NASA satellites continue to capture important wind speed and cloud data that forecasters at the National Hurricane Center are using to help their forecasts. QuikScat has been particularly helpful in determining the extent of hurricane and tropical storm-force winds, and they go a great distance.

Durham, N.C. – Researchers at Duke University Medical Center may have a new way to stop and even prevent the urinary tract infections (UTIs) that plague more than a third of all adults, some of them repeatedly.
The researchers have discovered how cells within the bladder are able to sense the presence of E. coli bacteria hiding within compartments in the bladder's own cells. This starts a process that then kicks them out.
ANN ARBOR, Mich. — Hospitals that treat more black cancer patients have worse survival rates on average for patients with breast and colon cancer, regardless of race, according to a new study from the University of Michigan Comprehensive Cancer Center.
The research helps explain why African-Americans with breast or colon cancer are less likely than white patients to survive the disease.
A team of scientists associated with the LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration and the Virgo Collaboration has completed new research on the origin of the universe and the results will appear in the journal Nature.
Pasadena, Calif.—An investigation by the LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration and the Virgo Collaboration has significantly advanced our understanding the early evolution of the universe.
GAINESVILLE, Fla. --- An investigation by a major scientific group headed by a University of Florida professor has advanced understanding of the early evolution of the universe.
The dense star cluster RCW 38 glistens about 5500 light years away in the direction of the constellation Vela (the Sails). Like the Orion Nebula Cluster (ESO 12/01), RCW 38 is an "embedded cluster", in that the nascent cloud of dust and gas still envelops its stars. Astronomers have determined that most stars, including the low mass, reddish ones that outnumber all others in the Universe, originate in these matter-rich locations. Accordingly, embedded clusters provide scientists with a living laboratory in which to explore the mechanisms of star and planetary formation.
Scientists from NRL's Space Science and Remote Sensing Divisions, in collaboration with researchers from the University of New Mexico (UNM) and the National Radio Astronomy Observatory (NRAO) located in Socorro, N.M., have generated the first scientific results from the Long Wavelength Demonstrator Array (LWDA). The measurements were obtained during field tests and calibration of two prototype antennas for the much larger Long Wavelength Array (LWA), which will eventually consist of nearly 13,000 similar antennas.
If some day you are tested for the H1N1 virus without the painful prick of a needle, thank a pig -- and a team of Kansas State University researchers and their collaborators who are connecting animal and human health.
K-State professors Dick Hesse and Bob Rowland -- along with a research partner at Iowa State University -- are collaborating with Susan Wong, a scientist at the New York State Department of Health, on diagnostic and intervention tools for the H1N1 virus.
Bill was the third tropical depression in the Atlantic Ocean hurricane season, behind Ana and Tropical Depression One. Over the weekend Bill grew into the first hurricane in the Atlantic this season. Two NASA Satellites captured Bill's rainfall and cloud temperatures as he was powering up.
Claudette's center had moved into southwestern Alabama and weakened into a tropical depression. She'll turn toward the north-northwest later today and soak Alabama with up to 10 inches of rain in some isolated areas.
At 2 a.m. EDT on Monday, August 17, Tropical Storm Claudette made landfall near Fort Walton Beach, Florida with maximum sustained winds near 50 mph. When it made landfall, tropical storm force winds extended 70 miles from the center.
GREENBELT, Md. - NASA scientists have discovered glycine, a fundamental building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft.
"Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet," said Dr. Jamie Elsila of NASA's Goddard Space Flight Center in Greenbelt, Md. "Our discovery supports the theory that some of life's ingredients formed in space and were delivered to Earth long ago by meteorite and comet impacts."
GREENBELT, Md.--Solar physicists at NASA have confirmed that small, sudden bursts of heat and energy, called nanoflares, cause temperatures in the thin, translucent gas of the sun's atmosphere to reach millions of degrees.
The sun's outer atmosphere, or corona, is made up of loops of hot gas that arch high above the surface. These loops are comprised of bundles of smaller, individual magnetic tubes or strands that can have temperatures reaching several million degrees Kelvin (K), even though the sun's surface is only 5,700 degrees K.
There are a lot of ups and downs in tropical cyclone formation in the Pacific Ocean this week, and that's keeping NOAA's GOES-11 satellite busy. There are remnants of Maka and Tropical Depression 9E, a fizzled Felicia, and a new Tropical Storm named Guillermo.
The graphics folks that create images from the satellite at the GOES Project at NASA Goddard Space Flight Center in Greenbelt, Md. are posting updated images on the GOES Project website often and forecasters are watching them.
Taking advantage of advanced techniques to correct distortions caused by Earth's atmosphere, astronomers used the NSF-supported Gemini Observatory to capture the first images of clouds over the tropics of Titan, Saturn's largest moon.
The images clarify a long-standing mystery linking Titan's weather and surface features, helping astronomers better understand the moon of Saturn, viewed by some scientists as an analog to Earth when our planet was young.
