tMoL: Big Cell, Little Cell

I’m writing this as a homage to one of my closest friends on the blogosphere. The every wonderful LabRat has finally ended her fraught relationship with scientific research and is throwing herself wholeheartedly into science writing. Whilst I am hugely envious, I wish her all the best and hope she will remember me when she is rich and famous. Look out for her in future publications.

By way of background; Lab Rat has always had a fixation with the simpler things in life, by which I mean bacteria.

False colour E. coli, bacterial/prokaryotic cells.

All living organisms are made up of cells individual living units which are relatively self-supporting and capable of total self-replication, although this is complicated by the intricate interactions between different cells in larger organisms. Whilst larger creatures, like humans are made up of billions of cells, the vast majority of life on Earth exists as single celled microorganisms that cannot be observed with the naked eye.

Cells fall into two main groups, larger and more complex organisms, plants, animals and fungi are called eukaryotes (that’s us humans too) and have much more intricate cellular structures. The earliest forms of life, with the simplest cells are called prokaryotes, which include bacteria.

Resurrection: Halloween, spooky proteins and the return of ClearSci

It’s Halloween night and a dark shape is moving towards you through the ether of the information superhighway. Surrounded by the blackness you feel something closing in, disturbing the thick layers of accumulated dust. Just as you’re about to start screaming in terror… IT’S ME!!! Lights on, and by gosh it’s a mess in here, I don’t remember putting all of these spiders up for Halloween. Eww! Eww, eww, they’re real. I’m really going to need to spend some time cleaning all of this up…I’ll deal with that later.

Halloween revival.

So, if you’re here that means you’ve been on the look-out for more of my slightly eclectic and sporadic brand of science writing and I will try not to disappoint this time. Just so we’re all caught up, no I’m not dead and neither is this blog, it just went into reverse-hibernation over the summer (that’s called aestivation, if you’re interested). Also, neither of us has been temporarily reanimated for Halloween, this will hopefully be working its way back into my normal routine.

Summer was great! Although crazy, so I didn’t have much writing time (poor excuse I know). I joined the college graduate committee so I’ve spent a lot of time planning and organising events for our new freshers and negotiating college politics. I also finished the third rotation for my first year (currently in editing for the Wellcome Trust), selected my PhD project and wrote the full project proposal (I’m back with the second lab, playing with fission yeast genes). All of that earned me an MPhil which I will be collecting sometime in the new year.

A Right Royal Easter Spring Conference

Hi everyone! Sorry for the neglect, I'm working on several things at the moment so this place has been a bit neglected (hides the cracks in the paintwork). Have no fear that I do have several things chasing each other round my brain and one or the other of them may actually make it into print shortly.

Firstly, the launch of the Easter issue of BlueSci is expected on Thursday, so it's been crazy getting that printed and making sure that the online version will be ready to go too. Thankfully I think I'm on top of that now, but that was quite a few evenings eaten.

Also, and probably most excitingly, I went to my first real, proper, grown-up conference over most of last week so what with the long hours I was a bit short on news hunting/writing time. I did however squeeze in time to write several daily pieces for ConferenceCast, which will be appearing over the next few days. It was really cool, focusing on Cell & Developmental biology so we had loads of great speakers (and the occasional dull one, but not everyone's perfect). The prize winners were all awesome and really interesting, especially the Beddington medal winning PhD student who used music to illustrate how well cells moved together during migration.

Now I finally get some time in my third and final lab of the year, 2 weeks after we offcially started, so it's going to be pretty intensive to try and get some results in just 7 weeks. Also I'm putting together a poster about the importance of science communication for a one day conference later in the week.

 I also had to watch the new series of Doctor Who, of course, which is fantastic, although like everyone else I have NO clue what's going on.

So if you've been missing my senseless ramblings you can pop over to ConferenceCast and see exactly what I've been up to and I promise to get my next proper piece up ASAP and to stop writing all about myself.

Lab 1: Only the Nose Glows (The reality)

I’m back home for Christmas and all done with my first rotation. I’m going to start writing it all up tomorrow, 7000 words in 4 weeks. So it seemed like a good time to write a post about what I’ve actually been doing over the last 9 weeks.

I’ve been trying to find out what makes olfactory ensheathing cells (OECs) from neural crest stem cells (NCCs). This means I’ve been looking at which genes are active in these cells at different points in development. The information from an active gene is converted into a messenger molecule (mRNA) and this information is then used to construct a protein, which has a specific role within a cell. mRNA and proteins can be coloured using specific markers.

tMoL: The Meanings of Life - Boxes, little boxes

I’m creating this section as a means for me to blog without having to put in too much effort. In each post I’m going to pick one of the many words and acronyms developed by academics to confuse everyone else, and explain it for everyone to understand, and provide you with a few useful little facts. The first few are going to be pretty easy, words that come up in the media all the time. Words that everyone has heard and probably knows the meaning of but not necessarily some of the more interesting bits.

Cell – I want to start with cells because they are an important part of my work, they are generally most active and undergo the most changes during development. They are also the basis for life and are generally the start point of most discussions of the evolution of life (although actually there was a lot of good stuff before that, which tends to get overlooked). Also I will be talking about them to local school children in a few months and hopefully this will help me to organise some of my ideas.

Lab 1: Only the Nose Knows

Hey

This is the idea that started it all. Telling you all about the different research that I get to do as a PhD student. This post is all about the first lab I'm working in, I started here in early October and have just over a week left until I leave. It's been really a lot of fun, although it did take me a few weeks to really get back into doing work after a very long summer vacation. But the personal stuff can come later. I want to start with the overview. This is the explanation of why I'm doing the project, the stuff I tell people who ask about my work.


(Ed. If anyone's interested, the lab I'm in just released the paper which preceded my project showing that olfactory ensheathing cells are from the neural crest. We also made it into New Scientist.)



Cells from the nose that COULD cure stroke or paralysis! Crazy, right? That’s what I thought too, but it does seem to be true. Cells which guide nerves from the nose into the brain, when transplanted to damaged regions of the spine, help the nerves there to grow through the scar tissue and reconnect with the proper targets.
