Graphite, more commonly known as pencil lead, could become the next big thing in the quest for smaller, less power-hungry electronics. University of Arizona physicists are making discoveries that may advance electronic circuit technology.

Despite
a century of research, memory storage in the brain has remained
mysterious. Evidence points to synaptic connection strengths among brain
neurons, but synaptic components are short-lived and yet memories can
last lifetimes.Recent has demonstrated a plausible mechanism for
encoding synaptic memory in microtubules, major components of the
structural cytoskeleton within neurons.

On
Wednesday, Jan. 18, astronomers, physicists and scientists from related
fields will convene in Tucson, Ariz. from across the world to discuss
an endeavor that only a few years ago would have been regarded as
nothing less than outrageous: the construction of a virtual telescope
powerful enough to see to the center of our Milky Way.

A slight change in molecular structure introduced by genetic engineering gives crop-protecting proteins called Bt toxins a new edge in overcoming resistance of certain pests, a University of Arizona-led team of researchers reports.

A Princeton University-led study is the first involving humans to show that yawning frequency varies with the season, a disparity that indicates that yawning could serve as a method for regulating brain temperature.

Researchers
have found that melting ice sheets contributed much more to rising sea
levels than thermal expansion of warming ocean waters during the Last
Interglacial Period. The results
further suggest that ocean levels continue to rise long after warming
of the atmosphere levels off.

Biochemists
have hit mosquitoes where it hurts most: their blood meal. Inhibiting a
molecular process the insect’s cells use to direct proteins to their
proper destinations, they have found, causes more than 90% of affected
mosquitoes to die within 48 hours of feeding.

Physicists at the Univ. of Arizona
have proposed a way to translate the elusive magnetic spin of electrons into
easily
measurable electric signals. The finding is a key step in the
development of
computing based on spintronics, which doesn't rely on electron charge to
digitize information.

Meteorites
collected from a British Columbia meteoroid strike in British Columbia
11 years ago are among history’s best preserved. They reveal that
asteroids not only hold the stuff of life, like carbon and amino
acids—the building blocks of protein—they also are
wildly different in the level of amino acids they have. And astronomers
now have a theory as to why.

A
team of researchers from the University of Arizona and Rensselaer
Polytechnic Institute have increased the toughness of ceramic composites
by more than 200% with the use of graphene reinforcements. The graphene
additions arrest the formation of cracks in the ceramic, forcing them
to change direction in three dimensions.
