A New Domain of Life
A new domain of life – Plenty more bugs in the sea - and the vocabulary
Tantalising – possible, tempting
gap – space, hole
lumps – groups
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
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)
combing - analysing in detail
and lo – old English - “what a surprise” - “look”
accrete – accumulate
ubiquitous – found everywhere, omnipresent
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

Superbugs
Sound a warning – make an alarm
mould – type of fungus
misuse – use badly
prompt – inspire, provoke
stand alongside – be together
(penicillin + antibiotics it inspired) + vaccinations = greatest medical inventions
strain - sub-species
a fair understanding a good understanding
dealt with worked on, tackled, handled, overcome
laziness not energetic, opposite of active
sheer ordinary, only
nullify counteract, make zero
threat menace
gnaw chew, eat e.g. a bone
gnaw away slowly eat, slowly reduce
press push
colds mild sickness, (cough, sneeze, runny nose)
seldom harmed not often injure
to rid to send away, to throw out, to expel
breeding grounds areas that encourage reproduction
prescribed given
finish the course take all the pills
over the counter for example - in a shop
reaction vessel like a test tube in a laboratory, a place to promote reactions
nor (neither, nor – not one, not the other)
livestock animals on a farm
healthy not sick
chronic extreme
worse bad, worse, worst
troublesome difficult, make trouble
vast very big
calculus mathematical calculation, algorithm
think-tank organisation of clever people producing new ideas
force to turn make someone change
point out highlight
drug bill cost of drugs
ubiquity found everywhere
dearer more expensive
burden load, weight to carry
resonance relevance
pump out empty a container of liquid
manage the trick do something difficult
cosseted protected from harm (like a baby)
wholly completely
laid out presented, explained
elevated higher
rein in control, decrease ( a rein is part of a harness, to control a horse)
dosing measures
diluted added water, less pure
a decade hence in 10 years
Aid agencies, charities – Caritas, e.g. Oxfam, Unicef, Red Cross...
safeguard safety measures
counterfeit fake
substandard low quality – below standard
unwitting innocent
mushrooming growing very quickly, like a mushroom
popped taken, consumed
paramount most important
sterner more strict
against the grain like cutting meat or wood – one direction is easy (with the grain) the other direction is hard (against the grain)
weapons instruments for fighting (swords, guns, etc...)
armoury store for weapons
slogan motto, saying, statement
cure make better
breakthrough radically different
never been bettered remains the best
huge sums lots of money, $$$$$$
empty-handed without success
target aim, goal, objective
screening testing
pipeline series ( a pipeline carries liquids, but in this case is the series of drugs in various stages of testing before commercial release)
forgivable not hold responsible
so less forgivable – more guilty
boutique specialised
emporia large organisation
gains profits, advantages
soluble can be solved

Biotech and Science Students - Articles
Pore – small hole (normally in skin e.g. sweat pore)
landmark - reference point – originally e.g. a cathedral, a castle
undertake - do, try to finish a challenge
cheap – not expensive
strand – string, like a chain
pioneer – explorer, someone who explores new territory
amplification – copy millions of times
tag - label
bottleneck – restriction
label – sign, indication
state-of-the-art – most modern practice, latest way of doing something
chunk – block, piece
speed up – go faster – e.g. “speed things up”
overlap - a small portion the same, partially cover
to piece - to put parts together, join parts,
cause a drug to work - makes a drug function
cope - deal with, handle, able to tolerate
How much did it cost to sequence the first genome ?
How long does it take now ?
What is, currently, the main constraint to sequencing ?
Coax - encourage
nanometre = 1/ 1,000,000,000 metre
pass through – allow to go past
negative charge – negative electrical current
disruption - interference
crucially – most importantly
flow of current – speed of electrons' movement
thread – insert (e.g. thread cotton through the eye of a needle)
cleave – to split, to open a gap
feed through – push through
cartridge – container (e.g. for ink in a printer)
lab on a chip – automated chemical analysis using microchips, simultaneous analysis
microfluidics – science of liquid flow at a micro level
detection – discovery
plug in – connect (e.g. plug a computer into a network)
rack-like – similar to shelves
cabinet – item of furniture that is a container (e.g. cupboard, wardrobe)
carry out - execute (“carry out large scale analysis” = analyse on a large scale)
commercial launch – ready to be sold
thickness – depth, opposite of thinness (depth !)
What creates nanopores in cell membranes ?
What is a lipid bilayer ?
How can you tell the type of molecule as it goes through the bilayer ?
What's the problem with exonuclease sequencing ?
Why is the velocity of the strand going through the nanopore important ?
Ù
Ratchet – mechanical system allowing only one direction
address, tackle – undertake, deal with, work on, try to resolve
constriction – partial block, restriction, narrowing
simultaneous – at the same time
dispense with – get rid of, eliminate
gain ground - become popular, become accepted (a military analogy – to capture territory)
solid-state – unchanging, like metal - so not fluid, not biological
