Good Morning,
Check out the first article for more details on a neat
medical tool that is making screening for fevers less of
a hassle in hospitals. It is that sort of technology that
is really going to be useful in that it will speed up
productivity without lowering quality in medical facilities.
Until Next Time,
Erin

Study: Infrared fever detectors effective
OMAHA - U.S. scientists say the use of infrared detection
systems is a fast and effective way to identify fever in
patients at hospitals and clinical settings. Researchers
at the University of Nebraska Medical Center said they
found such a fever screening tool useful in providing
split-second, non-contact skin temperature measurements.
Fever is a primary symptom of seasonal influenza, H1N1
avian influenza and other infectious diseases. Dr. Angela
Hewlett and colleagues said they evaluated the OptoTherm
ThermoScreen in the emergency department of the Nebraska
edical Center to test the tool's viability in a practical
clinical setting. The system employs a thermal imaging camera
to measure skin temperature by detecting and quantifying the
infrared energy being emitted from a person's face. "The
purpose of fever screening is to protect patients," said
Hewlett, an assistant professor of infectious diseases. "This
technology allows clinicians to rapidly screen people for
fever, so that incoming patients and visitors who may be ill
can be identified quickly and reduce the danger of spreading
diseases ? in the hospital." According to the study, if fever
was not detected there was a 97 percent chance there was no
fever present, making the ITDS a useful tool for quick fever
screenings. The study was presented in Atlanta during last
week's International Conference on Healthcare-Associated
Infections.

Jupiter's lack of atmospheric neon studied
BERKELEY, Calif. - U.S. scientists hypothesize Jupiter's
interior conditions cause helium to condense into droplets,
explaining the scarcity of neon in the plant's atmosphere.
University of California-Berkeley scientists say neon dis-
solves in the helium raindrops and falls towards the deeper
interior where it re-dissolves, depleting the upper layers
of both elements, consistent with observations. "Helium con-
denses initially as a mist in the upper layer, like a cloud,
and as the droplets get larger, they fall toward the deeper
interior," said post-doctoral fellow Hugh Wilson, co-author
of the study. "Neon dissolves in the helium and falls with
it. So our study links the observed missing neon in the atmo-
sphere to another proposed process, helium rain." Wilson's
co-author, Assistant Professor Burkhard Militzer, noted rain
as we know it on Earth is actually an imperfect analogy to
what happens in Jupiter's atmosphere. He said the helium
droplets form about 6,000-8,000 miles below the tops of
Jupiter's hydrogen clouds, under extraordinarily high pres-
sures and temperatures that make the "rain" really droplets
of fluid helium mixed with neon falling through a fluid of
metallic hydrogen. The researchers say their study will help
refine models of Jupiter's interior and the interiors of
other planets. The research is detailed in the journal
Physical Review Letters.
Discovery to be launched next Monday
CAPE CANAVERAL, Fla. - NASA officials say they've determined
space shuttle Discovery's equipment and systems are ready
for its 13-day flight to the International Space Station.
The STS-131 mission -- the second of the last five shuttle
missions -- will lift off April 5 at 6:21 a.m. from the
Kennedy Space Center in Florida. Discovery will deliver
equipment and supplies to the space station, including the
Leonardo multipurpose logistics module, nicknamed "the moving
van" by NASA. It will be temporarily attached to the station,
filled with supplies, a new crew sleeping quarters and sci-
ence racks that will be transferred to the station's labora-
tories. Officials said STS-131 will include three spacewalks
to remove and replace a gyroscope on the station's truss,
install a spare ammonia storage tank and retrieve a Japanese
experiment from the station's exterior. Commander Alan
Poindexter and his crew -- Jim Dutton Rick Mastracchio,
Dottie Metcalf-Lindenburger, Stephanie Wilson, Clay Anderson
and Japan Space Agency astronaut Naoko Yamazaki -- are to
arrive at the space center Thursday morning to begin their
final preparations. NASA said the mission will be the first
trip into space for Dutton, Lindenburger and Yamazaki.
STS-131 will be Discovery's 38th mission and the 33rd shuttle
flight dedicated to station assembly and maintenance, the
space agency said.

University of Illinois gets new microscope
CHICAGO - The University of Illinois at Chicago says it will
become the first university in the world to have one of a
new generation of electron microscopes. University officials
said the new "aberration-corrected scanning transmission
electron microscope," nicknamed STEM, will provide views of
up to three times the sharpness of existing electron micro-
scopes. Assistant Professor Robert Klie was awarded a $2
million National Science Foundation grant to acquire the
sophisticated instrument that will allow scientists see
individual atoms, helping them better understand how mater-
ials function. "By improving the resolution we can decrease
the blurring, so we'll see atoms that were previously indi-
stinguishable," said Klie, who previously worked with a
comparable instrument at the Brookhaven National Laboratory.
Unlike optical microscopes that use visible light to illumi-
nate a sample, STEM views samples using a carefully con-
trolled beam of electrons accelerated to nearly the speed
of light, Klie said. With aberration correction, the STEM
will provide sharper images and have reduced electron energy
blur, which improves color distinction. "With the aberration
correctors, you can correct for the decreased resolution of
slower electrons and still get the atomic resolution, even
at these low acceleration voltages," Klie said. The new
instrument will mark the first significant upgrade to the
university's electron microscopy facility in more than a
decade, giving students unparalleled training opportunities,
Klie said.
