BIZARRE BELIEFS The fireproof salamander Salamanders are brightly coloured amphibians that look a bit like a lizard crossed with a frog. They are nocturnal animals which are found in many parts of the world and are especially common in North America. The name salamander comes from an old Persian word meaning ‘fire within’ and is connected to a strange and ancient belief: that salamanders are fireproof, and able to both start a fire and put one out. In fact, during the 1st century CE, a Roman writer and naturalist named Pliny the Elder is said to have thrown a salamander into a fire to test if the stories of salamanders’ magical, fireresistant powers were true. Unfortunately they aren’t, and the poor salamander did not survive the experiment. Farts in a…

Why do cats love hiding in boxes? Do you have a cat? If you do, have you noticed whether it likes to sit inside boxes? Most cats do, and it’s not just domestic cats: big cats such as tigers do it too. Scientists think this could be because the gentle pressure the cardboard box exerts on the cat’s sides feels similar to the feeling of cuddling up to other kittens when the cat was young. Alternatively, it could be because cats are ‘ambush predators’ that like to hide and then sneak up on things unawares. Experts in cat behaviour at the Messerli Research Institute in Vienna, Austria are continuing to investigate the phenomenon! The AI computer program that reads people's minds Artificial Intelligence, or AI, is a branch of computer…

Very few reptiles survived the terrible Permian Mass Extinction, which occurred 266 million to 251 million years ago and may have been caused by massive volcanic eruptions. It led to the extinction of about 95 per cent of marine species and about 70 per cent of land species. Thankfully, one of the reptiles that did survive was Lystrosaurus, which was an important species for humans. Lystrosaurus is a link between reptiles and mammals. If it hadn’t survived, some experts think mammals may never have evolved at all. Humans are mammals. So we must be thankful that this possible distant ancestor of ours made it, even if it did look like a cross between a lizard and a pig. Then, out of disaster came a completely new generation of reptiles. These…

DO IT YOURSELF When you arrange small pieces of stone, tile, glass or other material to form a picture or pattern, it is called a mosaic. Mosaics are often used to decorate buildings, but they can also be thought of as beautiful works of art in themselves. People from different parts of the world have been making mosaics for centuries. You’ve probably seen examples of ancient Greek and Roman mosaics. But did you know that the ancient Mesopotamians, Islamic peoples of the Middle East, Pueblo Indians of North America and Incas of South America all created wonderful mosaics too? One of the most famous Roman mosaics was found in Pompeii, the city destroyed by the eruption of Mount Vesuvius in 79 CE. It shows the ancient Greek king Alexander the…
