James: Why do bookshops smell so good?

I am sure we have all come across an old book at one time or another opened it merely to stick our noses in. I for one do for it gives me a sense of that I am learning from the past. But little did I know, until very recently, that the compound that causes this blissful olfaction is one of the most common forms of organic polymer with only cellulose more abundant.

What I am talking about is Lignin; a complex chemical compound which acts as a main part of the secondary cell wall, in the plant cell diagram by Caroline Dahl you can see the secondary wall labelled.

So how and why old books, well the lignin is relatively aromatic as it is the key is when it breaks down over time one of the products being very closely related to vanillin. Which is the main extract of the vanilla bean. So that sweet scent emanating from the very pages of our favourite old books is due to the active decomposition of the ancient molecule that was once constructed by a tree in order to keep it's cell strong and protected from pathogens. It gives quite a view to the world around to think that so much must have come before to get us to where we are now. And with that poignant thought I leave you.

Imagination is More Important Than Knowledge: Science-inspired fiction and poetry open mic night!

A wonderful time was had by all last night at the Grant Bradley gallery at the University's Changing Perspectives science-inspired fiction and poetry open mic night. I was host for the evening and, to kick the whole thing off, read my stories Experimentation (from the lab coat I'd written the story on for the Changing Perspectives exhibition) and Healing Wounds.

I was then more than delighted to hand the mic over to 14 readers, who read short stories, poems and excerpts from longer works, all in some way taking science as their starting off point. We moved from oxo cubes to cockroaches, aspirin to drowned cities, speculative Wessex fiction to gifted children, Brian Cox (!) to Pingu the penguin.

I have to say that I don't know about anyone else but I found it all extremely inspiring! We had such a range of readings, across many "genres" (although I hate labels), different styles and tones and subject matter. I loved it all: thank you to Jo, Cath, Stewart, Mary, Mazzy, James, Caleb, Amy, Franca, Tom, Colin, Gavin, Andy and Katrina!

Becky Jones - PhD student from the biochem lab I've been embedded in and organizer of the Art of Science competition - and I had the impossible task of picking just four people to give these wonderful books (above) to, so congrats to Jo, Caleb, Amy and Franca - but really congratulations to everyone, it was a wonderful celebration of using science as inspiration, whether you have any scientific background or not, none is necessary. As Einstein said: Imagination is more important than knowledge. I think he would have enjoyed last night.

Win beautiful books - come and read your science-inspired fiction and poetry!

On April 19th at 6pm at the fabulous Grant Bradley Gallery in Bristol, I am hosting an open mic night for fiction and poetry in any way inspired by science. This is part of the amazing Changing Perspectives month of exhibitions and activities bringing together art and science.. This event is completely FREE to attend (but booking is required, click here) and you can win one of several great prizes, including these books:

Radioactive: Marie and Pierre Curie, A Tale of Love and Fallout by Lauren Redniss

Periodic Tales: The Curious Lives of the Elements by Hugh Aldersey-Williams

When It Changed: Science Into Fiction, an Anthology edited by Geoff Ryman

The White Road and Other Stories by Tania Hershman (yes, that's me)

I will be judging, and the theme of the evening can really be interpreted however you like - any genre, any style, as long as something scientific in some way was the inspiration. (I wrote more on my thoughts about this on the Wellcome Collection blog)

To prepare for the open mic, I will be jointly running a science-inspired fiction workshop on Wed 13th April, which once again is completely FREE, at the Grant Bradley Gallery, 2-4.30pm - booking is required, see here. Come and write!
