A novel way of making computer memories, using bacteria

FOR half a century,
the (1) __________of progress in the computer industry has been to do more
with
less.


Moore's
law
famously
observes
that
the
number
of
transistors
which can be crammed into a given space (2)__________ every 18 months.


The amount of data that can be stored has grown at a similar rate.



Yet
as
(3)__________
get
smaller
,
making
them
gets
harder
and
more
expensive.


On
May
10th
Paul
Otellini,
the
boss
of
Intel,
a
big
American
chipmaker
, put the price of a new chip factory at around $$10 billion.


Happily
for those that lack Intel's resources, there may be a cheaper option
—
namely to
mimic
Mother
Nature,


who
has
been
building
tiny
(4)__________,
in
the
form of living cells and their components, for billions of years, and has thus got
rather good at it.


A paper published in Small, a nanotechnology journal , sets
out the latest example of the (5)__________.



In it, a group of researchers led by Sarah Staniland at the University of Leeds, in
Britain,
describe
using
naturally
occurring
proteins
to
make
arrays
of
tiny
magnets,


similar
to
those
employed
to
store
information
in
disk
drives.


The researchers took their (6)__________ from Magnetospirillum magneticum,
a bacterium that is sensitive to the Earth's magnetic field thanks to the presence
within its cells of flecks of magnetite, a form of iron oxide.


Previous work has
isolated
the
protein
that
makes
these
miniature
compasses.
Using
genetic
engineering, the team managed to persuade a different bacterium
—
Escherichia
coli,
a
ubiquitous
critter
that
is
a
workhorse
of
biotechnology
—
to
(7)__________ this protein in bulk.



Next, they imprinted a block of gold with a microscopic chessboard pattern of
chemicals.


Half
the
squares
contained
anchoring
points
for
the
protein.


The other half were left untreated as controls.



They then dipped the gold into a solution containing the protein, allowing it to
bind
to
the
treated
squares,
and
dunked
the
whole
lot
into
a
heated
(8)__________ of iron salts.


After that, they examined the results with an
electron microscope.



Sure
enough,
groups
of
magnetite
grains
had
materialised
on
the
treated
squares, shepherded into place by the bacterial protein.


In principle, each of
these magnetic domains could store the one or the zero of a bit of information,
according to how it was polarised.



Getting from there to a real computer memory would be a long road.



For a start, the grains of magnetite are not strong enough magnets to make a
useful
memory,
and
the
size
of
each
domain
is
huge
by
modern
computing
(9)__________.


But Dr Staniland reckons that, with enough tweaking, both
of these objections could be dealt with.



The (10)__________ of this approach is that it might not be so capital-intensive
as building a fab.



Growing things does not need as much kit as making them.



If
the
tweaking
could
be
done,
therefore,
the
result
might
give
the
word
biotechnology a whole new meaning.


A) components





B) advantage





C) standards





D) compliments





E) essence





F) inspiration





G) disadvantage





H) doubles

Nice juicy Apple


ALTHOUGH he is still (1)__________ things up at Dell, an
ailing computer-maker
, Carl Icahn has found time to tilt at another tech titan.
On August 13th the veteran shareholder activist (2) __________that he had
built up a stake in Apple, though he stayed mum about exactly how many shares
h
e had bought. Mr Icahn’s intentions, however
, are crystal clear: he wants the
consumer-electronics behemoth to expand plans to return some of its whopping
$$147 billion of cash and marketable securities to shareholders.


Mr Icahn is
also after more money at Dell, where he has been lobbying with allies against a
(3)__________ buy-
out plan put forward by Michael Dell, the firm’s founder
,
and
Silver
Lake,
a
private-equity
firm.
His
pressing
has
already
forced
the
buy-out group to raise its initial offer by over $$350m, to $$24.8 billion and he has
taken his (4)__________ to the courts in a bid to extract an even higher price.


