ZANY FACTS START HERE From the mid-1600s to the early 1900s, people in Europe sometimes tossed the contents of their non-flushing toilets out of their windows. In Scotland, they called out, 'Gardy loo!' as a warning to those walking below.. Sewers sometimes develop massive fatbergs - solid chunks of fat, oil and wet wipes that people have poured down their drains In the 19th century, people known as 'toshers' would descend into the sewers of London to hunt for lost coins and valuable metals…. In Australia, pythons have been found slithering through the sewers PAINTING, WRITING & SCULPTING were once Olympic events. Nearly 3,000 years ago, during the early Olympics, athletes competed naked Human poo and pee have been flowing through Rome's Cloaca Maxima (meaning 'Greatest Sewer') for more than…

HSSS (Stop doing that!) PP-PP (I'm the queen here!) BUZZZZZ (This is how you find the flowers…) One dance that bees do is called the waggle dance.

You've probably seen oozy blobby slime in TV shows and films about aliens and mutants, but did you know that there's plenty of slime in real life as well? Most living things use slime somehow. We humans, of course, have gloopy, slimy snot and other mucus to help our bodies function, while a jellyfish's body is made of slime! Believe it or not, scientists use slime as well. They are working on ways to make slimes into adhesives to stick things together, special bandages to heal wounds, and even soft robot parts. You can be a slime scientist, too! Read on to find out how to make your very own slimes with household ingredients. THE SCIENCE OF SLIME 1 Glue is a type of substance called a polymer. Polymers are…

SPACE MISSIONS On 6th July, a group of intrepid explorers will finally be able to hang up their space suits and return home after a year-long mission for NASA. Contrary to what you might assume, however, these explorers never left the ground! NASA's CHAPEA (Crew Health and Performance Exploration Analog) missions are a key step to getting the first humans to Mars. But for now, these missions have to take place on Earth. CHAPEA missions are what are known as analog missions, which means they act as an analog, or comparable replacement, for something else. In CHAPEA's first mission, a crew of four people tested out a home base and equipment that might be used in a real mission to Mars. Analog missions give scientists important information about what might…

Sad as it is to say, the time between 1845 and 1945 seems to me to have been one of the most brutal periods in the history of humankind. During this 100 years, and for reasons that I find hard to work out, appalling violence and fighting between humans erupted in almost every part of the world. Maybe it was because the number of people in the world was increasing quickly thanks to advances in farming and technology. In 1804 the world's population passed one billion. By 1950, it had more than doubled to 2.5 billion. Having so many more people quite possibly increased the chance of clashes between countries and cultures. Or maybe living in an increasingly connected world made some people feel jealous or deprived and others more…

PHOTOS A WHALE OF A TIME In winter, orca whales such as this one are attracted to large schools of herring that migrate into the fjords of northern Norway. Orcas herd the herring into a tight ball in what is known 'carousel feeding'. WORLD NATURE PHOTOGRAPHY AWARDS/ANDY SCHMID THAT'S LOOPY! Greek BMX rider George Ntavoutian made history by completing the largest full loop with a bicycle, in a pipe that measured a stunning 7.5 metres high. That's as tall as a two-storey building!

Common frogs are the only type of frog found in the wild in Scotland. The females, which can grow up to 13 centimetres in length,…

YUCKY STUFF WHAT ON EARTH! There are more bacteria in an average-sized human poo than there are stars in the Milky Way. Why do you think humans find certain things disgusting? It's an interesting scientific question. Charles Darwin, the great 19th-century naturalist, thought that being completely grossed out by stuff served a useful evolutionary purpose. Finding the smell of rotten eggs or mouldy fruit physically revolting, for example, warned early humans not to eat them and so helped them to avoid getting sick. Seen in this way, humans' instinctive sense of disgust is our immune system's first line of defence. It advises us not to touch or eat things that might otherwise endanger our health. But why, you might then ask, are humans, and children especially, also strangely drawn to…
