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.
What is the Orionid Meteor Shower?
This October Earth will be passing through the tail of Halley’s comet, which will mean a shower of meteors flashing across the night sky. Our science editor Sam Gouldson explains.
What is Halley’s Comet?
A comet is a lump of rocky particles, ice and dust all bound together like a dirty snowball. When the comet nears a star, its surface transforms from a solid to a gas. The star’s light shines through these gases and makes them visible to observers as a fuzzy cloud around the comet’s centre, and a tail streaming out behind.
Winter Wonderings – Why Does Frost Make Patterns?
The third #winterwonderings post from our Science Correspondent, Samantha, we take a look at why frost makes patterns. Many countries have a mythical figure like Jack Frost, who draws in the ice and frost in winter, but what really causes these gorgeous natural designs.
What is Biotechnology?
Perhaps you have heard of the term biotechnology and wondered what it is. You may think you know already – after all, the parts that make up the word are very familiar: bio + technology. You have seen the first part of the word in biology, antibiotics, all sorts of words. It comes from Greek bios, which means ‘life’.
As for technology, it is not just about computers and smartphones. Technology is the practical use of knowledge to create useful things and solve problems. You might like to think of it as tech-knowledge-y. So, taking it one step further, biotechnology is about using biology in technology.
We talked to Alessandra Iscaro, a biotechnology researcher at the University of Florence, Italy, and she explained to us what it is all about.
