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.
Ducklings in Disguise
You know the story of the Ugly Duckling of course, who didn’t look like his family but grew into a beautiful swan? Well, this is a true story of three little chicks who are going to grow into beautiful ducks, as told by Susannah Leigh.
It all started when my friend Nic’s very favourite chicken, Rosie became broody. Rosie laid some eggs and sat on them very carefully for a very long time. But the eggs didn’t hatch and Nic realised that they were probably never going to. Sometimes they just don’t.
Poor Rosie – all that patient waiting for nothing.
My Multilingual Life – Written By You
‘Do you speak English?’
For British and American girls who travel to a different country, that question is often the first sentence we learn.
‘Sprechen Sie Englisch’
‘Parlez-vous Anglais’
‘habla usted Inglés’
‘Вы говорите по-английски’
‘您说英语吗’
What is it like for the estimated two thirds of the world’s population who speak at least two languages? The people who we refer to as ‘bilingual’, if they speak two languages, and sometimes as ‘multilingual’, if they speak more than two languages.
The researcher and writer David Crystal estimates that of the approximately 570 million people in the world who speak English, over 41% are bilingual in English and some other language.
Today’s contributor knows all about speaking more than one language.
Women in Politics: Be The Change You Want To See
Recently the online parenting website Mumsnet ran a survey which found that people in politics are seen to be ‘white, middle-class and male’. We think that ANYONE can become an MP, so we decided to chat to some politicians about diversity in politics.
First up, we wanted to know what it is really like for women in politics. We asked Tina to chat with Heidi Alexander, Labour Minister of Parliament for Lewisham-East in London.
A Trip to Mars!
Imagine being able to catch a flight to Mars as easily as we travel to another country – that was the idea behind the Trip To Mars session I attended at the Cheltenham Science Festival. It was conducted by Dr Suze Kundu and Dr Simon Foster and presented as a pre-flight safety briefing, with both of them dressed as pilots! There were a lot of humorous moments and sci-fi references but also some great science.
Suze and Simon suggested that in the future, flights to Mars could be far quicker than they are now, and explored how some of the bigger problems could be overcome. For example, the Sun’s magnetic field deflects a significant proportion of the cosmic radiation that could be harmful to humans on Earth; as spaceships travel further away from the Earth and Sun they will have less protection because the magnetic field weakens. To combat this it’s possible that spaceships will contain or be covered with large and powerful magnets, to produce the same deflective effect. This would have the added advantage of also deflecting radiation from solar flares.
Spaceships journeying to Mars would travel at such speed that even tiny fragments of rock and dust could be damaging to the hull. To combat this, and also the heat generated when the spaceship passes through an atmosphere, Suze and Simon discussed the possibility of spaceships being coated in aerogel. This amazing material is a solid formed from silicone dioxide but is 98% air; this means that it is extremely light but also strong. Its melting point is 1,200°C (equivalent to asbestos) and it is a wonderful insulator. Because it consists of large pockets of air between thin layers of silicone dioxide, any dust or rock fragments that hit it would be slowed and stopped before they could penetrate the aerogel completely.
Suze and Simon also discussed the possibilities and problems with cryostasis. Theoretically this is when a person’s body is cooled to temperatures so low that they enter hibernation, ideal for long journeys through space. Unfortunately our technology isn’t advanced enough to do this at the moment; any attempt would result in the cells rupturing and the person dying. But in the future it will be possible, perhaps after the person’s DNA has been altered slightly so that they can produce antifreeze proteins like some species of wasps and turtles.
