- X-ray scans have revealed this grapefruit-sized lump is actually a 30,000-year-old mummified ground squirrel from the ice age.
- A gold miner found the mysterious fur ball in 2018 in the Klondike gold fields near Dawson City, Yukon, according to the Yukon Beringia Interpretive Centre.
- "It's not quite recognizable until you see these little hands and these claws, and you see a little tail, and then you see ears," Grant Zazula, a Yukon government paleontologist, said.

- Scientists have stitched together the most high-resolution map yet of the underlying geology beneath Earth's Southern Hemisphere, revealing something previously undiscovered: an ancient ocean floor that may wrap around the core.
- This thin but dense layer sits around 2,900 kilometers (1,800 miles) below the surface, where the molten, metallic outer core meets the rocky mantle above it. This is the core-mantle boundary (CMB).

- An ethereal blue glimmer just below the waterline has lured scientists to three new glowing species of marine bristle worm (polychaetes).
- Their genus name, Polycirrus, means 'many tendrils' in Latin.
- Until now, we knew of only four species of Polycirrus with the ability to bioluminesce.
- In addition, there were only two species of Polycirrus described in Japan. This new discovery, led by marine worm expert Naoto Jimi, adds three new species to each tally.

- A long-lost letter from the scientist to an inquiring engineer in 1949 turned out to be extraordinarily prescient in the fields of biology and physics.
- "It is thinkable that the investigation of the behavior of migratory birds and carrier pigeons may someday lead to the understanding of some physical process which is not yet known," Einstein wrote in a letter.
