where the Antarctic ice sheet meets bedrock. The drilling was completed earlier this month at a location called Little Dome C near the Concordia

New aerial images of the Dmanisis Gora settlement, located in present-day Georgia, show a large land area well guarded by steep gorges and plastered with various stone structures and

Airline companies must adhere to the Federal Aviation Administration’s detailed safety regulations (approximately 403 pages’ worth of them) before their planes are allowed to transport passengers. But nowhere in those guidelines is there an explicit cap on cabin temperatures during boarding outside an “improbable failure condition”—an omission that continues to result in sweaty, potentially dangerous

The lush forests of Switzerland are not the first place that bioluminescent organisms come to mind. However, a forest in a Zurich neighborhood is home to a bioluminescent mushroom that glows green. The mushroom’s newly discovered bioluminescence is described in a study recently published in the journal Mycoscience. Get the Popular Science newsletter Breakthroughs, discoveries,

Ants primarily rely on their fine-tuned olfactory sense to differentiate between the smell of members of their own family (i.e. safe ants) and ants from other colonies. A familiar scent while out foraging, for example, allows a worker

The glymphatic system–the brain’s waste disposal mechanism–flushes away excess cerebrospinal fluid containing harmful proteins that otherwise build up slowly in the brain. Accumulation of these proteins has been associated with increased risk of conditions like Alzheimer’s Disease. In a new paper published January 8
