How often have you read a story that a
friend or family member has sent
you
？
Very likely you would
have skipped the news had it not been
pointed
out to you.
Traditionally
newspapers
and
famous
TV
channels
have
been
our
source
of
authentic
these
days
with
the
popularity
of
social
media
，
sharing
stories
is
increasingly
becoming
a
favorite
source
of
fact
，
research
suggests
that
more than half the
people
get their news today from social media such as
Facebook
，
Twitter and Google.
Social media sites often aggregate
contents for us to see based on trending
topics
—
stories
that have been viewed by many others as well as
based on our own
past
searches and analysis of our lik
es and
you have liked kittens in
the
past
，
you may have noticed
that you are seeing more
news
，
blogs and analysis
about kittens all of a sudden.
While
advocates
of
free
speech
do
not
want
to
control
any
voice
，
it
is
certainly
harmful when it is difficult to
separate truth from e the influence
of
fake(
虚假的
) news when it
begins to affect our own
ting a piece
of
news
，
patients
could
very
easily
fall
for
wrong
diagnosis;
elders
could
give
money
to
cheats
and
reputation
of
perfectly
upright
citizens
could
be
easily
about
when
we
research
for
a
school
project
and
base
our
analysis
on
false
information
or news?
Mark Zukerberg has
finally acknowledged the several projects that
the company is
considering
，
Facebook is
trying to take powerful measures to crack
down
on
false
would
include
warning
labels
on
fake
news
also
makes
a
lot
of
profits
from
and
Facebook
have
said
they
will
limit
advertising profits on
their network from such sites.
The
bottom
line
—
don't
believe
every
word
of
what
you
more
research
from
multiple (
多样的
)
sources to
ensure that the news is
indeed true before you share
with
others.

B
Run out of cooking oil or need some
dressing for your salad
？
The
solution may
2
be
insects
from
your
backyard
！
Scientists
are
turning
insects
into
a
source
of
healthy
though
insects
are
a
food
source
in
some
parts
of
the
world
，
to
many
people
，
the
thought of eating them is very disgusting.
“
In the western
countries
，
there is no
culture of eating entire
insects
，
so
when
the idea is to use the protein in powder as an
ingredient
，
people might tend
to
receive
this
protein
better even
if
they
cannot
see
it
，”said
researcher
Daylan
Tzompas?Sosa，
Wageningen
University
，Netherlands.“There
are
many
uses
for
the
oil
in general
，
but we
are investigating the use of these oils for a
food
，
as a food
ingredient.”
The
Mexican researcher
，
working
in the Netherlands
，
said
insects are a great
source
of
heart?healthy
omega?3
fatty
acids，
which
can
help
treat
anxiety
disorder
g up the increased reliance on insects
is the United Nations Food
and
Agriculture
a
2013
report
，
the
UN
agency
allowed
the
cultivat
ion
of
bugs
as
a
food
source
，
saying
it's
environmentally
friendly
and
could
boost
the
world's food production.
There are clear reasons why experts
advise people to eat the s
say
insects
require
little
food
to
grow
and
the
backyard
can
be
a
good
place
to
raise
there's
no
s
hortage
of
protein?rich
insects，
which
contain
fat
，
vitamins
，
fiber and
minerals.
Researchers
say
different
bugs
provide
unique
tastes
and
textures.“This
is
very
liquid and it has a
different color
，
so this can
be used as a dressing for example
and
it's
easy
to
use
and
this
can
be
used
for
example
for
pastry
，
because
for
pastry
you
need hard fats
，”stated
Tzompas?Sosa.
But not all
insects produce good aches don' bug oils must be
tested to ma
ke sure they are
safe to getting over the “ick factor”
may be a bigger challenge.