Other tech firms have been attracting the attention of activist investors too.
Earlier this year ValueAct Capital, an investment fund, said it had built up a $$2
billion
stake
in
Microsoft.
Jaguar
Financial,
a
Canadian
bank,
has
been
(5)__________
fresh
thinking
at
troubled
BlackBerry,
which
announced
on
August
12th
that
it
is
exploring
various
(6)
__________options,
including
alliances and a possible sale. And Elliott Management, a hedge fund, has been
lobbying for change at NetApp, a data-storage firm that it thinks could do more
to improve returns to (7)__________.


One reason tech firms have found
themselves in activists’ crosshairs is that, like Apple, some built up big cash
piles
during
the
economic
downturn
and
have
been
slow
to
use
the
money.
Financiers hope to get them to loosen their purse-strings faster and to pocket
some of the cash. Mr Icahn wants Apple to increase and (8)__________ a share
buy-back programme that is currently set to return $$60 billion to shareholders
by the end of 2015.


Another reason that tech firms make tempting targets
for shareholder activists is that swift changes in technologies can trip up even
the mightiest. Witness the case of Microsoft, which ruled the roost during the
personal-computer era but has struggled to adapt to a world in which tablets
and smartphones are all the rage. Investors hope to mint money by pushing
companies
to
change
more
rapidly
in
response
to
such
upheavals
in
their
markets.


The
rewards
can
be
substantial.
Egged
on
by
Third
Point,
an
activist
hedge
fund,
Yahoo
(9)
__________Marissa
Mayer
as
its
new
chief
executive in July 2012. By the time she celebrated a year in the job last month,
the troubled web giant’s share price had
risen by over 70%. In July the hedge
fund sold a big chunk of shares back to Yahoo. Mr Icahn thinks Apple’s share
price, which closed at $$499 on August 14th, could soar too if the firm follows his
advice
on
buy- backs.
He
tweeted
this
week
that
he
had
had
a
“nice
(10)__________” with Tim Cook, Apple’s boss, about his idea, though he did
not say what Mr Cook thought of it. If Apple drags its feet, expect things to turn
nasty.


A) shareholders


I) appointed


B) strategic


J) race


C) communication


K) revealed


D) battle


L) method


E) conversation


M) accelerate


F) encouraging


N) proposed


G) exciting


O)



H) stirring

(3)

It isn't just the beer that (1)__________ to beer bellies. It could also be the
extra
calories,
fat
and
unhealthy
eating
choices
that
may
come
with
(2)
__________drinking.


A
recent
study
found
that
men
consume
an
(3)__________ 433 calories (equivalent to a McDonald's double cheeseburger)
on days they drink a moderate amount of alcohol. About 61% of the caloric
increase comes from the alcohol itself. Men also report eating higher amounts of
saturated fats and meat, and less fruit and milk, on those days than on days
when
they aren't drinking,
the study
showed.


Women
fared a
bit
better
,
taking in an extra 300 calories on moderate- drinking days, from the alcohol and
eating
fattier
foods.
But
women's
increase
in
calories
from
additional
eating
wasn't
statistically
significant,
the
study
said.


'Men
and
women
ate
less
healthily on days they drank alcohol,' said Rosalind Breslow, an epidemiologist
with the federal National Institute on Alcohol Abuse and Alcoholism and lead
author of the study. 'Poorer food choices on drinking days have public-health
(4)__________,' she said.

The findings dovetail with controlled lab studies in
which
(5)__________
generally
eat
more
food
after
consuming
alcohol.
Researchers
suggest
that
alcohol
may
enhance
'the
short-term
rewarding
effects' of consuming food, according to a 2010 report in the journal Physiology
&
Behavior
that
reviewed
previous
studies
on
alcohol,
appetite
and
obesity.

But other studies have pointed to a different trend. Moderate drinkers gain less
weight over time than either heavy drinkers or people who abstain from alcohol,
particularly
women,
this
research
has
shown.
Moderate
drinking
is
(6)
__________having
about
two
drinks
a
day
for
men
and
one
for
women.


'People
who
gain
the
least
weight
are
moderate
drinkers,
regardless
of
[alcoholic]
beverage
choice,'
said
Eric
Rimm,
an
associate
professor
of
epidemiology and nutrition at Harvard Medical School and chairman of the 2010
review
of
alcohol
in
the
federal
dietary
(7)__________.
The
weight-gain
