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.

tMoL: Nucleus

The brain of the cell. It is one of the most well known elements of an animal cell, and is common to all higher organisms (eukaryotes – animals, plants,fungi), as with most structures inside a cell it does not occur in bacteria (prokaryotes). Most DNA in a cell is found in the nucleus, it is the storage centre for all of the information to make more cells. The nucleus is also full of proteins which control which genes are active in a cell and help to pack all of the DNA into such a tiny space. This is how cells are able to become specialised to a specific function, by controlling which genes are active.

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.
