Today it's a museum and features toilet-themed art on the grounds, including a golden pile of poo There's a museum in Texas that features more than 1,400 artworks - all created on toilet seats Some museums keep collections of flesh-eating beetles to help clean skeletons for display About 15,000 to 18,000 new animal and plant species are discovered every year. Sometimes they're found in the wild but at other times they're in stranger places.

DO ME A FAVOUR Five examples of animal mutualism Mutualism is a term used to describe a partnership between two organisms in which both species benefit. 1 Clownfish and sea anemones Clownfish are often found swimming among the tentacles of sea anemones, which sting nearly all other fish. Thanks to a special mucus (slimy coating) on their skin, the clownfish aren’t harmed. In return for a safe place to live, the clownfish chase away the anemone’s main predator, which is the. butterflyfish. 2 Remoras and sharks Remoras are small fish that attach themselves to sharks and other large marine animals. The remoras help the sharks by keeping their skin free of parasites. They are even allowed to swim around the sharks’ teeth to remove bits of food that might otherwise become breeding…

Soap Bubble One example of a perfect sphere here on Earth is a soap bubble. When you blow soap bubbles, they often start off with an irregular shape. But once they are floating in the air, they usually pull themselves into perfect spheres. The reason for this is a force called surface tension, which is present between the water molecules in the soap. The water molecules tug on each other equally in all directions. This causes them to pull the bubble into a perfect sphere. Kepler 11145123 Rarely do planets and stars form perfect spheres, but astronomers have found one star that comes really close. It’s a star about 5,000 light-years from Earth and is called Kepler 11145123. It is the most spherical object in space that astronomers have discovered…

DON'T LOOK DOWN! Do you have a head for heights? Erika Sedlacek clearly does!

Why dolphins are having to squeak up Dolphins use high-pitched whistles to communicate and to hunt using echolocation, like bats do. So it’s worrying news that human activity, such as shipping and drilling, is raising underwater noise levels. According to new research by the University of Bristol, dolphins are having to compensate for the rising noise pollution by making their calls longer and louder so that they can still be heard by other dolphins. This tiny robot can turn to liquid and then re-form! Scientists have invented something that looks and sounds as if it comes from a science-fiction movie: a tiny shape-shifting robot that can melt into a liquid and then reform to become solid again. The robot, which is just 1 mm tall and shaped like a LEGO…

We often like to think that humans are the dominant species here on planet Earth. But, in many ways, insects are the ultimate success stories of the animal kingdom. Did you know, for example, that around three quarters of all known animal species are insects? They include butterflies, beetles, ants, flies, bees, wasps and grasshoppers, along with many other kinds of creepy-crawly. (Animals that are not insects, though which are sometimes mistaken for them, include spiders, centipedes, millipedes, scorpions, crabs, snails, earthworms and woodlice.) Insects are able to survive in all kinds of natural habitats, both on land and in water, and have been living on Earth for hundreds of millions of years. THREE QUARTERS OF ANIMAL SPECIES ARE INSECTS Insects make up around three quarters of all known animal…

As a young man, Prince Alexander was a good student and great with horses. At least he was great with his own horse, Bucephalus. His father, Phillip II, was king of the northern Greek city-state of Macedon and was busily creating an empire by defeating other states. So of course he could afford the best education for his son. When Alexander was 13, his dad hired a great philosopher to run a small school for Alexander and his friends. That teacher was named Aristotle, and he ended up as probably the most famous Greek philosopher of all time. He thought and wrote about everything from nature to space and from city politics and public speaking to poetry, music, memory and logic. Aristotle’s thinking led him to a very important idea.…
