Brain Cancers
NEW
Sept. 05,
2008
HHMI
investigators have detected a multitude of broken, missing, and
overactive genes in pancreatic and brain tumors, in the most
detailed genetic survey yet of any human tumor. Some of these
genetic changes were previously unknown and could provide new
leads for improved diagnosis and therapy for these devastating
cancers.

100-year
study asks how forest management affects animals, plants
NEW
Sept. 04,
2008
A group of
researchers led by Purdue University has begun to sample data for
a planned 100-year study designed to develop better forest
management methods and measure how such practices affect resident
plant and animal species. "Our main goal is to find out how
to most effectively regenerate oak and hickory forests, while
examining the impact these treatments have on the whole
ecosystem," said Cortney Mycroft, project manager for the
study, called the "Hardwood Ecosystem Experiment."

A
Fine-Tooth Comb to Measure the Accelerating Universe
NEW
Sept.
05, 2008
Astronomers
use instruments called spectrographs to spread the light from
celestial objects into its component colors, or frequencies, in
the same way water droplets create a rainbow from sunlight. They
can then measure the velocities of stars, galaxies and quasars,
search for planets around other stars, or study the expansion of
the Universe. A spectrograph must be accurately calibrated so
that the frequencies of light can be correctly measured. This is
similar to how we need accurate rulers to measure lengths
correctly.

New
Algorithm Significantly Boosts Routing Efficiency of Networks
NEW
Aug. 19,
2008
A
time-and-money-saving question shared by commuters in their cars
and networks sharing ever-changing Internet resources is: “What’s
the best way to get from here to there?” A new
algorithm developed by computer scientists from UC San Diego’s
Jacobs School of Engineering helps answer that question, at least
for computer networks; and it promises to significantly boost the
efficiency of network routing.
