Melanistic foxes are foxes with a rare genetic mutation that gives them a black coat. This coat creates a striking appearance that can make them look almost like a different species.

Many colour laser printers and photocopiers embed tiny, nearly invisible tracking dots on every page that act as a digital watermark identifying the specific machine. This technology was developed in the mid-1980s but not widely known to the public until 2004.

Some people with severe dementia or major brain damage have been reported to briefly regain full mental clarity shortly before death. This phenomenon, known as terminal lucidity, is rare and unpredictable, and there is currently no confirmed neurological explanation for it.

In 2024, bots made up a greater proportion of global internet traffic than humans for the first time. This shift was driven by both legitimate bots (like search engine crawlers) and a rapid rise in AI-powered malicious bots. (Image source: The Independent)

In high northern latitudes, such as Edmonton, Canada, the winter sun sits too low in the sky for its UVB rays to reach the ground. This means the human body cannot produce vitamin D from sunlight, no matter how bright or prolonged the exposure.

One of the primary reasons that scientists are against relocating polar bears to Antarctica is that they'd eat too many penguins.

The Westermarck effect is a psychological phenomenon where people who grow up closely together (especially in the first few years of life) tend to develop a natural sexual disinterest or aversion towards one another later on. It’s thought to be an incest-avoidance mechanism.

How salty is the ocean nearest you? This map shows the surface-level salinity average for 2023. Notably, the Mediterranean Sea is extremely salty, as is most of the North Atlantic Ocean. (Image source: Pathfinder Geospatial)

This image shows the relative sizes of many of the well-known stars. UY Scuti and Betelgeuse are positively enormous, while our humble Sun is so small that it's practically invisible. (Image source: GiovanniMartin16)

Roughly 44% of the world's adult population has never drunk alcohol. This ranges from 4.5% of Luxembourg's population up to 98.6% of Kuwait's population. Check out the interactive map: ourworldindata.org/grapher/share-…

Magnus Carlsen, arguably the greatest chess player of all time, has never lost three or more games of classical chess in a row during his adult professional career.

In a recent video, Mr Beast lined up one person from each age (1 to 100) and had them race to a finish line. This overhead camera shot captured a nice visualisation of speed by age.

The signal reaching Earth from Voyager 1 is significantly less than one trillionth of a watt. For perspective, your phone’s Wi-Fi signal is about 100 billion times stronger. We're able to receive Voyager’s signal using massive radio antennas and extremely sensitive receivers.

If every person on Earth competed with each other in a one versus one elimination competition, the eventual winner would only have to win 33 times.

Australian Prime Minister Harold Holt disappeared while swimming in rough surf on December 17, 1967. Ironically, to honour him, a swimming pool complex in suburban Melbourne was renamed to the Harold Holt Swim Centre.

The entire town of Times Beach, Missouri, was rendered uninhabitable during the 1980s after a contractor trying to control dust on its roads sprayed highly toxic dioxin-contaminated oil across the town’s gravel streets. Today, the former town has become the Route 66 State Park.

Ankole-Watusi cattle from East Africa can grow horns over 2.5 meters (more than 8 feet) from tip to tip, which is the longest of any cattle breed.

These maps show the area needed if all the world’s population was concentrated in a city with the density of various locations. (Note: the world's population is now roughly 8 billion, one billion higher than these estimates.) (Image source: Per Square Mile)

If you search Google for "sqrt(cos(x))*cos(300x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(6-x^2), -sqrt(6-x^2) from -4.5 to 4.5" it will produce the graph of a love heart.
