Metabolism appears in lab without cells

4 posts in this topic

http://www.newscientist.com/article/dn25471-spark-of-life-metabolism-appears-in-lab-without-cells.html#.U2BWdVfNF2A

Now, I love science, and usually 'get it' when I read about it.

But could someone dummy down this for me? Maybe its the 10 hour shifts and I feel dumb and tired, could someone here just dummy it down and explain this to me? At first i thought it was something like.. I dunno, the first cells of life through mishmash of chemicals naturally on earth perhaps when life first appeared.. and so i was excited, but then i read it, it confused me.. and i do not think it is what I thought it was.

SOOOO

dummy it down?

Thank you ahead of time, and if i am slow in responding, i am either 1. sound asleep or 2. at work AGAIN.

Hey Willowdreams. You have the gist of it right. This about abiogenesis and the first spark of life. Life can't have started with anything as complex as cells. Cells must have developed much later. The first spark of life must have been chemical polymers that were able to replicate themselves. DNA couldn't have come first as it can't replicate itself. RNA is one candidate but it may have been something simpler. Something that would blur the line between life and non-life and apparently these people are on that trail. I'm no expert on this either but, like you I am fascinated by every aspect of science

From the linked article:

Remarkably, the discovery was an accident, stumbled on during routine quality control testing of the medium used to culture cells...

Heh, that's how many good scientific discoveries are made!

ETA: Thanks for the article, Willowdreams, it was an interesting read.

thank you, i am glad i wasnt too far off the mark then.. it is like i get it.. but other times i feel slow on the uptake on it.
