After the USSR made cosmic history by sending the world\u2019s first artificial satellite, Sputnik, to space in 1957, the U.S. hoped to follow up with an unprecedented display of power. \u201cSpecific positive effects would accrue to the nation first performing such a feat,\u201d according to&nbsp;a 1959 report&nbsp;that was declassified in 2000. These bizarre plans might have remained under wraps to this day if not for Carl Sagan, the celebrated astronomer. At the time a Ph.D. student at the University of Chicago, Sagan was recruited by renowned Dutch astronomer Gerard Kuiper to help spearhead what became known as Project A119.

Inside the spider metropolis \u2014 population 111,000 \u2014 were two species that had not been known to live together harmoniously, mainly because one species tends to eat the other.The team of scientists discovered that 69,000 Tegenaria domestica, known as the barn funnel weaver, were living with about 42,000 Prinerigone vagans, which inhabit wet places. Usually the barn funnel weavers prey on P. vagans, which are smaller. The cave itself was hollowed out by sulfuric acid formed from the oxidation of hydrogen sulfide in the groundwater.

Before it began to be treated as a single word, it was rendered as \u201cMag Pie\u201d, a sort of fanciful full name for the creature. The same type of thing happened to the daw, who was eventually christened with the proper name of Jack Daw. While the magpie and jackdaw have kept their human nicknames into the present day, Philip Sparrow hasn\u2019t been so lucky. In fact, almost every bird used to have a nickname of this sort that has long since fallen out of common use. In the UK, you might still hear the names \u201cJenny Wren\u201d, \u201cTom Tit\u201d, and \u201cJack Snipe\u201d, but these are just a drop in the bucket of what used to be. 500 years ago, Mag was a common generic name for a chattering, gossipy woman, Robin was a charming nickname for little boys, and Jack was associated with mischievous men.

More than six centuries ago, these pockmarks might have served as a tax spreadsheet of sorts for the Inca Empire, according to new findings&nbsp;that were recently published&nbsp;in the journal&nbsp;<em>Antiquity<\/em>. These mysterious mountain dots were captured in aerial photographs by&nbsp;<em>National Geographic<\/em>&nbsp;explorer Robert Shippee, which were published in 1933. Since then, they have captivated the public and researchers, who have offered up wide-ranging explanations behind their origins: capturing fog, collecting water, mining, gardening, or even&nbsp;aliens, among other theories.

Wool was often treated with urine during processing \u2013 until the invention of more modern ammonia processing \u2013 to clean and soften the fabric. For washing, aged urine was used. It was left overnight in vats at a ratio of one part urine to two parts water. The mixture was then heated to approximately 50 degrees Celsius, and the wool was washed in it. Those who worked at the woolen mill were asked to bring along a full bottle of urine to work every morning. This gave the Tilburgers their nickname of&nbsp;<em>Kruikezeikers or &#8220;jug pissers.&#8221; <\/em>There is a famous statue in town of a man peeing into a jug, and one of the town&#8217;s traffic lights even includes a silhouette of someone doing so for the &#8220;don&#8217;t walk&#8221; signal, and a man carrying a jug for the &#8220;walk&#8221; signal.
