Sir Paul Nurse and Poetry

Photo: Royal Society
There were two great events held here in Bristol last night, one at the University and one at the Bristol Old Vic, and I was hoping against hope that I would find a connection between them to make this blog post flow! And... what do you know? I did. The first was Sir Paul Nurse, president of the Royal Society, Nobel Prize winner, geneticist, president of Rockefeller University New York... all-round very very interesting scientist and excellent talker-about-science! He was giving the Sir Anthony Epstein lecture at the Wills Tower, in the largest, cathedral-like space, which was packed to the rafters... His topic was "Great Ideas in Biology" and he was quick to point out that these weren't THE great ideas in biology but his pick of great ideas... although he felt that most people would agree on 4 out of the 5.

So, what were his great ideas? Well: The Cell, The Gene, Evolution by Natural Selection, Life as Chemistry (and Physics) and the fifth, possibly contentious one, Biology as an Organized System, by which he meant looking at the biological networks and how they are structured, looking at the flow of "information", at the system as an information carrier.

It was all fascinating stuff, some of which I already knew a bit of, but always good to be reminded what a chromosome is, for example... with some great slides and historical perspective! I was then heading to a poetry event, so, I hear you ask, how are the two connected?? Well, it was at Great Idea Number 3, which you would assume centred around one Charles Darwin. But no, in fact Sir Paul wanted to focus on Charles' grandad, Erasmus, who was the first to talk about evolution (Charles later supplied the vast quantities of data to prove it). Not only that, apparently Erasmus - who was a colourful figure, so large that he cut an oval out of his dining table so he might sit rather nearer to his supper, and fathered 14 children - was a poet, at one time "one of the best known poets in England"! And not only that, he wrote much of his scientific reports in blank verse! (See Jenny Uglow on Erasmus Darwin's poetry in The Guardian). The Poetry Foundation gives us his poem, The Botanic Garden, and here is an excerpt:
 “You taught mysterious Bacon to explore
Metallic veins, and part the dross from ore;
With sylvan coal in whirling mills combine
The crystal’d nitre, and the sulphurous mine;
Through wiry nets the black diffusion strain,
And close an airy ocean in a grain.—
Pent in dark chambers of cylindric brass,
Slumbers in grim repose the sooty mass;
Lit by the brilliant spark, from grain to grain
Runs the quick fire along the kindling train;
On the pain’d ear-drum bursts the sudden crash
Starts the red-flame, and death pursues the flash.—
Fear’s feeble hand directs the fiery darts,
And strength and courage yield to chemic arts;
Guilt with pale brow the mimic thunder owns,
And tyrants tremble on their blood-stain’d thrones.

Stirring stuff! Now the poets I went to see after this lecture, Luke Kennard and Tom Philips,  did not deal directly with biology but I feel that Erasmus D would have enjoyed the evening, which moved from a searing critique/love poem about Portishead to a tale of the Murderer being taken for a haircut. I was immensely impressed by the whole event, organised monthly by Word of Mouth -  highly recommended if you are in the vicinity!

So, an evening of poetry, biology and biological poetry, what more could I have wanted?

Learn more about public engagement opportunities

(Posted on behalf of Ed Drewitt, School of Earth Sciences)

Hi everyone,

With many of the departments in the University involved with public engagement, there will be various opportunities for you as staff or postgrads to get more involved both with these and other volunteer experiences. Being involved with the outreach work is a great chance for you to increase your confidence with delivering to various different audiences (from 5 year olds to 14 year olds) and to help provide you with the experience to confidently include public engagement activities in your future research bids.

 On Tuesday 1st November we welcome Nicholas Garrick (Director of Lighting Up Learning) and Claire Dimond (STEM- see below) who will give 4 workshops throughout the day (it'll be the same workshop repeated) which will give additional advice and skills relating to delivering high quality and effective workshops in schools. These will be held in the Wills Memorial Building.

 It is a chance to learn about where schools are at, changes in the school system since we were at school (even if it was a few years ago) and tips on good practice when doing activities and workshops. Timings and rooms are as follows:
School of Earth Sciences, Wills Memorial Building  
9am - 10am G25
12pm - 1pm G27
1.15pm - 2.15pm OCC (Old Council Chamber) -on the corridor above G25 and opposite the student common room
 2.30pm - 3.30pm OCC (Old Council Chamber) -on the corridor above G25 and opposite the student common room 

To help deliver workshops we also encourage you to sign up as a STEM (Science, Technology, Engineering and Maths) Ambassador: We recommend you do this before the 1st November so you can show document to Claire Dimond on the day. As part of your commitment with being involved with schools and families, we ask that you join up as a STEM Ambassador. STEM Ambassadors are people from industry and universities who visit schools to give talks or workshops relating to STEM subjects. Alongside the workshops we offer you'll get regular newsletters about other things you can do in schools locally.

