    One for Earl: The Romans used urine, liquid gold, to clean their teeth and keep them healthy; they not only traded in pee collected from public urinals, but those who traded in urine were taxed.

    Urine-soaked leather makes it soft, and soaking animal skins in urine made it easier for leather workers to remove hair and bits of flesh from the skin.

    Early Europeans knew about soap, though many launderers used urine for its ammonia content to remove stains from cloth. In ancient Rome, vessels for collecting urine were commonplace on streets, passers-by would relieve themselves into them and when full the vats and their contents were taken to a fullonica (a laundry), diluted with water and poured over dirty clothes; workers would stand in the tub of urine and stomp on the clothes, similar to modern washing machine’s agitator.

    Even after conventional soaps became more prevalent, urine was often used as a soaking treatment for tough stains.

    Ammonia, found in urine, is one of the ingredients in many household cleaners, which neutralises dirt and grease which are slightly acidic.

    Urine not only makes whites cleaner, but colours brighter. Urine was so important to the textile industry of 16th century England that casks of it, each estimated to hold the equivalent urine of 1000 people for an entire year, were shipped from across the country to Yorkshire, where it was mixed with alum to form an even stronger mordant than urine alone.

    Bored with cleaning, tanning, and dyeing? Then why not use your pee to make gunpowder! Gunpowder recipes call for charcoal and sulphur in small quantities, which are easy enough to find, but the main ingredient (potassium nitrate), saltpeter, was only synthesized on a large-scale in the early 20th century. Prior to that, makers of gunpowder took advantage of the nitrogen naturally found in pee to make the key ingredient for ballistic firepower.

    Different regions of the world had their own recipes for gunpowder, but the scientific principle is the same: Ammonia from stagnant pee reacts with oxygen to form nitrates. These nitrates, negatively charged nitrogen-bearing ions, then search for positively charged metal ions to bind with. Thanks to the ash, potassium ions are in abundance, and after a little filtering you have potassium nitrate.

    The adult human body has around 60,000 miles of blood vessels, enough to go round the equator twice with some to spare.

    Don't try this at home.

    There are over 70 documented cases of transplant patients experiencing the same thoughts and feelings as their original donors did in life, although the recipients knew nothing about their donors. People reported everything from craving the donor's favourite foods, to inheriting their talents. This has triggered research into the possibility that body cells can store memory.

    If you've been pooping out small nut-shaped nuggets, this is a warning sign from your body that you need a lot more water and fibre.

    From the time it was discovered (1930) to when it was declassified as a planet (2006), Pluto never made a full orbit around the sun.

    If you get bitten by most snakes the venom does not go into your blood. It travels through your lymph system, which is pumped around by muscle movement. A new discovery slows down this process, giving you more time to get to hospital.


    Scientists discover that a cream can slow the spread of a serpent’s poison....at least with Easter Brown snakes.


    For a person who has the rotten luck to get bitten by a poisonous snake, every second counts. That’s because venom can spread quickly from the site of the bite to the rest of the body, causing pain, suffering — even death. Australian scientists now have found a way to give snakebite victims more time to get help.

    A team identified a lotion that can delay the spread of some venoms. In a new study, the researchers show that when the lotion is applied near the wound shortly after a snakebite, the poison travels more slowly through the body.
    “This treatment might make all the difference between dying on the road and getting to the hospital in time,” David Warrell told Science News. Warrell, a physician and retired professor of tropical medicine at the University of Oxford in England, was not involved with the study.

    The lotion doesn’t work for all types of snake venoms. In the new study, the scientists show that it can help people who’ve been bitten by the eastern brown snake, a particularly poisonous serpent found in Australia.

    Eastern brown snakes have small heads, can grow up to seven feet long and are members of the cobra family. One bite can be deadly. “It’s particularly nasty, one of the most toxic things in the world,” Dirk van Helden told Science News. Van Helden, a physiologist at the University of Newcastle in Australia, worked on the new study.
    Some molecules of poison from snakes — like the eastern brown snake — are too large to squeeze through blood vessel walls and into the bloodstream. Instead, these bigger molecules indirectly enter the bloodstream by hitching a ride with the lymphatic system. Lymph is a clear fluid that transports white blood cells throughout the body. Lymph travels through lymphatic vessels until it drains into blood vessels. Molecules of poison can get into these lymphatic vessels and travel with the lymph, eventually winding up in the bloodstream.

    The venom-slowing lotion contains nitric oxide, which retards the spread of venom by slowing down the lymphatic system. Nitric oxide is a chemical compound made of nitrogen and oxygen. This compound is often used to treat angina, which is chest pain caused when the heart doesn’t receive enough blood. In the new experiment, the compound was used to slow down the lymph vessels, which in turn would slow the spread of the poison.

