Researchers from the Georgia Tech College of Computing, working in partnership with the Centers for Disease Control and Prevention (CDC), have developed a digital data tracking system to assist low-resource clinical laboratories in developing countries.

Good balance and mobility are essential to help you perform most activities involved in every-day life, as well as many recreational pursuits. Keeping your balance is a complex task, involving the co-ordination between a person's muscles and sensors which detect balance and are part of the nervous system. In older people many factors such as reduced muscle strength, stiff joints, delayed reaction times and changes in the sensory system all add up to reduce a person's ability to keep in balance.
The latest news and discoveries from the science of fluid motion will be featured at the 64th Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics (DFD), held November 20-22, 2011, at the Baltimore Convention Center near the scenic Inner Harbor section of Baltimore, Md. Researchers from around the globe will present noteworthy research covering the intricacies of flight, the workings of the human heart, the spread of disease, explosions, wine swirling, and more.
Two Pioneer probes left our solar system carrying plaques about humankind, and two Voyager probes will soon join them to gather information about places far out in our galaxy. We can and will send more autonomous probes into outer space, but why have we never found evidence of other civilizations doing the same? A pair of postdoctoral researchers at Penn State, approaching the problem mathematically, shows that we have not looked in enough places to ensure that no extraterrestrial artifacts exist in our solar system.
International sports federations would like to be able to follow the movements of individual athletes more easily during televised matches, even when they're hidden from view. Today, EPFL's Computer Vision Laboratory announces an innovative system that accomplishes this task -- and the implications go far beyond sports.

-- An international team of scientists using NASA's Fermi Gamma-ray Space Telescope has discovered a surprisingly powerful millisecond pulsar that challenges existing theories about how these objects form.
At the same time, another team has located nine new gamma-ray pulsars in Fermi data, using improved analytical techniques.
An international team of astronomers has used a new technique to study the bright disc of matter surrounding a faraway black hole. Using the NASA/ESA Hubble Space Telescope, combined with the gravitational lensing effect of stars in a distant galaxy [1], the team measured the disc's size and studied the colours (and hence the temperatures) of different parts of the disc. These observations show a level of precision equivalent to spotting individual grains of sand on the surface of the Moon.
In the search for extraterrestrial intelligence, astronomers have hunted for radio signals and ultra-short laser pulses. In a new paper, Avi Loeb (Harvard-Smithsonian Center for Astrophysics) and Edwin Turner (Princeton University) suggest a new technique for finding aliens: look for their city lights.
"Looking for alien cities would be a long shot, but wouldn't require extra resources. And if we succeed, it would change our perception of our place in the universe," said Loeb.
Pulsars are the lighthouses of the universe. These compact and fast-rotating neutron stars flash many times per second in the radio or gamma-ray band. Pure gamma-ray pulsars are extremely difficult to find despite their high energy because they radiate very few photons per unit of time. Using an improved analysis algorithm, Max Planck scientists and international partners have now discovered a number of previously unknown gamma-ray pulsars with low luminosity in data from the Fermi satellite. These pulsars had been missed using conventional methods.
The reddest galaxies with the largest central bulb show the largest bars -gigantic central columns of stars and dark matter-, according to a scientific study that used Google Maps to observe the sky. A group of volunteers of more than 200,000 participants of the galaxy classification project Galaxy Zoo contributed to this research.
WASHINGTON -- The federal government should embark on a coordinated, funded, and sustained effort to dispose of approximately 45,000 excess and underutilized facilities, says a new report from the National Research Council. Approximately $1.6 billion is spent annually to operate and maintain federal facilities that are no longer needed to support federal agencies' missions.
SAN FRANCISCO –November 3, 2011– A new study sponsored by NASA finds that space flights lasting six months or more can cause a spectrum of changes in astronauts' visual systems. Some problems, including blurry vision, appear to persist long after astronauts' return to Earth. The results are affecting plans for long-duration manned space voyages, such as a trip to Mars. The study team included ophthalmologists Thomas H. Mader, MD, of Alaska Native Medical Center and Andrew G. Lee, MD, of The Methodist Hospital, Houston, Texas.
The TRMM satellite passed directly above a recently formed tropical cyclone in the Arabian Sea on November 2, 2011 at 0350 UTC (11:50 p.m. EDT, Nov. 1). An analysis of rainfall was done using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. TRMM data showed that rainfall rates with tropical storm Keila ranged from light to moderate along the south-eastern coast of Oman. Moderate to heavy rainfall was revealed to be spiraling into Keila's center of circulation in the Arabian Sea near the southeastern coast of Oman.