You'll get CRB (Criminal Records Bureau) checked for free and be covered under insurance for any school visits. For more information and to sign up as a STEM Ambassador click here.

Looking forward to see you next week.
 Best wishes
 Ed

The Perfect Egg in Nature


I'm delighted to have a short story in the Futures section of the venerable science magazine Nature this week - it's just gone online today and is in the print issue which I believe comes out tomorrow. It's called The Perfect Egg,  and it was sort of my first real attempt to write science fiction. Yes, some of the short stories in my book might be kind of SF-ish, but that wasn't my aim when I was writing them. Nature Futures is "a forum for the best new science-fiction writing, exploring some of the themes that might challenge us as the future unfold" and I never expected to get my first submission to them accepted. This story seems a bit different from the other Futures stories I have read, so I am delighted to have made it - and rather thrilled that in their email to me they addressed me as "Dr Hershman"! (Don't worry, I put them straight on that...) Anyway, comments can be left on the online version, should you feel moved to! (No pressure). Read it here.

Tania's Tales from the Lab: Part 3

I'm in the lab again today, I won't do a minute-by-minute live blog but I thought I'd write down some of my thoughts. After two months or so embedding in this lab, I feel now I have some kind of understanding of how difficult it is to ever assert that you know anything. Looking into science from the outside it seems that scientists run experiments to see if Z happens when Y is put with X, get results and hey presto, we have a new FACT. We think scientists have cutting-edge equipment on their lab benches, ultra-fast computers, powerful electron microscopes, so that they can see exactly what's what.
I mean, this is how it is on CSI, right?

Well, no.

The first thing I now have more of a grasp of is that you need to check, if not every step then every few steps and they might be many many steps in your experiment! - that you even have the right stuff in your test tubes! As one of the postdocs said to me last week, "It all looks like cloudy liquid" so how do you know what's in the cloudy liquid?

If you are interested in molecular biology, well, you run a gel... This, says Wikipedia, is:
a technique used for the separation of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or protein molecules using an electric field applied to a gel matrix

and this is the equipment:


Guess when this method was invented. Well, the first reports were some time in the 1930s. At least 80 years ago. And this is still, from what I understand, one of the best and most useful methods to figure out what's in your cloudy liquid. You have a wedge of gel in this bath contraption, you have a set of little wells into which you put your different samples - tiny drops of your cloudy liquid as well as control samples just to compare - and then you run an electric current which pushes the molecules of your liquid through the gel from top to bottom. Basically, the bigger molecules get stuck moving through the gel and the smaller molecules can move through a bit faster so get further. Like a race between very fat tortoises that get stuck getting down the corridor and skinnier tortoises - and all sizes in between!

After about 25 minutes or so, your gel is "done", your tortoises have moved as far as they're going to move. You take the gel out, stick it in another machine that shines UV light through the gel and you can take a photograph which looks something like this:


Clear now? Yup... I don't really know what it means either. The bands of light are molecules and some haven't moved far from the top, and some, like the guy in the bottom left corner, got pretty far...To the trained eye, this tells you everything.

Jut for fun - and a little education! - here is a 1930s concept brought into the 21st century with this cool animation about how to run a gel that I found on YouTube (with rock soundtrack):


When your gel tells you that there's stuff in your cloudy liquid that you didn't expect to be there, or something doesn't show up that's "supposed" to be there, then what do you do? Run the gel again - which involves preparing more samples etc.., can take a day or more. And if it happens again? Check all your equipment in case something snuck in. Check and re-check. And if still not...then you might need a complete rethink.

So, to sum up, to actually "see" in science isn't as simple as looking at a sample or sticking it in your fancy million-pound desktop machine. It often means using a technique developed in the 1930s and which can take days to prepare for. Anyone want to share gel stories? And talking of stories... more about the idea of "story" in science next time. Back to the lab!

Calling all potential bloggers!

I'm in the lab again today, but won't be blogging live, that was a little stressful! I might do it once a month or so. But here's the thing: this blog is not supposed to be just me me me. Ideally, there'd be a number of Bristol Uni science folk blogging here, so if you'd like to join in, do drop me an email at tania(dot)hershman(at)bris.ac.uk (replacing the (dot) and (at) with . and @). You don't need to know anything about blogs or blogging, I'm happy to help you get started. It's great fun - I very often find out what I'm thinking about something as I'm writing a blog post on my personal blog, TaniaWrites, so it can be useful! Try it, you might just like it...
