Fort Davis, Texas — NASA's Kepler mission has found the first multi-planet solar system orbiting a binary star, characterized in large part by University of Texas at Austin astronomers using two telescopes at the university's McDonald Observatory in West Texas. The finding, which proves that whole planetary systems can form in a disk around a binary star, is published in the August 28 issue of the journal Science.

NASA and NOAA satellites continue to provide detailed information on Hurricane Isaac as the storm bears down on the U.S. Gulf coast. NASA's TRMM and Terra satellites captured imagery, and NOAA's GOES-13 satellite provided animations of Isaac's march toward the coast today, Aug. 28.
Tropical Storm Bolaven weakened as it moved north through the cooler waters of the Yellow Sea in the last day, which is good news for North Korea and southeastern China where it is making landfall today, Aug. 28.
On July 8, 2011 the Space Shuttle Atlantis launched for the very last time. On that historic day, as the world watched its last ascent up into orbit and commentators discussed the program's contributions to space flight and scientific research over 20 years, the shuttle helped spawn one last experiment. As the shuttle reached a height of about 70 miles over the east coast of the U.S., it released – as it always did shortly after launch – 350 tons of water vapor exhaust.
ANN ARBOR, Mich.---What if every U.S. worker got an automatic 10 percent pay raise at age 55? According to a new University of Michigan study, most people would work quite a bit longer to enjoy the extra income before they retired.
By eliminating social security payroll taxes starting when workers are 55-years old, the study shows that take-home pay would jump by 10.6 percent and they would work 1.5 years longer on average, paying more income taxes and helping to reduce the Federal deficit.
Gravitational waves, much like the recently discovered Higgs boson, are notoriously difficult to observe. Scientists first detected these ripples in the fabric of space-time indirectly, using radio signals from a pulsar-neutron star binary system. The find, which required exquisitely accurate timing of the radio signals, garnered its discoverers a Nobel Prize. Now a team of astronomers has detected the same effect at optical wavelengths, in light from a pair of eclipsing white dwarf stars.
On Aug. 28 at 8:40 a.m. EDT, a visible image of Tropical Storm Isaac taken from NOAA's GOES-13 satellite showed the huge extent of the storm, where the eastern-most clouds lie over the Carolinas and the western-most clouds are brushing east Texas. The image was created by the NASA GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center of circulation, making the storm about 410 miles in diameter.
NASA satellites are providing imagery and data on Typhoon Tembin southwest of Taiwan, and Typhoon Bolaven is it barrels northwest through the Yellow Sea. In a stunning image from NASA's Aqua satellite, Bolaven appears twice as large as Tembin.
NASA's Atmospheric Infrared Sounder or AIRS instrument is an infrared "eye" that flies onboard NASA's Aqua satellite. AIRS has been providing the National Hurricane Center with valuable temperature data on Isaac's clouds and the surrounding sea surface temperatures, and a time series of data shows that Isaac is consolidating.
The blanket of sea ice floating on the Arctic Ocean melted to its lowest extent ever recorded since satellites began measuring it in 1979, according to the University of Colorado Boulder's National Snow and Ice Data Center.
Scientists have long suspected that the Sun's 11-year cycle influences climate of certain regions on Earth. Yet records of average, seasonal temperatures do not date back far enough to confirm any patterns. Now, armed with a unique proxy, an international team of researchers show that unusually cold winters in Central Europe are related to low solar activity - when sunspot numbers are minimal. The freezing of Germany's largest river, the Rhine, is the key.
Harvard scientists have, for the first, time created a type of "cyborg" tissue by embedding a three-dimensional network of functional, bio-compatible nanoscale wires into engineered human tissues.
Boston, Mass.—A multi-institutional research team has developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks—which mark the first time that electronics and tissue have been truly merged in 3D—allow direct tissue sensing and potentially stimulation, a potential boon for development of engineered tissues that incorporate capabilities for monitoring and stimulation, and of devices for screening new drugs.
Sunbathing may be healthy – at least for one group of North American insects that apparently uses the activity to fight off germs, Simon Fraser University scientists have found.
Western Boxelder bugs (WBB), found largely in B.C. interior regions, are known to group together in sunlit patches and while there, release monoterpenes, strong-smelling chemical compounds that help protect the bugs by killing germs on their bodies.
NASA's Tropical Rainfall Measuring Mission satellite, known as TRMM has been monitoring the rainfall rates within Tropical Storm Isaac as the storm entered the eastern Caribbean Sea.
