According to a LiveScience article from 2013, scientists discovered there is actually a gene called ABCC11, which is responsible for producing body odor. Those who produce a dry version of earwax also lack the same bacteria living in armpits causing odor. The reasoning behind this theory is because those who produce dry earwax also don’t produce the protein that transports sweat out of pores in our armpits, which attracts bacteria that cause body odor.

This phenomenon is called a whale fall. A whale fall is the carcass of a dead whale that has fallen into the abyssal zone (deeper than 1.000 m, or 3.300 ft) on the ocean floor. This can create a local ecosystem that supplies sustenance to deep-sea organisms for decades. This is unlike in shallower waters, where the carcass will be consumed by scavengers over a relatively short period of time.

Microsoft has included the game Solitaire as part of its Windows product line since Windows 3.0, starting from 1990.

For years, the scalpers got the tickets and would scalp the front row for ridiculous amounts of money. Our tickets are cheap, under $100, some in the $80s, the highest is about $150.

While apes can learn sign language and communicate using it, they have never attempted to learn new knowledge by asking a question. They don't realize that humans or other apes can know things they don't. It's a concept that separates mankind from apes.
