Science News – Womb Transplants
It has recently been announced that one of the first women to receive a womb transplant has given birth to a healthy baby boy. But what are womb transplants and how significant is this development?
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.
Adventure in Uganda
On my second day in Uganda, we went white water rafting on the Nile, near a town called Jinja. The rapids are just 
down river from Lake Victoria, which is where the Nile starts.
The rapids are caused by the force of the water as it crashes over rocks and around islands in the river. There used to be more rapids there, and the famous Bujugali Falls. However, a couple of years ago a dam was built across the river, which has made part of it more like a lake and has increased the water levels, wiping out lots of the rapids, including Bujugali. However, below the dam, the rapids are still just as scary! The rapids are a favourite for rafters and kayakers all over the world.

SCIENCE NEWS – Discovery of An Underground Ocean
Earth’s Underground Ocean
In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.
An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.
