5 checked facts in this niche — each with its receipts.
Natural diamonds crystallize roughly 90 to 150 miles down in Earth's mantle under immense heat and pressure, far deeper than any coal seam has ever existed, and many diamonds are over a billion years old — older than the first land plants that would eventually become coal.
A banana is botanically a berry while a strawberry is not, because a true berry develops from a single ovary with its seeds embedded in the flesh.
A 2014 study found water chemically bound inside ringwoodite in Earth's mantle transition zone, suggesting the deep mantle may hold a comparable volume of water to the oceans — bound in mineral structure, not as liquid.
Tyrannosaurus rex lived closer in time to humans than to Stegosaurus: Stegosaurus went extinct around 150 million years ago and T. rex around 66 million years ago, so more time separated those two dinosaurs than separates T. rex from us today.
Octopuses have three hearts: two branchial hearts that pump deoxygenated blood through the gills, and one systemic heart that pumps oxygenated blood to the rest of the body — and the systemic heart stops beating entirely while the animal swims, which is why octopuses prefer crawling.