    In the laboratory, the scientists tested their concoction on 15 human volunteers (who were not required to get snakebites). Each volunteer received an injection of a harmless substance in his or her foot — this was a simulated, or faked, snakebite. The substance took 13 minutes to travel to the groin area. But that time increased to 54 minutes when the volunteers applied the lotion to the “bite site” shortly after the injection. This means that snakebite victims would have more than half an hour longer to get help.
    Unfortunately, the new lotion won’t work against all snake venoms.

    The poison of the black mamba, for example, contains small particles that can more easily slip into the bloodstream. But for people who might come in contact with the eastern brown snake, the cream could be a lifesaver.

    >>>>>>>>>>>>>>>>>>>>>>

    Just BTW, I have read somewhere that heating up a bitten limb can cause some toxins to degrade, but you'd have to do your own research on that. Useful to know though.

    While Chicago has blustery days like any other metropolis, its wind is not exceptional and it's nickname of 'Windy City' has nothing to do with weather and all to do with its people.

    19th c journalists first gave Chicago this designation when describing the city’s elite as 'full of hot air', and 'windbags' with 'inflated egos' who cared about 'nothing but profit'.

    All snowflakes have 6 sides; no two flakes are identical.

    March 1992, Syracuse, NY: More than 162 inches of snow had fallen on the city, prompting the Syracuse Common Council, privy to forecasts of no more snow, to impress the people by outlawing any more snow before Christmas Eve of that year. It started snowing again two days later.

    March 2015: The town of Capracotta in southern Italy holds the record for most snow in one day, more than 100 inches in 18 hours.

    Guinness: Tallest Snowman was 122' tall and took a month to build.

    Know your Nature

    Elevation vs altitude: Elevation is a point above sea level on land, altitude same but in the air.

    Lake vs pond: A pond is shallow enough for light to penetrate to the bottom, whereas in a lake it doesn't. Although there is no set size for either, most geographers agree that a lake is bigger than 12 acres, and smaller than that it’s a pond.

    Dusk vs twilight: Dusk happens once a day, after sunset, the darkest stage of twilight which occurs when the sun is below the horizon but still showers the landscape with indirect light. Twilight happens twice every day, before sunrise and then again after sunset.

    Weather vs Climate: Weather can be tracked daily and is specific from region to region. Climate is more wide-ranging and tracked over long periods of time. Iow, climate is a trend, while weather is a more immediate variant.

    Island vs continents: A continent is a landmass of low-density rock. An island is a landmass composed of heavier rock risen partially above sea level. Greenland is the world’s largest island, not Australia, which is technically a continent.

    Canyon vs gorge: Both are deep ravines with a stream or river cutting through the bottom, but canyons have wider, sloping walls, whereas gorges are much narrower and steeper. The Columbia River Gorge in Oregon and Washington is actually a canyon.

    Stalagmite vs stalactite: Both formed by water and minerals, a stalactite hangs 'tight' from a cave ceiling (it contains c, for ceiling) while a stalagmite has a g for 'ground'.

    Bog vs Swamp vs Marsh: All three are types of wetlands. A bog is on high ground so water drains away and is replenished by rainfall; it is covered in peat moss, making it difficult for aquatic animals to survive there. Swamps are low, flat areas where slow-moving water collects; usually muddy and home to trees and fish. A marsh borders a lake, ocean, or other large body of water, has grasses and reeds but not trees or peat, and lots of underwater life and birds.

    Hail vs sleet: Both are falling ice chunks, but hail is larger because it formed by winds pushing a small lump of ice high into the atmosphere, sometimes several times, making it grow larger and larger until it’s heavy enough to fall. Sleet isn’t prone to these massive updrafts, so it doesn’t take as much ice forming around a water droplet before gravity kicks in and makes it drop.

    Hurricane vs cyclone vs typhoon: All describe the same kind of oceanic storm with sustained winds higher than 74 mph; the difference is in their location. If it strikes North America from the Atlantic Ocean, it’s a hurricane (Hurikan, the Mayan god of evil). If it strikes China or Japan it’s called a typhoon (Greek tuphõn, “whirlwind”), though Southeast Asians call it baguios. In the Indian Ocean it’s called a cyclone (coined 1848 by English scientist Captain H. Piddington, deriving from the Greek kyklon, “to move in a circle.”) Any storm with a circular motion that isn’t strong enough to be a hurricane or typhoon, is referred to as a cyclone.

    City vs town vs village: A city is governed by a single entity (mayor and city council) enclosed in a larger entity (county, state, country). A town is smaller than a city, but like a city it can also have a mayor. But unlike a city, a town’s municipal services (utilities, transportation) are handled by the county. A village has no central governing body and can be part of a town or city. Other definitions vary by population and other features, such as cathedrals.

    Pretty amazing, if true.


    As is Menstrual synchrony (also called the McClintock effect). The menstrual cycle of two women living in close proximity will sync together.

    During Prohibition, distillers, moonshiners and smugglers wore cow shoes over snow, leaving hoofprints instead of footprints, to evade police.

    And the wind speed almost reaches 2,200kph. Nearly twice the speed of sound on Earth.
