Thinking ahead: Bacteria anticipate
coming changes in their environment
PhysOrg.com June 9, 2008
*************************
A new study by Princeton University
researchers shows for the first time
that bacteria don't just react to
changes in their surroundings --
they anticipate and prepare for
them. The findings, reported in the
June 6 issue of Science, challenge
the prevailing notion that only
organisms with complex nervous
systems have this ability. In
addition...

beta-endorphin peptide (BEP) "feel
good" hormone -- released during
exercise, a good conversation, and
many other aspects of life that give
humans pleasure -- play a roles in
regulating the stress response and
immune functions to control tumor
growth and progression. To...

'Party chat' brain filter
discovered
New Scientist news service June 10, 2008
*************************
Researchers conducting brain scans
of people listening to multiple
sounds, say that the secondary
auditory cortex -- located in the
temporal lobe at the side of the
head -- does much of the work in
filtering out a single thread of
conversation from a tangle of
similar background noises (the
"cocktail party...

*************************
Eating food rich in omega-3 could
help some people avoid age-related
macular degeneration, a University
of Melbourne research review
suggests. Dr. Elaine Chong, who led
the research, said that omega-3
fatty acids were a vital component
of the retina, and it was possible
that a shortage of the chemical
could "initiate" the disease as
retinal...

Hints of structure beyond the
visible universe
New Scientist news service June 10, 2008
*************************
Colossal structures larger than the
visible universe -- forged during
the period of cosmic inflation
nearly 14 billion years ago -- may
be responsible for a strange pattern
seen in the big bang's afterglow,
says a team of cosmologists. If
confirmed, the structures could
provide precious information about
the universe's earliest...

Researchers in Sweden and Japan
have developed "nanopaper"--a much
stronger paper, made from much
smaller fibrils of cellulose tens of
nanometers wide, with a tensile

Anticipating the Future to 'See'
the Present
New York Times June 10, 2008
*************************
Scientists argue that the brain has
evolved to see a split second into
the future when it perceives motion.
Because it takes the brain at least
a tenth of a second to model visual
information, it is working with old
information. By modeling the future
during movement, it is "seeing" the
present. This is a general principle
the brain applies...
