Nice. forgot there was a follow-up "why is it used" question when posting my answer!

comment Is there a physiological difference between love and infatuation?
The distinction (if there even is one) is likely to be at the psychological level, rather than biological... but that's just my gut feeling - I've not read that anywhere!

comment Is there a physiological difference between love and infatuation?
My point was simply that the interpretation of the words is quite subjective, unless you define them in the question. E.g. dictionary.com definition #1 for infatuation is [to inspire or possess with a foolish or unreasoning passion, as of love], and love as [a profoundly tender, passionate affection for another person]. Is this how you interpret them? Or would you say they feelings are more divergent? In my opinion you could probably use either definition for each word, depending on the context.

comment Terminology question: the scope of an allele in an organism
I have never seen a term applied to that - although there was a question on here a few weeks ago about something similar. Can't find it now though!

Could you elaborate on what you feel the distinction between the 2 is? Infatuation could just mean obsession, whereas love could imply a more physical attraction?

Hi all. See this article in Nature - very interesting.

comment Difference between genetic engineering and synthetic biology
... however this is just my interpretation of things! I have not seen a concrete definition, so I may well be mistaken. Or indeed, there may not be a concrete definition, and this is quite subjective (like 'bioinformatics' vs 'computational biology'. People agree there is a distinction, but not on where the line is drawn).

comment Difference between genetic engineering and synthetic biology
Interesting point. 'Silent' mutations (those that do not affect the protein sequence) could still affect regulation of transcription - for instance miRNA binding or alternative splicing (this is very situation dependent of course, but I'm just saying that 'silent' mutations don't necessarily have no effect). With mutagenesis I would say it's genetic engineering, as there is no 'synthetic' element to the DNA modification, other than it is done under experimental conditions... an analogous experiment using a manufactured/custom sequence of DNA inserted into the genome would be 'synthetic' IMO.

comment Difference between genetic engineering and synthetic biology
I don't think they mean synthetic as in 'made in the lab using PCR', as for all genetic engineering PCR will be essential at some point (at least, that is how I interpret it). The term synthetic probably is used to refer to specific sequences of nucleotides that are not naturally formed (i.e. they are de novo, synthetic sequences).
