This
guided
tour
of
the
dinosaur
known
as
Dilophosaurus
is
narrated
by
the
discoverer
of
Dilophosaurus,
Sam
Welles,
formerly
a
professor
at
the
University
of
California
Museum
of
Paleontology
(UCMP).
Links

Dr.
Wells'
description
of
the
discovery,
as
well
as
the
morphology
and
habits
of
the
creature.
He
also
compares
and
contrasts
the
real
animal
with
the
one
shown
in
the
movie

In
modern
organisms,
there
is
a
division
of
labor
between
two
kinds
of
molecule:
DNA,
which
stores
and
transmits
genetic
information,
and
proteins,
which
do
all
the
work.
They
are
connected
by
the
genetic
code,
whereby
DNA
specifies
what
kinds
of
proteins
can
be
made.
This
process
of
translation
is
well
understood,
but
it
is
far
too
complicated
to
have
arisen
by
chance
in
the
primitive
oceans.

This
video
lecture
explores
the
chemistry
of
the
hordes
of
molecules
in
the
interstellar
medium
revealed
by
radioastronomical
observations
of
our
galaxy.
Extremely
fast
reactions
result
in
the
high
abundance
of
complex
organic
compounds
in
the
space
between
the
stars.
The
chemistry
of
the

illustrates
that
complex

occurs
under
totally

explains
research
on
the
shark
species
who
migrate
north
to
Massachusetts
as
the

warm
in

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

changes
he
has
observed
at
an

ridge
2,500
meters
deep
in
the
Pacific
Ocean.
The
ongoing
studies
from
1991
of
this
unique

are
dramatically
altering

an
oceanographer
describes
studies
that

The
Southern
Ocean,
which
surrounds
Antarctica,
is
a
key
region
in
determining
global
climate.
This

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
