High-Aptitude Minds: The
Neurological Roots of Genius
ScientificAmerican.com September 2008
*************************
Researchers have fingered parts of
the parietal and frontal lobes as
well as a structure called the
anterior cingulate as important for
superior cognition. Some studies
suggest that the brains of brighter
people use less energy to solve
certain problems than those of
people with lower aptitudes do. But
under certain circumstances,
scientists...

*************************
A study by NASA's Jet Propulsion
Laboratory shows that the weak
gravitational pull of a nearby
spacecraft could deflect a
hypothetical asteroid 140 meters
across, big enough to cause regional
devastation if it hit Earth....

Solar-Power Breakthrough
Technology Review July 31, 2008
*************************
Daniel Nocera, a professor of
chemistry at MIT, has made a major
advance in chemistry that could lead
to a cheap way to store energy from
the sun, solving one of the key
problems in making solar energy a
dominant source of electricity. He
has developed a low-cost catalyst
that can generate oxygen and
hydrogen from water, and the
hydrogen can...

Dopamine could help the
sleep-deprived still learn
ScienceNews July 31, 2008
*************************
Researchers at Washington
University in St. Louis have found
that activating a receptor for the
neurotransmitter dopamine can erase
sleep-deprivation-caused learning
deficits in fruit flies. The
research is the first to show that
specific molecular changes in the
brain can influence a function of
sleep. While the fruit fly receptor
finding...

Nerve cells made from elderly
patient's skin cells
Nature News July 31, 2008
*************************
Researchers at the Harvard Stem
Cell Institute and Columbia
University have generated motor
neurons from reprogrammed skin cells
(turned into induced pluripotent
stem or iPS cells) of an elderly
patient with amyotrophic lateral
sclerosis (ALS). Patient specific
motor neurons (Harvard University)
They made iPS cell lines by using

New Drugs Mimic Exercise
Technology Review July 31, 2008
*************************
Salk Institute researchers have
found two drugs that mimic or
improve the benefits of exercise,
boosting endurance in mice by
changed metabolic properties of the
animal's muscle. In earlier
research, they genetically
engineered "marathon mice"--animals
with double the running endurance of
normal mice. The superstamina came
by boosting...
