A new domain of life – Plenty more bugs in the sea - and the vocabulary

Tantalising – possible, tempting
gap – space, hole
lumps – groups
arguably - not certain, can be disputed
creatures – e.g. animals
disease – sickness
crucial – essential, very important
ring – circle
float around – move, but without any power of their own
methane – a gas
stretch back – go back, stretch = make longer
in the shadows – not highlighted, not in the sunlight
missed – not seen
tools – instruments
suggest – imply

draw a conclusion (conclusion was drawn) – deduce, answer, find a solution
having been fired – lost his job, thrown out, made redundant, sacked
wider - broader, bigger
hard cash – readily accessible money
killer app – revolutionary application, application that beats the competition, major advantage
shotgun – a gun for shooting birds, it fires pellets, not bullets
handle – deal with, process
stitches – sews, joins
overlaps – parts that duplicate, one part is the same as another
trick – clever solution
sample – representation, partial collection, example
hot springs – natural sources of hot water (like thermal baths)
guts - intestines
combing - analysing in detail
accrete – accumulate
ubiquitous – found everywhere, omnipresent
and lo – old English - “what a surprise” - “look”
novel – new
uncharacterised – not defined
lacuna – gap, space, lack
winnow – extract in small quantities

and of course the important difference between: known unknown and unknown unknown

What are the current 3 domains of life ? - Eukaryotes, Bacteria, Archaea
Where was evidence of the new domain found ? In the sea
What is the new evidence ? – parts of the evolutionary trees of 2 genes – RecA RpoB - do not fit with existing ones -
so either the trees are wrong or this is a new domain of life...
Why did Craig Ventner have time to “cruise the world” ? - he had no other job, he was paid to leave Celera Genomics
