More
than
a
month
after
smoking
pot,
users
may
have
abnormal
brain
patterns,
study
finds
The
study
may
come
as
a
relief
to
marijuana
opponents,
who
previously
had
been
faced
with
a
series
of
studies
suggesting
the
drug
is
relatively
harmless. |
|
Want
sex?
Take
a
number Animals
such
as
clownfish, in seeming violation of every
normal
instinct, patiently
wait
to
become
leaders
of
their
group
before
breeding.
Researchers are learning why this might be.

"Indirect
aggression"
in
media
may
harm
us,
researchers
say We
all
know
that
watching
people
killing
each
other
on
TV
is
supposed
to
be
bad
for
us.
But
what
about
people
being
just
plain
mean
on
TV? |
|
New theories
on
solar
systems
may have little room for other "Earths" New theories may be needed to explain how
the
known
solar systems beyond our own formed, and
the
theories may
dampen hopes for "Earth-like"
planets
there,
researchers
say.
|
|
"Virus"
vaccines
may
create
new
and
worse
diseases,
researchers
warn Some
vaccines, intended to prevent disease, may
create new and more dangerous ones. |
|
Songbirds
may
use
'dawn
chorus'
to
gather
intelligence Songbirds
whose
sweet
tittering
awakes
us
in
the
morning
may
make
an
unexpected
use
for
the
ritual:
spying
on
rivals. |
|
In
insect
societies,
order
through
discipline Wasps
seem
to
"discipline"
each
other
for
not
working
hard
enough.

Ancient
brewery
found Archaeologists
have
found
remains
of
a
large-scale
brewery
from
a
pre-Incan
culture
of
the
first
millennium
AD
in
Peru. |
|
Black
holes
looking
less
and
less
'black' Black
holes,
traditionally
assumed
to
be
sullen,
dark
objects,
may
actually
give
off
signals
that
betray
what
fell
inside
them.

How
'near-death experiences' change the brain After
brushes with death, some people report newfound peace and
spiritual awakenings. Researchers are learning
what brain changes accompany these experiences. |
|
Does females'
promiscuity reduce our height differences? One researcher thinks that may be the case. It seems to be the pattern among our ape relatives, at least, he says. |
|
Beauty and ugliness stimulate the same brain region Humans use the same brain area, and very possibly the same cells, to perceive both beauty and
beastliness, scientists report.
|
|
Fish who share our personal shortcomings? Add this to that file. Rainbow trout offended by a stronger member of their group are smart -- or pathetic -- enough to vent their aggression on someone weaker.
|
|
Less may be more when it comes to brain use When using your brain, less may be more, a study has found. After bright people learn a mental task, their brains perform it using less energy, compared to dimmer peers in the same situation.
