Italian architect Giuseppe Fiorelli discovered many of these had left holes in the ash layers after collapsing in 1863.

Aldrin was reasonably irritated after risking his life and making significant sacrifices to complete his mission. He was doing fine until the stranger labelled him a coward, a liar, and a thief. At that time, Aldrin, then 72, punched his sidewalk interrogator in the face. The District Attorney's Office in Los Angeles declined to file charges against Aldrin.

A command entered in the "master machine" where the animation for Toy Story 2 was stored deleted 90 percent of the work the Pixar team had done on it. As Mental Floss describes, "A plan was quickly hatched to restore the data from a regular backup, which meant that only half a day of work would have been lost. But the backup system had failed. Pixar, incredibly, did not have a copy of the Toy Story 2 files on its servers." Fortunately, the film's technical director had a copy she had been working on from home, and much of it was restored.

This is an attempt to reduce the spread of bacterial diseases in medical settings.

The domestic silkworm Bombyx mori produces the majority of the world's silk, subsisting almost entirely on mulberry leaves. After reaching adulthood, the silkworm produces a fine fibre that is wound into a compact cocoon. Fibroin, which makes up the core filament, and sericin, a gooey substance that holds it all together, are the two main proteins that make up the fibre. The individual filaments of silk are slowly and carefully unwound from the cocoon and reeled together to create one very long, continuous strand of silk yarn. Silk is an entirely natural fabric if it is left undyed and untreated.
