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.

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.

SOS: Save our Science - Yet More Alien Bacteria. Really!

I saw James Watson last night! and I have his autograph. :D He was in London, in conversation with Brenda Maddox, who wrote Rosalind Franklin's biography. It was fascinating, although I have to admit that he was clearly on his very best behaviour and kept the outrageous comments to a minimum. I'd also like to take this as my excuse for any 'enthusiastic' comments in the post below, which is a great peiece of storytelling. This week was also my first outreach talk to school children, I think it went rather well, although I'll be writing much more on that in a few weeks.

 

OK, so this is another story that I was asked to write (Yay!). Once again there have been reports of alien bacteria in meteorites (that’s the third time in 14 years, if you’re counting).Here is the latest story, I suggest you read it first as it makes what I’ll be saying more surprising. Go on, I’ll wait. Sounds good doesn’t it, highly acclaimed doctor with a paper in a prestigious sounding journal, with authoritative quotes and everything. Not only that but the journal seems to have gone to great lengths to ensure extensive peer reviewing of the findings before publishing. Well, as with many stories that get NASA plastered to them, it’s got a lot of people rather riled up and for a lot of different reasons. Read on and I’m sure you’ll see why.

This is a fantastic story, I’ve never seen so many mistakes made by so many people in so many different ways, it’s quite a feat of engineering really. Also it does go to show that some people really do never learn. The roots of this story lie all the way back in 1997 when NASA scientists reported finding bacterial fossils in a meteorite from Mars.

This astonishing and revolutionary finding was reported by Richard B. Hoover who works at NASA’s Marshall Space Flight Centre. This was discounted shortly afterwards when it became apparent that the structures observed were probably contaminants from the time the sample spent on Earth before being studied. Now some people would learn from such a colossal mistake that was a huge embarrassment for NASA and Hoover personally.

Hoover, however, is made of stronger stuff. After his error in 1997 I’d like to say that he improved his working scheme, ensuring all samples were properly sterilised and cross checked before announcing proof of alien life to the public. But he didn’t. He returned in 2007, although with less impact (mainly due to lack of a successful publication), to say that he really had found life, this time in a totally different type of meteorite. Thankfully this time he attracted less attention.

Now, to the delight of many, Richard B. Hoover has returned to the public stage, thanks in no small part to the lovely people at FOX news, with another attempt. He’s still looking at the same rocks from 2007 but this time he REALLY thinks he’s got it.

SOS: Save our Science - Seeing Sharks!!

This is the end of my first week in the second lab, it's pretty fun so far, quite enjoying the variety of things I've become involved in and will hopefully get some very exciting data. It's going to be a busy term though. Anyway, more on that later. Here's some fishy news from Australia!


It is a commonly quoted fact that sharks can smell a single drop of blood in over 100 litres of water. As a top predator a shark needs highly developed senses to hunt, so it is surprising that many species are probably completely colour blind! Sharks still have excellent vision, but it is monochromatic i.e. Black and white.
