A History of Fandoms
A lot of adults are very critical of the fans of 1D or Zoella, thinking they are silly for getting so excited, and for screaming and shouting. But did you know that fandoms have existed for a very long time? They’ve not always been called fandoms; that is a fairly recent development, but they are nothing new.
Life as a Child with a Chronic Condition
A chronic condition means a type of illness or disability which will be a part of your life for the rest of your life, and will mean medication or other type of medical treatment such as physiotherapy (exercises designed to treat and strengthen your body) and regular visits to the doctor or hospital or both.
If you’ve been diagnosed with a chronic condition, it can be scary and upsetting. You may not know what was happening, and you will probably have lots of questions. We spoke to Tina, who grew up with a chronic condition on what’s learned over the years, and asked her advice on living well with a health condition.
A Day In the Life Of…a Biologist
Ever wondered what being a biologist might be like? No two scientists work days are the same but I’m going to take you through my typical day to give you an idea
7 AM: I get up and eat breakfast (toast and a cup of tea) before travelling to work.
8 AM: I arrive at work (this is early for scientists, most of my workmates arrive at about 9 AM but I like to get up early!) After checking my email the first job of the day is to turn on the microscope above.
The plant root surface is covered in root hairs. This is what they look like under a microscope.To get an idea of the cells, les than 1mm of plant root can be seen in this image
It is similar to microscopes you may have used at school but with a few added features including a special camera. I am fascinated by plants and in my research I am trying to find out more about how some plants (including peas and beans) can form a friendly relationship (known as symbiosis) with soil bacteria, which provide nutrients that the plants need to grow. I use the microscope and camera to study living cells in plant seedling roots (where the symbiosis is set up).
10:30 AM: Tea break and seminar. I have a tea break with some of my workmates and then go to a seminar where other scientists talk about their research and we discuss it afterwards. Seminars are a great way to find out what experiments other scientists are doing, and to get ideas for new experiments to try.
12:30 PM: I have lunch with my friends.
1:15 PM: More experiments. For some of my experiments I have to grow plants in greenhouses. Today I visit to check on my plants and collect some to take measurements. This involves digging up the plants and cleaning them to look at their roots. This is fun, but messy!
3:30 PM: Afternoon tea break.
3:45 PM: Data analysis. I spend the last part of the afternoon drawing graphs of the data I have collected today and thinking about what it shows (does it answer the research question? Do I need to do further experiments?). I also spend some time reading research articles to find out about experiments other scientists have been doing.
5:30 PM: Hometime! Once I am home I have dinner and then relax.
One of the things I love about being a scientist is the feeling of discovering the “unknown”. The experiments I carry out reveal little details that when combined with other scientist’s data can help us build up a picture of how the plant-bacteria symbiosis is set up so that pea and bean plants can get the nutrients they need to grow. We hope that this knowledge might be able to help improve farming in the future.

Sarah Shailes is a plant scientist working at the John Innes Centre, Norwich, UK. She studies how some plants can form a friendly relationship (symbiosis) with soil bacteria, which help the plants gain nutrients they need to grow. When she isn’t in the laboratory she enjoys knitting and hiking, and helps run a local Brownie Guide unit.
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.
What is the Mexican Day of the Dead (Día de los Muertos)?
On 1st and 2nd of November, Mexico celebrates its Day of the Dead (Día de los Muertos). This is a festival that begins on 28th October and ends on a public holiday on 2nd November. During this time, Mexicans believe that the deceased have permission from God to visit friends and relatives on earth, and once again enjoy the pleasures of life. It isn’t seen as a time of sadness and mourning but as a celebration of life.
Where Does the Tradition Come From?
The Aztecs believed that death was just a part of the circle of life and offered gifts to the goddess Mictecacihuatl (“Lady of the Dead”) for deceased children and adults. This tradition was incorporated into the Catholic celebration of All Saint’s Day and All Soul’s Day when the Spanish conquered the country. You might know All Saint’s Day by its other name – Halloween!
