Istanbul – Through the Eyes of 13 Year Old Maya
Maya is 13 years old, and lives with her family in Bangalore, India. She wants to tell us a bit about Istanbul, and show us the parts of the city that she loves.

POO-EE! Roman Toilet Seat Found Near Hadrian’s Wall
How would you like to root around in a 2000 year-old toilet?! The Romans created aqueducts, newspapers, and bound books… but did you know they helped create the toilets we have today?
Archaeologists at a Roman excavation site in Northumberland have recently uncovered a wooden toilet seat…that is 2000 years old! While it looks a bit more basic than the toilet seats we have today, it shows that they were very concerned with cleanliness.
The Roman wooden toilet seat. Not looking bad to say it’s 2000 years old! (Source.)
Health Matters … Threadworm
In the second of a series of articles on health, pharmacist and writer Asha Fowells looks at threadworms. This may make you go ‘euuuuuw’, but it is an important thing to know about, because while threadworms are icky, they are reasonably easy to treat.
The term “parasitic infection” may make you think of intrepid explorers in rainforests and jungles, but there is one parasite that lurks much closer to home: threadworm.
Things that make you go poo….
After talking about bones in my last article, I thought I’d go on to talk about poo, or at least how it’s made.
I like eating. I think a lot of people do. Biscuits are a particular favourite…chocolate Bourbons especially. But how do we get from biscuit, or apple, or stick of celery to the brown stuff we call poo.
Well, it’s thanks to the digestive system, which starts at the mouth, and runs all the way to our bottoms. So let me take you on a guided tour.
Winter Wonderings – Are Snowflakes Really All Different?
It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.
However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.
The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!
