CT images of underground soil structures, created by worms and imaged by the 糖心原创, are being revealed in a half-term display at the . A video of the 3D images can be .
The pictures show in detail the intricate tunnel structures created by earthworms. They are part of a research project involving experts from the in the School of Biosciences and led by Dr Jackie Stroud (), a NERC Soil Security Fellow based at to look at the impact of different farming techniques on earthworms.
Worms are ‘soil ecosystem engineers’ working to keep soils healthy. They burrow deep into the ground, making air pockets in the soil, which allow the soil to act like a sponge – soaking up the rain to provide water for growing plants. Without those air pockets, rain runs straight off the surface taking some soil with it which can cause flooding.
Using state-of-the-art equipment, Dr Craig Sturrock, an expert in X-ray Computed Tomography, has created a video clip showing an X-ray CT scan of a pot planted with NASA wheat and containing the anecic earthworm Lumbricus terrestris that has been burrowing in the soil for a month.
Dr Sturrock said: “Understanding how farming techniques affect living organisms in the soil like worms can help us to protect our soils, and help to limit erosion and flooding. We’re delighted to be sharing the images with the public at the Science Museum, as they provide a fascinating insight into the world beneath our feet!”
You can come and see the soil, the scans and explore earthworm burrows at the Science Museum exhibition ‘’ #wormscience exhibit, from 29 – 31st May 2017 from 11am-1pm and 2pm-4pm.
