The
Southern
Ocean,
which
surrounds
Antarctica,
is
a
key
region
in
determining
global
climate.
This
video
lecture
presents
data
revealing
that
the
Southern
Ocean
is
undergoing
an
alarming
warming
trend
that
may
affect
climates
in
the
Pacific,
Atlantic,
and
Indian
Oceans.
What
does
the
Antarctic
region
tell
us
about
our
future?
Is
Antarctica
especially
sensitive,
so
that
now
it
serves
as
an
early
warning

This
video
lecture
includes
discussion
of
the
physical
properties
of
gases
and
demonstrates
how
air
is
liquefied.
Liquefied
gases
are
a
key
resource
for
survival
with
an
amazing
range
of
applications
and
there
are
now
few
industries
which
are
not
in
some
way
dependent
on
this
major
raw
material.

Biology
operates
at
two
levels:
the
large
scale
which
we
can
see
and
the
underlying
microscopic
one.
This
video
lecture
describes
how
intermolecular
forces
cause
protein
arrays
to
self-assemble,
enabling
nature
to
fabricate
the
large
scale
components
of
living
systems.
The
lecturer
explains
how
scale,
forces
and
information
cooperate
to
form
complex
structures.
There
are
demonstrations
of

This
lecture
explains
research
on
the
shark
species
who
migrate
north
to
Massachusetts
as
the
ocean
waters
warm
in
May
and
June.
Among
the
species
are
oceanic
sharks
such
as
the
blue,
mako
or
basking
sharks;
coastal
species
such
as
sandbar
sharks,
spiny
and
smooth
dogfish;
or
tropical
species
such
as
tiger
and
hammerhead
sharks;
and
the
